Online infrared temperature measuring device for electrical equipment joint

Abstract

The invention discloses an electrical equipment joint on-line infrared temperature measuring device which comprises an isolation shell used for protecting a cable connector and a limiting assembly arranged on the inner wall of the isolation shell, the limiting assembly comprises a lining, a limiting block, a storage rope, a rack and a driving assembly, the lining is embedded in the inner wall of the isolation shell in a sliding mode, and the limiting block is arranged on the inner wall of the isolation shell. According to the cable connector, the lining can be tightened through the limiting assembly, it is guaranteed that a cable of the cable connector has a limiting function, and it is avoided that the lining slips, an infrared temperature detector is dislocated, and the temperature measuring precision is reduced; the cable connector and the lining can be sealed, the situation that in the using process, the cable connector is corroded by water vapor, the cable connector is rusted, and the heat dissipation effect is reduced is avoided, and stable tightening and loosening of the stable storage rope can be achieved through the driving assembly.

Description

technical field [0001] The invention belongs to the technical field of temperature measurement, in particular to an on-line infrared temperature measurement device for electrical equipment joints. Background technique [0002] The cable joint is also called the cable head. After the cable is laid, in order to make it a continuous line, each segment of the line must be connected as a whole. These connection points are called cable joints. The cable joint in the middle of the cable line is called the intermediate joint. , and the cable joints at both ends of the line are called terminal heads. The cable joints are used to lock and fix the incoming and outgoing lines, and play the role of waterproof, dustproof and anti-vibration. [0003] Temperature measurement is a quantitative measurement of the temperature of an object with a temperature measuring instrument. The measurement of a physical quantity of temperature is actually a certain quantity of the object. The physical qua...

Problems solved by technology

[0004] Cables are mainly divided into power supply cables and signal cables. No matter what kind of cables are installed on the equipment, they are often protected by auxiliary tank chains to prevent scratches and damage, and important cables must be installed with additional temperature detection devices. Existing temperature detection equipment, whether it is a thermocouple or an infrared ray, needs to be attached to the cable connector. In the actual application process, simply adopt the snap-in method, which will cause slippage and misalignment problems on the frequently moving cables. , leading to a decrease in the accuracy of temperature detection, and it is more troublesome to disassemble, and it is not conducive to the sealing of the cable connector
