摘要

10 kV开关柜作为中国配网系统中非常重要的设备

其运行的可靠性直接关系到供电可靠性。开关柜内的绝缘缺陷或劣化、接触不良等都会成为其安全运行的隐患

而这些隐患在设备正常运行的情况下又很难发现。为解决上述问题

笔者介绍了基于暂态对地电压（TEV）、超声波（AE）、超高频（UHF）原理的联合局部放电检测方法。该方法可以为评估开关柜运行状态和检修工作提供丰富的数据依据

全面保障10 kV开关柜的安全运行。

Abstract

10 kV switchgears are important equipment in Chinese power distribution networks.The defects such as insulation degradation and poor contacts in a 10 kV switchgear

which are difficult to be detected while the switchgear is operating normally

may harm its safe operation.Therefore

this paper proposes a joint partial discharge detection method based on the principles of transient earth voltage（TEV）

ultrasonic（AE）

and ultra high frequency（UHF）.The method can offer sufficient data for status evaluation and maintenance of the switchgear to guarantee safe operation.
