当前,在电气化水平迅速提高的形势下,要防止触电事故增多,必须在电气安全管理、标准和产品质量等方面相应采取措施。 低压电网接地保护系统的内容,主要是指1千伏以下的配电变压器中性点是否接地,中性线与保护地线是否分开,用电设备外露的金属壳体是接地线还是接中性线,以及与此 At present, under the circumstance of rapidly increasing electrification level, to prevent an increase in electric shock accidents, measures must be taken in areas such as electrical safety management, standards and product quality. The content of the low-voltage power system grounding protection system mainly refers to whether the neutral point of the distribution transformer below 1 kV is grounded or not, whether the neutral line and the protective earth line are separated, whether the exposed metal housing of the electric equipment is the earth line or the neutral line Line, and with this
