Description

Technical Field

[0001] This utility model relates to the field of transformer stacked core technology, specifically a transformer stacked core with a stable support structure. Background Technology

[0002] The transformer core is one of the core components of a transformer, mainly used to form the transformer's magnetic circuit system. It is made up of multiple electrical steel sheets (also known as silicon steel sheets) stacked together, with each sheet insulated from the others to reduce eddy current losses.

[0003] Currently, after the transformer cores are stacked, clamping brackets are used to fix the cores. However, the clamping brackets are fixed with bolts, which cannot guarantee that the internal cores are under uniform pressure, affecting the stability of the cores during use. At the same time, the pressure stability of the cores can also be affected during transportation. Therefore, improvements are needed. Utility Model Content

[0012] Preferably, a support spring is fixedly connected to the bottom of the support block, and the lower end of the support spring is fixedly connected to the groove of the limiting top plate and the limiting side plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4This utility model provides a technical solution: a transformer core with a stable support structure, including a support base 1, a first support assembly 2 and a second support assembly 5 disposed on the support base 1, and locking bolts 22 connected to the top frame 21 and the bottom frame 24 of the first support assembly 2, one end of which is threadedly connected to the second support assembly 5. This locking bolt structure ensures the stability of the installation of the first support assembly 2 and the second support assembly 5. The first support assembly 2 and the second support assembly 5 have the same structure. The first support assembly 2 includes a bottom frame 24 integrally connected to the support base 1, and a limiting side plate 23 is disposed on the top side of the bottom frame 24. Multiple limiting side plates 23 are distributed horizontally at equal intervals about the top side of the bottom frame 24, providing protection. Multiple protective strips 25 are longitudinally and evenly spaced on the outer wall of the iron core 3 and the limiting side plate 23. The material of the protective strips 25 is fiberglass strap. This structure can bind the outer side of the iron core 3 through the protective strips 25 to prevent the iron core 3 from deforming, thereby improving the stability of the iron core 3 after installation. The top of the limiting side plate 23 is fixedly connected to the top of the limiting side plate 23. The inner side of the limiting side plate 23 clamps the iron core 3. The outer wall of the iron core 3 is bound with protective strips 25. The inner side of the top frame 21 is fixedly connected to the limiting top plate 26. The inner groove of the limiting top plate 26 and the limiting side plate 23 has an arc-shaped structure. A support pad 8 is inserted inside the groove. The support pad 8 is made of epoxy resin. This structure of the support pad 8 can hold the limiting top plate 26 and the limiting side plate when the pressure sensor 7 is not in use. The groove 23 is filled to prevent the groove from contacting the iron core 3 and causing deformation. Support blocks 9 are installed in the grooves inside the limiting top plate 26 and the limiting side plate 23. A lever plate 10 is fixedly connected to one side of the support block 9. This structure supports the pressure sensor 7 through the support block 9, allowing the top of the pressure sensor 7 to contact the surface of the iron core 3, facilitating the detection of the pressure on the iron core 3. The pressure sensor 7 is installed on the top of the support block 9, with its top surface attached to the iron core 3. This structure, through the pressure sensor 7, connecting wire 6, and portable pressure detector host 4, can detect the pressure applied to the iron core 3 by the limiting top plate 26 and the limiting side plate 23, thus ensuring uniform pressure throughout the iron core 3. In this configuration, a support spring 11 is fixedly connected to the bottom of the support block 9. The lower end of the support spring 11 is fixedly connected to the grooves of the limiting top plate 26 and the limiting side plate 23. This structure allows the support block 9 to be lowered by the support spring 11. At the same time, when the support block 9 is maintained at a certain height under the support of the support spring 11, the pressure sensor 7 can be stably installed inside the grooves of the limiting top plate 26 and the limiting side plate 23. Slots are provided on the inner sides of the limiting top plate 26 and the limiting side plate 23. The pressure sensor 7 is installed inside the slots. A connecting wire 6 is connected to the pressure sensor 7. One end of the connecting wire 6 is electrically connected to the portable pressure detector host 4. The portable pressure detector host 4, the pressure sensor 7 and the connecting wire 6 of this device are used for pressure detection.

[0024] Working principle: When using this transformer core stack with a stable support structure, first place the core 3 inside the limiting side plate 23 of the first support assembly 2, and then place the limiting side plate 23 of the second support assembly 5 on top of the core 3. Then, use the locking bolt 22 to connect the top frame 21 and the bottom frame 24 on the limiting side plates 23 of the first support assembly 2 and the second support assembly 5. During the pressure adjustment process, remove the support pad 8 from the groove inside the limiting top plate 26 and the limiting side plate 23. Then, insert the pressure sensor 7 into the groove inside the limiting top plate 26 and the limiting side plate 23, so that the pressure sensor 7 is placed on the support block 9, and the top of the pressure sensor 7 is in contact with the surface of the core 3. Then, turn on the portable pressure detector host 4 to detect the pressure, thereby adjusting the locking bolt 22 to a suitable pressure to avoid damage to the core 3.

[0025] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
