Online monitoring of high-voltage switchgear installation

Abstract

The high-voltage distribution device is an important part of the power supply system which shoulders the dual tasks of control and protection. The function of the high-voltage distribution device is closely related to the safe operation of the power supply system. The condition monitoring of high-voltage distribution device can detect the specific parts of the fault in a timely and effective way which can improve the stability of the system. The mechanical vibration signal of circuit breaker body in mine high-voltage distribution device is a rich information carrier which contains a large number of device operating status information. Using modern information processing technology, the special parameters of mechanical faults are extracted from vibration signals, which have very important practical significance. Based on the analysis of the common mechanical faults in the high-voltage power distribution unit, a set of online vibration signal processing system with perfect function and reliable operation has been developed, which provides the technical guarantee for the reliable operation of the high-voltage power distribution unit.
