Abstract
The invention discloses an upper flange structure of a transformer oil tank. The structure is an integrated structure and is prepared by press forming through adoption of a steel plate. The shape of the structure is a rectangular frame of which longitudinal section is right angle 7-shaped and inner angles and outer angles are rounded angles. The inner angles and outer angles are in smooth circular arc transition and are compact and beautiful in structure. A groove is arranged on the horizontal ring surface of a flange. The groove on the horizontal ring surface is used for mounting and positioning a sealing ring. After the upper flange is connected with a tank cover, the sealing ring will not displace, the sealing ring will not be damaged by a fastening element, and the sealing effect of the sealing ring is greatly improved. A bolt hole is arranged outward the groove on the horizontal ring surface of the flange. Upward folding edges are arranged on the outer edges of the horizontal ring surface of the flange and are used for improving the strength of the flange and shielding radiation of sunlight to the sealing ring, and therefore, the service life of the sealing ring is improved. The upper flange of the structure is unnecessarily welded; the production is simple; the installation is convenient; the material and time are reduced; the sealing effect is good; the mechanical strength is improved; the production efficiency is improved; and the oil leakage and oil impregnation phenomena are avoided.
Description
Technical field
The present invention relates to a kind of oil immersion-type distribution transformer, especially relate 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, is welded with two circle round steel, middle placement sealing strip in angle steel one plane, and round steel plays position-limiting action, and on sealing strip limit, surrounding is distributed a round for the connection use with case lid.This structure there is the problem that owing to sealing strip is the most spacing during casing, case lid are by Flange joint, and sealing strip shifting phenomena often occurs；Easily encountering securing member causes sealing strip damaged, causes sealing effectiveness bad；When grinding process is in lifting, easily produce crack during the welding of angle splice joint face, thus cause leakage of oil, permeability phenomenon；Round steel and angle steel are the highest due to angle steel phosphorus content when welding, and can produce the solid phenomenon of not prison welding when welding.Above-mentioned phenomenon is repaired repeatedly when producing, and reduces production efficiency, have impact on the quality of product.
Summary of the invention
It is an object of the invention to overcome shortcoming present in prior art, it is provided that a kind of oil immersion-type distribution transformer fuel tank upper flange structure, this transformer upper flange structure is monolithic construction, uses steel plate one time punching molded.The oil immersion-type distribution transformer casing upper flange of this structure, has and makes simple, easy for installation, province's advantage that material saves time, good sealing effect, mechanical strength are high.
To achieve these goals, the technical solution used in the present invention is as follows: a kind of oil tank of transformer upper flange structure, for monolithic construction, uses steel plate punched shaping, being shaped as longitudinal section rectangular shape " 7 " font, interior angle and exterior angle are the rectangle framework of fillet；
Further, fluted on the horizontal anchor ring of flange, it is used for location sealing bar is installed；
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 the daylight radiation to sealing ring, extends the service life of sealing ring.
The invention has the beneficial effects as follows: transformer upper flange structure is monolithic construction, employing steel plate punched is molded, centre is provided with groove and positions for the installation of sealing strip, after upper flange is connected with case lid, sealing strip will not be shifted over, sealing strip will not be damaged by securing member, substantially increases the sealing effectiveness of sealing strip；Outward flange flanging upwards, improves strength of flange and blocks the daylight radiation to sealing ring, extending the service life of sealing ring.Interior angle and exterior angle are smooth arc transition, compact conformation, attractive in appearance.The upper flange of this structure without welding, make simple, easy for installation, save material save time, good sealing effect, mechanical strength is high, improves production efficiency, will not produce leakage of oil, permeability phenomenon.
Accompanying drawing explanation
For the technical scheme being illustrated more clearly that in the present invention, accompanying drawing used in describing embodiment below does simple introduction, apparently, drawings discussed below is only one embodiment of the present of invention, for those of ordinary skill in the art, on the premise of not paying creative work, it is also possible to obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is embodiment of the present invention oil immersion-type distribution transformer casing upper flange structural representation, and Fig. 2 is oil immersion-type distribution transformer casing 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-flanging, 6-interior angle, 7-exterior angle.
Detailed description of the invention
In order to be further appreciated by the present invention, below in conjunction with the accompanying drawing in the embodiment of the present invention, the scheme in the embodiment of the present invention is clearly and completely described.
See shown in Fig. 1, Fig. 2, embodiments of the invention, a kind of oil tank of transformer upper flange structure 1, for monolithic construction, use steel plate punched shaping, be shaped as longitudinal section rectangular shape " 7 " font, interior angle 6 and exterior angle 7 are the rectangle framework of fillet；On the horizontal anchor ring 2 of flange fluted 3, it is used for location sealing bar is installed；Horizontal anchor ring 2 upper groove of flange outwards has bolt hole 4；Horizontal anchor ring 2 outward flange of flange is provided with flanging 5 upwards, for improving strength of flange and blocking the daylight radiation to sealing ring, extends the service life of sealing ring.
The invention has the beneficial effects as follows: transformer upper flange structure 1 is monolithic construction, employing steel plate punched is molded, centre is provided with groove 3 and positions for the installation of sealing strip, after upper flange is connected with case lid, sealing strip will not be shifted over, sealing strip will not be damaged by securing member, substantially increases the sealing effectiveness of sealing strip；Outward flange flanging 5 upwards, improves strength of flange and blocks the daylight radiation to sealing ring, extending 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 without welding, make simple, easy for installation, save material save time, good sealing effect, mechanical strength is high, improves production efficiency, will not produce leakage of oil, permeability phenomenon.
It should be pointed out that, and be described above embodiments of the invention.But; it should be appreciated by those skilled in the art; the present invention is not restricted to the described embodiments; the principle that the present invention is simply described described in above-described embodiment; the present invention also has multiple changes and improvements without departing from the scope of the invention, and these changes and improvements both fall within scope of the claimed invention.
