The method and process of taking Transformer Oil samples are as follows:
(1) sampling of transformer oil is necessary for the test of transformer oil. Sampling should be done on dry sunny days. The container and sampling method used in sampling have the most direct influence on whether the actual quality of oil can be truly reflected. The oil sample for the pressure test shall not be less than , and the simplified oil sample shall not be less than 1kg.
(2) the sampling container shall be a colorless glass bottle with a or 1kg wide mouth frosted glass stopper. Two or three bottles should be collected at a time for analysis and testing. Samples should be labeled with attention to sample name, source, sample date, sampler, weather conditions and other information.
(3) before the sampling container is used, it should be washed with gasoline, soap liquid or other oil removing solvent (such as trisodium phosphate), and then rinsed with water until it is not alkaline and water can flow evenly from the bottle wall. Finally, wash them several times with distilled water. Wash the sample container of 105 ℃ baking in the oven, will the cork lid tightly after cooling, before use may not open them.
(4) after sampling, wrap the glass stopper firmly with clean paper or cloth to prevent dirt and water from contaminating the bottle mouth.
(5) outdoor sampling shall be carried out in dry weather with fine weather or low humidity. During sampling, sundries such as rain, snow or sand shall be strictly prevented.
(6) for the oil in the oil storage equipment, it shall be normally left for more than 8h before sampling; Sampling on a working transformer does not require standing.
(7) before and after sampling, clean or non-wool muslin should be applied to wipe and wipe around the sampling mouth.
(8) when the oil sample of the Oil Transformer in operation is taken, the oil discharge valve or sampling valve under the oil tank should first release about 2kg of dirty oil accumulated at the bottom to clean the oil drain hole, and then take the oil sample.
(9) when taking the new oil supplemented by transformer and the oil sample that has just been filtered, the oil sample can only be taken after sufficient standing.
(10) when sampling from a small transformer without a drain pipe (or oil sample valve), glass tube can be inserted into the transformer when it is not in operation to extract the oil sample at the bottom, or the sampling can be replaced by changing oil.
(11) from the fuel tank, sampling, after open the lid, wash and dry the glass pipe insert oil, thumb pressure nozzle at the same time, after being inserted to loosen the thumb, break down the oil into the tube, then the thumb pressure pipe, glass pipe is put forward, a rotation, a drain pipe of oil, with washing sample tube, so repeated twice, and then draw sample.
(12) for sampling in batch drums, samples shall be selected at 5% of the total number of oil drums, but not less than 2 barrels. Sampling shall be carried out in whole lot of small pails or bottles at the rate of 2% of the total number of pails (bottles).
(13) when taking oil samples, the safety and fire prevention regulations on site shall be strictly observed.

What is the unexcited voltage regulation of transformer? Let's take a shared from Oil Immersed Transformer supplier.
Non-field excitation changer is relative to on-load voltage regulating, have the load tap switch need to be considered when switching to stream of transformer, ensure continuous current, not affect the power grid, but no excitation regulating power refers to the state of voltage regulation, tap-changer stream. Don't need the transformer in the concrete operation, should have the power of the transformer and load switch are cut off. If the high voltage side has isolation switch, should also open. And the transformer bushing are grounded, and then to switch the load tap switch. Of course you are dry, there is no tap switch, you can go to the tap.
When the side voltage of the transformer power supply fluctuates up and down,such as 3 Phase Transformer, the number of turns on the original side of the transformer needs to be adjusted to keep the voltage stability of the output side of the transformer as far as possible. There are usually two kinds of voltage regulation: on-load voltage regulation (with load for voltage regulation) and no-load voltage regulation (with load for voltage regulation). Because some people said in the past "no load regulation" is not accurate, it is easy to be misunderstood, that can not carry the load, and do not cut the original side of the power supply voltage, voltage regulation. Therefore,, the exact statement should be called no excitation voltage regulation, that is, the transformer in the case of no excitation voltage regulation (to cut off the original side of the transformer power supply, and then the voltage regulation).

