Description

Technical Field

[0001] This utility model relates to the field of busbar installation technology, and in particular to an insulation support structure for busbars in a distribution cabinet. Background Technology

[0002] Busbars are the name of conductive materials used in power distribution equipment. They are made of flat copper (similar to electrical wires) without an insulation layer. They are painted with color indicating the phase sequence or fitted with sleeves of the corresponding color. They are mainly used to connect indoor transformers to distribution cabinets, then to the main power switch, and finally to various branch switches. A Chinese utility model patent, authorized announcement number "", discloses a double-insulated busbar support device. By setting up insulating connecting blocks, insulating cavities, second ventilation holes, and heat-conducting ceramic blocks, it is easy to form a double insulation effect with the insulating ceramics. This avoids the situation where the insulating ceramics fail to provide insulation support when they are damaged, as the copper busbars are supported by insulating ceramics alone. The device improves the electrical insulation at the support point. At the same time, the heat-conducting ceramic blocks make the heat distribution uniform, and then the device is cooled by natural airflow, which reduces thermal fatigue damage and improves the practicality of the device.

[0003] The above-mentioned technical solution only uses simple grooves on the insulating support to initially fix the busbar. Since the simple grooves lack effective limiting and positioning structures, the busbar is easily affected by vibration and external impact during installation. This may cause the already unstable busbar to shift further, aggravating the installation deviation. The position of the busbar needs to be recalibrated, thus affecting the installation efficiency of the busbar. Therefore, we propose an insulating support structure for the busbar of the distribution cabinet. Utility Model Content

[0004] The purpose of this utility model is to at least solve one of the technical problems existing in the prior art, and to provide an insulation support structure for the busbar of a distribution cabinet. This structure can solve the problem that simply opening a simple groove on the insulation support to initially fix the busbar is not enough. Because the simple groove lacks an effective limiting and positioning structure, the busbar is easily affected by vibration and external impact during installation. This can cause the already unstable busbar to shift further, exacerbating the installation deviation. The position of the busbar needs to be recalibrated, which affects the installation efficiency of the busbar.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an insulation support structure for a distribution cabinet busbar, comprising:

[0006] A supporting base plate is provided, and multiple primary ventilation holes are provided on the supporting base plate;

[0007] The cable tray positioning structure is located on the support base plate;

[0008] The cable tray positioning structure includes an insulating connecting frame and an insulating ceramic. The insulating connecting frame is fixedly installed on the support base plate by bolts. The insulating ceramic is fixedly connected to the top of the insulating connecting frame. The top of the insulating ceramic has multiple mounting slots and multiple threaded holes. The insulating ceramic is fixedly connected to multiple rotating seats. Each of the multiple rotating seats has a rotating rod rotatably connected inside. Each of the multiple rotating rods has a limit plate fixedly sleeved on its outer surface.

[0009] Preferably, the line positioning structure further includes multiple screws, and the top of each of the multiple limiting plates is provided with a through hole. Each of the multiple screws passes through the interior of the corresponding through hole and is threadedly connected to the corresponding threaded hole.

[0010] Preferably, the top of the support base plate is provided with two insulating pads, both of which are located between the insulating connecting frame and the support base plate, and both insulating pads are fixedly installed on the top of the support base plate by bolts.

[0011] Preferably, the insulating connecting frame has multiple heat dissipation fins fixedly connected inside, and the multiple heat dissipation fins are arranged in a linear array inside the insulating connecting frame.

[0012] Preferably, an insulating electroplated layer is fixedly connected to the top of the supporting base plate.

[0013] Preferably, the top of the insulating connecting frame has multiple second ventilation holes.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. The busbar insulation support structure of this distribution cabinet, through the threaded connection of the screw and the threaded hole, together with the setting of the rotating rod and the limit plate, can accurately and firmly limit and fix the busbar. When subjected to vibration or external force collision, the limit plate can tightly press the busbar, effectively preventing its displacement, avoiding repeated calibration work caused by the position deviation of the busbar, thereby improving the installation effect of the busbar.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

The use of terms like "first" and "second" is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the quantity or sequence of the indicated technical features.

