Description
Technical field
The present invention relates to technical field of electric power, and in particular to a kind of restorative procedure of transformer insulation oil.
Background technology
With the increasing of power network power consumption, the development of super extra-high voltage electric transmission and transformation technology, the voltage class of transformer, capacity and
Load is increasingly incremental.Transformer safety runs ever more important.Transformer insulation oil is formed by petroleum refining, after the completion of refining
Contain a certain amount of sulphur in insulating oil, and sulphur can corrode on transformer as a kind of corrosive medium under the conditions of transformer station high-voltage side bus
Copper winding generation cuprous sulfide, while permeate, pollute wire and transformer insulating paper.Because cuprous sulfide is conductive,
Cause Transformer Winding, turn-to-turn insulation breakdown, have a strong impact on the stable operation of power network.
Typically adsorbed, added using activated carbon, activated alumina for recycling for transformer insulation oil in the past
Irgamet 39 is handled as matal deactivator.The shortcomings that this scheme is that adsorption rate is low, and fails effectively solve deterioration
Transformer insulation oil in it is acid too high the problem of；Although Irgamet 39 can alleviate corrosion, Irgamet 39 belongs to big
Molecular compound, the meeting decomposition caused heat release in ageing process, row are unfavorable for the reparation of oil product on the contrary into oxide.
The content of the invention
In view of the above-mentioned problems, the present invention provides a kind of restorative procedure of transformer insulation oil, specifically comprise the following steps：
A) transformer insulation oil of deterioration filtered, be dehydrated, after degassing process, adsorbent is added by the 10% of oily weight
FZS-Cu (I) while mechanical agitation is carried out, it is 30 DEG C~70 DEG C to control adsorption temp；
B) insulation oil filter Jing Guo a step process, dechlorination inorganic agent NaPEG is added by oily weight 5%, controls dechlorination temperature
For 80 DEG C~120 DEG C；
C) metal deactivator BTA, the transformation after being repaired are added into the insulating oil by b step processing
Device insulating oil.
D) after the transformer insulation oil that above step is handled cools down, is cooled to 50 DEG C~60 DEG C, collection is back to change
Depressor body.
The adsorbent FZS-Cu (I) be molecular sieve soaked in copper salt solution after with lucium, not with transformer
Other components chemically react in insulating oil.
The dechlorination inorganic agent NaPEG is dark brown caused by sodium hydrate solid reacts at 120 DEG C with polyethylene glycol
Color solvent.
The metal deactivator BTA addition is 30mg/kg.
The flow velocity of transformer insulation oil is 20L/min~40L/min in the whole repair process.
The invention has the advantages that the transformer insulation oil of deterioration only needs to handle by easy steps, antichlor is added
Can reverses deterioration process after NaPEG and metal deactivator BTA, extends the service life of transformer insulation oil,
Reduce the consumption to goods and materials, it is economic and environment-friendly.
