Abstract

The invention relates to a carbon fiber reinforced aluminum alloy composite house-service photoelectric cable with a temperature automatic measurement function. The cable is sequentially provided with an outer protection layer, a metal belt layer and an oxygen insulation layer from the exterior to the interior, wherein the oxygen insulation layer is internally provided with an optical unit and a plurality of core bodies, the core bodies are provided with insulation layers and aluminum alloy conductors, and the aluminum alloy conductors are arranged in the insulation layers; fillers are arranged among the optical unit, the core bodies and the oxygen insulation layer; each filler is provided with a carbon fiber reinforced core; the optical unit comprises a plurality of optical fibers, and at least one optical fiber is a grating optical fiber carved with a temperature-measurement grating. The carbon fiber reinforced aluminum alloy composite house-service photoelectric cable with the temperature automatic measurement function has the beneficial effects of completely meeting the requirements of modern intelligent buildings on the electrical performance, communication capabilities, mechanical properties, flame retardant properties, fire safety performance and long service lives of house-services cables, and meanwhile being capable of replacing with copper cables and saving the resource; by utilizing the carbon fiber reinforced cores, the tensile strength of the cable is greatly improved; the cable provided by the invention not only can communicate, but also can monitor the self temperature in real time.

Description

technical field [0001] The invention belongs to the field of cables, in particular to a carbon fiber-reinforced aluminum alloy home-entry photoelectric composite self-temperature-measuring cable. Background technique [0002] As the future power grid, the smart grid is an emerging industry that is safe, reliable, cost-effective, and green. With the rapid development of smart grid construction, the cables used in smart grids can transmit signals while transmitting electric energy. Not only electrical performance and safety performance, but also factors such as environmental protection, energy saving, and economy must be considered. Composite cables with optical fibers will become the development direction of construction cables. [0003] In addition, the tensile strength of the existing wires is not enough, and the resistance to natural disasters such as freezing rain and snow is low; the existing photoelectric composite cable has the function of optical fiber communication...

Problems solved by technology

[0003] In addition, the tensile strength of the existing wires is not enough, and the resistance to natural disasters such as freezing rain and snow is low; the existing photoelectric composite cable has the function of optical fiber communication and power transmission, and can realize various control signals, network signals and power transmission. Transmission, adapting to the needs of multi-network integration of telecommunication network, broadcasting network, Internet and electric power network

However, the temperature rise of this kind of photoelectric composite cable cannot be monitored during operation, and it is easy to cause the whole cable to be damaged due to the temperature rise caused by the increase of the power conductor load.
