Description

Technical Field

[0001] This utility model relates to the field of cable monitoring technology, specifically to a CT power measurement integrated device. Background Technology

[0002] Currently, temperature measurement products on the market are divided into two main categories: contact temperature measurement and non-contact temperature measurement. Non-contact temperature measurement products mainly include handheld infrared temperature measurement devices and cable-operated infrared temperature measurement devices. Handheld infrared temperature measurement devices directly display the measured temperature data on their own screen; however, they are relatively bulky and cannot achieve long-term real-time temperature monitoring of the product. Cable-operated infrared temperature measurement products, on the other hand, separate the infrared temperature measurement probe from the main unit, connecting the two via a data cable, enabling long-term online monitoring of the product's real-time temperature. Therefore, cable-operated infrared temperature measurement products are widely used in electrical, petroleum, chemical, and steel manufacturing and related equipment fields. However, in practical applications, for some equipment requiring real-time online temperature measurement, certain environments prohibit the use of external data cables, especially for high-voltage electrical equipment, whose installation locations are often complex and variable. Furthermore, current contact temperature measurement products are difficult to install in confined spaces, and their installation location can affect their ability to accurately align with the surface of the object being measured, easily leading to inaccurate measurement data. Environmental factors such as temperature, humidity, and dust can also affect the accuracy of the measurement data. Moreover, the power required by temperature measuring products is usually provided by batteries or power lines, but in confined spaces, battery replacement is inconvenient and power line laying is also difficult.

[0003] Therefore, the present invention provides a comprehensive CT power measurement device to solve the above problems. Utility Model Content

[0025] This disclosure aims to address the problem that existing temperature measurement products typically rely on batteries or power lines for power, which presents challenges in confined spaces, such as inconvenient battery replacement and difficult power line installation. Therefore, this disclosure proposes a comprehensive CT power supply measurement device. Through a cleverly designed fixing mechanism, it achieves stable fixation of cables of different sizes, enhancing the device's versatility and applicability. Its locking mechanism employs a dual locking mechanism of magnetic attraction and mechanical limiting, ensuring not only a quick and stable connection between the fixing shell and the CT power supply component but also improving the device's reliability and stability under complex operating conditions. The measurement component integrates temperature and humidity sensors, enabling real-time monitoring and display of temperature and humidity data near the cable, providing crucial information for the safe operation of electrical equipment. Furthermore, its quick disassembly and installation design significantly reduces maintenance and replacement time, lowers equipment downtime costs, and enhances the overall practicality and ease of operation of the device.

[0026] like Figures 1 to 7As shown, a CT power supply measurement integrated device includes a fixing device 1, a CT power supply component 2, and a measuring component 3. The fixing device 1 is fixed to the high-voltage cable of the distribution box and is used to fix the measurement integrated device to cables of different sizes. The CT power supply component 2 is installed on the fixing device 1, and the measuring component 3 is installed above the CT power supply component 2. The measuring component 3 is used to measure the temperature and humidity inside the distribution box.

[0027] By setting up a winding mechanism 3 and a detection mechanism 4, the automation and integration of fabric defect detection and winding are achieved. The detachable fixing frame 38 of the winding mechanism 3 facilitates fabric replacement and installation, improving operational convenience; the cooperation between the limiting block 5 and the limiting groove 3586 enhances the connection stability between the rotating shaft 35537 and the rotating drum 39, ensuring smooth operation during the winding process. In the detection mechanism 4, the visual inspection device 43 can efficiently and accurately detect fabric defects, while the automated marking function of the marking component 44 provides clear guidance for subsequent repair, improving the efficiency and accuracy of detection and repair.

[0028] like Figures 1 to 5 As shown, the fixing device 1 includes a fixing block 11, a locking band 12, a locking hole 13, a fixing band 14, and a locking block 15. The fixing block 11 is installed below the CT power supply assembly 2 and is used to install the CT power supply assembly 2. A locking band 12 is installed on one side of the fixing block 11, and the locking band 12 is used to cooperate with the locking hole 13 to achieve initial locking of the fixing band 14. The locking band 12 has a locking hole 13 for locking the locking block 15. A fixing band 14 is installed on the other side of the fixing block 11 and is used to cooperate with the locking block 15 to complete the fixing. Locking blocks 15 are arranged in an array on the fixing band 14 and are used to cooperate with the locking hole 13 to complete the locking. The locking block 15 is made of deformable rubber and the diameter of the locking block 15 is larger than the inner diameter of the locking hole 13.

