Fire Protection in Substation Transformers TD World

Fire Protection in Substation Transformers.Oil-filled transformers pose the greatest fire risk in any substation.As modern society takes uninterrupted electricity supply for granted,electrical utility providers are increasingly measured by the reliability of the infrastructure used to deliver power to consumers.Fire Protection in Substation Transformers Utility ProductsWhere a firewall is provided between transformers,it should extend at least 1 ft (0.31 m) above the top of the transformer casing and oil conservator tank and at least 2 ft (0.61 m) beyond the width of the transformer and cooling radiators or to the edge of the containment area,whichever is greater.Power transformer fire protection systems 1.Fire protection for power plants (NFPA 850) - EnggCyclopediaWherever a firewall is installed between transformers (please refer to the picture below),it should extend at least 1 ft (0.31 m) above the top of the transformer shell and oil tank and at least 2 ft (0.61 m) beyond the width of the transformer and cooling radiators.Fire protection for indoor transformers.Dry-type transformers are strongly preferred for use inside buildings.In case however,an oil-insulated

Hydropneumatic Tank Control Systems

Hydropneumatic tanks work best with an air cushion of ¼ to ½ the tank capacity.This cushion decreases as water absorbs air and the tank loses its ability to pressurize the system.To keep that from happening,there must be an automatic way to replenish the air volume.Adding air manually isInterview with Arnaud Magnier,Vice President at SERGI Apr 06,2017·A long journey to the ultimate safety.SERGI was created in the 1950s by Electricité de France (EDF),the French owned electricity generation,transmission and distribution company,which needed a solution for extinguishing fires caused by transformer explosions.At that time,SERGI used to design and manufacture a system called Drain and Liquid Filled Transformer ApplicationsThe installation complies with all restrictions provided for in the listing of the liquid.(2) With an automatic fire extinguishing system and a liquid confinement area,provided the transformer is rated 35,000 volts or less (3) In accordance with 450.26 (Oil-Insulated Transformers Installed Indoors)

Liquid storage Guidelines

Take into consideration the capacity displaced by other tanks within the same bunded area and any foundations.Treat interconnected tanks as a single tank of equivalent total volume for the purposes of the bund design criteria.For flammable liquids,bund capacity should be at least 133% of the net capacity of the largest tank.If an automatic fireNS189 Oil Containment for Major Substationssubstations fire-fighting water containment capacity shall be made for up to 90 minutes of expelled fire-fighting water For both non-rural and rural sites,the minimum containment storage for non-fixed firefighting is 20 minutes of one hose with foam at 4 l/s The required minimum storage can be inclusive of volume available in bundedNitrogen A Security Blanket for the Chemical Industryvapor space of a storage tank or process vessel,making it inert.This eliminates the possibility of fire or explosion,decreases evaporation,and protects the tank from struc-tural corrosion damage caused by air and moisture.It also prevents air,moisture,or other contaminants from enter-ing the vapor space and causing product degradation.
