下部受流系统-SRT-同济大学中车捷运研究院

概述

磁浮列车沿着固定轨道行驶,通过地面电网供电，目前中低速磁浮列车通常采用三轨接触网受流方式。

Overview

Maglev trains run along fixed tracks and are powered by the ground grid. At present, medium and low-speed maglev trains usually adopt a three-track catenary current collection method.

供电轨伸缩缝处理方案

膨胀接头装置对环境温度的变化以及机车运营过程对接触轨纵向长度的影响进行热胀冷缩补偿，保证线路在不同的环境及机车运行环境下的正常机械、电气续接，确保机车运行安全。

有效改善噪声问题

Power supply rail expansion joint treatment plan

The expansion joint device compensates for the thermal expansion and contraction of the influence of the change in the ambient temperature and the longitudinal length of the contact rail during the operation of the locomotive, ensuring the normal mechanical and electrical connection of the line in different environments and the operating environment of the locomotive, and ensuring the safe operation of the locomotive.

Improve noise problem

下接触受流方式

受流器和接触轨布置在轨道梁两侧，一侧为正极，一侧为负极。

Bottom contact flow method

The current collector and the contact rail are arranged on both sides of the rail beam, one side is the positive pole and the other side is the negative pole.

优点:

1由于接触轨受流面向下，不易积尘埃、雪、霜等杂物，相应减少了维护工作量；

2在下部受流方式中，通过使用防护罩，可提高人身及接触轨的安全性；防护罩采用高性能GRP材料拉挤成型,可提高受电靴使用寿命；

3下部受流通过受流器产生上抬力取流，由于接触轨采用“悬挂”式安装，理论上，上抬力减弱了接触轨的挠度，在保证接触轨挠度一定，并满足受流器取流质量要求的条件下，接触轨支持间距可相对加大。

advantage:

1Because the contact rail is facing downwards，Not easy to accumulate dust、Snow,

2In the lower flow mode，by usingprotecting mask，Can improve the body and contact railsafety；The protective cover is pultruded with high-performance GRP material

3The lower part of the current is drawn through the current receiver to generate upward lifting force. Because the contact rail is installed in a "suspended" mannerThe contact rail support spacing can be relatively increased。