[0029] During operation, the staff wraps the fixing strap 14 around the cable to be measured, and then inserts the locking block 15 into the locking hole 13. Since the length of the locking block 15 is greater than the longest inner diameter of the locking hole, the staff needs to apply external force to squeeze and deform the locking block 15 and the locking hole 13 so that the fixing strap 14 can be inserted into the locking hole 13. This achieves the fixing of the CT power supply component 2 and the measuring component 3 to the cable to be monitored by the fixing device 1.

[0030] Through the structural design of the fixing device 1, a stable fixing mechanism for cables of different sizes is achieved. The fixing device 1 employs a combination structure of fixing block 11, locking strap 12, locking hole 13, fixing strap 14, and locking block 15, which can flexibly adapt to cables of different diameters, enhancing the device's versatility and applicability. The locking block 15 is made of deformable rubber and its diameter is larger than the inner diameter of the locking hole 13. This design allows the locking block 15 to deform and insert into the locking hole 13 by external force during the fixing process, thereby achieving a tight connection between the fixing strap 14 and the locking strap 12. This ensures that the device will not loosen due to cable vibration or external force during operation, improving the reliability of the fixing. Furthermore, this fixing method is simple to operate; only external force needs to be applied by the operator to complete the fixing, without complicated tools or cumbersome steps, greatly improving installation efficiency and reducing installation costs. Simultaneously, the design of the fixing device 1 also provides a stable installation foundation for the CT power supply component 2 and the measurement component 3, ensuring the accuracy and stability of the measurement data.

[0031] like Figure 3 As shown, an auxiliary fixing rod 16 is provided at the end of the fixing band 14. The auxiliary fixing rod 16 is used to assist in fixing after the fixing band 14 is fixed. A limit ball 17 is installed on the auxiliary fixing rod 16. The limit ball 17 is used to be inserted into the limit hole 18 for further limiting. The locking band 12 is provided with a limit hole 18 for limiting the limit ball 17. The limit hole 18 is used to cooperate with the limit ball 17 to achieve limiting.

[0032] During operation, after the fixing strap 14 passes through the locking hole 13, the worker flips the fixing strap 14 behind the locking hole 13 in the opposite direction. The flipped fixing strap 14 drives the auxiliary fixing rod 16 to insert the limiting ball 17 into the limiting hole 18, which further locks the fixing strap 14 and the locking strap 12.

[0033] By providing an auxiliary fixing rod 16 and a limiting ball 17 on the fixing band 14, and a limiting hole 18 on the locking band 12, the stability and reliability of the fixing device 1 are further enhanced. In actual operation, after the fixing band 14 passes through the locking hole 13 and completes the initial fixing, the operator reverses the fixing band 14 and inserts the limiting ball 17 on the auxiliary fixing rod 16 into the limiting hole 18, thereby achieving a secondary locking of the fixing band 14 and the locking band 12. This double locking mechanism not only further prevents the fixing band 14 from loosening or shifting during operation, but also significantly improves the stability of the device under complex working conditions, especially when facing vibration, impact, or material fatigue caused by long-term use, effectively preventing the device from loosening.

[0034] like Figure 7As shown, the measuring component 3 includes a fixed housing 31, a temperature measuring sensor 32, a humidity measuring sensor 33, a display screen 34, and a locking mechanism 35. The fixed housing 31 is installed outside the CT power supply component 2 and is used to fix the measuring component 3. The temperature measuring sensor 32 and the humidity measuring sensor 33 are installed outside the fixed housing 31. The temperature sensor is used to measure the temperature near the cable, and the humidity measuring sensor 33 is used to measure the humidity near the cable. The display screen 34 is installed inside the fixed housing 31 and is used to display temperature and humidity measurement information. A locking mechanism 35 for quick disassembly and installation is installed between the fixed housing 31 and the CT power supply component 2.

