Technical Field
[0001] This utility model relates to the field of transformer technology, specifically to a multi-stage damping short-circuit protection special transformer. Background Technology
[0002] A transformer is a device that uses the principle of electromagnetic induction to change alternating current voltage. Its main components are the primary coil, the secondary coil, and the iron core (magnetic core). Transformers are fundamental equipment for power transmission and distribution, and are widely used in industry, agriculture, transportation, urban communities, and other fields.
[0003] Existing transformers cannot isolate and protect the wiring points at the top of the transformer body during use, which greatly increases the possibility of debris falling onto the wiring points and causing short circuits, thus lacking short-circuit protection. In addition, they lack multi-stage damping, which makes them lack seismic resistance. Therefore, there is an urgent need for a special transformer with multi-stage damping for short-circuit protection to solve the above technical problems. Utility Model Content

An isolation cover is provided on the top of the transformer body. Two symmetrically arranged connecting blocks are connected to the bottom of the left and right sides of the isolation cover. Support blocks are connected to the left and right side walls of the transformer body and directly below the connecting blocks. The connecting blocks and support blocks are connected by fastening bolts and nuts. Openings are provided on the left and right side walls of the isolation cover. Fourteen dampers are provided at the bottom of the supporting base frame, and the bottoms of the fourteen dampers are connected to the bottom inner side of the supporting base frame.
[0007] As a preferred embodiment of this invention, both openings are rectangular in shape.
[0008] As a preferred embodiment of this utility model, the fourteen dampers are arranged in two rows, with seven dampers in each row, and the seven dampers in each row are arranged horizontally at equal intervals.
[0009] In a preferred embodiment of this invention, the bottom outer wall of the transformer body is in contact with the inner wall of the supporting frame, but the two are not connected.
[0010] As a preferred embodiment of this utility model, the number of mounting holes is set to four, and the four mounting holes are arranged in pairs opposite to each other about the two mounting bases.
[0011] As a preferred embodiment of this utility model, the isolation cover is in the shape of a cuboid structure.

It is to be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the utility model. Furthermore, it should be noted that, for ease of description, only the parts relevant to the utility model are shown in the accompanying drawings.

[0022] Please see Figure 1-4 A multi-stage damping short-circuit protection special transformer includes a transformer body 1. A supporting base frame 2 is fitted on the outer bottom of the transformer body 1. Mounting bases 3 are connected to both sides of the bottom of the supporting base frame 2. Mounting holes 4 are opened on both mounting bases 3. An isolation cover 8 is installed on the top of the transformer body 1. Two symmetrically arranged connecting blocks 6 are connected to the bottom of the left and right sides of the isolation cover 8. Support blocks 5 are connected to the left and right side walls of the transformer body 1 and directly below the connecting blocks 6. The connecting blocks 6 and the support blocks 5 are connected by fastening bolts 7 and nuts 11. By utilizing their mutual cooperation, the wiring points at the top of the transformer body 1 can be isolated and protected, greatly reducing the possibility of short circuits caused by debris falling at the wiring points at the top of the transformer body 1, thus providing short-circuit protection. Openings 9 are opened on the left and right side walls of the isolation cover 8. Fourteen dampers 10 are installed at the bottom of the supporting base frame 2, and the bottoms of the fourteen dampers 10 are all connected to the bottom inner side of the supporting base frame 2.
[0023] Both openings 9 are rectangular in shape.
[0024] The fourteen dampers 10 are arranged in two rows, with seven dampers 10 in each row. The seven dampers 10 in each row are arranged horizontally at equal intervals. By setting up a supporting base frame 2 and multiple dampers 10, multi-level damping can be achieved, enabling the transformer to have seismic resistance.
[0025] The bottom outer wall of the transformer body 1 is in contact with the inner wall of the supporting frame 2, but the two are not connected, so that the transformer body 1 can move up and down along the inner wall of the supporting frame 2 when it is subjected to vibration.
[0026] The number of mounting holes 4 is set to four, and the four mounting holes 4 are arranged in pairs opposite to the two mounting bases 3. Setting four mounting holes 4 can achieve stable and secure installation.
[0027] The isolation cover 8 is rectangular in shape, which makes it easy to cover the entire top of the transformer body 1 inside it.
[0028] The working principle and usage process of this utility model are as follows: When installing the isolation cover 8, the four connecting blocks 6 and the four supporting blocks 5 are connected by four fastening bolts 7 and four nuts 11. By setting the isolation cover 8, the wiring point at the top of the transformer body 1 can be isolated and protected, which greatly reduces the possibility of debris falling into the wiring point at the top of the transformer body 1 and causing a short circuit, thus providing short circuit protection function.
[0029] By setting a supporting bottom frame 2 and multiple dampers 10, when the transformer body 1 is subjected to vibration, the multiple dampers 10 at the bottom can reduce the vibration, thereby achieving multi-level damping and enabling the transformer to have anti-vibration function.
[0030] The transformer is short-circuit resistant and shock resistant, giving it special characteristics. When the transformer body 1 is subjected to vibration, it can move up and down along the inner side wall of the supporting base frame 2. When installing the transformer, it can be installed smoothly and firmly through the four mounting holes 4 on the two mounting bases 3 at the bottom. The contents not described in detail in this specification are existing technologies known to those skilled in the art.
[0031] The above description is merely a preferred embodiment of this application and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the utility model involved in this application is not limited to the technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the inventive concept. For example, technical solutions formed by substituting the above features with (but not limited to) technical features with similar functions disclosed in this application.