Oil Immersed Transformer Manufacturer When the running transformer is struck by lightning, it will cause overvoltage outside the transformer due to the high potential of lightning. When some parameters of power system change, the overvoltage inside transformer will be caused by electromagnetic oscillation. The transformer damage caused by these two kinds of overvoltages is mostly the main insulation breakdown of windings, resulting in transformer faults. In order to prevent transformer fault caused by overvoltage, it is generally required to install lightning arrester protection on the high voltage side of the transformer, and also install lightning arrester on the low voltage side.
As a result of the transformer lead connection welding is not firm, joint screw loose, poor contact, causing local overheating, lead burning. In the installation of electrical appliances, the lead is too close to the oil tank, or the lead is too small in the distance between the two, when there is a strong wind or a short circuit occurs outside, the lead is subjected to the action of external force or electric power, it will swing, resulting in the short circuit between the two. If the transformer leakage phenomenon, so that the transformer is seriously short of oil, resulting in the lead part exposed to the air. The insulation level is lowered, and internal flashover and breakdown occur. In addition, if the transformer outlet occurs many short circuit, will make the winding stress deformation cause inter-turn insulation damage, and short circuit fault.

Dry Type Transformer Manufacturer shares that the transformer also has the very big development and the change in carries on the development experience, to the transformer experience process is also quite complex. Now the renewal of the transformer and generation is also relatively fast, for developing and changing process of transformer, also appeared a lot of changes in the trend of current transformer energy-saving is more strengthened, more good advantages of energy saving transformer, made on the basis of saving raw materials and energy, more to improve its efficiency.
China transformer has experienced the replacement process from S7, S8, S9, S10, S11 and other series. In the mid-1980s, the Chinese government forced the adoption of S7 series low-loss distribution transformers to phase out the high-energy transformers of jb1300-73 and jb500-64 standards that were then in operation on the power grid nationwide. Since 1998, urban and rural power grids have been upgraded nationwide, with S9 series distribution transformers replacing S7 series. In recent years, large quantities of S13 and S15 products are adopted again in the transformation of national urban network and rural network, and the no-load loss of S9 type transformer is reduced by 50-80% compared with that of S9 type transformer.
Of course, the implementation of energy-saving transformer is also a very difficult thing, due to raw materials and other factors, energy-saving transformer price is much higher than traditional transformer. In order to better promote the application of energy-saving transformers, the ministry of finance, the ministry of industry and information technology and the national development and reform commission jointly issued in 2012 the "implementation rules for the promotion and implementation of energy-saving products and energy-saving power distribution transformers for the project of benefiting the people", which provided 4-30 yuan/kva financial subsidies for energy-saving transformers. However, due to the large number of small and medium-sized transformer manufacturers, the transformer manufacturers are scattered, with excess capacity and many potential quality problems, which also limits the development of energy-saving transformer industry.
Transformer energy saving is a trend, although it is now the promotion is difficult, for the enterprise is also a problem, but slowly will continue to improve, more about the transformer energy saving problems please consult our manufacturers or attention to our website!

Three phase transformer Manufacturer shares that transformer is a kind of electric appliance that transfers electric energy or transmits signal from one circuit to another circuit by using electromagnetic induction principle. When there is an alternating current in the primary coil, an alternating flux is generated in the core, causing the voltage (or current) to be induced in the secondary coil. A transformer consists of an iron core and a coil. The coil has two or more windings. The windings connected to the power supply are called primary windings and the rest are called secondary windings.
By changing the winding ratio of the two coils, different voltages will be obtained in the second coil l. based on this principle, the transformer is a device that transforms the ac voltage, current and impedance. The primary coil and the secondary coil are wound in an appropriate ratio, which can increase or decrease the voltage in the circuit. Can be expressed by the formula, namely;
Primary voltage (U1)/ secondary voltage (U2)= primary winding number (n1)/ secondary winding number (n2)
It should be noted that any transformer can only transfer electrical energy from the primary to the secondary. The ratio of the primary and secondary voltages of a transformer is equal to the ratio of the secondary and primary currents. It can be said that the primary input power is equal to the secondary output power without considering the loss of the transformer.

