伴随着经济建设规模的日益扩大化,我国的用电量规模越来越庞大,特别是用电安全问题是值得深思的,用电安全已经纳入我国供电系统的重点行列。特别对于一些特殊作业中,比如煤矿而言,我国用电部门和劳动保护部门必须高度重视起来,必须做好井下低压电网的漏电保护工作,必须建立科学和完善的电力保护系统。首先概述了井下供电系统与漏电保护的现状,分析了井下供电中产生漏电的原因与危害,设计了井下供电系统与漏电保护系统,最后提出了相关配套措施:积极应用智能漏电保护器、建立架空线直流漏电保护装置和加强供电与漏电保护的监管。
With the expanding of economic construction scale, the scale of electricity consumption in our country is getting larger and larger. Especially the problem of electricity safety is worth pondering. Electricity safety has been put into the key ranks of our power supply system. Especially for some special operations, such as coal mines, China’s electricity sector and labor protection departments must attach great importance to it and must do a good job of underground power leakage protection of low-voltage power grids, and must establish a scientific and comprehensive power protection system. First of all, the status quo of underground power supply system and leakage protection is summarized, the causes and hazards of underground power supply leakage are analyzed, the underground power supply system and leakage protection system are designed, and the related supporting measures are put forward at last: Actively applying intelligent earth leakage protection and establishing overhead Line DC leakage protection device and strengthen the supervision of power supply and leakage protection.
