I meant salvage and junk in some parts where I said "scrap". Things I haven't done: 1: Modify transformer, cut off filament transformer connections, parallel up the xrt primary with the other for more current capability (This requires draining out some oil to work on it easier, etc.) 2: I might want to modify the tank/lid a little, and that is replacing the lid with persplex/plexiglass, install some either 3d printed insulators, or bought insulators 3: Change the driver from TL494 to SG3525 so I can adjust duty cycle at much lower frequency without issues, for current limiting without having to use ballasts/MOTs in series
This is my first large transformer, that's oil filled, powerful, and also an xray transformer. I've had one xray transformer before, but it was 500W rated, 65kV 7.5mA. It didn't last long because I didn't really have much knowledge or experience with them and I never had a pretty HV transformer before. If it wasn't for Tested to Destruction, I probably would have already killed this transformer open circuit.
X-rays are actually quite fun once you understand them and know how to mess with them safely. I begun with HV, now Im more facinated by the X-rays than HV, im building my own from scratch now, it Is just the beginning so rn Im learning how to build high frequency transformers and bridges.
I was sad to see in the last video that you want to sell everything. Then I was happy because I can buy good things from you Thank you for your guidance on setting up the X-ray trans in the comment below, which is exactly the same as your trans
Very cool! The sound frequency reminds me a bit of a violin. You might be able to use a raspberry pi to generate Beethoven, or some classical music, which would be awesome/interesting. Just a thought. Keep up the tinkerings! Be safe!
hi dear friend. I thank you for your video. I watched all the episodes of your X-ray trans video series, but my English is poor. Well, I didn't understand what circuit I should use for the best start of this transformer I bought an x-ray trans exactly like yours and want to run it with a variac OR Or the best way to get the maximum voltage and power. I shorted the MA+ AND MA- pins and connected the output of the variac to P1 AND P2, But at low voltage, more than 25 amps flowed from the variac I could not download the PDF circuit you attached Thank you for guiding me for the best setup of this trans. THANKS DEAR TRENT HV
I don't know a ton about x-ray stuff, but I feel like 40kw is a ridiculous amount of power. I suppose it's only a 40kw pulse for a very brief amount of time, but this transformer is obviously WAY over engineered for that. I'd imagine this x-ray machine could potentially way over expose someone
Lol... for xrays you need a tube with highvoltage AND filament to do that. Xray transformer is just a high voltage transformer. I can only do like 15-20kW for maybe a few seconds max each run
Not disgust I don't think, but more like just pretty skeptical or doesnt like my hobby because of how dangerous it is. And I completely understand lol. He needs to know that I've been doing this for 8-9 years and I've learned a lot, especially safety
Just verified with 3:07 of your video that mine is also a 46-270954G1. Mine was September 1994. I'd be curious to know if you did any modifications to the inside, or if you just ran it as-is? I've yet to design/built the driver for it. I got 2 IGBTs and was thinking of doing fullbridge..did you opt for full or half? I had the impression from the manual ( full schematics of the entire unit ) that this was a 100VDC 1KHZ drive system. In your other video I saw you running it at like 300VDC..are these rated for more? Id be curious to know your driver setup as I feel I maybe over complicating it haha
Already answered on dc but for anyone else: this was designed to be run resonant, with a resonant capacitor in series, so probably around 150-200V+ rms. May or may not be stepped up with a step up transformer (it looks like), not entirely sure. I just give it full voltage of my variac (290V unloaded), around 350-400V max at lower current, 260-300V at higher current. DC. Its probably like 250V rms input of xrt, at higher current, 300+ at lower current. I haven't measured. Anyway, I just use a full bridge because I prefer it. Half bridge gives you half the voltage and twice the current (or same current? Idk) which would heat up the wires a lot more, especially the primary (it will overheat the terminals and the equivalent 10awg primary coil), I just use a full bridge to get like full output voltage basically and also lower current so it doeant heat up as much. And the wires
thanks, and yeah, you will eventually. just keep looking around on ebay, scrap yards, etc. heck, even ask around in hospitals, chiropractors etc if theyre throwing out xray machines
@@trenthighvoltage bruhh 3 machines... Thats crazy. But is it just a big ass ferrite transformer inside the oil? What is the difference between a usual hv transformer and an xray one?
@@TrenboloneAcetat Uh, capacitors. Lol, 4x 3900uF 500V, total 15,600uF. And no, my IGBT driver uses a simple SG3525 driver with higher current gate drive ICs to control the gates, frequency and duty cycle adjustable. Allows you to use a LOT of power, a very large range of frequency, and from 0% to 45 to 50% duty cycle. ZVS drivers can't really do that. ZVS uses a resonant LC circuit/tank, IGBT drivers does not.

Look online for the "General Electric SCR Manual" for those inverter circuits.
Those portable X ray machines have a very nice inverter and other cool parts. The tube has a rotating anode in it.
SCR's are worthless for me. This is from 1991. And I'm aware that the tube has a rotating anode, this is a part 1

I need to get one of those

I’ve seen guy how spared induction heater and hv transformer. Primary coil hook up to a heater directly. 60kw. That arc was massive.
Some of these x-ray transformer's might be capable of charging EVs directly from power lines.
A great acquisition Trent, and a brilliant demonstration too. I can tell that you're very, very pleased.😊
Thanks

you will eventually, you're just gonna have to look around, or save up for one on eBay

why dont u use a driver circuit like in a sstc? it has all the protections and you can put midi song in
what protections lol it's just a full bridge igbt driver
treat this XRT better than twee does :P