3 phase transformer exporter shares that according to different situations, at present, the capacity of 630kVA and below 10kV oil-immersed transformer almost has no oil storage tank, so it is unnecessary to observe the oil level. Oil storage tank is installed in 35kV and above voltage grade or 10kV oil-immersed transformer with larger capacity. The oil level indication of oil storage tank is in such several forms as connecting pipe, pointer type oil level gauge and bellows. The connecting pipe adopts the principle of the connecting device. There is a red ball in the glass pipe to indicate the oil level, which is very intuitive. Pointer type oil level gauge some directly mark the position indicated by the pointer indicates the amount of oil in the oil storage tank, or through the different temperature corresponding curve (generally three, corresponding to the lowest temperature of the region), according to the location of the pointer conversion out of the oil in the oil storage tank; The top of the bellows is used to indicate the normal oil level of the oil storage tank with different oil temperatures (generally, the oil content of the oil storage tank is about 10% of the oil weight of the body).
The above is the common oil-immersed transformer common oil level measurement and the main way and method of understanding for your reference, for oil-immersed transformer you have any other questions please pay attention to our manufacturers or with our technical personnel to communicate and exchange it!

Transformer is the core of power equipment, such as 3 phase power transformer,which is closely related to people's production and life. It is made by using the principle of electromagnetic induction. The role of transformer in the circuit is mainly to stabilize the performance of voltage and current, making the current and voltage in the circuit more effective. The role of the transformer is still relatively large, for the role of the transformer you have to carefully understand. For common transformer related functions you need to grasp the following content:
A transformer is a component that converts voltage. In practical applications, we often need to change the voltage of the alternating current to suit various needs.
The transformer has the function of impedance transformation. Transformer primary and secondary winding number is different from the secondary reflection to the primary impedance is also different. The ratio of transformer secondary impedance Z2 to primary impedance Z1 is equal to the square of the ratio of transformer secondary winding number N2 to primary winding number N1, that is, Z2/Z1=(N2/N1)2. The impedance transformation of the transformer can make the impedance of both ends of the circuit match well, so as to transmit the maximum signal power.
The transformer from 3 phase power transformer manufacturer China has the phase transformation function, the exchange transformer coil joint, may change the signal voltage the phase. For example, using the audio input transformer in the push-pull power amplifier, the original signal and the inverting signal can be distributed to two power amplifiers, so that they can alternately amplify the positive and negative half-cycle signals.
The role of the transformer to be more carefully to master, and constantly improve the understanding, so that the transformer performance is more improved, more improved in the use of the role, so for the use, maintenance and maintenance of the transformer is a good help.

Transformer is a kind of important equipment and type, such as the three phase oil immersed transformer,which is constantly used in production and daily life. It attaches great importance to production and is also the key to improve production efficiency. But when we look at the operation of the transformer, we will find that there are a lot of pebbles around the transformer, and you will often see it in the process of transformer construction and various ground projects. Do you know why pebbles are placed around transformers?
The lower part of the oil-immersed transformer is usually called the oil discharge tank or oil discharge tank, which leads to the emergency oil pit or the emergency oil tank. In case of an accident, such as oil injection or explosion, the oil of the transformer will flow into the discharge pit through the goose-stone and then flow to the oil pool of the accident. At this time, the goose-stone under the transformer plays an isolating role to reduce the fire and help extinguish the fire. In addition, the high temperature transformer oil can reduce the fire after being cooled by goose stone. Prevent the transformer from burning when it is on fire, and the oil drain hole at the bottom of the oil drain pit will not be blocked. Oil in the transformer goose stone gap between the flow to the below, the surface to avoid oil, oil leakage when it also plays a role in cooling oil temperature, to prevent oil combustion.
Oil-immersed transformer is placed around pebbles with reason, for transformer to prevent the occurrence of fire burn out or you have more important significance and function of the land, for transformer, to enhance the efficiency of its various realization, let the transformer is more safe and efficient operation, more safety and quickly run to achieve transformer!

