Q:Which is good for the transformer?
and other electrical equipment. Product design novel, small size, handsome in appearance, with low loss, low noise, impact resistance and so on. Widely used in industrial and mining enterprises, textile machinery, printing and packaging, petrochemical, schools, shopping malls, elevators, post and telecommunications, medical machinery and other needs of the normal voltage guarantee occasions.
Q:What is the transformer capacity ratio? Capacity than 100%.
Have not heard, you say is not the main transformer parallel run between the main transformer and the capacity and capacity of the ratio, or the meaning of such I made a change, you say is not: the transformer once measured capacity can be transferred to the secondary side or three times, such as three winding 50000KVA main transformer, 100/100/100, is the primary capacity can be all to the two Secondary use, you can also use all the three times, which is mainly and the main transformer winding, clip and so on factors
Q:Sichuan transformer manufacturer that a best?
Sichuan Meishan New Transformer Co., Ltd.'s products have the strongest load capacity, up to 200%
Q:Transformer Wiring and Principle
Three-phase transformer works: the basic working principle of the transformer is the principle of electromagnetic induction. When the AC voltage is applied to the primary winding, the AC current flows into the winding to generate the excitation effect, and the alternating magnetic flux is generated in the iron core. The alternating magnetic flux passes through the primary winding and passes through the secondary winding , Which induces the induced electromotive force in the two windings, respectively. At this time if the secondary side and the external circuit load connected, there will be AC ​​current out, so the output power.
Q:Why 21 lighting transformers must use double-winding safety isolating transformers,
Double-winding type safety isolation transformer load side and the power supply side is not electrically connected, is safe, and autotransformer primary shared a winding, it has a direct electrical connection with the power supply, unsafe.
Q:How to increase the transformer output current
1, in the case of load, increase the load, multi-access electrical equipment, you can increase the output current.
Q:What is the meaning of the transformer 'turns ratio'? what's the effect?
The turns ratio of the transformer is the ratio of the transformer, that is, the ratio of the turns of the original coil and the secondary coil. Role: reflects the original transformer, vice coil voltage RMS ratio. In the case where the no-load current is negligible, the magnitude of the original and secondary coil current is inversely proportional to the number of turns. transformer 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:Transformer ratio and transformer ratio
Transformer ratio K and transformer voltage on both sides U1 U2 winding turns N1 N2 current I1 Ⅰ2 have a relationship! In the ideal case, the ratio K = U1 / U2 = N1 / N2 = I2 / I1
Q:Transformer if the boost and buck current will change?
Completely correct transformer output power = input power x efficiency, However, this refers to the rated voltage and rated current The actual output current of the transformer is determined by the load.
Q:2500KVA transformer rated current 3608A, how much can be overloaded current?
Transformer: 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). In electrical equipment and wireless circuits, commonly used as lifting voltage, matching impedance, safety isolation and so on. The main functions are: voltage conversion, current conversion, impedance conversion, isolation, voltage regulator (magnetic saturation transformer) and so on. According to the use can be divided into: distribution transformers, power transformers, sealed transformers, modular transformers, dry-type transformers, oil-immersed transformers, single-phase transformers, electric transformers, rectifier transformers.
