Title: Vacuum valve
Inventor: YORITA MITSUMASA
IPC: H01H33/66
Filed: 1992-04-23
Abstract: PURPOSE:To improve the breaking performance by disposing a contact part, a taper part, and a radial or spiral slit at a first electrode, and providing a second electrode of which inner circumferential part is higher than an outer circumferential part of the first electrode, becoming higher gradually toward an outer circumferential part so as to speed up arc movement to the first and the second electrode. CONSTITUTION:A current flowing to an electrode 15 is throttled to one blade by a radial slit when an arc 31 is generated from a first electrode 15 having the radial slit, for example, so electromagnetic force applied to the arc 31 is increased to drive the arc 31 outward in the radial direction speedily. The arc 31 reaching an outer circumferential part of the electrode 15 is thus set to be easy to get in contact with a second electrode 14. Because a current flowing from a movable electrode rod 22 and a fixed electrode rod 21 flows through diagonal slits provided in a fixed electrode table 5 and a movable electrode table 8 to the electrode 14, an electromagnetic force is applied to the arc 31 to drive it forward, and the arc 31 rotates at a high speed to break the current.
