Abstract
The utility model discloses an explosion-isolating dry type transformer shell for mining, which comprises a front end cover. The front end cover is connected with a front box rim flange, the two ends of a front-segment corrugated pipe are respectively connected with the front box rim flange and a front reinforced flange, the two ends of a middle-segment corrugated pipe are respectively connected with the front reinforced flange and a rear reinforced flange, the rear reinforced flange is connected with a rear box rim flange by a rear-segment corrugated pipe, the rear box rim flange is fixed on a rear end cover, and lifting lugs are arranged on the front reinforced flange and the rear reinforced flange. The front reinforced flange and the rear reinforced flange adopt thick steel plates, and the lifting lugs are directly processed on the reinforced flanges; therefore, when in hoisting, the reinforced flanges can bear forces, the box rim flanges cannot be affected, an explosion-isolating gap cannot be increased, and the requirement for product safety is met. A box body adopts segments of corrugated pipes, the middle part is connected by the reinforced flanges, and the reinforced flanges are arranged on bottom feet and are connected with the bottom feet; the multi-segment type corrugated pipe cannot be drooped and deformed under the function of the gravity of a transformer, which overcomes the disadvantage that the original entire type corrugated pipe can be easily deformed.
Description
Technical field
The utility model relates to a kind of transformer case, be a kind of Mine Explosion-proof Dry-type Transformer Enclosure specifically, it is mainly used on big capacity flameproof dry type transformer and the flameproof mining mobile transformer substation, also can be used as other security performance is had relatively high expectations, need place explosion-proof or that casing rigidity is had relatively high expectations.
Background technology
Be limited to environmental factor under the coal mine, flameproof dry type transformer should dwindle the overall dimension of product as far as possible.Follow the increase of product capacity, heat dissipation problem is particularly outstanding, and big for this reason capacity flameproof dry type transformer adopts Long Circle all-wave line core structure.The casing of this structure is whole joint bellows, and the casing both sides respectively are provided with case along flange.In use, the Heave Here is usually located on the box flange of both sides, because case corrugated thickness of pipe wall is thinner, causes transformer end cap flange and case to increase gradually along flange distortion and can not satisfy the safe handling requirement along flame proof gap between the flange so easily cause case.Whole transformer weight is born on whole joint bellows simultaneously, easily causes the bellows distortion.
Summary of the invention
Goal of the invention: the purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of high strength, on-deformable Mine Explosion-proof Dry-type Transformer Enclosure are provided.
Technical scheme: in order to solve the problems of the technologies described above, the utility model has adopted following technical scheme: a kind of Mine Explosion-proof Dry-type Transformer Enclosure, and it comprises front end housing, front end housing is connected along flange with preceding case; The two ends of leading portion bellows are connected along flange, preceding reinforcing flange with preceding case respectively; The two ends of stage casing bellows are connected with preceding reinforcing flange, back reinforcing flange respectively; Back reinforcing flange is connected along flange with rear cabinet by the back segment bellows, and rear cabinet is fixed on the rear end cap along flange; Reinforcing flange, back reinforcing flange are provided with hanger before described.
In the utility model, preferred, be provided with connecting rod between described preceding reinforcing flange, the back reinforcing flange; As further improving, can be at preceding case along flange, preceding reinforcing flange, back reinforcing flange and rear cabinet along fixed connecting rod between the flange, make shell when lifting, strengthen stress point.
In the utility model, described connecting rod has two at least, and is best for being four, and four connecting rods are distributed on four jiaos of flange, and are stressed even.
Beneficial effect:
1, forward and backward reinforcing flange of the present utility model adopts steel plate, directly processes hanger on reinforcing flange.Hoisting weight increases, and reinforcing flange is stressed during lifting, does not influence case along flange, can not cause the increase in flame proof gap, satisfies the requirement of Product Safety.
2, casing of the present utility model adopts the multistage bellows, the centre connects with reinforcing flange, reinforcing flange places on the footing and with footing and is connected, the bellows of this multisection type can not produce sagging distortion under the transformer action of gravity, overcome the yielding defective of original integral type bellows, prolonged useful life.
3, case of the present utility model carries out welding tractor processing along flange and end corrugation Guan Kexian, with the reinforcing flange splicing, can reduce the explosion suppresion surface distortion that welding causes, and reduce equipment requirements after finishing.
Description of drawings
Be illustrated as structural representation of the present utility model.
Embodiment:
Below in conjunction with accompanying drawing the utility model is done further explanation.
As shown in the figure, Mine Explosion-proof Dry-type Transformer Enclosure of the present utility model comprise front end housing 1, preceding case along flange 2, leading portion bellows 3, preceding reinforcing flange 4, stage casing bellows 5, back reinforcing flange 6, back segment bellows 7, rear cabinet along flange 8 and rear end cap 9.Front end housing 1 is connected along flange 2 usefulness securing members with preceding case; Weld along flange 2, preceding reinforcing flange 4 with preceding case respectively at the two ends of leading portion bellows 3; Weld with preceding reinforcing flange 4, back reinforcing flange 6 respectively at the two ends of stage casing bellows 5.Back reinforcing flange 6 is connected along flange 8 with rear cabinet by back segment bellows 7, and back segment bellows 7 adopts the mode of welding to be connected with back reinforcing flange 6, rear cabinet respectively along flange 8; Rear cabinet also is connected with securing member with rear end cap 9 along flange 8.Reinforcing flange 4, back reinforcing flange 6 are provided with and hang a device-hanger before described.The said apparatus integral solder is on footing.
As improvement, can between preceding reinforcing flange 4, back reinforcing flange 6, be provided with connecting rod, to strengthen its intensity; Best is at preceding case along flange 2, preceding reinforcing flange 4, back reinforcing flange 6 and rear cabinet along welding is with four connecting rods that are cascaded between the flange 8, and described connecting rod has two at least, and the best is four.Four connecting rods are evenly distributed on four jiaos of flange, when improving intensity, make stressed more even.
On reinforcing flange 4 and the back reinforcing flange 6, the lifting angle reduced before lifting rope directly acted on during lifting, and case does not cause forward and backward case to increase along the gap between flange and the front and rear cover along flange 2 and rear cabinet along flange 8 distortion before can not causing.Case was along flange 2, rear cabinet along flange 8, on the preceding reinforcing flange 4, back reinforcing flange 6 before transformer weight directly acted on, and indirectly-acting can not cause the bellows distortion on footing.
The above only is a preferred implementation of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection range of the present utility model.
