PROBLEM TO BE SOLVED: To provide a vacuum valve with the voltage-resisting performance improved. SOLUTION: In the vacuum valve 100, a narrow-groove section 1b is arranged coaxially with a cylindrical ceramic insulated container 1, inside a connection section 16 corresponding to a section for brazing a deep plate-shaped end plate 2 at an end of the insulated container 1, and a metallized layer 1a is continuously arranged inside the narrow groove section from the end of the insulated container 1. The end plate 2 and the insulated container 1 are blazed via the metallized layer 1a. As a result, the electric field of a metallized layer 1a end section is relaxed, and the vacuum valve which dispenses with special shielding can be provided. COPYRIGHT: (C)2011,JPO&INPIT |
