Vacuum insulated switching apparatus
摘要:
In a vacuum bulb 1 composed of a grounded metallic vessel 2, the reliability in monitoring and measuring the vacuum pressure can be improved by providing a vacuum pressure measuring terminal 30 at a side plane of the vessel 2 to electrically separate the main circuit 13 from the measuring terminal 30.
