Batteries for 6.6kV Switchgear Panel

Sunilji,

You can go and have a look at barterries used in your substation, i don't think they use SMF for a reason i may think is that if any of the sets of the battery fails you will not know and charger will continue charging these batteries, if you have a system disturbance your system will fail since it was being powered by the charger.

About the gasses you may need to put an extration fun if its in an enclosed room.

Dear Sunilji

While I agree to what Waco has already pointed out, but then you will have to decide, since location of the battery & charger is such that there will be human movement. SMF is not the best choice for substation application, one of the reasons has already been written by Waco. Other problem is due to temp. If the ambient is in excess of 35 deg. C then the electrolyte recombination in SMF battery reduces and after some time, it goes below the required level. Battery capacity also goes down and eventually fails, without giving any warning or indication.

Tubular lead acid battery requires separate room with ventilation and acid proof/resistant tiles for floor & requires maintenance but lasts much longer. I have even come across an instance wherein a company "forcibly" replaced the tubular lead acid battery after 19 years of installation, though it was still functioning. This is a rare case and most of the batteries will not last more than 8-10 years depending on maintenance etc. We supplied the charger for their new requirement.

We are an ISO 9001-2000 certified manufacturer of chargers with DB and supply complete system with battery ( SMF/tubular/NiCd, depending on customers requirement ) for power plants and substations. Apart from India we have installation in 12 other countries. Kindly send enquiry to uni_insta@dataone.in with cc to ashoktoshniwal@yahoo.com.

Thanks and regards

www.enersys.com look at powersafe SBS-190 or anything in the Odyssey line up

need to have a three stage charger that has a minimum 13.6V in float

"www.enersys.com look at powersafe SBS-190 or anything in the Odyssey line up

Isn't 13.6V alittle low for the float setting on a 110V bank?
