1 电流对人体的影响1.1 感知电流(感受电流)用手握带电导体,在直流情况下能感知手心轻轻发热;在交流情况下,因神经受到刺激而感到轻微刺痛.感知电流平均值1.lmA.1.2 摆脱电流(人触电后能自行摆脱的电流值)男人:9mA、女人:6mA国际电工委员会IEC标准:10mA·s.1.3 安全电流:在特定时间内,通过人体的电流,对人体未构成生命危险的电流值IEC标准:3OmA·s.1.4 室颤电流(人触电死亡的临界值)1OOmA·0.5s 400mA·0.15s 1OmA·12Omin1.5 安全电压:触电死亡的直接原因,不是由于电压,而是由于电流缘故,但在制订保护措施时,还应考虑电压这一因素.
1 current impact on the human body 1.1 sensing current (feel the current) with a hand-charged conductor, in the case of DC can feel the palms gently heat; in the case of AC, due to nerve stimulation and feel a slight tingling. The average perceived current 1 .lmA.1.2 Get rid of the current (people can get rid of the current value after electrocution) Man: 9mA, Woman: 6mA International Electrotechnical Commission IEC standard: 10mA · s.1.3 Safe Current: In a specific period of time, Not constitute a life-threatening current value IEC standard: 3OmA · s.1.4 VF current (human death threshold) 1OOmA · 0.5s 400mA · 0.15s 1OmA · 12Omin1.5 Safe voltage: the direct cause of electric shock is not due to Voltage, but because of the current, but in the development of protective measures, should also consider the voltage factor.
