307200000000 V DC ! sound fun?

Well i saw these on ebay and if you do the math and connect these all up then you would get in the UK several million volts...

http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&Item=160253043622&Category=4665

Its a step up/ down transformer going from 240V to 12V DC each one...

so that would be a factor of 20... and we would have 7... so if we were to put in 240V instead of the 12V you woudl get 4800V keep doing this for the next 6 transformers and you get:

240 V X (20^7)
=
307 200 000 000V

Its theoretically possible but there woudl be diminishign current each time so lots of volts no amps (which is a good thing). And they are ~90% efficient do maybe it would be slightly less.

Is this possible? if so I'm getting them lol!
 





Re:  307200000000 V DC ! sound fun?

you would have real bad insulation problems with voltages like that. the insulation on them would not cope and you would have arcing.
 
Re:  307200000000 V DC ! sound fun?

As I said it is a theory- distance between contacts is just over 1cm capable of insulating 10000V so i woudl deal with that and at those voltages it would arc across long distances but otherwise is it possible?
 
Re:  307200000000 V DC ! sound fun?

the insulation on the wire thats wound around the core would just melt down and burn up. it would look cool though.
 
Re:  307200000000 V DC ! sound fun?

theres no current so that wouldnt happen no melting...

im not sure what the resistance of rubber is though but it may fail to insulate it- thats true
 
Re:  307200000000 V DC ! sound fun?

the secondary windings in those transformers wouldn't be able to handle the current of running at 240v, it would just blow up
 
Re:  307200000000 V DC ! sound fun?

I'm quite sure that's an AC transformer, not a DC component.

Yep..
I got few similar transformers from disassembled electronics :) Maybe I should try and take a video lol. Well, not really, all it would do is lame fireworks and pop out the fuses in my house (and possibly electrocute me).
 
Re:  307200000000 V DC ! sound fun?

no I'm doing physics and I'm 100% sure transformers only work with AC current. Thats why our houses use AC not DC cos it ban be stepped up for pylons and then down again for home- DC cant...
 
Re:  307200000000 V DC ! sound fun?

well that would never work.

the insulation on the coils could never stand up to that kind of voltage... once you've seen a corona on those thick silcone wires they use for hv applications (at under a million volts!) then you'll understand what's needed when dealing with such massive amounts of electrons... look at the size of the secondary winding on a tesla coil to get an idea.

Anyways, if you want to DIY a few million volts for cheap, look into making a Van de Graff generator. If you can salvage a big metal ball or a couple of colanders, an electric motor and a belt, you can build yourself millions of volts worth of static electricity capable of lighting florescent bulbs at a distance.

already have access to a vander graff- they are really overrated.

Its about 2 feet tall and only works on dry days with low humidity and will generate a maximum of 100000V...

Only two feet tall? Well that's your problem right there. You need a real Van de Graaff generator http://en.wikipedia.org/wiki/Image:BosMusOSci_VanDGLightening.jpg <---those two spheres are about 15ft in diameter each, and it can reach 2 million volts. They have been built that could go over 25 million volts. I'm sure you could do better building one on your own than that measly 2 feet tall contraption.

Seriously, get one a little bigger. I've played with one about 7 feel tall, and it really is a lot of fun.
 
Re:  307200000000 V DC ! sound fun?

what i was trying to get at is that the insulation on the windings will just arc and short out. it doesn't matter what the current is, it will still arc and leak current. also, the coils wont survive 230 volts.
 
Re:  307200000000 V DC ! sound fun?

Chaining together identical transormers in series is just going to end in tears...

One of them will catch fire/melt/blow up and you're done for.

It might work for 2 transformers for a few seconds- at 120 volts that is.  240 volts = dead transformer.

If you want to daisy chain stuff together to make ridiculously high voltage output, look into spark gaps and high voltage capacitors :)

whats inside a bug zapper(the ones that look like a tennis racket).
