Description

Technical Field

[0001] The invention belongs to the technical field of bus ducts, and in particular relates to an adjustable segmented bus duct. Background Art

[0002] Bus duct is a closed metal device composed of copper and aluminum busbars, which is used to distribute high power to various components of the distributed system. It has increasingly replaced wires and cables in indoor low-voltage power transmission trunk line projects. Segmented bus duct is a power transmission device that divides the bus duct into several sections of equal length, and the sections are connected by connectors or insulating heads. Traditional bus ducts have the following defects: 1. Limited angle adjustment: Traditional segmented bus ducts are mostly connected with insulated heads at fixed angles. During installation, it is necessary to prejudge the wiring path and customize corner accessories, which leads to a long construction period and high cost. In addition, it has poor adaptability in complex wiring scenarios (such as non-standard corners and curved paths). 2. Lack of temperature control function: The existing bus duct lacks an active temperature control system. The bus board is prone to insulation aging due to high temperature when running at high load for a long time, or the conductivity decreases in low temperature environment, which poses a safety hazard. 3. Low installation efficiency: Traditional installation mechanisms rely on the splicing of multiple parts and manual calibration, which are prone to deviation during the hoisting process and require repeated adjustments, which is time-consuming and labor-intensive; Therefore, it is necessary to design an adjustable segmented bus duct to solve the above problems.

[0019] Further, refer to Figures 1 to 10 , insulating layers 152 are arranged on the outer surfaces of both the busbar plate 15 and the inserting plate 23. The bottom of the connecting groove 151 and the connecting protrusion 231 are respectively connected to the busbar plate 15 and the inserting plate 23.

[0020] As can be seen from the above description, the present invention has the following beneficial effects: during use, the fixed plug board 43 is fixedly connected to the connecting board 21, and at the same time, the plugging board 23 and the bus bar 15 are connected to each other through the connecting groove 151 and the connecting protrusion 231. When horizontally connecting through the two fixing holes 24, one fixing hole 24 can be selected for connection and rotated at any angle as needed, making the segmented connection more stable and convenient.

[0021] Embodiment 2: Please refer to Figures 1 to 10 As shown, on the basis of Embodiment 1, the present invention provides a technical solution: the temperature control mechanism 5 includes a heat exchange plate 57 installed between the bus bars 15, a heat dissipation structure and a heating structure installed on both sides of the bus bar body 1. The heat dissipation structure includes a heat dissipation circulation box 51 installed on the side plate 11, a circulation pump 59 installed in the heat dissipation circulation box 51, and a heat dissipation channel 52 installed on the heat dissipation circulation box 51. A heat sink 53 is arranged on one side of the heat dissipation channel 52. The heat exchange plate 57 is connected to the circulation pump 59 in the heat dissipation circulation box 51. When the temperature is too high, the circulation pump 59 in the heat dissipation circulation box 51 operates to extract the medium in the heat dissipation channel 52 and the heat exchange plate 57 to circulate, and the heat dissipation is accelerated through the heat sink 53. The heating structure includes a heating circulation box 54 installed on the other side of the side plate 11, a circulation pump 59 installed in the heating circulation box 54, and a heating channel 55 installed on the heating circulation box 54. The flow rate of the circulation pump 59 is 5 - 10 L / min. A heating pipe 56 is arranged inside the heating channel 55. The circulation pump 59 in the heating circulation box 54 is connected to the heat exchange plate 57. When the temperature is too low, the medium in the heating channel 55 is heated by the heating pipe 56, and then is extracted by the circulation pump 59 in the heating circulation box 54 and enters the heat exchange plate 57, so as to heat the bus bar 15 through the heat exchange plate 57. An installation hole 571 is arranged in the middle of the heat exchange plate 57, and the installation bolt 14 passes through the installation hole 571. Support columns 572 are arranged on the inner side of the heat exchange plate 57. The support of the support columns 572 prevents the heat exchange plate 57 from being deformed by force, thus ensuring more convenient circulation of the internal medium. A connection port 573 is arranged on one side of the heat exchange plate 57. The heat exchange plate 57 is connected to the connecting pipe 58 through the connection port 573. One end of the connecting pipe 58 is connected to the circulation pump 59, which is convenient for the heat exchange plate 57 to be connected to the circulation pump 59 through the connecting pipe 58 during use. The heat conduction mechanism 50 includes heat dissipation protrusions 504 arranged on the surface of the heat exchange plate 57, a heat conduction graphite film 502 installed on one side of the heat exchange plate 57, and a heat conduction fiber film 501 installed on the heat conduction graphite film 502. An installation slot 503 is arranged on one side of the heat dissipation protrusions 504, and one side of the heat conduction graphite film 502 is clamped inside the installation slot 503. During use, the horizontal heat conduction of the heat conduction graphite film 502 and the rapid heat conduction of the heat conduction fiber film 501 are used to accelerate heat transfer, thereby accelerating the heat dissipation efficiency.

