Abstract
The invention discloses an experimental method for insulator dirt deposition. The experimental method for the insulator dirt deposition comprises the following steps: placing an insulator in a wind tunnel experiment device, starting the wind tunnel experiment device to carry out a blowing test on the insulator, placing the insulator in a fog environment, carrying out a rainfall test on the insulator, carrying out drying on the insulator, collecting dirt on the surface of the insulator, and analyzing an experimental result. The experimental method for the insulator dirt deposition is simple in setting, the experiment is carried by repeating a plurality of procedures, and the experimental result is closer to a true value. Dirt collection is more convenient and more complete. An experiment flow is standard, and the interference of human factors is eliminated.
Description
Technical field
The present invention relates to a kind of test method, be specifically related to insulator contamination test method.
Background technology
Be suspended in airborne solid or liquid particle and be deposited on insulator surface, form pollution layer.This pollution course is determined by the acting force that filthy particulate is subjected to that mainly the adhesion when also being contacted with insulator surface by filthy particulate is simultaneously determined near insulator.Often be suspended in that filthy particulate has two kinds in the air: the one, make the ultrafine dust (diameter is less than 1 μ m) of Brownian movement with gas molecule, the permanent suspension, smaller to the effect that insulator pollutes; The one, the mineral matter dust, the organic fine particles that fly up from ground, the flue dust of factory's chimney discharging, and the spittle of wave machine and sea wind are carried under one's arms and the salt solution droplet that comes, these filthy particle sizes are bigger, they are subjected to the combined action of gravity, wind pressure and electric field force near insulator, insulator surface is polluted.
When the contamination of insulator was analyzed, currently used method mainly contained, and the one, carry out site test, namely hang different insulator test products at same circuit or current conversion station, advanced certain contamination phase and analyze then, its shortcoming is the influence that is subjected to external environment, and the dispersiveness of data is bigger; The secondth, utilize the calculating that the line element method is arranged, when the analysis air flow stream is crossed insulator surface, umbellate form is to the influence of airflow field, thereby the contamination characteristic of contrast different insulative, this method is fairly simple from operating, only need to calculate to get final product, but the correctness of net result also needs to come secondary proof by test.
Summary of the invention
The object of the present invention is to provide a kind of insulator contamination test method, method is simple, is convenient to gather experimental data, and the result of test of many times contrasts mutually, draws experiment conclusion.
In order to achieve the above object, the present invention is achieved through the following technical solutions: insulator contamination test method is characterized in,
Above-mentioned method comprises following steps:
Step 1, insulator is placed in the wind tunnel test device;
Step 2, open the wind tunnel test device, to the insulator test of drying;
Step 3, insulator is placed the fog environment;
Step 4, insulator is carried out salt fog test;
Step 5, insulator is carried out drying;
Step 6, step 2, step 3, step 4 and step 5 circulation are carried out, gather the filth of insulator surface after the circulation 1 time, 2 times, 4 times;
Step 7, the filth of the insulator surface that collects is analyzed.
Also need insulator is placed in distilled water or the deionized water before being placed into insulator in the wind tunnel test device in the above-mentioned step 1, clean dunghill and carry out drying.
In the above-mentioned step 2 insulator being dried, to select wind speed for use be 4.5 m/s in test, and the air-supply time is 20 minutes, and air-supply is and with filth.
In the above-mentioned step 2 insulator dried and filthyly in the test mixed by 80% porcelain earth and 20% sodium chloride.
In the above-mentioned step 3 insulator is placed the fog environment, insulator continues 10 minutes in the fog environment.
In the above-mentioned step 4 insulator is carried out salt fog test, insulator was drenched with rain 15 minutes.
In the above-mentioned step 5 insulator is carried out drying, need dry 25 minutes of insulator.
Insulator contamination test method of the present invention compared with prior art has the following advantages: test arranges simple, and a plurality of step revision tests are more near actual value; This method is gathered filthy more convenient, more complete; The experiment process standard has been got rid of the interference of human factor.
