Problems solved by technology

[0003] 1. The distance between some insulator string umbrella skirts and umbrella skirts is relatively small, and it is difficult to wipe them by hand;
[0004] 2. Some suspension insulator umbrellas have deep grooves, and a lot of dirt often accumulates in the grooves of insulator umbrellas, which is difficult to wipe clean by hand;
[0005] 3. During the process of wiping the insulator, the dirt on the surface of the insulator is easy to adhere to the hands, arms and clothes, resulting in incomplete sampling of the dirt on the insulator, which will bring errors to the subsequent measurement of the pollution degree of the insulator surface

Embodiment 1

[0041] like figure 1 As shown, an artificial sampling device for insulator contamination includes a sampling cloth 1, a sampling rod 2 and a rubber band 3, the sampling rod 2 is composed of a spherical end 201 and a handle 202, and the sampling cloth 1 is wrapped around the spherical end 201 of the sampling rod, The tail of the sampling cloth 1 is fastened on the sampling rod 2 by the rubber band 3; the sampling cloth 1 is fixed on the sampling rod 2, and the handle 202 of the sampling rod is held in hand, so that the sampling cloth 1 wrapped by the spherical end 201 of the sampling rod contacts the insulator surface, wipe the insulator.

[0042] like image 3 As shown, the handle 202 of the sampling stick has a groove 203 around it, and the tail end of the sampling cloth 1 is fixed at the groove 203 of the sampling stick through the rubber band 3 . The sampling rod 2 has a total length of 235 mm, wherein the handle 202 is 160 mm long, the diameter of the handle 202 is 15 mm...

Embodiment 2

[0049] This embodiment is improved on the basis of the first embodiment above. The spherical end and the handle of the sampling rod are made of wood material. The spherical end and the handle of the sampling rod are integrally formed, and the sampling rod has a long service life. Can be used repeatedly for a long time.

Embodiment 3

[0051] This embodiment is limited on the basis of the above embodiments. The rubber band is made of rubber material, has excellent wear resistance, good elasticity, and can be used repeatedly for a long time.

[0052] It can be seen from the foregoing description that the present invention has achieved the following technical effects:

[0053] 1. There is a groove on the handle of the sampling rod, and the tail of the sampling cloth is fastened to the groove of the handle of the sampling rod by a rubber band, so that the sampling cloth can be firmly fixed on the sampling rod.

[0054] 2. The spherical end and handle of the sampling rod are made of wood, which has a long service life and a high reuse rate.

[0055] 3. The rubber band is made of rubber material, which has excellent wear resistance and good elasticity, and can be used repeatedly for a long time.

[0056]4. Using the device and its sampling method can carry out thorough and complete sampling of insulator pollutio...

Abstract

The invention discloses a manual sampling device for insulator contaminants and a sampling method of the manual sampling device. The manual sampling device comprises sampling cloth, a sampling bar and a fixing element, wherein the sampling bar comprises a ball-shaped end and a handle, the ball-shaped end of the sampling bar is wrapped with the sampling cloth, and the tail part of the sampling cloth is tightly locked on the sampling bar through the fixing element. According to the manual sampling device for the insulator contaminants and the sampling method of the manual sampling device, the contaminants on the surface of an insulator can be sampled thoroughly and completely, so that accuracy of insulator contaminant sampling and accuracy of insulator contamination degree measurement are improved.

Description

technical field [0001] The invention relates to an artificial sampling device for insulator pollution and a sampling method thereof. Background technique [0002] With the rapid development of social economy, the industry has also developed rapidly, and the environmental pollution in some areas has become very serious. The damage caused by the flashover accident of the external insulation of the power transmission and transformation equipment in the power system caused by pollution is becoming more and more serious. As one of the important components of the external insulation equipment of the power system, the degree of pollution accumulation on the surface of the insulator has an important impact on the operating conditions of the transmission line. At present, my country mainly uses the equivalent salt density (ESDD) and the equivalent dust density (NSDD) to characterize the pollution degree of the insulator surface. For many years, the sampling method for contamination ...
