Description

Technical Field

[0001] The utility model relates to the technical field of transformer production, and particularly relates to a new type of transformer mounting clamp. Background Art

[0002] In the iron core structure of a power transformer, the iron core is laminated by silicon steel sheets and usually has a "day" shape or a "square" shape, including vertical iron core columns and horizontal yokes (upper yoke and lower yoke). In order to ensure the stability of the iron core structure, reduce noise and vibration during operation, and effectively suppress the impact of huge electrodynamic force on the iron core during short circuit, special upper and lower clamps must be used to firmly clamp the upper and lower yokes; however, for existing iron core clamps such as a dry-type power transformer disclosed in the patent publication number CN119864223A, the device fixes the iron core through a top beam frame assembled by sequentially connecting long and short cross beams. This fixing method requires a large number of bolts for fixing and will consume a lot of time.

[0003] Therefore, the prior art needs to be further developed. Content of the Utility Model

[0004] The purpose of the utility model is to overcome the above technical deficiencies and provide a new type of transformer mounting clamp to solve the technical problem that in the related art, the iron core is fixed through a top beam frame assembled by sequentially connecting long and short cross beams, and this fixing method requires a large number of bolts for fixing and will consume a lot of time.

[0005] To achieve the above technical purpose, the utility model adopts the following technical solutions: A new type of transformer mounting clamp is provided, including: a first clamp; a second clamp, the second clamp is detachably connected to the first clamp, the second clamp is disposed opposite to the first clamp, and the second clamp and the first clamp enclose a clamping space to clamp the iron core laminations of the transformer.

[0006] Further, the first clamp includes: a first clamping arm, the first clamping arm is disposed on one side of the iron core lamination; two first connecting arms, the two first connecting arms are respectively disposed on the side of the first clamping arm facing the iron core lamination, and the two first connecting arms are respectively located on both sides of the iron core lamination; the second clamp includes: a second clamping arm, the second clamping arm is disposed on the side of the iron core lamination away from the first clamping arm; two second connecting arms, the two second connecting arms are respectively disposed on the side of the second clamping arm facing the iron core lamination, and the two second connecting arms are respectively located on both sides of the iron core lamination; the two second connecting arms are respectively detachably connected to the two first connecting arms.

[0007] Furthermore, each of the two first connecting arms has a first mounting space, and both first mounting spaces extend toward the direction of the iron core laminations; each of the two second connecting arms has a second mounting space, and both second mounting spaces extend toward the direction of the iron core laminations; the novel transformer mounting clamp also includes: a connector, at least a portion of which is located in the first mounting space and at least a portion of which is located in the second mounting space, the connector passing through the first mounting space and the second mounting space to connect two adjacent first connecting arms and second connecting arms.

[0008] Furthermore, the connector includes: a bolt, which passes through the first mounting space and the second mounting space; and a first nut, which is threadedly engaged with the bolt to connect two adjacent first connecting arms and second connecting arms.

[0009] Furthermore, the connector also includes a second nut, which is threaded into the bolt.

[0010] Furthermore, the new transformer mounting clamp also includes: a first reinforcing arm, which extends along the height direction of the core laminations and is disposed in a first mounting space, with the first reinforcing arm and the connector spaced apart; and a second reinforcing arm, which extends along the height direction of the core laminations and is disposed in a second mounting space, with the second reinforcing arm and the connector spaced apart.

[0011] Beneficial effects: 1. By using the separate relative arrangement and detachable connection of the first and second clamps, the iron core laminations can be quickly wrapped and clamped from both sides. Compared with the traditional structure that requires a large number of bolts to splice multiple short beams, the number of main connection points required is significantly reduced, thereby greatly simplifying the installation steps and shortening the assembly time.

[0012] 2. By setting a second nut on the bolt, a double-nut locking structure is formed in conjunction with the first nut. The mutual locking effect of the two nuts effectively prevents the loosening of a single nut due to continuous vibration or electrodynamic impact during transformer operation, greatly improving the vibration resistance and anti-loosening performance of the connector and ensuring the long-term stability of the clamping.

