Description

Relay protection clamp plate state on-line monitoring system Technical Field The invention relates to the field of relay protection, in particular to an online monitoring system for the state of a relay protection pressing plate. Background With the continuous improvement of equipment monitoring technology and network communication technology, the safety management requirements of production sites on equipment are gradually improved, unmanned and less duty modes are continuously popularized, and the intelligent and intelligent construction of a power plant comes in a homeowner. The traditional relay protection device, protection clamp plate state only inserts protection device, and electric power system considers protection device's safety, reliability and has forbidden other systems of access through the network mode, and each power plant, transformer substation protection device's clamp plate state can only carry out the scene through artifical observation mode at present and check, under automation, intelligent construction, through this scheme, under the prerequisite that does not change original protection device, through the on-line monitoring system who builds a whole set of automatic monitoring protection device clamp plate, realizes the on-line monitoring to protection device clamp plate. The method is characterized in that the state of a pressing plate of a protection device is used for monitoring, an existing special communication network is used for converging information of each protection device on a relay protection information management substation platform, and the state of the pressing plate of the protection device is monitored on line through the relay protection information management substation. But monitor the protection device clamp plate state through protection information management sub-station, be limited by protection device's function at present, the clamp plate state has only gathered the device function clamp plate in the protection device income volume, does not monitor protection device export clamp plate state, protection information management sub-station is as the supervisory equipment who goes up power transmission net dispatch center simultaneously, and fixed mounting is in each factory station protection room, can't extend to other places in the factory and monitor, although protection device's function clamp plate state can realize remote monitoring at protection information management sub-station, but protection device export clamp plate state can only carry out on-the-spot visual through personnel, register the monitoring.
