        概述

        磁浮列車沿著固定軌道行駛,通過地面電網供電,目前中低速磁浮列車通常采用三軌接觸網受流方式。

        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.

        供電軌伸縮縫處理方案

        膨脹接頭裝置對環境溫度的變化以及機車運營過程對接觸軌縱向長度的影響進行熱脹冷縮補償,保證線路在不同的環境及機車運行環境下的正常機械、電氣續接,確保機車運行安全。
        • 有效改善噪聲問題

        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

        下接觸受流方式

        受流器和接觸軌布置在軌道梁兩側,一側為正極,一側為負極。

        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.

        優點:

        1由于接觸軌受流面向下,不易積塵埃、雪、霜等雜物,相應減少了維護工作量;

        2在下部受流方式中,通過使用防護罩,可提高人身及接觸軌的安全性; 防護罩采用高性能GRP材料拉擠成型,可提高受電靴使用壽命;

        3下部受流通過受流器產生上抬力取流,由于接觸軌采用“懸掛”式安裝, 理論上,上抬力減弱了接觸軌的撓度,在保證接觸軌撓度一定, 并滿足受流器取流質量要求的條件下,接觸軌支持間距可相對加大。

        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。
