Description

Technical Field

[0001] The utility model relates to the field of wall-mounted cabinets, in particular to a novel GIS online monitoring system monitoring unit wall-mounted cabinet. Background Art

[0002] The partial discharge online monitoring system is a system for monitoring the internal discharge of GIS. It consists of detection sensors, local substations (outdoor cabinets) and monitoring background. Due to its closed nature, GIS is very likely to cause serious equipment failures once insulation defects occur, thus causing power accidents.

[0003] GIS internal discharge is mainly divided into: tip discharge, suspended discharge, insulating gas discharge, and free particle discharge. Discharge can easily cause insulation damage, so online monitoring of the internal discharge in a closed environment such as GIS is very important. The type of discharge can be known, and an analysis of the GIS discharge trend can provide a strategy for formulating regular GIS maintenance.

[0004] The local substation is set up next to the GIS, and its internal installation and display device are connected to the wire part of the detection sensor, so as to achieve the purpose of real-time online monitoring. Generally, the wires of multiple detection sensors are connected to one display device. The wires of multiple detection sensors are prone to being messy and pulled, which in turn causes display failure. Utility Model Content
