Abstract

PURPOSE:To facilitate the inspection, research, maintenance and repair of a liquid-cooling passage by cnnecting the ends of connecting tubes arranged between the assembling ring of cooling liquid and stator coils in a cap nut type, thereby facilitating the attachment and detachment of the tube. CONSTITUTION:A connecting tube 3 made, for example, of a flexible insulating tube is arranged between the assembling ring 2 of cooling liquid and stator coils 4. A cap nut 6 is provided at the end of the tube 3, a projection 8 is formed partly on the outer periphery of the tube 3, and threads are formed on the outer periphery of the joint 7 of the ring 2. A packing 11 is inserted between the nut 6 and the joint 7, and the tube is connected to the ring in a cap nut type. The tube 3 is connected to the coils 4 in the similar cap nut type.

収される。FIG. 1 schematically shows a stator winding water-cooled turbine generator as an example of the structure of a liquid-cooled rotating electric machine. 1st
In the figure, cooling water collects from the inlet pipe (1) into the inlet set 3J (2a) in the machine and is distributed to the stator windings (4) through the inlet connecting pipe (3a). The stator winding (4) has a hollow strand structure, and the cooling water cools the inside of the winding while reaching the other end of the winding, passes through the outlet connecting pipe (3b), and enters the outlet collecting ring (2b). and collected outside the machine through the outlet pipe (5).
