Multifunctional intelligent cable

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 accommodation space in the cavity of the first protection layer except the plurality of leads is a packaging material space, and packing materials, a communication optical cable, a temperature measurement optical cable and a vibration sensitive optical cable are arranged in the packaging material space. The number of the leads is three, and each two leads are in contact. The packaging material space comprises a first portion, a second portion, a third portion and a fourth portion; the first portion, the second portion and the third portion all enclosed by outer walls of two leads and the inner wall of the first protection layer, and the fourth portion is enclosed by outer walls of three leads. The first portion is internally provided with the communication optical cable and packing materials; the second portion is internally provided with the temperature measurement optical cable and packaging materials; the third portion is internally provided with the vibration sensitive optical cable and packaging materials. 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.

Description

technical field [0001] The invention relates to a multifunctional intelligent cable. Background technique [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, and 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 transmissio...

[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
