Background
The capacitance compensation cabinet is reactive power compensation equipment. The load types in the power system mostly belong to inductive loads, and power electronic equipment is widely used by power utilization enterprises, so that the power factor of a power grid is low. The lower power factor reduces the utilization rate of equipment, increases the power supply investment, damages the voltage quality, reduces the service life of the equipment and greatly increases the line loss. In order to improve the energy waste caused by low power factor of the power grid and the factors of unfavorable power supply production, the power factor of the power grid must be effectively improved. It is obvious that it is not reasonable, nor is it generally possible, if all of this reactive power is to be supplied by a generator and transmitted over great distances. It is reasonable to generate reactive power at the place where the reactive power is needed, i.e. to add reactive power compensation equipment and devices.

In a practical power system, most of the load is an asynchronous motor. The equivalent circuit can be regarded as a series circuit of a resistor and an inductor, the phase difference between the voltage and the current is larger, the power factor is lower, after the capacitor is connected in parallel, the current of the capacitor can offset a part of the inductive current, so that the inductive current is reduced, the total current is reduced, the phase difference between the voltage and the current is reduced, and the power factor is improved. The circuit breaker of the existing capacitor adopts a manual knife switch mode to open or break, so that the accident of hurting people by electric arcs is easy to happen.
Therefore, it is necessary to provide a trolley type low-voltage capacitor box for the above problems.
