Specific implementation mode
Present invention will now be described in further detail with reference to the embodiments and the accompanying drawings, but embodiments of the present invention are unlimited
In this.
Embodiment
As shown in Figure 1, dry-type transformer body structure of the present invention, is cuboid or square, including 12 support frames
Frame, the plank for forming six faces of babinet are correspondingly fixed in braced frame.Wherein, left side, right side, top end face and bottom end
This four faces of face are telescopic, left side and top end face, left side and bottom face, right side and top end face, right side and bottom
The braced frame that end face shares is all made of telescopic structure, and the plank in this four faces stretches with the flexible of braced frame,
So that body structure volume-tunable section on the whole, convenient for after the places such as factory assemble, transporting transformer actual use
It is installed in place.State after babinet is shunk is as shown in Figure 2.
Now by taking left side as an example, detailed description be how to realize it is flexible.Left side includes mainly left end plank 53, centre
Plank 51 and right end plank 52, left end plank 53 are connect in vertical direction with fixed support frame frame 54, and right end plank 52 is vertical
Direction is connect with fixed support frame frame 55.The upper and lower braced frame 1 of left side is telescopic, and stretching structure is identical, is such as schemed
Shown in 3, including left end shrinks frame 13, middle shrinkage frame 11 and right end and shrinks frame 12, and left end shrinks frame 13 and right end
The outer diameter for shrinking frame 12 is slightly less than the internal diameter of middle shrinkage frame 11, and left end shrinks frame 13 and right end shrinks frame 12 and distinguishes
It is slidably connected with middle shrinkage frame 11, is fixed by lock 2 when stopping sliding.It is stretched when retractable supports frame 1 is in
It is left to shrink frame 13, the right both ends shunk frame 12 and be respectively exposed to middle shrinkage frame 11 when state, as shown in Figure 3；When can
When retractable support frame 1 is in contraction state, left contraction frame 13, right contraction frame 12 are nested in middle shrinkage frame 11
It is interior, as shown in Figure 4.Lock 2 is respectively equipped on left contraction frame 13, right contraction frame 12, lock 2 is with left and right contraction frame one
Play sliding.The both ends of retractable supports frame 1 are connect with Corner Link 14 respectively；Corner Link 14 is set there are three connecting pin
Mouthfuls 141, to which three faces on the same vertex of body structure are fixedly connected, such as by left side, front end face and bottom face
It is fixedly connected.
With reference to figure 5, on the adjacent two sides of fixed support frame frame and retractable supports frame of the present invention, respectively it is equipped with and uses
In the slit 15,16 of fixed plate, consequently facilitating the plank in six faces of static housing structure；By taking left side as an example, slit 15 is set
It sets on left contraction frame 13, right contraction frame 12, slit 16 is arranged on middle shrinkage frame 11.In the preferred scheme,
In order to facilitate the stretching and contraction of body structure, slit 15,16 is embedded in fixed support frame frame or scalable branch it is not recommended that selecting
The form of support frame frame, but it is preferred that extended outward to form from fixed support frame frame or retractable supports frame facet, slit 15,
16 have certain height, such as can be 2/3 or more of fixed support frame frame or retractable supports frame facet width, most
It is no more than fixed support frame frame or retractable supports frame facet width when high.
From structure shown in Fig. 5 it is found that retractable supports frame is other than being equipped with slit 15,16, in middle shrinkage frame 11
On be additionally provided with for it is left contraction frame 13, it is right shrink frame 12 slide sliding slot 17, and for lock 2 sliding sliding slots 18；Slit
15 are embedded into left contraction frame 13, the right sliding slot 17 for shrinking the sliding of frame 12；Lock 2 is fixed on left contraction frame 13 or the right side
Shrink on frame 12, but for locking, the poke rod of opening lock catch 2 pass through sliding slot 18 to expose to the side of middle shrinkage frame 11
Face.
Transformer generally starts by special temperature control system or closes the wind turbine mounted on bottom to control temperature
Degree.As shown in Figure 1, 2, the present invention adds supporting rack in the back of the transformer temperature control system positioned at body structure front end face
Structure 3 optimizes heat dissipation effect to fully consider the flow direction of wind-force；Sheet metal 4 is added also on the door handle of front end face, with
Increase support degree.In order to further strengthen heat dissipation effect, the left and right side of body structure and the plank of top end face are constituted, is adopted
The network made of aluminium.
In addition, transformer-cabinet should have certain structural strength, and be not in rock and loose phenomenon after assembling, one
The people of a 80kg stands on the frame of babinet, and shell is answered indeformable.For six faces of babinet intermediate region, then without so high
Intensity requirement.The degree of protection of babinet includes IP20, IP30, IP40 etc. several, also there is the design requirement of IP43 sometimes.IP20 refers to
The foreign matter no more than 12.5mm can be protected to enter, IP30, which refers to, can protect the foreign matter no more than 2.5mm to enter, and IP40 refers to can be with
Foreign matter of the protection no more than 1mm enters.Since transformer is to belong to high-tension electricity equipment, all supplementary materials all should
With anti-flammability.
The above embodiment is a preferred embodiment of the present invention, but embodiments of the present invention are not by above-described embodiment
Limitation, it is other it is any without departing from the spirit and principles of the present invention made by changes, modifications, substitutions, combinations, simplifications,
Equivalent substitute mode is should be, is included within the scope of the present invention.
