摘要:
通过案例分析探讨了两种高压电缆局部放电带电检测技术的应用。针对传统带电检测技术仅仅只是反映短时间内电缆及附件状态的不足,首先在线路B上安装高压电缆局放重症监护系统,通过3 d不间断监测排除了一起中间接头的疑似放电缺陷,确认局放重症监护技术是运行电缆局放检测的重要补充手段。接着介绍了电缆终端局部放电在线监测系统,以及在国内使用就发现线路C的B相电缆终端存在疑似局部放电信号的案例,通过停电解剖,验证了局放信号存在的事实,从而确认终端局放监测技术发现电缆终端局放缺陷的有效性。
Abstract:
This paper discusses the application of two kinds of discharged detection technology for partial discharge(PD)of high voltage cable through case analysis. In view of the problem that the traditional technologies just reflect the state of the cables and accessories in a short period,firstly the PD intensive care system is installed in the high voltage cable B; through three days’ continuous monitoring,the joint in the middle of the suspected discharge with defects is ruled out. It can be concluded that the PD intensive care technology is an important supplementary means of running the discharge test of the cable. Then,cable terminal PD on-line monitoring systems are introduced. The domestic use of line C’B phase cable terminals discovers the suspected cases of PD signals. Electricity through dissection verify the fact that there is a fire signal,thus confirming discharge monitoring terminal technology can prove the effectiveness of the defect cable terminal station.
