X.Transformer oil 7.Design detail Output of transformer let 8. the capacity of the transformer increases,the losses and the To overcome the problem of atmospheric hazards,the transformer is placed in a steel tank filled with oil.The oil conducts the heat from core and coil to the tank walls.From the tank walls the heat goes DEVELOPMENT OF POLE-MOUNTED DISTRIBUTIONtransformer volume would be very limited because of relatively small share of those components in total volume of transformer (only 12% as per Table 3).They could play more important role in weight reduction.Weight of tank is directly linked with volume of oil.So,reduction of oil volume is the key for reduction of weight and dimensions.DISTRIBUTION TRANSFORMERS - alfanarThe transformer tank is usually a non-rigid structure with corrugated panels,designed to withstand the mechanical stresses,absorb the oil expansion,and meet the thermal evacuation constraints.For power rating above 3150kVA,the tank is usually designed with rigid structure,cooling radiators and
The transformer tank is usually a non-rigid structure with corrugated panels,designed to withstand the mechanical stresses,absorb the oil expansion,and meet the thermal evacuation constraints.For power rating above 3150kVA,the tank is usually designed with rigid structure,cooling radiators and conservator.The types of magnetic circuit are:DISTRIBUTION TRANSFORMERS SPECIFICATION #12125.7.1 Transformer tanks shall be of welded steel construction.The tank shall be a conventional,oil-filled,pole-type with only one pole-mounting position.5.7.2 The tank covers shall have a slope of 10-15 percent for moisture runoff and shall have an insulated -Distribution and Power Transformersnon-rigid tank completely filled.Air cushion in used with rigid tanks.The variation of oil volume,due to its temperature variation,is absorbed in the flexible fins of the corrugated panels,and in the air cushion when applicable.Breathing tank with conservator is also a possible configuration.2.3.2.Tank types
In practice the temperature difference may be more than 100ºC,so the volume of the expansion tank should be 9-10% of oil volume.There is also such parameter is specific gravity of transformer oil.It must be relatively low,since it allows the sediment to separate more easily and to settle better in the transformer,not hindering the circulation of the insulation fluid.Ground-mounted distribution transformersFlexible corrugated tank walls or radiators enable sufficient cooling of the transformer and compensate for changes in the oil volume due to temperature variations during operation.Larger ground-mounted transformer can also be supplied with on-load tap changer (OLTC).Guide for Transformer Fire Safety Practicesassess the probability of a transformer fire event occurring in its transformer population.Chapter 4 Discusses the physics of arcing within transformer tank and gives formulas and examples on how a user might be able to predict the likely range of arcing energy,volume of gas
