Description

Technical Field

[0001] This utility model relates to the field of partial discharge monitoring technology, specifically a comprehensive monitoring device for partial discharge of power equipment. Background Technology

[0002] Partial discharge monitoring is a technical means to detect and analyze partial discharge phenomena inside electrical equipment.

[0003] There are various methods for monitoring partial discharge, such as pulsed current method, ultra-high frequency method, ultrasonic method, and chemical method.

[0004] Pulse current method: By measuring the pulse current caused by partial discharge on the neutral point or grounding point of the power equipment through the measuring impedance on the coupling capacitor side, information such as discharge quantity, discharge phase, and discharge frequency can be obtained.

[0005] Ultra-high frequency (UHF) method: Partial discharge generates UHF electromagnetic wave signals, which are then received and monitored using UHF sensors. This method has strong anti-interference capabilities and can detect small amounts of partial discharge. It can be used for online monitoring of equipment such as GIS and switchgear. For example, the UHF ultrasonic partial discharge online detector is based on this principle.

[0006] When using the above-mentioned equipment, the relative position between the monitoring end and the electrical equipment being monitored is not easy to install and fix, which affects its use. Utility Model Content
