摘要
10～35 kV金属封闭开关柜局部放电是导致绝缘损坏事故发生的主要原因,主要介绍引起开关柜局部放电的原因,应用开关柜局部放电检测仪,采用TEV法和时间差法,对开关柜内局部放电进行检测定位。使用结果证明:局部放电TEV检测方法和时间差定位方法,对开关柜局放缺陷的检测是有效的。
The PD of the10kV～35kV Metal-enclosed switchgear is the main reason for the accident that the insulation is damaged.This paper mainly introduces the reason for the PD of the switchgear.It uses the Switchgear Partial Discharge Detection Instrument and adopts the TEV methods and time difference methods to apply and study the Detection and Location Technology of the PD.The results show that the TEV method and time difference method is effective to detect the defect of the PD of the switchgear.
