摘要

目前的染污绝缘子的电气特性主要采用在蒸汽雾湿润条件下进行。试验经验表明

蒸汽雾湿润过程中绝缘子湿润时间难以控制

且试验过程中雾室内的温度也上升

这些影响因素使蒸汽雾试验与自然条件下绝缘子闪络时的环境条件明显不同。文中在人工气候室内利用超声波雾发生装置研究了复合绝缘子FXBW-35/70的交流雾闪特性。试验结果表明

不同雾水电导率下

绝缘子的闪络电压随着染污盐密ESDD的增加而降低

并呈负幂指数函数变化关系;随着雾水电导率的增加其闪络电压也降低

其可以表示为负指数函数关系。在输电线路外绝缘设计时应考虑雾的染污程度的影响

研究结果可为工程应用提供有价值的参考。

Abstract

At present

the steam fog wetting method is frequently used for the electrical characteristics of polluted insulators in artificial fog tests.However

experimental experience shows that

it is difficult to control wetting time with this steam input rate.Moreover

the temperature in the chamber rises over the duration of the test.Both of these factors make the fog test less representative.Based on measurements of ac fog flashover performance of FXBW-35/70 composite insulator in the artificial climate chamber that make use of arrays of ultrasonic fog nozzles fed with water build up fog faster.The tests show that the relationships between flashover voltage and Salt Deposit Density（SDD）can be expressed as a negative exponential function.However

the fitting formulas

which are simulated on ac pollution flashover voltages at the various pollution degrees

are consistent under different fog water conductivity.Moreover

the relationships between flashover voltage and fog water conductivity can be expressed as an exponential function.Therefore

the external insulation selection of transmission lines should consider the influence of the fog conductivity.The results of the research may provide valuable reference for engineering applications.
