  • Circuit switching mechanism and charging system therefor
    Patent number: 5504289
    Abstract: A circuit switching mechanism for use in a high voltage circuit breaker is disclosed. The disclosed mechanism comprises a charging system (12); trip latch mechanism (14); an opening spring (16); a closing spring (18) positioned coaxially with the opening spring; a support structure (22) supporting the open and closing springs; and a first rod member (24) operatively associated with a circuit interrupter, the first rod member being operatively coupled to the open and closing springs such that discharging of the opening spring effects the movement of the first rod member in a first direction and discharging of the closing spring effects the movement of the first rod member in a second direction.

  • Slip-through mounting structure for circuit interrupter
    Patent number: 5495084
    Abstract: The movable contact of a puffer interrupter contains a movable conductive tubular sleeve which is electrically connected to and is slidably mounted within a hollow conductive adapter which is supported from the end of a bushing insulator. An insulation rod flexibly connects the adapter to the housing. A pair of flexible rods connect the end of the interrupter to the end of the housing. The puffer interrupter is mounted within a dead tank housing.

  • Mechanical guidance system for switcher interrupter and method for assembling the same
    Patent number: 5483210
    Abstract: A guidance system for an interrupter switcher comprising a first guide positioned in between the contact support and the movable contact system of the interrupter, and a second guide inserted into the stationary contact system of the interrupter. According to the invention the second guide is capable of receiving the nozzle of the movable contact system. An interrupter with the guidance system is assembled by positioning the first guide between the contact support and the movable contact system, positioning the second guide within the stationary contact system, inserting the nozzle of the movable contact system into the second guide, and mounting the stationary contact system in the interrupter housing. The assembly of an interrupter with a guidance system results in a self-adjusting switcher interrupter capable of maintaining a stable alignment between the interrupter's movable and stationary contacts while opening and closing the interrupter.
