Abstract
A locking arrangement for use on a draw-out mechanism mounted on a circuit breaker within a switchgear cabinet includes a fixed side plate arranged for mounting within switchgear cabinet, a mobile side plate includes a pin extending threrefrom, the mobile side plate arranged to move the circuit breaker in cooperation therewith and an obstructor plate pivotally mounted to the fixed sideplate, the obstructor plate having a slot and a notch extending from the slot, the pin traversing the slot to allow the mobile side plate to move relative to the fixed side plate.
Claims36
A locking arrangement suitable for use with a draw-out mechanism mounted on a circuit breaker within a switchgear cabinet, the locking arrangement comprising:
- a fixed side plate arranged for mounting within switchgear cabinet;
- a mobile side plate, said mobile side plate includes a first pin extending therefrom, said mobile side plate arranged to move the circuit breaker in cooperation therewith;
- an obstructor plate pivotally mounted to said fixed sideplate, said obstructor plate having a slot and a notch extending from said slot, said first pin traverses said slot to allow said mobile side plate to move relative to said fixed side plate;
- wherein rotation of said obstructor plate positions said first pin in said notch to prevent said movable side plate from moving relative to said fixed side plate.
The locking arrangement of claim I further comprising:
- a locking slide slidably engaged to said fixed side plate and pivotally attached to said obstructor plate, said locking slide having a locking hole disposed therein, said locking hole arranged to accept a lock to prevent movement of said mobile side plate relative to said fixed side plate.
A draw-out mechanism for mounting a circuit breaker within a switchgear cabinet, the draw-out mechanism comprising:
- a cover having an access hole;
- a fixed side plate arranged for mounting within the switchgear cabinet;
- a mobile side plate, said mobile side plate includes a first pin extending therefrom, said mobile side plate arranged to move the circuit breaker in cooperation therewith;
- a crank slidably connected to said mobile side plate, said crank protrudes from said access hole;
- an obstructor plate pivotally mounted to said fixed sideplate, said obstructor plate having a slot and a notch extending from said slot, said first pin traversing said slot to allow said mobile side plate to move relative to said fixed side plate;
- wherein rotation of said crank rotates said obstructor plate and positions said first pin in said notch to prevent said movable side plate from moving relative to said fixed side plate.
