Description

Technical Field

[0001] This invention belongs to the field of busbar technology, specifically a smart heat dissipation busbar system made of low-impedance composite material. Background Art

[0002] Busbar trunking is a highly efficient and safe power transmission and distribution device, mainly composed of a metal shell, conductive busbars (copper or aluminum), insulation materials, and connectors. It is used to replace traditional cables in buildings or industrial sites to transmit high-current power. Through a closed metal structure, it distributes electrical energy from the distribution center to various electrical devices. It features high current carrying capacity, flexible installation, and convenient maintenance, and is widely used in modern building and industrial power systems. To improve the current transmission efficiency of the busbar, the materials are generally optimized, using low-impedance composite materials to reduce resistance during current transmission, thereby improving the busbar's current transmission efficiency and reducing heat generation. However, it has the following drawbacks:

[0003] When a fault occurs in one of the busbars in the busbar trunking, the resistance at that location increases, causing continuous heat generation. In this case, the cooling system cannot effectively dissipate heat at that location, which can easily damage the busbar. At the same time, it is inconvenient to detect the fault location, and troubleshooting is often time-consuming and labor-intensive. Summary of the Invention

[0013] Preferably, a fixed box is fixedly installed on the side of the connecting seat away from the installation area. One end of the pull rod extends into the interior of the fixed box.

[0014] Preferably, an oblique connecting pipe is provided between two adjacent connecting seats, and the oblique connecting pipe connects the first connecting pipe and the second connecting pipe of the two connecting seats to one side of each other, wherein the first connecting pipe of the connecting seat at one end is connected to a cold air fan.

The first switch on each branch is controlled by the controller as a whole, and the second switch on each branch is controlled individually by the controller.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1) During operation, the heat dissipation plate is set to correspond to the inner cavity. When the baffle rotates to the side of the second connecting pipe away from the first connecting pipe, the connecting seats are connected to each other, so that the bus body can be cooled as a whole. When the baffle rotates between the first connecting pipe and the second connecting pipe, it can cool the faulty part of the bus body separately, providing two different heat dissipation modes.

[0020] 2) During operation, when the baffle rotates between the first connecting pipe and the second connecting pipe, the baffle in the front connecting seat closes the opening of the connecting seat, and the subsequent connecting seats are closed by the baffle in this connecting seat. This allows for concentrated heat dissipation at the fault location of the busbar body, improving the protection effect of the busbar body, and facilitating the determination of the fault location, saving fault detection time.

[0021] 3) During operation, after tightening the set clamping screw, the end of the pressure plate with the temperature sensor is pressed against the heat sink. On the one hand, the heat sink is fixed, which facilitates the disassembly and maintenance of the heat sink. On the other hand, the temperature sensor is in close contact with the heat sink, and the heat conduction column is in close contact with the bus body, which makes the temperature sensor detect the temperature of the bus body more accurately.

[0022] 4) During operation, the heat dissipation plate, heat conduction column and heat dissipation inner plate are all made of ceramic material. Because ceramic material has thermal conductivity and insulation, it can dissipate heat from the busbar body while avoiding leakage accidents caused by the connection between the busbar body and the outside.

[0023] 5) During operation, the drive motor is connected in series with a first time delay relay and a second time delay relay, while the first time delay relay and the second time delay relay are connected in parallel. The power-off delay time of the first time delay relay is greater than that of the second time delay relay, so that the rotation angle of the baffle in the first mode is greater than that in the second mode, which facilitates the control of the rotation of the baffle.

Detailed Implementation

[0036] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0037] Depend on Figure 1-9 The present invention relates to an intelligent heat dissipation busbar trunking system of low impedance composite material, comprising a busbar trunking housing 1, grooves 2 equally spaced on the busbar trunking housing 1, a busbar body 3 made of low impedance composite material installed inside the grooves 2, a top heat conduction component 4 installed at the top of the busbar trunking housing 1, and a cold air heat dissipation component 5 installed at the top of the busbar trunking housing 1.

