Popping a 5000A Fuse

gentlemen and ladies this video hopefully will be one of the first ever on the internet or youtube where we're going to see a 5 000 temp fuse which is one of the biggest you can actually get get destroyed to destroy this we're going to use astronomic amounts of power the fuse itself is rated at 5000 amps so we're going to need more than 5000 amps to actually destroy this it's extremely big extremely heavy and i think it we need to bust it today so as i say if we put 5000 amps through this nothing will happen because it's designed for 5 000 dams well the way we're going to attempt to do this is using a very large capacitor bank each capacitor is about a thousand microfarads that will deliver twenty thousand amps three thousand volts ten of those in parallel so we'll end up with approximately two hundred thousand amps we're going to use a pneumatic switch that can handle 12 000 amps so that's going to suffer some damage naturally wouldn't be this channel if there was no damage would there but certainly no bones in the carpet on this one because it's outside rightly so this is the current curve you can see 5000 amps five second duration that'll handle 30 000 amps oh deary dear that's a lot of ends but i think we should go straight up here to 200 000 amps because that's what the fuse can actually handle for a peak left for there's our 5 000 amps so we need to be in the 200 ka range to actually pop this thing let's have a go that's probably charged keep on a lead yeah don't dance that's a lot in it that's mad there's a lot for that then there's a thousand capacitors out of the microwave yeah a thousand in there i've got a few strips of this copper bus bar and i need to cut some holes in it so let's get messy i need some careful measuring now the owl scriber good where's miami checking it central [Applause] all right if you know what i'm gonna do my deburring tool it's not the correct tool but it works okay we are making progress good that's that horrible metal work done because i've got swarf all over the house right we've got five capacitors now in parallel these links are simply to link them all in series on a later experiment so they'll all link up so they have 20 kv all in series or we'll have them all in parallel and have 200 000 damns this should be good um clayton's gonna go in there some 185 we've got our links there to link up to the next bank of course there is two of these so it's just one bank there then you've got that lot and they're all linked up together i've got these bars as well all linked up i've cleaned up these terminals just to ensure the best possible connection because we wouldn't want any losses would we we're getting there what you think of that then boys that will go pop these about connections on there shorting bar just for safety those are going to pack quite a punch kaboom baby that's looking good should do the trick there's no movement there nice there's a neat one in it looking good with this one i have opened it up carefully tipped out the sand and you can see all the fuse elements there's about 50 100 amp strips in there all in parallel just to give us the 5 000 amps required this is our control box that we've literally just thrown together there's our arm in switch and to activate it it's via air pressure switch because we don't want any power coming back up a wired lead in our hands so 240 volts go in in the small transformer 72 volts dc that goes out to the pneumatic switch on the solenoid and then of course the compressor actually does to close in so that's the control box all finished not too bad it works here's one of these meters that i was going to use for the capacitor bank unfortunately this one popped in quite a dramatic way this wire link sadly had cut into one of the resistors causing a catastrophic failure so luckily i've ordered another one and i'm gonna modify this so this link is recessed and then perhaps we can put some insulation there but this one's new but it's old so i think that's where the age and the compression of the thing has made that cut into it but it is usable that's a bit better now good that's not going to cut into those resistors like this one problem solved a bit more insulation perhaps well this has definitely improved this resistor network for that meter for a bit more insulation i'm going to pop that in there that can handle 5kv or so i think easy that's definitely looking better two sheets of that high voltage insulation those resistors won't get damaged now will they good shame that but saved by the spare good that's on there like that now we can measure 3000 volts analog just as it should be good bolt that up then what i need to do now is quickly test this meter to make sure it does work if it does that's good news because then we can use it on the big experiment which is downstairs so for now we have a microwave oven transformer diode and capacitor straight on there we'll get it up to 2kv also and see if it works let's zoom in a bit so we can see it good let's test it all right that's a thousand volts let's get it up to 2kv that is looking promising uh the microwave transformer actually offload let's discharge that that should drop like a sack of poo stand by for the bang that's good so what was that the help is what it was smoke coming out of the fuse yours a little wafter smoke coming out of there [Laughter] i wonder if there is any uh bit left in there could go one more a little bit there's still something man it'd be easier to destroy that even more now come on uh it's not dropping any more than that is it oh thank you so ah look at that fuse [Applause] [Applause] that's got it oh there might be a couple of links left i've flown over here spat them out our contact is taking a beating but it's doing it we have a little bit of wire wall in there see what happens with that i don't know if i've got that one naturally i'd like to say thank you for watching the video hope you enjoyed it hope you may have learned something hope it was interesting and very very briefly i did see all the comments and all the likes on that previous video i got the message loud and clear you want videos so i want videos too let's carry on let's uh make this year perhaps a little bit better than what it started so i will see you very soon on the next video thank you very much indeed bye-bye

I wonder what kind of EMP this generated...

Also hope in the process you didn't vaporize/inhale and/or contaminate the surrounding area/s with BeCu.

Glad you don't live in my neighborhood.

I love this guy's channel. Playing with big boy current/voltage is really cool but scares me. I'd probably kill myself or burn my house down

[u/rtuite81]

I'm so glad he came back after a hiatus! It's also nice to see he is able to prioritize life goals, and I'm OK with the ~2-year wait to hear that he's doing well & doing what makes him happy.

Ever notice how most engineers are like mad scientist levels of intelligent to the common man but typically can’t spell for shit? I love it.

[u/aminthemiddletoo]

Fucking Yes!!!!! Big boy supply needs a bit of dusting after this length of time, I wonder how he got the dust off? Something tells me it involved static.

[u/5c044]

Reading a datasheet for a fuse isn't something many hobbyists would do. It's surprising how long they can last at small amounts over rating.

[u/onjayonjay]

That’s a huge hunk of copper. Dang.

[u/onjayonjay]

I dunno wtf is happening but I can respect it and I’m compelled to watch it to the end.
