Application of Live Detection Technology in Switch Cabinet Insulation Fault Detection

开关柜是电力系统的重要工作设备,在工作过程中,一般带有高压电荷,其内部的稳定性直接影响电力设备的安全、高效运行,而开关柜内部的绝缘系统故障直接影响设备稳定运行。采用带电检测技术对设备的电气运行数据状态进行检测,能有效保证电气数据检测的准确性,从而提高带电设备检测故障的准确率。本文针对开关柜绝缘故障引起的局部放电现象进行分析,对开关柜带电检测技术进行探讨,阐述带电检测技术的具体应用。

Switchgear is an important working equipment of power system. In the process of working, it generally has high voltage charge, its internal stability directly affects the safe and efficient operation of power equipment, and the fault of insulation system in switchgear directly affects the stable operation of equipment. The electric operation data state of the equipment can be detected by live detection technology, which can effectively ensure the accuracy of electrical data detection, so as to improve the accuracy of fault detection of live equipment. This paper analyzed the partial discharge phenomenon caused by the insulation failure of the switch cabinet, discussed the live detection technology of the switch cabinet, and expounded the specific application of the live detection technology.
