1. What is a transformer?
In AC circuits, the equipment that increases or decreases the voltage is called a transformer. The transformer can convert any voltage value into the voltage value we need with the same frequency to meet the transmission, distribution and use requirements of electric energy.
For example, the electricity generated by a power plant has a low voltage level. The voltage must be increased before it can be transported to distant power consumption areas. The power consumption areas must then reduce the voltage to an appropriate voltage level to supply power equipment and daily electricity. Equipment.
2. How does a transformer convert voltage?
Transformers are made based on electromagnetic induction. It consists of an iron core made of silicon steel sheets (or silicon steel sheets) and two sets of coils wound around the iron core. The iron core and the coils are insulated from each other and have no electrical connection.
It has been theoretically confirmed that the voltage ratio between the primary coil and the secondary coil of the transformer is related to the turns ratio between the primary coil and the secondary coil, which can be expressed by the following formula: primary coil voltage/secondary coil voltage = primary coil turns/secondary coil turns Explain that the more turns, the higher the voltage. So it can be seen that the secondary coil is less than the primary coil and that is the step down transformer. The opposite is a step-up transformer.
3. What types of transformer designs are there?
There are single-phase and
three-phase transformers according to the number of phases.
According to the purpose, they are divided into power transformers, special power transformers, voltage regulating transformers, measuring transformers (voltage transformers, current transformers), small power transformers (for small power equipment), and safety transformers.
According to the cooling method, it is divided into oil-immersed type and air cooling type.
4. What parts are the transformer components made of?
Transformer components are mainly composed of iron cores and coils, as well as oil tanks, oil pillows, insulating bushings and tap ends.
5. What are the uses of transformer oil?
The functions of transformer oil are:
(1), insulation effect
(2), heat dissipation effect
