transwave static lost its magic smoke

Postby wallace » 03 Jun 2015, 11:38

Hi all whilst using a machine I heard a slight electrical popping sound coming from somewhere. I investigated and found some magic smoke and a few small flames coming from my static converter. :shock: I isolated the supply and kept an extinguisher ready just incase some thing caught.
I left it for a while before opening things up capacitors hold a charge for a while don't they?

You can see a capacitor has popped

Heres a close up of the writing

Can anyone advise me where to get a replacement, I checked ebay but would like some one more nounce than me to advise.
Is there a way to check the other capacitors?
thanks Mark

from the picture you need a 10 uF capacitor (uF is micro farad so you will see it listed as 10 MFD on ebay) and it needs to be at least 440V rated.

Obviously spade terminals and I'm guessing stud fixing will make replacement easier.

edit.

first one i found on ebay looks to have the right terminals etc - http://www.ebay.co.uk/itm/Run-Capacitor ... 3ce860dd46

Thanks chaps, I remembered my motor winder friend and took the old one with me. £3 for a new one. :D Very happy result. He just charged me cost. Would it be worthwhile replacing the rest of the caps?

I'd not bother until they go bang. It is usually a very rapid decay from working to bang unless there are any signs of bulging or stains round the cap/seal

They are all made of "self extinguishing " materials these days and not a serious fire risk especially in a metal box.

Thanks Bob, I could probably do with a decent rotary because this static gets some hammer especially when trying to start the 30" bandsaw. I have a motor setup with no load to improve the starting on some machines.
Mark your not wrong I now have 5 machines outside my workshop begging to come inside and be made pretty. I made a promise to me lady that no more restorations until some serious wood is butchered
