    摘要: There are provided an energy-storing unit with a forcing mechanism and an on-load tap changing device provided with the same which employ an inexpensive and simple structure and which can suppress a loading torque to operate stably. A forcing mechanism built in an energy-storing unit includes a protrusion 8, a bearing 9, and a loading cam 17. Among those components, the protrusion 8 is attached to the bottom face of an eccentric cam 2, and the bearing 9 is attached to the tip of the protrusion 8. The loading cam 17 is an isosceles triangle having a vertex that is substantially 90 degrees, and is attached to the top face of an energy-storing case 5. The loading cam 17 becoming in contact with the bearing 9 causes a crank 6 to rotate through the energy-storing case 5, and feeds a catch 7 to a standby position.

    摘要: A linear actuating earthing switch configuration that moves movable contacts using linear motion in a single axis. The earthing switch includes a frame with a rail on a slide wall. A sliding carriage slides on the rail in a linear direction, the sliding carriage including a plurality of movable contacts. A spring surrounding a linear shaft provides a linear expansion force between the frame and the sliding carriage when the earthing switch is in an open position.

    摘要: An emergency opening device suitable for manually opening a switching device comprises:
    - striking rod means (5) for transmitting an opening-striking-force to an electromagnetic actuator which is operatively connected to electrical contacts of said switching device;
    - a guiding-housing (2) suitable for being placed on an external portion of a casing in which the switching device is housed, the guiding-housing being configured for slidably housing and guiding, along an operating direction, the striking rod means,
    - energy-storing-propelling-means(13) for propelling the striking rod means upon an external-triggering-command of an operator in order to impart the opening-striking-force to the electromagnetic actuator.
    The energy-storing-propelling-means are configured for imparting to the striking rod means along the operating direction a rectilinear snap movement having at least a kinematic parameter which is independent from the external-triggering-command.

    摘要: A spring assembly (200) is provided for a yoke assembly (100) of an electrical switching apparatus including a housing (4), separable contacts (8) enclosed by the housing, and an operating mechanism (10) structured to open and close the separable contacts. The operating mechanism includes a pole shaft (12). The yoke assembly is coupled to the pole shaft and is movable among first and second positions corresponding to the separable contacts being closed and open, respectively. The spring assembly includes a number of first springs (202) having a first spring rate and being coupled to the yoke assembly, and a number of second springs (206) having a second spring rate and being coupled to the yoke assembly. The second spring rate is different than the first spring rate. The number of first springs and the number of second springs bias the yoke assembly toward the second position.
