摘要

带电清洗剂在绝缘子带电状态下进行清洗

其温度特性及与绝缘子表面污秽混合后的电气性能值得关注。为此

开展了带电清洗剂温度特性及混合污秽后电气性能试验

测试了4种市售不同型号带电清洗剂的介质损耗因数、相对介电常数、体积电阻率、击穿电压及其温度特性

得到了混合不同污秽质量分数下的体积电阻和击穿电压。测试结果表明

随着温度的升高

介质损耗因数增大

同样温度下1号和3号带电清洗剂介质损耗因数较大

50℃时远超标准规定值。4种清洗剂的相对介电常数随着温度升高而降低。4种纯净带电清洗剂的体积电阻率在20℃时较大

均随着温度的升高而降低。当带电清洗剂掺杂质量分数为0.5%的污秽时

其体积电阻率将下降一个数量级

但均>1.0×1012?·cm;当掺杂质量分数为0.5%

.5%的污秽时

其体积电阻率变化不明显。当掺杂质量分数为0.1%

.5%的污秽时

带电清洗剂的工频击穿电压下降较明显。当掺杂质量分数为1%

%的污秽时

工频击穿电压没有明显下降。

Abstract

Live-working washing agent is used to remove the insulators’ contamination away under the insulators in charge state.Temperature characteristics of live-working washing agents and whether the contamination will influence the electrical characteristics of live-working washing agents are problems which should be paid more attention to.Hence

we experimentally tested the electrical performances of live-working washing agents under the condition of adding different quality fractions of the contamination

measured the pure state

dielectric loss term

relative dielectric constant

volume resistivity

and power frequency breakdown voltage

and compared and obtained electrical performance and their temperature chara

cteristics of four kinds of live-working washing agents.In addition

volume resistivity and power frequency breakdown voltage under different amount of contamination were obtained.The test results show that the dielectric loss factor will increase with the increase of temperature.The dielectric loss factor of live-working washing agents No.1 and No.3 is relatively larger

the values at 50 ℃ exceed the limit value of standard.The relative dielectric constant of four samples will decrease with the increase of temperature.And the volume resistivity of pure state is larger at 20 ℃

and will decrease with the increase of temperature.The volume resistivity will decrease by an order of magnitude with mass fraction 0.5% mixed contamination

but still more than 1.0×1012 ?·cm.While the mass fraction is 0.5%

.5%

and the volume resistivity subtly changes.Moreover

the power frequency breakdown voltage with 0.1%

.5% mass fraction drops more noticeably compared with purity agent

and insignificantly drops with 1%

% mass fraction.
