摘要
随着国家电力工业的迅速发展,电网规模不断扩大,电压等级不断提高,对电气设备的运行也提出了更高要求。局部放电作为高压电气设备绝缘劣化的重要征兆,其有效检测与故障诊断对保障设备安全运行具有重要意义。现通过高压电气试验中局部放电的几种主要检测方法:超声波检测法、化学检测法、脉冲电流法以及超高频检测法,探讨了这些方法的故障诊断效能。通过对比分析,旨在为高压电气设备的绝缘监测与故障诊断提供理论依据和技术支持。
With the rapid development of national power industry,the scale of the power grid has been continuously expanding and the voltage level has been constantly increasing,so there are higher requirements for the operation of electrical equipment.The effective detection and fault diagnosis of partial discharge,as an important sign of insulation deterioration in high-voltage electrical equipment,have a great significance to ensure the safe operation of equipment.This paper discusses the fault diagnosis efficacy of several main methods of detecting partial discharge in high-voltage electrical tests including ultrasonic detection method,chemical detection method,pulse current detection method and ultra-high frequency detection method.Based on the comparative analysis,it aims to provide the theoretical basis and technical support for the insulation monitoring and fault diagnosis of high-voltage electrical equipment.
