用有效盐密作为表征污秽度的新方法
New Method to Describe Contamination Degree of Insulators by Effective Equivalent Salt Deposit Density
摘要
Abstract
The effective equivalent salt deposit density (EESDD) can represent the contaminated degree of power transmission and transformation equipment and can make up for the defect that the equivalent salt deposit density(ESDD) method has little correlation with the pollution flashover voltage.We introduced new measurement equipment of EESDD and studied the influences of the probe size,water consumption,and salt composition on the measurement of the EESDD through a series of artificial contamination tests.A probe with the size of 5.13 mm and 1.00 mm and water consumption of 0.02 mL/cm2 was chosen.Then,the concrete method of EESDD was presented.At last,the method of EESDD was applied in the actual operation of power transmission and transformation equipment to compare the ESDD and EESDD of the surface of the insulators in different areas.Moreover,the regional characteristics of contamination were discussed to provide a basis for the further promotion of the EESDD.A conclusion can be drawn that EESDD is a good characterization of the parameters of the contamination degree and a quite good supplement for ESDD.关键词
