刚性接触网悬挂瓷绝缘子破裂原因分析及对策

Analysis of Rigid Catenary Suspension Insulator Rupture and Countermeasures

悬挂瓷绝缘子是刚性接触网系统主要绝缘部件。通过对深圳地铁2号线刚性悬挂瓷绝缘子在运营期间出现的绝缘子破裂故障进行归纳,分析该类故障可能出现的原因,为后续绝缘子在日常维护、故障分析方面提供参考。同时亦可对刚性接触网在结构设计、施工等方面提供意见参考。

Suspension insulator is a main insulation part in rigid catenary system.Through summarizing the rupture failures of the rigid suspension insulator on Shenzhen metro Line 2,the possible causes of the fault are analyzed,in order to provide reference for the follow-up daily maintenance and fault analysis of catenary insulators.At the same time,this research may provide reference for the structural design and construction of rail transit rigid catenary system.
