Description
Technical field
The utility model relates generally to power transformer technical field, more particularly to a kind of transformer enclosed construction.
Background technology
With developing rapidly for social economy, in short supply, the transformer substation construction pair of urban land resource
Space availability ratio proposes higher requirement.Two-piece unit formula concentrates cooling transformer to take full advantage of transformer room
The space of top, there is superior development prospect in transformer substation in city.Two-piece unit formula transformer is due to radiator and oil storage
Cabinet is higher than transformer body, and transformer body can be born than horizontally disposed bigger oil pressure, and therefore, two-piece unit formula is concentrated cold
But the key technology of transformer is solve the transformer sealing problem brought greatly due to difference in height, and fuel tank edge sealing structure can
It is the key of transformer long-term safety operation by property.
Currently used case has two kinds along structure, and one kind is bolt fastening, and one kind is to be welded case entirely along structure.Bolt fastens
In structure, case bears pressure along seal in long-term transition, and leakage of oil problem easily occurs in the later stage.Case is welded along structure raising middle flask entirely
Permanent seal can be born along seal-weld, is not in leakage problems, but the full fuel tank that is welded is carrying out positive pressure test and vacuum
Bolt during experiment due to no fastening limits the deformation on case edge within the specific limits, if not taking spacing measure, fuel tank
Gross distortion can be produced, causes fuel tank to damage.
The content of the invention
It can prevent transformer oil tank edge from deforming in view of the deficienciess of the prior art, the utility model aims to provide one kind
Enclosed construction.
To achieve the above object, the utility model provides following technical scheme：
A kind of transformer enclosed construction, including tank wall, the tank wall, which joins end to end, surrounds tubular, in the top surface of the tank wall
On formed with opening, on the fixed case edge in the top of the tank wall, the case along around the circumferentially disposed of the opening and with it is described
Tank wall is vertical, and in the case along square keyway is above opened up, lid sets case lid over said opening, is set in the bottom of the case lid
There is seal bond, the sealing bond energy is snapped fit onto in the keyway；
Also include mould assembling frock, the mould assembling frock includes fixed plate, connecting plate and jack, and the fixed plate passes through spiral shell
Nail is fixed on outside reference, and the connecting plate is fixed in the fixed plate, described in the connecting plate formed with guide rail
Jack one end is slidably connected on the guide rail, and the other end acts against the edge of the case lid.
As improvement of the present utility model, the connecting plate includes transverse slat and riser, described transverse slat one end and the fixation
Plate is connected, and the other end links into an integrated entity with the riser, and the transverse slat is vertical with the riser, and the guide rail is opened in described perpendicular
On plate.
As further improvement of the utility model, in the case along seal groove is above further opened with, in the case lid bottom
Seal is provided with, when the case lid lid is set over said opening, the seal can be filled into the seal groove.
Further improved as of the present utility model, the transverse slat is connected with the fixed plate by the screw.
As it is of the present utility model preferably, the edge of the case lid and the case between formed with weld seam.
Compared with prior art, the utility model has the advantage of：This enclosed construction sealed reliable, and can prevent from filling
Deformed with process raising middle flask along being pressurized.
Brief description of the drawings
Fig. 1 is the schematic diagram of transformer enclosed construction in the utility model embodiment；
Fig. 2 is Fig. 1 partial structural diagram.
Embodiment
The embodiment of transformer enclosed construction in the utility model is described further referring to the drawings.
As shown in drawings, the present embodiment is a kind of transformer enclosed construction, including tank wall 1, and the tank wall, which joins end to end, to be enclosed
Into tubular, the bottom of tubular tank wall is sealed by the bottom plate of circle, formed with opening on the top surface of tubular tank wall, on the top of tank wall
The fixed case in portion is along 2, and case edge is around the circumferentially disposed and vertical with tank wall of opening, and case edge is extended by outward opening, in case
Square keyway 21 is opened up on edge, lid sets case lid 3 in opening, and seal bond 31 is provided with the bottom of case lid, seals bond energy card
It is connected in keyway, so as to which along snapping together, case lid and case are formed into the sealing to transformer tank.Due to during fastening,
Case lid needs downwards firmly, and this results in case along being possible to deform downwards under the pressure effect of case lid, in order to prevent this
The generation of one phenomenon, mould assembling frock being also set up outside tank wall, mould assembling frock includes fixed plate 4, connecting plate 5 and jack 6, Gu
Fixed board is fixed on outside reference by screw 7（Metope or other vertical fixtures）On, connecting plate includes the He of transverse slat 51
Riser 52, is provided with some screwed holes on transverse slat, and foregoing screw can be subsequently inserted into also cross screwed hole and fixed plate
In metope, the fixation of three is realized with this, due to being provided with multiple screwed holes on transverse slat, therefore can be by being inserted not to screw
The relative position between fixed plate and transverse slat is adjusted with the selection of screwed hole.One end of transverse slat is connected with fixed plate, the other end
Linked into an integrated entity with riser, and transverse slat is vertical with riser, and guide rail 8 is offered on riser, and jack one end is slidably connected at
On guide rail, the other end acts against the edge of case lid.When covering case lid, first case lid is clamped by two mould assembling frocks in advance, with
Mould assembling work is fixed on metope afterwards so that a supporting role is played in the bottom that fixed plate withstands on case edge, then causes very heavy
Top is moved down along guide rail, and case lid is covered in case along upper, thus it can be prevented that case along downward deformation occurs in installation process.
In order to ensure sealing, in case along seal groove 22 is above further opened with, case lid bottom is provided with seal 32, works as case
When lid lid is set over said opening, seal can be filled into seal groove.In addition, the shape between the edge of case lid and case edge
Into there is weld seam, welded by filling waterproof solder in weld seam so that play the effect of dual-seal in case edge.
It is described above to make preferred embodiment of the present utility model, do not depart from for the person of ordinary skill of the art
On the premise of the utility model principle, some variations and modifications can also be made, these also should be regarded as protection of the present utility model
Scope.
