Abstract:
Disclosed is a vacuum circuit breaker ( 1 ) including a vacuum interrupter ( 3 ) accommodated in a ground tank ( 2 ) filled with insulating gas. At least one of a fixed electrode ( 10 ) and a movable electrode ( 11 ) of the vacuum interrupter ( 3 ) uses an electrode material in which particles containing a solid solution of a heat resistant element and Cr are finely and uniformly dispersed and in which Cu textures as a high conductive component are finely and uniformly dispersed. The electrode material contains 20 to 70% by weight of Cu, 1.5 to 64% by weight of Cr and 6 to 76% by weight of the heat resistant element relative to a weight of the electrode material. The particles of the solid solution in the electrode material have an average particle size of 20 μm or smaller.

Claim (Index 3):
A vacuum circuit breaker comprising a vacuum interrupter accommodated in a casing filled with insulating gas, the vacuum interrupter comprising:\n a vacuum container having an insulating tube and seal members for sealing both ends of the insulating tube; and a pair of contacts arranged in the vacuum container so as to be contactable with or separable away from each other, and being fixed to conductive shaft members, wherein at least one of the contacts comprises an electrode material containing a Cu phase and a phase of solid solution particles uniformly dispersed in the Cu phase, the solid solution particles being formed of a solid solution of a heat resistant element selected from Mo, W, Ta, Nb, V and Zr and Cr; wherein the electrode material comprises 20 to 70% by weight of Cu, 1.5 to 64% by weight of Cr and 6 to 76% by weight of the heat resistant element, relative to a weight of the electrode material, with the balance being unavoidable impurities; and wherein the solid solution particles contained in the electrode material have an average particle size of 20 \u03bcm or smaller, and are uniformly dispersed in the Cu phase with a dispersion state index of 1.0 or lower.
