在TN和TT系统中,"断零"后由于各相负载值大小不等,导致负载中性点O'点的电位产生位移,使各相负载电压的大小不等。文章根据O'点电位分别位于"一点"、"六线"、"六区"、"三边"的位置,简析各相负载电压的变化规律及其危害。
在TN和TT繫統中,"斷零"後由于各相負載值大小不等,導緻負載中性點O'點的電位產生位移,使各相負載電壓的大小不等。文章根據O'點電位分彆位于"一點"、"六線"、"六區"、"三邊"的位置,簡析各相負載電壓的變化規律及其危害。

In the TN and TT system,the potential of the neutral O′ shifts and this leads to that each phase voltage of load is not equal,because the each phase load is not equal after the neutral line is broken.This paper analyses the variation of the each phase voltage of load and its damage when the potential of the neutral O′ is at "one point","six line","six zone" and "three side" respectively.
