The workings and functions of each part of the transformer

A transformer consists of several parts that have functionseacha. The main part

1 ) iron coreIron core serves to facilitate the flux path , whichcaused by an electric current through the coil . made ofthin iron plates are insulated , toreduce heat ( as the iron loss ) caused bynavel currents or eddy currents .2 ) coil transformerSome insulated wire coil to form a coil , andThe coil is isolated , either the iron core andthe other coil using solid insulationsuch as cardboard , Pertinax and others.There transformer primary coil and coilsecondary . If the primary coil is connected to thevoltage / alternating current in the coil then arisesflux that causes a voltage induction , when the circuitclosed secondary ( load circuit ) the current flowing inthe coil , so the coil is functioning as a toolvoltage and current transformation .

3 ) tertiary coilCoil tertiary function is required to obtaintertiary voltage or for other needs . for the secondthis purpose, the coil is always connected tertiary deltaor triangles . Tertiary coil is often used also forconnection of auxiliary equipment such as condenser Synchrone ,shunt capacitors and shunt reactors , however, not allpower transformer has a tertiary coil .

4 ) Transformer OilMost of the power transformer has kumparankumparanwhich essentially immersed in transformer oil ,especially on the transformer - transformer powerlarge capacity , because the transformer oil has propertiesas the heat transfer medium ( recycled ) and also servesas well as isolation ( has a high breakdown voltage )thus serves as a coolant and insulating andtransformer oil must meet the requirements , namely :􀂃 high insulation strength􀂃 channeling good heat , density is small , soparticles in the oil can settle quickly􀂃 low viscosity , in order to more easily circulate andhave the ability to get better cooling􀂃 high flash point and can not easily evaporatepose a danger􀂃 not damage the solid insulation material􀂃 stable chemical properties
