High voltage interrupter
First Claim
1. A circuit interrupter comprising:
- a housing having a first end and a second end, and including an internal cavity defined by an internal wall, said internal cavity including a space at said first end;
a vacuum interrupter disposed in said space, said vacuum interrupter having at least one movable contact for contacting at least one stationary contact;
a non-conductive operating rod extending through said cavity, and operable to move said at least one moveable contact; and
at least one baffle fixed to said operating rod and disposed in said cavity, said baffle increasing the through-air strike distance between said vacuum interrupter and second end of said housing over a straight line path from said vacuum interrupter to said second end of said housing.

Abstract
A circuit interrupter including a housing having an internal cavity. The internal cavity includes a space at a first end thereof, and includes an internal wall extending from the space to a second end of the housing. A vacuum interrupter is disposed in the space. The vacuum interrupter has at least one movable contact for contacting at least one stationary contact. An operating rod extends through the cavity, and is operable to move the moveable contact. At least one baffle is fixed to the operating rod, and disposed in the cavity. In a preferred embodiment, at least one step is formed in the wall. The step separates a first internal wall section from a second internal wall section, and the first internal wall section is closer to the space than the second internal wall section.

18. A circuit interrupter comprising:
-
a housing having a first end and a second end, and including an internal cavity defined by an internal wall, said internal cavity including a space at said first end;
a vacuum interrupter disposed in said space, said vacuum interrupter having at least one movable contact for contacting at least one stationary contact;
at least one step formed in said wall, said at least one step separating a first internal wall section from a second internal wall section, said first internal wall section being closer to said space than the second internal wall section, said step having an inner edge joined to said first internal wall section and an outer edge joined to said second internal wall section;
a non-conductive operating rod extending through said cavity, and operable to move said at least one moveable contact; and
at least one baffle fixed to said operating rod; and
disposed in said cavity, said baffle extending radially from said operating rod toward said second internal wall section past said step inner edge, and increasing the through-air strike distance between said vacuum interrupter and said second end of said housing over a straight line path from said vacuum interrupter to said second end of said housing.- View Dependent Claims (19, 20, 21, 22, 23, 24, 25)
