Embodiment
With preferred embodiment, the utility model is described in further detail by reference to the accompanying drawings now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present utility model are described in a schematic way, and therefore it only shows the formation relevant with the utility model.
As Figure 1-3, a kind of solve amorphous alloy transformer Short Circuit withstand problem from clamp structure; Comprise A, B, C three-phase coil of horizontal arrangement; Wherein A phase coil 1 adjacent with B phase coil 2 near, B phase coil 2 adjacent with C phase coil 3 near; In Fig. 1, A, B, C three-phase coil comprises the high-tension coil being positioned at outside and the low-voltage coil being positioned at inner side respectively; Low-voltage coil is the paper tinsel coiling of Copper Foil coiling, is sandwich construction; Thermosetting binder insulating material is utilized to make low-voltage coil solidify and become the binding clip that has certain mechanical strength between layers of foil and layers of foil.
Unite by PET strip 5 after A phase coil 1 and the adjacent of B phase coil 2 are placed U-shaped insulating board 4 and tie up; As shown in Figure 5, the low-voltage coil of adjacent two-phase is by PET strip 5 colligation mutually; And the low-voltage coil of adjacent two-phase forms clamping plate to being clamped by the high-tension coil of adjacent two-phase and fixing; After colligation, high-tension coil 7-1 and low-voltage coil 7-2 is fixed as one.High and low pressure intercoil insulation 8 is provided with between high-tension coil 7-1 and low-voltage coil 7-2; In Fig. 5, high-tension coil 7-1 and low-voltage coil 7-2 is non-fully section.
Shown in Fig. 3 is when short-circuit force is larger, and A phase coil 1 is respectively arranged with insulating epoxy plate 6 with the outside of C phase coil 3; Insulating epoxy plate 6 and the low-voltage coil 7-2 of this phase form clamping plate to and by binding strap colligation, and clamp and fix the high-tension coil 7-1 of this phase, its structure is as shown in Figure 4.Certainly, when the product short-circuit force for low capacity is less, the clamping plate outside A, C phase coil can be cancelled, and only strengthen with bandage.In Fig. 4, high-tension coil 7-1 and low-voltage coil 7-2 is also non-fully section.
The utility model all has extraordinary effect from anti-width to the angle of short-circuit force with from anti-axial short-circuit force angle:
1, from anti-width to the angle of short-circuit force;
Traditional anti-width to short circuit measure, or leans on the intensity of transformer coil conductor itself, or increases the passive supports such as supplementary structure (as insulating cylinder, stay);
And the utility model utilizes low voltage foil winding coil to become one " structural clamping plate " by layer insulation is settable cementitious; Due to low-voltage coil side in coil, therefore the low-voltage coil of internal side diameter solidified forming can be utilized as clamping plate, initiatively grip coil, prevent the width of coil to distortion and displacement; And low voltage foil winding coil is cured as one, makes low-voltage coil be an electrical installation, is also structure clamping plate simultaneously, thus eliminating the epoxy cylinder that original structure requires, and intensity is high more than epoxy cylinder;
A, C phase coil is in the rectangle straight portion in outside, pastes and to increase by one piece outside high pressure with the contour high-strength insulating plate of coil as clamping plate.This cleat insulator and corresponding mutually the low-voltage coil of solidified forming forms a pair " clamping plate to ", initiatively grip coil, prevent the width of coil to distortion and be shifted; " clamping plate to " structure initiatively clamps high-voltage coil and low-voltage coil, prevents transformer coil to be out of shape, displacement and damage.
The colligation of clamping plate and insulating part have employed general PET strip, i.e. polyester binding strap; Intensity is high, low price, construction technology are good, can make between out-phase low-voltage coil easily or low-voltage coil and epoxy clamping plate form firmly " clamping plate-clamping plate " structure, firmly secures the high-tension coil and low-voltage coil that produce short circuit.Certainly, also alternative PET strip can be carried out with other material; And the improving bud grafting of PET strip can use the packing manner of common baling press to complete.
2, from the angle of anti-axial short-circuit force;
PET strip is adopted the high-tension coil of transformer and low-voltage coil to be combined into a firmly entirety, dependence " clamping plate-clamping plate " structure fix coil width to while, by low-voltage coil and clamping plate, colligation drawstring limits the axially displaced of high-tension coil and low-voltage coil simultaneously, therefore can cancel transformer axial compacting structure, simplified structure also reduces cost of manufacture.
Whole coil banding mode is simple, convenient, therefore, utilizes the utility model patent, not only increase the Short Circuit withstand problem of amorphous alloy transformer, and structure is simple, construction aspect, significantly reduces transformer cost of manufacture, has extensive, huge social performance.
The just embodiment of the present utility model described in above specification, various illustrating is not construed as limiting flesh and blood of the present utility model, person of an ordinary skill in the technical field after having read specification can to before described embodiment make an amendment or be out of shape, and do not deviate from essence and the scope of utility model.
