JYN1-35(NW)型防凝露防污秽开关柜中环氧树脂穿墙套管的电场分析
摘要
通过对JYN1-35(NW)型开关柜中防凝露防污秽环氧树脂穿墙套管的电场计算
分析了此类套管的电场分布与起晕电压(U
c
)和闪络电压(U
f
)的关系。新设计的套管的U
c
及U
f
均有较大提高
套管顺利通过了按国标及IEC有关标准进行的测试。
Abstract
Numerical calculation and analysis of the epoxy bushing electric field in JYN1-35(NW) cubicle
indicate that corona voltage(Uc) and flashover volt-age (Cf) of the bushing are related with electric field distribution. Ce and Uf of the optimized bushing are promoted effectively.
