| 摘 要： | 通过对三相四线系统零线运行故障的分析,发现三相四线中的零线因故断路后,在三相负载不对称时,则会产生变压器中性点位移,致使三相电压不平衡,即有的相电压过高,可能烧毁电器设备,有的相电压过低,使电器设备无法正常使用。为了防止此类故障的发生,通过试实验研究,提出了具体可行的预防措施,以供实际工作中参考.

| Abstract: | By analyzing null line running failure in the three-phase four-wire system, it was found that the null line running failure will cause displacement of the transformer＇s neutral point and results in voltage unbalance. Over-high voltage will burn electrical equipment, and low voltage will make equipment fail to work. In order to prevent the occurrence of the fail- ure, feasible precautions were put forward through the experimental research. |
