Description

Technical Field

[0001] This utility model relates to the field of transformer core technology, and in particular to a transformer core that is easy to install. Background Technology

[0002] A transformer is a device that uses electromagnetic induction to change AC voltage. It is mainly used for voltage transformation, current transformation, and voltage stabilization. In general, the simplest way to install a transformer core is to fix the core to a mounting frame with bolts, and use the bolted support structure to stabilize the stacked silicon steel sheets.

[0003] However, due to temperature changes during use, silicon steel sheets undergo slight deformation and displacement. While traditional bolt connections are simple and convenient for installation, they require the bolts to contact and press against the silicon steel sheets for fixation. This increases the contact force between the bolts and the sheets after slight deformation, potentially damaging the silicon steel sheet structure. Therefore, a transformer core design that is easy to install is urgently needed to address these problems. Utility Model Content

[0004] The purpose of this invention is to provide a transformer core that is easy to install, so as to solve the problems existing in the prior art and improve the fixing effect of the transformer core.

[0005] To achieve the above objectives, this utility model provides the following solution: This utility model provides a transformer core that is easy to install, comprising:

[0006] Iron core body;

[0007] A pair of first clamping plates and a pair of first connecting rods surround the top of the iron core body, and the two ends of the first connecting rods are respectively connected to the pair of first clamping plates;

[0008] A pair of second clamping plates and a pair of second connecting rods surround the bottom of the iron core body, and the two ends of the second connecting rods are respectively connected to the pair of second clamping plates;

[0009] A connecting assembly is disposed at the connection between the first connecting rod and the first clamping plate, and the second connecting rod and the second clamping plate. The connecting assembly defines a moving range on the first clamping plate and the second clamping plate. The first connecting rod and the second connecting rod are movably connected within the moving range. A pair of first connecting rods and a pair of second connecting rods respectively contact the top and bottom sides of the iron core body and have an elastic tendency in the opposite direction.

The positioning ring is limited to move within the annular groove, and an annular interval is provided between the outer ring side of the positioning ring and the inner sidewall of the annular groove.

[0012] An elastic element is disposed within the annular region. An adjacent first connecting rod or second connecting rod is passed through the center of the positioning ring. The positioning ring cooperates with the elastic element to give the first connecting rod or second connecting rod an elastic tendency to move away from the inner wall of the annular groove.

[0013] Preferably, the elastic element is a leaf spring, which is spirally wound around the outer ring of the positioning ring. The distance between the leaf spring and the center of the positioning ring gradually increases, and the maximum end of this distance abuts against the inner wall of the annular groove.

[0014] Preferably, mutually penetrating limiting holes are provided on both sides of the annular groove axis, and the diameter of the limiting holes is larger than the inner ring diameter of the positioning ring and smaller than the outer ring diameter of the positioning ring.

[0021] This invention relates to a core body with a pair of first clamping plates and a pair of first connecting rods, as well as a pair of second clamping plates and a pair of second connecting rods, arranged opposite each other to enclose and fix the top and bottom perimeters of the core body. A connecting assembly connects the two ends of the first connecting rods to the pair of first clamping plates, and the two ends of the second connecting rods to the pair of second clamping plates. The connecting assembly defines a movement range on the first and second clamping plates, allowing the first and second connecting rods to be elastically connected within this range.

Simultaneously, the defined movement range allows for adaptive displacement to support the movement of the first and second connecting rods when the core body undergoes slight deformation. This not only avoids structural damage to the silicon steel sheets due to excessive contact force but also maintains contact, improving the fixation effect on the core body.

Detailed Implementation

[0029] 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.

[0030] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] Reference Figures 1-5 This utility model provides a transformer core that is easy to install, comprising:

[0032] Iron core body 1;

[0033] A pair of first clamping plates 2 and a pair of first connecting rods 3 surround the top of the iron core body 1, and the two ends of the first connecting rods 3 are respectively connected to the pair of first clamping plates 2;

[0034] A pair of second clamping plates 4 and a pair of second connecting rods 5 surround the bottom of the iron core body 1, and the two ends of the second connecting rods 5 are respectively connected to a pair of second clamping plates 4;

[0035] A connecting assembly is provided at the connection between the first connecting rod 3 and the first clamping plate 2, and the second connecting rod 5 and the second clamping plate 4. The connecting assembly defines a moving range on the first clamping plate 2 and the second clamping plate 4. The first connecting rod 3 and the second connecting rod 5 are movably connected within the moving range. A pair of first connecting rods 3 and a pair of second connecting rods 5 respectively contact the top and bottom sides of the iron core body 1 and have an elastic tendency in the opposite direction.

