Description
Technical field
The present invention relates to a kind of insulator pollution monitoring method, belong to insulator salt density monitoring field.
Background technology
The surface of ceramic insulator and glass insulator in the process of running can continuous contamination, with the increasing of pollution level
Plus, the conductance of insulator surface also constantly increases, and development is possible to cause pollution flashover phenomenon to a certain extent, to power system
Safe operation is very harmful.Electric insulator pollution flashover, is to hinder one of problem of safe operation of power system.Ceramic insulator and
The application of glass insulator, not changing fundamentally prevents importance of the pollution flashover problem in power system.In order to prevent dirt
Flash the generation of elephant, now using applying, the measure such as wipe, climb to clear up pollution severity of insulators, therefore grasp external insulation pollution in time
Degree, is the necessity of reasonable arrangement insulator surface cleaning work.
Current power transmission line measurement salt is close mainly two methods, and one kind is to utilize insulator leakage current measurement salt close, separately
One kind is close using laser sensing technology measurement salt.
The drawbacks of close method of leakage current measurement salt is present, it is inapplicable in DC power transmission line.
The close method of laser sensing technology measurement salt has the disadvantage that optical sensing part cost is high, and laser sensing technology is measured in addition
The close device of salt is on tower bar, and device is not in same electric field environment with charged insulating, therefore is unable to direct measurement
The salt of charged insulating is close.
Patent No. 201620526120.X patent application, it is proposed that cause optical signal when getting dirty using nuditing fiber
Decay this principle, by monitoring the decay intensity changing value of optical signal caused by the dunghill being attached on insulator surface,
To calculate the insulation pollution degree on insulator umbrella, so as to draw insulator salt density value.The benefit of this principle is simple straight
Connect, but harm is, thus optical fiber be contaminated.When the optical fiber got dirty is monitored again, because optical fiber is got dirty, its performance
It is affected, influences the accuracy monitored again.If cleaned to optical fiber, because insulator is located at eminence, cleaning is very
Inconvenience.
The content of the invention
The self-cleaning insulator pollution monitoring method based on optical fiber can be realized it is an object of the invention to provide a kind of.
To achieve the above object, the present invention uses following technical scheme：
A kind of insulator pollution monitoring method based on optical fiber, it includes insulator stem and insulator umbrella, in the insulation
The surface of sub- full skirt sets and monitoring optical fiber is set in annular groove, annular groove, and monitoring optical fiber includes fiber cores and is wrapped in light
The transparent watertight dope layer of fibre core outer surface, described transparent watertight dope layer by following weight than component constitute：Pure the third the third
Olefin(e) acid emulsion 50-60, coalescents 2-4, water 13-15, the accumulation of salt in the surface soil inhibitor 1-4, preservative 0.2-0.4；Described monitoring optical fiber
The light decay cut signal received is sent into optical receiver, optical receiver fills the light decay cut signal received by wireless transmission
Transmission is put to remote control terminal.
Also include the Teflon that parts by weight are 2-10 in described transparent watertight dope layer.
Described optical receiver and wireless launcher are located on the shaft tower residing for insulator.
Described transparent watertight dope layer by following weight than component constitute：Pure third acrylic emulsion 55, coalescents
3, water 14, accumulation of salt in the surface soil inhibitor 2, preservative 0.3, Teflon 8.
Using the present invention of above-mentioned technical proposal, optical fiber surface is coated in using transparent watertight dope layer, so due to this
Coating is transparent medium, so it does not interfere with monitoring sensitivity of the optical fiber to deamplification, and contains Teflon in the material
Dragon, so, even if there is dust to stain on optical fiber, can also blow away, so as to play the self-cleaning effect of optical fiber with the wind.
