The maintenance of power circuit divides feed end and receiving end, and this device will be installed in feed end, comes control circuit to send.Operation principle of this device and workflow summary:
Whether line maintenance begins, and device at first detects the circuit-breaker status signal, detect circuit breaker and separate;
Whether device is charged by the non-contact sensor detection line, charged as circuit, then can not give the electric locking device energising of control isolation switch, disconnecting link can't separate, and prevents charged minute disconnecting link, burns out disconnecting link equipment, after having only line outage, device carries out logic determines according to operation rules, just can switch on to electric locking, and operating personnel can carry out the isolation switch separate operation;
After disconnecting link separates, the charged signal of circuit that the device pick-up transducers detects in real time, carry out logic determines, the display operation information, confirm to export when circuit does not have electricity control signal and open ground connection disconnecting link locking device, operating personnel close ground cutter (or earth connection) operation, and maintenance beginning, this step operation can the imperative operation personnel can not closed the ground cutter under circuit have the situation of electricity;
After getting togather ground connection, p-wire is suspended on the detection line, p-wire has three, be suspended to the A of circuit respectively, B, on the C three-phase line, three p-wires couple together circuit and device, ground state on the detection line, p-wire has auto-lock function, after p-wire is suspended on the circuit, can't take between turn(a)round, can prevent artificial destruction maintenance flow process like this, realize positive action;
After line maintenance finished, monitoring host computer output control signal was opened ground connection disconnecting link locking device, and operating personnel carry out branch ground cutter (or earth connection) operation; Whether the ground connection that this moment, device can utilize p-wire to detect between the other side transformer station and two transformer stations extracts, as ground connection excision is arranged on the circuit, device can can't close disconnecting link and send electricity to the energising of the electric locking device on the isolation switch, send electrification to take place to prevent band ground connection;
After device detects the whole excisions of line-to-ground, LCD can be pointed out the withdrawal p-wire, at this moment, p-wire must be regained, and be connected, otherwise can't carry out next step operation with the device to test line interface, after having only p-wire to hang return device, device just can be exported control signal control isolation switch locking device and open, and operating personnel carry out the isolation switch closing operation, and whole maintenance flow process finishes.
Monitoring host computer of the present utility model adopts Single-chip Controlling, has functions such as liquid crystal display, storage, time showing, cipher control.LCDs can be to each step operation display reminding menu, and pilot operationp personnel operate by flow process, can send sound and light alarm for faulty operation, and alert is noted.The memory cell of device is carried out automatic record to the concrete time and the operating procedure situation of inspection operation each time, so that inquiry in the future.In the time of need opening electric locking for special circumstances, device can require operator's input manager password temporarily, can operate, but device can be write down this operating process, arbitrarily operates to prevent personnel.
Compare with existing error-proof device, the utility model has been combined circuit band electro-detection, line-to-ground detection with electric locking Come, by the signal that detects, carry out logic according to the electric anti-misoperation rule and judge, the folding of control electronic blocking device, Prevent that effectively charged branch (closing) disconnecting link, charged cutter from sending the generation of the accidents such as electricity with closing ground cutter, band, makes whole line maintenance flow process More safe and reliable.
The utility model can be widely applied to the line maintenance security monitoring of 10KV-500KV transformer station.
