Abstract

The invention discloses an intelligent switch state integrated online monitoring and fault diagnosis apparatus. The apparatus comprises a mechanical property state monitoring unit, an SF6 gas state monitoring unit, a lightning arrester state monitoring unit, a partial discharge state monitoring unit and an information management unit. The monitoring units and each monitoring unit and the information management unit carry out communication and data interaction through a CAN and Ethernet inside an apparatus by use of a plug-in mode. The apparatus provided by the invention can perform omni directional real-time integrated online monitoring on a mechanical property state, an SF6 gas state, a lightning arrester state and a partial discharge state of a switch body. According to parameter information of a switch state, a fusion decision analysis is made on the state of a switch by use of a fault diagnosis and data fusion technology, and a decision conclusion is obtained. The apparatus provided by the invention can communicate with a station control layer background monitoring system through an IEC61850 protocol, upload data and a diagnosis result to the background monitoring system and generate a diagnosis log and alarm signals.

Description

technical field [0001] The invention belongs to the technical field of electric device monitoring, and relates to an intelligent switch state comprehensive online monitoring and fault diagnosis device, which is especially suitable for intelligent substations designed according to the IEC61850 standard, three-phase linkage or three-phase phase separation switch states of intelligent substations of 10KV and above Comprehensive online monitoring and fault diagnosis. Background technique [0002] In recent years, with the development of new energy sources such as photovoltaics and wind power, State Grid has also vigorously promoted the construction of smart grids to meet the needs of new energy grid integration. As an important part of the smart grid, the high-voltage switch is mainly used for electrical equipment that plays the role of on-off, control or protection in power system power generation, transmission, distribution, power conversion and consumption. The stability of i...
