[0002] At present, the common connection types between insulator strings and conductors of transmission lines with voltage levels of 35kV to 220kV are straight single string, straight double string, tension double string (the hardware connecting the crossarm of the insulator and the conductor is usually divided into triangular connecting plate and square connecting plate, and the thickness of the hardware varies). The conductors are divided into single conductor, double split conductor and other types.

[0003] Insulators may produce zero values ​​or explode during operation. At this time, the damaged insulators need to be replaced. Since there are various types of insulators and the various forms of insulator and wire connections encountered in actual work, there are generally multiple methods to carry out maintenance work, involving a large number of tools, and the following problems are prone to occur: ① To replace each type of insulator, you need to choose a corresponding set of tools, which is time-consuming and labor-intensive, and there is a risk of missing tools; ② The thickness and size of the hardware of some old lines are different, and there are practical problems such as the inability to match the new fixtures; the hardware of the crossarms and conductors of some old line insulators are usually connected by triangular connecting plates and square connecting plates. Due to the different thickness of the hardware, the "big knife card" in the existing maintenance method cannot be matched and applied; ③ If the appropriate tools are re-equipped for each type of line, the capital investment will increase.
