地铁能量吸收装置开关电气互锁设计

Design of Switch Electrical Interlock for Metro Electrical Energy Absorption Device

介绍地铁能量吸收装置主回路的组成及工作原理,指出功率开关误动作产生的危害。根据控制系统逻辑互锁要求,完成了控制系统的设计,并提出一种新型双重电气互锁设计思想,给出设计方法,确保在误动作情况下设备上电工作安全,保证电网和机车的正常运行。

The composition and working principle of the main circuit in the subway energy absorption device were introduced,and the harm caused by the misoperation of the power switch was discussed.According to the requirements of the logic interlocking of the control system,the design of the control system was completed.A novel dual electrical interlocking design idea was proposed.The design method was given.The safety of the equipment was on power under the misoperation as well as the normal operation of the power grid and locomotive were guaranteed.
