Technical Field
[0001] This utility model relates to the field of busbar installation technology in prefabricated substations, and more specifically, to a multifunctional adjustable busbar copper busbar cover. Background Technology
[0002] Copper busbar covers are protective devices applied around copper busbars. Copper busbars are high-current conductive products, and their exposure poses a significant safety hazard. While ensuring adequate insulation distance, using copper busbar covers can prevent personal injury to workers due to misoperation and eliminate safety hazards. Copper busbar covers consist of a low-voltage side copper busbar cover, busbar frame, inverter side copper busbar cover, copper busbar cover plate, and sealing gaskets.
[0003] Currently, copper busbar protective covers on the market mainly fall into two categories. One is a single, non-adjustable sheet metal cover for the copper busbar. This type of cover is prone to assembly difficulties due to design margins and processing / assembly errors, often resulting in assembly failures and reprocessing, leading to cost waste and low assembly efficiency. The other type is an adjustable-length corrugated tube copper busbar cover. Because the cover needs to be fitted with busbars, which are highly heat-generating components, this type of cover requires high-temperature resistant corrugated tubes, resulting in higher costs. Furthermore, the corrugated tube material is relatively soft and cannot secure rigid copper busbars. Given these reasons, it is essential to design a simple, easy-to-operate, and adjustable busbar copper busbar cover structure.
[0004] The technical problem to be solved by the present invention is to provide a multifunctional adjustable busbar copper bus cover, which effectively solves the assembly difficulties caused by design margin or processing error, and solves the problem of meeting the multifunctional needs of users. Utility Model Content
[0005] To solve the above-mentioned technical problems, this utility model is a multifunctional adjustable busbar copper bus cover, including an inverter side cover. A low-voltage side cover is provided on the inner wall of the inverter side cover. A support block is provided at the bottom of the inverter side cover. An adjustment component is provided on the top of the side wall of the support block. The adjustment component includes a lead screw, with a knob at one end. A movable plate is threaded to the outer circumference of the lead screw. A limit rod is provided on the top of the side wall of the movable plate. A limit hole is opened at one end of the side wall of the inverter side cover. Sliding grooves are opened on both sides of the inner wall of the inverter side cover. Sliding rails are provided on both sides of the low-voltage side cover. A heat dissipation component is provided at the bottom of the low-voltage side cover. Multiple busbar copper buses are provided on the inner wall of the low-voltage side cover. A busbar frame is provided on the inner wall of the low-voltage side cover, and the multiple busbar copper buses pass through the busbar frame.
[0006] Furthermore, the heat dissipation assembly includes a temperature sensing probe, an air inlet is provided at the bottom of the low-pressure side cover, a fan is provided inside the air inlet, an air outlet is provided at the bottom of the inverter side cover, a ventilation plate is provided inside the air inlet, multiple heat dissipation holes are provided at the top of the ventilation plate, and the fan is electrically connected to an external power supply.
[0007] Furthermore, the top and side walls of the inverter side cover and the top and side walls of the low-voltage side cover are all provided with sealing gaskets, and the side walls of the sealing gaskets are provided with cover plates.
[0008] Furthermore, the fan sidewall is provided with a mounting plate, and the top of the mounting plate has multiple screw holes.
[0009] Furthermore, the bottom of the fan and the interior of the heat dissipation holes are filled with dustproof cotton, and the top of the inverter side cover and the low-voltage side cover are sealed with adhesive.
[0010] Furthermore, each of the multiple busbar copper busbars has a current transformer at one end of its outer wall, and the top of the inverter side cover and the low-voltage side cover are both welded from sheet metal parts.
[0011] The beneficial effects of this utility model are as follows: This utility model is a multi-functional adjustable busbar copper bus cover. Compared with the prior art, this utility model allows the operator to move the low-voltage side cover to the required position. The slide rail connected in the slide groove makes the adjustment of the multi-functional adjustable busbar copper bus cover more stable. By turning the knob, the screw is rotated, which causes the moving plate to move the limiting rod into the limiting hole, and then abuts against the low-voltage side cover for easy fixing. It can meet the installation of different specifications of busbar copper bus and different specifications of busbar frame, and solves the assembly difficulties caused by design margin and processing and assembly errors.
[0012] Secondly, the temperature of the busbar copper bus is detected by a temperature sensor. If the temperature is too high, the fan is started to dissipate the heat inside the cover through the heat dissipation holes in time, ensuring that the temperature rise of the busbar copper bus is within a reasonable range, and further protecting the safe operation of the transformer. The structural design of this utility model facilitates the installation of busbar copper bus and busbar frames of different specifications, and the assembly is simple and easy to dissipate heat.

The slide rail 17, which is slidably connected within the slide groove 16, facilitates smoother adjustment of the multi-functional adjustable busbar copper bus cover. By turning the knob 12, the lead screw 11 is rotated, which causes the moving plate 13 to move the limiting rod 14 into the limiting hole 15, and then abut against the low-voltage side cover 2 for easy fixing. This invention can meet the installation requirements of different specifications of busbar copper bus 7 and different specifications of busbar frame 6, and solves the assembly difficulties caused by design margins and processing and assembly errors.
[0020] Specifically, the heat dissipation component 5 includes a temperature sensor 18, an air inlet 19 at the bottom of the low-voltage side cover 2 with a fan 20 threaded inside the air inlet 19, an air outlet 21 at the bottom of the inverter side cover 1, a ventilation plate 22 fixed inside the air inlet 19, and multiple heat dissipation holes 23 on the top of the ventilation plate 22. The fan 20 is electrically connected to an external power supply. The temperature of the busbar copper bus 6 is detected by the temperature sensor 18. If the temperature is too high, the fan 20 is activated to dissipate the heat inside the cover through the heat dissipation holes 23 in a timely manner, ensuring that the temperature rise of the busbar copper bus 6 is within a reasonable range, further protecting the safe operation of the transformer.
[0021] Furthermore, sealing gaskets 8 are fixedly installed on the top and side walls of the inverter side cover 1 and the top and side walls of the low-voltage side cover 2, and cover plates 9 are threadedly connected to the side walls of the sealing gaskets 8.

[0027] The model number of fan 20 can be: 4-72-5 / A.
[0028] Working Principle: When the multi-functional busbar copper busbar cover needs adjustment, the operator moves the low-voltage side cover 2 to the desired position. The slide rail 17, slidably connected within the slide groove 16, facilitates smoother adjustment of the multi-functional adjustable busbar copper busbar cover. Turning the knob 12 rotates the lead screw 11, causing the moving plate 13 to move the limiting rod 14 into the limiting hole 15, thus abutting against the low-voltage side cover 2 for easy fixing. This allows for the installation of different specifications of busbar copper busbars 7 and busbar frames 6, solving assembly difficulties caused by design margins and processing / assembly errors. The temperature of the busbar copper busbar 6 is detected by the temperature probe 18. If the temperature is too high, the fan 20 is activated to cool the busbar. Heat inside the enclosure is dissipated promptly through the heat dissipation holes 23, ensuring that the temperature rise of the busbar copper bus 6 is within a reasonable range, further protecting the safe operation of the transformer substation. The sealing gasket 8 facilitates the improvement of the stability of the multi-functional adjustable busbar copper bus cover.
