摘要： PROBLEM TO BE SOLVED: To improve energy efficiency by varying an energizing method of electromagnetic coil based on a condition of load side. SOLUTION: A mover 2 of the actuator includes a plunger member 21 and a handguard member 22, and is arranged to be reciprocated from a latch location to a latch release location within a stator 1. A first electromagnetic coil 31 has enough electromagnetic force so that the mover 2 stated in a latch release condition can be made to be a latch condition at the time of energizing. A permanent magnet 4 absorbs the handguard member 22 of the mover 2 stated in the latch condition by the electromagnetic force of the first electromagnetic coil 31, and has an absorbing force enough to keep the latch condition at the time of non-energizing of the first electromagnetic coil 31. A second electromagnetic coil 32 reduces a magnetic flux of the permanent magnet 4 at the time of the energizing, and can change the mover 2 from the latch condition to the latch release condition.

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.