[0022] The temperature control mechanism 5 adopting the above technical solution exchanges heat through the heat exchange plate 57 installed between the busbars 15 during use. The circulating pump 59 in the heat dissipation circulation box 51 operates to make the heat exchange medium flow between the heat dissipation channel 52 and the heat exchange plate 57 for heat dissipation, or the circulating pump 59 in the heating circulation box 54 operates to make the heat exchange medium flow between the heat exchange plate 57 and the heating channel 55 and is heated by the heating pipe 56, thereby controlling the temperature of the busbar 15 and avoiding the influence of high temperature or low temperature on the performance of the busbar 15.

[0023] Further, reference can be made to Figures 1 to 10 , the installation mechanism 3 includes an installation main frame 31. The busbar main body 1 and the connection mechanism 2 are both installed inside the installation main frame 31. An installation pressing plate 32 is arranged on the upper side of the installation main frame 31. The installation pressing plate 32 presses on the busbar main body 1 and the connection mechanism 2. Installation screw rods 33 are rotatably installed at both ends of the installation main frame 31. Installation seats 34 are slidably installed at both ends of the installation main frame 31 through chutes. The installation seats 34 are screwed onto the installation screw rods 33 through downward pressing screw holes 35. The installation seats 34 are fixedly connected to the installation pressing plate 32 through installation screw holes 36 and screws. During use, it is hoisted by installing the installation main frame 31 on the outer sides of the busbar main body 1 and the connection mechanism 2, and then the installation pressing plate 32 is installed on the installation seats 34. By rotating the installation screw rods 33, the installation seats 34 and the installation pressing plate 32 are driven to press down on the busbar main body 1 and the connection mechanism 2 for limit installation.

[0024] The installation mechanism 3 adopting the above technical solution supports and holds the connection mechanism 2 and the busbar main body 1 during use and hoists them to the use position, and then drives the installation seats 34 and the installation pressing plate 32 to press on the connection mechanism 2 and the busbar main body 1 through rotating the installation screw rods 33 for limit fixation, which is more convenient to use.

[0025] Working principle and usage process of the present invention: During use, it is hoisted by installing the main frame 31 on the outer sides of the bus bar body 1 and the connecting mechanism 2. Then, the mounting pressure plate 32 is installed on the mounting seat 34, and by rotating the mounting screw 33, the mounting seat 34 and the mounting pressure plate 32 are driven to press down on the bus bar body 1 and the connecting mechanism 2 for limit installation. When the bus bar bodies 1 are connected in series, one end of the bus bar plate 15 is inserted between the plug-in plates 23, and is electrically connected by the engaging of the connecting protrusion 231 inside the connecting groove 151. The fixed plug plate 43 is inserted inside the connecting plate 21, and the connecting protrusion 231 and the connecting groove 151 are engaged for power connection. Then, the fixing bolt 25 passes through the fixing hole 24 to fix between the plug-in plate 23 and the bus bar plate 15. And when connecting in a straight line, it can be strengthened by two fixing holes 24 and fixing bolts 25. When a turn is needed, a single fixing hole 24 and fixing bolt 25 are installed and bent into the required angle according to needs. During installation and use, it can adapt to various angles for more convenient use. And during use, the external temperature will affect the use of the bus bar plate 15. The temperature sensor can be used to sense the temperature inside the bus bar body 1. When the temperature is too high, the circulation pump 59 in the heat dissipation circulation box 51 operates to extract the medium in the heat dissipation channel 52 and the heat exchange plate 57 for circulating flow, and the heat dissipation fins 53 are used to accelerate heat dissipation to the outside. When the temperature is too low, the heating pipe 56 heats the medium in the heating channel 55, and then the circulation pump 59 in the heating circulation box 54 extracts it and enters the heat exchange plate 57, so as to heat the bus bar plate 15 through the heat exchange plate 57, thereby ensuring that the bus bar plate 15 can be used within a suitable temperature range and avoiding the influence of high temperature and low temperature on it.
