Temperature rise causes relatively high temperatures of the basic components that constitute electrical contact: high temperature accelerates oxidation of the contact interface, increasing resistance, which leads to further heating and, as a result, higher temperatures. If the materials constituting wire clamps, wires, and contacts are not properly or adequately protected, wire clamps, wires, and contacts may be irreparably damaged before the expected service life of the equipment. In addition, temperature rise also affects the terminal and the connected wire. In order to ensure that the insulation of the wire remains intact during the life of the equipment, the impact of temperature rise should be limited.

Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters represent similar items in the following drawings, and therefore, once a certain item is defined in an accompanying drawing, it does not need to be further discussed in subsequent drawings.

[0029] like Figure 1 and Figure 2 As shown, in this embodiment, the cable temperature detection device includes: a test body 10, a buckle part 20, an energy extraction circuit 30, an alarm device 40 and a temperature sensor 50, the buckle part 20 includes a first arm 21 and a second arm 22, the first end of the first arm 21 is hingedly connected to the test body 10, the first end of the second arm 22 is hingedly connected to the test body 10, the second end of the first arm 21 and the second end of the second arm 22 can be opened and closed, the buckle part 20 has a locking position and an unlocking position, when the buckle part 20 is in the locking position, the second end of the first arm 21 and the second end of the second arm 22 are connected, and a threading space is formed between the test body 10, the first arm 21 and the second arm 22, when the buckle part 20 is in the unlocking position, the second end of the first arm 21 and the second end of the second arm 22 are separated. The energy extraction circuit 30 is arranged in the test body 10 and the buckle part 20. The alarm device 40 is arranged on the test body 10. The temperature sensor 50 is disposed on the test body 10 and is electrically connected to the alarm device 40 and the energy extraction circuit 30 .

[0030] By applying the technical solution of this embodiment, the first end of the first clamp arm 21 is hingedly connected to the test body 10, the first end of the second clamp arm 22 is hingedly connected to the test body 10, the second end of the first clamp arm 21 and the second end of the second clamp arm 22 can be opened and closed, and a threading space is formed between the test body 10, the first clamp arm 21 and the second clamp arm 22. The energy extraction circuit 30 is arranged in the test body 10 and the buckle part 20. The alarm device 40 is arranged on the test body 10. The temperature sensor 50 is arranged on the test body 10 and is electrically connected to the alarm device 40 and the energy extraction circuit 30. Through the above-mentioned arrangement, the arrangement of the buckle part 20 enables the device to be easily installed and removed on various cables without direct contact with the cables, thereby ensuring the safety of the operator. The arrangement of the energy extraction circuit 30 can obtain energy from the electromagnetic field around the cable to power the temperature sensor 50 and the alarm device 40 without the need for an external power supply, which greatly improves the portability and practicality of the device. The temperature sensor 50 can detect the temperature of the cable in real time and remind the operator through the alarm device 40, thereby achieving good detection accuracy. Therefore, the technical solution of this embodiment effectively solves the problem of the difficulty in transporting the temperature measuring device in the related art.

[0031] Specifically, this design enables the cable temperature detection device to flexibly adapt to cables of different diameters, making it easy to install and disassemble, and is particularly suitable for temperature monitoring of high-voltage cables in power systems. In practical applications, this device can quickly adapt to changes in the diameters of various cables, and can be installed and disassembled without additional tools, greatly improving the efficiency and flexibility of power system maintenance. Especially in high-voltage environments, this design, which does not require direct contact with the cable, greatly ensures the safety of operators and reduces the risk of accidents.

[0032] like Figure 2 and Figure 3 As shown, in this embodiment, the energy harvesting circuit 30 includes an energy harvesting coil 31 and a current conversion structure 32. The energy harvesting coil 31 can harvest energy from the electromagnetic field around the cable, and the current conversion structure 32 converts the harvested energy into electrical energy suitable for use by the temperature sensor 50 and the alarm device 40, without the need for an external power supply, and is suitable for use in the wild or in an environment where wiring is difficult.

[0033] By utilizing the electromagnetic field around the cable to obtain energy, this not only reduces dependence on batteries or other external power sources, reduces maintenance costs and the frequency of power supply replacement, but also greatly broadens the scope of application and improves practicality in field environments without power supply or in power facilities where wiring is difficult.

[0034] like Figure 1 and Figure 2As shown, in this embodiment, the alarm device 40 is a triangular block 41, and the cross-sectional area of ​​the triangular block 41 gradually increases from the top of the test body 10 to the bottom of the test body 10, and the triangular block 41 is rotatably arranged. When the cable temperature is abnormal, the triangular block 41 rotates, and its shape change can intuitively display the temperature state, which is convenient for the staff to observe from a distance.

[0035] Specifically, the design of the triangular block 41 can not only intuitively display the temperature change, but its gradually increasing cross-sectional area can also produce a significant visual effect when the temperature is abnormal, making long-distance observation easier.

