接触网分段绝缘器的动态特性分析及维护

对分段绝缘器的常见故障进行整理归纳,一方面利用力学原理对受电弓滑过分段绝缘器的过程进行受力分析,得出分段绝缘器在受电弓作用下的扭转角表达式,进而提出将分段绝缘器安装在跨中、保证分段绝缘器两端宽度等建议;另一方面对分段绝缘器的其他故障类型进行分析,提出改进措施.

Dynamic Performance Analysis and Maintenance of Section Insulator of Overhead Contact System

This paper sorts out and sums up the common faults of section insulator.On the one hand,get the deflection angle expressions from the force analysis of pantograph moving through section insulator,then realizes that the section insulator should be installed in the middle of the span and should keep two terminals of the section insulator be wider.On the other hand,the other types of section insulator faults also be analyzed,and then provided improvement measures.
