铁路机车运行的过程中,机车的弓网关系受到影响、受流稳定状态遭到破坏是影响铁路正常工作的常见问题,而接触网硬点的产生则是导致这些现象的主要原因之一。降低接触网硬点带来的影响,保持弓网间的接触正常和稳定受流是确保电气化铁路安全运行的基础。为了解决以上接触网硬点的问题,本文通过对当前我国电气化铁路接触网现状的分析,对硬点的产生、原因及危害进行探讨,最终提出应对接触网硬点的防治措施。 During the operation of railway locomotives, the bow-tie relationship of locomotives is affected, and the steady-state flow damage is a common problem that affects the normal work of the railway. The occurrence of catenary hard points is one of the main causes of these phenomena. Reduce the impact of the hard point of the contact network to maintain contact between the bow net normal and stable flow is to ensure the safe operation of electric railway base. In order to solve the above problem of the hard spot of the catenary, this paper analyzes the current situation of the catenary in our country, discusses the causes, the causes and the harms of the catenary. Finally, it puts forward the measures to deal with the catenary hard spots.
