Description
Technical field
The technical field that the Oxidation Stability that the utility model relates to liquid insulating material is evaluated, particularly relates to a kind of device for oxidation stability of transformer oil rapid evaluation and high-pressure oxidation reaction vessel.
Background technology
In recent years, China's power industry has entered the developing period of bulk power grid, extra-high voltage grid, has in succession built up 1000kV ultra-high voltage AC transmission engineering and ± 800kV extra-high voltage direct-current transmission engineering.Solve a series of basic world-class difficult problem such as the control of ultra-high voltage AC transmission system electro-magnetic transient, insulation configuration, electromagnetic environment, device fabrication under the rigor condition such as high voltage, heavy current, heavy pollution and define complete technical system.Correlation technique is applied in multiple successive projects, and has popularizing application prospect widely, and economic and social profit is remarkable especially, achieves the innovation and breakthrough with milestone significance.
Transformer is extremely important power transmission and transforming equipment in power transmission engineering, and the overall development of its industry development and power industry is closely related.In operation, transformer oil, except the long period effect will bearing high voltage, lightning impulse and switching overvoltage, also will stand the impact of the factor such as high temperature, metal material catalytic oxidation, can cause its decreasing insulating.
Therefore as the transformer oil of predominating insulation in transformer except should possessing good electric property, also should possess good oxidation stability.The antioxygenic property of transformer oil is the very important index of transformer oil, is the important foundation that transformer oil service rating divides, and is also the Main Basis that transformer manufacturer selects transformer oil.
Specifically, transformer oil is one of stock used in power transmission system, in the oil-filled electric equipments such as transformer, reactor, mutual inductor, switch, mainly play insulation and cooling heat dissipation effect.Because electrical equipment is in the defeated change process of electric power, transformer oil can be subject to the impact of the factors such as oxygen, temperature, electric field, metal, insulating material and be oxidized, the chemical reaction such as cracking, generate the oxide such as a large amount of superoxide and alcohol, aldehyde, ketone, acid, generate the insolubless such as greasy filth through condensation reaction again, cause oil quality deterioration, reduce serviceable life.
At present, two classes are mainly contained for the instrument of oxidation stability of transformer oil evaluation both at home and abroad:
One class meets NB SH/T 0811, ASTM D2440 method and IEC61125 method oxidation stability of transformer oil analyzer.
Principle is: at the temperature (100 DEG C, 110 DEG C or 120 DEG C) of regulation, under the catalytic action of copper, within 164 hours or the 500 hours test period of regulation, pass into oxygen or air carries out oxidation test, measure the acid number and precipitation or dielectric dissipation factor that are oxidized rear oil, judged the oxidation stability of transformer oil by the acid number of oxygenated oil and the size of precipitation and dielectric dissipation factor.
The maximum defect of above method is that the test period is comparatively large, is generally all greater than 160 hours.
Another kind of is rotary oxygen bomb instrument, meets ASTMD2112 (SH/T0193) method, is a kind of accelerated test procedures of oxidation stability of transformer oil.
Principle is: tested oil sample, distilled water and copper coil are put into a glass sample holder, then it is put into oxygen bomb, oxygen pressure initial in oxygen bomb is 620kPa, puts into the oil bath of 140 DEG C, subsequently, with the speed axial-rotation of 100 revs/min.When pressure drop is to during lower than top pressure 172kPa, terminate test, the reaction time of record oil and oxygen.

Country transformer oil new standard GB2536-11 formally implements, the oxidation stability of regulation transformer oil carries out 500 h run to evaluate below 120 DEG C, the increase of oxidation stability of transformer oil test period reduces the efficiency of transformer oil development and evaluation, proposes higher requirement to oxidation stability of transformer oil evaluation device security performance.
And existing testing equipment cannot realize the oxidation stability evaluation of transformer oil under short period and lower temperature, become the focal point of industry.
For the deficiency of existing oxidation stability of transformer oil rapid method for assessment, a kind of device for oxidation stability of transformer oil rapid evaluation need be developed.Test temperature is at 120 DEG C and following, and (within 500 minutes) can complete within the very short test period, do with the equipment of employing NB SH/T 0811 method and within 500 hours, compared with oxidation results, there is good consistance, for the Oxidation Stability of rapid evaluation transformer oil provides technical support.