[0038] The top heat-conducting assembly 4 includes mounting areas 401 equidistantly arranged on the top of the busbar trunking housing 1. Each mounting area 401 includes equidistantly spaced connection holes 402 at the top of the busbar trunking housing 1, with each connection hole 402 penetrating into the interior of the trunking 2. Each mounting area 401 is equipped with a heat-conducting component, including a heat sink 403 positioned above the mounting area 401. Heat-conducting columns 405 are equidistantly installed at the bottom end of the heat sink 403, and each heat-conducting column 405 is inserted into the connection holes 402 on the mounting area 401. Insert plates 404 are symmetrically installed on both sides of one end of the heat sink 403. A longitudinally arranged baffle 508 closes one end of the heat sink 403. A slot 406 is provided inside the heat sink 403, which passes through both ends of the heat sink 403. Heat sink inner plates 407 are installed equidistantly inside the slot 406. The materials of the heat sink 403, the heat conduction column 405, and the heat sink inner plate 407 are all ceramic. Since the heat sink 403, the heat conduction column 405, and the heat sink inner plate 407 are all made of ceramic material, the ceramic material has thermal conductivity and insulation properties, which can prevent leakage accidents caused by the connection between the bus body 3 and the outside while dissipating heat from the bus body 3.

[0039] The cooling air heat dissipation assembly 5 includes connecting seats 501 equidistantly installed on the top of the busbar housing 1. The connecting seats 501 are used to dissipate heat from the heat-conducting components. Each connecting seat 501 corresponds to a mounting area 401. An inner cavity 504 is formed inside the connecting seat 501, and a baffle 508 is installed inside the inner cavity 504. A bottom rotating shaft 509 is installed at the bottom of the baffle 508, and the bottom rotating shaft 509 is rotatably connected to the connecting seat 501. A first connecting pipe 505 is installed on one side of the connecting seat 501, and a second connecting pipe 506 is installed on the other side of the connecting seat 501. When connected... When the connecting seat 501 rotates to the space between the first connecting pipe 505 and the second connecting pipe 506, it dissipates heat from a section of the busbar body 3. When the connecting seat 501 rotates to the other side of the second connecting pipe 506, it dissipates heat from the entire busbar body 3. The heat dissipation plate 403 corresponds to the inner cavity 504. When the baffle 508 rotates to the side of the second connecting pipe 506 away from the first connecting pipe 505, all the connecting seats 501 are interconnected, enabling overall heat dissipation from the busbar body 3. Between 06 and 06, it can dissipate heat at the fault location of the busbar body 3 alone, providing two different heat dissipation modes. The top of the inner cavity 504 is provided with an arc-shaped top wall 507. During the rotation of the baffle 508, the end face of the baffle 508 is in close contact with the surface of the arc-shaped top wall 507. A rotation drive component 511 is connected to the baffle 508. When the baffle 508 is in a vertical state, the baffle 508 is located on the side of the first connecting pipe 505 away from the second connecting pipe 506. A clamping and fixing component 510 is installed at the top of the connecting seat 501. The inner cavity 504 is close to the safety seat. A mounting groove 502 is provided on one side of the mounting area 401, and slots 503 are symmetrically provided on both sides of the mounting groove 502. When the baffle 508 rotates between the first connecting pipe 505 and the second connecting pipe 506, the baffle 508 closes the opening of the connecting seat 501 in front, and the subsequent connecting seats 501 are closed by the baffle 508 in this connecting seat 501. This allows for concentrated heat dissipation at the fault location of the bus body 3, improves the protection effect of the bus body 3, facilitates the determination of the fault location, and saves fault detection time.

