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.
Claims15
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 electrical 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 electrical interrupter.
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 via a vacuum slot formed in a support bay;
- separating discharged particles from the flowing fluid;
- and
- capturing the discharged particles.
A particle extraction system, wherein a support bay is configured to hold a plurality of electrical interrupters that includes an electrical interrupter,
- wherein an actuator system is operable to cycle the plurality of electrical interrupters to release particles,
- wherein a fluid source is in fluid communication with internal flowpaths formed within the plurality of electrical interrupters, wherein flowing fluid from the fluid source is operable to entrain released particles therewith, and
- wherein a vacuum slot is operable to receive the flowing fluid and entrained particles egressed from the plurality of electrical interrupters.
