STATIONARY INDUCTION APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide small-size stationary induction equipment with improved cooling efficiency by improving heat transfer of a cooling medium in a horizontal cooling path and coil surfaces. SOLUTION: A string-like obstacle 13 is disposed between horizontal interval segments 4 neighboring in the circumferential direction. This obstacle 13 is supported by bridging between respective horizontal interval segments over the whole disc coil 3 and hooked alternately at the upper part and the lower part of neighboring horizontal interval segments 4. The obstacle 13 is disposed, such that the flow of an insulating fluid in a horizontal cooling path 5 is not blocked completely, but is made turbulent.
