添加陶瓷粉对复合绝缘子微观电特性的影响

摘要/Abstract

摘要：

陶瓷绝缘子大量退运后对性能良好的瓷体采取掩埋措施,不仅浪费资源而且污染环境,基于此本文将瓷体研磨后添加到硅橡胶材料中,替代了部分铝粉和气相法白炭黑,且对其进行了耐漏电起痕、热刺激电流（TSC）以及傅里叶变换红外光谱分析的试验,比较了不同比例的陶瓷粉对硅橡胶的电特性的影响,试验结果表明陶瓷粉可以明显改善硅橡胶的电特性。

Abstract:

What the porcelain body of good performance was buried not only waste resources but also pollute the environment after a large number of ceramic insulators returned. Based on these, we added grinded ceramic body into the silicon rubber material for replacing some of the aluminum powder and fumed silica. And it’s used to make Experimental. The measurements include tracking resistant, thermally stimulated current (TSC) and Fourier transform infrared spectroscopy. The effects of adding different proportions of ceramic powder on the electrical characteristics of silicone rubber are compared. The results showed that the ceramic part can significantly improve the electrical characteristics of the silicone rubber.

Key words: Silicone rubber, composite insulators, aging, return shipment, ceramics
