Abstract
A particle extraction system for an electrical interrupter is disclosed in the present application. The particle extraction system includes a support bay configured to hold an electrical interrupter in position during a particle extraction event. An actuator system is operable for cycling the interrupter to dislodge and release foreign particles internal to the interrupter. A fluid source and pumping system is in fluid communication with at least one internal flowpath within the interrupter to entrain and transport the released particle from the interrupter. A vacuum slot is operable for receiving a fluid flow with entrained particles and transporting the particles to a particle capture device.
