Problems solved by technology
At the same time, the installation process of the cable terminal accessories is complicated and cumbersome. Before the cable accessories are made, the cables should be heated and straightened to eliminate the mechanical stress in the cables caused by the twisting of the cables and the dimensional changes caused by the insulation heat shrinkage after the cables are put into operation. The cable connection time is relatively It is also relatively long, and it is impossible to quickly and safely realize the docking with the user end, so the on-site construction period is longer, which is not conducive to emergency rescue and fault repair to shorten the power outage time, and it is necessary to develop a quick connection device

The invention discloses a 220kV temporary contact rapid connection cable winch device which comprises a semitrailer, wherein three cable winches are rotatably connected to the semitrailer, a cable is wound around the cable winches, one end of the cable is connected to a second cable terminal, the end, which is away from the second cable terminal, of the cable is connected to a first cable terminal, the first cable terminal is installed on a first cable terminal fixing device, and a second cable terminal fixing device is fixedly installed on the semitrailer. By the adoption of the structural arrangement, the cable connection operation is more flexible, convenient and effective, the cable, the first cable terminal and the second cable terminal are installed in a factory in advance, an overall transportation mode is adopted, and the cable is released by the cable winch on site, so that the work of mounting the first cable terminal and the second cable terminal on site is reduced, the cable winch can conveniently take up and pay off, and the workload of on-site construction is reduced. The device is suitable for mobile substations.
Description
technical field [0001] The invention relates to the technical field of mobile substations, in particular to a 220kV temporary contact quick connection cable winch device. Background technique [0002] The installation of cable terminal accessories is a key process in the construction of power cable engineering. The quality of its installation is related to whether the cable line can run safely and stably for a long time. Therefore, the quality requirements for construction skills, craftsmanship, environment and accessory manufacturing are relatively high. At the same time, the installation process of the cable terminal accessories is complicated and cumbersome. Before the cable accessories are made, the cables should be heated and straightened to eliminate the mechanical stress in the cables caused by the twisting of the cables and the dimensional changes caused by the insulation heat shrinkage after the cables are put into operation. The cable connection time is relatively ...
