全自动驾驶模式车辆基地牵引供电系统方案

针对全自动驾驶模式，研究车辆基地的牵引供电系统方案。根据车辆基地布局及全自动驾驶典型运营场景，提出全自动驾驶模式下牵引供电系统开关应具备遥控、遥信和不停电倒闸等功能需求。通过对各种直流开关进行分析和比选，提出一套完整的牵引供电系统改进方案。分区级采用直流负荷开关替代原手动隔离开关，就地级采用以接触器为主要元件的防误操作检修开关替换原手动检修开关，同时牵引供电系统增加与门禁和信号系统的联锁功能。介绍改进方案中所应用的直流负荷开关及防误操作检修隔离开关，具有成熟产品和技术，能够满足系统的要求。

Vehicle Depot Traction Power Supply System Based on a Fully Automatic Operation Mode

The traction power supply system of a vehicle depot is studied for a fully automatic operation mode. According to the vehicle depot layout and typical operation scene of the fully automatic operation, the switches in traction power supply system should have the functions of telecommunicating and uninterrupted power supply for switching operation. Through the analysis and comparison of different types of direct current (DC) switches, a complete set of improved traction power supply system is proposed. A DC load switch is used as as the division level equipment instead of a manual disconnecting switch. An anti-malfunction disconnecting switch is used as the local level equipment with a contactor as the main component instead of a manual overhaul switch. The interlock functions between the traction power supply system and the access control, signal system are increased. The DC load switch and the anti-malfunction disconnecting switch used in the fully automatic operation power supply system have mature products and satisfy the system requirements.
