What is the difference between the power transformer and the power distribution transformer?
All transformers used in the power grid are referred to as the power transformer, which is a transformer for distribution, generally low pressure of 6 kV and or more.
The transformer reduces the grid voltage to the working voltage of the electrical equipment is referred to as a distribution transformer, which is used as a daily illumination and factory dynamic, generally low pressure of 0.4 kV and below.
The power distribution power transformer is a stationary electrical device that is a device (current) having a different value of alternating current voltage (current) varies the same frequency. When the winding is converted at an alternating current, an alternating magnetic flux is generated by a core magnetically magnetically promoted, an alternating electromotive force is in the secondary winding.
The high and low of the secondary induction electromotive force is related to the number of turns of the first winding, that is, the voltage magnitude is proportional to the number of turns. The main role is to transmit power, so the rated capacity is its main parameters.
The rated capacity is a conventional value of the power, which is characterized by the size of the transmission electrical energy, indicated by KVA or MVA, when applying a rated voltage to the transformer, determines the rated current of no temperature rise limit under predetermined conditions.
Nowadays, the power-saving power transformer is a stereoscopic iron core transformer and an amorphous alloy transformer. The maximum advantage is that the no-load loss is low.
In order to achieve the goal of carbon neutralization and carbon peaks, on June 1, 2021, China began implementing higher energy efficiency transformers, which reducing carbon emissions, and improving electricity utilization efficiency.
Liaocheng Huarui Electric Co., Ltd. is an export company integrated with the main business of the main business, the main product, the main product is the power distribution transformer, the main product is the power distribution transformer, medium and low voltage switchgear , Circuit breakers and other power distribution equipment and power engineering services.
