Abstract

A novel temperature measuring cable sequentially comprises a core layer, a cladding, a coating, a buffering layer, a metal armor cladding, a reinforcing layer and an outer protective layer from inside to outside. The core layer is of a solid structure, the outer wall of the core layer is wrapped by the cladding, the outer wall of the cladding is wrapped by the coating, the outer wall of the coating is wrapped by the buffering layer, the outer wall of the buffering layer is wrapped by the metal armor cladding, the outer wall of the metal armor cladding is wrapped by the reinforcing layer, and the outer wall of the reinforcing layer is wrapped by the outer protective layer. The core layer and the cladding are made of a homogeneous material doped with silica glass or pure silica glass. The refractive index of the core layer is larger than that of the cladding. The buffering layer is filled with an aramid fiber in a knitting mode. According to the novel temperature measuring cable, high-precision, quick-response and high-strength optical fiber temperature measurement can be achieved, and the novel temperature measuring cable is simple in structure and long in service life.

Description

technical field [0001] The invention relates to the field of optical fiber temperature measurement, in particular to a novel temperature measurement optical cable, which is specifically suitable for providing a high-precision, high-response, and high-strength temperature-measurement optical cable under environmental conditions such as cable tunnels, cable trenches, and oil pipelines. Background technique [0002] At present, in the field of distributed temperature measurement, optical fiber temperature measurement technology has gradually replaced the traditional temperature measurement technology, and has become the preferred technology in the application field of temperature measurement in cable tunnels and oil pipelines. In the application of optical fiber temperature measurement, it has become an important direction for the development of optical fiber temperature measurement technology to improve the accuracy and time response of temperature measurement, and to design te...
