oil) on its permanent place,even if it is not going to be placed in operation immediately.If this is not possible,the transformer has to be placed in a dry place and the transformer must be filled with oil.If the unit is going to be located outdoors,the water vapor will condense inside the tank,due to the variations in temperature and Chapter 4 Secondary Containment and ImpracticabilityCalculation of secondary containment capacity,based on a design criterion of 110% of tank storage capacity Containment surface area = 45 ft x 20 ft = 900 ft.2.Tank volume,based on 100% of tank capacity = 20,000 gallons Tank volume,in cubic feet = 20,000 gallons / 7.48 gallons/ft.
Feb 24,2012·Function of Conservator Tank of a Transformer.When transformer is loaded and when ambient temperature rises,the volume of oil inside transformer increases.A conservator tank of transformer provides adequate space to this expanded transformer oil.It also acts as a reservoir for transformer insulating oil.Distribution Oil Transformer - 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 conservator.The types of magnetic circuit are: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
