When a transmission line fails, a fault finder is usually used to quickly identify where the fault occurs. A Chinese utility model patent, authorization announcement number "CN211263732U", discloses a cable fault finder, including a buckle, a box cover, a transformer chamber, a control box, a pulse chamber, an insulator, a discharge rod, a connecting wire, and a fixed buckle belt. The utility model uses the insulator as a grounding protector for the discharge rod. After opening the connection between the fixed buckle belt and the wall hole of the support plate, the movable shaft uses the rod connecting slot plate as a support body, and the two ends are screwed together to fix the screw joints.

[0003] The above technical solution is to spread the bottom layer of the support plate on the ground after being turned outward along the opening wall of the rod connecting slot plate, and the discharge rod can be directly placed vertically on the surface of the composite plastic layer. The layer has the advantages of good insulation and low thermal conductivity. It is mainly used for the ground protection operation of the discharge rod, which can effectively avoid the damage and failure of the discharge component directly rubbing against the ground. It has the protective functions of insulation, storage and organization of electrical appliances. In order to cope with emergencies, it is necessary to seize the time to detect and repair problems. The above new type is restricted by buckles. When it needs to be used, it is necessary to first unlock the buckles and then rotate the box cover to open the device. For emergency repair work, it is still a waste of time. Utility Model Content

[0039] A temperature sensor 5 is fixedly installed inside the housing 2 .

[0040] A button spring 11 is fixedly connected to the surface of the button 12 , and one end of the button spring 11 away from the button 12 is fixedly connected to the surface of the housing 2 .

[0041] The surface of the cover body 1 is fixedly connected to a limiting column 13 , and a sliding groove 14 is formed on the surface of the limiting column 13 .

[0042] A small ball 16 is slidably connected inside the sliding groove 14, and the surface of the small ball 16 contacts the inside of the limiting groove 17, and the surface of the small ball 16 contacts the surface of the button body 10;

[0043] A handle 3 is fixedly connected to the surface of the housing 2 .

[0046] When encountering a circuit failure, if you want to quickly open the shell 2, press the button 12 to drive the button body 10 to move. The movement of the button body 10 drives the small ball 16 to move to the inside of the sliding groove 14. The movement of the small ball 16 drives the small ball spring 15 to be compressed. At the same time, the second magnet 9 and the first magnet 4 have opposite magnetism, and the magnetism drives the cover body 1 to rotate.

[0047] When the shell 2 needs to be closed, the cover body 1 is rotated by external force to drive the limit column 13 to move, the movement of the limit column 13 drives the sliding groove 14 to move, and the movement of the sliding groove 14 drives the small ball 16 to move until it coincides with the position of the limit groove 17.

[0048] When the interior of the shell 2 needs to be cooled, the compressor 8 is started by the battery 19 to cool the liquid inside the circulation pipe 7 and drive the liquid inside the circulation pipe 7 to move. The movement of the liquid inside the circulation pipe 7 takes away the heat of the air inside the shell 2.

[0049] By pressing the button 12 in the quick start device, the ball 16 is disengaged from the inside of the limit groove 17, and the second magnet 9 and the first magnet 4 rebound and drive 1 to quickly open the fault finding device. The device can be quickly opened by pressing the button 12. Compared with the general buckle-type fault finding device, this new type can save time when opening, save time for repairing faults, and thus improve the repair efficiency.

[0050] When performing emergency repairs to check for faults, the inspection device needs to be run for a certain period of time. In order to avoid excessive internal temperature due to long-term operation, a start-up compressor 8 is set to drive the liquid inside the circulation pipe 7 to flow and cool down, thereby ensuring that the interior of the shell 2 can operate stably at a reasonable temperature.

[0051] Working principle: When encountering a circuit failure, if you want to quickly open the shell 2, press the button 12 to drive the button body 10 to move. The movement of the button body 10 drives the small ball 16 to move to the inside of the sliding groove 14. The movement of the small ball 16 drives the small ball spring 15 to be compressed. At the same time, the second magnet 9 and the first magnet 4 have opposite magnetism, and the magnetism drives the cover body 1 to rotate.

[0052] When the shell 2 needs to be closed, the cover body 1 is rotated by external force to drive the limit column 13 to move, the movement of the limit column 13 drives the sliding groove 14 to move, and the movement of the sliding groove 14 drives the small ball 16 to move until it coincides with the position of the limit groove 17, and the small ball spring 15 resets and drives the small ball 16 to enter the inside of the limit groove 17.

[0053] The compressor 8 is started by the storage battery 19 to cool the liquid inside the circulation pipe 7 and drive the liquid inside the circulation pipe 7 to move. The movement of the liquid inside the circulation pipe 7 takes away the heat of the air inside the shell 2.
