Abstract
A center bolt LBOR switch 12 comprising a support ring 12-4 and a center bolt or threaded boss 12-2, and a nut 12-3 for securing the switch 12 to a transformer tank wall is disclosed. The disclosed invention allows a switch or other device to be mounted to the wall of a transformer tank without welding and without distorting the tank wall.
Claims12
A support mechanism for mounting a mechanical load to a transformer tank wall, comprising:
- a. a mechanical load mounted to extend from a first side through an aperture in said tank wall to a second side, wherein a downward force (W) is exerted on said load at said second side of said wall, said load comprising a threaded boss with a portion thereof extending through the aperture in said tank wall;
- b. a nut in threaded engagement with said threaded boss and securing said load to said tank wall;
- and,
- c. a support member coupled to said load and said second side of said wall, and disposed in spaced apart surrounding relationship to the aperture and the portion of said load extending through said tank wall;
- whereby said downward force (W) is balanced by a force (F) acting through said support member.

Transformer apparatus comprising:
- a. a transformer tank having a wall;
- b. a transformer core/coil assembly mounted within said transformer tank;
- c. a mechanical load mounted to extend from a first side through an aperture in said tank wall to a second side, wherein a downward force (W) is exerted on said load at said second side of said wall, said load comprising a threaded boss with a portion thereof extending through the aperture in said tank wall;
- d. a nut in threaded engagement with said threaded boss and securing said load to said tank wall;
- and,
- e. a support member coupled to said load and said second side of said wall, and disposed in spaced apart relationship to the aperture and the portion of said load extending through said tank wall;
- whereby said downward force (W) is balanced by a force (F) acting through said support member.
