摘要

已经确定，高度潮湿的操作条件被称为“恶化的服务条件”，是中压开关设备组件有机绝缘退化的促成因素之一。本文量化了相对湿度和电压应力对双酚环氧树脂铸造开关柜元件性能的有害影响。以损耗因数和泄漏电流为降解参数，进行了短时和长时耐久性试验。生成的数据用于开发广义系统模型，以预测环氧树脂铸造设备在潮湿条件下的耐久性。

Characterisation of epoxy resin bushings under aggravated service conditions

It has been identified that highly humid operating conditions known as 'aggravated service conditions' are one of the contributory factors in the degradation of organic insulation in medium voltage switchgear components. This paper quantifies the deterious effects of relative humidity and voltage stress on the behavior of Bisphenol epoxy resin cast switchgear components. Short term and long term endurance tests were conducted using loss factor and leakage current as degradation parameters. The data generated is used to develop a generalised system model to predict the endurance of epoxy resin cast equipment under humid conditions.<>
