Power transformer is a static electrical equipment, which is used to change the AC voltage (current) of a certain value into another voltage (current) with the same frequency or several different values.
Transformer is a static electrical equipment used to transform AC voltage and current to transmit AC energy. It realizes electric energy transmission according to the principle of electromagnetic induction. Transformers can be divided into power transformers, test transformers, instrument transformers and transformers for special purposes: power transformers are necessary equipment for power transmission and distribution and power user distribution; The test transformer is used to conduct withstand voltage (step-up) test on electrical equipment; Instrument transformer is used for electrical measurement and relay protection of distribution system (PT, CT); Transformers for special purposes include furnace transformers for smelting, welding transformers, rectifier transformers for electrolysis, small voltage regulating transformers, etc.
Power transformer is a static electrical equipment, which is used to change the AC voltage (current) of a certain value into another voltage (current) with the same frequency or several different values. When the primary winding is connected with AC, alternating magnetic flux is generated. The alternating magnetic flux induces AC electromotive force in the secondary winding through the magnetic conduction of the iron core. The secondary induced electromotive force is related to the number of turns of the primary and secondary windings, that is, the voltage is directly proportional to the number of turns. The main function is to transmit electric energy. Therefore, the rated capacity is its main parameter. Rated capacity is a customary value of power, which represents the size of transmitted electric energy, expressed in KVA or MVA. When the rated voltage is applied to the transformer, the rated current that does not exceed the temperature rise limit under specified conditions shall be determined according to it. The more energy-saving power transformer is amorphous alloy core distribution transformer. Its biggest advantage is that the no-load loss value is very low. Whether the no-load loss can be ensured is the core problem to be considered in the whole design process. When arranging the product structure, in addition to considering that the amorphous alloy core itself is not affected by external forces, the characteristic parameters of the amorphous alloy must be accurately and reasonably selected in the calculation.
