随着电气化铁路在我国的发展,提高电化区段列车速度的研究越来越迫切。在电化区段提高速度其关键是如何解决受电弓的离线问题。笔者针对这个问题发表以下观点: 一、离线的主要原因产生离线的原因是多种多样的,笔者认为主要原因是: 1.硬点下的离线这种离线经常发生在接触悬挂的硬点处,如定位点、吊索悬挂点、电分相、电分段及导线接头和补强处。 2.弓网接触不良造成的离线主要发生在冬季或污染严重的区段。原因是导线上的冰、雪、煤、油、灰尘等污物使导
With the development of electrified railway in our country, the research on how to improve the train speed in electrified railway is more and more urgent. In the electrification zone to speed up the key is how to solve the pantograph off-line problem. The author published the following views on this issue: First, the main reason for offline offline is due to a variety of reasons, I think the main reason is: 1. Offline under the hard spots This off-line often occurs in contact with the suspension of hard points, Such as the positioning point, sling suspension point, the electricity phase, the electrical section and wire joints and reinforcements. 2. Off-line due to poor bow-net contact occurs mainly in winter or heavily polluted sections. The reason is that the wires on the ice, snow, coal, oil, dust and other dirt guide
