摘要
分析了直流电流对人体的效应,提出了正极DC190 V可作为LED庭院灯配电电压等级。计算结果表明,该电压等级具有与AC220 V相当的供电能力,同时用电安全性得到了较大的提高。
The effect of the DC current through the human body is discussed in this article. The positive DC190 V as LED garden lamp distribution voltage level is proposed. The calculation results show that the power supply capacity of the voltage level is equivalent to AC220 V, and the electrical safety could be improved greatly.
