Definitions

  • the present invention relates to interrupter switch and transformer combinations used in power distribution systems and, more particularly, to the combination of a magnetically actuated vacuum interrupter switch and an oil-filled distribution transformer, the switch being for controlling power to the transformer or the loop connection through the transformer.
  • the apparatus includes a housing formed from insulating material and having a mounting flange formed along the exterior of the housing. The flange is located so that the housing extends away from the mounting side and the upper side of the flange.
  • An electrical current interrupter having electrical input and output ends, is positioned in the housing so that a portion lies within the portion of the housing extending away from the flange mounting side.
  • An actuator is mechanically connected to the interrupter to provide the mechanical actuation required to interrupt the current flow between the input and output ends of the interrupter.
  • the interrupter is either a vacuum interrupter or an interrupter filled with an insulating fluid such as SF 6 gas. It is also preferred for the actuator to be a magnetic actuator.
  • the housing comprises an arm member and a base member, preferably integrally formed.
  • a conductor is connected to the electrical output of the interrupter. It is especially preferred for the base member to be molded around a portion of the conductor. It is also preferred for a current sensor, such as a current transformer, to be positioned proximate the conductor for sensing the current flowing there through.
  • a flexible conductor prefferably electrically connected between the output end of the interrupter and the conductor.
  • an insulating rod is mechanically interconnected between the actuator and the output end of the interrupter.

  • interrupter 16 include an electrical input end 16a and an electrical output end 16b.
  • output end 16b will be an electrically conductive rod that extends into interrupter 16 and is caused by operation of actuator 12 to either make contact or break contact with a second rod forming a portion of electrical input 16a.
  • the opened or closed state of interrupter 16 will, in turn, either permit or interrupt the flow of current from a source (not shown).
  • the current path is from interrupter 16 through flexible conductor 30 and conductor 19 to bushing connector 22.
  • the flexible current path connector 30, of any suitable contemporary design, is included for permitting current flow in the presence of the axial movement of rod 14, i.e., the flexibility of connector 30 permits its mechanical attachment to rod 14 and its electrical attachment to the conductor (shown in Figs., 1, 2, 4 and 5) extending from actuator 16.
  • the interrupter and actuator are encapsulated in arm 18 and base 20, each being formed from solid dielectric material, preferably urethane, epoxy or other known electrically insulating material.

It is noted that since rod 14 will exhibit axial movement and since flexible connector 30 will flex laterally, chambers of a size sufficient to permit such movement are formed in arm 18 and base 20.
  • a flange or mounting pad 28 is formed around a portion of base 20 and arm 18. As described below, flange 28 serves to mount device 10 onto another structure such as a container filled with insulating oil.

Abstract

L'invention concerne un appareil (10) permettant de couper le courant dans un système de distribution d'électricité utilisé avec une enveloppe contenant un fluide isolant. L'appareil (10) comprend un boîtier (20) formé d'un matériau isolant et d'une bride de montage (28) placée le long de l'extérieur du boîtier (20). La bride (28) est disposée de manière que le boîtier s'étende en s'éloignant du côté de montage et du côté supérieur de la bride. Un interrupteur de courant électrique (16), à extrémités électriques d'entrée et de sortie (16a, 16b), est logé dans le boîtier (20) de sorte qu'une partie se trouve dans la partie du boîtier s'éloignant du côté de montage du bride. Un actionneur (12) est relié mécaniquement à l'interrupteur (16) pour assurer un actionnement mécanique nécessaire pour couper le courant entre les extrémités d'entrée et de sortie de l'interrupteur. Lorsque la bride (28) est fixée à l'enveloppe, la partie du boîtier s'éloignant du côté de montage de la bride s'étend dans le fluide contenu dans l'enveloppe.
