摘要

现行标准中仅给出交流斜面法的试验条件

而未给出直流斜面法的试验方法

而试验电压是斜面法试验中的基本参数。为此

文中针对直流条件下试验电压对硅橡胶材料蚀损程度的影响展开研究。在污液流速为0.2 m L/min的条件下

使用高速摄像机、红外热像仪观察不同试验电压下硅橡胶材料表面电弧的放电现象和温度场分布

并记录不同试验电压下的泄漏电流、质量损失和最大蚀损深度。试验结果表明

随着试验电压增大

电弧弧长明显增大

累计放电时间减小

试样的质量损失和最大蚀损深度均减小。研究说明试验电压的增大虽然增加了试样烧蚀面积

但是由于放电时间减少

试验的严酷程度减轻。

Abstract

Current standard of inclined plane tracking test only concerns the condition under AC voltage.To understand the influence of DC voltage on erosion of silicon rubber in DC inclined plane tracking test

high speed camera and infrared thermography were used to observe arc discharge phenomena and temperature distribution on silicone rubber in contaminated fluid with a flow rate of 0.2 m L/min. The leakage current

mass loss and maximum erosion depth of the sample were recorded under different test voltage. Results show that incremental test voltage increases the length of arc and reduces the accumulated discharge time

the mass loss

and the maximum erosion depth. Although the increase of test voltage enlarges the erosion area

the test severity weakens since the discharge time is reduced.
