摘要： PROBLEM TO BE SOLVED: To miniaturize electrodes and a vacuum valve by providing a first electrode having a slit with its axis inclined to a bottom part surface and a second electrode having a slit with its axis inclined at a angle decreased an angle of the slit of the first electrode from nearly 180 degrees to the bottom part surface on an internally cylindrical body so as to oppose to each other in a vacuum container. SOLUTION: An arc current generated between contacts 312 opposed to each other is synthesized by a current that flows along a slit 316 and a current that flows along a slit 2, and electromagnetic force acts on an arc by a magnetic field generated by each current in a vertical direction to an arc column. Drive force by the current which flows along the slit 2 acts on the arc when the arc approaches a central side between the contacts 312, and drive force by the current which flows along the slit 316 acts on the arc when the arc approaches the outside of the contacts 312. Therefore, the drive force of the arc can be obtained to suppress localized heating of the arc, and cutoff performance to a heavy-current region can be obtained and electrodes are miniaturized.

摘要： PROBLEM TO BE SOLVED: To provide a stable vacuum valve that is excellent in contact resistance and cut-off characteristics. SOLUTION: The contact material of a vacuum valve comprises a high conductivity constituent cupper or the like and an arc resistant constituent consisting of Cr, in which particles having a diameter in the range of 1-150 μm occupy at least 90 vol.%, and the ratio of the difference between the thermal expansion coefficient α900 at 900 deg.C, and the thermal expansion coefficient α50 at 50 deg.C, to the thermal expansion coefficient α900 at 900 deg.C of the contact material, [(α900 -α50 )×100/(α900 )] should be not less than 0.8% and not more than 12%. Thereby, the formation of a groove produced in the interface between a Cr particle and a Cu matrix after undergoing a brazing process is suppressed so that the stabilization of the static withstand voltage, contact resistance and cutoff characteristics can be realized.
