Abstract
The utility model discloses a flange sealing structure for an oil immersed transformer or a reactor, which comprises an upper and a lower flange(1, 2) and a sealing piece(3). The sealing piece(3) is arranged between the upper flange and the lower flange(1, 2); the upper flange and the lower flange(1, 2) are connected through a screw bolt. The utility model is characterized in that a stopper(4) is also arranged between the upper and lower flanges(1, 2). The height of the stopper(4) is the same as the best compressing height of the sealing piece(3). The utility model has the advantages of rigid structure, no need for opening groove on the lower flange(2), and eliminating the flange oil leaking problem due to the grooving. As a stopper(4) is arranged, the utility model can efficiently control the compressing volume of the sealing piece, thereby avoiding the flange oil leaking caused by the compressing aging of the sealing piece.
Description
Technical field
The utility model relates to the flange seal technical field, particularly a kind of oil-filled transformer or reactor flange hermetically-sealed construction that is applicable to.
Background technology
Existing oil-filled transformer or reactor flange hermetically-sealed construction are made up of upper flange, lower flange, seal, and connect by bolt.This structure if the crudy of groove is not high, easily causes flange seepage oil in actual production; If bolted power is too big, the seal conquassation is aging follows the string, also easily cause connect upper flange, lower flange is not parallel, promptly flange is high on one side low on one side, also easily causes flange seepage oil.
Summary of the invention
Goal of the invention of the present utility model provides a kind of decrement that can effectively control seal, avoid seal conquassation aging oil-filled transformer or reactor flange hermetically-sealed construction, to solve the weak point that existing oil-filled transformer or reactor exist with the flange hermetically-sealed construction.
Goal of the invention of the present utility model can realize by following technical measures: a kind of oil-filled transformer or reactor flange hermetically-sealed construction, comprise upper and lower flange, seal, seal is between upper and lower flange, upper and lower flange connects by bolt, it is characterized in that also being provided with between upper and lower flange locating part.
The height of described locating part is the optimal compression height of seal.
The utility model is a rigid structure, and the problem of the flange seepage oil that processing brought of groove has been avoided in the processing of need not slotting on lower flange.Owing to be provided with locating part, the utility model can effectively be controlled the decrement of seal, avoids the aging flange seepage oil that causes of seal conquassation.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Further describe the utility model below in conjunction with accompanying drawing.
A kind of oil-filled transformer shown in Figure 1 or reactor flange hermetically-sealed construction comprise upper and lower flange 1,2, seal 3, locating part 4, and seal 3 and locating part 4 are between upper and lower flange 1,2, and upper and lower flange 1,2 connects by bolt.The height of locating part 4 is the optimal compression height of seal 3, thereby can control the decrement of seal 3 effectively.Rectangle, circle, shape such as trapezoidal can be adopted in the cross section of seal 3 and locating part 4.Locating part 4 is made by incompressible metal material, such as the round steel of φ 2～φ 16 or square steel etc.Seal 3 is to be made by the material of transformer oil resistant, as oil resistant rubber, cork-rubber or other compressible high molecular oil-proof material etc.The locating part 4 and the seal 3 of present embodiment can separate, the quantity of locating part 4 be one or two or more than two, it is placed on the one or both sides of seal 3.Certainly locating part 4 also can be combined into an integral body with seal 3, as locating part 4 being coated in the seal 3.
Present embodiment can be used to make calutrons such as oil-filled transformer, reactor.
