[0002] As a special accessory of a lightning arrester, the disconnector is used in series with the lightning arrester. Its purpose is that when the lightning arrester has an abnormality and fails, the disconnector is made to act by using the power frequency short-circuit current, so that the grounding end of the disconnector is automatically disconnected, the lightning arrester exits from operation, the accident is prevented from further expanding, and a visible disconnection mark is given to the faulty lightning arrester for the air-to-air, so as to facilitate maintenance personnel to timely find the fault point for maintenance and replacement. When the lightning arrester is in a normal working state, the disconnector does not act and presents a low impedance (compared with the lightning arrester), does not affect the original working state of the system and the protection characteristics of the lightning arrester, ensures uninterrupted power supply, and enables the lightning arrester to truly meet the "maintenance-free" use requirements.

[0003] At present, most manufacturers, in order to facilitate the disassembly and assembly between the disconnector and the lightning arrester to improve the maintenance effect, make the installation method between the disconnector and the lightning arrester be that the arc-shaped fixing hoop and the splicing hoop are inserted into each other, and then after the splicing hoop and the arc-shaped fixing hoop are spliced, they are fixed by fixing bolts, so as to realize the rapid installation of the mounting bracket and the main body of the lightning arrester; although the design of the above structure can achieve the purpose of being convenient for disassembly and assembly, due to the installation environment being outdoors, in the case of long-term use, the fixing bolts are prone to rusting, resulting in the splicing hoop and the arc-shaped fixing hoop being unable to be separated, thus affecting the maintenance work of the disconnector and the lightning arrester, and the practicability is poor.

[0025] In this embodiment, the connecting device 2 includes a connecting block 21, a connecting component 23, and a conductive component 22. The connecting block 21 is assembled in the fixing position 6. A first threaded rod 3 is fixedly connected to the bottom of the connecting block 21. An installation cavity 211 is provided on the top surface of the connecting block 21. A conductive component 22 is assembled in the installation cavity 211. A connecting component 23 is assembled on the top of the connecting block 21, and the top of the conductive component 22 abuts against the bottom of the connecting component 23, so as to achieve the connection function.

[0026] In this embodiment, the conductive component 22 includes a conductive elastic sheet 221, a guiding column 222 and a conductive connection block 223.
