Abstract

PURPOSE:To allow replacement of the coil and iron core of each phase exclusively, in case of accident, by separate constitution of respective phase basis of iron core and coil contained in a tank. CONSTITUTION:The internal of a tank 1 of a three phase transformer is divided into three sections 3a-3c by partition boards 2a, 2b. Each section 3a-3c has respectively each phase unit consisting of monophase iron cores 4a-4c and coils 5a-5c which are wound up to the main leg of each coil 4a-4c. The yoke end surface of each core 4a-4c is connected respectively through the partition boards 2a, 2b. The contact part of each iron core at the partition boards 2a, 2b has magnetic material with the same characteristic as an iron core so as not to hinder the magnetic path constitution of adjacent cores 4a 4b and 4a 4c. Such a constitution allows, in case of accident, taking out the iron core and coil in the corresponding phase from a tank 1 and incorporating spare ones for exchange.
