Abstract
Description
Technical Field
[0001] This utility model relates to the field of busbar trunking, and more specifically, to an automatic temperature-measuring high-density busbar trunking. Background Technology
[0002] Compact busbar trunking is a highly efficient power transmission device primarily used for distributing electrical energy in buildings or industrial facilities. Its compact internal structure tightly arranges the busbar conductors (usually copper or aluminum busbars), with the three-phase busbars separated by insulating partitions. These partitions typically use high-performance insulating materials such as epoxy fiberglass cloth, ensuring phase-to-phase insulation while effectively utilizing space and reducing the overall size of the busbar trunking.
[0003] Because current flowing through copper busbars generates heat, and the compact internal structure of high-density busbar trunking makes heat dissipation relatively difficult, excessively high copper busbar temperatures can accelerate the aging of insulation materials. Commonly used polyvinyl chloride (PVC) insulation materials, for example, lose elasticity and become brittle at high temperatures, resulting in decreased insulation performance. When the temperature exceeds the tolerance limit, the insulation layer may crack, leading to short circuits and other safety accidents. Furthermore, monitoring the copper busbar temperature can indirectly determine whether the busbar trunking is overloaded, as overload significantly increases the heat generated by the copper busbars, causing a rapid rise in temperature.
[0004] However, due to the large size of copper busbars, the temperature sensors currently cover a limited area and cannot comprehensively measure the temperature of the copper busbars. Forcibly increasing the number of temperature sensors not only increases costs, but also, since the temperature sensors are located inside dense busbar trunking, multiple temperature sensors undoubtedly increase the difficulty of power supply.
[0005] Therefore, in order to solve the above-mentioned technical problems, this application proposes an automatic temperature-measuring compact busbar trunking. Utility Model Content
[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an automatic temperature-measuring high-density busbar trunking.
[0007] To achieve the above objectives, this utility model provides the following technical solution: an automatic temperature-measuring high-density busbar trunking, comprising a busbar trunking body, a conductive busbar installed inside the busbar trunking body, and cover plates detachably connected to both laterally opposite sides of the busbar trunking body. The cover plates are groove-shaped, and the conductive busbars are supported by insulating support plates on both sides of the inner side of the cover plates. A reciprocating mechanism for driving a temperature sensor to move laterally is installed inside each cover plate, and the transmission part of the temperature sensor is in close contact with the surface of the conductive busbar. A transmission component is installed on the surface of the cover plate, which cooperates with the temperature sensor to transmit temperature information.
[0008] Preferably, the reciprocating mechanism includes a reciprocating lead screw driven by a motor located inside the cover plate, a through hole for the reciprocating lead screw to pass through on the insulating support plate, a rod sleeve threadedly connected to the outer wall of the reciprocating lead screw, the surface of the rod sleeve being connected to a temperature sensor, and a linear maintenance component for maintaining the linear movement of the rod sleeve back and forth is installed inside the cover plate.
[0009] Preferably, the linear support component includes guide rails fixed to the front and rear sides inside the cover plate, and sliders are slidably connected to the outer side walls of the guide rails. The rod sleeve is fixed between the two sliders, and the linear movement of the rod sleeve is maintained by the guide rails and sliders.
[0010] Preferably, an elastic component is installed between the rod sleeve and the temperature sensor, which helps the detection part of the temperature sensor to be more securely attached to the conductive busbar.
[0011] Preferably, the elastic component includes a hollow shell fixed to the surface of the sleeve, with sliding rods fixedly connected to both sides of the interior of the hollow shell for sliding of the sleeves, a connecting plate fixedly connected between the sleeves, a spring installed between the surface of the connecting plate and the inner surface of the hollow shell, the back of the connecting plate being fixed to a temperature sensor via a vertical rod, and a through groove for the vertical rod to pass through at the bottom of the hollow shell.
[0012] Preferably, the transmission component includes:
[0013] The microprocessor processes the temperature signal from the temperature sensor and sends a command to the LOAR wireless transmission module to send a signal to the outside world when the temperature reaches the critical point.
[0014] LOAR wireless transmission module: used to transmit alarm information processed by the microprocessor to the monitoring software backend for real-time display;
[0015] Power supply: Provides power to the electrical components on the transmission assembly.
