    The invention discloses a subway electric energy efficient transmission structure with vibration and noise reduction effects, and relates to the technical field of track engineering power supply, the subway electric energy efficient transmission structure comprises a main body, a supporting assembly is arranged outside the main body, the supporting assembly comprises a supporting seat, and the supporting seat is fixedly installed outside the main body; the exterior of the supporting seat is fixedly connected with an insulating blocking frame, and one side of the supporting seat is fixedly provided with a sawtooth fixing plate. Compared with an existing scheme that a stainless steel band and an aluminum alloy matrix are mechanically compounded, the bonding force is higher. In addition, no obvious physical interface exists between the metal covering layer and the aluminum alloy rail base body, and the conductivity between the two layers of metal can be remarkably improved. Compared with an existing scheme that a stainless steel band and an aluminum alloy substrate are mechanically compounded, the problems that due to long-term use, a gap between the stainless steel band and the aluminum alloy substrate is enlarged and even the stainless steel band and the aluminum alloy substrate are separated, conduction is not smooth, upper pollutants can easily flow to a ballast bed, the ground insulation performance of the support is reduced, and stray current in the ballast bed is reduced are solved.

    本发明公开了一种具备减振降噪效果的地铁电能高效传输结构，涉及轨道工程供电技术领域，包括主体，所述主体的外部设置有支撑组件，所述支撑组件包括支撑座，所述支撑座固定安装在主体的外部，所述支撑座的外部固定连接有绝缘阻挡架，所述支撑座的一侧固定安装有锯齿固定板。本发明相较于现有的不锈钢带与铝合金基体机械复合的方案，结合力更强。而且，金属覆盖层与铝合金轨道基体之间没有明显的物理界面，两层金属之间的导电能力将显著提升。相较于现有的不锈钢带与铝合金基体机械复合的方案，不会因为长期使用导致二者间隙变大甚至脱开，而引起导电不畅，上部污染物可轻易地流淌到道床上，降低支架的对地绝缘性能，降低道床中的杂散电流。
