Parameter:

Ano ang working principle sa unencapsulated Class H dry-type power transformer？

Key Components：

• Iron Core: Kasagaran gihimo sa laminated high-quality silicon steel sheets, nga may low loss ug low noise. Ang function sa iron core mao ang concentrate ug guide sa magnetic field, thus improving the efficiency of the transformer.

• Primary Winding: Connected to the high-voltage side, it receives the input voltage. The primary winding is usually wound with copper or aluminum wires.

• Secondary Winding: Connected to the low-voltage side, it outputs the required voltage. The secondary winding is also wound with copper or aluminum wires.

• Insulation Materials: H-class insulation materials such as NOMEX paper and fiberglass are used, which possess excellent heat resistance and electrical properties.

• Cooling System: Usually, natural air cooling (AN) or forced air cooling (AF) is adopted. The appropriate cooling method is selected according to specific application requirements.

Working Process：

• Input Voltage: The alternating current power source is applied to the transformer through the primary winding.

• Generating Magnetic Field: The current in the primary winding generates an alternating magnetic field in the iron core.

• Transferring Magnetic Field: The alternating magnetic field is transferred to the secondary winding through the iron core.

• Inducing Electromotive Force: The alternating magnetic field induces an electromotive force in the secondary winding, generating the output voltage.

• Output Voltage: The secondary winding outputs the required voltage for the load to use.
