Embodiment Construction
[0035] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
[0036] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the relationship between the components in a certain posture (as shown in the accompanying drawings). Relative positional relationship, movement conditions, etc., if the specific posture changes, the directional indication will also change accordingly.
[0037] In addition, in t...

The invention discloses a dry-type transformer cooled by water circulation, which includes a transformer body, an outer casing and an air-cooled assembly; the transformer body includes an upper iron yoke, a lower iron yoke, an iron core, a fixing rod, a first Support base and coil assembly; the number of the iron core is 3; the upper iron yoke is located directly above the lower iron yoke; the three iron cores are vertically connected to the upper iron yoke and the Between the lower iron yokes, and the three iron cores are arranged at equal intervals; when the circulating water in the water channel flows through the evaporation water tank, under the action of the first axial flow fan, the heat is fully exchanged, and then flows into the water channel after the temperature drops In this cycle, the heat dissipation performance of the entire dry-type transformer is greatly improved.
Description
technical field [0001] The invention relates to the technical field of electrical equipment, in particular to a dry-type transformer cooled by water circulation. Background technique [0002] Compared with oil-immersed transformers, dry-type transformers refer to transformers whose iron core and windings are not immersed in insulating oil. Dry-type transformers are widely used in local lighting, high-rise buildings, airports, wharf CNC machinery and equipment and other places. [0003] Dry-type transformers have the advantages of good fire resistance, no toxic gas, flame retardant and self-extinguishing, low loss, low noise, no pollution, maintenance-free, and good insulation performance; however, dry-type transformers directly expose electrical components such as windings to In the outside world, oil-immersed transformers do not have the advantage of relying on mineral oil to dissipate heat. They can only rely on air convection to dissipate heat. However, dry-type transfor...
