既有牵引变电所不停电改造技术

Uninterrupted Power Supply Transformation Technology for the Existing Traction Substation

结合施工现场实际,详细叙述了利用"高压室内馈线过渡,室外软母线倒接"的过渡方法对一次侧设备利用天窗点进行不间断供电改造施工,并采用"低压侧短路试验法"对主变压器进行电流回路极性校验。该技术缩短了施工时间,保证了施工安全,最大限度减小了施工对铁路运输的影响,可为今后类似工程提供参考。

Combined with the construction practice, the article describes in detail the reconstruction of uninterrupted power supply to side equipment in the way of high voltage chamber feeder transition, transition method of outdoor through soft bus reversal and the main transformer current loop polarity check with low voltage side short-circuit test method. The technology shortens construction period, ensures construction safety, and minimizes the influence of the construction on railway trans-portation. It also can provide reference for similar engineering in the future.
