    摘要： In a puffer type gas circuit breaker comprising at least a pair of main movable and fixed contacts, a puffer device and a pair of preinsertion resistor contacts inserted electrically in parallel with the main movable and fixed contacts, the preinsertion resistor contacts are closed prior to the closing of the main movable and fixed contacts, and are separated a short time after the main movable and fixed contacts have been closed.

    摘要： The iron core characteristics of an amorphous iron core transformer degrade significantly when machining from material into a transformer. This phenomenon is suppressed to improve the iron core characteristics of the finished transformer products. In the present invention, an insulating thin film is formed in at least one side of an amorphous ribbon, and is formed in at least one for each plurality of amorphous ribbons of iron core material. Moreover, in the surface of the amorphous ribbon that is the iron core material of the amorphous iron core transformer, silane or the like is vapor deposited to form an insulating thin film, the insulating thin film being formed in the thickness of approximately 1 μm. With such structure, an increase in eddy current loss occurring when machining from the material into a transformer is suppressed to reduce no-load loss of the transformer.