[0040] The clamping fastener 510 includes two support plates 5101 symmetrically mounted on the top of the connecting seat 501. A pressure plate 5102 is disposed between the two support plates 5101. A central rotating shaft 5103 is mounted on the pressure plate 5102 and is rotatably connected to the support plates 5101. A temperature sensor 5104 is fixedly mounted on the bottom wall of the pressure plate 5102. The temperature sensor 5104 is located on the side of the central rotating shaft 5103 closer to the installation area 401. A horizontal plate 5105 is fixedly mounted on the side of the connecting seat 501 away from the installation area 401. A screw barrel is mounted on the horizontal plate 5105, and a clamping device is installed inside the screw barrel. The screw 5106 is longitudinally arranged, and the top of the screw 5106 contacts the bottom wall of the middle pivot 5103 of the pressure plate 5102 away from the installation area 401. After the screw 5106 is tightened, the end of the pressure plate 5102 with the temperature sensor 5104 is pressed against the heat sink 403. On the one hand, the heat sink 403 is fixed, which facilitates the disassembly and maintenance of the heat sink 403. On the other hand, the temperature sensor 5104 is in close contact with the heat sink 403, and the heat conduction column 405 is in close contact with the bus body 3, which makes the temperature detection of the bus body 3 by the temperature sensor 5104 more accurate.

[0041] The rotation drive component 511 includes a pull rod 5111 horizontally installed inside the inner cavity 504. The pull rod 5111 is located on the side of the baffle 508 away from the installation area 401. A connecting rod 5112 is hinged to one end of the pull rod 5111 near the baffle 508. One end of the connecting rod 5112 is hinged to the baffle 508. A fixing box 5113 is fixedly installed on the side of the connecting seat 501 away from the installation area 401. One end of the pull rod 5111 extends into the fixing box 5113. A slide plate 5114 is fixedly installed at one end inside the fixed box 5113. The slide plate 5114 is slidably connected to the fixed box 5113. A rotating screw 5115 is rotatably installed inside the fixed box 5113. The rotating screw 5115 is threadedly connected to the slide plate 5114. One end of the rotating screw 5115 is fixedly connected to the output shaft of the drive motor 5116. The drive motor 5116 is fixedly installed on the fixed box 5113 and is controlled by the control system.

[0042] An oblique connecting pipe 512 is provided between two adjacent connecting seats 501. The oblique connecting pipe 512 connects the first connecting pipe 505 and the second connecting pipe 506 of the two connecting seats 501 on the side close to each other. The first connecting pipe 505 of the connecting seat 501 at one end is connected to a cold air fan 513.

[0043] The control system consists of a data acquisition module, a data analysis and decision-making module, and an execution module. The data acquisition module is a temperature sensor 5104, the data analysis and decision-making module is a computer, and the execution module is a controller. The controller controls the drive motor 5116 through a control circuit.

[0044] The control circuit includes a power supply and various branches connected in parallel to the power supply. Each branch consists of a first time-delay relay 601, a first switch 602, a second time-delay relay 603, a second switch 604, and a drive motor 5116. The first time-delay relay 601 and the first switch 602 are connected in series to form a first small circuit; the second time-delay relay 603 and the second switch 604 are connected in series to form a second small circuit; the first and second small circuits are connected in parallel to form a third small circuit; and the third small circuit is connected in series with the drive motor 5116. The first switch 601 on each branch... 02 is controlled as a whole by the controller, and the second switch 604 on each branch is controlled individually by the controller. The drive motor 5116 is connected in series with the first time delay relay 601 and the second time delay relay 603. The first time delay relay 601 and the second time delay relay 603 are connected in parallel. The power-off delay time of the first time delay relay 601 is greater than the power-off delay time of the second time delay relay 603, so that the rotation angle of the baffle 508 in the first mode is greater than the rotation angle of the baffle 508 in the second mode, which facilitates the control of the rotation of the baffle 508.

[0045] Working principle: During installation, each heat sink 403 is installed sequentially above the installation area 401 at the top of the busbar housing 1, so that one end of the heat sink 403 is installed inside the installation slot 502, and the insert plate 404 is inserted into the inside of the slot 503. After installation, each heat conduction column 405 at the bottom of the heat sink 403 is inserted into each connection hole 402, so that the bottom end of the heat conduction column 405 contacts the busbar body 3. At this time, the vertically set baffle 508 closes one end of the slot 406.

