In the construction of the power grid and equipment maintenance, various safety measures must be implemented to prevent minor personal injuries and above-mentioned accidents. The State Grid Corporation of China stipulates that when working on a scaffold without scaffolding or without railings and the height exceeds 1.5 meters, safety belts should be used or other reliable safety measures should be taken. There are also regulations: the hook or rope of the seat belt should be hung on a strong and firm component, or on a steel wire rope specially used for hanging the seat belt, and should be hung high and low. It is forbidden to hang on moving or unstable objects [such as isolating switch (knife switch) support insulators, CVT insulators, busbar post insulators, lightning arrester post insulators, etc.].

The height exceeds 1.5 meters, and the safety belt should be used, but the isolating switch (knife switch) support insulator, CVT insulator, circuit breaker insulator, busbar post insulator, and arrester post insulator cannot be used. Hanging the safety belt on the insulator is a serious violation of regulations. When the insulator breaks, it will cause a high-altitude fall and personal safety accident; 2. The violation of the safety belt hanging on the insulator repeatedly occurs during on-site supervision by safety supervisors; 3. Fighting The arm truck cannot enter the work site, and the bucket arm truck cannot be used; 4. The electrical safety distance is not easy to meet the requirements when setting up the landing operation platform, and the erection time is long, which requires high costs; 5. There is a greater risk of falling during the climbing process; 6. The cost of purchasing special equipment is relatively high; 7. It has been unable to solve the violations of substation electrical maintenance at high altitudes for many years.
