Problems solved by technology

[0004] However, once the isolating switch isolates the faulty circuit, it will cause the working unit connected to the circuit to stop working, so that there will be no problem with the remaining shunts, because the entire circuit cannot operate after isolation, especially in some factories.

Abstract

The invention relates to an isolating switch, in particular to a combined indoor isolating switch capable of shunt detection and whole-path operation. The isolating switch comprises a power supply unit, an isolation unit and a working unit, the power supply unit comprises a main power supply, and the output end of the main power supply is electrically connected with the working unit. According to the invention, the circuit detection unit detects the electrified shunt and sends the state information of the electrified shunt to the standby power supply, the standby power supply of the power supply unit receives the state information, and the standby power supply supplies power to the electrical elements connected with the non-electrified shunt only in the state that the electrical elements on the electrified shunt are not damaged. Therefore, the safety of each power supply branch is ensured through a mode of detecting and then supplying power, the operation of the whole circuit is completed, and the working efficiency of the working unit is ensured.

Description

technical field [0001] The invention relates to an isolating switch, in particular to a combined indoor isolating switch capable of split-circuit detection and whole-circuit operation. Background technique [0002] The isolating switch is mainly used for "isolating power supply, switching operation, connecting and cutting off small current circuits", and is a switching device without arc extinguishing function; [0003] When the isolating switch is in the off position, there is an insulation distance between the contacts that meets the specified requirements and an obvious disconnection mark; Current switching equipment; generally used as a high-voltage isolation switch, that is, an isolation switch with a rated voltage above 1kV. [0004] However, once the isolating switch isolates the faulty circuit, it will cause the working unit connected to the circuit to stop working, so that there will be no problem with the remaining shunts, because the entire circuit cannot operate...
