Abstract

PURPOSE:To reduce the temperature rise of a 3-phase reactor core and to approximately uniformalize the temperature distribution by employing an optimum cooling duct position or yoke section. CONSTITUTION:The sectional areas of outside yokes 4a, 4b are approximately equalized to the area contacted with a core leg 3 and outside yokes 4a, 5a. Cooling ducts 4c or 5c is provided at the position where the sectional areas of the inside yokes 4b and 5b become equal to the area contacted withthe inside yoke 4b or 5b or outer than that. Insulating oil flowing in a cooling duct 4c or 5c cools the yokes 4, 5, thereby uniformalizing the temperature rise distribution.
