Key Applications of Switchgear Monitoring
- AIS Switchgear: AIS switchgear status monitoring focuses on the operating status of its internal contactors, circuit breakers and other components. By monitoring parameters such as temperature, vibration, and insulation, potential faults can be discovered in a timely manner to ensure the reliable operation of the equipment.
- MV Panel Switchgear: In addition to focusing on similar monitoring points as AIS switchgear, MV panel switchgear status monitoring also needs to focus on the status of vacuum circuit breakers, busbar temperature, cable joint temperature, etc. For MV panel switchgear insulated with SF6 gas, the pressure and purity of SF6 gas also need to be monitored.
- GIS Switchgear: GIS switchgear status monitoring mainly focuses on the pressure and purity of SF6 gas, partial discharge, temperature and humidity. Since SF6 gas is the insulating medium of GIS switchgear, its status directly affects the insulation performance of the equipment. Therefore, the monitoring of SF6 gas is the focus of GIS switchgear status monitoring.
