Aluminum-based carbon fiber composite core wire with real-time temperature measuring function

Abstract

The invention discloses an aluminum-based carbon fiber composite core wire with a real-time temperature measuring function. The aluminum-based carbon fiber composite core wire comprises a core and an aluminum alloy conductor. The core is made by compositing metal aluminum alloy base and carbon fiber material. A plurality of temperature sensing fibers are embedded in the core and are silica fibers with high-temperature resistance. The sensing fibers are coated with modified polyimide coating layers. A copper layer is arranged on the outer surface of the core and covered with pyrolytic carbon layer. The aluminum alloy conductor is hinged around the pyrolytic carbon layer. The aluminum-based carbon fiber composite core wire is anti-electromagnetic interference, high in conductivity, strong in bending strength and extension strength and effective in high-temperature and heat resistance; the temperature sensing fibers serve as sensing elements and transmission signal medium, distributed measurement is achieved, temperature of any positions of the core can be monitored in real time only by adding temperature testing equipment at an interface, and alarm signals are sent out in case of excess temperature.

Description

technical field [0001] The invention relates to a wire for overhead transmission lines, in particular to an aluminum-based carbon fiber composite core wire capable of real-time temperature measurement, and belongs to the technical field of overhead wire manufacturing. Background technique [0002] As the carrier of power transmission, overhead transmission wire occupies an extremely important position in the transmission line. For a long time, steel-cored aluminum stranded wires have been mainly used for overhead conductors. In recent years, my country's industrial and agricultural production has developed rapidly, and the power lines in some areas have not kept up with the needs of development and are in urgent need of renovation. However, based on the constraints of investment costs and investment time, how to use effective corridor resources to increase transmission capacity has become a key issue in power construction. A big subject. For the general methods of increasi...
