Remote control device for one-key sequential control operation of transformer substation

Abstract

The remote control device comprises a monitoring host, a switch, a control assembly and a wire spring type protection pressing plate, the control assembly comprises an execution mechanism and a micro circuit breaker control mechanism, and the wire spring type protection pressing plate and the micro circuit breaker control mechanism are each connected with a communication control unit. The communication control unit is connected with the monitoring host through the switch; the air switch has the advantages that a control instruction is issued to the communication control unit through the monitoring host, the wire spring type protection pressing plate and the micro circuit breaker control mechanism receive the instruction of the communication control unit, opening and closing control over the wire spring type protection pressing plate is achieved, and the micro circuit breaker control mechanism controls the execution mechanism to conduct opening and closing control over the air switch; and the state information of the wire spring type protection pressing plate and the state information of the air switch can be fed back to the monitoring host, so that closed-loop control is realized, remote control operation of the protection pressing plate and the air switch is realized, the working efficiency of operation and maintenance is greatly improved, and the safety risk on the way can be greatly reduced.

Description

technical field [0001] The invention relates to a remote control device for one-button sequential control operation of a substation. Background technique [0002] With the continuous development of substations towards intelligence and informationization, the operation of power equipment in the substation will gradually adopt the remote control operation mode to replace the manual on-site operation mode. At present, the State Grid Corporation and the China Southern Grid Corporation are vigorously promoting the one-button sequential control operation mode, and the primary equipment of the substation has basically realized remote control operation. However, for the secondary equipment that cooperates with the primary equipment in the switching operation, such as the secondary pressure plate and the circuit breaker, its informationization and intelligence level is relatively low, and it still needs to be manually operated at the station end, which greatly restricts the one-key s...

However, for the secondary equipment that cooperates with the primary equipment in the switching operation, such as the secondary pressure plate and the circuit breaker, its informationization and intelligence level is relatively low, and it still needs to be manually operated at the station end, which greatly restricts the one-key sequence. The further advancement of the control operation, and the high risk of vehicle safety on the road, the low efficiency of operation and maintenance
