电气化铁路接触网软横跨定位器、悬吊滑轮电气烧损原因与对策
Causes and Countermeasures for Electric Burn-down of Headspan Suspension Steady Arm and Suspension Pulley of Electrified Railway Overhead Contact System
摘要
Abstract
This paper focuses on five failures of headspan suspension in overhead contact system due to dispersion of traction current of headspan suspension that burns down the steady arm and suspension pulley. By simulating the electric locomotive collecting current at different locations, these failures are analyzed to trace the causes for the dispersion according to the principle of electric circuit and the characteristics of each device. Countermeasures are formulated and implemented with good results. Comprehensive analysis of these five failures is conducted to find out the common causes and it is the insufficiency of the main circuit that proves to be the very cause for the failures. In order to solve this kind of problem, the author proposes the principle for inspecting the insufficiency of the main circuit, which may provide reference for designers and operators.关键词
