Description
Technical field
The utility model belongs to technical field of vacuum equipment, is a kind of extra-high voltage vacuum oil-filter specifically.
Background technique
In China, extra-high voltage refers to ± 800 kilovolts or more of direct current and the voltage of 1000 kilovolts and the above alternating current
Grade.Following table is " 750kv power transformer, liquid immersed reactor, mutual inductor construction inspection rules " (Q/GDW 122-2005).
As can be seen from the above table, 750KV's or more is higher and higher to the index request of transformer oil, either in water content
Or air content or granularity require all higher.
Vacuum oil-filter traditional at present is designed according to the boiling point different principle of water oil.Vacuum pump is by vacuum tank
Interior air is extracted out to form vacuum, and extraneous oil liquid enters coarse filter under atmospheric pressure, by inlet duct, removes larger
Particle, subsequently into heating tank, the oil by being heated to 40-75 DEG C is pipelined to the atomization in vacuum tank
In structure, oil liquid is rotated very fast by the spray wing in atomization structure is separated into half mist for oil, and the moisture content in oil rapidly flashes to
Vapor is simultaneously continuously sucked in condenser by vacuum pump.Vapor into condenser reverts into water again after cooling and releases,
Oil liquid in heating in vacuum tank is discharged into fine filter by oil drain pump and is filtered out granulometric impurity by filter paper for oil or filter core, thus
It completes vacuum oil-filter and rapidly removes the overall process of well cuts, moisture content, gas, make clean oil from fuel-displaced outside discharge machine.
But rotated very fast just with the spray wing in atomization structure and oil is separated into half mist, the moisture content in oil rapidly steams
It sends out into vapor and is continuously sucked in condenser by vacuum pump, can not be completely by the moisture removal in oil liquid, Ren Ranyou is a small amount of
There are the standards for extra-high voltage oil liquid secondary recovery in oil liquid, is not achieved utilizing for moisture.
Utility model content
The utility model aim is intended to provide a kind of extra-high voltage vacuum oil-filter, can be by water remaining in insulating oil
Divide and impurity completely removes, reaches extra-high voltage insulating oil operation standard.
To realize the above-mentioned technical purpose, the technical solution adopted in the utility model is as follows:
A kind of extra-high voltage vacuum oil-filter, including vacuum separator, the vacuum separator include vacuum separation tank, set
It sets in the atomization recurring structure of vacuum separation tank inner top, the reaction frame being arranged in the middle part of vacuum separation tank, setting in reaction frame
The water-oil separation structure of lower section,
The water-oil separation structure successively includes water-oil separation area, storage area, reserve, the water-oil separation from top to bottom
Area includes the strainer being fixed on vacuum separator inner wall, filter plate, the hydrophilic oleophobic material layer being folded between strainer and filter plate；
First through hole is uniformly provided on the hydrophilic oleophobic material layer, the filter plate opens up on the position opposite with the first through hole
There is the second through-hole, there is one end of a conduit to pass through second through-hole and wraps first through hole；The storage area, reserve
Between separated by the partition being fixed on the vacuum separator inner wall, opened on the position opposite with the second through-hole on the partition
Equipped with third through-hole, the other end of the conduit passes through the third through-hole and extend into the reserve；The filter plate except
Fourth hole is uniformly offered on the position for having the second through-hole, the fourth hole is for being connected to water-oil separation area and water storage
Area.
Utility model by adopting the above technical scheme, oil to be clean first go most of moisture through atomization recurring structure etc.
It removes, the oil for remaining a small amount of moisture drops onto water-oil separation area from reaction frame, enters hydrophilic oleophobic material layer through strainer, hydrophilic
Oleophobic material absorbs the moisture in oil liquid, and oil liquid is flowed into catheter from first through hole, flows ultimately into reserve, and hydrophilic thin
After the water suction of light wood material, due to gravity, moisture can drip down, finally storage area is flowed into from fourth hole, thus by residual
The moisture removal stayed is clean, meets the requirement of extra-high voltage oil.
It further limits, the conduit and the first through hole are interference fit.
What interference fit can avoid having been removed moisture has the gap from conduit and first through hole to be flowed into storage area, makes
Occur at the case where oily waste.
It further limits, is provided with sealing ring between the conduit and the first through hole.
It further limits, is provided with sealing ring between second through-hole, third through-hole and conduit.
Equally, sealing ring also serves identical.
It further limits, the first through hole is nonlinear type through-hole.
Nonlinear type through-hole can increase the time that oil liquid flows in first through hole, allow hydrophilic oleophobic material more
Adequately absorb the moisture in oil liquid.
The utility model, will be oily using the hydrophilic characteristic with oleophobic of hydrophilic oleophobic material by increasing water-oil separation structure
Remaining moisture removal is clean in liquid, achievees the purpose that meet extra-high voltage oil.
