Method for measuring temperature of cable line and special thermodetector

Abstract

The invention discloses a method for measuring the temperature of a cable line and a special thermodetector. The special thermodetector comprises a measuring device and a display device, wherein the measuring device is embedded into a cable chute and used for measuring the cable temperature; and the display device is used for displaying temperature data. By the Method for measuring the temperature of the cable line and the special thermodetector, the temperature measurement for the cable line is carried out, the temperature measurement for the cable line of the environment inaccessible to various geographical environments and persons can be satisfied. The special thermodetector has the advantages of simple structure, small size, light weight and strong generality, and is convenient and flexible for operation. Because patrol inspectors do not need to excavate the cable chute, the environment and the transpiration are not influenced, the labor intensity is reduced; the safety of the staff is ensured; the operation time is greatly shortened; the safety degree is improved; and the production efficiency is enhanced.

Description

technical field [0001] The invention belongs to the technical field of cable line temperature measurement method and equipment, and in particular relates to a cable line temperature measurement method and a special thermometer. Background technique [0002] In order to ensure the normal operation of the cable line, it is necessary to inspect the running cable, and the temperature measurement of the cable line is an important inspection method. Power cables are generally buried in cable trenches and are often laid along streets. If conventional temperature measurement methods are used, cable trenches will need to be excavated, and the road surface will even be damaged. Therefore, the project volume is large, the construction is difficult, and it will affect the public environment and transportation. At the same time, the environment in the cable trench is dangerous. On the one hand, there is a lack of oxygen. On the other hand, if there are dead animals in the cable trench, p...

Problems solved by technology

Power cables are generally buried in cable trenches and are often laid along streets. If conventional temperature measurement methods are used, cable trenches need to be excavated, or even the road surface will be damaged. Therefore, the amount of engineering is large, the construction is difficult, and it will affect the public environment and transportation.

At the same time, the environment in the cable trench is dangerous. On the one hand, there is a lack of oxygen. On the other hand, if there are dead animals in the cable trench, poisonous and harmful gases will be produced if they exist for a long time. People entering the cable trench will be in danger of life.
