ELECTRODE MATERIAL FOR VACUUM CIRCUIT BREAKER AND METHOD FOR PRODUCING SAME |
摘要 |
<p>An electrode material for a vacuum circuit breaker, which can further improve electrical characteristics required for a vacuum circuit breaker. A method for producing the electrode material for a vacuum circuit breaker. An atomized Cu-Cr alloy powder, 20-30% by weight of a thermite Cr powder and 5% by weight of an electrolytic Cu powder are mixed and sintered in the solid phase, thereby obtaining an electrode material for a vacuum circuit breaker, said material containing a solid phase sintered body having a total Cr content of 30-50%. When the electrode material for a vacuum circuit breaker is produced, the powders are mixed, then the powder mixture is compression molded into a compression molded compact, and then the compression molded compact is sintered in the solid phase in a non-oxidizing atmosphere at a temperature not higher than the melting point of Cu, thereby obtaining a solid phase sintered body.</p> |
