Technical Field

[0002] Insulator zero measurement is to detect whether the insulator is low value or zero value. When the insulator string is in operation, the insulator with zero potential difference at both ends is called zero value insulator; in layman's terms, once the zero value phenomenon occurs, it means that the insulator has been broken down, the resistance value is zero, and it can no longer play an insulating role, which will seriously affect the safe operation of electricity. Therefore, it is necessary to regularly detect the insulators in operation to prevent zero value insulation in advance. The publication number CN 115219859A proposes an insulator zero value detection device, including an unmanned aerial vehicle body, a private service rotating platform is provided in the carrying frame of the unmanned aerial vehicle body, and a mounting base is fixedly installed on the turntable of the private service rotating platform. A pitch plate is installed on the mounting base through a pitch adjustment mechanism, and a telescopic plate is installed on the pitch plate through a telescopic adjustment mechanism, and a real-time image return mechanism is also provided on the pitch plate, and a rotating plate is installed on the telescopic plate through a rotation adjustment mechanism, and two detection probes are installed on the rotating plate through a discharge gap adjustment mechanism, and the detection ends of the two detection probes have a spacing that matches the width of the insulator.

[0003] In the above technical solution, for some businesses, using drones to detect the zero value of insulators is relatively expensive, and in harsh environments, drones cannot work normally, thus affecting user detection; therefore, we propose a device for detecting the zero value of insulators to solve this problem.
