Technical Field

[0002] As a device that supports and fixes bare carrier fluid and insulates bare conductors from the ground, the history of insulators can be traced back to the early days of the electric power industry. With the continuous advancement of electric power technology, the types, shapes and materials of insulators have been greatly enriched and developed to meet the needs of different voltage levels, different environmental conditions and use occasions. With the intelligent development of power systems, the performance requirements for insulators are getting higher and higher, such as the development of new insulating materials with excellent electrical and mechanical properties to meet the needs of higher voltage, large capacity and extreme working conditions. With the advancement of manufacturing technology, the production process of insulators has been continuously optimized, which has significantly improved the performance and quality of insulators. At the same time, the quality control and detection methods of insulators are also constantly improving to ensure the safe operation of insulators in power systems.

[0003] When insulators need to be repaired or replaced, the operation becomes very difficult. Since they cannot be easily disassembled and installed, the maintenance work may be time-consuming and labor-intensive, and may even require additional tools or equipment, increasing the complexity and cost of the operation and seriously affecting work efficiency. Especially in the case of emergency repairs or replacements, the power supply interruption time may be prolonged, affecting the user's power experience. Due to the complexity of the operation, the risk of operational errors may increase, which may lead to safety accidents. In addition, if the damaged insulators cannot be replaced in time, it may also pose a threat to the stable operation of the power system. Insulators may be more easily damaged when facing bird strikes, tree branch scratches or other mechanical stresses, affecting their structural integrity and electrical performance. Bird droppings may also fall on the insulators. If not cleaned in time, it will affect the conductivity of the insulators, reduce power transmission, and cause resource loss. Utility Model Content
