  • Patent number: 11756755
    Abstract: A dual energy storage operating mechanism of an isolating switch is provided. A first energy storage mechanism and a second energy storage mechanism are provided between an input wheel and a housing and between the input wheel and an output wheel or a first output shaft, respectively. The output wheel is provided with a limiting mechanism. The limiting mechanism forms a locking effect on the output wheel when the first energy storage mechanism stores energy, thereby enabling the second energy storage mechanism to store energy at the same time. When the first energy storage mechanism starts to release energy, the locking effect of the limiting mechanism is released, so that the output wheel and the first output shaft can rotate, and the first energy storage mechanism and the second energy storage mechanism release energy at the same time, forming a dual energy storage boosting effect.

  • Patent number: 11107647
    Abstract: A solid state circuit interrupter provides structures which can manually move an isolation switch of a pole from the ON state to the OFF state without the use of auxiliary power but that advantageously additionally provides an interlock apparatus that avoids manually moving the isolation switch from the ON state to the OFF state until certain conditions exist. One such condition is to ensure that some action is taken, such as by switching a physical interlock between one state and another state. Such a change in state of the physical interlock might additionally result in a change in state of an electronic interlock that would resist the solid state switch being moved to its ON state while the isolation switch is capable of being manually switched to its OFF state. The physical interlock might additionally resist the isolation switch from being manually switched into its ON state.

    Abstract: An actuator assembly for remote actuation of control panel components in an environment that restricts human access is contemplated. The actuator assembly includes one or more remotely controllable linear drive mechanisms for imparting a rotation motion on one or more cams to remotely press a control panel component such as a button or switch. While disengaged, the cams are rotated to a position where they minimally obstruct an operator's view. The actuator assembly also allows the force and throw of actuation to be accurately controlled.

  • Publication number: 20120175228
    Abstract: A safety switch is improved by the feature of staying in an open position in the event of breakage of a working rod or breakage or dropout of an operation portion and having a simple structure facilitating size reduction. Even if a rotary shaft is released from a supported state in an operation portion because an operating force of an operation or the number of operations of extracting an actuator from the operation portion exceeds a breakage tolerance, a working rod is permitted to move in an urging direction of a coil spring and is assuredly moved to the operation portion. Therefore, a switch can be assuredly set to an open position and, hence, the safety switch can achieve the safety improvement.

  • Publication number: 20120168287
    Abstract: A switching assembly having an interlock device for a selector switch is provided. The interlock device includes a flapper member rotatably coupled to a base member. The flapper member has an aperture disposed proximate to an aperture of a panel such that the selector switch extends through the apertures. The flapper member further includes an indented region and has a first operational position proximate to the panel and a second operational position disposed outwardly from the panel. When an arm portion of the selector switch is disposed within the indented region of the flapper member at the second rotational position and the flapper member is rotated to the second operational position, then the arm portion cannot be rotated outside of the indented region.

  • Publication number: 20120160639
    Abstract: A transfer switch mountable in a standard electrical panel connects either a utility supply or an auxiliary supply to an electrical system. An internal mechanical interlock prevents both the utility supply and the auxiliary supply from simultaneously being connected to the system. The transfer switch may utilize either a rocker-style or a blade style switch. A light-emitting diode provides an indication of whether the utility supply is connected to and a voltage is present at the utility supply terminal. A power meter provides an indication of the magnitude of power drawn from the auxiliary supply when the auxiliary supply is connected to the load.

  • Patent number: 8203088
    Abstract: A close latch interlock assembly is provided for an electrical switching apparatus, such as a circuit breaker, which includes a stored energy mechanism, such as a closing spring. The close latch interlock assembly includes a close D-shaft pivotable between a latched and unlatched positions corresponding to the closing spring being chargeable and discharged, respectively. An actuator is movable between an unactuated position corresponding to the close D-shaft being disposed in the latched position, and an actuated position corresponding to the close D-shaft being movable toward the unlatched position. A release member cooperates with the actuator and is pivotably coupled to the first end of a transfer link. The second end of the transfer link extends toward the close D-shaft. When the actuator is moved toward the actuated position, it moves the release member, thereby moving the transfer link and pivoting the close D-shaft toward the unlatched position.

  • Patent number: 8115127
    Abstract: The present invention relates generally to a rotary handle. More particularly, the invention encompasses a deliberate action rotary handle. The invention further includes an extended drive-plate deliberate action rotary handle, such that to turn on a component, such as, a circuit breaker, requires a deliberate manual action by the user. If a deliberate action is not taken by a user but the handle is accidentally pushed then the handle does not engage with a drive shaft and the handle moves to an outer edge of a drive plate thus preventing the engagement of the handle with the other components to turn on the component.

  • Publication number: 20110079494
    Abstract: A rechargeable battery includes a housing and a plurality of electrochemical cells that are electrically connected to one another and form a high-voltage circuit. A high-voltage socket on the housing comprises two electrical poles, and the high-voltage socket is configured to be connected to a high-voltage plug. A catch on the high-voltage socket is configured to interact with a locking element on the high-voltage plug for locking the high-voltage plug to the high-voltage socket. A low-voltage circuit includes an integrated contactor for interrupting and closing the high-voltage circuit. A service plug connector is used for closing and disconnecting the low-voltage circuit; the service plug connector interacts with the high-voltage plug such that the high-voltage plug cannot be withdrawn from the high-voltage socket until the service plug connector has been removed from the rechargeable battery, and is configured to block the locking element on the high-voltage plug of the rechargeable battery.
