Abstract
The invention provides the external coating technique of a kind of oil tank of transformer, comprise the steps: 1) fuel tank, combination are become fuel tank, combination change door-plate and surface and oil contaminant compared with the multi-work piece pre-ungrease treatment of advanced person's row；2) degreasing and rust removal: surface and oil contaminant relatively light industry part directly enters groove and carries out room temperature process；3) first washing: normal-temperature operation, workpiece under liquid left and right, front and back, swing up and down；4) second washing: normal-temperature operation, workpiece under liquid left and right, front and back, swing up and down；5) phosphatization；6) hot water embathes: tank liquor temperature is not less than 70 DEG C, time 1～2 min；7) dry up；8) coating prime lacquer: at the inner and outer wall spray-applied primer of casing；9) application intermediate layer paint: the inner and outer wall at casing sprays intermediate layer paint；10) coating finish: at the inner and outer wall spray paint of casing.The external coating technique of the oil tank of transformer of the present invention, the oil tank of transformer surface after external coating is not easy to come off, and can be waterproof antirust, it is not easy to by corrosion.
Description
Technical field
The present invention relates to the external coating technique of a kind of oil tank of transformer, belong to transformer technology field.
Background technology
Oil tank of transformer is the shell of transformator, and built-in iron core and winding are also full of transformer oil, makes iron core and winding leaching
In oil.Transformer oil plays insulation and thermolysis.High-power transformer typically has two fuel tanks, and one is body fuel tank；One
For there being load to wither force feed case, on-load voltage regulation fuel tank is built with shunting switch.This is because shunting switch can produce in operation
Electric arc, if carrying out frequent operation will make the decreasing insulating of oil, therefore sets a single fuel tank shunting switch is independent
Place.
Common oil tank of transformer, by the size of its capacity, has box fuel tank, bell type tank and 3 kinds of bases of sealed fuel tank
This pattern.
(1) box fuel tank (core-hung type fuel tank).Box fuel tank is used for medium and small transformator.This transformator top case lid
Can open, its oil-filled rear gross weight is the heaviest compared with high-power transformer；Therefore, need to examine when the device body of transformator
When repairing, whole transformer belt oil can be carried to the place of crane gear, case lid is opened, hangs out device body, overhaul.
(2) bell type tank.General high-power transformer all uses bell type tank.The device body deadweight of this transformator all exists
More than 200t, gross weight is all at more than 300t, and transport is got up relatively difficult.When carrying out the maintenance of device body, it is not necessary to hang out heaviness
Device body, as long as hanging lighter case shell, can carry out service work.
(3) sealed fuel tank.Sealed fuel tank is that its upper nowel is along it after device body general assembly is fully completed loading fuel tank
Between be not by bolt connect, but be directly welded at～rise, form an entirety, thus realize the sealing of fuel tank.Due to this
Plant Oiltank structure to be welding as one, if therefore scene needs suspended core maintenance will be the most inconvenient；So this transformator transport to on-the-spot and
Run duration does not the most carry out suspended core maintenance, and this will the quality of changes persuing depressor should hold good security.Along with transformer manufacturing
The raising of level, sealed construction is the most gradually used, and high-power transformers more both domestic and external also have started to use this
Structure.
Existing oil tank of transformer surface easily comes off, and easily by corrosion.
Summary of the invention
In place of it is an object of the invention to overcome the deficiencies in the prior art, it is provided that the external coating work of a kind of oil tank of transformer
Skill.
The external coating technique of the oil tank of transformer of the present invention, comprises the steps: 1) fuel tank, combination are become fuel tank, group
Close and become door-plate and surface and oil contaminant compared with the multi-work piece pre-ungrease treatment of advanced person's row；2) degreasing and rust removal: surface and oil contaminant relatively light industry part directly enters
Groove carries out room temperature process；3) first washing: normal-temperature operation, workpiece under liquid left and right, front and back, swing up and down；4) second water
Wash: normal-temperature operation, workpiece under liquid left and right, front and back, swing up and down；5) phosphatization；6) hot water embathes: tank liquor temperature is not less than 70
DEG C, time 1～2 min；7) dry up；8) coating prime lacquer: at the inner and outer wall spray-applied primer of casing；9) application intermediate layer paint:
Inner and outer wall at casing sprays intermediate layer paint；10) coating finish: at the inner and outer wall spray paint of casing.
Described priming paint is selected from epoxy resin coating or phenolic resin coating.
Described intermediate layer paint is selected from epoxy micaceous iron paint；
Described finish paint is selected from polyurethane coating.
The external coating technique of the oil tank of transformer of the present invention, the oil tank of transformer surface after external coating is not easy to take off
Fall, and can be waterproof antirust, it is not easy to by corrosion.
Detailed description of the invention
The external coating technique of the oil tank of transformer of the present invention, comprises the steps: 1) fuel tank, combination are become fuel tank, group
Close and become door-plate and surface and oil contaminant compared with the multi-work piece pre-ungrease treatment of advanced person's row；2) degreasing and rust removal: surface and oil contaminant relatively light industry part directly enters
Groove carries out room temperature process；3) first washing: normal-temperature operation, workpiece under liquid left and right, front and back, swing up and down；4) second water
Wash: normal-temperature operation, workpiece under liquid left and right, front and back, swing up and down；5) phosphatization；6) hot water embathes: tank liquor temperature is not less than 70
DEG C, time 1～2 min；7) dry up；8) coating prime lacquer: at the inner and outer wall spray-applied primer of casing；9) application intermediate layer paint:
Inner and outer wall at casing sprays intermediate layer paint；10) coating finish: at the inner and outer wall spray paint of casing.
Described priming paint is selected from epoxy resin coating or phenolic resin coating.
Described intermediate layer paint is selected from epoxy micaceous iron paint；
Described finish paint is selected from polyurethane coating.
