摘要
在油隙的电极间隙放置一定尺寸的绝缘屏障、或给正电极包扎数层绝缘覆盖 ,均能改善油隙的电场均匀度 ,阻止“杂质小桥”形成 ,限制泄漏电流 ,有效提高油隙的绝缘水平。本文通过对 2 5 # 变压器油油隙的绝缘屏障和电极覆盖研究试验 ,充分说明这个问题。
It is known that the insulating barrier and electrode coating can hinder the formation of the 'impurity bridge' in the oil gap and improve the uniformity of electric field. This paper presents experimental results to show that the dielectric strength of an oil gap is apparently increased by the application of insulating barrier and electrode coating.