[0046] Then, rotate the support plate 5101 until the temperature sensor 5104 on the support plate 5101 contacts the top wall of the heat sink 403. Then, tighten the clamping screw 5106. Since the clamping screw 5106 is threadedly connected to the horizontal plate 5105, the clamping screw 5106 moves upward, limiting the pressure plate 5102. This causes the end of the pressure plate 5102 with the temperature sensor 5104 to exert a downward clamping force on the heat sink 403, thus fixing the heat sink 403 on one hand and on the other hand... In this aspect, the temperature sensor 5104 is in close contact with the heat sink 403, and the heat conduction column 405 is in close contact with the bus body 3, so that the temperature sensor 5104 can detect the temperature of the bus body 3 more accurately. The materials of the heat sink 403, the heat conduction column 405 and the heat sink inner plate 407 are all ceramic. Ceramic materials have thermal conductivity and insulation, which can prevent the bus body 3 from being connected to the outside world and causing leakage accidents while dissipating heat from the bus body 3, and facilitate the disassembly, replacement and maintenance of the heat sink 403.

[0047] Under normal circumstances, the busbar body 3 generates heat when current flows through it. Since busbar body 3 is made of low-impedance composite material, heat generation is relatively infrequent. However, when the current is large, heat generation may still occur. When heat generation does occur:

[0048] In the first mode, temperature sensor 5104 monitors the temperature of heat sink 403, while heat conduction column 405 contacts busbar body 3, enabling temperature sensor 5104 to monitor the temperature of busbar body 3. When the temperature of busbar body 3 is high, temperature sensor 5104 transmits the detection result to the computer, which serves as a data analysis and decision-making module, for decision-making. The decision is then executed by the controller. At this time, the controller controls the cold air fan 513 to turn on and controls all the first switches 602 on each branch of the control circuit to close. At this time, all drive motors 5116 are turned on, causing the rotating screw 5115 to rotate, which moves the pull rod 5111 towards the fixed box 5113, pulling the baffle 508 to rotate. After the baffle 508 rotates to the delay time set by the first delay relay 601, the circuit is disconnected and the baffle 508 stops rotating. At this time, the baffle 508 rotates to the side of the second connecting pipe 506 away from the first connecting pipe 505. At this time, the cold air brought in by the cold air fan 513 enters each inner cavity 504 through the inclined connecting pipe 512 and blows out from the opening toward the heat sink 403. The heat sink 407 is installed at equal intervals in the slots 406 opened in the heat sink 403, which increases the heat exchange area between the air and the heat sink 403 and improves the heat dissipation effect. After the heat dissipation is completed, the first switch 602 is turned on and the direction of the drive motor 5116 connected to the circuit is reversed. At this time, the rotating screw 5115 rotates in the opposite direction, so that the baffle 508 returns to its original state.

[0049] In the second mode, when a section of busbar body 3 malfunctions, the temperature of this section of busbar body 3 will rise, and the temperature rise will be higher than that of other locations. At this time, when the data analysis and decision module receives the temperature detected by the corresponding temperature sensor 5104, which is higher than that of other locations, the controller controls the second switch 604 at the corresponding location to close, causing the corresponding drive motor 5116 to start and the baffle 508 to rotate. Under the action of the second time delay relay 603, the baffle 508 stops rotating when it is between the first connecting pipe 505 and the second connecting pipe 506. At this time, the air delivered by the cold air fan 513 passes through the first connecting pipe 506 of this connecting seat 501. After entering the inner cavity 504, the air cannot pass into the subsequent connecting seat 501 due to the obstruction of the baffle 508. In the connecting seats 501 in front, the baffle 508 remains vertical, so that all the air supplied is used to exchange heat with the heat sink 403 near the fault location of the bus body 3, which improves the protection of the bus body 3 and can remind the fault personnel of the location of the fault in the bus body 3, thereby saving the inspection time of the bus body 3 and improving maintenance efficiency. After the heat dissipation is completed, the second switch 604 is opened and the circuit connection direction of the drive motor 5116 is reversed. At this time, the screw 5115 is rotated in the opposite direction, so that the baffle 508 returns to its original state.

[0050] The delay time of the first delay relay 601 is greater than the delay time of the second delay relay 603, which makes the rotation angle of the baffle 508 in the first mode greater than the rotation angle of the baffle 508 in the second mode.
