Problems solved by technology

[0004] Regardless of whether it is a power cable used in a railway power supply system or a power cable used in other power supply systems, the core of the cable will heat up under the action of its own resistance due to the large current passing through it. The longer the time, the higher the temperature and the higher the resistance. The larger the temperature, the easier it is to generate heat, which will not only cause power transmission loss, but also lead to degradation of in

Abstract

The invention discloses an intelligent sensing photoelectric composite cable, a conductor shielding layer, an insulating layer and an insulating shielding layer are arranged outside a cable core, andat least one communication optical fiber is inserted between metal wires of a metal wire shielding layer in a shielding structure; and an isolation sleeve is arranged on the shielding structure, a steel wire armor layer is arranged on the periphery of the isolation sleeve, and at least one temperature measuring optical fiber is arranged between steel wires of the steel wire armor layer in an inserted mode. The temperature measurement optical fiber comprises a temperature measurement fiber core, a temperature measurement cladding and a heat conduction layer, and heat conduction filling paste isloaded between the heat conduction layer and the metal outer pipe; the heat conduction filling paste comprises the following components in percentage by weight: 18%-20% of a gelatinizing agent, 3%-5% of an oil separation inhibitor, 1%-2% of an antioxidant, 2%-2.5% of a water absorbent, 0.0015%-0.002% of a defoaming agent and the balance of heat conduction oil. The cable can realize real-time intelligent monitoring of the power load operation condition of the cable, ensures synchronization of power supply, communication and online monitoring, and has the advantages of reasonable structure andreliable use.

Description

technical field [0001] The invention belongs to the technical field of power cables, and in particular relates to a power cable capable of transmitting electric energy and information and monitoring operating temperature in a timely manner. Background technique [0002] Power cables are cables used to transmit and distribute electric energy. Power cables are widely used in urban underground power grids, railway power lines, internal power supply in industrial and mining enterprises, and underwater power transmission lines in rivers and seas. The continuous expansion of the application field of power cables has also made the laying environment of power cables more complicated. Power cables have developed from simple power transmission to multi-functional and multi-purpose. functions such as water and moisture resistance, and requires both the transmission of power and the role of communication information. Especially with the acceleration of the development of smart grid con...
