Abstract

The invention discloses a gas-insulation completely-enclosed combined electrical appliance monitoring device and system. The device comprises a detector, a communication device and a server. The detector is used for detecting the discharging signals of a gas-insulation completely-enclosed combined electrical appliance GIS; the communication device receives the partial discharging signals in a manner of wireless communication and transmits the partial discharging signals to the server; the server is used for determining the failure type of the GIS according to the partial discharging signals. By the aid of the device, the problem that the GIS partial discharging monitoring system is complex in structure in the prior art is solved, and the effect of simplifying the GIS partial discharging monitoring system structure is achieved.

Description

technical field [0001] The invention relates to the field of electric equipment, in particular to a monitoring device and system for a gas-insulated fully enclosed combined electric appliance. Background technique [0002] With the rapid development of my country's power industry construction, the modern power system is developing in the direction of large power grids, large units, ultra-high voltage, and large capacity. In order to ensure the stability and reliability of the power system, more safety requirements for power equipment are also proposed high demands. [0003] GIS (Gas Insulation Switchgear, referred to as GIS) is a gas-insulated fully enclosed combined switchgear, which is very common in power grids and large substations. It assembles all kinds of switchgear in the power system in a closed metal case, and then fills it with SF 6 gas to achieve good insulation from the outside. [0004] The safe operation of GIS is very important to the stability of the power...
