    • A magnetic flux density B which is 0.75-0.9 times as dense as that of the axial magnetic flux density (Bcr) at which the arc voltage between electrodes becomes the minimum with respect to each breaking current is impressed upon the center of an electrode and the axial magnetic flux density is monotonously increased from the center toward the periphery of the electrode. The radial position upon which the axial magnetic flux density (Bcr) at which the arc voltage becomes the minimum Vmin is in the range of 20-40 % of the radius of the electrode. The axial magnetic flux density is further increased from this range monotonously toward the outside so that the density becomes the maximum (Bp) outside the 70 % radius of the electrode. The maximum value (Bp) is 1.4-2.4 times as dense that of the magnetic flux density (Bct) at the center of the electrode. The distribution of the axial magnetic flux density in the circumferential direction of the electrode at a radial position in the peripheral area of the electrode at which the axial magnetic flux density becomes the maximum is changed unevenly. The axial direction magnetic flux density in the circumferential direction is distributed so that at least two peaks appear over the full circumference. The maximum value (Bmax) and minimum value (Bmin) of the circumferential magnetic flux density distribution are 1.4-2.4 times as dense as that of the axial magnetic flux density (Bct) at the central part of the electrode.
    • 与电极之间的电弧电压相对于每个断开电流成为最小的轴向磁通密度(Bcr)的0.75〜0.9倍的磁通密度B施加在电极的中心,并且 轴向磁通密度从电极的中心朝向周边单调增加。 电弧电压变为最小Vmin的轴向磁通密度(Bcr)的径向位置在电极半径的20-40%的范围内。 轴向磁通密度从该范围进一步向外扩展,使得密度在电极的70%半径之外成为最大值(Bp)。 最大值(Bp)是电极中心处磁通密度(Bct)密度的1.4-2.4倍。 在轴向磁通密度变为最大的电极的周边区域的径向位置处的电极周向的轴向磁通密度的分布不均匀地变化。 沿圆周方向的轴向磁通密度分布,使得在整个圆周上出现至少两个峰。 圆周磁通密度分布的最大值(Bmax)和最小值(Bmin)是电极中心部分的轴向磁通密度(Bct)的最大值(Bmax)和最小值(Bmin)的1.4-2.4倍。

    • A contact arrangement is proposed which is a considerable improvement over the state of the art for generating a magnetic field in vacuum switching tubes, in which gaps, especially in the bottom and then in the wall of a cup-shaped support form winding sections generating magnetic fields: first gaps, e.g. according to (6), run along the inside of the cup in the cup bottom (3). Second gaps (4) extending into the cup wall (4), e.g. according to (7e), adjoin. Consequently there is a basic winding shape, the design of which can be refined, e.g. according to (9). The cup bottom connects such winding sections superficially with the power connector (2). With an equal-level and especially flat connection, according to the arrangement of flow conducting gaps, e.g. acccording to (15), in the cup bottom, there is also an azimuthal flow to the winding sections (9), which reinforces their magnetic field generation. The basic winding shape can already peripherally overlap the prior cup bottom outlet regions. Third and fourth gaps adjoining the second gap in the cup wall extend the basic winding shape, thus also producing an axial overlap. An axial overlap in the basic shape of the winding sections provides a two layer annular winding in the end effect with the very minimum height provided by the design and the maximum magnetisation efficiency.

    • A fixed electrode 10 and a movable electrode have coil electrodes formed of plural coil portions installed at both contacts and on a rear surface side in a divided manner in a circumferential direction along peripheries of the contacts such that a longitudinal field is generated in a direction in which the fixed contact and the movable contact come close to and move apart from each other. Protruding portions joined to the contacts are provided to tip ends of the respective coil portions to form joint portions to the respective contacts. A current to be flowed is controlled by changing resistance values between the contacts and the coil electrodes for each joint portion.

    • A vacuum interrupter for reducing contact resistance and thereby reducing electromagnetic repulsive force between electrodes, is obtained. The vacuum interrupter includes a stationary electrode rod fixedly placed on one closed end of a cylindrical evacuated envelope closed at both ends thereof; a movable electrode rod movably placed on the other closed end; disc shaped contacts placed on opposing ends of the electrode rods; and reinforcement members for reinforcing the contact placed between each electrode rod and the associated contact. In such a configuration, a coefficient of linear expansion of the reinforcement member differs from that of the contact, and the reinforcement member and the associated contact are jointed by soldering at a plurality of opposing parts thereof.
