Description

A kind of just adjustable type insulating boot voltage withstanding experiment device

Technical field

Experimental instrument technology is the utility model is related to, is specially a kind of just adjustable type insulating boot voltage withstanding experiment device.

Background technology

Voltage-withstand test (puncture test) is to examine electrical equipment, electrical equipment, electric device, electric wiring and electrician's peace Full apparatus etc. bears one of main method of overvoltage ability.Division of labor frequency pressure test and DC break down voltage test two kinds.Power frequency is resistance to Pressure tests its test voltage as one times of tested device rated voltage up to several times, not less than 1000V.Its pressing time：For Equipment using porcelain and liquid as primary insulation is 1 minute, is 5 minutes for the equipment using organic solid as primary insulation, for Voltage transformer is 3 minutes, is 10 minutes for oil immersion power cable.DC break down voltage experiment can be by letting out during different tests voltage The numerical value of leakage current, draw leakage current-voltage response.Electrical equipment is through pressure test it can be found that the part of insulation Defect, make moist and aging.

Direct current and the advantage and disadvantage of ac voltage withstanding experiment：DC break down voltage is tested：It can effectively find humidified insulation, it is dirty etc. whole Volume defect, and the local defect of insulation can be found by the relation curve of electric current and leakage current.It is exhausted due to being pressed under DC voltage Edge electric resistance partial pressure, thus it is possible to more effectively find overhang insulation defect than exchange.Meanwhile because being insulated substantially under DC voltage Dielectric loss is not produced, therefore, DC break down voltage is to the destructive small of insulation.Further, since DC break down voltage should be fed only with very little Leakage current, thus required testing equipment capacity is small, it is easy to carry.Ac voltage withstanding is tested：At 2.5 times of tested device voltage and More than carry out, from the thermal breakdown viewpoint of dielectric loss, can effectively find local ionization's property defect and insulation ag(e)ing Weakness.Capacitance partial pressure is pressed due to main under alternating voltage, therefore being capable of effectively exposure device insulation defect.But exchange is resistance to Press the destructiveness to insulation bigger than direct current, and because test current is capacitance current, so needing the testing equipment of Large Copacity. In summary, DC break down voltage experiment and industrial frequency AC pressure test can effectively find insulation defect, but respectively have feature, therefore Two methods can not be replaced mutually, if necessary, should simultaneously be carried out, be complementary to one another.

For internal pressure vessel, the purpose of pressure test is to test the macro strength of container, examines the compactness of welding point And the sealing property of sealing structure.For external pressure vessel (including vacuum tank), the main purpose of pressure test is to examine weldering The compactness of joint and the sealing property of sealing structure, rather than the stability of external pressure of test container.Pressure test is divided into liquid Pressure experiment and gas pressure test.Because the pressure of pressure test is higher than design pressure, and it is difficult in the material and welding point of container Exempt from there can be some defects, thus the possibility that leakage even cracking occurs for container during pressure test is to arrange completely Remove.From safety considerations, pressure test should preferentially use hydraulic test, for gas, liquid It substantially may be considered incompressible, during hydraulic test, even if container ruptures, will not also cause catastrophic blast Accident.For being not suitable for doing the container of hydraulic test, such as residual liquid is not allow in container, or because structure or support are former Because the container of liquid can not be charged, gas pressure test can be used.Catastrophic failure occurs during to avoid gas pressure test, gas is done in all requirements The container of experiment is pressed, its A, B class welding point must be qualified through 100% ray or ultrasonic examination, and should follow strictly《Content regulation》 With regulations of the GB150 on test pressure, test temperature, test method and safety measure etc..Typically used during hydraulic test Water as test(ing) medium, it is necessary to when can also use and will not cause other liquid of occurrence injury.Austenite stainless steel vessel is used Water should be removed totally after carrying out hydraulic test by water stain, be that should control the chloride ion content of water not when being unable to reach this requirement More than 25mg/L, gas pressure test is gases used to should be dry, clean air, helium or other gases.

At present, the existing device for the pressure-resistant experiment of insulating boot, controllability is poor, inconvenient for use, is unfavorable for promoting Use.
