Reinforced temperature measurement optical cable

Abstract

The invention relates to a reinforced temperature measurement optical cable. The optical cable comprises bare optical fibers, an armored layer, a braid layer and a protective jacket. A plurality of bare optical fibers are arranged in the armored layer, the braid layer coats an outer layer of the armored layer, one or more protective jackets are arranged outside the braid layer, and a tight tube layer can be added outside each bare optical fiber to form a tight tube optical fiber. The reinforced temperature measurement optical cable is scientific and reasonable in design and simple in structure. To overcome defects in the prior art, an outermost layer of the optical cable does not use a sheath made of a non-metal material for protection any more, instead, a metal material is used as a protection and tensile element, the whole optical cable material has no non-metallic material except the optical fiber and the protective layer, the temperature conduction performance of the metal materialis much better than that of the non-metal material, therefore, the temperature conduction is rapid and timely, the rapid response to temperature measurement can be guaranteed, the temperature distribution of a whole line can be known timely, and at the same time, the reinforced temperature measurement optical cable has good lateral pressure resistance and tensile resistance and can be suitable for occasions with high requirements for lateral pressure resistance and tensile resistance.

Description

technical field [0001] The invention belongs to the field of optical cable processing, and relates to a temperature-measuring optical cable, in particular to a reinforced temperature-measuring optical cable. Background technique [0002] Optical fiber sensing technology is a new sensing technology along with the development of optical fiber and optical fiber communication technology. It is the fastest-growing high-tech application technology in the world since the mid-1970s. There are two main types of optical fiber sensing technology currently on the market, one uses optical fiber directly as a sensor, and the other uses a grating-based sensor. Fiber optic sensors (FOSFIBEROPTICAL SENSOR) are essentially different from electrical-based sensors. Optical fiber sensors use light as the carrier of sensitive information and optical fiber as the medium for transmitting sensitive information, and are widely used due to their unique characteristics. [0003] The direct use of op...

Problems solved by technology

[0003] The direct use of optical fiber as a sensor needs to be based on the temperature measurement optical cable. The existing temperature measurement optical cable technology generally has a layer of non-metallic sheath as a protection on the outermost layer, and the thermal conductivity of general non-metallic materials is poor, which is not conducive to the rapid conduction of temperature. , leading to a long lag in the timeliness of the temperature, the applicability is not good in occasions that require rapid temperature measurement, and it is not conducive to the rapid perception of temperature
