Description

Technical Field

[0001] The present application relates to the technical field of transformer cores, and in particular to a heat dissipation transformer core assembly. Background Art

[0002] With the development of the electric power industry, transformers are indispensable equipment in power transmission and transformation systems, and their stable operation is crucial to the safety of the entire power grid.

[0003] When the transformer is working under high load, the iron core and winding generate a lot of heat. The traditional transformer iron core that uses oil cooling or air cooling lacks an effective heat dissipation structure inside, so it can only take away the heat from the outer surface of the iron core body. The heat generated inside the iron core body can only be dissipated by the step-by-step transfer of silicon steel sheets, resulting in poor heat dissipation capacity of the iron core body, which can easily lead to overheating of the equipment due to insufficient heat dissipation, affecting the insulation performance and even causing failures. Utility Model Content

[0004] The problem to be solved by the present application is that the existing transformer core lacks an effective heat dissipation structure inside, which causes the core to overheat due to insufficient heat dissipation when the transformer is running at high load, thereby affecting the insulation performance.

[0005] In order to solve the above technical problems, the present application provides a heat dissipation type transformer core assembly, including a core body composed of multiple silicon steel sheets stacked together, and clamping assemblies for clamping and fixing the core body are arranged around the core body, and hoisting assemblies for facilitating the hoisting operation of the core assembly are symmetrically arranged on the upper part of the clamping assembly, and a heat dissipation assembly capable of improving internal heat dissipation is arranged inside the core body.

[0006] Since the core assembly of the present application is designed with a clamping assembly, a hoisting assembly and a heat dissipation assembly, the clamping assembly can be used to effectively fix the core body, the hoisting assembly can be used to hoist and transport the core assembly, and the heat dissipation assembly can be used to dissipate heat inside the core body, thereby solving the problem that the transformer core in the prior art lacks an effective heat dissipation structure, which causes the core to overheat due to insufficient heat dissipation when the transformer is running at high load, thereby affecting the insulation performance.

[0017] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application. Example

[0018] The present application relates to a heat dissipation transformer core assembly, such as Figure 1-6 As shown, the core assembly includes a core body 3 composed of multiple silicon steel sheets stacked together, a support block 4 for supporting the core body 3 is arranged at the bottom, and clamping assemblies 2 for clamping and fixing the core body 3 are arranged around the core body 3. In order to facilitate the lifting operation of the core assembly, a lifting assembly 1 for lifting the core assembly is symmetrically arranged on the upper part of the clamping assembly 2. In order to effectively improve the heat dissipation capacity of the core assembly, a heat dissipation assembly capable of improving internal heat dissipation is arranged inside the core body 3.

[0019] The clamping assembly 2 includes a clamping frame 7, a first pull rod 10, and a second pull rod 9. The clamping frame 7 is arranged around the outer side of the core body 3. In order to effectively fix the core body 3 with the help of the clamping frame 7, the clamping blocks are connected by the horizontal first pull rod 10 and the vertical second pull rod 9 respectively.

[0020] The hanging assembly 1 includes a hanging plate 6 and a third tie rod 8. The hanging plate 6 is arranged on the upper part of the clamping frame 7 at the top of the core body 3. In order to improve the hanging strength of the hanging plate 6, the hanging plate 6 and the clamping frame 7 are connected by a vertically arranged third tie rod 8.

[0021] The heat dissipation component is a square plate-shaped core plate 5 which is clamped inside the core body 3 . In order to effectively fix the core plate 5 , the core plate 5 is supported and positioned by first horizontally placed tie rods 10 around the core plate 5 .

[0022] In order to improve the heat dissipation capacity of the core body 3 with the help of the core plate 5, grooves 11 are evenly arranged along the vertical direction on the surface of the core plate 5, so that insulating oil or air can enter the core body 3 along the grooves 11 and effectively take away the heat generated inside the core body 3.

[0023] In order to further improve the heat dissipation capability of the core board 5 , the grooves 11 are symmetrically arranged on the upper portions of the front and rear surfaces of the core board 5 . Example

[0024] Based on the first embodiment, Figure 7 As shown, in order to facilitate the loading and unloading of the core plate 5 and realize the effective flow of the insulating oil or air inside it, the number of core plates 5 is two, which are arranged symmetrically up and down, and a channel 12 is left at the midline position in the width direction. Example

[0025] Based on the first embodiment, Figure 8 As shown, in order to facilitate the loading and unloading of the core plate 5 and to achieve effective flow of insulating oil or air therein, the number of core plates 5 is four, which are symmetrically arranged up and down and left and right, and channels 12 are left at the midline positions in the width direction and the length direction. Example

[0026] Based on the first embodiment, Fig. 9 As shown, in order to effectively reduce the weight of the core body 3 , straight slots 13 of different sizes are provided in the length and width directions of the core plate 5 .

[0027] When in use, the arrangement of the clamping assembly 2 can realize effective position fixing operation of the core body 3, and the lifting assembly 1 can facilitate the lifting and transportation operation of the core assembly. The core plate 5 arranged inside the core body 3 can realize effective flow of insulating oil or air by means of the grooves 11 and channels 12 on the upper part thereof, so that the insulating oil or air can take away the heat generated inside the core body 3.
