快速受流是指快速运行的电力机车通过受电弓与接触线的滑动取得电能并传给电力机车的过程。受流过程中,在电气方面和机械方面相互依赖,相互制约,相互作用的受电弓和接触线的状态好坏对受流质量起决定性作用。在此,仅就接触线高度对快速受流质量的影响进行分析,提出粗浅的看法和建议,与同行商榷。一、快速对接触线高度的要求对接触线高度而言,无论是常速还是快速,都要求悬挂点接触线高度必须严格等高,其相对误差越小越好;跨中设置的预留弛度 Rapid flow is the rapid operation of the electric locomotive through the pantograph contact with the sliding line to obtain electricity and passed to the process of electric locomotive. During the process of flow, the status of the pantograph and the contact line which are interdependent and interacting with each other in the electrical and mechanical aspects plays a decisive role in the quality of the flow. Here, only the height of the contact line on the impact of the rapid flow quality analysis, put forward a superficial view and suggestions, and colleagues to discuss. First, the rapid requirements of the contact line height For the contact line height, whether it is constant speed or fast, require suspension point contact line height must be strictly contour, the smaller the relative error as possible; set aside in the cross-relaxation degree
