Since the aluminum alloy brackets 17 are sufficiently far from the tubular insulator 30, the electric field distribution around the tubular insulator 30 is not changed, so that the surface charge behavior of the tubular insulator 30 is not affected. The probe adjusting cylinder 3 plays a role in adjusting the distance between the charge probe 2 and the surface of the tubular insulator 30 so that the device can be suitable for measuring the surface charges of the tubular insulators 30 with different diameters. When the continuous charging of the tubular insulator 30 under the direct-current voltage is finished, the insulating frame 1 moves on the guide rail 15, and the insulating frame 1 moves according to a set program through the set parameters such as the moving speed, the travel, the interval residence time, the movement times and the like, so that the measurement requirement of the charge probe 2 is met, and the reproduction of the accumulation condition of the charges on the surface of the tubular insulator 30 is realized.
It can be seen that the device can effectively measure the distribution condition of space charges on the surface of the tubular insulating piece from four directions at the same time, and provides test basis for obtaining accumulation and distribution modes of the space charges on the tubular insulating piece, and excavating space charge behavior characteristics and influence factors; at the same time, space charge measurements of the surface of tubular insulators of different types and sizes are achieved.