[0036] This invention provides a system for securing the top and bottom perimeters of an iron core body 1 by arranging a pair of first clamping plates 2 and a pair of first connecting rods 3, as well as a pair of second clamping plates 4 and a pair of second connecting rods 5, in pairs opposite to each other. A connecting assembly connects the two ends of the first connecting rods 3 to the pair of first clamping plates 2 and the two ends of the second connecting rods 5 to the pair of second clamping plates 4. The connecting assembly defines a movement range on the first clamping plates 2 and 4, allowing the first connecting rods 3 and 5 to be elastically connected within this range. The first connecting rods 3 and 5 are stabilized by contact with the iron core body 1. Simultaneously, the defined movement range allows for adaptive displacement of the first connecting rods 3 and 5 when the iron core body 1 undergoes slight deformation. This not only prevents structural damage to the silicon steel sheets due to excessive contact force but also maintains contact, improving the fixation effect on the iron core body 1.

[0037] Specifically, a base frame 6 is welded to the bottom end of the second clamping plate 4 for mounting the iron core body 1.

[0038] Furthermore, the connection components include:

[0039] The positioning ring 7, the first clamping plate 2 and the second clamping plate 4 are respectively provided with annular grooves. The positioning ring 7 is limited to move within the annular groove, and an annular interval is provided between the outer ring side of the positioning ring 7 and the inner sidewall of the annular groove.

[0040] An elastic element is disposed within the annular region. An adjacent first connecting rod 3 or second connecting rod 5 is inserted through the center of the positioning ring 7. The positioning ring 7 cooperates with the elastic element to make the first connecting rod 3 or second connecting rod 5 have an elastic tendency to move away from the inner wall of the annular groove.

[0041] The positioning rings 7 are movably connected in the annular groove. Since the connecting components are set at the connection points of the first connecting rod 3 and the first clamping plate 2, as well as the connection points of the second connecting rod 5 and the second clamping plate 4, eight annular grooves are opened and eight positioning rings 7 are elastically connected in the annular grooves by elastic elements, providing the first connecting rod 3 and the second connecting rod 5 with elastic movement tendency. At the same time, through the set annular interval, the first connecting rod 3 and the second connecting rod 5 can generate adaptive displacement when the silicon steel sheet deforms.

[0042] Furthermore, the elastic element is a leaf spring 8, which is spirally wound around the outer ring of the positioning ring 7. The distance between the leaf spring 8 and the center of the positioning ring 7 gradually increases, and the maximum end of this distance abuts against the inner wall of the annular groove.

[0043] By winding a helical leaf spring 8 around the outer ring of the positioning ring 7, an elastic force is formed between the positioning ring 7 and the annular groove. This maintains the contact with the iron core body 1 during the adaptive displacement of the first connecting rod 3 and the second connecting rod 5, and can support the annular section, providing displacement space for the adaptive deformation of the first connecting rod 3 and the second connecting rod 5.

[0044] Furthermore, mutually penetrating limiting holes 9 are provided on both sides of the annular groove axis. The diameter of the limiting holes 9 is larger than the inner diameter of the positioning ring 7 and smaller than the outer diameter of the positioning ring 7.

[0045] The first connecting rod 3 and the second connecting rod 5, which pass through the positioning ring 7, are limited by the limiting hole 9, which provides the displacement distance of the first connecting rod 3 and the second connecting rod 5, and restricts the positioning ring 7 in the annular groove, maintaining the connection between the positioning ring 7 and the annular groove.

[0046] Furthermore, the top ends of the pair of first clamping plates 2 are provided with grooves in opposite directions, and the inner walls of the grooves are respectively provided with sliding grooves on opposite sides. Sliding blocks 10 are elastically connected in the sliding grooves, and mounting rods 11 are fixed between the two sliding blocks 10. The top end of the iron core body 1 is provided with a baffle 13, and the two ends of the baffle 13 are integrally formed and fixed with hooks 14. The two hooks 14 are respectively engaged with the two mounting rods 11 on the pair of first clamping plates 2. The two ends of the baffle 13 have a tendency to move in opposite directions.

