Specifically, the upper end of the insulating frame 1 is a single arm 101 capable of opening and closing at 180 °, and since the end of the tubular insulating member 30 uses a voltage-sharing shielding device and the middle part is provided with a flange, the closed frame cannot enter the end of the tubular insulating member 30, and therefore, the tubular insulating member 30 is in the insulating frame 1 by controlling the opening and closing of the single arm 101.
Specifically, the synchronous belt 11 and the open belt pressing plate are engaged through the toothed plate, and are tightly locked with the base plate 10 on the lower side of the insulating frame 1 through a screw passing through a mounting hole of the toothed plate, so as to achieve a fixing effect. The servo motor 12, the speed reducer 13 and the synchronous belt pulley 14 form a transmission system, the speed reducer 13 is matched with the servo motor 12 to reach a preset speed, and the synchronous belt pulley 14 drives the synchronous belt 11 to move together.
Referring to fig. 6, in the normal live-line operation process of the tubular insulating member 30, the device is placed on a lifting platform, the accommodating space in the middle of the insulating frame 1 corresponds to the center of the tubular insulating member 30, and the tubular insulating member 30 is arranged in the insulating frame 1 in a penetrating manner. Since the aluminum alloy support 17 is far enough away from the tubular insulator 30, the electric field distribution around the tubular insulator 30 is not changed, and thus the surface charge behavior of the tubular insulator 30 is not affected. The probe adjusting cylinder 3 is used for adjusting the distance between the charge probe 2 and the surface of the tubular insulating member 30, so that the device can be suitable for measuring the surface charge of the tubular insulating member 30 with different diameters. After the tubular insulating member 30 is continuously charged under the direct-current voltage, the insulating frame 1 moves on the guide rail 15, and through the set parameters of the moving speed, the stroke, the interval residence time, the movement times and the like, the insulating frame 1 moves according to the set program, 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 insulating member 30 is realized.
The device can effectively measure the distribution condition of the space charge on the surface of the tubular insulating part from four directions, and provides test basis for obtaining the accumulation and distribution mode of the space charge on the tubular insulating part and excavating space charge behavior characteristics and influence factors; meanwhile, the measurement of the space charge on the surface of the tubular insulating part with different types and sizes is realized.
