Abstract
Structure of mining flame proof dry -type transformer shell, including cylinder bellows box, the ripple of bellows box be longitudinal arrangement, and the equidistance welding has an outer reinforcing ring on the outer wall circumference of bellows box, and middle part between the adjacent outer reinforcing ring corresponds is equipped with on the inner wall circumference of bellows box the welding has an interior reinforcing ring, and the outer wall of bellows box and inner wall weld respectively on the circumference of tip from top to bottom has outer reinforcing ring and interior reinforcing ring. The utility model discloses technical scheme has effectively improved holistic rigidity of bellows box and intensity, and intensity distribution is even, and outer reinforcing ring and interior reinforcing ring are made very easily, have simplified technology, have higher spreading value.
Description
Technical field
The utility model relates to a kind of transformer case, is a kind of Mine Explosion-proof Dry-type Transformer Enclosure specifically.
Background technology
Mine explosion-suppression dry-type transformer is a kind of transformer generally applied in the mine with gas and coal dust explosion hazard, and this mining transformer adopts intensity high usually, the bellows shell mechanism of good heat dissipation effect.Be limited to underground coal mine environmental factor, flameproof dry type transformer should reduce the overall dimension of product as far as possible.With the increase of product capacity, heat dissipation problem is particularly outstanding, and Large Copacity flameproof dry type transformer adopts Long Circle all-wave line core structure for this reason.
Due to the particular surroundings of flameproof dry type transformer, there is higher requirement to the structural strength of flameproof dry type transformer explosion-proof casing.At present, the fixed form of full bellows is generally support bar and fixes, and its complex process, manufacture difficulty is large.
Utility model content
The purpose of this utility model is exactly the problems referred to above existed for prior art, and design a kind of flameproof enclosure of flameproof dry type transformer, uniform intensity distribution, manufacturing process is simple.
The purpose of this utility model is realized by such technical scheme, the structure of mine explosion-suppression dry-type transformer case, comprise cylindrical shape bellows casing, the ripple of bellows casing is longitudinal arrangement, it is characterized in that the outer wall of bellows casing is circumferentially equidistant and be welded with outer stiffening ring, the inwall being provided with bellows casing of the middle part correspondence between adjacent outer stiffening ring is circumferentially welded with inner stiffener ring, the outer wall of bellows casing and inwall upper and lower end parts be circumferentially welded with outer stiffening ring and inner stiffener ring respectively.
As preferably, the spacing being welded on the outer stiffening ring of outer wall of bellows casing is 400mm-600mm.
The utility model adopts outer stiffening ring and inner stiffener ring to strengthen tubular bellows casing, it is very easy to processing, first roll with corrugated plate and be welded into cylindrical shape bellows casing, then weld with the outer wall of outer stiffening ring at bellows casing, circumferentially evenly distributed, then weld with the inwall of inner stiffener ring at bellows casing, the middle part of inner stiffener ring between adjacent outer stiffening ring.
The beneficial effects of the utility model are: technical solutions of the utility model effectively improve the Rigidity and strength of bellows casing entirety, uniform intensity distribution, and outer stiffening ring and inner stiffener ring are very easy to make, and simplify technique, have higher promotional value.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, utility model is further illustrated.
Fig. 1 is the main TV structure schematic diagram of the utility model embodiment.
Fig. 2 is the plan structure schematic diagram of the utility model embodiment.
In figure: 1, bellows casing 2, outer stiffening ring 3, inner stiffener ring.
Embodiment
Below in conjunction with drawings and Examples, further non-limiting description is done to the utility model:
In Fig. 1 and Fig. 2, the structure of mine explosion-suppression dry-type transformer case, comprise cylindrical shape bellows casing 1, the ripple of bellows casing 1 is longitudinal arrangement, the outer wall of bellows casing 1 is circumferentially equidistant is welded with outer stiffening ring 2, the spacing being welded on the outer stiffening ring of outer wall of bellows casing is 500mm, the inwall being provided with bellows casing 1 of the middle part correspondence between adjacent outer stiffening ring 2 is circumferentially welded with inner stiffener ring 3, the outer wall of bellows casing 1 and inwall upper and lower end parts be circumferentially welded with outer stiffening ring 2 and inner stiffener ring 3 respectively.Technical solutions of the utility model effectively improve the Rigidity and strength of bellows casing 1 entirety, uniform intensity distribution, uniform intensity distribution, and outer stiffening ring 2 and inner stiffener ring 3 are very easy to make, and simplify technique, have higher promotional value.
