摘要
本文讨论TN(接零)系统中,三相四线和三相五线在其末端单相配电系统中,N线在什么条件下会发生危险电压?什么情况下N线必须与相线同时切除?
This paper is just to discuss distribution circuit of TN-system in the single-phase, including both three-phase four-wire system and three-phase five-wire system. In what situation does dangerous voltage happen with N-wire? In what situation must both N-wire and phase-wire be interrupted simullaneously?
