采用地面供电模式的有轨电车供电系统电路设计与应用

Circuit design and application of tram power supply system for ground power supply mode

基于有轨电车接触网供电设计,结合地面供电装置的技术特点,提出了有轨电车地面供电系统电路设计方案。采用了大功率电子开关电路及微机控制系统,实现地面供电模式下的变电所双边供电和系统安全保护,满足多台有轨电车在一个供电区间内运行要求。

Based on the design of tram catenary power supply and combined with the technical characteristics of the ground power supply device, a circuit design scheme of the tram ground power supply system is proposed. High-power electronic switch circuit and microcomputer control system are adopted to realize the bilateral power supply and system safety protection of the substation under the ground power supply mode,which can meet the operation requirements of more than a tram in a power supply interval.
