Abstract
Description
Technical Field
[0001] This utility model relates to the field of transformer technology, specifically to a transformer whose output terminals can be adjusted laterally. Background Technology
[0002] In power systems, transformers are crucial electrical devices whose performance and reliability directly affect the stability of power transmission and distribution. Among these components, the copper busbars, as key parts connecting the transformer coils to external circuits, play a vital role in the overall operation of the transformer.
[0003] Currently, traditional transformers generally use an integrated design for their copper busbars. This integrated busbar, after being connected to the coil, is directly fixed to the upper clamp, as disclosed in a dry-type transformer application (CN201210534637.X). This design has significant limitations; due to its integrated design, its position cannot be adjusted once installed. In actual power equipment installation and maintenance, situations often arise where the position of the copper busbar needs to be fine-tuned due to space constraints, line routing adjustments, etc. However, existing integrated copper busbars cannot meet this requirement. This not only increases the difficulty and complexity of installation but may also lead to electrical connection problems caused by improper busbar placement, affecting the normal operation of the transformer.
[0004] Therefore, developing a transformer with adjustable output terminal position has become an urgent problem to be solved in the field of transformer technology. The transformer with laterally adjustable output terminals provided in this application is a transformer. Utility Model Content

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0022] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.
[0023] This invention provides a transformer with laterally adjustable output terminals.
[0024] In this embodiment, refer to Figure 1-3 The transformer with laterally adjustable output terminals includes a bracket 1, an iron core 2 fixed on the bracket 1, a coil 3 disposed outside the iron core 2, an upper clamping plate 4 disposed at the upper end of the iron core, a lower clamping plate 5 disposed at the lower end of the iron core, and a copper busbar 6 connected to the coil. It also includes a junction box 7 and a conductive plate 8.
[0025] The copper busbar 6 includes a separately disposed connecting section 9 and a wiring section 10, and each of the connecting section 9 and the wiring section 10 is provided with a contact 11 at its end;
[0026] The junction box is provided with a plurality of long wiring slots 12 that penetrate the lower end face of the junction box at intervals;
[0027] The conductive piece is fixed on the inner wall of the wiring groove 12. The upper and lower ends of the conductive piece are provided with elastic contact strips 13. After the connecting segment and the wiring segment extend into the wiring groove, they are connected by contacting the contact strips on both ends of the conductive piece through the contact points. The connecting segment and the wiring segment can be adjusted in position along the length of the wiring groove.
[0028] In the above technical solution, the copper busbar is divided into a connection section and a connection segment. Conductivity between the two is achieved through the wiring slots and conductive plates in the junction box. The connection section and connection segment can be adjusted along the wiring slots. In practical use, their positions can be adjusted by sliding the connection section and connection segment. This solves the problem of the inability to adjust the position of the traditional integrated copper busbar, allowing for flexible adjustment of the busbar position during transformer installation and maintenance based on the actual spatial layout and line routing, reducing installation difficulty and complexity. The split design also allows for individual replacement of damaged connection segments, reducing maintenance costs and resource waste.
[0029] The conductive piece has elastic contact strips at both ends, which can ensure the stability of the electrical connection when the connection section and the wiring section slide.
[0030] Specifically, the wiring segment is provided with wiring holes 14.
[0031] In this embodiment, wiring holes are provided on the wiring segment to facilitate the connection of external lines to the wiring segment.
[0032] Specifically, a connection groove 15 is provided on one side of the junction box, and the connection groove 15 of the junction box is fitted into the step 16 of the upper clamping plate. A fixing screw hole 17 is provided on the junction box above the connection groove.
[0033] In this embodiment, the junction box is connected to the upper clamp plate via a connecting groove, and the two can be fixed together with fixing screws, making the connection between the junction box and the upper clamp plate more stable, enhancing the stability of the entire transformer structure, and facilitating installation and disassembly, as well as subsequent maintenance and repair work.
[0034] Specifically, the inner wall of the wiring groove is provided with a sliding groove 18 and an inlet groove 19 connected to the sliding groove 18, and the ends of the connecting section and the wiring terminal are provided with protrusions 20 that slide in cooperation with the sliding groove.
[0035] In this embodiment, the sliding engagement of the protrusion and the slide groove further ensures the smoothness and stability of the sliding of the connecting segment and the wiring segment within the wiring groove, preventing shaking or displacement during position adjustment and ensuring the reliability of the electrical connection. Simultaneously, an inlet groove is provided, allowing the protrusion of the connecting segment and the wiring segment to be aligned with the inlet groove before being inserted into the slide groove.
[0036] Specifically, the cross-sections of the groove and the protrusion are both dovetail structures or "T"-shaped structures.
[0037] In this embodiment, the dovetail structure or "T"-shaped structure can better restrict the movement direction of the protrusion in the groove and prevent the protrusion from coming out of the groove.
[0038] Specifically, the contact strip has an arc-shaped structure with "T"-shaped connecting ends 21 at both ends. The upper and lower ends of the conductive piece are provided with grooves 22, and the sides of the grooves are provided with "T"-shaped connecting slots 23 that connect with the aforementioned "T"-shaped connecting ends.
[0039] In this embodiment, the arc-shaped contact strip has better elasticity and contact performance, and can make close contact with the contacts of the wiring copper busbar to ensure good electrical conduction; the cooperation between the "T"-shaped connection end and the "T"-shaped connection groove makes the connection between the contact strip and the conductive piece more stable, improving the reliability and stability of the electrical connection.
[0040] Attention all technical personnel: Although this utility model has been described according to the specific embodiments above, the concept of this utility model is not limited to this utility model. Any modification that utilizes the concept of this utility model will be included within the scope of protection of this patent right.