[0047] In this technical solution, grooves are opened on a pair of first clamping plates 2, and springs 12 are fixed in the grooves. The two ends of springs 12 are fixed to sliders 10 and grooves, so that sliders 10 can drive the mounting rod 11 to slide elastically. By integrally forming hooks 14 at both ends of baffle 13, and by snapping the hooks 14 onto the mounting rod 11, combined with the supporting effect of springs 12, baffle 13 can generate adaptive displacement when silicon steel sheets undergo slight deformation. This stabilizes the iron core body 1 while avoiding damage to the silicon steel sheets. By mounting baffle 13 between a pair of first clamping plates 2 and abutting against the top surface of the iron core body 1, the fixing effect of the pair of first clamping plates 2 on the iron core body 1 is enhanced. Moreover, the installation method of baffle 13 is simple and convenient.

[0048] The baffle 13 is preferably, but not limited to, made of a metal material with a certain degree of elasticity.

[0049] Furthermore, a pair of first clamping plates 2 and a pair of second clamping plates 4 extend from both ends of the first connecting rod 3 and the second connecting rod 5, respectively, and a nut 15 is threadedly connected to the portion of the first connecting rod 3 and the second connecting rod 5 extending from the first clamping plate 2 and the second clamping plate 4.

[0050] In this technical solution, the diameter of the nut 15 is larger than that of the limiting hole 9. Simultaneously, threads are provided on the portions of the first connecting rod 3 and the second connecting rod 5 that extend beyond the first clamping plate 2 and the second clamping plate 4, respectively. Furthermore, when the nut 15 is threadedly fixed to the first connecting rod 3 and the second connecting rod 5, a gap is provided between it and the adjacent first clamping plate 2 and the second clamping plate 4. A washer 16 is placed within this gap and fitted onto the first connecting rod 3 or the second connecting rod 5. The washer 16 slides in contact with the adjacent first clamping plate 2 and the second clamping plate 4, providing a preload force to the nut 15, ensuring a stable threaded connection between the nut 15 and the first connecting rod 3 and the second connecting rod 5. The washer 16 also slides in contact with the first clamping plate 2 and the second clamping plate 4 when the first connecting rod 3 and the second connecting rod 5 are displaced.

[0051] Furthermore, it also includes:

[0052] There are several third connecting rods 17, which are distributed vertically around the outer perimeter of the iron core body 1. The two ends of the third connecting rods 17 are detachably connected to the first clamping plate 2 and the second clamping plate 4, respectively.

[0053] Specifically, a fixing plate 19 is integrally fixed to the outer side wall of the first clamping plate 2 and the second clamping plate 4, and a corresponding through hole is opened on the fixing plate 19 along the vertical direction. The two ends of the third connecting rod 17 pass through the two fixing plates 19 along the vertical direction, and a nut 15 is threadedly connected to the protruding part of the third connecting rod 17, so as to realize the connection and fixation of the first clamping plate 2 and the second clamping plate 4.

[0054] Furthermore, the first connecting rod 3, the second connecting rod 5, and the third connecting rod 17 are all covered with a buffer layer 18.

[0055] The buffer layer 18 can be made of a common plastic-coated material to provide a buffering effect in contact with the iron core body 1.

[0056] This utility model provides an easy-to-install transformer core installation procedure:

[0057] The iron core body 1 is placed between a pair of second clamping plates 4, and the iron core body 1 is supported by the base frame 6. A pair of first clamping plates 2 are arranged opposite each other on the top two sides of the iron core body 1. A pair of first connecting rods 3 and a pair of second connecting rods 5 are placed opposite each other on the two sides of the iron core body 1. The two ends of the first connecting rods 3 pass through the two positioning rings 7 on the pair of first clamping plates 2. Washers 16 are fitted on the protruding parts of the first connecting rods 3 and the second connecting rods 5. Then, nuts 15 are threaded and fixed to the first connecting rods 3 and the second connecting rods 5. The washers 16 slide in contact with the adjacent first clamping plates 2 and the second clamping plates 4. The positioning rings 7, leaf springs 8 and annular grooves provide the first connecting rods 3 and the second connecting rods 5 with elastic movement range to adapt to the slight deformation of the silicon steel sheet and protect the silicon steel sheet structure.

[0058] Finally, the two ends of the baffle 13 are hooked onto the two mounting rods 11, and the third connecting rod 17 is inserted between the two corresponding fixing plates 19 in the vertical direction. The first clamping plate 2 and the second clamping plate 4 are connected by threaded connection to complete the installation and fixing of the iron core body 1.
