中文摘要:
      本文介绍一套专用于电缆线路局部放电带电检测的多功能便携式局部放电测试系统装置的应用开发。首先简要介绍电缆线路及其附件的局部放电的发生机理,由此确定检测传感器的检测方法和安装位置,其中包括高频脉冲电流法、特高频电磁波法、超声波法、暂态地电波法,高频天线法的接法形态,并在此基础上开发了能够灵活配用8种局放传感器的高功能局放带电检测系统。本文通过两个现场成功案例的介绍,展示说明该此测试仪是一种很适合于电缆带电检测,方便携带、功能齐全的测试仪器。此测试仪不仅能够对4个相同的传感器或4个不同种类传感器的信号进行有效的同步采集,实时自动分析判断,还可局放定位,为提高检测效率、及时发现电缆及其附件中的绝缘缺陷提供有力的的支持。
英文摘要:
      It is introduced that a kind of portable PD measurement system has been developed for power cable circuit. Based on the causes of PD produced in cable and its accessories various PD sensors such as HFCT, HUF, AE and TEV have also been developed for site PD detection application. Therefore, this new type PDM equipment is designed and made to be matched with eight kinds of PD sensors, so it can perform multiple measurement functions in which signals from four same PD sensors or four different PD sensors can be detected, analyzed and judged synchronously. This paper also gives two successful on-site PD measurement examples to show that this kind of high-end PDM equipment can provide high efficient PD measurement and PD localization for safe operation and maintenance of cable circuit.
