A modular charging pile convenient to maintain disclosed by the present invention comprises a charging pile, an electric box and a plurality of charging modules embedded in the electric box, one side of each charging module is provided with a rectification electric plate used for being electrically connected with an external power supply, and the rectification electric plates are fixedly installed on one side of the interior of the electric box. And an inert gas tank for inert gas is fixedly mounted on one side of the rectifying electric plate. During normal work, the electromagnet generates a magnetic field to enable the magnetorheological fluid to keep certain viscosity, the stability of the conducting strip and the piston plate is ensured, and a current path is maintained; by designing an electromagnet, a Venturi tube, a conducting strip and other devices, when the charging module breaks down and the current is sharply increased, a metal diaphragm of the conducting strip is fused, the electromagnet loses excitation, a first spring piece pushes a piston plate to extrude magnetorheological fluid to wrap a clamping groove to cut off electric connection, meanwhile, deionized water is treated to loosen a buckle, fault expansion is prevented, and the system safety is improved; and the damage to the charging module and other equipment caused by short circuit is reduced.
本发明公开了一种方便维保的模块化充电桩,包括充电桩、电箱和嵌合安装于电箱内的多个充电模块,所述充电模块的一侧均设有用于与外部电源电连接的整流电板,且整流电板均固定安装于电箱的内部一侧,所述整流电板的一侧固定安装有惰性气体的惰性气罐。在正常工作时,电磁铁产生磁场使磁流变液保持一定黏度,确保导电片和活塞板稳定,维持电流通路;通过设计电磁铁、文丘里管和导电片等装置,当充电模块故障电流急剧增大时,导电片金属膜片熔断,电磁铁失磁,弹簧件一推动活塞板挤压磁流变液包覆卡槽切断电连接,同时处理去离子水使卡扣松开,防止故障扩大,提升了系统安全性,减少了因短路对充电模块及其他设备造成的损害。
