Document Type and Number:
Japanese Patent JP7238803
Kind Code:
B2
Abstract:
To provide a vacuum valve in which, when the vacuum valve is downsized, radiation heat of arc discharge is prevented from being accumulated and a portion in the inside of the vacuum valve is also prevented from being deformed.SOLUTION: Disclosed is a vacuum valve 100 according to the present disclosure, in which a wavelength selective heat radiation absorber 13c for absorbing electromagnetic waves in a predetermined wavelength range is arranged on the surface of an internal portion which is a portion in the inside of the vacuum valve, and the internal portion is directly or indirectly connected to the external part which is the portion in the outside of the vacuum valve, whereby a heat radiation path from the wavelength selective heat radiation absorber 13c to the surface of the portion in the outside is constituted.SELECTED DRAWING: Figure 2