[0013] 3. By independently setting the first and second reinforcing arms in the first and second installation spaces respectively, and extending them along the height direction of the iron core laminations, the local stiffness and bending strength of the first and second connecting arms in the installation space area are significantly enhanced. The staggered arrangement of the reinforcing arms and the connecting parts allows the reinforcing arms to effectively share the bending moment and lateral force acting on the connecting arms, especially resisting the huge lateral impact generated by the short-circuit electrodynamics of the iron core laminations, preventing the connecting arms from deforming or breaking in the installation space, thereby improving the stability and safety of the entire clamping structure under extreme working conditions.

[0016] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0017] According to an embodiment of this utility model, a novel transformer mounting clamp is provided. Please refer to [link / reference]. Figures 1 to 2 It includes: a first clamp 1; a second clamp 2, the second clamp 2 being detachably connected to the first clamp 1, the second clamp 2 being disposed opposite to the first clamp 1, the second clamp 2 and the first clamp 1 forming a clamping space to clamp the core laminations 15 of the transformer.

[0018] By adopting the above technical solution, the first clamp 1 and the second clamp 2 are separately arranged and detachably connected, and the iron core lamination 15 can be quickly wrapped and clamped from both sides. Compared with the traditional structure that requires a large number of bolts to splice multiple short beams, the number of main connection points required is significantly reduced, thereby greatly simplifying the installation steps and shortening the assembly time.

[0019] Please refer to Figure 1The first clamping member 1 includes: a first clamping arm 3, which is disposed on one side of the iron core stack 15; and two first connecting arms 4, which are respectively disposed on the side of the first clamping arm 3 facing the iron core stack 15 and located on both sides of the iron core stack 15. The second clamping member 2 includes: a second clamping arm 5, which is disposed on the side of the iron core stack 15 away from the first clamping arm 3; and two second connecting arms 6, which are respectively disposed on the side of the second clamping arm 5 facing the iron core stack 15 and located on both sides of the iron core stack 15. The two second connecting arms 6 are detachably connected to the two first connecting arms 4. The first clamping arm 3, the first connecting arm 4, the second connecting arm 6, the second clamping arm 5, the other second connecting arm 6, and the other first connecting arm 4 are connected in sequence to form a clamping space.

[0020] By adopting the above technical solution, the first connecting arm 4 and the second connecting arm 6, as well as the first clamping arm 3 and the second clamping arm 5, arranged on both sides of the iron core lamination 15, together form a structurally stable and force-balanced closed clamping space. This effectively restricts the displacement of the iron core lamination 15 in multiple directions, improves the overall integrity and rigidity of the clamping, and helps to suppress noise, vibration, and resist short-circuit electrodynamics. At the same time, the design of the connecting arms on both sides facilitates installation and operation, and the connection points are located on the side, so as not to affect the winding space of the iron core lamination 15 in the vertical direction.

[0021] Please refer to Figure 2 The two first connecting arms 4 are respectively provided with first mounting spaces 7, and the first mounting spaces 7 extend toward the iron core lamination 15; the two second connecting arms 6 are respectively provided with second mounting spaces 8, and the second mounting spaces 8 extend toward the iron core lamination 15; the new transformer mounting clamp also includes: a connector 9, at least a part of the connector 9 is located in the first mounting space 7, at least a part of the connector 9 is located in the second mounting space 8, and the connector 9 passes through the first mounting space 7 and the second mounting space 8 to connect two adjacent first connecting arms 4 and second connecting arms 6.

[0022] By adopting the above technical solution and setting the first installation space 7 and the second installation space 8, space is provided for the connector 9 to connect the first connecting arm 4 and the second connecting arm 6 together, simplifying the installation process of the connector 9. At the same time, the connector 9, which runs through the structure of the connecting arms on both sides, provides strong shear resistance, effectively transmits clamping force, and ensures the reliability of the connection.

