S950010 10kVS950HzS9-500/10The Design and Calculation Of S9-500/10 Distribution TransformerAbstract10kV series of S9 three-phase oil-immersed cold-power transformers, for the exchange of 50 Hz as the power supply system in the distribution of power, transform voltage use, but also for indoor and outdoor continuous use. Transformer calculation and design, is based on the rated capacity of the transformer, rated voltage, linked groups, short-circuit impedance, load loss, no-load loss and no-load current major products such as technical parameters, in accordance with national standards and related technical standards, the S9 - 500/10 distribution transformers for the calculation of a mock design. Mainly through the circuit transformers, magnetic circuit and leakage magnetic effect analysis, the basic form of winding, parameters and size, choice of core structure, the calculation of core size and weight, no-load loss, no-load current, temperature rise and short-circuit impedance calculations and insulation types of choices.Key words: Transformers, Core, Winding, The height of windows, The center distance 500KVA 105%0.4KV 50HZ Yyno 4% 5150W 960W 1% GB1094 GB6451S950010455% S95001011 S950010kVAkV%kgmmS9-500/10500100.44Yyn0100050001.43601155188015701250161012abcdefgM0hijkl11 11232a b c 3 S9500101-11-1 S9500101-210KV35KV630KVA80mm400mm1-2 1-31-3 ()BBBB1.7T1.75TDQ147-301.69TDQ14730 DQ14730 7.65g/(HZ)506000.0500.050.50.1110.1320.1470.1750.60.1540.1800.2030.2360.70.2070.2330.2710.3080.80.2660.2980.3480.3930.90.3330.3690.4420.4891.00.4080.4520.5420.5981.10.4910.5400.6500.7141.20.5840.6400.7710.8371.30.6900.7520.9060.9821.40.8090.8781.0621.1511.50.9601.0431.2501.3811.61.1561.2921.4901.6501.71.4281.6171.8472.0801.81.8252.0342.3392.6021.92.2432.878 1mm ,1-1535754 kVAkVAmt =500KVA/3=166.7KVAmm1-1 KK110kV53575155220kV53575155220kV51552(1-4)0.962cm0.971.151-4 3a700.00150.003mmb2500V23Mc1-5 1-5 4kg8 abcd35KV302-12-1 MA105QE120QQQAQANB130QZQZNF155QZYH180C180QY2-12-1 2-22-2 KVAKV6300.45003106303520006080010000.4125020000.4400010000316000500006400006300010315003531500608003150380010000663010800352500605000110315002201235KV400KV32mm2-2 2-2 434mm10mm42-32-3 510mm15mm V50HZ1.69TV 100005%V 1050V 10000V 950VV V V 400V V A A A V a577 523 577550=550523=27b 1958551095815557722111ZB2-3ZB-0.45 1.75.60.45mm 1.70.455.60.452.156.052-3 9.1572ZBZB-0.45 5.
