    medium frequency induction furnace transformer technical requirements

    1. Model: ZS-2450/10 (12-pulse 6-phase bridge full-wave rectifier transformer with phase shift-7.5 ¡ã )

    2. Rated capacity: 2450KVA , each group of harmonic currents on the low-voltage side is as follows:

    (5 times 17.5% , 7 times 11% , 11 times 4.5% , 13 times 2.9% , 17 times 1.5% , 19 times 1.0% , 23 times 0.9% , 25 times 0.8%)

    1. Voltage ratio: 10KV / 0.575KV no-load voltage regulation 10KV +/- 2.5%

    2. Rated short-circuit impedance: 5.5 - 7.5% , Y , ¦¤ winding rated impedance is equal The neutral point of the Y -connection is not taken out and is not grounded.

    1. Link group label: Dy11 , DD12 ( ¦¤ / Y , ¦¤ )

    Primary phase shift -7. 5 ¡ã (-7.5 ¡ã phase shift and provide a vector) phase shift error of the phase angle should not exceed 0.35 ¡ã

    1. Y , ¦¤ winding voltage difference is as small as possible, the maximum can not exceed 0.28%

    2. Number of phases: 3- phase input 6- phase output

    3. Rated frequency: 50Hz

    4. Cooling method: ONAN cooling medium: 25# transformer oil

    5. Maximum indoor working temperature: 45 ¡ãC

    6. Oil surface temperature rise: less than 50 K winding temperature rise: less than 60K

    7. Insulation level:Primary power frequency withstand voltage: 45KV primary side full-wave impulse withstand voltage: 95KV£¬Secondary power frequency withstand voltage, secondary full wave shock withstand voltage: refer to national standard The secondary must bear 3300V to the ground at any time

    1. Electrostatic shield protection between primary and secondary windings

    2. The inlet and outlet wires are fixed to the top cover of the transformer with a sleeve

    16. The relative position of the oil pillow and the high and low pressure outlets . ( Low pressure side close to the VIP cabinet )

    1. Accessories: Should be equipped with oil filling valve, gas relay, oil level indication, thermometer ( disc type, can be set manually ) , discharge valve, pressure relief valve, marked signage, grounding end, lifting ring around, use no Load-regulating switch with locking device.

    2. The heat sink should be placed symmetrically, and the butterfly valve should be installed at the joint between the heat sink and the transformer body.

    3. Load loss:

    4. Dimensions: length X width X height

    5. Installation gauge: gauge distance 1070X1070 square, channel ring

    6. There is a junction box next to the transformer, which has terminals, one side connected to the thermometer, gas relay and other signals, and the other side connected to the high voltage switch cabinet.

    7. Reference Standards: ANSI, IEC, GB 6451 , GB1094 and JB/T8636-1997 Current Standards for Power Converters.

    8. Technical Information:

    a)Transformer assembly drawing

    b)After the design of the transformer outline drawing ( AUTOCAD ) is completed, EMAIL will be sent to our company, and then confirmed and put into production.

    c)Transformers, bushings, general components, oil conservators, gas relays, temperature controllers, radiators, unloaded tap-changers, pressure relief valves, etc.

    d) Gas relay factory test report

    e) Product test report

    f) Product certification

    g) The above technical materials are shipped randomly, and a copy of the above technical information is sent to Yingda Industrial ( Shanghai ) Co., Ltd. for archival purposes.

     Service: If the transformer oil storage cabinet and radiator are shipped in bulk, the manufacturer dispatches relevant technicians to the user's work site to perform on-site installation and commissioning of the transformer (the manufacturer is responsible for installing the oil conservator, gas relay, temperature controller, radiator). And on-site refueling, etc.).
