Intelligent reclosing device and method based on vacuum triggering switch

The invention provides an intelligent reclosing device and method based on a vacuum triggering switch. The device comprises a high-voltage circuit breaker, the vacuum triggering switch, an intelligent controller, and a triggering loop. The intelligent controller is used for controlling the high-voltage circuit breaker and the triggering loop, collecting the voltages and currents of a bus incoming end and a bus outgoing end in real time, and judging whether the high-voltage circuit breaker carries out reclosing or not according to the voltages and currents. The triggering loop is used for receiving a triggering command of the intelligent controller, and triggering the vacuum triggering switch to be switched on. The vacuum triggering switch is in parallel connection with the high-voltage circuit breaker. One end of the high-voltage circuit breaker is connected with the bus incoming end and the intelligent controller, and the other end of the high-voltage circuit breaker is connected with the bus outgoing end. The other end of the intelligent controller is connected with the triggering loop, and the other end of the triggering loop is connected with the vacuum triggering switch. The device achieves the switching-on of the high-voltage circuit breaker after a fault of a high-voltage loop, improves the reclosing accuracy, and improves the stability and safety of a power grid.
