Description

A kind of clamping piece magnetic shielding structure of top combined type bottom monoblock type
Technical field
A kind of clamping piece magnetic shielding structure of top combined type bottom monoblock type is the utility model is related to, is related to power transformer Equipment technical field, more specifically to a kind of special clamping piece magnetic shielding structure.
Background technology
Folder magnetic screen is widely applied to power transformer, and the folder magnetic screen up-down structure of usual structure is consistent, For two-part structure.Many difficulties in manufacture be present in original clamping piece magnetic shielding structure.Have the disadvantage that:
1st, monolithic length is long causes to have difficulties during manufacture.
2nd, there is breakpoint among bottom two-part structure, reduce Magnetic Shielding Effectiveness.
3rd, two-part structure in top can not adapt to the highly inconsistent situation of each phase coil.
4th, one section long in top two-part structure installation is more difficult.
5th, magnetic screen fixed form uses insulating part stretching structure, some problems be present.
6th, used between two sections of magnetic screens without latitude band colligation, difference in height problem can not be adapted to.
The content of the invention
The purpose of this utility model is to provide a kind of clamping piece magnetic shielding structure of top combined type bottom monoblock type, structure Simple operations are good.
The utility model adopts the following technical scheme that to achieve these goals:
A kind of clamping piece magnetic shielding structure of top combined type bottom monoblock type, three sections of groups are used on the top of power transformer Box-like magnet shielding structure;
Monoblock type magnet shielding structure is used in the bottom of power transformer;
The three segments combined magnet shielding structure is fixed on fagging by nail pressing;
Conductor grip clamping structure is provided at both ends with three segments combined magnet shielding structures.
Further, described three segments combined magnet shielding structures by three magnet shielding structure units length direction splice or Person pastes composition.
Further, the fagging is insulation fagging.
The beneficial effects of the utility model:
Magnetic screen length direction of the present utility model can disconnect shearing, then splice, paste.
Substructure of the present utility model uses a monoblock type magnetic screen.Top of the present utility model is using three sections of combinations Formula magnetic screen.Magnetic screen of the present utility model increases nail pressing on the basis of being fixed on fagging stretching.It has operation simple in construction The advantages of property is good.
Large-capacity power transformer can greatly reduce the spuious of transformer using folder magnetic screen of the present utility model Loss, so as to come reach reduce transformer manufacturing cost purpose.
Brief description of the drawings
Fig. 1 is the schematic diagram of magnet shielding structure of the present utility model;
Fig. 2 is structural representation of the present utility model;
Fig. 3 is depression angle schematic diagram of the present utility model.
Embodiment
1,2,3 pair of the utility model is described in detail below in conjunction with the accompanying drawings:
A kind of clamping piece magnetic shielding structure of top combined type bottom monoblock type, three sections of groups are used on the top of power transformer Box-like magnet shielding structure 1;
Monoblock type magnet shielding structure 2 is used in the bottom of power transformer;
The three segments combined magnet shielding structure 1 is fixed on fagging 4 by nail pressing 3;
Conductor grip clamping structure 5 is provided at both ends with three segments combined magnet shielding structures 1.
The fagging 4 is insulation fagging.
