Scope
JB/T 10693-2022 is the English-translated version of 城市轨道交通用干式牵引整流变压器.
Dry-type traction rectifier transformers for urban rail transit are covered by JB/T 10693-2022, a recommended Chinese machinery industry standard.
It sets out the service conditions, the product models and connection methods, the technical requirements, the test items and test methods, the reliability provisions, and the requirements for nameplates and signs, packaging, transport and storage.
The standard governs the manufacture of dry-type traction rectifier transformers used as rectifier power supplies in traction rectifier substations of urban rail transit systems such as metros, light rail and urban railways, at voltage levels of 35 kV and below, with rated capacity from 315 kVA to 4400 kVA and rated frequency 50 Hz.
It supersedes JB/T 10693-2007, and was issued on 30 September 2022 with effect from 1 April 2023.
