摘要： PROBLEM TO BE SOLVED: To provide a contact point material for vacuum valves which can improve the smooth state of contact surfaces, therefor, which is superior in withstand voltage characteristics, as well as in current-cutting properties, and also to provide a vacuum valve that uses the contact point material, a manufacturing method of the vacuum valve, and thereby, a low-surge vacuum breaker having superior characteristics.
SOLUTION: A contact material for vacuum valves is made by having 0.02-1.0% by mass of Ag
2 Te contained in an Ag-WC based contact material, and the Ag
2 Te exists in a form of a coat layer or particles having sizes (diameters or thicknesses) of 0.01-0.2 um on an interface between Ag and WC, consisting of the matrix of contact points 13a, 13b, as well as in a form of an Ag
2 Te precipitate that is precipitated in Ag constituting the matrix. When contact points 13a, 13b are used as the contact points of vacuum valves, an Ag
2 Te coat, which is deposited slightly; when heated by current switching or current breaking, covers the contact surfaces to maintain smoothness, and thus, for improving the withstand voltage characteristics. By including Ag
2 Te in an Ag-WC base contact point material at the predetermined rate, smoothness on contact points is maintained, even after current switching or current breaking has been processed, and then the withstand voltage characteristics can be improved. Accordingly, a vacuum breaker using the contact point material can improve withstand voltage characteristics to achieve high reliability, in keeping the same superior current-cutting characteristics as the conventional Ag-WC base contact points have.

摘要： PROBLEM TO BE SOLVED: To provide a manufacturing method for a contact for a vacuum bulb capable of manufacturing the contact having excellent voltage endurance characteristics and a current-interruption property.
SOLUTION: Cu powder and Cr powder are mixed (step 1), and a Cu and Cr mixed powder compact is obtained (process 2) by pressing the mixed powder. Then, the mixed powder compact is set in an arc-melting apparatus, and a Cu infiltrant is superposed on the compact and melted to infiltrate into the Cu and Cr mixed powder compact (step 3). After arc energy is increased if necessary to simultaneously melt Cu and Cr on the surface of an infiltrated body, the arc is stopped and the infiltrated body is rapidly cooled to solidify (step 4). If required, aging treatment is subsequently performed to precipitate solid-solution Cr. From the infiltrated body removed from the arc-melting apparatus, a contact is processed and removed (step 5). The contact containing little gas and having excellent voltage endurance characteristics and a current-interruption property is manufactured through these steps.
