环氧复合材料绝缘件是GIS/GIL等设备的重要组成部分,也是制约设备绝缘水平的核心部件。工程运行经验表明,气体绝缘设备故障或事故率远超预期,而且许多的接地故障均是由环氧复合绝缘子的沿面闪络引起的,所以环氧复合绝缘子的绝缘性能至关重要;另外,从电力设备技术的发展来讲 ...

500kV交流岭深线路复合绝缘子的积污特性

Gaoya dianqi, 2014
绝缘子表面积污状况与污区划分及外绝缘的选择密切相关,是外绝缘的基础性工作之一。为此,文中选取10支深圳地区岭深线路交流500 k V复合绝缘子并对其积污特性展开研究。对测试结果进行方差分析发现,岭深线不同地形条件绝缘子整体积污状况接近,而同一支绝缘子不同部位表面积污状况存在差异,表现为:靠近绝缘子串两端的伞裙单元盐密值较大;绝缘子伞裙上表面积污重于下表面。上述测试结果表明复合绝缘子表面积污存在不均匀性,在进行复合绝缘子人工污秽试验时,应充分考虑复合绝缘子的积污特点。

混凝土复合绝缘子

Dianci bileiqi, 1994
混凝土复合绝缘子复合混凝土是指浸过胶的混凝土，它的绝缘强度可达４０ｋＶ以上，并具有优良的机械强度。在这十年期间，复合混凝土绝缘子在美国６９ｋＶ输电线路上的应用和运行十分成功，在工作电压为１３８ｋＶ的输电线路中也同样达到较为满意的效果。复合混凝土绝缘子...
