The invention discloses a cable take-up and pay-off device. The device comprises a working box; the transmission mechanism is arranged in the working box and is used for winding and unwinding a cable; two ends of the cable are provided with quick-plug interfaces, one end is used for being connected with a power grid, and the other end is used for being connected with a charging pile. According to the scheme, the charging pile main cabinet does not need to be reopened for wiring when the charging pile is replaced, the charging pile does not need to be carried, and safety accidents possibly occurring in the test process are greatly reduced. In addition, as the three-phase cable is thick and difficult to wind, and if the three-phase cable is stretched and retracted by adopting a mode similar to a wire roller, when a close charging pile is connected, as most of the cable is still wound on the wire roller, a large electromagnetic field and accumulated heat can be generated after the charging pile is electrified, and safety accidents are easily caused. According to the scheme, negative effects caused by cable winding can be avoided.
本申请公开了一种线缆收放装置,包括:工作箱;设置于所述工作箱内的传动机构,用于对线缆进行收放;所述线缆的两端设置有快插接口,一端用于与电网连接,另一端用于与充电桩连接。通过本发明方案无需在更换充电桩时重新打开充电桩主机柜进行接线,也无需搬运充电桩,大幅降低了试验过程中可能发生的安全事故。此外由于三项线缆较粗难以缠绕,且如果采用类似于线滚模式实现伸长和缩回,在连接较近的充电桩时,由于大部分线缆仍在线滚上缠绕,在通电后会产生较大的电磁场及积热,容易引发安全事故,本申请方案可避免线缆缠绕引发的负面影响。
