Abstract
Description
Technical Field
[0001] The utility model relates to the field of transformer lead clamping, in particular to a transformer with a clamping component. Background Art
[0002] The current flowing through the transformer's low-voltage leads is high. Many large transformers use copper busbars to connect the low-voltage side of the transformer to the low-voltage bushing. The leads are typically supported by a clamping structure to ensure a safe distance between the leads and between the leads and the ground. The wooden components and the bolts securing them together form the lead bar fixing structure that secures the low-voltage lead bar. The transformer's copper busbar structure typically requires two bolts on each side for securement. This provides relatively poor security and is difficult to install, making it prone to displacement during installation. Utility Model Content

Therefore, features defined as "first", "second", etc. may explicitly or implicitly include one or more of the features. In the description of the present utility model, unless otherwise specified, "multiple" means two or more.
[0022] In the description of this application, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on specific circumstances.
[0023] To facilitate understanding of the present invention, a more comprehensive description of the present invention will be provided below with reference to the accompanying drawings. The accompanying drawings illustrate preferred embodiments of the present invention. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and comprehensive understanding of the disclosure of the present invention.
[0024] The utility model discloses a transformer with a clamping assembly, which comprises an iron core assembly, a clamping piece arranged on the iron core assembly, and a clamping assembly arranged on the clamping piece.
[0025] like Figure 1As shown, the clamping assembly includes a support assembly and a fixing assembly. The support assembly includes a fixing wood fixed to the clamp and a support plate 1 fixedly connected to the fixing wood. The fixing wood can be a horizontal or vertical wood connected to the clamp. The fixing assembly includes a copper busbar fixing member 2 and a lead fixing member 5 disposed on the support plate 1.
[0026] Among them, the copper busbar fixing part 2 is in a Lv-shaped structure, that is, the copper busbar fixing part 2 is provided with two copper busbar holes for fixing the copper busbar 4, and the two copper busbar holes are arranged in the vertical direction. Both copper busbar holes are long holes, that is, their cross-sections are rectangular, which can match the shape of the copper busbar 4. The copper busbar 4 can fit better with it and is more convenient to fix. In addition, at least two first mounting holes 3 are provided between the two copper busbars 4. In one embodiment of the present utility model, the number of the first mounting holes 3 on the copper busbar fixing part 2 is three, and the three first mounting holes 3 are evenly arranged in the horizontal direction. Combined Figure 1 and Figure 2 As shown, the first mounting holes 3 are connected to the insulating screws to securely connect the copper busbar fixing member 2 to the support plate 1. The copper busbar fixing member 2 is installed in a symmetrical manner with the support plate 1, completely surrounding and securing the two copper busbars 4 at the top and bottom, saving space. Furthermore, a row of first mounting holes 3 is provided in the middle of the copper busbar fixing member 2. Compared to traditional structures, this additional fixing hole increases the contact area between the support plate 1 and the copper busbar fixing member 2.
[0027] like Figure 1 As shown, the lead fixing member 5 is in a U-shaped structure, that is, the lead fixing member 5 is provided with an oblong hole for fixing the lead 7, the oblong hole corresponds to the cross-sectional shape of the lead 7, and two leads 7 can be inserted into the oblong hole. The lead fixing member 5 is also provided with a second mounting hole. In one embodiment of the present invention, the number of the second mounting holes is two, and the two second mounting holes are arranged in the horizontal direction and are arranged below the oblong hole. Figure 1 and Figure 2 The second mounting hole is connected with the insulating screw to fix the lead fixing member 5 to the support plate 1. This not only meets the insulation requirement to the ground, but also increases the contact area between the supporting wood piece and the circular wood piece.
[0028] In addition, the lead fixing member 5 is arranged on a side of the copper busbar fixing member 2 away from the clamp, which facilitates the arrangement of the copper busbar 4 and the arrangement of the lead wires 7 .
[0029] In the present invention, the copper busbar fixing member 2 and the lead fixing member 5 are both connected to the support plate 1 via insulating screws, which improves the insulation and reliability of the entire device and reduces safety hazards. The lead 7 passes through this position to avoid interference. This effectively increases the insulation distance between the copper busbar 4 and the fixing plate, that is, the creepage distance along the surface of the clamping member, which not only ensures the mechanical strength of the lead 7 but also meets the electrical distance requirements of the lead 7 without having to increase the size of the fuel tank. At the same time, it effectively increases the overall structural strength, saves space, can meet the installation and coordination requirements of the copper busbar 4 in different directions, and improves the convenience during installation.
[0030] The above embodiments merely illustrate several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the concept of the present invention, and these variations and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present utility model patent shall be determined by the appended claims.
