Abstract
A current interrupting switch for power distribution systems comprising an outer case and a plurality of vacuum interrupter bottle switches positioned in the case.
Claims9
A vacuum interrupter switch for a power distribution system comprising:
- an enclosure capable of passing through a circular opening having a diameter of approximately 30 inches and substantially free of oil and SF6 gas within its interior;
- a first pair of power bushings extending from an upper region of a first side of the enclosure;
- a second pair of power bushings extending from a lower region of a second side of the enclosure;
- a plurality of vacuum interrupter bottle switches positioned within the enclosure, each of said vacuum interrupter bottle switches having a movable contact and a stationary contact;
- a bus positioned within the enclosure and electrically connected to one of said contacts of each of the plurality of vacuum interrupter bottle switches,
- the stationary and movable contacts of each vacuum interrupter bottle switch being positioned in circuit between the bus and a respective power pushing so that electrical coupling of its contacts electrically couples the power bushing to the bus via the vacuum interrupter bottle switch, and electrical decoupling of its contacts results in no electrical coupling of the power bushing and bus by the vacuum interrupter bottle switch;
- and
- a plurality of operating mechanism assemblies coupled to the plurality of vacuum interrupter bottle switches for selectively electrically coupling and decoupling the contacts of selected interrupter bottle switches.
