Problems solved by technology

[0005] 1) Sampling with a paper knife has high sampling requirements; the size of the sample is uneven; due to the radian on the surface of the insulator, the thickness is incomplete; after sampling, the sampling part needs to be repainted
[0006] 2) Due to the short schedule of power outage work, most of the on-site coatings are now powered on when the surface is not cured, making it impossible to sample the coating thickness
[0007] 3) Due to the requirements of power supply reliability, some equipment currently adopts technical measures to apply anti-pollution flashover coating with electricity, so it also makes it impossible to sample the coating thickness
[0008] Due to the above deficiencies, it brings great difficulties and defects to the on-site acceptance work, and brings hidden dangers to the safe operation of the equipment.

Abstract

The invention relates to an electrified measuring and sampling tool for coating thickness of an anti-pollution flashover coating for electrical equipment. The electrified measuring and sampling tool comprises an insulating rod, a safety limiting mark and a sampling device, wherein the safety limiting mark is fixedly arranged on the insulating rod at one hand-held side; the sampling device is arranged at one end of the insulating rod. The tool can be electrified for sampling, and is safe and reliable, so that the sampling work for measuring the coating thickness of the anti-pollution flashover coating by electrifying can be completed better, and safety operation of the electrical equipment can be ensured.

Description

technical field [0001] The invention belongs to the field of power auxiliary tools, in particular to a sampling tool for electrification measurement of the coating thickness of an anti-pollution flashover coating for power equipment. Background technique [0002] The anti-pollution flashover coating for the external insulation of the power system is an important technical measure to effectively prevent the pollution flashover of the external insulation of the power system power transmission and transformation equipment. The coating should be recoated every 5 to 10 years. effects are closely related. The testing standard DL / T627-2012 requires that the thickness of the coating is generally not less than 0.3mm, and the specific implementation of each unit is also different. [0003] The current measurement method is the slice method to measure the coating thickness of anti-pollution flashover (RTV). The sampling method is: "The sample should be randomly selected on the upper a...
