The invention discloses an overvoltage protection device, which relates to the technical field of charging piles and comprises an electricity control mechanism and a fusing mechanism. The electricity control mechanism is provided with a shell, a rotary knob, a rotating rod, a conductive column, a fixed disc, an electricity passing disc and a rotating rod. By rotating a conductive column in the electricity control mechanism to drive a rotating rod, the turn-off of a conductive sheet on the rotating rod and an electricity passing disc is controlled, the rotating rod is attracted under the action of an electromagnet which generates magnetic force after being electrified, the continuous electrifying process is ensured, the rechargeable operation is completed, and finally, after the voltage is too high and a fuse wire in the fusing mechanism is fused, the electromagnet is de-energized to disappear magnetism to trigger the effect of the bias elastic piece, so that the rotating rod is reset, the electricity passing disc is de-energized, automatic switching-off is achieved, and the situation that when parts are replaced and a charging plug connected to the charging pile is further connected, current influences possibly exist, and the life health of workers is endangered is avoided.
本发明公开了一种过压保护装置,涉及充电桩技术领域,包括:控电机构与熔断机构。所述控电机构具有:壳体、旋钮、转杆、导电柱、固定盘、过电盘、旋转杆。本发明通过旋转控电机构中的导电柱驱动旋转杆方式,以实现控制旋转杆上导电片与过电盘的关断,并在通电产生磁力的电磁铁作用下吸引住旋转杆,保障持续通电过程,完成可充电操作,最后在电压过大,熔断机构中的熔断丝被熔断后,通过电磁铁失电消退磁性触发偏置弹件的作用,使得旋转杆复位,从而使得过电盘失电,实现自动断闸,避免更换零件时和还连接在充电桩上的充电插头可能存在的电流影响,危害工作人员的生命健康。