[0026] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0027] Please see Figure 1-5 This utility model provides a technical solution: an insulation support structure for a distribution cabinet busbar, comprising:

[0028] A supporting base plate 1 is provided, and multiple first ventilation holes 7 are provided on the supporting base plate 1;

[0029] A line bar positioning structure is located on the support base plate 1;

[0030] The cable tray positioning structure includes an insulating connecting frame 3 and an insulating ceramic 4. The insulating connecting frame 3 is fixedly installed on the support base plate 1 by bolts. The insulating ceramic 4 is fixedly connected to the top of the insulating connecting frame 3. The top of the insulating ceramic 4 is provided with multiple mounting grooves 6 and multiple threaded holes 11. Multiple rotating seats 15 are fixedly connected to the insulating ceramic 4. Rotating rods 12 are rotatably connected inside the multiple rotating seats 15. Limiting plates 13 are fixedly sleeved on the outer surface of the multiple rotating rods 12. The cable tray positioning structure also includes multiple screws 14. The top of the multiple limiting plates 13 is provided with through holes 9. The multiple screws 14 pass through the interior of the corresponding through holes 9 and are internally threaded to the corresponding threaded holes 11.

[0031] Two insulating pads 5 are provided on the top of the support base plate 1. Both insulating pads 5 are located between the insulating connecting frame 3 and the support base plate 1. Both insulating pads 5 are fixedly installed on the top of the support base plate 1 by bolts.

[0032] Multiple heat dissipation fins 8 are fixedly connected inside the insulating connecting frame 3. The multiple heat dissipation fins 8 are arranged in a linear array inside the insulating connecting frame 3. An insulating electroplated layer 2 is fixedly connected to the top of the supporting base plate 1. Multiple second ventilation holes 10 are opened on the top of the insulating connecting frame 3.

[0033] Furthermore, when using this device, during the installation of the busbar in the distribution cabinet, the limiting plate 13 is rotated around the rotating rod 12 within the rotating seat 15, causing the limiting plate 13 to move away from the top of the mounting groove 6, thereby placing the busbar in the mounting groove 6 on top of the insulating ceramic 4. Then, the limiting plate 13 is reset, and the screw 14 is passed through the through hole 9 on the top of the limiting plate 13 and internally threadedly connected to the threaded hole 11 on the insulating ceramic 4. By rotating the screw 14, the limiting plate 13 is limited and fixed, thus facilitating the limiting plate 13 to limit and fix the busbar, making it tightly pressed against the busbar, thereby firmly fixing the busbar in the mounting groove 6 and achieving precise positioning of the busbar.

[0034] During the operation of the distribution cabinet, the heat generated by the busbar is transferred to the insulating ceramic 4 and the insulating connecting frame 3. The heat dissipation fins 8 inside the insulating connecting frame 3 increase the heat dissipation area and accelerate the dissipation of heat. At the same time, the first ventilation hole 7 on the support base plate 1 and the second ventilation hole 10 on the top of the insulating connecting frame 3 form an air convection channel. Outside cold air can enter through the first ventilation hole 7, and after the heat is carried away by the heat dissipation fins 8, it is discharged through the second ventilation hole 10, effectively reducing the temperature around the busbar. The insulating electroplated layer 2 and the insulating gasket 5 play a double insulation role, preventing leakage between the support base plate 1 and the busbar, ensuring the safety of operators and the normal operation of the distribution cabinet.

[0035] Through the threaded connection between the screw 14 and the threaded hole 11, and with the setting of the rotating rod 12 and the limiting plate 13, the busbar can be accurately and firmly limited and fixed. When subjected to vibration or external force collision, the limiting plate 13 can tightly press the busbar, effectively preventing it from shifting, avoiding repeated calibration work caused by the deviation of the busbar position, and thus improving the installation effect of the busbar.

[0040] Insulating gasket 5: Located between insulating connecting frame 3 and supporting base plate 1, it further enhances insulation performance and also serves as a buffer.

[0041] Heat dissipation fins 8: Fixedly connected inside the insulating connection frame 3, increasing the heat dissipation area and accelerating the dissipation of heat generated during the operation of the busbar;

[0042] Rotating rod 12: Rotatably connected inside the rotating seat 15, serving as the shaft for the rotation of the limiting plate 13, facilitating the opening and closing of the limiting plate 13;

[0043] Limiting plate 13: It is fixedly sleeved on the outer surface of the rotating rod 12, and by rotating and fixing, it limits and fixes the busbar placed in the mounting groove 6;

[0044] Screw 14: Passes through the through hole 9 at the top of the limiting plate 13 and is threadedly connected to the threaded hole 11 on the insulating ceramic 4 to achieve the limiting and fixing of the limiting plate 13;
