Dianci bileiqi, 1976 第七节影响绝缘子机械强度的因素绝缘子在运行过程中要受到机械负荷的作用。通常线路盘形悬式绝缘子悬垂串受到由导线自重、复冰重量和风力等引起的拉伸负荷的作用,耐张串主要承受常以吨计的导线张紧力的作用。支持类绝缘子(如线路针式绝缘子,横担绝缘子、支柱绝缘子等)和套管通常要受到导线重量和振动系统短路电动力、风力和自重等所引起的弯曲负荷的作用。隔离开关和母线支柱绝缘子除了受到上述弯曲负荷作用以外,还严重地受到设备操作(合闸或分闸 ...

Gaoya dianqi, 1965 随着电力系统的容量日益扩大,输电电压日益提高,所需绝缘子电压等级也随之提高。但目前单个电瓷绝缘子电压一般都在110千伏以下(指棒式、盘形及针式绝缘子),更高电压等级如330千伏、500千伏及以上就需由多个缘绝子串联组成悬式绝缘子链或支持绝缘子柱。由于绝缘子链(或柱 ...
