TESLAC spit this out
Hello all
I just got my first x-former yesterday. It is an actown outputting 9000
v-at-30ma. Simply had to repace the pull switch and now it works great.
I downloaded Teslac and have been trying to figure out what I needed to
build a TC.
Here is what I came up using Teslac:
First of all I have a actown neon x-former with secondaries rated for
9000 volts -at- 30 ma. Yeah, at least now I have the transformer:)
1) For the capacitor if I use two 14" X 14" (overlap measurement) flat
plates seperated by a sheet of mica (I have not seen how difficult this
is going to be to get yet), I can get a rating of 56KV with a .04 in.
thickness. Does this seem right?
2) For the secondary I (and yes, randomly chose) chose a height of 20
inches, 6 inch diameter coil wound with 20 gauge wire. I plan on doing
this on pvc-type pipe. This is what I was given for calculations:
The number of turns is: 588.2353 closewound with .034 inch dia. wire
Secondary winding length is 20 inches
Secondary winding diameter is 6 inches
Rsonant freq. is approx. 423.5564 KHZ.
The required wire length is 923.5294 feet
The aspect ratio (H/D) is 3.333333
Reactance is 36491.33 ohms at 423.5564 KHZ.
The maximun unloaded Q is 146.6225 at 423.5564 KHZ.
The secondary inductance is approx. 13.71888 MILLIHENRY
The estimated loaded Q will be approx. 65.16554
The terminal capapticance should be large enough to
cause the resonant freq. to drop to approx. 296.4895 KHZ.
3) For the static gap, TESLAC asked for how many volts my transformer
is rated for and here is the response it gave:
WHAT IS YOUR TRANSFORMER R.M.S. SECONDARY VOLTAGE
? 9000
THIS SERIES GAP SYSTEM SHOULD BE BUILT WITH 8.0 GAPS
EACH GAP SHOULD BE SET AT APPROX. .025 INCH
AND COOLED BY AN AIR BLAST AT POWER LEVELS ABOVE 1 KILOWATT
What does it mean to have 8.0 gaps? How does a person go about making a
gap or if I need 8 of them, how do I make that?
4)This takes me to the primary coil. I decided to figure it out using
3/8" copper tubing, with spacing 3/8" turn spacing and 2 inches between
the secondary and the primary.
Here is the response for it:
YOU NEED 45.7 U.H. TO RESONATE AT 296.4895
KHZ.
THE INDUCTANCE AT TURN NUMBER 3 IS APPROX. 4.7
U.H.
THE INDUCTANCE AT TURN NUMBER 4 IS APPROX. 8.0
U.H.
THE INDUCTANCE AT TURN NUMBER 5 IS APPROX. 12.3
U.H.
THE INDUCTANCE AT TURN NUMBER 6 IS APPROX. 17.6
U.H.
THE INDUCTANCE AT TURN NUMBER 7 IS APPROX. 24.0
U.H.
THE INDUCTANCE AT TURN NUMBER 8 IS APPROX. 31.4
U.H.
THE INDUCTANCE AT TURN NUMBER 9 IS APPROX. 40.0
U.H.
THE INDUCTANCE AT TURN NUMBER 10 IS APPROX. 49.9
U.H.
THE PRIMARY INSIDE DIAMETER WILL BE 10
INCHES
THE PRIMARY OUTSIDE DIAMETER WILL BE 24.25
INCHES
IT WILL HAVE 10 TURNS OF .375 INCH
CONDUCTOR
THE TURN TO TURN SPACING WILL BE .375
INCH.
Ok, I realilze that there was alot to this post, but if any of you have
the time, could you please go over it and tell me where the design is
wrong or suggestions on what to do to make this thing work, I sure would
appreciate it!
