Description

Technical Field

[0001] The utility model relates to the field of cable temperature measurement and monitoring devices, in particular to an underground cable temperature measurement and monitoring device. Background Technique

[0002] With the continuous acceleration of China's urbanization process and the continuous improvement of people's living standards, the electricity consumption is increasing continuously, and the construction of power supply lines is imperative. Due to the constraints of urban resources and environment, overhead transmission lines increasingly do not meet the development needs of cities. A large number of overhead transmission lines have begun to be transferred underground. This method has been adopted in many cities around the world and has obtained good economic benefits, and the development speed is also getting faster and faster;

[0003] Chinese Patent with the publication number CN206740260U discloses an underground cable temperature measurement device, which includes a temperature measurement device body. A temperature sensor is arranged inside the temperature measurement device body, and a connection port is arranged on the side of the temperature measurement device body. It is fixed to the cable through a connection band passing through the connection port. The cable temperature measurement device is an active RFID. The environment of underground cables is extremely harsh, humid and high temperature, and there is no power supply. Traditional communication cannot work reliably in such an environment. It solves the problem of an electronic device that can work in an environment such as a cable trench or a cable well for a long time and work stably and reliably without maintenance; it can measure the temperature of the cable and the cable joint in real time for 24 hours, so as to monitor the working state of the cable and eliminate the need for maintenance personnel to measure on site; the utility model comes with a battery, and due to the ultra-low power consumption design, it can be continuously used for more than 5 years, saving daily maintenance work.

[0004] The above-mentioned underground cable temperature measurement and monitoring device of the patent is handheld and can generally only be used to measure the temperature of cables in underground pipes with a relatively large space that allows people to pass through, but it cannot measure the temperature of cables buried in a relatively narrow underground space.
