在评价电击伤人的保护时,在确定意外接触带电部件通过人体的电流时,在研究电气装置引起的某些电伤事故时,以及在分析露天矿电气设备存在的电气危险性时,都必须确定接地短路电流值。问题在于根据不同因素来确定短路电流形成的规律。至今,还认为短路电流是由于露天矿配电网路各单元形成的对地电容产生的。
In assessing the protection of persons injured by electric shock, it is necessary to study certain electrical injuries caused by electrical installations and to analyze the electrical hazards existing in the electrical equipment of open-pit mines in determining the accidental contact of live parts with live parts through the human body Determine the ground short-circuit current value. The problem is to determine the law of the formation of short-circuit current according to different factors. So far, it is also believed that the short-circuit current is generated due to the capacitance of the ground formed by each unit of the open-circuit mine distribution network.
