根据国家积极扩大内需、加快铁路基本建设的战略部署,到2010年,我国铁路营业里程将达到11万km,电气化率达到50%以上。铁路电气化是中国铁路发展的最终目标。而作为电气化铁路牵引供电系统的主体接触网,其性能的优劣直接决定着电力机车受电弓的受流质量,最终影响列车的运行速度与安全。而且接触网的特殊性主要表现在露天设置,对气候变化敏感;无备用性(决定它的脆弱性和重要性);机电复合性;负荷的不确定性和移动性。由于这些特殊性,接触网故障复杂而频发。因此对电气化铁路接触网的探讨任重而道远。
According to the national actively expand domestic demand, accelerating the construction of the
railway basic strategy, by 2010, China railway mileage will reach 110000 km, electrified rate above 50%. Railway electrification is the ultimate goal of China's railway development. And as the main body of catenary of electrified railway traction power supply system, its performance fit and unfit quality directly decides the quality of current electric otive pantograph, ultimately affect the speed of train running and safety. And the particularity of catenary in outdoor Settings, is sensitive to climate change; There was no spare (decided to the fragility and importance of it); Mechanical and pound; The uncertainty of load and mobility. Due to the particularity, catenary plex and frequent. So for electrified railway catenary to discuss a long way to go.
接触网担负着把从牵引变电所获得的电能直接输送给电力机车使用的重要任务。因此接触网的质量和工作状态将直接影响着电气化铁道的运输能力。接触网是沿铁路线上空架设的向电力机车供电的特殊形式的输电线路。其由接触悬挂、支持装置、定位装置、支柱与基础几部分组成。为了解决接触网的一些常见故障和提高接触网的性能,本文从接触悬挂、定位装置和支柱三个方面提出了自己的建议。
Contact for the transmit electricity directly from the traction substation for use in electric otive's important task. So the quality of the catenary will directly affect the working state and electrified railway transport capacity. Catenary is supply power to electric otives along
