    1. Fire Sprinkler International 2014 Name: Andreas Teckenburg London, 20. May 2014 • FireProtection Solutions for Transformers„TrafoProtect“ by Minimax 8 von 36

    2. Agenda • Initial Situation • Goal setting • Trials • FireExtinguishingConceptTrafoProtect 9 von 36

    3. „The risk“ • 1) Initial Situation • Protectivegoals: • Avoiddamagetopersons • Reducedamagetoenvironment • Reducebusinessinterruptions • Protect material asset • Avoidlossofimage • Obtainjobs • Malfunctionmechanismsoftransformers: • Mechanicalloadbyforcesofelectricalshortage in windings • Electricalloadby transient excessvoltage • Mechanicaldefectsoftheloadlevelswitch • Defectof a conduct • Thermicalorelectricalagingoftheisolators 10 von 36

    4. Different Guidelines/ Rules • 1) Initial Situation • European Approach: • VdS 2109 VdS-Richtlinien für Sprühwasser-Löschanlagen, Planung und Einbau • TS 14816 European technical Specification, Fixed fire fighting systems - Water spray systems - Design, installation and maintenance • US Approach: • NFPA 15 Water Spray fixed systems for fire Protection • NFPA 11 Low-, medium- and high Expansion foam system • FM 4-1N Fixed water spray systems for fire protection • FM 5-04 Transformers 10 von 36

    5. Different design parameters • 1) Initial Situation national / international • VdS 2109 (12.4): • Waterapplication: 15 - 30 mm/min • Operating time: 5 min (Step-in-time ofthefiredepartment) • NFPA 15 (7.4.4): • Waterapplicationtransformerandaccessories: 10,2 mm/min • „Endangeredterrainsurface“: 6,1 mm/min • Operating time: „As longastheexpositionstops.“ • NFPA 11 Schaumlöschanlagen: • Protectionoftansformerswith medium foam. Nodesigning. • FM DS 5-04: • In rooms (2.2.1.2.2) withsprinklerat15 mm/min or FM-approved„Machineprotectivesystem“. 12 von 36

    6. Agenda • Initial Situation • Goal Setting • Trials • FireExtinguishingConceptTrafoProtect 9 von 36

    7. 2) Goal Setting „Creationof a protectionconcept valid andcertifiedinternationallywhichenablesthe „economicallypriced“ fireprotectionoffree-standing transfordermswithpreferablysmall design parameter.“ • Protectionoftransformers; also for„decentral“ substations (municipial utilities, etc.)  Influenceof wind ? • Ifnosufficientwatersupply (amount, pressure) isexisting (existence, newbuilding) • Protectionoftransformerswithlessextinguishingwater. Mostlythetransformeristhe „waterdetermining“ component in thewholeproject. • Reducingof „contaminated“ extinguishingwater. • „The Scope“ 11 von 36

    8. InspectionandCertificationofthe Installation Engineering • 2) Goal setting Courseoftheprocedure: • Collocationofinformationandrequirementsofthetestingcenters, but also theoperatorsandinsurer (e.g. HDI Gerling) • Preparationof a testconceptbyDMT • Set-up DMT / UL • ExecutionofthetestsatDMT • Creationoftheplanningandinstallationinstructions 12 von 36

    9. Agenda • Initial Situation • Goal Setting • Trials • FireExtinguishingConceptTrafoProtect 9 von 36

    10. T1 und T3 F3 T4 T2 T1 und 3 T2 F2 F1 T1 und T3 T4 • Experimental assembly in thefiretunnelat DMT, Dortmund • 3) Trials • Lateral view • Topview Size ofthe „Mock-up“: 2,8 x 2,2 x 2,5 m (W x D x H) Wind direction

    11. 3) Trials • Experimental assembly in thefiretunnelat DMT, Dortmund

    12. Firetestsandresults (genericexample) • 3) Trials • Trial goal: Firesuppression • Puddle, Stream and spray fireunder different conditions • Nozzlesinstalled on onesideonly in thetrial; safetyfactor • Nozzlepressureandwaterquantitywerelower in thetrialsthan in thespecific design rule

    13. 3) Trials • Impressionsofthefiretests

    14. Agenda • Initial Situation • Goal Setting • Trials • FireExtinguishingConceptTrafoProtect 9 von 36

    15. The Minimax ProtectionConcept • 4) FireExtinguishingConceptTrafoProtect • Transformer isregardedas „lost“ in caseoffire • Firesuppression/ Firecontrol; noextinguishingnecessary • No „special“ components; e.g. high-pressurewaterfog = stainlesssteel, filter, „specialfittings“ • Certificateswithoutsizerestriction, testingunder „influenceof wind“ !!International: UL VerificationDeutschland: DMT Eignungsbestätigung • Waterapplicationwithsafetyfactorislowerthanaccordingtotheguideline

    16. 4) FireExtinguishingConceptTrafoProtect • ApprovalandCertification • Components are allUL listed • Trial resultsacceptedbyUL and DMT • Specificplanningandinstallationinstructionschecked an acceptedby UL und DMT
