Abstract

This utility model discloses a real-time temperature monitoring device for busbar trunking based on distributed optical fiber sensing, relating to the field of busbar trunking. It includes: an internal frame; a temperature-sensing support assembly slidably installed within the internal frame; and a copper busbar mounted on the temperature-sensing support assembly, with both ends extending out of the internal frame. The temperature-sensing support assembly includes two sliding blocks, with a support block fixed between them.

Description

Technical Field

[0001] This utility model relates to the field of bus trunking, and in particular to a real-time temperature monitoring device for bus trunking based on distributed optical fiber sensing. Background Technology

[0002] Busbar trunking is an enclosed metal device used for power transmission, widely applied in high-rise buildings, data centers, factories, and other locations to distribute large amounts of power. During operation, busbar trunking generates heat, especially at connection points and busbar locations. If the temperature is too high, it may lead to insulation aging or even a fire.

[0003] Traditional methods for monitoring busbar temperature have several shortcomings. For example, contact temperature sensors are susceptible to electromagnetic interference and are complex to install; while non-contact infrared temperature measurement can avoid electromagnetic interference, it cannot achieve distributed measurement and has limited accuracy. In addition, busbars are usually installed in narrow spaces, making it difficult for manual inspection to cover all areas and impossible to monitor in real time.

[0004] Therefore, it is necessary to propose a real-time busbar temperature monitoring device based on distributed optical fiber sensing to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a real-time busbar trunking temperature monitoring device based on distributed optical fiber sensing, to address the many shortcomings of traditional busbar trunking temperature monitoring methods. For example, contact temperature sensors are susceptible to electromagnetic interference and are complex to install; while non-contact infrared temperature measurement can avoid electromagnetic interference, it cannot achieve distributed measurement and has limited accuracy. Furthermore, busbar trunking is typically installed in confined spaces, making it difficult for manual inspection to cover all areas and enabling real-time monitoring.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a busbar trunking temperature real-time monitoring device based on distributed optical fiber sensing, comprising:

[0007] Internal framework;

[0008] A temperature measuring support assembly, which is slidably installed within an internal frame;

[0009] A copper busbar, which is mounted on a temperature measuring support assembly and has both ends extending out of the internal frame;

[0010] The temperature measuring support assembly includes two sliding blocks, and a support block is fixed between the two sliding blocks. The support block has a support opening in the middle for the copper busbar to pass through.

[0011] The support block has heat dissipation holes at both the top and bottom, and the sliding block has heat dissipation grooves that communicate with the corresponding heat dissipation holes.

[0012] Preferably, the internal frame has mounting grooves at both the top and bottom, and a temperature measuring optical fiber is installed between the two ends inside the mounting groove.

[0013] The support opening and the heat dissipation hole are connected;

[0014] The sliding block is slidably installed between the two sides inside the mounting groove, and a through hole is provided on the sliding block for the temperature measuring optical fiber to slide through.

[0015] Preferably, the mounting groove has sliding grooves on both sides, and the two ends of the sliding block are slidably installed in the corresponding sliding grooves.

[0016] Preferably, an optical fiber interface is provided at the top of the internal frame.

[0017] Preferably, baffles are fixedly connected to the top and bottom of the internal frame, and heat dissipation fins are fixed to the two baffles on the side away from each other.

[0018] The fiber optic interface has a corresponding baffle protruding from its top.

[0019] Preferably, side plates are fixed on both sides of the internal frame.

[0020] The technical effects and advantages of this utility model are as follows:

[0021] 1. In the actual operation of this utility model, the two sliding blocks can move along the length of the inner frame, which facilitates the support of the copper busbar at different positions. The support block between the two sliding blocks can support the inner copper busbar, and the two sliding blocks can support the temperature measuring optical fiber in the mounting slot, so as to prevent the temperature measuring optical fiber from collapsing after long-term use.

[0022] 2. Furthermore, the heat generated by the copper busbars supported inside the support block during operation can be discharged to the top of the sliding block through the heat dissipation holes and then discharged from the heat dissipation groove. Since the top of the heat dissipation groove is equipped with a baffle with heat dissipation fins, it can absorb heat and exchange it with the outside air, further improving the heat dissipation performance and preventing heat from accumulating inside the support opening.

