为了减少触电事故,保证人身安全,许多工程技术人员开展了大量的研究工作。然而有些研究只提供了被动性的预防措施,没有设法解决造成触电的根本原因,致使触电事故仍然继续发生。据统计,低压单相触电死亡事故,占触电死亡事故的80%以上。因此,要改变这个状况,必须寻找避免单相触电 In order to reduce electric shock accidents and ensure personal safety, many engineers and technicians have conducted a great deal of research work. However, some studies only provided passive preventive measures and did not try to solve the root cause of electric shock, so that electric shock accidents still continued to occur. According to statistics, single-phase low-voltage electric shock deaths, accounting for more than 80% of electric shock deaths. Therefore, to change this situation, we must find ways to avoid single-phase electric shock