How much does the electromagnetism radiation of power transformer harm to the body?
Distribution transformer substation supplier shares that with the improvement of living standards, now we use a variety of electrical appliances also relatively have a lot of electromagnetic radiation, we are called electromagnetic radiation pollution. Transformer is also around us, so relative to the transformer so big power equipment, its electromagnetic radiation how much? Can cause harm to human body? Let's learn about the electromagnetic radiation of the transformer.
High quality oil transformer radiation is not harmful to human body. During the operation of transformer, transformer radiation will be generated. If the electromagnetic radiation exceeds the prescribed energy limit, electromagnetic radiation pollution will be formed. Electromagnetic radiation pollution can cause a lot of harm, among them the harm to human body basically is to cause human body plant nerve function disorder, blood pressure, blood phase is maladjusted, injure an eye even. Our mankind itself is in all sorts of electromagnetism radiate surround in, natural magnetic field, sunshine can give out the radiation with different intensity, nevertheless only when radiate intensity exceeds certain value (safe value) ability produces harm to human body, namely the electromagnetism pollution that we say commonly.
When we turn on the TV at home, the electromagnetic field around us is much stronger than the transmission line. Earth itself has a magnetic field, the earth magnetic field and magnetic fields produced by transmission facilities, can also be interesting conclusion: the magnetic field data observed in Beijing for 54 tesla, when magnetic field inversion, a maximum intensity is about 100 micro tesla, 50-100 times that of electromagnetic transmission facilities. This means that people living in the electromagnetic fields of dozens of micro-teslas can hardly feel anything, and even the workers on duty 24 hours a day in the substation will have no impact on their health.
About the electromagnetic radiation of transformer, in fact, is negligible, but for the sake of safety, or suggest that we stay away from it, so as not to harm the human body.

What is the unexcited voltage regulation of transformer? Shared by power transformers supplier.Let's take a look.
Non-field excitation changer is relative to on-load voltage regulating, have the load tap switch need to be considered when switching to stream of transformer, ensure continuous current, not affect the power grid, but no excitation regulating power refers to the state of voltage regulation, tap-changer stream. Don't need the transformer in the concrete operation, should have the power of the transformer and load switch are cut off. If there is a disconnecting switch on the high voltage side, it should also be turned on. And the bushing of the transformer are grounded, and then go to switch no load tap switch. Of course you are dry change, no tap switch, you can go to change tap.
When the voltage on the power side of the transformer fluctuates, it is necessary to adjust the number of turns on the primary side of the transformer, so as to keep the output voltage of the secondary side of the transformer as stable as possible. Generally, there are two kinds of voltage regulation: on-load voltage regulation (with load) and no-load voltage regulation (without load). As someone said in the past "no load voltage regulation" is not accurate, easy to be misunderstood, that can not carry the load, without cutting the original side of the supply voltage, voltage regulation. Therefore, the exact words should be called no excitation voltage regulation, that is, the transformer without excitation under the condition of voltage regulation (to cut off the original side of the transformer power supply, voltage regulation)...

Product Description
The products implement the National Standard GB1094-2013 Power Transformer and GB / T6451-2015 Three-phase Oil-immersed Power Transformer Technical Parameters and Requirements, and are recommended as the major equipment products for the national urban and rural power grid construction and retrofit by the State Economic and Trade Commission.
S11 series transformer adopts high quality material for copper winding, especially applying the new technology and new material for the coil insulation and active parts, thus the no-load and the load loss are obviously reduced, the performance and structure are more reliable and superior.
Product Features
The no-load loss for S11 series products decreased averagely, no-load current decreased on S9 series.
Transformer tank adopts hermetical structure, tank and tank cover can be connected by bolts or welded firmly, the transformer oil won’t contact with air, so that extend the service life effectively.
Improve the relevant sealing parts for the tank, increase the reliability and advance the technical level to ensure the reliability of the seal.
S11-M series transformer tank uses the corrugated plate radiator. When the oil temperature changes, the corrugated plate will proceed thermal expansion, which can replace the role of the oil conservator. the corrugated plate tank has beautiful appearance, less occupied area.
