Problems solved by technology

[0002] At present, the traditional power cable only has a single function of transmitting electric energy. With the development of optical fiber communication, the power industry standard also requires that the communication optical cable be embedded synchronously when laying the power cable to realize the communication function of the power system, but it is independent of the power cable. Communication optical cables usually require more laying work, but also face the problems of unstable performance and easy damage by external forces
In recent years, a variety of optical fiber composite power cables have been developed in the industry. These composite cables integrate a communication optical cable into the cable to realize communication functions, or add a temperature measurement optical cable to realize the functions of temperature data measurement and transmission. Simultaneous transmission of communication signals or simultaneous transmission of electric energy and cable temperature signals, however, the functions of these composite power cables are still relatively single, unable to meet the national functional requirements and performance requirements for smart grids and distribution network automation

Abstract

The invention discloses a multifunctional intelligent cable, comprising a circular first protective layer and a plurality of leads arranged in the cavity of the first protective layer. The first protective layer is provided with a first groove, a second groove and a third groove having openings back facing the leads, wherein the first groove is internally provided with a communication optical cable, the second groove is internally provided with a temperature measurement optical cable, and the third groove is internally provided with a vibration sensitive optical cable. The depth of the first groove is greater than the external diameter of the communication optical cable; the depth of the second groove is greater than the external diameter of the temperature measurement optical cable; and the depth of the third groove is greater than the external diameter of the vibration sensitive optical cable. The multifunctional intelligent cable integrates the functions of electric energy transmission, communication, temperature monitoring, fault locating, external force damage early warning, antitheft early warning, etc.
