Abstract

The invention relates to a switch and particularly relates to a single-phase capacitor switching switch. The switch comprises a lower casing and an insulating cylinder which is installed on an upper side of the lower casing, an insulating pull rod is installed between the lower casing and the insulating cylinder, a conductive clip is installed in the insulating cylinder, the insulating cylinder atan upper end of the conductive clip is equipped with a vacuum tube, the lower casing is internally equipped with a permanent magnet structure coil which is connected to a switch-off handle and a switch-off rod through a first switch-off spring, a main shaft is installed in the lower casing, and a side of the main shaft is equipped with a spring mechanism. The intelligent separate compensation inthe field of high-voltage capacitor switching can be achieved. A problem that the intelligent separate compensation cannot be achieved and only common compensation can be achieved in the field of high-voltage capacitor switching at present is solved in the aspect of electric energy quality required by the nation.

Description

technical field [0001] The invention relates to a switch, in particular to a single-phase cut capacitor switch. Background technique [0002] The inrush current that will be generated when the capacitor is switched on, the size of the inrush current is related to the line impedance and the voltage difference between the capacitor and the power supply when the capacitor is switched on. In extreme cases, the inrush current can exceed 100 times the rated current of the capacitor. In order to reduce the inrush current when the capacitor is switched on, a special contactor for switching capacitors appears. The basic principle of this type of device is to use the current limiting resistor to first connect the circuit to precharge the capacitor, thereby reducing the voltage difference between the power supply and the capacitor, and then the main The contacts short out the current limiting resistor. Such devices can usually reduce the inrush current to less than 5 times, but the a...
