枢纽地区既有直供牵引变电所高压室改造过渡方案

枢纽地区直供牵引变电所27.5 kV高压室停电困难,对其改造施工难度大。采用模块化箱式高压室临时替代既有高压室的过渡方案,解决了枢纽地区直供牵引所高压室无法改造施工的难题。通过模块化箱式高压室的不同组合方式,可同时满足枢纽地区开闭所、正线牵引变电所等多种牵引变电所亭高压室的改造过渡需求。

The 27.5 kV high-voltage chamber of traction substation has difficulty in power outage,so it is difficult to rebuild it.The transition plan of the modular box-type high-voltage chamber temporarily replaces the existing high-voltage chamber,solves the problem that the high-voltage chamber of the traction substation in the hub area can not be reconstructed.Through the different combination of modular box-type high-voltage chamber,it can also meet the transition requirements of various traction substations,such as the switching post of the hub area,the traction substation of the main line and so on.
