Abstract

Cable termination is a weak point in an underground cable system. The transient earth voltage (TEV) method is an effective and nonintrusive method for estimating the insulation condition of cable termination. However, the practical application of TEV detection is mainly focused on switchgears, generators, and transformers with a flat and conductive shell. A flexible sensor array based on the TEV method is presented for online partial discharge (OLPD) monitoring of the cable termination. Each sensing element is designed with a dual-capacitor structure made of flexible polymer material to obtain better and more stable sensitivity. Based on the electromagnetic (EM) wave propagation theory, the partial discharge (PD) propagation model in the cable termination is built to analyze and verify the rationality and validity of the sensor unit. Some influencing factors are discussed regarding the response characteristics of sensors. Finally, the performance of the sensor array is verified by simulations and experiments. Besides, an OLPD monitoring system is introduced. The monitoring system is composed of the on-site monitoring device and the remote monitoring host. The two parts of the system exchange the data through wireless networks using a wireless communication module. The experiment results show that the monitoring device could supply the PD condition monitoring demand for cable termination.

摘要

电缆终端是地下电缆系统中的一个薄弱环节。暂态地电压（TEV）方法是一种用于评估电缆终端绝缘状况的有效且非侵入性的方法。然而，TEV检测的实际应用主要集中在具有平坦导电外壳的开关设备、发电机和变压器上。本文提出了一种基于TEV方法的柔性传感器阵列，用于电缆终端的在线局部放电（OLPD）监测。每个传感元件采用柔性聚合物材料制成的双电容结构设计，以获得更好、更稳定的灵敏度。基于电磁波传播理论，建立了电缆终端局部放电（PD）传播模型，以分析和验证传感器单元的合理性和有效性。讨论了一些影响传感器响应特性的因素。最后，通过仿真和实验验证了传感器阵列的性能。此外，还介绍了一种OLPD监测系统。该监测系统由现场监测装置和远程监测主机组成。系统的这两部分通过无线网络使用无线通信模块进行数据交换。实验结果表明，该监测装置能够满足电缆终端局部放电状况监测的需求。
