Based on the principle of electromagnetic induction. When the high voltage electrical energy flows through the high voltage coil, the resulting magnetic field creates a magnetic flux in the iron core. This magnetic flux willfurther induce the electronotive force in the low-voltage coil, thus converting high-voltage electrical energy into low-voltage electrical energy. Specifically, when the cylindrical transformer is connected to the power supply, due to the passage of current, magnetic flux will be generated in the coil, and this magnetic flux will pass through the magnetic circuit inside and outside the coil, and eventually form a magnetic link. Becausethe flux link inside the coil is generated by the current, it is called the self-inductance flux link or inductive flux link. When the number of turns of the two coils in the transformer is different, the voltage in the transformer will change, which is because the magnetic flux willproduce different voltages inside and outside the coil when it passes through the coil of different turns.
The structure of single-phase column transfomer mainly includes high voltage coil, low voltage coil, iron core and oil ank. The core has twvo kinds ofcylindrical and rectangular, of which the cylindrical core structure is relatively simple. The transformer is installed on the pilar of the power line, wvhich is easy to maintain and operate.
