轨道交通工程中的等电位联结及低压四极开关的使用问题

Application of Equipotential Bonding and LV 4-poles Switch in Rail Transit

从民用建筑电气设计入手分析,比较了1992年版《地下铁路设计规范》条件下轨道交通接地设计与民用建筑的不同。在2003年版《地铁设计规范》规定的条件下,轨道交通工程应实施等电位联结但不必采用低压四极开关。

Based on the analysis of the earthing design in civil architecture and in line with the Metro Design Standards adopted issued in 1992, the author holds that equipotential bonding should be provided but the LV 4 - poles switch could not be used occording to the new standard issued in 2003.
