Example Embodiment
[0028] The implementation example of the intelligent online monitoring system for high-voltage switchgear is as follows:
[0029] Such as figure 2 In the monitoring device shown, the system comprehensively monitors the switchgear through the partial discharge online monitoring system and the switchgear temperature measurement system, and realizes the comprehensive monitoring of the switchgear from different angles such as electricity, sound, and characteristic spectrum. figure 2 The sensors mainly include temperature sensors, partial discharge ultrasonic sensors, HFCT partial discharge sensors, and transient ground voltage sensors. Installation of composite partial discharge monitoring sensor The composite partial discharge sensor integrates three detection modes: ultrasonic sensor, UHF, and TEV. Adsorption is installed on the wall of the cable room, and the height is less than 50mm to ensure a safe distance. A strong magnet is embedded at the bottom of the sensor, which can be...
