Shutter system for a switchgear compartment and method of manipulating a shutter system

A shutter system for a switchgear compartment comprising:

• a fixed shutter defining a plurality of fixed shutter apertures;
• a moveable shutter defining a plurality of moveable shutter apertures, the moveable shutter comprising an open position and a closed position, wherein the plurality of moveable shutter apertures is aligned with the plurality of fixed shutter apertures in the open position, and wherein the plurality of moveable shutter apertures is misaligned with the plurality of fixed shutter apertures in the closed position;
• a pusher operatively coupled to a first side of the moveable shutter;
• a bell crank in operable communication with the moveable shutter;
• and
• a cam member operably coupled to at least one wall of a breaker compartment and comprising a cam shaft operatively coupled to the fixed shutter and the moveable shutter, the cam member having a cam track configured to guide the bell crank to translate the moveable shutter between the closed position and the open position.

A method of manipulating a shutter system for a switchgear compartment comprising:

• imparting a force on a pusher operatively coupled to a first side of a moveable shutter;
• rotating and translating a bell crank along a cam track of a cam shaft extending through the moveable shutter, the bell crank in operable communication with the moveable shutter;
• and
• translating the moveable shutter from a closed position to an open position upon rotation of the bell crank.