[0023] Please refer to Figure 2The connector 9 includes: a bolt 10, which passes through the first mounting space 7 and the second mounting space 8; and a first nut 11, which is threadedly engaged with the bolt 10 to connect two adjacent first connecting arms 4 and second connecting arms 6.

[0024] By adopting the above technical solution and using standardized bolts 10 and first nut 11 as connectors 9, a detachable and secure connection between the first connecting arm 4 and the second connecting arm 6 is achieved. This connection method is simple in structure, highly versatile, easy to apply and adjust clamping force, and easy to maintain and disassemble. Utilizing the characteristics of threaded engagement, a reliable connection and fixation can be achieved simply by tightening the first nut 11.

[0025] Please refer to Figure 2 The connector 9 also includes a second nut 12, which is threadedly engaged with the bolt 10.

[0026] By adopting the above technical solution, a second nut 12 is provided on the bolt 10, which cooperates with the first nut 11 to form a double-nut locking structure. Through the mutual locking effect of the two nuts, the loosening of a single nut caused by continuous vibration or electrodynamic impact during transformer operation is effectively prevented, greatly improving the vibration resistance and anti-loosening performance of the connector 9 and ensuring the long-term stability of the clamping.

[0027] Please refer to Figure 2 The new transformer mounting clamp also includes: a first reinforcing arm 13, which extends along the height direction of the core lamination 15 and is disposed in the first mounting space 7, with the first reinforcing arm 13 and the connector 9 spaced apart; and a second reinforcing arm 14, which extends along the height direction of the core lamination 15 and is disposed in the second mounting space 8, with the second reinforcing arm 14 and the connector 9 spaced apart.

[0028] By adopting the above technical solution, and by independently setting the first reinforcing arm 13 and the second reinforcing arm 14 in the first installation space 7 and the second installation space 8 respectively, and extending them along the height direction of the iron core lamination 15, the local stiffness and bending strength of the first connecting arm 4 and the second connecting arm 6 in the installation space area are significantly enhanced. The reinforcing arms are spaced apart from the connecting parts 9, so that the reinforcing arms can effectively share the bending moment and lateral force acting on the connecting arms, especially resisting the huge lateral impact generated by the short-circuit electrodynamics of the iron core lamination 15, preventing the connecting arms from deforming or breaking in the installation space, thereby improving the stability and safety of the entire clamping structure under extreme working conditions.

[0029] Working principle: The operator first places the first clamp 1 on one side of the transformer core lamination 15, so that the first clamping arm 3 is roughly parallel to the core lamination 15, and the two first connecting arms 4 are located on both sides of the core lamination 15. Next, the operator places the second clamp 2 on the opposite side of the core lamination 15, so that the second clamping arm 5 is opposite to the first clamping arm 3, and the two second connecting arms 6 are located on both sides of the core lamination 15 and aligned with the corresponding positions of the first connecting arms 4. Then, the operator passes the bolt 10 of the connector 9 through the first mounting space 7 on the first connecting arm 4 and the second mounting space 8 on the aligned second connecting arm 6, so that the first connecting arm 4 and the second connecting arm 6 fit tightly together. Subsequently, the operator tightens the first nut 11 at the protruding end of the bolt 10, initially connecting the first connecting arm 4 and the second connecting arm 6. The connecting arm 6 is fixedly connected; then, the second nut 12 is tightened at the same end or the other end of the bolt 10. The mutual locking action of the first nut 11 and the second nut 12 prevents a single nut from loosening and ensures a firm and reliable connection. During this process, the first reinforcing arm 13 set in the first installation space 7 and the second reinforcing arm 14 set in the second installation space 8 both extend along the height direction of the iron core lamination 15 and are spaced apart from the connector 9, effectively enhancing the rigidity and strength of the first connecting arm 4 and the second connecting arm 6 in the connection area. Finally, the first clamping arm 3, the two first connecting arms 4, the two second connecting arms 6, and the second clamping arm 5 together form a stable clamping space, firmly clamping the iron core lamination 15 and effectively suppressing its vibration, noise and short-circuit electrodynamic impact during operation.
