Description

Technical Field

[0001] This utility model relates to the field of silicon steel sheet technology, and in particular to a silicon steel sheet for transformers. Background Technology

[0002] In power transformers, silicon steel sheets are used to make the core. The working principle of the transformer is based on the law of electromagnetic induction. The silicon steel sheet core can effectively concentrate and conduct magnetic fields, reducing energy loss. This enables the transformer to efficiently convert alternating current of one voltage level to alternating current of another voltage level, and it is widely used in power transmission and distribution systems.

[0003] The above-mentioned and existing technologies have the following drawbacks: During the operation of silicon steel sheets, a large amount of heat will accumulate inside them. Since silicon steel sheets are difficult to transfer heat to the outside, they are prone to causing high temperatures in the transformer, which will affect the normal operation of the transformer.

[0004] Therefore, a silicon steel sheet for transformers is proposed. Utility Model Content

[0005] The purpose of this invention is to address the drawback that silicon steel sheets are difficult to transfer heat to the outside, which can easily cause transformers to overheat and affect their normal operation. Therefore, this invention proposes a silicon steel sheet for transformers.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a silicon steel sheet for transformers, comprising a silicon steel sheet body, wherein mounting holes are formed on the surface of the silicon steel sheet body, and a heat collection plate is fixedly connected to the surface of the silicon steel sheet body, wherein the heat collection plate is a copper alloy plate, and a plurality of heat dissipation holes are formed on the surface of the heat collection plate.

[0007] The effect achieved by the above components is as follows: by setting up heat collection plates and heat dissipation holes, the heat inside the silicon steel sheet body will be transferred to the heat collection plates during the operation of the transformer. When air flows through the heat dissipation holes, it can carry away the heat inside the heat collection plates in time, thereby cooling the heat collection plates and then cooling the silicon steel sheet body, ensuring that the transformer can operate normally.

[0008] Preferably, a retaining strip is fixedly connected to the surface of the heat collection plate, and the retaining strip is fixedly connected to the silicon steel sheet body.

[0009] The effect achieved by the above components is that the retaining strip can improve the connection strength between the heat collection plate and the silicon steel sheet body.

[0010] Preferably, the surface of the silicon steel sheet body is covered with a protective sleeve.

[0011] The effect achieved by the above components is that the protective sleeve can shield the silicon steel sheet body and prevent the sharp tip of the silicon steel sheet body from causing wear to other silicon steel sheets body.

[0012] Preferably, the surface of the protective sleeve has pull holes.

[0013] The effect achieved by the above components is that the pull holes allow for easy movement of the protective cover.

[0014] Preferably, a friction strip is fixedly connected to the inner wall of the protective sleeve, and the friction strip is slidably connected to the silicon steel sheet body.

[0015] The effect achieved by the above components is that the friction strip can increase the friction between the silicon steel sheet body and the protective sleeve, thus preventing the protective sleeve from falling off.

[0016] Preferably, a protrusion is fixedly connected to the surface of the silicon steel sheet body, and a groove is formed on the surface of the silicon steel sheet body. The size of the protrusion matches the size of the groove, and one end of the protrusion has an arc-shaped structure.

[0017] The effect achieved by the above components is that when the protrusion on the surface of one silicon steel sheet engages with the groove on the surface of another silicon steel sheet, the engagement of the protrusion and the groove can improve the connection strength of the silicon steel sheet and prevent the sheets from falling apart.

[0018] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0019] In this invention, by setting up a heat collection plate and heat dissipation holes, the heat inside the silicon steel sheet body is transferred to the heat collection plate during the operation of the transformer. When air flows through the heat dissipation holes, it can carry away the heat inside the heat collection plate in time, thereby cooling the heat collection plate and then cooling the silicon steel sheet body, ensuring that the transformer can operate normally.

The surface of the silicon steel sheet body 1 has mounting holes 2. A heat collection plate 3, made of copper alloy, is fixedly connected to the surface of the silicon steel sheet body 1. The surface of the heat collection plate 3 has several heat dissipation holes 4. By setting the heat collection plate 3 and the heat dissipation holes 4, during transformer operation, the heat inside the silicon steel sheet body 1 is transferred to the heat collection plate 3. When air flows through the heat dissipation holes 4, it can promptly remove the heat inside the heat collection plate 3, thereby cooling the heat collection plate 3 and consequently cooling the silicon steel sheet body 1, ensuring the transformer can operate normally. A retaining strip 5 is fixedly connected to the surface of the heat collection plate 3, and the retaining strip 5 is fixedly connected to the silicon steel sheet body 1. The retaining strip 5 can improve the connection strength between the heat collection plate 3 and the silicon steel sheet body 1.

[0029] like Figures 1-5 As shown, a protective sleeve 6 is slidably fitted onto the surface of the silicon steel sheet body 1. The protective sleeve 6 can shield the silicon steel sheet body 1 and prevent the tip of the silicon steel sheet body 1 from causing wear on other silicon steel sheet bodies 1. The surface of the protective sleeve 6 has a pull hole 7, which allows the protective sleeve 6 to be moved easily. A friction strip 8 is fixedly connected to the inner wall of the protective sleeve 6. The friction strip 8 is slidably connected to the silicon steel sheet body 1. The friction strip 8 can increase the friction between the silicon steel sheet body 1 and the protective sleeve 6 and prevent the protective sleeve 6 from falling off. A protrusion 9 is fixedly connected to the surface of the silicon steel sheet body 1. A groove 10 is formed on the surface of the silicon steel sheet body 1. The size of the protrusion 9 is adapted to the size of the groove 10. One end of the protrusion 9 has an arc-shaped structure. When the protrusion 9 on the surface of one silicon steel sheet body 1 engages with the groove 10 on the surface of another silicon steel sheet body 1, the engagement of the protrusion 9 and the groove 10 can improve the connection strength of the silicon steel sheet body 1 and prevent the sheets from falling apart.

[0030] The overall working principle is as follows: before assembling the silicon steel sheet body 1, the protective sleeve 6 can shield the silicon steel sheet body 1 to prevent the tip of the silicon steel sheet body 1 from causing wear on other silicon steel sheet bodies 1. The pull hole 7 can facilitate the movement of the protective sleeve 6. The friction strip 8 can increase the friction between the silicon steel sheet body 1 and the protective sleeve 6 to prevent the protective sleeve 6 from falling off. The locking strip 5 can improve the connection strength between the heat collection plate 3 and the silicon steel sheet body 1. During the operation of the transformer, the heat inside the silicon steel sheet body 1 will be transferred to the heat collection plate 3. When the air flows through the heat dissipation hole 4, it can carry away the heat inside the heat collection plate 3 in time, thereby cooling the heat collection plate 3 and then cooling the silicon steel sheet body 1, ensuring that the transformer can operate normally. When the protrusion 9 on the surface of one silicon steel sheet body 1 engages with the groove 10 on the surface of another silicon steel sheet body 1, the engagement of the protrusion 9 and the groove 10 can improve the connection strength of the silicon steel sheet body 1 and prevent the sheets from falling apart.
