35kV dry-type traction rectifier transformer for rail transit

ZQSCB-3300/35
This product is primarily used in urban rail transit, where its rectifier unit provides traction DC power for subways. The product capacity ranges from 2000kVA to 4000kVA. The primary windings of its two rectifier transformers have phase angles of +7.5° and -7.5° respectively. When both transformers operate simultaneously, they form a 24-pulse rectification circuit. The 12-phase 24-pulse dry-type traction rectifier transformer meets all performance indicators required for subway power supply, and it is particularly effective in mitigating the impact of higher-order harmonics from the rectification device on the power grid.

  • Product Advantages
    It has strong overload capacity and meets the requirements of Class VI load for heavy traction in subway systems.
    Low energy consumption, fully meeting the energy-saving application requirements of rail transit.
    It has strong moisture-proof and anti-pollution flashover capabilities, meeting the special environmental requirements of subways.
    The product has low partial discharge, high mechanical strength, and strong short-circuit resistance.
    It can effectively suppress the harmonic distortion on the grid side caused by the rectifier.
  • Application scenario
    Due to the particularity of their operating environment, most 24-pulse traction rectifier dry-type transformers for rail transit are applied in subway, light rail, and other rail transit projects. These products have been successfully applied in subway projects in Tianjin, Zhengzhou, Dalian, Harbin, Changchun, Luoyang, Jinan, Nanjing, Hangzhou, and Fuzhou
