Description
Technical field
The utility model belongs to composite insulator detection technique field, relates to a kind of composite insulator hydrophobic nature and migration of hydrophobicity on-line measuring device.
Background technology
Composite insulator has obtained application widely by force because anti-soil dodges performance in China's electric system.According to the incomplete statistics of calendar year 2001, China has become the composite insulator that is only second to the U.S. and has used second big country with regard to usage quantity.The anti-soil that composite insulator is good dodges performance, comes from hydrophobic nature and unique migration of hydrophobicity that its outer insulating material silicon rubber is had.But facts have proved that operating composite insulator is because the influence of factors such as aging, discharge and filthy humidity, its hydrophobic nature and migration of hydrophobicity can take place to descend even forfeiture.The anti-soil that the following general who has surrendered of composite insulator hydrophobic nature and migration of hydrophobicity directly influences power transmission and transforming equipment dodges performance, even the safe operation of the system of threat.
Being used for on-the-spot hydrophobic nature detection system at present mainly is the water spray classification measurement mechanism that Sweden transmission of electricity research institute (STRI, SwedishTransmission Research Institute) proposes.This device has and comprises the common spray bottle and the utility appliance such as microscope, wide-necked bottle, lamp and dip stick that can produce thin water smoke.The water smoke of common spray bottle ejection mostly is fan shape or hollow cone shape, exists shower nozzle and where points to, and water smoke but sprays not situation where.And common spray bottle or do not have spray boom, perhaps spray boom is very short, and perhaps spray boom is a metal material, is difficult to realize online water spray.Use this measurement mechanism need know criterions such as contact angle and water mark (being moisture film) area, be difficult to during in-site measurement use, contact angle and water mark area can't be measured at all.This measurement mechanism mainly is to compare by the state of specimen surface behind the atomized water spray and reference diagram to classify in actual applications, and in fact the method for foundation is a kind of artificial contrast method with the aid of pictures, and bigger to people's subjective judgement dependence, measuring accuracy is low.
The utility model content
In order to improve the deficiencies in the prior art, the utility model provides a kind of composite insulator hydrophobic nature and migration of hydrophobicity on-line measuring device, can carry out online generaI investigation to the hydrophobic nature and the migration of hydrophobicity sexual state of composite insulator, make the line upkeep staff can grasp the hydrophobic nature and the migration of hydrophobicity situation of operating composite insulator objective, accurately, for the maintenance of composite insulator provides foundation, the generation of prevention working line pollution flashover (mist sudden strain of a muscle) accident.
For achieving the above object, the utility model is taked following technical proposals: it is by sprayer, filming apparatus, stationary installation and hydrophobic nature has been installed and the portable computer of migration of hydrophobicity analysis and judgement software is formed.
Described sprayer adopts suppresses the formula sprayer, on request quantitatively (aquifer yield, water outlet scattering angle and the degree of atomization determined) sprays even filled circles cone water smoke, shower nozzle is a metal material, shower nozzle water delivering orifice diameter is the 0.7-1.2 millimeter, aquifer yield be the 0.4-0.9 liter/minute, the water outlet scattering angle is 55 °-70 °, but the whole tested zone of direct radiation has solved a lot of common sprayers and referred to where not spray which problem.Described sprayer spray boom employing is electric, the insulating material of satisfactory mechanical property, and length can be regulated in 0.5-1.5 rice scope.Use the spray boom of this structure can realize remote online water spray.Establish a metal ground loop in spray boom handle the place ahead, the metal ground loop is connected on the shaft tower by earth lead, leakage current is to the injury of the person in the time of can avoiding online the water spray.The water butt of sprayer and inflator all adopt physical strength and the good high-density polyethylene material of insulating property, and the water butt capacity is the 0.5-2 liter.The outlet of sprayer water butt is connected with sprayer switch by proofed sleeve, sprayer handle with spray boom.Proofed sleeve links to each other with suction hose in the water butt in the exit of water butt.Sprayer is provided with safety valve, and is too high to prevent the water butt internal gas pressure.
Described filming apparatus is a digital camera.Digital camera adopts the quiet CCD digital camera of taking pixel value at least 130 ten thousand mutually, having at least 3 Zoom Lens abilities, and the positions such as body of the tower, cross-arm that can according to circumstances hand shooting or be fixed in electric power line pole tower by stationary installation are taken.
Described stationary installation connects camera head by existing multi-functional clamp by connecting link and forms.Filming apparatus can be fixed on various types of shaft tower members by multi-functional clamp,, can regulate the shooting angle of filming apparatus by regulating camera head.
During the online detection of composite insulator hydrophobic nature and animal migration, earlier sensitive parts such as the full skirt of composite insulator to be measured, bar footpath are quantitatively sprayed, with digital camera the composite insulator after spraying is taken pictures then.Can not direct projection during when sunshine to the composite insulator detected part, adopt artificial light source to compensate irradiation, the flashlamp that artificial light source can adopt digital camera to carry.The digital image that digital camera photographs is input to portable computer by USB cable, and the morphological feature value of moisture is carried out software analysis and accurately obtained the hydrophobic nature and the migration of hydrophobicity sexual state of compound inslation sub-surface in half-tone information (information entropy, reflecting rate and spectral magnitude average etc.) by the logarithmic code image and the image.
The moisture of compound inslation sub-surface is just as one by one lens, transparent and reflective, and decline gradually along with the composite insulator surface hydrophobicity, the reflecting power of its surface moisture is also descending gradually, thereby the half-tone information values such as information entropy, reflecting rate, image spectrum amplitude average that are presented as digital image also descend gradually.Thereby, thereby can analyze composite insulator hydrophobic nature and migration of hydrophobicity sexual state by the above-mentioned half-tone information value of image is calculated.For more effective sign composite insulator hydrophobic nature and migration of hydrophobicity sexual state, we have carried out based on the Conjoint Analysis of simply multiplying each other combination and making up based on SVM (support vector machine) above-mentioned each half-tone information value.In addition, decline along with the composite insulator surface hydrophobicity, the form of its surface moisture also gradually by the regular circular water droplet via irregular form water droplet to the transition of irregular form moisture film, thereby also can characterize the hydrophobic nature state of compound inslation sub-surface by the morphological feature value of moisture in the analysis image.
The beneficial effect of this utility model has provided a kind of composite insulator hydrophobic nature and migration of hydrophobicity on-line measuring device, not only solved common detection is difficult to realize online water spray with sprayer problem, and can carry out online generaI investigation to the hydrophobic nature and the migration of hydrophobicity sexual state of composite insulator, break away from people's subjective judgement, improved the precision of measuring.
