Dynamic switch-in/off device for use on low-voltage reactive compensating equipment

The utility model discloses a dynamic switching device used for low voltage reactive compensating equipment. One end of an air switch k 0 is connected with one end head Jm of a bus bar, the other end is connected with one end of a rapid air switch K, the other end of the rapid air switch K is connected with the input end of a zero cross control type AC electronic switch M, the output end of the zero cross control type AC electronic switch M is connected with the end head Jc of a compensation power capacitor, and the triggering end of the zero cross control type AC electronic switch M is connected with the end head Y of an electronic controller. The utility model is suitable for replacing the mechanical type switching device of the existing low voltage reactive compensating equipment, and can ensure that the low voltage reactive compensating equipment can be normally operated at the dynamic switching time.
