  • Stationary induction apparatus
    Patent number: 8547193
    Abstract: In a stationary induction apparatus, an inter-partial-coil insulating plate and a plurality of inter-partial-coil spacer insulators form a refrigerant flow path in conjunction with each other. A space having an inter-partial-coil insulation dimension for withstanding an abnormal voltage is formed between a pair of partial coils. The inter-partial-coil insulating plate and the inter-partial-coil spacer insulators support both the pair of partial coils at an insulated state so as to maintain the inter-partial-coil insulation dimension. The insulators are arranged so as to be overlapped with each other in the direction in which mutually adjacent partial coils are opposed to each other.
    Type: Grant
    Filed: October 18, 2010
    Date of Patent: October 1, 2013
    Assignee: Mitsubishi Electric Corporation
    Inventors: Soichiro Kainaga, Takao Tsurimoto, Takahiko Ishikura, Hirotaka Muto, Hiroki Otera, Tetsuya Matsuda, Koji Kise, Noboru Hosokawa, Kiyoyuki Ishikawa, Koji Shinya, Ryuichi Nishiura
