Abstract

The invention discloses a cable joint temperature data acquisition method, a monitoring device and a storage medium. The method comprises the following steps: S1, acquiring the current temperature ofa cable joint at an initial temperature sampling frequency; S2, comparing the current temperature with a preset cable joint temperature threshold, and changing a temperature sampling frequency according to a comparison result; S3, obtaining the temperature of the cable joint at the changed temperature sampling frequency, and repeating the steps S2 to S3. A cable joint temperature threshold value is preset, the acquired current temperature of the cable joint is compared with the preset cable joint temperature threshold, and the temperature sampling frequency is changed according to the comparison result, so that the intelligent dynamic adjustment of the cable joint temperature acquisition frequency is realized, the system resources can be reasonably utilized, and the service life of the cable joint temperature monitoring device is prolonged; and meanwhile, the operation temperature of the cable joint can be mastered in real time, potential safety hazards can be found in time, the line fault probability is reduced, and the line operation and maintenance cost is reduced.

Description

technical field [0001] The invention relates to the technical field of state monitoring of power transmission and distribution lines, in particular to a cable joint temperature data collection method, a monitoring device and a storage medium. Background technique [0002] As one of the key equipment for energy transmission in the power system, the cable's operating temperature is an important parameter reflecting the operating state of the system, and the cable joint, as the weakest link in the system, is the hardest hit area for line faults. The main reason is that as the running time of the line increases, the cable joints are more likely to heat up, thereby accelerating the oxidation of the cable, causing the contact resistance to increase and the temperature to rise, eventually forming a vicious circle and causing transmission line failure. Therefore, grasping the operating temperature of cable joints in real time can detect potential hidden dangers early, reduce the pro...
