1. What is a distribution transformer?

Distribution transformer refers to a static electrical device that transforms AC voltage and current according to the law of electromagnetic induction and transmits AC power in a power distribution system.

In some areas, power transformers with a voltage level below 35 kV are called "distribution transformers". The place and place where the "distribution transformer" is installed is the substation. Distribution transformers should be installed on poles or on the ground in the open.

China's transformer products can generally be divided into UHV (750KV and above), ultra-high voltage (500KV) transformers, 220-110KV transformers, and 35KV and below transformers according to their 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 and below to directly supply power to end users.

When laying out the product structure, in addition to considering that the amorphous alloy core itself is not affected by external forces, it is also necessary to accurately and reasonably select the characteristic parameters of the amorphous alloy during calculation.

2. The application and function of distribution transformers

A power transformer is an electrical device used to change the magnitude of the AC voltage. A distribution transformer is a static electrical device that converts AC voltage and current to transmit electrical energy between two or more windings at the same frequency based on the principle of electromagnetic induction.

Distribution power transformer is a kind of static electrical equipment, which is used to change the AC voltage of a certain value into another voltage (current) with the same frequency or several different values.

When the primary winding of the distribution transformer passes through alternating current, alternating magnetic flux is generated, and the alternating magnetic flux induces an alternating electromotive force in the secondary winding through the magnetic conduction of the iron core.

The level of the secondary induced electromotive force is related to the number of turns of the primary and secondary windings, that is, the voltage is 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 for expressing power. It characterizes the size of the electric energy transmitted by the distribution transformer, expressed in kVA or MVA. When the rated voltage is applied to the transformer, it is used to determine the rated current that does not exceed the temperature rise limit under specified conditions.

The more energy-saving power transformer is an amorphous alloy core distribution transformer, and its biggest advantage is that the no-load loss value is extremely low. Whether the no-load loss value can be guaranteed in the end is the core issue to be considered in the entire design process.

The function of the distribution transformer is to step down the voltage. The distribution transformer converts the input 35kv or 10kV into the output 400V, and the distribution personnel of the power supply station will then select and connect according to the 380V or 220V required by the user.

Distribution transformer refers to a static electrical device that transforms AC voltage and current according to the law of electromagnetic induction and transmits AC power in a power distribution system. Distribution transformers are usually installed on poles or in power distribution stations, and can generally reduce the voltage from 6 to 10 kV to about 400 volts for input to users.
