Problems solved by technology
[0002] At present, in order to ensure the personal safety of the workers, it is necessary to conduct electrical inspections on the high-voltage lines and related equipment when performing maintenance on the medium and high-voltage lines of the distribution network. At this time, it is necessary to use a high-voltage electroscope. Live electrification is one of the necessary safety tools for electric workers, but the current technical considerations are not perfect, and it has the following disadvantages: Due to the high terrain on the plateau and no shelter, the wind is strong, when testing the high-voltage lines on the plateau, due to The high-voltage electroscope is blown by the strong wind, and the operator is prone to swing when holding the electroscope at high altitude, making it difficult for the electroscope part to slowly touch the high-altitude overhead wire, and it is easy to be blown by the wind and then quickly get close to the erection cable and then the Collision, the detection head is broken from time to time, shortening the service life of the electroscope

The invention discloses a high-voltage electroscope for a plateau distribution network based on a wind pressure effect. The high-voltage electroscope comprises a hand-held insulating grip, a waterproof sleeve, a telescopic frame, a ceramic insulating tube, and a main detecting body. On the basis of combination of a wind pressure buffer structure, a blade adjusting device and an electroscope structure, when a cable is built at a plateau area for electroscope processing, the electroscope approaches the built cable slowly, so that a phenomenon that the electroscope approaches the built cable quickly due to the strong wind effect of the plateau in working and thus collides the cable to break the detection head of the electroscope is avoided and thus the service life of the electroscope is prolonged effectively. Meanwhile, the detection head is fixed with the built cable well and is prevented from sliding by the wind force, so that the accuracy of the electroscope detection is improved.
