The invention relates to the field of rail transit, in particular to a high-voltage device for a double-current system rail transit vehicle, which comprises a pantograph, a high-voltage box and a high-voltage cable, and is characterized in that the pantograph comprises an underframe assembly, a pantograph lifting mechanism, an insulator, a lower arm assembly, a lower guide rod, an upper arm assembly, an upper guide rod and a pantograph head assembly; the insulator is mounted at the bottom of the underframe assembly; the pantograph lifting mechanism is installed on the underframe assembly, the lower arm assembly is connected between the upper arm assembly and the pantograph lifting mechanism, and the pantograph head assembly is installed at the end, away from the lower arm assembly, of the upper arm assembly; the pantograph lifting mechanism comprises an air bag and a steel wire rope, the lower arm assembly comprises a lower arm, and the steel wire rope is connected between the lower arm assembly and the air bag. Compared with the prior art, the high-voltage device can be used under a double-current working condition, and the electrical safety is ensured. The high-voltage box comprises a high-voltage box body, a vacuum circuit breaker and an alternating-current and direct-current voltage transformer. The technical problem that the vacuum circuit breaker cannot be arranged due to insufficient space of the double-current system rail transit vehicle is mainly solved.

    本发明涉及轨道交通领域,具体涉及一种用于双流制轨道交通车辆的高压装置,包括受电弓、高压箱和高压线缆,受电弓包括底架组装、升弓机构、绝缘子、下臂组装、下导杆、上臂组装、上导杆和弓头组装;绝缘子安装在底架组装的底部上;升弓机构安装在底架组装上,下臂组装连接在上臂组装和升弓机构之间,弓头组装安装在上臂组装远离下臂组装的端部上;升弓机构包括气囊和钢丝绳,下臂组装包括下臂,钢丝绳连接在下臂组装和气囊之间。本方案相比现有技术,高压装置能够在双流制的工况下使用,保证了电气安全。高压箱包括高压箱体、真空断路器和交直流电压互感器,主要解决了双流制轨道交通车辆因空间不足导致的真空断路器无法布置的技术难题。
