Power cable temperature measuring device and operating method thereof

Abstract

The invention relates to the technical field of temperature measuring devices and discloses a power cable temperature measuring device and an operating method thereof. The power cable temperature measuring device comprises an upper open box, and the bottom of the upper open box is movably connected with a lower open box. Cable lines are movably connected between the upper open box and the lower open box in a sleeved mode. The obverse sides of the upper open box and the lower open box are fixedly connected with semi-bearing pipes correspondingly. The two semi-bearing pipes are movably connected, and the bottoms of the semi-bearing pipes fixedly communicate with a water discharging hopper. An air outlet pipe is fixedly connected to the right side of the upper open box in a sleeving mode, andone end of the air outlet pipe extends into the upper open box. According to the power cable temperature measuring device and the operating method thereof, under the effect of three clamping pieces,the cable lines with different thicknesses can be clamped, through matching of a movable rod and a threaded bolt, the cable lines are fixed, then the effect that the cable lines with the different thicknesses are clamped and fixed is achieved, and thus practicability of the whole device is improved.

Description

technical field [0001] The invention relates to the technical field of temperature measuring devices, in particular to a power cable temperature measuring device and an operating method thereof. Background technique [0002] Power cables are cables used to transmit and distribute electric energy. Power cables are often used in urban underground power grids, outgoing lines of power stations, internal power supply of industrial and mining enterprises, and underwater transmission lines across rivers and seas. In power lines, the proportion of cables is gradually increasing. Power cables are cable products used to transmit and distribute high-power electric energy in the main line of the power system, including 1-500KV and above various voltage levels and various insulated power cables. In order to ensure the safe and reliable operation of the power grid and prevent various faults caused by excessive cable temperature, it is very important to measure the actual operating temper...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a power cable temperature measuring device and its operation method, which has the advantages of being able to be installed on cables of different thicknesses, free from external environment interference, and accurate temperature measurement, etc., which solves the existing problems. The power cable temperature measuring device cannot fix and clamp the temperature of cables with different thicknesses, resulting in limitations in the use of the temperature measuring device. There is also a long-term wind and sun exposure that causes internal damage to the temperature measuring device and external The temperature affects the accuracy of the temperature measurement device on the temperature measurement
