Description

Technical Field

[0001] The invention relates to the technical field of mobile substations, in particular to a cable winch device for 220kV temporary connection and quick connection. Background Art

[0002] The installation of cable terminal accessories is a key process in the construction of power cable projects. The quality of its installation is related to whether the cable line can operate safely and stably for a long time. Therefore, the quality requirements for construction skills, processes, environment and accessory manufacturing are relatively high. At the same time, the installation process of cable terminal accessories is complicated and cumbersome. Before making cable accessories, the cable should be heated and straightened to eliminate the mechanical stress caused by the twisting of the cable during cable laying and the dimensional changes caused by the thermal shrinkage of the insulation after the cable is put into operation. The cable connection time is relatively long, and it is impossible to quickly and safely connect with the user end. This means that the on-site construction period is long, which is not conducive to the needs of emergency rescue and fault repair to shorten the power outage time. It is necessary to develop a fast connection device. Summary of the invention
