Problems solved by technology

The reason why there are few studies in this area is that the study of this phenomenon requires the measurement of the surface charge of the insulating part. During the measurement, a probe needs to be moved on the surface of the insulating part and kept at a certain distance. In general, the actual insulating part The surface is a curved surface with a special shape, and the normal working environment is SF at an absolute pressure of 0.5MPa 6 gas, which brings great inconvenience to the measurement and control of the surface charge

Abstract

The invention relates to a four-dimensional self-adaptive insulation piece surface charge measuring device, which belongs to the technical field of the high-voltage device and the electron. The measuring device comprises a measuring probe, a probe control mechanism, a rotation disc, a camera, a power source, a controller infrared distance meter and the like. A distance signal is received by the infrared distance meter, the distance and the angle between the probe and the measured surface are automatically adjusted through a plurality of motors, the probe is maintained to be vertical to the surface, and the distance between the probe and the measured surface is constant, so the measurement of the surface charge of the insulation piece is realized. The measuring device can be arranged inside a sealing cavity which can bear the air pressure, measures the surface charge of the insulation piece in the high-air-pressure environment, realizes two translation motions and rotations of the probe, is applicable to the measurement of the insulation pieces with different shapes, and has high space resolution ratio.

Description

technical field [0001] The invention relates to a four-dimensional self-adaptive surface charge measuring device of an insulating part, which belongs to the technical field of high-voltage equipment and electronics. Background technique [0002] Gas-insulated equipment is widely used in power systems, such as gas-insulated switches (GIS) and gas-insulated lines (GIL). Compared with traditional open-type power distribution devices, gas-insulated equipment has many advantages, the most important ones are operation stability, high reliability, no insulation aging problem, small size, small footprint, and no external environment influence , simple maintenance, long maintenance cycle, quick installation, low operating costs and no electromagnetic interference, etc., so it has been valued by the power sector and has been widely used in AC systems. At present, my country is speeding up the construction of DC UHV transmission lines, and there is an urgent need to apply such equipme...
