CORE MOUNTING APPARATUS FOR TRANSFORMER

摘要

PURPOSE: A core coupling device of a transformer is provided to install a vibration weight damper in a part with which a core is coupled, thereby reducing noise and vibration which occurs in the core during the operation of the transformer. CONSTITUTION: An upper frame is coupled with the upper part of a laminated core(10). A lower frame is coupled with the lower part of the laminated core. A fixing bar is coupled with a core leg part. First coupling units for coupling the core with the upper frame are placed in the upper part of the upper frame and the core. Second coupling units for coupling the core with the lower frame are placed in the lower part of the lower frame and the core. Third coupling units for coupling the fixing bar with a core leg are placed in the fixing bar and the core leg. A vibration mass damper(60) is installed in a coupling unit of the core. A bolt(50) is inserted into a coupling hole(14) of the core.
