Distribution transformer, abbreviated as "distribution transformer", refers to a static electrical appliance in the distribution system that transfers AC energy by converting AC voltage and current according to the law of electromagnetic induction. Some regions refer to power transformers with voltage levels below 35 kV (mostly 10KV and below) as' distribution transformers', abbreviated as' distribution transformers'. The place and location where "distribution transformers" are installed is not only a substation. Distribution transformers should be installed on columns or on the ground in the open air. It provides a detailed introduction to its installation method, installation precautions, supply and distribution methods, capacity selection, operation and maintenance, etc. Distribution transformer refers to a static electrical appliance used in the distribution system to transform AC voltage and current according to the law of electromagnetic induction and transmit AC energy. Chinese transformer products can generally be divided into ultra-high voltage (750KV and above), ultra-high voltage (500KV) transformers, 220-110KV transformers, and 35KV and below transformers based on voltage levels. Distribution transformers usually refer to power transformers operating in the distribution network with a voltage level of 10-35KV and a capacity of 6300KVA or below that directly supply power to end users. A distribution 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. When alternating current is applied to the primary winding, alternating magnetic flux is generated. The alternating magnetic flux, through the magnetic conduction of the iron core, induces alternating electromotive force in the secondary winding. The height of the secondary induced electromotive force is related to the number of turns in the primary and secondary windings, that is, the voltage is directly proportional to the number of turns. The main function is to transmit electrical energy, therefore, rated capacity is its main parameter. Rated capacity is a commonly used value to represent power, which represents the size of transmitted electrical energy, expressed in kVA or MVA. When applying rated voltage to a transformer, it is used to determine the rated current that does not exceed the temperature rise limit under specified conditions. The more energy-efficient power transformer is the amorphous alloy iron core distribution transformer, whose biggest advantage is that the no-load loss value is extremely low. Whether the ultimate no-load loss value can be ensured is the core issue to be considered throughout the entire design process. When arranging the product structure, in addition to considering that the amorphous alloy core itself is not subjected to external forces, it is also necessary to accurately and reasonably select the characteristic parameters of the amorphous alloy during calculation. The major domestic manufacturers of power transformers include TBEA, Shandong Mingda, and TBEA Luming Transformers