[0035] During operation, the fixing shell 31 is installed above the CT power supply assembly 2 by the locking mechanism 35, and the real-time temperature and humidity data are measured by the temperature sensor and humidity sensor and displayed on the display screen 34.

[0036] The measuring component 3 integrates a temperature sensor 32 and a humidity sensor 33, used to measure the temperature and humidity near the cable, respectively. This integrated design allows for the simultaneous acquisition of two key environmental parameters, providing comprehensive data support for the operational status assessment of power equipment. Secondly, the measuring component 3 is mounted externally to the CT power-taking component 2 via a mounting housing 31. This split design not only facilitates installation and maintenance but also improves the versatility and interchangeability of the measuring component 3. Furthermore, the display screen 34 is installed inside the mounting housing 31, providing a clear view of real-time temperature and humidity data, facilitating on-site monitoring and improving operational convenience and efficiency. Simultaneously, the mounting housing 31 and the CT power-taking component 2 are connected via a locking mechanism 35, enabling quick disassembly and installation.

[0037] like Figure 3 , Figure 4 , Figure 6 and Figure 7As shown, the locking mechanism 35 includes a locking groove 351, a first magnetic pluck 352, a second magnetic pluck 353, an adjusting groove 354, a rotating shaft 355, a toggle piece 356, a limiting piece 357, and a limiting groove 358. The locking groove 351 is formed within the CT power supply assembly 2 and is used to lock the fixed housing 31. The first magnetic pluck 352 is installed in the locking groove 351, and the second magnetic pluck 353 is installed below the fixed housing 31. The first magnetic pluck 352 and the second magnetic pluck 353 cooperate to fix the fixed housing 31. The adjusting groove 354... A groove 354 is formed on the side wall of the locking groove 351, and the adjusting groove 354 is used to install the rotating shaft 355. The rotating shaft 355 is installed in the adjusting groove 354 and is used to rotate in conjunction with the rotation of the actuating piece 356. The actuating piece 356 is fixedly installed coaxially on the outside of the rotating shaft 355. The actuating piece 356 is used to rotate and drive the limiting piece 357 to rotate. The limiting piece 357 is installed on the actuating piece 356, and a limiting groove 358 corresponding to the fixing piece is installed on the outside of the fixing shell 31. The limiting groove 358 is used to place the limiting piece 357 to achieve the fixing of the fixing shell 31.

[0038] During operation, when the fixed shell 31 is placed into the locking groove 351, the design of the first magnetic suction piece 352 and the second magnetic suction piece 353 fixes the fixed shell 31 in the locking groove 351. At this time, the operator rotates the actuating piece 356 to make the limiting piece 357 rotate. The rotating limiting piece 357 is inserted into the limiting groove 358 to limit the fixed shell 31.

[0039] The combination of locking slot 351 and magnetic plate utilizes magnetic force to initially fix housing 31. This magnetic fixing method is not only simple and quick to operate, but also enables the initial positioning of housing 31 and CT power supply component 2 in a short time, improving installation efficiency. Secondly, the mechanical linkage structure of actuating plate 356, rotating shaft 355, and limiting plate 357 further enhances the stability of housing 31. When housing 31 is placed in locking slot 351, rotating actuating plate 356 causes limiting plate 357 to engage with limiting slot 358. This mechanical limiting method not only ensures the stability of housing 31 during operation but also prevents loosening due to external vibration or impact. Furthermore, the design of the locking mechanism 35 allows for quick disassembly and installation; simply reversing the actuating plate 356 releases housing 31, significantly reducing the time required for maintenance and replacement of measuring component 3.

[0040] The overall working process is as follows: The operator wraps the fixing strap 14 around the cable to be measured, and then inserts the locking block 15 into the locking hole 13. Since the length of the locking block 15 is greater than the longest inner diameter of the locking hole, the operator needs to apply external force to squeeze and deform the locking block 15 and the locking hole 13 so that the fixing strap 14 can be inserted into the locking hole 13. This achieves the fixing of the CT power supply component 2 and the measuring component 3 onto the cable to be monitored by the fixing device 1. At the same time, the fixing shell 31 is installed above the CT power supply component 2 by the locking mechanism 35. The real-time temperature and humidity data are measured by the temperature sensor and humidity sensor and displayed on the display screen 34.
