The steps to energize a power transformer are as follows:
a. Selection of a suitable transformer: First of all, you need to select a suitable transformer according to the voltage and current size required by the load. Generally speaking, the current allowed to pass through the transformer should be greater than the current required by the load, and the rated voltage of the load should be within the rated voltage range of the transformer.
b. Connect the power supply and load: Connect the positive pole of the power supply to one end of the main coil, and connect the load with the secondary coil to form an energized circuit.
c.Turn on the power supply: check whether the circuit is connected correctly before energizing, then turn on the power supply, the transformer can start to work. At this time, the magnetic field generated in the main coil converts the voltage into a voltage related to the turns ratio of the main and secondary coils and outputs it to the load.
In addition, attention is also required:
When carrying out transformer stopping and feeding operation, it should be carried out by two people, one operates and one supervises. When operating, it is necessary to use qualified insulating rod, the operator should wear a helmet. Rainy day operation should wear insulating boots and use insulating rod with rain cover.
When sending electricity, the high voltage side should be sent first, and then the low voltage side; when stopping electricity, the low voltage side should be stopped first, and then the high voltage side. The operation sequence of low voltage single-phase knife gate and high voltage falling fuse is as follows: first close the side phase which is closer to the middle phase, then close the other side phase, and finally close the middle phase.
If manual adjustment of the output voltage is required, the output voltage of the transformer can be adjusted by adding wires to the main or secondary coil and utilizing a tap.
When using a transformer, safety regulations such as wearing protective equipment, grounding, and avoiding overuse should always be followed to ensure safety.
