220kV Oil-Immersed HV Transformer - High-Quality Power Transformer by China Suppliers & Factory
Power Transformer
A power transformer is a static electrical device used to convert a certain value of AC voltage (current) into another or several different values of voltage (current) with the same frequency.
A transformer is a static electrical device used to transform AC voltage and current and transmit AC electrical energy. It achieves the transmission of electrical energy based on the principle of electromagnetic induction.
Electromagnetic Induction Principle
A static device with two or more windings, in order to transmit electrical energy, converts the AC voltage and current of one system into the voltage and current of another system through electromagnetic induction at the same frequency. Usually, the values of these currents and voltages are different.Transformer Classifications By Use
Transformers can be divided into power transformers, test transformers, instrument transformers, and special purpose transformers based on their specific applications:
Operation & Capacity Parameters
When alternating current is applied to the primary winding, alternating magnetic flux is generated. The alternating magnetic flux is induced in the secondary winding through the magnetic conduction effect of the iron core, resulting in an alternating electromotive force. The height of the secondary induced electromotive force is related to the number of turns in the primary and secondary windings, meaning the voltage is directly proportional to the number of turns.
Since the main function of a power transformer is to transmit electrical energy, its rated capacity serves as its main parameter. Rated capacity is a commonly used value to represent power, characterizing the size of transmitted electrical energy expressed in kVA or MVA. When a rated voltage is applied to a transformer, it determines the rated current that does not exceed the temperature rise limit under specified conditions.
Energy Efficiency & Design Focus
The most energy-efficient power transformer is the amorphous alloy iron core distribution transformer. Its greatest advantage is having a particularly low no-load loss value. Ensuring this final no-load loss value is the core issue throughout the entire design process. When arranging the product structure, in addition to ensuring the amorphous alloy iron core itself is not subjected to external forces, it is necessary to accurately and reasonably select the characteristic parameters of the amorphous alloy during calculation.Frequently Asked Questions
