Electric Arc Furnace Serial Furnace Reactor 30mva Three Phase Oil Immersed Iron Core Serial Reactor

Specialized in the design and construction of industrial transformers*• Through-put rating up to 150 MVArIn electric arc furnaces, which use long arcs and high values of secondary voltage, it is often helpful to introduce an additional reactorwith the purpose of:Arc stability and power regulationOptimisation electrodes consumptionLimitation of current during smelting processReduction of flicker on the feeding network.The reactors are series connected with the furnace transformers and have some regulation taps (for the reactance regulation) operatedwith either an onload tap changer (OLTC), for maximum flexibility, or with a de-energized tap changer (DETC). The reactor can be assembled:Inside the main transformer tankEntirely separated from the transformerLocated next to the transformer (On Board Reactor).In the OBR (On Board Reactor) solution, the reactor and the transformer are  linked by a removable cable duct.Extends equipment lifecycle due to reduced unstable arc furnace currentsHigh mechanical strength withstands elevated forces caused by elevated switching currentsTap adjustment is possibleInductance of the reactor is frequently variable and requires large adjustment stepsConservative temperature rise ensures extended service lifeSurface treatment protects against UV radiation and pollutionEnvironmentally friendlyMaintenance-free designAuxillary voltage for power circuits220 Vac, 50 Hz , 3 phaseControl Voltage24 VdcNominal Voltage34.5 KV 50 Hz, 3 phaseRated capacity51.840 MVArRated current2400 AX ( Ω/phase )3ΩInsulation level ( 1U,1V,1W )95/250 KV BILVector GroupiiiMaximum allowable temperature rise for oil60 KMaximum allowable temperature rise for winding65 KNumber of positions 7 ( pos1: 0 Ω, po2: 0.5 Ω, pos3: 1Ω , pos4: 1.5 Ω, pos5: 2 Ω, pos6: 2.5 Ω, pos7: 3 Ω,Tap changer mechanismOn-load tap changer, MR brandOil filter equipment for OLTCAll diverter switch compartments oil will be circulated through a filter circuit equipped with filter clogged electrical signal.Shell and tube heat exchangersdouble wall type, quantity two , each with %100 cooling capacity. Inlet water temperature: 35 C. 2 oil circulation pumps. Temperature and flow indicators both for oil and water circuitsReactor condition monitoringOil level indicators for expansion tanks, oil and winding temparature indicators.Reactor protectionBucholz relay with relevant alarm and trip contact connections. Pressure relief valve for tank over pressure protection, equipped with trip contact./* January 22, 2024 19:08:37 */!function(){function s(e,r){var a,o={};try{e&&e.split(",").forEach(function(e,t){e&&(a=e.match(/(.*?):(.*)$/))&&1
