    • A tank for a circuit breaker has a body defining an interior volume and having opposing ends. An flange is at each end of the body with the flanges defining a central longitudinal axis of the body. The body has an internal surface defining a top portion of the tank disposed substantially above the axis and defining a bottom portion of the tank disposed substantially below the axis. The top portion is spaced from the axis as defined by at least a first radius from the axis. The bottom portion is spaced from the axis as defined by at least a second radius from axis. The second radius is greater than the first radius so as to reduce an electric field intensity on the bottom portion of the body and thus reduce effects of foreign particles within the interior volume, regardless of phase rotation.
    • 用于断路器的容器具有限定内部容积并具有相对端的主体。 凸缘位于主体的每个端部处,凸缘限定主体的中心纵向轴线。 主体具有内表面,其限定了基本上在轴线上方布置的罐的顶部,并且限定了基本上位于轴线下方布置的罐的底部。 顶部与轴线间隔开,至少距轴线的第一半径所限定。 底部与轴线间隔开,至少距离轴线的第二半径所限定。 第二半径大于第一半径,以便减小身体底部的电场强度,从而减少外部颗粒在内部体积内的影响,而不管相位旋转如何。

    • A MOC operator structure for a circuit breaker includes linkage structure coupled between the operating mechanism and an interface structure. An armature is associated with the linkage structure. Permanent magnet structure is associated with the circuit breaker and is disposed generally adjacent to the armature. Wherein, when the operating mechanism is coupled with the linkage structure and the operating mechanism moves in a first direction, a portion of the linkage structure moves in a first direction and moves the MOC operator structure to an open position, with the armature being magnetically engaged with permanent magnet structure to maintain the MOC operator structure in the open position. When the portion of the operating mechanism moves in a second direction, the portion of the linkage structure moves in a second direction and moves the MOC operator structure to a closed position, with the armature magnetically disengaging from the permanent magnet structure.
    • 用于断路器的MOC操作器结构包括连接在操作机构和接口结构之间的连接结构。 电枢与联动结构相关联。 永磁体结构与断路器相关联并且大致相邻于电枢设置。 其中,当所述操作机构与所述联动结构联接并且所述操作机构沿第一方向移动时,所述联动结构的一部分在第一方向上移动并且将所述MOC操作者结构移动到打开位置,所述衔铁被磁性接合 具有永磁体结构,以将MOC操作员结构保持在打开位置。 当操作机构的部分沿第二方向移动时,连杆结构的部分沿第二方向移动,并且将MOC操作器结构移动到关闭位置,电枢与永磁体结构磁力分离。
