在三相四线制的低压电网中,变压器的中性俗称“零线”。由于“0”在绝对数上表示一无所有,因此有人忽视了零线的重要性。但往往设备或人身事故就发生在这根线上。为了防止意外事故,我们总结了如下零线三忌。一忌线路松断导线必须有足够的机械强度,并且接触点要牢固可靠。否则,就会造成以下故障:1. In the three-phase four-wire system of low-voltage power grid, the transformer neutral commonly known as “zero line ”. Since “0 ” means nothing in absolute terms, someone ignored the importance of the zero line. But often equipment or personal accident occurs on this line. In order to prevent accidents, we summarize the following zero line three bogey. Avoid lines loose wire must have sufficient mechanical strength, and the contact point to be solid and reliable. Otherwise, it will cause the following faults: 1.
