Building Transformer in explosion proof enclosure

[WilliamAng]

Hi,

i would like to place a 60kVA 3-Phase Dry Type isolation Transformer into a explosion proof enclosure.

but i'm worry about the ventilation inside the explosion proof enclosure for the transformer.

Please help.

William

The fibreglass ones have a blast roof built into them which lifts off in the event of an explosion, and they have vents built into the sides.

Can the project include air conditioning? enabling you to keep the unit sealed.

thanks for your reply.
other then fiberglass?
because the project required the explosion proof enclosure to be in Steel or Metal material instead of fiberglass.

kindly advise.

Thanks for your reply bro.
nope. they just wanted the transformer to be alone in the Explosion proof enclosure.

Tricky one as the tranny will be air cooled and at the same time you cannot use normal ventilation as it is bomb (nuclear?) proof?
Let me know what you decide on, very interesting project. Lucky you

When you say you need an 'explosion proof' enclosure what Zone is the transformer in? What level of protection is required?

A cast resin transformer would probably suit the job. But move information is needs if it’s an hazardous environment.

I should hope it's not nuclear, someone working on that should not need to ask questions

If you read E&T we’re short of engineers to work on any new nuclear power plants. They’ll be having to use this site.

Can't see how you can use an ''explosion-proof'' enclosure for a transformer that needs a flow of air across them to keep them within their temperature limits. Mind it is a very tiny unit your talking about!! lol!! I suppose it will depend, if it will be supplying a load at or near it's rating value...

"URGENT!!!!: do the control rods go in or out to slow the reaction? I can never remember, LOL! Plz answer quickly, its getting quite warm in here!!1!"

You need to go to a specialist company, the only one I can think of that does Steel explosive relief kiosk is PSF Wales and sister company to Morgan Marine GRP. Here's there website PSF Wales, Steel Enclosures and LPCB Certified Housings, Steel Industrial buildings

Just as a matter of interest are you protecting the transformer from the environment or the environment from the transformer if that makes sense.... basically are you wanting the transformer to withstand an explosion and carry on running or is it a potentially explosive environment.... or you just stopping potential injury if the transformer internally breaks down?

Was thinking that myself...............are you talking about Zone 1 or 2 hazardous area here and wanting a 60Kva tranny inside an Exd enclosure?

Easier to put it in the MCC or safe area surely?
