Re: Magnetic quenched gaps


        Reply to:   RE>Magnetic quenched gaps

Has anyone experimented with rotary gap electrode Geometry vs Quench ?

Could electrode geometry be designed such that extinction is naturally encouraged  to ocurr after the first node -- make them longer (to retain xsectArea for current and heat) and thin to present conductor for a short arc time at optimum cycle times ? (or perhaps in conjunction with air/magnetic quenching?) 
A thought from Dale.

Hmmm.."what if"  a synchroized motor driving a piston compressor?
I guess the inertial lag of the air column would prevent it
accellerating supersonic......or would the motor need to be
extremely large to stay synchronous with such a load? Just food for
thought.
