6) residual current annunciator
剩余电流报警器
1.
There are some disadvantages existing in the actual residual current annunciator—when somebody gets an electric shock, before shake off the electric source, the person is in danger of high-voltage far from the human safety voltage.
目前不间断电源漏电保护中采用的剩余电流报警器存在以下不足:当人触电后,在摆脱电源之前,人一直处在危险电压(远大于人的安全电压)触电过程中。
