Background technique

With the development of the electric power industry, the reliability of power consumption and high-quality service are becoming more and more important. The proportion of live work in electric power production is increasing day by day, especially in emergency repairs and replacement and maintenance of power equipment. The use of live work can effectively reduce the Necessary power outage time, improve the reliability of power consumption, and ensure the power consumption of people's lives. However, due to the natural aging of electrical equipment and the influence of irresistible external forces, lightning arresters and dropout fuses are often faulty or damaged in daily work, so the team needs to perform daily maintenance and replace the equipment. However, the operation process of replacing lightning arresters and dropout fuses is cumbersome, and insulation measures must be set in place. In order to ensure personal safety, the drain wires connected to the main wires must be removed. the

In the past work process, when replacing the arrester and drop-out fuse, it is necessary to remove the drain wire connected to the main line, and then check and replace the arrester and drop-out fuse. In the process of operation, there are dangerous factors such as insufficient safety distance, and the operation steps are cumbersome, time-consuming and labor-intensive, which greatly endangers personal safety and makes it difficult to replace lightning arresters and drop-out fuses. There are several reasons: 1. Operators Utilizing the insulated arm truck to work up and down between the operating point and the main conductor not only increases the work intensity but also repeats the operation, which may easily cause damage to the main conductor and the drain wire. 2. Due to the special terrain conditions and the height of the working point itself has reached the maximum load rate, plus the length of the drainage line, the bucket arm truck is blocked and cannot complete the work. 3. Due to the narrow working space, secondary accidents may be caused between phase-to-phase (or line-to-ground) when extracting the drainage line. Therefore, how to effectively solve the problem of replacing lightning arresters and dropout fuses will greatly improve work efficiency. the
