Abstract
The utility model provides a transformer tank upper portion flange structure, is monolithic structure, adopts the steel plate stamping shaping, and the shape is right angle form " 7 " font for the longitudinal section, and interior angle and exterior angle are the long square frame of fillet. Interior angle and exterior angle are the transition of glossy circular arc, compact structure, pleasing to the eye, fluted on the horizontal ring face of flange, the recess on the horizontal ring face is used for the installation location of sealing strip, and the sealing strip can not take place to shift behind upper portion flange and the casing cover connection, and the fastener can not cause destruction to the sealing strip, has improved the sealed effect of sealing strip greatly, the horizontal ring face upper groove of flange outwards has the bolt hole, the horizontal ring off -plate edge of flange is equipped with ascending hem for the life who improves the strength of flange and shelter from the radiation of sunlight to the sealing washer, extension sealing washer. The upper portion flange of this kind of structure need not the welding, and simple manufacture, simple to operate, province's material save time, seal effectually, and mechanical strength is high, has improved production efficiency, can not produce oil leak, oil impregnate phenomenon.
Description
Technical field
This utility model is related to a kind of oil immersion-type distribution transformer, especially relates to a kind of oil immersion-type distribution transformer fuel tank
Upper flange structure.
Background technology
Oil immersion-type distribution transformer casing upper flange structure generally used now by angle steel welding forming, in angle steel one plane
It is welded with two circle round steel, middle placement sealing strip, round steel plays position-limiting action, and on sealing strip side, surrounding is distributed a round and is used for and case
The connection of lid is used.This structure there is problems that：Because sealing strip does not have standard in casing, case lid are by flange connection procedure
True is spacing, and sealing strip shifting phenomena often occurs；Easily encountering securing member causes sealing strip damaged, leads to sealing effectiveness not
Good；Easily crack is produced when grinding process is in lifting, thus causing oil leak, permeability phenomenon during the welding of angle splice joint face；Circle
Steel and angle steel can produce the solid phenomenon of not prison welding in welding because angle steel phosphorus content is too high in welding.Above-mentioned phenomenon is being given birth to
Repeatedly repair during product, reduce production efficiency, have impact on the quality of product.
Content of the invention
The purpose of this utility model is to overcome shortcoming present in prior art, provides a kind of oil immersion-type distribution transformer
Fuel tank upper flange structure, this transformator upper flange structure is monolithic construction, one time punching molded using steel plate.This
The oil immersion-type distribution transformer casing upper flange of structure, have making simple, easy for installation, save material save time, good sealing effect,
The advantage of high mechanical strength.
To achieve these goals, the technical solution adopted in the utility model is as follows：A kind of oil tank of transformer upper flange
Structure, is monolithic construction, using steel plate punched molding, is shaped as longitudinal section rectangular shape " 7 " font, interior angle and exterior angle are
The rectangle framework of fillet, the horizontal component of " 7 " font is horizontal anchor ring；
Further, fluted, for installing location sealing bar on the horizontal anchor ring of flange；
Further, the horizontal anchor ring upper groove of flange outwards has bolt hole；
Preferably, the horizontal anchor ring outward flange of flange is provided with flanging upwards, for improving strength of flange and blocking daylight
Radiation to sealing ring, extends the service life of sealing ring.
The beneficial effects of the utility model are：Transformator upper flange structure is monolithic construction, is pressed into using steel plate stamping
Type, centre is provided with groove and positions for the installation of sealing strip, and after upper flange is connected with case lid, sealing strip will not be shifted over, tightly
Firmware will not damage to sealing strip, substantially increases the sealing effectiveness of sealing strip；Outward flange flanging upwards, improves method
Blue intensity and block the radiation to sealing ring for the daylight, extends the service life of sealing ring.Interior angle and exterior angle are smooth circular arc
Transition, compact conformation, attractive in appearance.The upper flange of this structure need not be welded, and making is simple, easy for installation, save material saves time, seals
Effect is good, and high mechanical strength improves production efficiency, will not produce oil leak, permeability phenomenon.
Brief description
For the technical scheme being illustrated more clearly that in this utility model, embodiment will be described below used in attached
Figure do simple introduce it should be apparent that, drawings discussed below is only an embodiment of the present utility model, for this area
For those of ordinary skill, on the premise of not paying creative work, other accompanying drawings can also be obtained according to these accompanying drawings.
Fig. 1 is this utility model embodiment oil immersion-type distribution transformer casing upper flange structural representation, and Fig. 2 is oil immersion
Formula distribution transformer container body upper flange longitudinal section close-up schematic view.
Description of reference numerals：1- oil tank of transformer upper flange structure, the horizontal anchor ring of 2-, 3- groove, 4- bolt hole, 5- folding
Side, 6- interior angle, 7- exterior angle.
Specific embodiment
For a further understanding of this utility model, with reference to the accompanying drawing in this utility model embodiment, new to this practicality
Scheme in type embodiment is clearly and completely described.
Referring to shown in Fig. 1, Fig. 2, embodiment of the present utility model, a kind of oil tank of transformer upper flange structure 1, for entirety
Formula structure, using steel plate punched molding, is shaped as longitudinal section rectangular shape " 7 " font, and interior angle 6 and exterior angle 7 are the length of fillet
Square frame；Fluted 3 on the horizontal anchor ring 2 of flange, for installing location sealing bar；Horizontal anchor ring 2 upper groove of flange to
There is outward bolt hole 4；Horizontal anchor ring 2 outward flange of flange is provided with flanging 5 upwards, for improving strength of flange and blocking daylight pair
The radiation of sealing ring, extends the service life of sealing ring.
The beneficial effects of the utility model are：Transformator upper flange structure 1 is monolithic construction, is pressed into using steel plate stamping
Type, centre is provided with groove 3 and positions for the installation of sealing strip, and after upper flange is connected with case lid, sealing strip will not be shifted over,
Securing member will not damage to sealing strip, substantially increases the sealing effectiveness of sealing strip；Outward flange flanging 5 upwards, improves
Strength of flange and block the radiation to sealing ring for the daylight, extends the service life of sealing ring.Interior angle 6 and exterior angle 7 are smooth
Arc transition, compact conformation, attractive in appearance.The upper flange of this structure need not be welded, and makes simple, easy for installation, province material province
When, good sealing effect, high mechanical strength, improve production efficiency, oil leak, permeability phenomenon will not be produced.
It should be pointed out that of the present utility model embodiment is described above.However, it should be appreciated by those skilled in the art,
