The low-voltage power grid is the lowest-grade power grid directly facing terminal users to supply power and is also the power grid which is most widely distributed in China, and power supply enterprises usually do not examine the power factors of low-voltage transformer districts with contract capacity smaller than 100KVA, so that power consumers under the transformer districts generally do not actively install reactive compensation devices, transformers in the transformer districts operate under the condition of under-compensation for a long time, and unnecessary electric energy loss in circuits is increased.
Nonlinear power equipment such as motors and the like operate in a power system according to the electromagnetic induction principle and perform electric energy conversion in a reactive power mode. Because the induced electromotive force generated by the inductance element can block the current change, the current lag voltage is 90 degrees, and conversely, when the current passes through the capacitance element, the voltage lag current is 90 degrees, so that the vector included angle between the current and the voltage can be obviously reduced by connecting a capacitor with proper capacity in parallel in the electromagnetic element circuit, and the power supply performance of a power grid is optimized.
The current is decomposed into an active current component and a reactive current component, and the total current in the line is increased due to the increase of the angle when reactive compensation is not carried out, so that the loss in the line is increased. After reactive compensation is carried out, the angle is reduced, reactive current components are obviously reduced, total current in the line is reduced, and line loss is reduced.
Install self-healing low pressure shunt capacitance ware additional at the motor switch load side to the enterprise, adopt the fixed capacity compensation mode to realize idle balance on the spot, but some enterprise's production environment is comparatively mixed and disorderly, and condenser and power off switch adsorb more dust easily, and inconvenient often clear up again, therefore we propose one kind and install the idle compensation on the spot of constant volume of user side additional.
