The switching capacitor contactor (hereinafter referred to as contactor) is a special contactor for switching on and off a low-voltage parallel capacitor, is widely used in reactive power compensation equipment for automatic compensation, and is suitable for switching on and off the capacitor to 90kvar in an electric power system with the alternating current frequency of 50hz and the rated working voltage of 380v so as to improve the power factor. The contactor is of a building block type, the resistance circuit part is arranged above the main circuit part, and the resistance circuit is three paths. The main contact has reasonable design, independent load and reliable work. The early-connection contact of the series resistor is a resistor switching circuit, when the electromagnetic coil of the contactor is electrified, the resistor switching circuit is switched on in advance, current charges the capacitor through the resistor, the resistor inhibits the switching-on inrush current of the capacitor, and then the main contact is closed to bear capacitance current.
