Transformer knowledge
Transformer is the device that uses the principle of electromagnetic induction to change the AC voltage,and its main structural components are the primary coil, the secondary coil and core (magnetic core). The main functions are: voltage transformation, current transformation, impedance transformation, isolation, voltage stabilization (magnetic saturation transformer), etc.
Transformer consists of core(or magnetic core) and coil.Coil has two or more windings, the winding connected the power is called primary coil, the remaining windings are called secondary coil.It can transform AC voltage, current and impedance.The simplest core transformer is made of core produced by soft magnetic material and coil with two turns of different quantity on core.
Product Details
Cooling method
1)Dry type transformer: rely on air convection for natural cooling or increase fan to cooling, it is mostly used for small-capacity transformers for power utilization of high-rise buildings, high-speed toll station and local lighting, electronic circuits etc.
2)Oil-immersed transformer: rely on oil as cooling medium, such as oil-immersed natural cooling, oil-immersed air cooling, oil-immersed water cooling, forced oil circulation, etc.
