Problems solved by technology

This measurement method has the following deficiencies: ① It is very inconvenient to pick and carry the insulator, and the dirt on the insulator will be wiped off if you are not careful during the process of picking and handling the insulator, making the measurement result lower than the actual value; ② Pollution There is a deviation in the collection method: the current common practice is to wear thick rubber gloves to clean the insulator and collect the dirt. A little carelessness will wash off the dirt on the adjacent insulator sheets, resulting in a deviation between the measurement results and the actual results; if using After wiping the insulator with a sponge or absorbent cotton, the ash on the sponge or absorbent cotton is difficult to clean, and it will also have a great impact on the experimental results

Embodiment Construction

[0031] The method of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0032] The on-site sampling method for insulator pollution of the present invention comprises the following steps:

[0033] Step 1. Prepare the insulator pollution sampling kit, such as figure 1 As shown, including sampling cloth, wetting agent, sampling gloves, collection bag and sample box, wherein the sampling cloth is non-woven fabric, for 300 ml The conductivity value of deionized water is not affected by more than 5 μs / cm ; The wetting agent has a conductivity of less than 5 μs / cm deionized water; the sampling gloves are plastic gloves; as a specific embodiment, the sample box 1.5 is made of engineering plastics, which is not deformed under heavy pressure, and the sample box has two layers, the upper layer is a sample placement area, and the bottom layer is an isolation The desiccant is placed in the isolation layer, wh...

Abstract

The invention discloses a method for on-site sampling and pollution degree measurement of insulator pollution. The method adopts a sampling cloth to directly wipe the pollution on the surface of the insulator to be tested without taking off the insulator, and completes the collection of pollution on the surface of the insulator to be tested. According to GB / T16434 or Q / GDW152-2006 measure the salt density and ash density value of the dirt on the sampling cloth, that is to get the salt density and ash density value of the surface of the insulator to be tested. The method of the invention does not need to take off the insulator, and has the advantages of convenient on-site measurement, small sampling workload, accurate measurement data and the like.

Description

technical field [0001] The invention belongs to the technical field of power system monitoring, and in particular relates to a method for on-site sampling of insulator pollution and measurement of pollution degree. Background technique [0002] Equivalent salt density and ash density are important parameters to determine the pollution degree of transmission and transformation substation equipment. When the transmission and transformation substation equipment is heavily polluted, the probability of pollution flashover and tripping of transmission and transformation substation equipment will be relatively high. Therefore, when the transmission and transformation substation equipment is heavily polluted, It must be cleaned. The current domestic measurement method is to take the insulator off the transmission line and bring it back to the laboratory for measurement. This measurement method has the following deficiencies: ① It is very inconvenient to pick and carry the insulator...