[0016] Preferably, the insulating support plate has a connecting wire inside, and a plug for connecting the connecting wire is installed on its surface. The side of the temperature sensor has an interface that is compatible with the plug.
[0017] Compared with the prior art, the present invention has the following beneficial effects:
[0018] 1. This utility model uses a reciprocating mechanism to drive two temperature sensors to move laterally back and forth, thereby comprehensively detecting the temperature on the heat conduction busbar. When the temperature is abnormal, the temperature information is transmitted to the outside by the transmission component. In this way, the heat conduction busbar can be comprehensively detected by two temperature sensors, reducing the number of temperature sensors required. This solves the problem in the background technology that increasing the number of temperature sensors not only increases the cost, but also makes it more difficult to supply power due to the temperature sensors being located inside the dense busbar trunking.
[0019] 2. An elastic component is installed between the rod sleeve and the temperature sensor in this utility model. The elasticity of the elastic component helps the detection part of the temperature sensor to fit more firmly with the conductive busbar, which helps to improve the accuracy of the detection results.
[0020] 3. This utility model uses a reciprocating mechanism to move the temperature sensor to the outermost side, so that its interface can be inserted into the connector and electrically connected with the power cord, thereby powering the battery inside the temperature sensor, which is very convenient.

[0028] like Figure 1-5 As shown, this utility model provides an automatic temperature-measuring high-density busbar trunking, including a busbar trunking body 1. A conductive busbar 2 is installed inside the busbar trunking body 1. There are cover plates 3 on the two horizontally opposite sides of the upper and lower ends of the busbar trunking body 1 (the appropriate opposite sides of the cover plates 3 are selected according to actual needs, mainly based on the need for thickness detection of the conductive busbar 2, and are not fixed to the two sides shown in the figure). The cover plates 3 are groove-shaped, and the conductive busbar 2 is supported by insulating support plates 4 on both sides of the inside of the cover plates 3. A reciprocating mechanism 7 for driving the temperature sensor 6 to move laterally is installed inside the cover plates 3, and the transmission part of the temperature sensor 6 is in close contact with the surface of the conductive busbar 2. A transmission component 8 is installed on the surface of the cover plates 3, which cooperates with the temperature sensor 6 to transmit temperature information.
[0029] In use, two cover plates 3 are installed on the upper and lower sides of the main body 1 of the busbar trunking. After installation, the insulating support plate 4 on the cover plate 3 can support the conductive busbar 2, thereby maintaining its position (although the conductive busbar 2 has been fixed in the busbar trunking by screws, clamps or other fixing devices, if there is no auxiliary support from the insulating support plate 4, the heat conduction busbar will shift slightly due to gravity over time, causing the temperature sensor 6 to be unable to stick to the conductive busbar 2 to detect its temperature). At this time, the detection part of the temperature sensor 6 inside the cover plate 3 is in contact with the upper and lower surfaces of the busbar, and the reciprocating mechanism 7 drives the two temperature sensors 6 to move back and forth laterally to comprehensively detect the temperature on the heat conduction busbar. When the temperature is abnormal, the temperature information is transmitted to the outside by the transmission component 8. In this way, the conductive busbar 2 can be comprehensively detected by the two temperature sensors 6, reducing the number of temperature sensors 6 required.
[0030] The transmission component 8 includes a microprocessor, a LoAR wireless transmission module, and a power supply. Temperature sensor 6 first collects real-time temperature data from various parts of the busbar 2 and generates temperature signals. These signals are transmitted to the microprocessor. As the core unit for data processing, the microprocessor receives the signals from temperature sensor 6 and uses its built-in algorithms and logic to analyze and process the signals, continuously monitoring whether the temperature reaches a preset critical point. Once the temperature reaches this critical point, the microprocessor sends a specific trigger command to the LoAR wireless transmission module according to preset instructions, requesting it to send out a signal. Upon receiving the command from the microprocessor, the LoAR wireless transmission module uses its low-power wide-area network communication technology to encode and modulate the data containing alarm information processed by the microprocessor, and then sends it wirelessly to the monitoring software backend. The monitoring software backend receives the data, decodes and processes it, and finally displays the alarm information in real time so that relevant personnel can promptly be aware of abnormal temperatures and take appropriate measures. The power supply is provided by the microprocessor and LoAR wireless transmission module in the transmission component 8. The wireless transmission module and other power-consuming components provide stable power to ensure the normal operation of the entire system. Driven by the power supply, each component works in concert to realize the complete functional process from temperature monitoring to remote transmission and display of alarm information.
