复合绝缘子在“V”形串中的应用研究

Investigation on Application of Composite Insulator for "V"String

为研究"V"形串中复合绝缘子长期运行受压对绝缘子性能的影响,进行了"V"形串复合绝缘子的受力试验。监测了角度偏移、受压复合绝缘子的应力及水平荷载和垂直荷载,并在多次试验后对受压绝缘子进行了机械破坏负荷试验。结果表明,在"V"形串中复合绝缘子受压并不影响其机械性能,但应注意频繁弯曲是否会造成密封破坏。

The mechanical test on 'V'string insulators was performed on composite insulators for investigating the long term buckling effect on composite insulators.The angle deflection,buckling stress of insulator,horizontal load and vertical load were recorded.The mechanical failing load test was performed on buckling insulator.It was found that the mechanical performance of composite insulators was un-influenced by buckling,but care should be taken to avoid housing seal failure by frequent buckling.
