A three-phase dry-type transformer with convenient maintenance

Abstract

The invention, which relates to the technical field of transformers, discloses a three-phase dry type transformer being convenient to repair. The three-phase dry type transformer comprises a bottom plate; standing columns are fixedly connected to the four corners of the upper end of the bottom plate; a top plate is fixedly connected to one end, away from the bottom plate, of each of the four standing columns; and every two adjacent standing columns are connected with a side plate by a connecting mechanism. A cabinet door is installed on the wall of one side plate and is hinged to the side plates. A transformer is fixedly installed on the plate wall, close to the top plate, of the bottom plate. The connecting mechanisms include fixation blocks fixedly connected to the corresponding column walls of the standing columns; first clamp slots are formed symmetrically in one end, close to one side plate, of each fixation block; and a driving cavity is opened in the fixation block between everytwo first clamp slots. According to the three-phase dry type transformer, when the transformer in the cabinet is repaired, the side plates of the cabinet are dismounted rapidly to avoid maintenance influence by the side plates; the maintenance time is shortened; and the work efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of transformers, in particular to a three-phase dry-type transformer with convenient maintenance. Background technique [0002] With the rapid economic growth, all kinds of electrical equipment are continuously developed and applied to various occasions. Among them, dry-type transformers have become indispensable key equipment and are widely used in many occasions, such as airports, hospitals or shopping malls where a large amount of power supply is required. Compared with oil-immersed transformers, dry-type transformers are a kind of iron core and high-voltage line Transformers whose coils are not immersed in insulating liquid are generally used for local lighting and electronic circuits. With the continuous improvement of transformer users' requirements for transformers, the structure of transformers is becoming more and more complex, and the work efficiency is higher.
