Description

Technical Field

[0001] The utility model relates to a dry-type transformer with an anti-falling stable structure, belonging to the technical field of dry-type transformers. Background Art

[0002] A dry-type transformer is a special type of transformer whose core and windings are not immersed in insulating oil but instead are made of other insulating materials. This type of transformer has a wide range of applications and significant advantages. The following is a detailed introduction to dry-type transformers: A dry-type transformer, also known as a dry-type power transformer, is a transformer that does not rely on insulating oil for insulation. It primarily consists of an iron core, windings, insulation material, and a casing. The iron core is typically made of laminated silicon steel sheets, while the windings are wound with copper or aluminum wire, isolated and protected by insulating material. The operating principle of a dry-type transformer is based on the law of electromagnetic induction. When alternating current flows through the primary coil (high-voltage side), an alternating magnetic field is generated. A secondary coil (low-voltage side) surrounds the primary coil. When the current in the primary coil changes, an induced electromotive force is generated in the secondary coil, generating a voltage across the secondary coil. By adjusting the turns ratio between the primary and secondary coils, the voltage can be increased or decreased.

[0003] Authorization announcement number (CN208690054U) discloses a single-phase dry-type transformer with a stable structure. The transformer comprises a chassis and an iron core. The chassis has feet mounted on both sides of its bottom surface, with support plates fixed to the sides of the feet. A foam pad is provided inside the bottom of the chassis, and a bottom terminal box is located above the foam pad. Mounting plates are fixed to both sides of the bottom terminal box, with a fixing rod located in the middle of the mounting plates. A primary coil is provided on the left side of the iron core, positioned above the bottom terminal box. A secondary coil is mounted on the right side of the iron core, and a top terminal box is located above the iron core. Connecting pipes are provided on both sides of the top terminal box, and a circuit breaker is mounted above the top terminal box. Screws are provided on the front of both the bottom and top terminal boxes. This single-phase dry-type transformer with a stable structure is equipped with a foam pad and a protective door to facilitate the installation of internal components. The transformer is also moisture-resistant.

[0004] However, during use, the above-mentioned dry-type transformer may lack measures to prevent the coil group from falling off and stabilize and reinforce it. Since the coil group is prone to loosening during operation, the coil group is affected during operation and cannot bring convenience to the user, thereby affecting the overall stability and reliability of the dry-type transformer and increasing maintenance costs.

[0005] Therefore, a dry-type transformer with an anti-falling and stable structure is proposed. Utility Model Content
