Subject: Cylindrical Static Gap- Help Needed.
I have built a R.Q. style cylindrical gap from 4" PVC pipe and seven 1"
dia x 2.5" dia copper pipe segments gapped at 0.030". This gap works
okay, but I suspect that there is room for improvement in my
implementation.
I would like to increase the number of electrodes past 7, while keeping
the distance the same. This would require me to space the pipe segments
less than about 0.020" apart- how do I do this? My current gaps were set
using 30mil LDPE as spacers. Do I just need thiner spacers, like copper
flashing pieces maybe? I have noticed that at 0.030", the electrodes
tend to have a single arc between them, whereas at 0.024" and less, the
arc spreads out over the length of the pipe segments and greating
improves the quenching.
Also, I am using a 4" diameter 108 CFM fan. Would switching to a 230 CFM
fan (or greater) show much improvement at my 9kV 1-2kVA operating range?
Some people are using heavy duty vacuum cleaner blowers, aren't they? I
have also blocked the center area of the gap with a tube, to force all of
the current 108CFM across the electrodes.
Any suggestions would be much appreciated.
