The invention relates to the technical field of electric locomotives, in particular to a pantograph lightning protection device which comprises a pantograph and a lightning protection structure connected with the pantograph, the lightning protection structure comprises a mounting base, a lightning arrester convenient to disassemble and assemble is arranged on the mounting base, the upper end of the mounting base is rotationally connected with a rotary disc, and the upper end of the rotary disc is rotationally connected with the pantograph. A driving protection structure is arranged on the rotating disc, the driving protection structure comprises a plurality of arc-shaped protection plates corresponding to the lightning arresters, a cleaning structure matched with the driving protection structure is further arranged on the rotating disc, and the cleaning structure comprises a plurality of cotton wipers corresponding to the lightning arresters. The problems that in the prior art, a pantograph is not provided with a lightning protection and overvoltage protection device, a lightning arrester is purely arranged at the bottom of the pantograph, and the service life of the lightning arrester is short are effectively solved.
本发明涉及电力机车技术领域,尤其涉及一种受电弓防雷装置,包括有受电弓和与受电弓相连接的防雷结构,所述防雷结构包括有安装底座,安装底座的上设置有便于拆卸安装的避雷器,所述安装底座的上端转动连接有转盘,转盘上设置有驱动防护结构,驱动防护结构包括有若干和避雷器相对应的弧形防护板,所述转盘上还设置有和驱动防护结构相配合的清洁结构,所述清洁结构包括有若干和避雷器相对应的棉擦,有效的解决了现有技术中受电弓并没有避雷及过电压保护装置以及单纯在受电弓底部设置避雷器,避雷器的使用寿命较短的问题。
