Abstract

The invention discloses a remote-control high-voltage switch, which relates to the field of the control device of the high-voltage switch equipment. The shortcomings of complex operation, time consuming and labor consuming exist in the prior art; the remote-control high-voltage switch comprises a breaker, an isolating switch, an executive terminal and a power supply box for supplying power to the parts, and is characterized in that the breaker is connected with the isolating switch through a linkage control module; the executive terminal comprises a processor, a communication module which is connected with the processor, a switch controller, a memory and an A / D converter module. The operator in the remote control center can realize the disconnecting or connecting operation of the switch by sending commands to the executive terminal, can test voltage, current, power factor and other relevant data in a remote-control way, and can get automatic alarming for '' failure to operate, tampering, tripping operation, lack of phase, off-grid'' of the high-voltage switch; therefore, the remote-control high-voltage switch is convenient, labor-saving and time-saving, and has the effects of energy conservation, environmental protection, and convenient communication.

Description

【Technical field】 [0001] The invention relates to the field of control equipment for high-voltage switchgear, in particular to a remote-controlled high-voltage switch for a 10kv power distribution system. 【Background technique】 [0002] At present, the outdoor high-voltage switchgear of the 10KV power distribution system mostly includes a circuit breaker and an isolation switch. Because the isolation switch cannot cut off the load current, the isolation switch must be closed first, then the circuit breaker, and then the circuit breaker passes through the switch. Drive the mechanical interlock to lock; when opening, the circuit breaker must be disconnected first, then the circuit breaker drives the mechanical interlock to open, and finally the isolation switch can be separated. If the operation sequence is wrong, the isolation switch will be burned out. However, most of the existing high-voltage switches are manually operated, and the sequence is likely to be mistaken in rep...
