通过对地铁列车AC 400 V供电系统常用接地方式的比较,推荐了一种新型AC 400 V供电系统接地方式,并结合具体地铁项目详细阐述了此接地方式的特点、原理及相关部件的选择方法。此种接地方式以最低成本满足了地铁列车供电系统的供电连续性及检修维护及时性的要求。
By comparing the commonly used grounding methods of AC 400 V power supply system for subway trains, a new type of grounding system for AC 400 V power supply system was proposed. The characteristics, principle and selection of relevant components of the grounding system were described in detail in connection with the subway project. This grounding method to meet the minimum cost of the subway train power supply continuity of power supply and maintenance of timely maintenance requirements.