[0036] like Figure 1 and Figure 2 As shown, in this embodiment, a avoidance space 11 is provided on the test body 10, and the triangular block 41 is rotatably disposed in the avoidance space 11. The design of the avoidance space 11 not only protects the alarm device 40, but also reduces obstacles to the device during installation and disassembly, improves work efficiency, and is suitable for cable temperature monitoring in various complex environments. The design of the avoidance space 11 not only protects the alarm device 40, but also ensures that the installation and disassembly process of the device in various complex environments is smoother, reduces operation time, and improves work efficiency. Especially in an environment with a small space or many obstacles, the design of the avoidance space 11 can avoid collision with the surrounding environment and ensure the normal installation and use of the device.

[0037] like Figure 1 and Figure 2 As shown, in this embodiment, the cable temperature detection device further includes a first magnetic structure 60, the first magnetic structure 60 includes a first magnetic member 61 and a magnetic member 62, one side of the first magnetic member 61 and the magnetic member 62 is arranged at the second end of the first clamping arm 21, and the other side of the first magnetic member 61 and the magnetic member 62 is arranged at the second end of the second clamping arm 22. The addition of the first magnetic structure 60 not only enhances the locking effect of the buckle portion 20, but also simplifies the operation process and improves the work efficiency, and is particularly suitable for occasions that require frequent installation and disassembly, such as maintenance and overhaul of power facilities.

[0038] The use of the first magnetic structure 60 not only enhances the connection stability between the device and the cable, but also simplifies the operation process, so that during the daily maintenance and inspection of the power facilities, the installation and disassembly of the device can be completed quickly, thereby improving work efficiency and reducing the labor intensity of operators.

[0039] Specifically, in this embodiment, the cable temperature detection device also includes a temperature monitoring circuit module, a detachable signal generator, a signal collector, and a monitoring terminal. The information of the signal collector or the monitoring terminal can be used by the on-site relay protection, monitoring system, etc. through standard protocols. For power distribution equipment that does not require real-time monitoring and has poor on-site communication signals, the operation and maintenance personnel can choose not to use the signal collector according to actual operation requirements, and only realize on-site temperature monitoring and alarm.

[0040] The device obtains energy directly from the cable through the energy taking coil 31, and provides electrical energy to the temperature sensor 50, the temperature monitoring circuit module, the alarm device 40, and the detachable signal generator for normal operation. The device monitors the temperature of the power distribution equipment through the temperature sensor 50, and outputs the collected real-time temperature data to the temperature monitoring circuit. The temperature monitoring circuit processes the data. If the temperature reaches the alarm value, the alarm device 40 is activated, and the alarm device 40 "flips" to form a striking warning sign to achieve the purpose of on-site warning. If the temperature is monitored to return to the normal value, the alarm device 40 "flips" and returns to normal, and then sends a warning signal when the temperature exceeds the upper limit. If the device needs to monitor data in real time, a signal generator is installed in the device. After the temperature monitoring circuit processes the data, the data is output to the signal generator at a preset time interval. After receiving the data, the signal generator transmits the data to the signal collector. The signal collector can transmit data in two ways: the first way is to transmit the data to the monitoring terminal through wireless communication or optical fiber communication; the second way is to transmit the data to the on-site distribution network automation terminal equipment, and then transmit it to the upper-level monitoring system through the encrypted communication module of the automation equipment, so as to save resources and ensure the security of data transmission.

This design enables the operating device to remotely control the opening and closing of the cable temperature detection device, avoids the risk of direct contact with high-voltage cables, ensures the safety of operation, and is suitable for remote monitoring and maintenance of power facilities.

[0043] Through the design of the operating lever 71 and the clamping part 72, the operator can safely and conveniently control the opening and closing of the cable temperature detection device at a long distance, at a high place or in a dangerous environment, avoiding the danger of direct contact with the high-voltage cable, greatly improving the safety and flexibility of the operation, and is particularly suitable for large-scale remote monitoring and maintenance of power facilities.

The use of the second magnetic attraction structure 80 not only enhances the connection stability between the operating device and the cable temperature detection device, but also simplifies the operation process and improves the work efficiency, and is particularly suitable for cable temperature detection in harsh environments. In harsh weather conditions or complex working environments, such as strong winds, rain and snow weather or saturated steam and dust environments, the second magnetic attraction structure 80 can ensure a stable and reliable connection between the operating device and the cable temperature detection device, avoid unstable connection or operation failure caused by environmental factors, improve work efficiency, and ensure the accuracy of detection data.

This transmission structure 90 design enables the operating device to accurately control the opening and closing of the cable temperature detection device, improves the accuracy and efficiency of the operation, and is particularly suitable for occasions requiring precise operation, such as cable temperature detection of precision equipment. Through the precise transmission structure 90, the operating device can realize precise control of the cable temperature detection device, which is suitable for occasions with high requirements for operation accuracy, ensures the accuracy and stability of the detection, and improves the efficiency and quality of the overall operation.

[0048] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the devices or elements referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention.

[0049] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0050] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the present invention.
