Description

Special cleaning device for insulator pollution

technical field

The invention relates to a special cleaning device for insulator pollution. the

Background technique

The salt density test of suspension insulators of transmission lines is an important content of anti-pollution flashover of power grid, and it is a test method to obtain typical saturated salt density (or saturation pollution degree) of anti-pollution flashover parameters of insulators in power grid operation. The surface of the insulator that has been in operation for a certain period of time is affected by the surrounding environment. The porcelain part of the insulator and the surface of the composite insulator material are affected by their own electric field and adsorption. Dirt will adhere to the surface of the insulator and the iron parts. When the environment is dirty, the same pollution as the source of the pollution will form on the surface of the insulator. When the insulator is polluted to a certain extent, it will form a current channel on the surface of the insulator along with the operating voltage and humidity. The leakage ratio of the insulator at this time is equal to the ratio of the operating voltage to the creepage distance of the insulator. In order to ensure the safe operation of power grid lines and formulate corresponding anti-pollution flashover prevention measures, it is necessary to test the salt density test of transmission line suspension insulators to master the test methods and results of saturated salt density (or saturated pollution degree); A new parameter for the grid pollution level division, that is, the pollution level is determined by the saturation equivalent salt density and gray density. Its actual salt density value and gray density value are used to formulate preventive measures for anti-pollution flashover. the

During the artificial pollution test, the pollution degree of the surface of the insulator is expressed by salt density and gray density (solid layer method). The salt density is used for the artificial pollution test, and the equivalent salt density is used to describe the natural pollution of the on-site insulator. Contamination test of ordinary disc insulators, proposed cleaning methods for different salts, different dust density and uneven distribution of pollution on the upper and lower surfaces of insulators; reference cap and pin insulator: used to measure and describe the degree of pollution on site insulators. IEC60815 stipulates that it is a standard disc-shaped suspension insulator for lines (disk diameter 255mm, structural height 146mm, creepage distance 300mm); the product models in my country are XP-70 and XP-160, LXP-70 and LXP-160. XWP2-70 and XWP2-160 are also used as reference insulators. the

The sampling range is the shortest distance or the sum of the shortest distances between the metal fittings at both ends of the insulating surface of the insulator. Concrete and any other non-insulating surfaces between end fittings do not count towards creepage. the

Sampling pollution The ratio of the total amount of sodium chloride coated on the insulating surface of the insulator of the test sample to the insulating surface area during the artificial pollution test, mg/cm2. the

Equivalent attached salt density (ESDD) of sampling pollution: the electrical conductivity is equal to the ratio of the total amount of sodium chloride of the natural polluted water-soluble matter on the insulating surface of the on-site insulator after dissolution to the insulating surface area, mg/cm2. the

Insoluble Density (NSDD): The ratio of the total amount of non-water-soluble substances on the insulating surface to the insulating surface area, mg/cm2. the

Site Pollution Degree (SPS): Refer to the maximum equivalent salt density and dust density obtained by referring to the continuous pollution on the surface of the insulator for 3 to 5 years (pollution sampling must be carried out at the end of the pollution season). the

Use desalted distilled water (conductivity less than 10μs/cm) as the water for cleaning the insulator under test, regardless of the influence of the conductivity of the cleaning water on the measurement

Now insulators have to be transported for a long distance during the cleaning process. Due to the uneven handling, handling, stroking and cleaning of the insulators, the influence of the contamination of the iron parts of the insulators, and the use of cleaning plates in the original method, the pollution distribution equipment is large and the gray density accuracy is reduced. This leads to inaccuracy in insulator salt tightness testing. the

When in use, the cleaner is transported to the site where the insulator needs to be cleaned, and the removed insulator is directly placed on the bracket, without long-distance transportation, so as to avoid affecting the accuracy of the salt density test. The insulator is placed at the opening of the bracket. The fittings at one end are in contact with the groove, and the fittings at the other end are in contact with the pulley, so as to ensure stable placement.

Using the rotary sampling method, there is no need to manually hold the hardware part, which prevents additional pollutants from falling into the collection tray. Since the cleaning is carried out on the rack, the danger of finger corrosion by pollution sources is avoided. The use of this device can prevent the dirt attached to the insulator from falling off during the handling process of the insulator under test, and improve the accuracy of measuring the equivalent salt density and ash density of the insulator.
