Abstract
The utility model provides a kind of for quickly judging that transformer oil aoxidizes the simulator of stable characteristic, including stainless steel test glass, sealing screw thread, washer, bracket and copper catalyst coil.It is characterized in that effectively avoiding the defects of test period using NB/SH/T0811 oxidation stability of transformer oil method of testing is long and the operating procedure of SH/T0193 rotary bomb oxidation test is more, bleeding oxygen operating process is dangerous; the efficiency that this method improves detection work also protects the safety of testing staff; coloration, pH value, acid value index need to only be detected after the oxidation process of 125h at a temperature of 140 DEG C according to transformer oil using the device; can quick discrimination oxidation stability of transformer oil superiority and inferiority, have extremely wide popularization and application foreground.
Description
Technical field
The utility model relates to transformer oil detection fields, and in particular to one kind is for quickly judging transformer oil oxidation peace
Determine the simulator of characteristic.
Background technique
The anti-oxidant and anti-aging property of transformer oil is very important index, is that transformer oil service rating divides
The main foundation of important foundation and transformer manufacturer selection transformer oil.Failure in the operation of the transformer removes itself
Outside Insulation Problems, there is direct relationship with the anti-oxidant and anti-aging of transformer oil.Transformer oil is in running temperature condition
Under, because being influenced by dissolution oxygen, electric field, electric arc and moisture in the oil, impurity and metallic catalyst etc., it may occur that aoxidize, split
The chemical reaction such as solution, generates the oxidation products such as peroxide and alcohol, aldehyde, ketone, acid, and it is insoluble to generate greasy filth etc. using condensation reaction
Object, these oxidation products can reduce the insulation performance of oil, and insulation system and heat dissipation performance to transformer cause fatal influence.
Oxidation stability of transformer oil detection at present is wanted according to NB/SH/T0811 oxidation stability of transformer oil method of testing
It asks, there are the problems that test period is up to 500h, and presently, there are operations to walk for the test method of SH/T0193 rotary bomb oxidation test
The problems such as rapid more, bleeding oxygen operating process is dangerous, up to now, no fast and convenient method, judge that transformer oil oxidation is stable
The superiority and inferiority of characteristic.Therefore, how to solve the problems, such as that this becomes one of those skilled in the art's urgent problem to be solved.
Summary of the invention
It is excessively cumbersome and the problems such as test period is long for existing oxidation stability of transformer oil detection method, according to
The principle that temperature accelerates oxidation process is improved on the basis of the true running temperature of transformer, is proposed a kind of for quickly judging to become
Depressor oil aoxidizes the simulator of stable characteristic, only needs transformer oil through the oxidation of 125h at a temperature of 140 DEG C using the device
Coloration, water soluble acid (pH value), acid value are detected after journey, that is, can determine whether that transformer oil aoxidizes the superiority and inferiority of stable characteristic, this
The efficiency that method improves detection work also protects the safety of testing staff, prevents inferior transformer oil in advance and uses, tool
There is extremely wide popularization and application foreground.
The specific technical solution of the utility model is:
It is a kind of for quickly judging that transformer oil aoxidizes the simulator of stable characteristic, including stainless steel test glass, cup lid,
Washer, bracket and copper catalyst coil.Wherein stainless steel test glass top is connect by sealing screw thread with cup lid, and bottom is put
There is the copper catalyst coil supported by bracket；The stainless steel test glass and cup lid junction are equipped with washer；
The stainless steel test glass is cylindrical type, and height 10cm, internal diameter 10cm, there is graduated scale in inside, can tolerate high temperature；
Selection cylindrical lab cup is to be able to make the transformer oil in test glass to be heated evenly；Inside has graduated scale to be in order to can be with
The additional amount of more intuitive observation transformer oil simultaneously guarantees copper catalyst coil below transformation oil level；
The copper catalyst coil is the round copper coil of specific shape, and copper wire diameter is about 1mm-2mm, and copper wire needs to use
Carborundum cloth is polished, and after polishing is cleaned, connection forms a circle before and after copper wire to be coiled into the helical form of outer diameter 2cm,
Make it possible to the transformer oil in homogeneous catalyst test glass.
Copper catalyst coil is placed on the bracket in stainless steel test glass, is poured by scale into stainless steel test glass
Stainless steel test glass is connected with washer with cup lid by sealing screw thread, forms sealing device, be put into temperature by surveyed transformer oil
It is set as in 140 DEG C of baking oven, after keeping 125h, is protected from light standing for 24 hours, sediment to be generated is all deposited in bottom, opens
Cup lid takes upper layer transformer oil to measure its coloration, water soluble acid (pH value) and acid value, and the oxygen of transformer oil is obtained by this method
Change degree, the superiority and inferiority of the stable characteristic of oxidation for judging different types of transformer oil.
The utility model is prepared a kind of for quickly judging that transformer oil aoxidizes the simulator of stable characteristic, is improved
The efficiency of detection work also protects the safety of testing staff, prevents the use of inferior transformer oil in advance, has extremely wide
Wealthy popularization and application foreground.
