无线网络技术视角下井下漏电保护系统分析

Analysis of underground leakage protection system from the perspective of wireless network technology

漏电事故可引发煤矿井下电路相间短路、人身触电、矿井火灾甚至爆炸等事故,是范围广、发生率高且危害极大的煤矿井下电力系统故障。因此相关企业与单位应对煤矿设备故障进行重点监测。基于此,笔者将从煤矿配电系统三级防护网络切入,阐述以无限网络为基础的漏电保护系统以及传统选择性漏电保护系统的优势与劣势,并通过研究总线和分支线路漏电防护技术的原理、实施方案提出从软件和硬件两个方面解决漏电事故的策略。

The electric leakage accident can cause the mine underground circuit phase short circuit, personal electric shock,mine fire and even explosion and other accidents, is a wide range, high incidence and great harm of underground coal mine power system fault. Therefore, relevant enterprises and units should focus on the monitoring of coal mine equ ipment failure. Based on this, the author will from the mine level 3 protection network, power distribution system based on wireless network leakage protection system as well as the advantages and disadvantages of traditional selective leak age protection system, and through the study of bus and branch line, the principle of leakage protection technology, imp lementing scheme is put forward from two aspects of hardware and software to solve the leakage accident of strategy.
