At, the process that oil liquid conveys downwards be in contact with it can generate oil liquid in circular ring shape slowly push aside the phenomenon that, this be in order to avoid
Insulating oil forms heat and electrostatic since fierce collision occurs between components for height fall during conveying, prevents height
Mild electrostatic can cause the chemical attribute of insulating oil and physical attribute changes and causes transformer short-circuit, and strainer and No.1 are filtered
Plate, No. two filter plates, No. three filter plates are the filtration supports of pore size filter not etc., are mainly used for filtering remaining a small amount of in insulating oil
Impurity glues the plate that powder plate is similar sponge structure, can be in the flour in the moment absorption oil liquid that oil liquid passes through, bubble
Pipe then can be realized the substance of oil liquid with sacculus and separate, and principle is similar with cell wall exchange principle, oil liquid can by bubbler tube and
Sacculus continues circulation downwards, and it is for clearance that impurity is then intercepted and stays in structure etc..
Beneficial effect
In terms of the present invention is applied to mining area transformer technology, primarily to solving the storage of transformer insulation oil, fortune
Defeated and operation and maintenance require to implement in mining area, and the miberal powder in mining area is mixed into oil dielectric strength can be made to be greatly lowered,
The problem of short circuit causes transformer explosion will occur when its dielectric strength is reduced to certain value；
The present invention solves this problem by filtering out mechanism equipped with miberal powder in structure, since transformer is in mining area ring
In border, so inevitably entrainment miberal powder is mixed with insulating oil, miberal powder, which filters out mechanism and changes previous insulating oil, to be directly injected into
And the structure used, the miberal powder for being changed to filter out by series of process such as precipitating, sieving, sedimentation, separation, filterings in oil liquid and
Other impurity filter out a part of miberal powder by vibrating screen, then realize that sedimentation, separation, isolation act via settler, finally utilize filter
It effectively prevents causing insulation performance to become due to the purity decline of insulating oil using standard except device reaches the purity of insulating oil
Low and generation the problem of cause transformer fault.

No. three filter plates 40 form, and 31 bottom of rotation conehead is equipped with strainer 32 and is connected through strainer 32 with central spindle 37,37 bottom of central spindle
It is successively arranged 38, No. two filter plates 39 of No.1 filter plate and No. three filter plates 40 from top to bottom, revolves conehead 31 for triangle circular cone composition, in oil
The process that liquid conveys downwards, which is in contact with it, can generate the phenomenon that oil liquid is slowly pushed aside in circular ring shape, this is in order to avoid insulating oil exists
Heat and electrostatic are formed since fierce collision occurs between components for height fall during conveying, prevents high temperature and electrostatic
The chemical attribute of insulating oil can be caused and physical attribute changes and causes transformer short-circuit, strainer 32 and No.1 filter plate 38, two
Number 39, No. three filter plates 40 of filter plate are the filtration supports of pore size filter not etc., are mainly used for filtering remaining a small amount of in insulating oil
Impurity glues the plate that powder plate 33 is similar sponge structure, can be in the flour in the moment absorption oil liquid that oil liquid passes through, gas
Bubble pipe 35 is separated with the substance that sacculus 36 then can be realized oil liquid, and principle is similar with cell wall exchange principle, and oil liquid can pass through gas
Bubble pipe 35 continues to circulate downwards with sacculus 36, and impurity is then intercepted and to stay in structure interior etc. for clearance.
When the transformer to mining area adds insulating oil, oil liquid is perfused from the gravity pipe 10 that miberal powder filters out mechanism 3 to heavy
It realizes in shallow lake case 11 and precipitates for the first time, least a portion of impurity, which can hang, to be stayed in settling tank 11, and remaining oil liquid passes through petroleum pipeline 12
Into in oil liquid sedimentation device 13, first step oil liquid containing miberal powder is pressed under the effect of compass screen surface high frequency small amplitude oscillation by vibrating screen 2
Density stratification, second step is realized by settler 23 is separated by solid-liquid separation isolated operating process, by the oil of the circulation sedimentation of separation bin 28
Oil liquid is simultaneously separated with miberal powder using isolation cabin 29 and is conveyed oil liquid down by conveying seat 30 by liquid, and third portion is all
Oil liquid is unified and successively blocks through filter screen 32, bubbler tube 35, sacculus 36, the filter plate 40 of filter plate 39, three of No.1 filter plate 38, two
Cutting will filter out comprising the included substance of all nonisulated oil including miberal powder, and then insulating oil is filled by the injection of oil return pipe 14
Sap cavity 16 can be used to the use of the electric power assembly in transformer.
