摘要

环氧树脂是电力设备的重要组成部分

绝缘件生产工艺参数相对复杂

材料交联固化反应的影响因素较多。文中针对两种中压APG环氧树脂材料体系

在145℃下分别处理0～24 h

对其进行玻璃化转变温度、机械强度、击穿强度和耐电蚀痕等实验研究。结果表明

在145℃条件下

随着交联固化时间的增加

绝缘材料的机械性能提高60%～105%

击穿强度增加74%

介电常数在3.2～3.8之间

耐电痕性能达到1A2.5级标准。高温固化处理能够提高分子结构的交联度

改善环氧树脂的绝缘性能

但长时间处于高温环境会加速材料老化分解

研究证明

该环氧树脂配方最佳交联固化时间为8～16 h。

Abstract

Epoxy resin is an important part of power equipment.The production process parameters of insulating parts are relatively complex

and there are many factors influencing the cross-linking and curing reaction of materials.This study emphasizes two medium voltage APG resin systems

and curing 0～24 h unnder 145 ℃

glass transition temperature

mechanical performance

AC breakdown field strength and tracking and erosion are measured.Experimental results show that

under 145 ℃

with the increase of curing time

the mechanical performance of epoxy resins can be improved by 60%～105%

AC breakdown field strength is improved 74%.Moreover

the dielectric constant is stable between 3.2～3.8 and the tracking resistance is reached 1A2.5 standard.The degree of cross-linking can be increased under high-temperature

and the insulating properties of epoxy resins are improved.But the aging and decomposition of epoxy resins would be happened on long-term high-temperature.Studies have shown that for this epoxy resins the best treatment time is 8～16 h under high-temperature cross-linking curing.
