摘要
从电击保护观点出发,对几种典型的漏电保护装置的运行性能进行了分析,提出从电网漏电电流中分离出触电电流,用以控制保护器动作的方法,并阐述了基于这种方法的信号分离动作型全自动触电漏电保护器的机理、性能和测试方法。
From the point of view of protection against electric shock,the principles and functions of some typical protective devices are analyzed.A new automatic oper- ating protective device based on the idea that the electric shock current which is separated from the total leakage current of the electric network can be used to con- trol the operation of protective device is developed.The principle,function and test method of this protective device are all described.
