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.
Claims11
A particle extraction system comprising:
- a support bay configured to hold an electrical interrupter;
- an actuator system operable for cycling the electrical interrupter to release particles;
- a fluid source in fluid communication with internal flowpaths formed within the interrupter, wherein flowing fluid from the fluid source is operable to entrain released particles therewith;
- and a vacuum slot operable for receiving the flowing fluid and the entrained particles egressed from the interrupter.
-14. (canceled)
A method comprising:
- cycling a component in an electrical interrupter between first and second positions;
- dislodging and releasing particles within the electrical interrupter during the cycling;
- entraining the released particles in a flowing fluid;
- discharging the flowing fluid and entrained particles from the electrical interrupter;
- separating the discharged particles from the flowing fluid;
- and capturing the discharged particles.
