摘要
在现有电缆绝缘在线监测技术分析研究的基础上,主要通过实验室实验和仿真研究,验证了低频信号叠加法用于煤矿井下电网电缆绝缘监测是可行的。该技术研究应用于煤矿,对预防和减少煤矿井下供电事故的发生,提高煤矿供电的安全可靠性,促进煤矿的安全生产具有重要意义。
Based on the analysis and research of the existing cable insulation online monitoring technology, and mainly through laboratory experiment and simulation research, it is proved that it is feasible to use low frequency signal superposition method to monitor the insulation of power network in coal mine. This technology is applied to coal mine. To prevent and reduce the occurrence of coal mine underground power supply accident. Improve the safety and reliability of coal mine power supply. Promoting coal mine safety production is of great significance.
