由连云港化工高等专科学校、中国矿业大学和兖州矿业 (集团 )公司鲍店煤矿共同研制的集放式低压电网绝缘在线监测系统 ,最近已经通过了专家的技术鉴定。统计资料表明 ,矿山井下电网的电气故障 70 %以上是漏电故障 ,现场一般都是采取利用漏电保护装置的方法来解决 ,而井下中性点 The on-line low-voltage power grid insulation on-line monitoring system jointly developed by Lianyungang Chemical Engineering College, China University of Mining and Yanzhou Mining (Group) Company BaoDian Coal Mine has recently passed the expert’s technical appraisal. Statistics show that more than 70% of the electrical faults in the mine underground power grid are leakage faults. The scene is usually solved by using the leakage protection device, while the underground neutral point