[0031] The following is the specific structure of the reciprocating mechanism 7: The reciprocating mechanism 7 includes a reciprocating lead screw 702 driven by a motor 701 located inside the cover plate 3. An insulating support plate 4 has a through hole 5 for the reciprocating lead screw 702 to pass through. A rod sleeve 703 is threadedly connected to the outer wall of the reciprocating lead screw 702. The surface of the rod sleeve 703 is connected to the temperature sensor 6. A linear maintenance component is installed inside the cover plate 3 to maintain the linear movement of the rod sleeve 703 back and forth. The other end of the reciprocating lead screw 702 connected to the motor 701 is rotatably connected to the inner surface of the cover plate 3 through a bearing, thereby providing rotational support for the reciprocating lead screw 702 through the bearing.
[0032] It should be noted that the motor 701 is located outside the cover plate 3 for easy power supply.
[0033] In use, the motor 701 drives the reciprocating screw 702 to rotate, the reciprocating screw 702 drives the rod sleeve 703 to move back and forth, the rod sleeve 703 drives the slider 705 to move back and forth, the slider 705 slides along the guide rail 704 to maintain the back and forth linear movement of the rod sleeve 703, and the rod sleeve 703 can drive the temperature sensor 6 to move back and forth in a horizontal linear motion.
[0034] Furthermore, this utility model also provides a power supply structure for the temperature sensor 6: an insulating support plate 4 has a connecting wire inside, and a plug 10 connected to the connecting wire is installed on its surface. The side end of the temperature sensor 6 is provided with an interface 11 that is compatible with the plug 10. That is, when the built-in battery of the temperature sensor 6 is depleted, the connecting wire inside the insulating support plate 4 can be energized, and the temperature sensor 6 can be moved to the outermost side by the reciprocating mechanism 7 (and then will not move until the charging is finished), so that the interface 11 on it can be inserted into the connector and form an electrical connection with the connecting wire, thereby powering the battery inside the temperature sensor 6, which is very convenient (because the temperature sensor 6 needs to be moved, it is difficult to directly power it through the line).
[0035] Furthermore, an elastic component 9 is installed between the sleeve 703 and the temperature sensor 6. The elasticity of the elastic component 9 helps the detection part of the temperature sensor 6 to fit more firmly against the conductive busbar 2, which helps to improve the accuracy of the detection results. The elastic component 9 includes a hollow shell 901 fixed to the surface of the sleeve 703. Sliding rods 902 for sliding sleeves 903 are fixedly connected to both sides inside the hollow shell 901. A connecting plate 904 is fixedly connected between the sliding sleeves 903. A spring 905 is installed between the surface of the connecting plate 904 and the inner surface of the hollow shell 901. The back of the connecting plate 904 is fixed to the temperature sensor by a vertical rod 906. A through groove 9 is opened at the bottom of the hollow shell 901 for the vertical rod 906 to pass through. 07. When the cover plate 3 is installed on the main body 1 of the busbar trunking, the temperature sensor 6 will come into contact with the heat conduction busbar, thereby driving the vertical rod 906 to move along the through groove 907 into the hollow shell 901. This causes the connecting plate 904 to move along the hollow shell 901. The connecting plate 904 drives the sliding sleeve 903 to move. The sliding sleeve 903 slides along the sliding rod 902 to maintain the linear movement of the connecting plate 904 (to prevent the spring 905 from being damaged by oblique pulling). At the same time, the spring 905 is compressed. The spring 905 uses its elasticity to always provide the temperature sensor 6 with a pressure in the direction of the heat conduction busbar through the connecting plate 904 and the vertical rod 906, so that the detection part of the temperature sensor 6 can be more firmly attached to the heat conduction busbar 2.
