Abstract (en)

[origin: US2017316864A1] A configuration for the rapid replacement of a faulty multiphase transformer includes a plurality of single-phase transformers each of which has a housing filled with an insulating fluid and in which a core having a higher-voltage and a lower-voltage winding is disposed. At least one bushing socket is connected by a winding connection lead extending within the housing to the higher-voltage or lower-voltage winding. At least one high-voltage feed-through or bushing can be inserted into the bushing socket and a cooling module, which can be detachably connected to the housing and is filled with insulating fluid, cools the insulating fluid.
