Processing program for automatic switching experiment device of capacitor compensation cabinet

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.