[0023] 3. Temperature-measuring optical fibers utilize the light scattering effect to measure temperature distribution, enabling continuous temperature monitoring along the fiber's length. Temperature monitoring of the entire copper busbar can be achieved through vertically distributed temperature-measuring optical fibers, making it more accurate and easier to install compared to temperature sensor monitoring.

[0028] This utility model provides, for example Figures 1-3 The bus trunking temperature real-time monitoring device based on distributed optical fiber sensing shown includes:

[0029] Internal frame 2, as the main structure of the entire device, is used to support and fix other components.

[0030] To address the shortcomings of traditional busbar temperature monitoring methods, such as the susceptibility of contact temperature sensors to electromagnetic interference and complex installation, and the limitation of non-contact infrared temperature measurement (which avoids electromagnetic interference but cannot achieve distributed measurement and has limited accuracy), and the fact that busbars are typically installed in confined spaces, making comprehensive manual inspection difficult and real-time monitoring impossible, a temperature measurement support assembly is proposed. This assembly is slidably installed within the internal frame 2.

[0031] Copper busbar 5 is installed on the temperature measuring support assembly, and both ends of copper busbar 5 extend out of the inner frame 2. The temperature measuring support assembly is used to support and fix copper busbar 5.

[0032] The temperature measuring support component includes a sliding block 9, and there are two sliding blocks 9. A support block 11 is fixed between the two sliding blocks 9. A support opening 14 for the copper busbar 5 to pass through is opened in the middle of the support block 11. The top and bottom of the internal frame 2 are both provided with mounting grooves 6. A temperature measuring optical fiber 7 is installed between the two ends inside the mounting groove 6.

[0033] The support block 11 has heat dissipation holes 12 at both the top and bottom. The sliding block 9 has heat dissipation grooves 10 that communicate with the corresponding heat dissipation holes 12. The support opening 14 communicates with the heat dissipation holes 12. The internal frame 2 has baffles 3 fixedly connected to both the top and bottom. The two baffles 3 are fixed with heat dissipation fins 4 on one side away from each other.

[0034] In the actual operation of this utility model, the two sliding blocks 9 can move along the length of the inner frame 2, which facilitates the support of the copper busbar 5 at different positions. The support block 11 between the two sliding blocks 9 can support the inner copper busbar 5, and the two sliding blocks 9 can support the temperature measuring optical fiber 7 in the mounting groove 6, so as to prevent the temperature measuring optical fiber 7 from collapsing after long-term use.

[0035] Furthermore, the heat generated by the copper busbar 5 supported inside the support block 11 during operation can be discharged to the top of the sliding block 9 through the heat dissipation hole 12 and discharged from the heat dissipation groove 10. Since the top of the heat dissipation groove 10 is provided with a baffle 3 with heat dissipation fins 4, it can absorb heat and exchange with the outside air, further improving the heat dissipation performance and preventing heat from accumulating inside the support opening 14.

[0036] The temperature-measuring fiber 7 utilizes the scattering effect of light (such as Brillouin scattering and Raman scattering) to measure temperature distribution, enabling continuous temperature monitoring along the length of the fiber.

[0037] The sliding block 9 is slidably installed between the two sides inside the mounting groove 6, and the sliding block 9 has a through hole for the temperature measuring optical fiber 7 to slide through.

[0038] The mounting slot 6 has sliding grooves 13 on both sides inside. The two ends of the sliding block 9 are slidably installed in the corresponding sliding grooves 13 to ensure the stable movement of the temperature measuring support component.

[0039] The top of the internal frame 2 is equipped with a fiber optic interface 8 for connecting to an external fiber optic sensing system to transmit temperature data to the monitoring center. The top of the fiber optic interface 8 has a corresponding baffle 3 protruding for easy connection.

[0040] Side plates 1 are fixed on both sides of the internal frame 2 to enhance the structural stability of the entire device.
