摘要:
An electrode for a vacuum circuit breaker provided with a connecting portion made of a material having the same resistivity as the arc running face portions across the corresponding arc guiding channel at the outer circumferential end thereof, wherein when the outer diameter of the connecting portion is D.sub.1 and the inner diameter of the connecting portion is D.sub.2, the width of the connecting portion is designed so that the ratio D.sub.2 /D.sub.1 is in a range of more than 0.9 and less than 1.0. An arc generated between the electrodes is magnetically driven over the arc running face portions via the connecting portion so that the current interrupting capacity of the electrode is increased and the size and weight of the electrode are reduced.

A manufacturing method for erbium doped silica, having a soot formation process, in which a silica glass soot is deposited on a seed rod for forming a soot preform in a porous state on the seed rod, a dopant impregnation process, wherein the soot preform is impregnated with at least an erbium compound, and a preform formation process, wherein this soot preform impregnated with a dopant is heated and rendered transparent. The dopant impregnation process is provided with an operation in which the soot preform obtained in the soot formation process is dipped in a solution containing an erbium compound, an aluminum compound, and a phosphorus compound; this is then desiccated, and soot preform which is impregnated with the erbium compound, the aluminum compound, and the phosphorus compound is obtained.
摘要:
A vacuum interrupter of parallel magnetic field electrode type comprising a pair of separatable arc electrodes disposed within a vacuum vessel, with each being provided on its back side with a conductive rod extending outwardly of the vacuum vessel. Coil electrodes are electrically connected between the associated arc electrode and rod for applying parallel magnetic fields to arc, and slits are formed in the arc electrodes for suppressing eddy currents of the arc electrodes resulting from the parallel fields. A reinforcement member of an electric conductivity higher than a main surface portion of the arc electrode is provided on the back side of the arc electrode opposite to said main surface portion so that the resulting arc current flows uniformly through the reinforcement member so that a higher interruption efficiency can be obtained for the vacuum interrupter.
