Dianci bileiqi, 2008 介绍了晋东南-南阳-荆门1000kV交流试验示范工程中线路用盘形悬式瓷、玻璃和复合绝缘子的使用情况。分析研究了特高压绝缘子运行的积污、电气、机械和劣化等性能方面的情况,认为:应加强对特高压绝缘子积污特性、绝缘子直径对雨闪特性的影响,串形对绝缘子的机械特性影响,绝缘子运行的可靠性和劣化特性及机械振动特性的研究。建议待建特高压工程支柱绝缘子采用双柱并列式或三角锥式;及时开展盘形悬式瓷绝缘子劣化率、复合绝缘子憎水性和机械特性及钢脚腐蚀检测等工作 ...

Dianci bileiqi, 1995 提高绝缘子湿闪电压的方法发明用于加强电器设备的外绝缘强度，特别是在强污秽情况下的外绝缘强度。冲洗绝缘子表面污秽利用具有憎水性溶液“”，它能在绝缘子表面和孔隙间形成稳定的憎水性保护膜，这是由于组成该膜的成分是“”和污秽中的绝缘性成分。这一技术可使绝缘子...

Dianci bileiqi, 2019 绝缘子自然积污可分为两个过程,自然污秽粘附过程及降雨清洗过程。为研究自然积污特性,通过挡雨装置设置无降雨影响的自然积污试验环境,在无降雨影响下进行了不带电的自然积污试验,测量等值盐密及等值灰密表征绝缘子污秽程度并用于分析绝缘子积污特性。试验结果表明:无降雨影响时,绝缘子污秽程度和积污时间有密切联系,在污秽程度较低时,绝缘子积污程度随时间呈现线性增长趋势;随着污秽程度的增加,将会出现饱和现象或积污加快现象。同时,不同类型的绝缘子积污速度有所区别。在材质方面 ...

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 ...
