为了在采矿工业中保证电气安全,采用漏电电容电流的补偿装置,以降低通过人身的电流。在电压低于660伏时宜采用这种方法。当电压为1140伏时,这个办法的效果就不够了。这就需要研制短路器,其作用原理是人所共知的保护接地方法——用小电阻分路人体,在这种情况下。不是正常不带电的元件接地,而是人所触及的被保护电网的故障相接地。研制这个装置的问题是研制确定人 To ensure electrical safety in the mining industry, a compensation device for the leakage current is used to reduce the current through the body. This method should be used when the voltage is below 660 volts. When the voltage is 1140 volts, the effect of this solution is not enough. This requires the development of a short-circuit device, the principle of which is known as the protective earthing method - with a small resistance shunting the human body, in this case. Not normally uncharged components grounded, but people are touched by the protection of the power grid grounding. The problem of developing this device is to develop a definite person
