Description

Technical Field

[0001] The utility model relates to the technical field of transformers, in particular to an external mounting frame for a dry-type transformer. Background Art

[0002] A transformer external mounting frame is a structure specifically designed for mounting transformers. It is designed to ensure the transformer is securely and stably positioned in a specific location while facilitating maintenance and inspection. This mounting frame typically consists of a base, a support platform, and fixed supports. The design of this mounting frame aims to improve the safety of transformer installation and maintenance, facilitate height adjustment, and prevent damage from collisions between the transformer and the fixed supports. External transformer mounting frames, particularly for outdoor installations, are typically installed in three different configurations: pole-mounted, pedestal-mounted, and floor-mounted, depending on the transformer's capacity, installation location, and ease of handling. The choice of these mounting methods depends on the specific installation environment and requirements to ensure the transformer's effective service to the power system. Furthermore, for safety, stability, and ease of maintenance, the fixed supports provide a cushioning effect during transformer placement, preventing damage from collisions between the transformer and the fixed supports. In addition, the installation method of the transformer external mounting frame includes base installation, support platform installation, size adjustment, transformer hoisting and height adjustment, ensuring the convenience and efficiency of the installation process.

The equipment of the present invention has a simple structure, adopts a cross-support method to make the transformer installation process more convenient, and uses a freely adjustable method so that a single person can also use the equipment to make the equipment in a horizontal state to facilitate the stable installation and support of the transformer support bracket. The above structure improves the efficiency of transformer installation, indirectly improves the installation work efficiency of personnel, and is conducive to the promotion of electricity use.

[0004] Similar to the above application, there are still the following deficiencies:

[0005] When the device is in the air for a long time during operation, some parts may become loose or even fall off, causing safety accidents. At the same time, when a fire occurs, the fire source will fall directly into the surrounding environment, causing a fire.

[0006] Therefore, in view of this, the existing structure and defects are studied and improved, and an external mounting frame for a dry-type transformer is proposed in order to achieve a more practical purpose. Utility Model Content

[0013] Furthermore, a connecting block is provided at the bottom of the mounting crossbar, and a supporting base plate is placed on the inner wall of the connecting block, and a mounting hole is opened inside the supporting base plate.

[0014] Compared with the prior art, the beneficial effect of the present invention is that the external mounting frame of the dry-type transformer adopts a protective structure, which can play an interception role and effectively prevent the parts on the upper end of the transformer from falling, thereby improving safety.

[0015] 1. The utility model can form a ring body connected to the electric pole through the clamping ring 1 and the clamping ring 2. At the same time, the positioning bolt can connect the clamping ring 1 and the clamping ring 2, and the limit bolt rod passes through the installation cross bars on the left and right sides in turn, which can improve the stability of the clamping ring 1 and the clamping ring 2. The connecting bolt is conveniently connected to the pull rope, so as to perform tension positioning on the four corners of the dry-type transformer. The snap connection between the clamping plate and the slot facilitates the assembly of the wire mesh. The wire mesh can be used to intercept and effectively prevent the dry-type transformer parts from falling off. At the same time, it can reduce the falling of the fire source when the dry-type transformer catches fire. BRIEF DESCRIPTION OF THE DRAWINGS
