10,000J Cap Bank

On this page one can find the massive cap bank i build while doing the Papp noble gas engine build. I happen to grab theses caps off of eBay for cheep. I was told they cam out of a 10,000Amp VFD Drive. I was looking to buy 10 of them for the Papp experiment, but for the price i just could not resist! So i bought 50 of them... and build the 10,000J bank:

and the 10,000Sub subscribers special :

 

Here are some photos of the build:

Theses are 3,300uF 350V DC Semens B43570-A4338-Q caps. 20150105_105859_HDR

Here is the safety circuit a came up with. i can add to this as well for charge cutoff or power loss safety. This is remote controlled for a no touch discharge.  thanks to battery Phill for the remote!

I'm using a massive 5kVA power-state along with a 3Kva Step Down Transformer connected in reverse to output up to 500VAC.
