浅谈配电系统中保护接零和保护接地的缺陷及对策

The Defect and Countermeasure in the Power Distribution System of Zero-Connection Protection and Ground-Connection Protection

三相四线制配电系统中,保护“接零”和保护“接地”是低压配电系统中最常用的安全措施.本文分析了三相四线制系统中危及人员安全的各种因素,并提出了相应对策.

In the power distribution system of ＂three- phase- four- line＂, zero - connection protection and ground- connection protection are the most common measures for the defect in the low- pressure power distribution system. This paper analyses all kinds of factors that may endanger people＇s life in the system of ＂three - phase - four- line＂ and gives some related measures as well.
