Specific embodiment
With reference to embodiment and accompanying drawing, the present invention is described in further detail, but embodiments of the present invention are not limited
In this.
Embodiment
As shown in figure 1, dry-type transformer body structure of the present invention, is cuboid or square, including 12 carriages
Frame, the sheet material for forming six faces of casing are correspondingly fixed in support frame.Wherein, left surface, right flank, top end face and bottom
This four faces of face are telescopic, left surface and top end face, left surface and bottom face, right flank and top end face, right flank and bottom
The shared support frame of end face adopts the sheet material in telescopic structure, this four faces to stretch with the flexible of support frame,
So that body structure volume-tunable section on the whole, is easy to after the places such as factory assemble, transport is actually used to transformer
Installed in place.State after casing shrinks is as shown in Figure 2.
Now by taking left surface as an example, detailed description be how to realize flexible.Left surface mainly includes left end sheet material 53, centre
Sheet material 51 and right-hand member sheet material 52, left end sheet material 53 are connected with fixed support frame frame 54 in vertical direction, and right-hand member sheet material 52 is vertical
Direction is connected with fixed support frame frame 55.The upper and lower support frame 1 of left surface is telescopic, and its stretching structure is identical, such as schemes
Shown in 3, framework 13, middle shrinkage framework 11 and right-hand member being shunk including left end and shrinking framework 12, left end shrinks framework 13 and right-hand member
The external diameter for shrinking framework 12 is slightly less than the internal diameter of middle shrinkage framework 11, and left end shrinks framework 13 and right-hand member shrinks framework 12 and distinguishes
It is slidably connected with middle shrinkage framework 11, is fixed by lock 2 when stopping sliding.When retractable supports framework 1 is in stretching
During state, left contraction framework 13, right contraction framework 12 are respectively exposed to the two ends of middle shrinkage framework 11, as shown in Figure 3；When can
When retractable support framework 1 is in contraction state, left contraction framework 13, right contraction framework 12 are nested in middle shrinkage framework 11
Interior, as shown in Figure 4.Lock 2 is respectively equipped with left contraction framework 13, right contraction framework 12, and lock 2 is with left and right contraction framework one
Rise and slide.The two ends of retractable supports framework 1 are connected with Corner Link 14 respectively；Corner Link 14 is provided with three connection ends
Mouth 141, so as to three faces by same for body structure summit are fixedly connected, such as by left surface, front end face and bottom face
It is fixedly connected.
On adjacent two sides with reference to Fig. 5, fixed support frame frame of the present invention and retractable supports framework, use is respectively provided with
In the slit 15,16 of fixed plate, consequently facilitating the sheet material in six faces of static housing structure；By taking left surface as an example, slit 15 sets
Put on left contraction framework 13, right contraction framework 12, slit 16 is arranged on middle shrinkage framework 11.In preferred scheme,
The stretching and contraction of body structure for convenience, slit 15,16 are embedded in fixed support frame frame or scalable it is not recommended that selecting
The form of support frame frame, but it is preferred that stretch out to be formed from fixed support frame frame or retractable supports frame facet, slit 15,
16 have certain height, for example, can be more than the 2/3 of fixed support frame frame or retractable supports frame facet width, most
Less than fixed support frame frame or retractable supports frame facet width when high.
Knowable to structure shown in Fig. 5, retractable supports framework in addition to being provided with slit 15,16, in middle shrinkage framework 11
On be additionally provided with for left shrink framework 13, right shrink framework 12 slide chute 17, and for lock 2 slide chutes 18；Slit
During 15 are embedded into for left contraction framework 13, the right chute 17 for shrinking the slip of framework 12；Lock 2 is fixed on left contraction framework 13 or the right side
Shrink on framework 12, but for locking, the poke rod of opening lock catch 2 expose to the side of middle shrinkage framework 11 through chute 18
Face.
Transformer typically starts by special temperature control system or cuts out blower fan installed in bottom to control temperature
Degree.As shown in Figure 1, 2, the present invention adds bracing frame in the back of the transformer temperature control system for being located at body structure front end face
Structure 3, to take into full account the flow direction of wind-force, optimizes radiating effect；Add sheet metal 4 also on the door handle of front end face, with
Increase support degree.In order to further strengthen radiating effect, the left and right side of body structure and the sheet material of top end face is constituted, is adopted
The network that is made with aluminium.
Additionally, transformer-cabinet should have certain structural strength, and be not in rock and loosen phenomenon after assembling, one
The people of individual 80kg is stood on the frame of casing, and shell should be indeformable.For six face zone lines of casing, then so not high
Intensity requirement.The degree of protection of casing includes that IP20, IP30, IP40 etc. are several, also has sometimes the design requirement of IP43.IP20 refers to
The foreign matter of no more than 12.5mm can be protected to enter, IP30 refers to that the foreign matter that can protect no more than 2.5mm is entered, IP40 refers to can be with
Protection is not more than the foreign matter of 1mm and enters.As transformer is belonging to high-tension electricity equipment, therefore its all supplementary material all should
There is anti-flammability.
Above-described embodiment is the present invention preferably embodiment, but embodiments of the present invention are not by above-described embodiment
Limit, other any Spirit Essences without departing from the present invention and the change, modification, replacement that is made under principle, combine, simplification,
Equivalent substitute mode is should be, is included within protection scope of the present invention.
