Abstract

The invention discloses an insulator rotating mechanism and an insulator surface charge measurement experimental device. The insulator rotating mechanism comprises a rotating disc bearing, a worm gear, a worm and a first driving mechanism, wherein the inner ring of the rotating disc bearing is connected with the worm gear; the axis of the rotating disc bearing is parallel to that of the worm; the worm gear is connected with an insulator; the worm is meshed with the worm gear; the first driving mechanism is connected with the worm. By adopting the insulator rotating mechanism and the insulator surface charge measurement experimental device, control of the insulator rotating for 360 degrees can be achieved, the surface of the insulator is scanned and measured with the combination of a probe scanning measurement mechanism, the movement control of the probe scanning measurement mechanism can be simplified, and novel experimental means can be provided for insulator surface measurement experimental study.

Description

technical field [0001] The invention relates to the research field of internal insulation of equipment in a power system, in particular to an experimental device for measuring the surface charge of an insulator. Background technique [0002] Gas-insulated electrical equipment is a widely used device in power systems. Compared with traditional open-type power distribution equipment, it has the advantages of reliable operation, small footprint, and no external environment influence. In the gas-insulated electrical equipment of the power system, a large number of insulating parts such as basin-type support insulators are required. During the operation of gas-insulated electrical equipment, especially under the action of DC voltage, a large amount of charge is easy to accumulate on the surface of the supporting insulator inside the gas-insulated electrical equipment, resulting in a decrease in the flashover characteristics along the surface. Therefore, it is necessary to study ...
