Smart isolating switch operation system design based on IGBT

Aiming at the movable contact motion of the isolating switch during the operation lack of precision control and complex control circuit leading to the difficult clearing of a fault, a kind of smart isolating switch operation system with centralization ,visualization and intelligence are presented. The system based on insulated gate bipolar transistor(IGBT) variable voltage and variable frequency technology realized the precision control of the movable contact motion process of the isolating switch, by the analysis and integration of the original control circuit, each logic visualization of the isolating switch control circuit has been realized. The results show that the system can satisfy the technical demands for the isolating switch opening and closing, which effectively improve control precision and intelligent level of the switch operation.
