Description

Technical Field

[0001] The utility model relates to the technical field of transformers, and more specifically, to a dry-type transformer. Background Art

[0002] Dry-type transformers are widely used in local lighting, high-rise buildings, airports, docks, CNC machinery and equipment and other places. Simply put, a dry-type transformer refers to a transformer whose core and winding are not immersed in insulating oil.

[0003] Some patent documents of dry-type transformers are disclosed in the prior art. The Chinese patent with application number CN202122744280.5 discloses a dry-type transformer, including a protective box, one side of which is rotatably connected with a box door, and a plurality of heat dissipation ports are provided on both sides of the protective box. The heat dissipation ports are rotatably connected with a closing plate, and the inner side of the top of the heat dissipation port is fixedly connected with an arc plate. The advantages of the utility model are that the lower part of the heat dissipation port is connected with the outside world, and the airflow enters from the lower part of the heat dissipation port and blows out from the heat dissipation fan, thereby improving the heat dissipation effect of the device. When the device body encounters a safety accident and explodes, the airflow generated by the explosion of the device body acts on the closing plate. Since the width of the upper end of the closing plate is greater than the width of the lower end, the upper end of the closing plate is subjected to a greater outward impact force, so that the closing plate rotates and contacts with the baffle to close the heat dissipation ports on both sides of the protective box, so that the device can block a large impact force when it explodes under the premise of having good heat dissipation performance.

[0004] In the above patent, the dust-proof effect of the transformer is poor when in use, resulting in excessive accumulation of dust inside the transformer, thereby affecting the service life of the transformer. For this reason, we propose a dry-type transformer. Utility Model Content
