GGD Capacitance Compensation Cabinet

1. Overview:

Most load types in power system belong to inductive load. In addition, power electronic devices are widely used in power enterprises, so the power factor of power grid is low. Lower power factor reduces equipment utilization ratio, increases power supply investment, damages voltage quality, reduces equipment service life, and greatly increases line loss. In order to improve the energy waste caused by the low power factor of power grid and these unfavorable factors of power supply production, it is necessary to effectively improve the power factor of power grid. Obviously, it is unreasonable and usually impossible for these reactive power to be supplied by generators and transmitted over long distances. Reasonable way is to generate reactive power where reactive power is needed, that is, to increase reactive power compensation equipment and devices.

1. Structure Composition

Generally speaking, low price Capacitance Compensation Cabinet is composed of cabinet shell, bus, circuit breaker, disconnector, thermal relay, contactor, lightning arrester, capacitor, reactor, primary and secondary conductor, terminal row, power factor automatic compensation control device, panel instrument, etc.

III. Basic Principles

In the actual power system, most of the loads are asynchronous motors. The equivalent circuit can be regarded as a series circuit of resistance and inductance. The phase difference between voltage and current is large and the power factor is low. After shunt capacitors are connected, the current of capacitors will offset part of the inductance current, so that the inductance current decreases, the total current decreases, the phase difference between voltage and current decreases, and the power factor increases.

A reactive power automatic controller is installed in the compensation cabinet, which automatically puts in or removes capacitors according to the load force rate. The main function of the controller is to make the load close to the required reactive current, thereby improving the power factor. For enterprises, the main reason is to avoid the penalty of power factor not up to the standard ().

 (H) RW 12-24 Outdoor High Voltage Drop Fuse

1. Use

(H) RW 12-27 drop fuse and pull-load drop fuse are outdoor high-voltage protective appliances, which are assembled on the high-voltage side of distribution transformer or branch lines of distribution line, and are used for overload and short-circuit protection of transmission lines and power transformers and for sharing rated load current.

2. Brief introduction of structure

The drop fuse consists of two parts: insulating bracket and fuse pipe. The static contacts are installed at both ends of the insulating bracket, and the movable contacts are installed at both ends of the fuse pipe. The fuse pipe consists of an inner arc extinguishing tube and an outer epoxy glass tube. Pull-load drop fuse adds elastic auxiliary head and arc extinguishing cover to divide and close load current. When a drop fuse is in normal operation, the fuse pipe is tensioned by means of the fuse.

Then a closed position is formed. When the system fails, the fault current causes the fuse to fuse rapidly and form an arc. The arc extinguishing tube is heated by the arc and decomposes a large number of gases, which forms a high pressure in the tube and blows longitudinally along the pipeline. The arc is rapidly elongated and extinguished. After the fuse is fused, the lower moving contact loses tension and turns down. The locking mechanism releases the fuse tube, and the fuse tube falls down, forming an obvious breaking position. When the load needs to be pulled, the contact is pulled by the insulating rod. At this time, the active and static contacts are still in contact. The contacts are pulled by the insulating rod, and the auxiliary contacts are separated. Arc is generated between the auxiliary contacts. The arc is elongated in the slot of the arc extinguishing hood. At the same time, the arc is extinguished when the current passes zero.
