Description
Technical field
The utility model relates to a kind of Optical Fiber composite overhead Ground Wire, particularly a kind of Optical Fiber composite overhead Ground Wire with temp sensing function.
Background technology
Optical Fiber composite overhead Ground Wire (OPPC Optical Phase Conductor is called for short OPPC) is a kind of new special optical cable of power communication system, it is the optical cable that in traditional phase line structure, fiber unit is compounded in the lead, can make full use of the line resource of electric power system self, power matching network system particularly makes it to have the dual-use function of electric energy transmitting and communication.The present operating experience in existing 8 years in Europe in the world is applied to reach six over thousands of kilometers by operation in the end of the year 2005 on 35 kilovolts to 420 kilovolts the circuit.
The general structure of OPPC is: many aluminium Bao Gangsi are stranded in internal layer successively, in aluminum cald steel wire, at least also comprise the stainless steel tube that one or more contain optical fiber, the structure of such optical cable can be divided into central tubular and two kinds of primary structures of layer-twisted type again according to the position of stainless steel tube in whole composition phase conductor, wherein central tubular is done center line with the stainless steel tube that is installed in the telecommunication optical fiber unit, make the telecommunication optical fiber unit be positioned at the center of Optical Fiber composite overhead Ground Wire, stranded one or more layers aluminum cald steel wire in outside or aluminum steel; Layer-twisted type is to do to carry out as stranded unit with aluminum cald steel wire line or aluminum conductor stranded with the stainless steel tube unit that is installed in the telecommunication optical fiber unit, and the outside is again with one or more layers aluminum cald steel wire line or aluminum conductor.OPPC makes full use of the line resource of electric power system self, and particularly the power matching network system avoids making it to have the dual-use function of electric energy transmitting and communication in aspects such as frequency resource, route coordination, electromagnetic compatibility and extraneous contradiction.
Although at present abroad in more existing practical experiences of the application of OPPC and history, but worldwide, contactless infrared survey technology (batch (-type)) is generally all adopted in the temperature survey of lead, its operation is subjected to meteorological condition, geographical conditions and artificial execution influence, and all do not have login or record in the true temperature of the inside of continuous measurement lead (on-line measurement constantly) the practical circuit worldwide.Southern especially big ice and snow disaster was around the Spring Festival recognized us in 2008, adds thermometry and be of great importance in the grid power transmission lead, also was simultaneously in order to have realized that the application of electric power special optical cable is from the deep extension of distribution network to electric power transmission network.
The optical fiber temperature-measurement technology is to utilize the light sensitive characteristic of fiber grating, method by ultraviolet irradiation, in fibre core, form the grating of the different periodic distribution of refractive index, the local mirror surface that forms an arrowband is to the light formation reflection of specific wavelength, when the temperature of optical fiber changes, the cycle of grating can change along with expanding with heat and contract with cold of optical fiber, this changes can change reflection wavelength, by measuring catoptrical wavelength change, measures the optical fiber temperature sensor of grating position.
