Q:How much W?
Ee22 how much of the transformer can be related to the material used. If the material is good, high frequency loss is relatively small. Transformer (Transformer) is the use of electromagnetic induction principle to change the AC voltage of the device, the main components are primary coil, secondary coil and core (core). The main functions are: voltage conversion, current conversion, impedance conversion, isolation, voltage regulator (magnetic saturation transformer) and so on. According to the purpose can be divided into: power transformers and special transformers (electric furnace change, rectifier, frequency test transformer, voltage regulator, mine transformer, audio transformers, IF transformers, high-frequency transformers, impact transformers, instrument transformers, electronic transformers , Reactors, transformers, etc.). Circuit symbols commonly used as the beginning of the number. Example: T01, T201 and so on.
Q:What is the meaning of the transformer capacity unit KVA?
KVA for apparent power, its size and power factor! For example: power factor cosΦ = 0.8 active power P = 1Kw Then tgΦ = 0.75, so the square of the apparent power S = the square of P + the square of P * tgΦ When the power factor is 1, 1KVA = 1KW
Q:How to use a multimeter to determine the quality of small transformers
First with a multimeter resistance file RX1 or RX10 to test the transformer on both sides of the coil! Have to pass! Primary resistance large! Secondary resistance small! (Buck) And then test the first class! Can not pass! Basic determination is good! And then use the transformer at both ends of the primary coil to take the multimeter AC voltage 50-100 volts stalls! With a dry battery to touch the transformer secondary coil ends! At this point multimeter watch pin should have a strong swing! Induced current and mutual inductance voltage! This proves that the transformer all normal! No turn-to-turn short circuit!
Q:What is the meaning of the high voltage side and the low side of the transformer?
High voltage side called high side of the low voltage side called low side
Q:What is the impedance voltage standard of a power transformer?
10kV / 0.4kV non-excitation or on-load regulation: ≤ 500kVA, 4%; ≥ 630kVA, 4.5%; 10kV / 3,3.15,6.3kV without excitation: 630kVA, 4.5%; ≥630kVA, 5.5%; 35kV without excitation: ≤2500kVA, 6.5%; ≥3150kVA≤5000kVA, 7.0%; ≥6300kVA≤10000kVA, 7.5%; ≥12500kVA, 8%;
Q:Transformer ONAN?
ONAN refers to the natural cooling of oil. Common have the following cooling methods: Oil immersion (ONAN); Oil - air - cooled (ONAF); Forced oil circulation air conditioning (OFAF); Forced oil circulating water cooling (OFWF); Forced to guide oil circulation air cooling (ODAF); Forced to guide the oil circulating water - cooled ODWF).
Q:The difference between transformer power kva and kw
Kva is apparent power, KW is active power. inspecting power: S = 1.732UI = 1.732 × 0.38 × 100 ≈ 65.8 (Kva) Active power: P = 1.732UI cosφ = 1.732 × 0.38 × 100 × cosφ
Q:Proteus transformer how to adjust the parameters, the 220V into 14V output.
Transformer parameter setting method is: 1, the calculation: According to the ideal transformer primary turns ratio ratio n1 / n2 = V1 / V2 = 220/14 ≈ 15.7,              Let the primary winding sense L1 = 1H, then the secondary winding inductance L2 = 1 / (15.7 ^ 2) ≈ 0.00406H,
Q:What does S11-M-500/10 transformer mean?
The first floor has been very accurate to answer my answer that M is sealed!
Q:Transformer voltage range of 10.5 ± 2 * 2.5% kV and 10.5 ± 5% kV What is the difference
Two transformers of the same voltage range, but the tap is not the same, the previous one is 5-speed regulator, select the relatively small, more adaptable. The latter is the third gear regulator, sometimes with the actual time required to have the voltage difference, mainly to see that your load is stable and unstable. These two kinds of voltage regulator for the basic price of the transformer has no effect.
