Description

Technical Field

[0001] The utility model relates to the technical field of cable temperature detection, in particular to a portable cable temperature detector. Background Art

[0002] The power cable is in working state for a long time, and the voltage and current carried by the power cable are also increasing. Due to the high current and voltage, the cable temperature rises continuously during operation. When it reaches a certain limit, it will cause equipment short circuit, tripping and other problems, which may also cause safety hazards. It is necessary to pay attention to the temperature of the cable during operation.

[0003] Existing cable temperature detection devices usually install a temperature sensor in a long sealed shell customized according to the cable for detection. However, the sealed shell is difficult to fit on the cable, which makes installation inconvenient and difficult to implement. Once the cable has a high temperature problem and needs to be repaired, the sealed shell is difficult to disassemble, and it is difficult to continue using it after repair, resulting in poor use effect.

[0004] Currently, the temperature of cables is detected by thermochromic labels to avoid potential safety hazards caused by high temperatures. However, thermochromic labels are inconvenient to fix, which affects the detection efficiency.

[0005] Chinese patent 2022202095203 provides a portable cable temperature detector, including a transparent shell and a label strip. The shell is composed of two mutually hinged clamp shells. A reset elastic plate is connected between the two clamp shells and at the hinge. The reset elastic plate is made of elastic material. The ends of the two clamp shells are connected to inner extension plates. Tension springs are connected between the two inner extension plates and the two ends of the label strip. The opening of the shell is expanded and moved to the outside of the detection cable. The reset elastic plate automatically merges the shell. At the same time, the tension spring can cover the label strip on the outer wall of the cable. The copper label strip can transfer heat to the thermochromic label. Its color changes to determine whether the temperature is within a safe range. When in use, the opening of the shell is enlarged and moved to the outside of the detection cable. The reset elastic plate automatically merges the shell, and the tension spring can cover the label strip on the outer wall of the cable. The copper label strip can transfer heat to the thermochromic label to determine whether the temperature is within a safe range by its color change. Although Chinese Patent 2022202095203 has a simple structure, it is inconvenient to operate and requires both hands to measure. There are safety hazards when the measuring personnel operate within a close range of the cable. When the cable is at a higher position from the ground, it is more difficult for the operator to operate. Utility Model Content
