Principle of the present invention is described as follows:
Exhaustion creep damage capability when the mechanical performance of composite insulator is meant the tensile failure load-bearing capacity in short-term of composite insulator and long-time running.It represents the life-span that can also normally move under the situations such as insulator does not rupture, comes off.
The electric property of composite insulator mainly refers to its insulation property, by practical operating experiences as can be known, when the insulation property of insulator take place to destroy, can produce conductive defect, local heating phenomenon occur, and should heating phenomenon can be not in time change and complete obiteration, thereby in conjunction with the characteristics of generating heat, the local pyrexia phenomenon of monitoring insulator just can capture the state of insulator performance change.
Optical fiber sensing technology be follow the development of optical fiber and Fibre Optical Communication Technology and develop rapidly a kind of be that carrier, optical fiber are the novel sensing technology of medium, perception and transmission outer signals with light.Fiber Bragg grating sensor is with the functional Fibre-Optic Sensors of Bragg grating as senser, its sensing principle is a light sensitivity of utilizing fiber optic materials, space interference striped with ultraviolet light forms the space phase grating in fibre core, according to extraneous physical parameter the influence of reflecting Bragg grating centre wavelength is come the extraneous physical values of inverse detection.The influential physical quantity of Bragg grating centre wavelength there are two kinds: temperature and stress, and the variation of Bragg grating centre wavelength and temperature, stress are all linear, because the insulating properties of optical fiber itself, light signal is not subject to characteristics such as electromagnetic environment influence, therefore Fiber Bragg Grating FBG is implanted stress and the variation of temperature that can effectively monitor insulator in the insulator, do not influence the application of insulator in hyperbaric environment simultaneously.
For Fiber Bragg Grating FBG is implanted in the insulator, obtain light sensing effect preferably simultaneously, its production method mainly comprises the next coming in order step:
One, the processing of grating
According to the length requirement of 500kV insulator, 20 gratings of 3 – that evenly distribute in the grating area of coverage on optical fiber, tail optical fiber length keeps 500mm at least, as: in length is on the optical fiber of 4330mm, and 13 gratings evenly distribute in the grating area of coverage.
Two, the encapsulation of optical fiber
Tail optical fiber part at optical fiber puts white sleeve pipe, metal hose and hollow steel bushing from inside to outside successively.
Three, the production of plug
Plug generally is made up of the glass fibre of several ten thousand about 20um of diameter, glass fibre process infiltration in epoxy glue earlier, be pulled through the mould of HTHP then by haulage gear, coming out through overbaking is exactly to be suitable for the plug that insulator is produced, and in the process of producing plug, the ready packaged fiber in front is placed in the glass fibre, together pass through the plug manufacture process of HTHP, packaged fiber, glass fibre will merge fully with epoxy resin, have just made the core rod of insulator of band Fibre Optical Sensor.
Four, following process
Tail optical fiber with packaged fiber strips out from hollow steel pipe earlier, on the low-pressure end gold utensil, punch then, tail optical fiber is stretched out from the hole, carry out the pre-crimping of gold utensil subsequently, again plug is carried out gradation injection moulding and produce, at last the gold utensil on profiled insulation is carried out can obtaining required fiber grating composite insulator after the secondary crimping.
Because the core of this cover technology is to guarantee the survival of optical fiber on the basis of composite insulator not being done big change, and steps such as the high temperature in the production process, gold utensil crimping are easy to cause fractureing of optical fiber, therefore must solve following problem:
One, the encapsulation of optical fiber
On optical fiber, be set with resistant to elevated temperatures white sleeve pipe, metal hose and metal sleeve; as hollow steel pipe; these are designed for the different parts protection optical fiber in insulator, so the strictness design must be carried out in the installation site of each sleeve pipe on the optical fiber, as the installation site requirement of being mentioned among the present invention.
Two, the production of plug
Plug will guarantee that optical fiber can not fracture in the process of producing, also will be placed on the position at plug center as far as possible, is convenient to the processing of later stage sensing data like this.
Three, the strip off of tail optical fiber
Because tail optical fiber in hollow steel pipe, therefore must cut the steel pipe in the plug to strip out tail optical fiber, must be noted that can not sawed-off optical fiber in the process of saw steel pipe.
