Description
Technical field
The present invention relates to the electric power safety field, be specifically related to a kind of insulator dielectric performance detection method and device.
Background technology
The used insulator of China's electrical network mostly is porcelain insulator greatly now, the insulating property of new insulator are better, and still along with the operation of transmission line of electricity, insulator can wear out gradually, the insulation resistance of insulator can diminish, insulating property can reduce, and becomes low resistance insulator or zero resistance insulator.Cause the main cause of low resistance insulator to have: one, insulator deterioration, insulator are standing the effect of the gravity load of electric field, circuit and the Nature, sunlight, rain, snow, inevitable deterioration gradually for a long time; Two, insulator surface contamination, pollution layer are moistening, cause the insulator dielectric performance to reduce; If the low resistance insulator degree is on the rise or thunder and lightning with insulator breakdown, then may directly cause insulator to damage, cause occurring zero resistance insulator.Because the existence of the poor insulator of null value, low value has increased the probability that lightning stroke flashover and pollution flashover take place, the power supply reliability of electrical network is descended.When containing the insulator chain generation flashover of poor insulator, its short-circuit current can pass through from insulator inside, and the thermal effect of generation may make insulator steel cap blow, thereby phenomenons such as insulator chain disconnects, lead lands occur, and causes serious accident; Secondly, the existence of a large amount of low resistance insulators has increased the kwh loss of electrical network, and this also is the one side reason that not clear electric weight is lost, and has caused the serious wasting of resources.At low resistance insulator, if surperficial contamination, pollution layer are moistening, then can clear up insulator, if the insulator deterioration, then visual actual conditions are changed and are handled; At zero resistance insulator, usually directly change processing.Therefore to the insulating property of insulator in the transmission line of electricity of operation detect be guarantee that high pressure is defeated, one of the critical problem of distribution line safe operation.
Insulator method for testing performance commonly used at present is charged online detection method, and the method for common online detection insulator performance mainly contains:
Spark fork method: be the most frequently used detection method at present, this method is to contact with insulator according to the spark fork whether producing discharges judges the insulator quality.This method has two shortcomings: it is low that the first need be measured the time-consuming efficient of taking a lot of work of all insulators one by one; It two is that the sound of spark discharge is flooded by corona sound and distance is difficult to listen accurate when detecting.If existing several exist null value or low value phenomenon in the insulator chain, when utilizing spark fork method that other insulators are detected, flashover fault over the ground may take place, jeopardize the personal safety of survey crew, cause the line tripping power outage simultaneously.
Bead electric discharge: be detection method commonly used at present.This method is that the distance when producing discharge by the bead of measuring the insulator two ends judges that the voltage of insulator distributes, thereby judges whether tested insulator is normal.This method will frequently be adjusted the bead distance, and False Rate is bigger.
Thermal infrared imager method: be present more advanced detection method.It is to utilize the thermal effect principle of insulator surface to carry out online detection.This method is very effective to the pollution proof insulator that scribbles semi-conducting glaze.Because during the online charging operation of this type of insulator, the surface current of normal insulation is bigger, temperature rise is higher, and the surface temperature of inferior insulator is easy to identification than the sub low good several years of normal insulation with thermal infrared imager.But for the porcelain insulator of glass insulator or common glaze, its normal surface temperature only differs about 1 ℃ than inferior insulator surface temperature, under the weather conditions and site environment of complexity, measures and difficulty, and precision is difficult to guarantee.
Laser dopper flowmeter vibratory drilling method: the centre of oscillation frequency and just often different characteristics of utilizing the insulator that ftractureed, by external force as knocking iron tower or with ultrasound wave that ultrasonic generator produced, aim at tested insulator or aim at tested insulator with the parabolic type catoptron with lasing light emitter, to evoke the microvibration of insulator, the tested insulator of laser alignment that then the laser dopper flowmeter instrument is sent, according to analysis to the frequency spectrum of the signal that reflects, thereby obtain the centre of oscillation frequency values of this insulator, judge the quality of this insulator in view of the above. but because this instrument detects invalid problem and bulky to uncracked insulator, heavy, use and keep in repair complexity, shortcomings such as cost height have limited its scope of application.
The ultraviolet imagery method: the ultraviolet imagery instrument can directly detect the discharge process before the unit exception temperature rise, is the main method of discharge examination in the world.The ultraviolet imagery instrument is compared with other detection meanss, have and observe advantages such as directly perceived, that foresight is good, observed range is far away, but owing to the ultraviolet imagery instrument costs an arm and a leg, and can only observe stronger discharge signal, so it generally speaking can only be to detect corona, shelf depreciation and electric arc.And the discharge of insulator is very faint, even there is inferior insulator to occur, generally shows as the increase of air ionization, does not occur significantly discharge as yet.Be subjected to ultraviolet imagery instrument CMOS luminous sensitivity and the remote restriction that detects, before the faint air ionization of insulator develops into electric arc, be difficult to observe by the ultraviolet imagery instrument.
As seen, all there is certain defective in above the whole bag of tricks, and, in China, have only prefecture-level above power department that the hot line job personnel are just arranged, therefore can't carry out charged detection to line insulator easily and effectively in no hot line job personnel's prefecture-level following area.Adopt the power failure detection method to mainly contain the megger mensuration at present, but because operation danger coefficient very inconvenient, high-altitude application is very high on shaft tower, often need insulator is taken off from shaft tower, operation is inconvenience very, waste time and energy, cause grid power blackout long detection time, influence the use of electrical network.
