Description
Technical field
This utility model is related to transformer manufacture technology, more particularly to a kind of transformator of control leakage field.
Background technology
As power system develops to super extra-high voltage, Large Copacity, remote direction, Large Copacity AC transformer and direct current become
Depressor will be used widely.The usual leakage magnetic flux of high-power transformer is very big, and leakage magnetic flux enters hardware, produces additional damage
Inside transformer hardware local pyrexia is consumed and caused, if temperature is too high, will accelerate to contact the aging of oil.Transformation
Device oil starts to decompose when more than 140 DEG C~150 DEG C, forms alkane, alkene and hydrogen and is reflected in the gas chromatographic analysiss of oil,
Transformator is affected normally to run.Additionally, the leakage field of high-power transformer is connected with greatly forms closure magnetic force by fuel tank
Loop, causes transformer box wall overheated.With the increase of leakage field, transformator saves up and down connecting bolt inside and produces substantial amounts of vortex
Loss and magnetic hystersis loss, cause hot-spot, and this phenomenon is all the more obvious with the increase of transformator single-column capacity.Cause
How this, carry out leakage field control to high-power transformer, it is to avoid it is current art difficulties hot-spot phenomenon occur.
The content of the invention
For the problems referred to above, this utility model provides a kind of transformator of control leakage field.
To solve the above problems, the technical scheme that this utility model is taken is：A kind of transformator of control leakage field, including setting

Cover and be layed in respectively bar shaped magnetic shield and be arranged at up and down that copper shield upper and lower ends are made up of at least one magnetic shield bar
The L-type copper coin that section case is connected at copper shield.
The magnetic shield of lobe of the lung type can solve the problems, such as inside transformer hardware hot-spot, copper shield, bar shaped magnetic shield
Oil tank of transformer can be solved the problems, such as with L-type copper coin and save connecting bolt hot-spot up and down.
Described magnetic shield bar is layed in copper shield surface by the bent plate of its surrounding, and copper shield is provided with opening, bent plate
It is welded on inner wall of oil tank through opening.
Described magnetic shield bar is wrapped up from inside to outside by paper groove and cardboard, it is ensured that bar shaped magnetic shield surrounding occurs without wedge angle
Electrode, and by without latitude glass tape colligation.
One end is provided with ground strip and is grounded by bolt on inner wall of oil tank on described magnetic shield bar.
Described bar shaped magnetic shield is formed around rustless steel round steel and rustless steel round steel is welded by pin with inner wall of oil tank,
Carry out corner shielding.
Described L-type copper coin is welded with copper strips, and copper strips internal package has glue stick, and using glue stick elasticity L-type copper coin is ensured
Reliable contacts after on the transformer lower section is installed, it is to avoid transformator saves up and down connecting bolt and case along appearance because of leakage field concentration of local
The problems of excessive heat of generation.
At least one of which insulating barrier is provided between described magnetic shield bar and transformer body, prevents from becoming for improving electric field
There is shelf depreciation in depressor.
Described insulating barrier is layered by insulated bolt and at least one insulating nut, and is welded in oil tank of transformer
On wall.
Described lobe of the lung type magnetic shield is divided into tri- kinds of thickness of 50mm, 65mm and 80mm according to transformer capacity difference.
By this utility model can effectively solving inside transformer hardware hot-spot and oil tank of transformer and
Connecting bolt hot-spot problem is saved up and down.
