Description

A dry-type transformer that is easy to install

technical field

The utility model relates to the technical field of transformers, in particular to a dry-type transformer which is convenient for installation.

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.

Dry-type transformers are widely used in local lighting, high-rise buildings, airports, wharf CNC mechanical equipment and other places. Simply put, dry-type transformers refer to transformers whose iron core and windings are not immersed in insulating oil. Cooling methods are divided into natural air cooling (AN) and forced air cooling (AF). When naturally air-cooled, the transformer can operate continuously for a long time at the rated capacity. When forced air cooling, the output capacity of the transformer can be increased by 50%. It is suitable for intermittent overload operation or emergency accident overload operation; due to the large increase in load loss and impedance voltage during overload, it is in a non-economic operation state, so it should not be used for long-term continuous overload operation

However, the installation of the transformer is more difficult. In the designated position where it needs to be installed, the transformer is generally lifted above the mounting base by lifting equipment, and then adjusted many times until it is adjusted to the installation position, it can be installed and fixed. Therefore, in the process of hoisting, due to the large volume and weight of the transformer, it is difficult to quickly lift the installation position due to the large volume and weight of the transformer, which makes the whole installation process time-consuming and laborious, and the installation quality is not high. Therefore, there is an urgent need for a convenient installation. dry transformer.
