Locomotive transformer and winding device therefor

摘要

The locomotive transformer has a superconductive coil arrangement (1) which includes several winding groups (W1-W4). These groups (W1-W4) are arranged on a core in a cryostat container and are associated with respective drive parts. The winding groups (W1-W4) each have a primary winding (OS1-OS4), a secondary winding (US1-US4) and at least one shunt winding (S11-S42). The primary windings (OS1-OS4) are connected in series. Each group (W1-W4) preferably has two shunt windings (S11-S32) which are connected pair-wise, in parallel. These may serve to generate an auxiliary voltage. The core may be formed as a split strip core with an air-gap.
