基于 OWTS 技术的电缆局放检测应用分析

摘要

论述了电力电缆由于其具有供电可靠的特性，并且满足城市规划的要求，正在得到广泛应用。指出为了保证电缆的安全可靠运行既要重视故障检测手段，也要从源头上把关，针对隐藏缺陷进行检测，OWTS （振荡波局放测试系统）作为一种方便有效的电缆检测新技术目前正不断推广。对于 OWTS 检测技术的原理进行了介绍，并通过两个现场案例分析验证了其有效性。阐明了 OWTS 检测技术的推广应用将对电网的安全可靠产生巨大的经济和社会效益。%With the characteristics such as reliable power supply,and great significance for the city’s beauty,power cable is widely applied. In order to guarantee the safe and reliable operation of the cable,we should not only attach great importance to the fault detection method,but also not ignore hidden defects. OWTS as a convenient and effective technology for cable testing is continuously popularized. This article introduces the principle of OWTS detection technology,the effectiveness of which is verified through the analysis of two cases. It is illustrated that OWTS detection technology will produce great economic and social benefits for power grid’s safe and reliable operation.
