摘要
通过分析直流电流对人体的效应,计算不同直流电流路径对应的安全电流阈值。提出了直流电击防护用RCD的最大分断时间参考值,同时对建筑物直流配电中不同的用电场所提出了相应的电击防护方案。
The effect of the DC current through the human body is analyzed, and the safety current threshold value of different DC current path is calculated. The maximum breaking time reference value of RCD for DC electric shock protection is proposed. At the same time, the corresponding electric shock protection scheme is proposed for the different electric field in the DC power distribution of the building.
