人们通常把电击电流分为感知电流、反应电流、摆脱电流和心室纤颤电流等经验证明,通过人体的电流不超过10 mA,触电人可以摆脱电源,不会造成事故;通过人体的电流超过10 mA时,人就有生命危险,当通过人体的电流达到100 mA时人体在很短时间内就会心跳停止一般情况下,只有不高于36 V的电压才是安全的,原来通过导体的电流可以用下列公式计算:
一般情况下,人的双手间的电阻是1000~5000欧姆(Ω),当人的手湿润时,电阻会变为200~800Ω,因此;当人体触摸到36 V的电压时,通过人手的电流会达45~180 mA
通常情况下36v是安全电压,
可是有的人手上的茧子很厚 手还干燥,可以通过触摸220v的电压,电视上演的。无论怎么的通过他心脏的电流不会太大,大了谁都见阎王
36V,36v称为安全电压,凡是高于36v的电压,对于人体就构成威胁了。
