Switchgear bulk remote monitoring method, switch bulk remote monitoring system

摘要

PPROBLEM TO BE SOLVED: To reduce costs for collectively and remotely monitoring operation of each switch of an electric supply station. PSOLUTION: A remote monitoring control device 200 transmits an operation command to a switch being an operation target and outputs an operation log of the switch being the operation target. A switch collective monitoring device 100 measures a master current I1 flowing in a wiring circuit breaker MCCB2 of a control power supply so as to record it as a control current waveform of the switch being the operation target during a period from the start of operation of the switch as the operation target until the end of the operation. The switch collective monitoring device 100 detects a time period during which the control current flows on the basis of the recorded control current waveform as the operating time of the switch being the operation target. The switch collective monitoring device 100 transmits an operating time signal S2, indicating the detected operating time of the switch being the operation target, to the remote monitoring control device 200. The remote monitoring control device 200 outputs an operating time log of the switch being the operation target indicated by the operating time signal S2 received from the switch collective monitoring device 100 successively after the output of the operation log.
