PURPOSE:To increase the insulating withstand strength, and to eliminate or simplify the tape winding insulators of output leads, lead connection and lead bushing by forming a lead box in a sealed structure and sealing SF6 gas therein. CONSTITUTION:A drawer of output leads 2 is formed at the lower portion of an outer box 1 of a rotary electric machine. The leading port 1a of the leads 2 of the box 1 is sealed by a sealing cover 1b. A lead box 3 is clamped with bolts 4 at the lower portion of the box 1. A lead bushing 5 is mounted at the box 3. Th e electric connection of the lead 2 of the machine with the bushing 5 is achieved by the lead connection 6. After all are completely connected, SF6 gas is sealed and filled from a sealing port 8 into the box 3. |
