Problems solved by technology

[0003] Under natural conditions, the surface of insulators is very uniformly polluted. In the artificial pollution tests carried out in the laboratory, artificial smearing was used in the past. The insulator surface is not uniformly polluted, which affects the accurate extraction of discharge characteristics and the determination of pollution levels in subsequent insulator discharge tests. correct judgment

Abstract

The invention relates to a device for spraying contamination onto the surface of an insulator uniformly. The device comprises a rack, a stepping motor (8), a driving wheel (2), a driven wheel (16), a loading plate (6) and a contamination sprayer (15). The stepping motor (8) is fixed to the rack. The driving wheel (2) is arranged on the output shaft of the stepping motor (8). The driving wheel (2) is in transmission connection with the driven wheel (16) through a belt. A shaft body (14) is disposed on the axis of the driven wheel (16) and is rotatably connected with the rack. The loading plate (6) is arranged on the shaft body (14) for fixing the insulator (7). The contamination sprayer (15) sprays the surface of the insulator (7) with contamination during the rotation of the insulator (7). Compared with the prior art, the device has advantages of small friction, strong bearing capacity, safe and stable running, precise and controllable rotation speed, simple operation, convenient disassembly and transportation and the like.

Description

technical field [0001] The invention belongs to the technical field of discharge characteristics of insulator surface pollution and artificial pollution discharge test of insulators, and in particular relates to a technology for evenly coating the surface of insulators in the artificial pollution discharge test of insulators. Background technique [0002] Pollution discharge and pollution flashover on the surface of insulators seriously threaten the safe and stable operation of the power grid. Detecting the pollution state of the insulator surface in advance and determining the pollution cleaning plan can reduce the occurrence rate of power grid pollution flashover, improve the safety and reliability of the power grid, and reduce national economic losses. At present, the methods for identifying the pollution state of the insulator surface in the charged state, such as leakage current method, optical pulse detection method, multi-light source image method, etc., all need to o...
