Abstract
The utility model relates to a structure for pressing and fixing reactor-body magnetic shields. A magnetic shield is placed on an upper pressing plate. The structure also comprises a bent plate and a pressing nail. The pressing nail penetrates through a clamping piece, with the lower end being abutting against the magnetic shield and with the upper end being through a limit hole of the bent plate. The bent plate is tightly pressed on the clamping piece via a bolt. The bent plate has parallel surfaces and is in the bending form with double right angles, wherein one parallel surface is provided with the limit hole and the other parallel surface is provided with a bolt hole. The top of the pressing nail and the limit hole have an identical shape and are matched in terms of size. The structure of the utility model can effectively restrain the pressing nail from becoming loose, guaranteeing the pressing effect and reducing vibration.
Description
Technical field
The utility model relates to reactor manufacturing technology field, and the magnetic screen of a kind of specifically reactor device body is fixed structure.
Background technology
Reactor is widely used in limiting short-circuit current, reactive power compensation, phase shift etc. as the high voltage induction element in electric power system.Produce local overheating in the folder in order to prevent that leakage flux from entering, all leakage fluxs are all circulated along the passage of defined, need be in yoke folder place placement magnetic screen up and down, make itself and iron yoke form an omnibearing leakage flux passage, stopped leakage flux and entered in the folder, eliminated the local overheating phenomenon that causes by leakage flux and greatly reduce loss.Because present reactor adopts wide yoke structure, promptly iron yoke area coverage increases, and it is less that coil is exposed at the outer area of iron yoke, brings the evenly problem of compactor body of nail of pressing.Device body compressing method is changed at present, and original pressure pin structure is inapplicable because of no operating space.
The utility model content
At the inapplicable situation of original compressing structure, the technical problems to be solved in the utility model provides the wide yoke structure of a kind of suitable reactor, and can effectively compress, and reduces the reactor device body magnetic screen compressing structure of vibration.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
The utility model reactor device body magnetic screen compressing structure, magnetic screen is positioned on the top board, and also have bent plate and press nail, after the pressure nail places folder, bottom and magnetic screen butt, the upper end is placed through in the spacing hole of bent plate, and bent plate is pressed on the folder through bolt.
Described bent plate is two sections right angle bending forms with parallel surface, and one of them parallel surface is provided with spacing hole, and another parallel surface is provided with bolt hole.
Described pressure screw top portion shape is identical with the spacing hole shape, the size coupling.
Between pressure nail lower end and magnetic screen, cross-over block is set.
The utlity model has following beneficial effect and advantage:
1. the utility model can effectively limit and press nail loosening, guarantees to compress effect, reduces vibration.
Description of drawings
Fig. 1 is the utility model structural representation.
Wherein, 1 is bolt; 2 is spacing bent plate; 3 for pressing nail; 4 is folder; 5 is cross-over block; 6 are magnetic screen.
Embodiment
As shown in Figure 1, for the magnetic screen of clarity device body be fixed in the structural configuration of each several part, the miscellaneous part of reactor is illustrated with double dot dash line.The utility model reactor device body magnetic screen compressing structure comprises spacing bent plate 2 and presses nail 3, magnetic screen 6 is installed on the top board 7, after pressing nail 3 to place folder 4, bottom and cross-over block 5 butts that are put in the magnetic screen 6, the upper end is placed through in the spacing hole of spacing bent plate 2, and spacing bent plate 2 is pressed on the folder 4 through bolt 1.
