摘　　要：在低压配电网中主要采用剩余电流保护装置来实现触电保护,但是现有的实际投运率并不高,运行效果不明显。针对此问题,本课题组在福建省部分地区展开调研,分析运行存在的主要问题,针对性地提出技术管理措施,同时就这方面的技术研发提出建议。In low-voltage distribution network,residual current protection ismAinly used to achieve electric shock protection.However,the actual operation rate of the existing RCD is not high,and the operation effect is not obvious.In response to this problem,the research team conducted a survey in some areas of Fujian Province,analyzed themAin problems in operation,and put forward technicalmAnagement measures in a targetedmAnner,and at the same timemAde suggestions on technology research and development in this area.

关 键 词：剩余电流保护装置 触电保护 投运率
