Abstract

The device has a current measuring unit measuring current circulating in a cylindrical strip (16) of a conductive layer (15), where change in the current value assures change in a vacuum space value to assure detection of loss of vacuum inside a vacuum cut-off apparatus (A). The strip forms vacuum and solid spaces (17, 18) in series. The vacuum space is formed between a movable electrode (5) or a fixed electrode (4) and an inner face (19) of a cylindrical insulating part (8) of a metal envelope (1). The solid space is formed between the inner face of the insulating part and the strip. The insulating part is partially made of insulating material such as ceramics. An independent claim is also included for a vacuum tube comprising a vacuum loss detecting system.
