煤矿电缆暂态故障行波信号传输特性的研究

Study of Transmission Characteristics of Transient Fault Traveling Wave in Mine Cable

煤矿电缆是煤矿生产的动力源泉,线路发生故障后,快速准确地找到故障点并加以修复,是煤矿微机保护工作者孜孜以求的目的。目前行波测距在煤矿的应用还是空白,由于煤矿对供电性能的特殊要求,因此有必要开展这方面的应用研究。本文对影响行波测距的各个因素进行了仿真,并进行了详细地分析。

Coal mine cables are the power source of coal mine production, when fault occurs, quickly and accurately find the fault point and repair the fault point, which is the purpose of microprocessor-based protection are pursuing. At current, there is still a blank of traveling wave fault location in the coal mine, because of the special requirements of power supply in mine coal, it is necessary to carry out the applied research in the mine coal area. This paper simulate various factors which affect the ranging of...
