APPARATUS OF AIR COOLING FOR STATOR COILS OF SUPERCONDUTING MOTOR OR GENERATOR

摘要

PURPOSE: An air cooling type stator coil cooling device is provided to prevent insulation breakdown due to a contact between an upper coil and a lower coil by comprising an insulating plate between the upper coil and the lower coil of a stator coil. CONSTITUTION: A stator yoke(100) comprises multiple ventilation ducts(120). The multiple ventilation ducts inject or eject external air. A stator coil(200) comprises an upper coil(220) and a lower coil(240). An insulating plate(400) is formed between the upper coil and the lower coil. The insulating plate insulates the upper coil and the lower coil. A slot(300) repetitively forms a supporting part(320) and an exposing part(340). The supporting part is fixed at one side of the stator yoke. The supporting part surrounds the outside of the stator coil. The exposing part exposes the stator coil to outside.
