Scope

GB/T 45658-2025 is the English-translated version of 轨道交通牵引供电系统交流25kV同相供电装置.

GB/T 45658-2025 is the Chinese national standard covering the converter that lets adjacent traction sections be fed from the same phase — the negative sequence control that keeps a single-phase traction load from unbalancing the three-phase grid behind it, the reactive power compensation and the harmonic suppression, the current control, the protection and the safety interlocks, the local or remote operation, the clearances, creepage and dielectric strength, and the efficiency, temperature rise, noise and continuous running tests. First edition, with the power supply operation safety control standard GB/T 45659-2025. Under the National Railway Administration. In force from 1 December 2025. Issued on 30 May 2025, it has been in force since 1 December 2025.
