Description
Technical field
The sub- experimental technique field of High-Voltage Insulation is the utility model is related to, in particular it relates to which a kind of be used for insulator arc-over
The temperature control device of experiment.
Background technology
With the frequent generation of insulator arc-over accident in power system, environmental factor and its composition are special to insulator arc-over
Property influence be gradually taken seriously, domestic and foreign scholars study it Flashover Characteristics of Polluted Insulators influenceed done it is big
Work is measured, certain achievement is also achieved, takes many measures to prevent the generation of insulator pollution flashover.
In influence of the research environment composition haze to Flashover Characteristics of Polluted Insulators, University Of Chongqing Jiang Xing is good et al. develops
Artificial haze room, passes through ultrasonic wave fogger and aerosol generator simulates haze environment.In order to simulate haze experimental condition,
Good et al. the cylindrical enclosure experimental rigs that the high 2m of diameter 1m have been made using lucite of Jiang Xing.Compatibility test device, makes
Particulate and salt fog simulation haze composition caused by ultrasonic humidifier, use laser dust monitor, aerosol caused by combustion method
The ginseng such as the particle concentration of the monitoring of equipment pilot region such as particle diameter spectrometer, Hygrothermograph, conductivity meter, particle diameter distribution, humiture
Number index, and propose the test method under the conditions of the method for simulating haze environment and haze.In experiment, when being humidified by controlling
Between, quantity combusted and fog Solute mass change relative humidity, haze volume mass and mist electrical conductivity, simulated relative humidity
Scope is in 80% ~ 90%, the μ g/m of haze volume mass scope 200 ~ 6003, mist conductivity range it is molten in 1000 ~ 3000 μ s/cm and gas
Glue particle diameter distribution concentrates on 0.25 ~ 2 μm of a variety of haze environment.Result of the test shows, can be produced using the experimental rig various
The controllable haze experimental enviroment of degree, condition, available for probing into affecting laws of the haze to power transmission and transformation equipment outer insulation.
On flashover property analysis of the insulator under salt mist environment of defiling, domestic and foreign scholars have also done numerous studies,
Great role has been risen to the reliability for improving insulator safe and stable operation.Central China University of Science and Technology Wang Yu is fine et al. in artificial pollution
Pollution flashover of the contamination insulator under salt mist environment is simulated in laboratory, obtains three types insulator in difference
Salt is close, pollution flashover voltage and flashover voltage gradient under different salt fog salinity.Result of the test shows：Salt fog is to the flashover voltage of the insulator
Influence it is close much larger than salt, with reference to the filthy situation of coastal reality and sea water conductivity, in the case where high salt is close, under the flashover voltage of the insulator
Drop is no more than 20%, and under high salinity, the flashover voltage of the insulator can decline more than 40%；Thus prove, in coastal area, only to use
Equivalence is tight, close ash is that according to progress external insulating level external insulating level can be made insufficient, accident potential be present.
Although many researchs have been done in influence of the studies in China mechanism to transmission line of electricity external insulation, and consider salt fog, mist
Influence of the factors such as haze to insulator pollution flashover, but considering variation of ambient temperature to insulator pollution flashover research very
It is few.
When research insulator contamination characteristic and insulator make moist process analysis procedure analysis, the temperature of insulator local environment is controlled
Degree, that is, control the temperature of insulator artificial pollution test room.The flashover voltage of insulator is removed by environment temperature in artificial pollution test
Outside degree influences, also with being that insulator and pollution test room temperature difference are closely bound up along the temperature difference.The change of above two factor can change
Become the situation of making moist of insulator surface, the change of damp degree flows through insulator in addition to it can influence the pollution flashover voltage of insulator
The leakage current feature on surface, such as leakage current maximum, peak value of pulse, pulsed discharge amount and leakage current high fdrequency component
Can with cooling method, cooling degree, test method change and change.
In traditional experimental study, insulator temperature and this influence factor of the temperature difference of pollution test room are generally have ignored,
In fact cooling method, cooling degree, test method can all have influence on the situation of making moist of insulator surface.Therefore, with reference to the temperature difference
The situation of making moist of analysis insulator surface is gone, the leak current characteristic for going to analyze insulator surface is particularly important.To coordinate
Each high-tension working condition in artificial pollution test room in high pressure external insulation, while meet the related mark of related external insulation experiment
Alignment request reaches good cooling control effect, it is necessary to cooling control measure reasonable in design in pollution test room.Simulating
Severe hazard weather, as during insulator pollution flashover, the effect of fast cooling should be considered in the case of sudden drop in temperature, it is allowed to fast
Speed is responded to meet insulator damp degree.
