摘要

针对变电站用支柱瓷绝缘子的断裂

以吉林省部分252 kV隔离开关支柱瓷绝缘子作为试验样品

进行了支柱瓷绝缘子的弯曲破坏试验、扭转破坏试验、声速测量及化学成份分析等研究工作

对大量试验结果进行综合分析的基础上

得出随着声速的增加

弯曲强度、高强瓷的概率、扭转强度均呈增加的趋势;随着瓷质中铝含量的增加

弯曲强度和声速也有增加的趋势

但存在着一定的分散性;随着瓷质中钠、钾含量的增加

弯曲强度与扭转强度均略有下降趋势

但不甚明显。

Abstract

This paper presented the test for bending resistance and twisting resistance of 252 kV post insulators of ceramic material used in Jilin province substation.And try to find the relationships between bending resistance

twisting resistance

sound velocity and component of ceramic material post insulator.Based on the comprehensive analysis of a large number of test results

it is obtained that with the increase in speed of sound

the flexural strength

the probability of high-strength porcelain and torsional strength are increasing.With the increase of Al content in ceramic

there is an increasing trend in the flexural strength and speed of sound

but a certain dispersion is existing.With the increase of Na content

K content in ceramic

there is an decreasing trend in the flexural strength and torsional strength

but is not obviously.
