Safety measures; 18.1.8 stipulates that the hooks or ropes of safety belts should be hung on strong and firm components, or on steel wire ropes specially used for hanging safety belts, and should be hung high and low. On solid objects (such as disconnector support insulators, CVT insulators, busbar post insulators, lightning arrester post insulators, etc.). Maintenance personnel must wear seat belts when performing maintenance work, but the above-mentioned equipment does not meet the specified position. It is used to fix the seat belts and tied to porcelain insulators or foundation beams. It is an illegal operation and there is a great potential safety hazard. , Bring inconvenience to the maintenance work of the equipment. At the same time, after the porcelain insulators are painted with anti-pollution flashover paint, maintenance personnel cannot climb on the insulators with their feet, making it difficult to carry out equipment maintenance work, which seriously affects the reliability of safe operation of the equipment.
