Special rust removal device for electrical test

The invention relates to a derusting device special for an electrical test. The derusting device comprises a tripod and an insulating rod detachably arranged on the tripod, and the top of the insulating rod is at least provided with one of a polishing machine and an electric paint spraying gun, and a wireless control device and at least one camera which are matched with the polishing machine and the electric paint spraying gun to work. Operation can be completed on the ground, rust removal and paint removal can be carried out on expected positions of equipment with different heights, high-place operation is avoided, the high falling risk is avoided, the problem of test abnormity caused by high-voltage end corrosion or thick paint of a voltage transformer and the like in a transformer substation can be rapidly solved, the test efficiency is improved, the maintenance progress is accelerated, normal electrical test is guaranteed, and the maintenance cost is reduced. And high-place operation can be avoided, and t
