LEAK TASTE EQUIPMENT OF WATER COOLED STATOR BARS FOR GENERATOR AND LEAK TASTE METHOD

摘要

An apparatus and a method for testing a winding leak of a stator for a generator are provided to improve reliability inside a winding by performing a leak test in a vacuum state. A heating device(40) is installed between a winding and an air supplier(20), and sprays a heated air inside the winding after heating an air supplied from the air supplier. A control part(50) includes an exhaust mode part, a dry mode part, a vacuum mode part, and a vacuum dry mode part. The exhaust mode part exhausts the air after spraying the air inside the winding. The dry mode part heats the air through the heating device. The vacuum mode part makes a vacuum state inside the winding by operating a vacuum pump.
