Description
Technical field
The invention belongs to the adsorption treatment field of power industry transformer insulation oil, and in particular to rotten in a kind of transformer oil
The in-situ processing device of corrosion sulphur.
Background technology
Power transformer is one of most important equipment in power plant and electric substation, and electricity is carry during electrical power distribution
The tasks such as buckling is changed, electric energy distributes, its good running status are power system security, the reliable, important guarantee of economical operation.
Clean transformer oil can provide good insulation and thermolysis, but it is in the running of transformer, Ke Nengyou
Cause the deterioration of oil in the influence of the factor such as foreign substance pollution or high temperature, electromagnetic field, metal catalytic, produce corrosive
Sulphur.Active sulfur refers to react with metals such as copper, iron, silver under certain condition and cause metal erosion in insulating oil
Sulphur-containing substance, such as elemental sulfur, hydrogen sulfide, mercaptan and thioether.The surface that corrosive sulphur is attached to winding copper can occur instead
Cuprous sulfide should be generated, because cuprous sulfide has conductive characteristic, and wire insulation paper can be penetrated into, transformer can be caused
The horizontal decline of integral insulation, can occur insulation breakdown, cause to burn the major accidents such as transformer when serious.In recent years Guangdong electricity
Net, East China Power Grid and Fujian Electric Power Network have had been found that different degrees of transformer fault caused by active sulfur.
Therefore, the active sulfur in transformer oil is efficiently removed for preventing resulting transformer fault, is extended
Transformer service life has the meaning of reality.What application was more at present is the method for adding matal deactivator, and matal deactivator can
To be reacted with copper, layer protecting film is formed on the surface of copper to prevent active sulfur and copper from continuing to react.But this method master
There are following three problems：1) metal deactivator can not eliminate the active sulfur compound in oil；2) metal deactivator can only be
By suppressing transformer oil sulfur corrosion problem in the range of the regular hour, main cause is metal deactivator in transformer station high-voltage side bus process
In can by internal high temperature, autoxidation, hot localised points etc. act on and gradually be consumed, when metal deactivator is in insulating oil
Content slowly reduce to it is depleted when, cannot play a part of preventing corrosion；3) metal deactivator is in longtime running mistake
Influence in journey to the reason of transformer oil, change performance and electric property is unclear.Another method is exactly to change transformer oil,
It is a kind of uneconomic method but it changes oil every time will spend substantial amounts of manpower financial capacity.Discarded transformer oil also has
Contaminative.And the non-aggressive sulphur in the insulating oil newly changed is partially converted into activity as the operation of transformer also has
Active sulfur, can also damage be produced to Transformer Winding.
