Substation/Switchroom Fire Suppression

Substation/Switchroom Fire Suppression

Substation/Switchroom Fire Suppression

(OP)
G'Day All,

What are the latest trends with the type of fire suppression systems being used in substations and switchrooms containing H.V, M.V. and L.V. switchgear and MCCs?

What is being used instead of Halon?  Is there an alternative to CO2?

Thanks.

RE: Substation/Switchroom Fire Suppression

As you probably know, Halon is no longer available because it is an ozone depleter.  There is a replacement for Halon, but I can't remember the name right now.  I'm sure if you contact one of the major fire system companies, they can give you the information.  

A lot of this comes down to local fire marshall requirements and your insurance underwriter.  I have seen installations where fire marshall required the installation of sprinkler systems in electrical rooms, despite all of the arguments against this approach.  

I don't think you can apply C02 to any space that could be occupied.

RE: Substation/Switchroom Fire Suppression

I went through the scenario described by DPC, and was forced to install a water sprinkler system in a 35kV transformer vault with MV & LV open bare bus.  (By the insurance co.)  

They did allow us to lock out the water valve, with the fire cheif having the only key, and add signs and give instructions for the safe use of the valve.

RE: Substation/Switchroom Fire Suppression

I am working in a Petrochemical Plant where we are currently using Halon 1301 but we are now replacing halon with Foam system called as FM200 system which is replacement for Halon system. You can contact any major company dealing in Fire fighting system and you can get the quote for the same. It is advised not to use water sprinklers for electrical fire.

RE: Substation/Switchroom Fire Suppression

I agree w/ makpal....FM200 seems to be the standard now-a-days.  However, there is another product called Inergen(sp?), which is supposedly used as well.
