本文主要介绍人工污秽绝缘子在试验中的湿润过程,得出了依绝缘子表面凝露以及水滴粘着而确定的湿润方向计算法。并确知,闪络屯压、清洗效果以及泄漏电流等均依所有雾的状态(雾的产生方法,雾中的水滴大小、分布、速度,以及温度)而定。

The honorifics, or polite language forms, are one of the characteristics of the Japanese language. The period after the war has seen many criticisms of the confusion reigning in this domain; many have asked for their simplification.

环氧树脂作为空气绝缘开关柜主要的绝缘材料,在高温、高湿地区运行时容易受到昼夜温差的影响,环氧树脂表面易出现严重的凝露现象,可能会引起表面闪络影响到开关柜的正常运行。本研究以E-51型环氧树脂作为基体,MTHPA为固化剂,制备酸酐类交联体系环氧树脂样品。通过建立凝露放电平台模拟开关柜运行过程中环氧树脂表面凝露放电现象,并采用静态接触角、扫描电镜(SEM)、红外光谱(FTIR)等方式对样品进行分析。结果表明:随着温差、湿度、污秽度的增加,环氧树脂表面凝露质量也随着增加,且温差对凝露质量的影响最大 ...

[问]SF6气体中的水分会带来那些危害?[答]水分的危害最主要的是在电弧作用下SF6气体产生的反应.在电弧或电晕的作用下,SF6气体将被分解为SF4,SO2F2(氟化硫酰),SOF2(氟化亚硫酰),HF(氢氟酸)和SO2等有害物质.生成物HF是所有酸中腐蚀性最强的.SO2遇水会生成亚硫酸H2SO2,它也是一种腐蚀件物质.由此看来如果SF6气体中含有水分,不仅会降低设备的绝缘强度而且危害人体健康.另外SF6气体中混杂的水分通常以水蒸汽形式存在,在较低温度下,水蒸汽可能凝结成露附着在零件表面 ...

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
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(Uc)和闪络电压(Uf)的关系。新设计的套管的Uc及Uf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。
