摘要:
对PBTS跨坐式单轨车辆辅助供电系统的组成、电压制式，以及辅助电源装置的设备构成和工作原理进行了分析总结。针对某海外项目，环境温度高、对单轨车辆空调系统的制冷需求较大的情况，辅助供电系统输出功率需要从PBTS跨坐式单轨车辆原有的37.5 kW增大至43 kW。为此，从辅助电源装置内使用的主要设备，对如输入电感、输入熔断器、预充电电路、输入电流传感器、智能功率模块等的可行性和适应性进行研究。研究发现，既有PBTS跨坐式单轨车辆辅助电源装置内大部分设备都能适应功率变大后的要求，三相输出滤波电感、去耦电感、输出接触器等设备则需要重新设计或选型。
Abstracts:
In this paper, the composition and voltage type of the auxiliary power supply system, the equipment structure and working principle of the auxiliary power unit for PBTS straddle monorail vehicle are analyzed and summarized. According to the higher refrigeration demands for the monorail vehicle air conditioning system which will work in an oversea project with high ambient temperature, the output power of the auxiliary supply system needs to be increased from the original 37.5 kW of PBTS straddle monorail vehicle to 43 kW. For this reason, the feasibility and adaptability of the main equipment in the auxiliary power unit are studied, including input inductance, input fuse, pre\|charge circuit, input current sensor, IPM, etc. The research result shows that most of the equipment in the auxiliary power unit of PBTS straddle monorail vehicle can meet the requirements of the increased power, but the three\|phase output filter inductance, decoupling inductance and output contactors need to be redesigned or re\|selected.
