Description

An Applicable Power Transformer

technical field

The utility model relates to the technical field of transformers, in particular to an applicable power transformer.

Background technique

A power transformer is a static electrical device that is used to change an AC voltage (current) of a certain value into another voltage (current) with the same frequency or several different values. When the primary winding is supplied with 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 represents the size of the transmitted electric energy, 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. During use, the voltage transformer needs to be placed in the transformer box, and the transformer is protected by the transformer box.

However, in the actual use process, because the power consumption is changing at any time rather than fixed, especially in office places, agricultural places and other places, there are obvious peaks and valleys of power consumption, but because the transformer is easy to fix, it will cause the transformer to appear Overload, light load or even no-load conditions will not only cause losses to the transformer, but also cause waste of electricity. At the same time, the existing transformers are inconvenient to move and transport, and do not have good adaptability to complex and uneven installation surfaces. .
