Abstract

This article considers the effects of wire breakage in networks with an insulated neutral, as well as issues related to detecting the location of such damage. The need to use means and techniques for rapidly localizing line sections with wire breakage is revealed and justified. The analysis conducted allows proposing a technique for detecting line sections with phase wire breakage in branched networks with an insulated neutral. This technique is based on analyzing voltage readings from the meters installed in the low-voltage part of transformer substations connected to the damaged network. The implementation of this technique requires using software that is integrable with available electronic supervisory control resources without installing additional equipment because it is possible to use electric counters with data transmitters installed everywhere at transformer substations as voltage meters.

具有断线的电线断面检测技术

摘要

本文考虑了带有绝缘中性线的网络中断线的影响,以及与检测此类损坏的位置有关的问题。揭示并证明了需要使用手段和技术来快速定位带有断线的线段。进行的分析允许提出一种技术,用于在具有绝缘中性线的分支网络中检测相线断裂的线段。该技术基于分析安装在与损坏的网络相连的变电站的低压部分中的电表的电压读数。
