Processing program for automatic switching experiment device of capacitor compensation cabinet

Abstract

The invention relates to a processing program for an automatic switching experiment device of a capacitor compensation cabinet. The processing program includes that a phase-B power source and a phase-C power source are adopted respectively, and phase angle difference of 1200 of two phases is utilized; phase angle lag of the phase B and the phase C is adopted, and zero potential of the automatic switching experiment device of the capacitor compensation cabinet is converted and input into a capacitor switching controller, so that the capacitor compensation cabinet is enabled to automatically switch in; phase angle advance of the phase B and the phase C is adopted, and zero potential of the automatic switching experiment device of the capacitor compensation cabinet is converted and input into the capacitor switching controller, so that the capacitor compensation cabinet is enabled to automatically switch out. In this way, active power consumption caused by taking an inductor or a motor as load is reduced, power supply current is reduced, and automatic switching experiment cost of a capacitor is lowered; connection with the inductor or the motor serving as the load is not needed any more, and wiring of automatic switching operation of the capacitor is quite convenient, so that economic loss is reduced greatly for testing technology.

Description

technical field [0001] The invention belongs to the field of electromechanical manufacturing, and in particular relates to a processing program of an automatic switching test device for a capacitance compensation cabinet. Background technique [0002] In industrial power distribution, the inductive load parallel capacitor can improve the power supply quality and power factor; because the inductive load consumes active power, the current also increases, which increases the loss of electric energy, and the parallel capacitor is used. The working power is opposite to the direction of the inductance and cancels each other out, thereby improving the power supply quality, improving the power factor, reducing the supply current, and reducing the cross-sectional area of ​​the power supply cable, thereby increasing the cost. At present, the existing automatic switching test device of capacitance compensation cabinet is carried out by inductor load or high-power motor load, but th...

Problems solved by technology

At present, the existing automatic switching test device of capacitance compensation cabinet is carried out by inductor load or high-power motor load, but the inductor load or motor load consumes active power, and the increase of current increases the loss of electric energy, thereby improving The cost of the automatic switching test of the capacitor is reduced, and the inductor or the motor requires a lot of cost to purchase and maintain, which will not only increase the test cost, but also make it very inconvenient to operate the wiring
