Brief description of the drawings
In order to illustrate more clearly about the embodiment of the present invention or technical scheme of the prior art, below will be to embodiment or existing There is the accompanying drawing used required in technology description to be briefly described, it should be apparent that, drawings in the following description are only this The embodiment of invention, for those of ordinary skill in the art, on the premise of not paying creative work, can also basis The accompanying drawing of offer obtains other accompanying drawings.
Fig. 1 is the structural representation of the setting device of Transformer Winding axial pressing force of the embodiment of the present invention.
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete Site preparation is described, it is clear that described embodiment is only a part of embodiment of the invention, rather than whole embodiments.It is based on Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under the premise of creative work is not made Embodiment, belongs to the scope of protection of the invention.
Fig. 1, the setting device for the Transformer Winding axial pressing force that the present embodiment is provided are refer to, including is oppositely arranged Fixation on disk 1 and pressing plate lower wall 2, and be juxtaposed on fixed upper two setting screw rods 3 between disk 1 and pressing plate lower wall 2; Pressing plate lower wall 2 is perpendicular to the axis direction of Transformer Winding, and disk 1 is fixed under the surface of Transformer Winding, pressing plate in fixation Disk 2 at the top of Transformer Winding with offseting;The two ends of setting screw rod 3 are connected upper disk 1 and pressing plate lower wall 2 respectively, set spiral shell The adjustable length of bar 3 so that relative to fixed upper disk 1 relative displacement can occur for pressing plate lower wall 2.
Pressing plate lower wall 2 is down moved produces axial pressing force, axial pressing force size and its institute to Transformer Winding extruding It is subjected to displacement and is proportionate.Determined by many experiments, can obtain the logical operation relation between both, it would be desirable to setting Axial pressing force numerical value substitutes into conversion, that is, calculates the precise displacement that pressing plate lower wall 2 is moved downward, easy to operate, and setting is accurate.
Further, in order to further enhance the convenience of setting device of the present invention operationally, and setting is improved Accuracy, overcomes human error, and the present embodiment is also provided with pressure sensor 5 and long in fixation between disk 1 and pressing plate lower wall 2 Spend adjustable secondary setup screw rod 4.Wherein, the wherein one end for the secondary setup screw rod 4 being arranged between two setting screw rods 3 connects Fixed upper disk 1 is connect, the other end points to pressure sensor 5;Pressure sensor 5 is detachably arranged at pressing plate lower wall 2 and positioned at auxiliary Set the underface of screw rod 4.
By adjusting the length of secondary setup screw rod 4 to its end conflict pressure sensor 5 and pressure sensor 5 being applied Pressure, until pressure sensor 5 reaches the pressure value of needs;Then the downward displacement release pressure of regulation pressing plate lower wall 2 is passed The pressure that sensor 5 is applied in is until the numerical value of pressure sensor 5 is reduced to zero, and the axial direction that now pressing plate lower wall 2 applies to winding is pressed Clamp force size sets pressure needed for being.
In order to disperse the pressure applied when the end of secondary setup screw rod 4 is moved downward to pressure sensor 5, further carry The accuracy of the high present apparatus, the present embodiment is provided with disk 6 on pressing plate also between secondary setup screw rod 4 and pressure sensor 5.Pressure The side of disk 6 is fixedly connected with one end of secondary setup screw rod 4 on plate, and opposite side offsets with the pressure sensor 5.
In order that the length direction of screw rod 3 can be set solid with the length change edge of secondary setup screw rod 4 by obtaining disk 6 on pressing plate Surely it is upper to be adjusted back and forth between disk 1 and pressing plate lower wall 2.Disk 6 is provided with multiple through holes passed through for setting screw rod 3 on pressing plate
Further, disk 6 is the plate body in long plate shape on disk 1, pressing plate lower wall 2 and pressing plate in fixation.
Further, it is described to be connected as bolt connection.
It is the structure of setting device and its retouching for annexation of the Transformer Winding axial pressing force of the present embodiment above State, the course of work that one of example application illustrates the setting device of the present embodiment is lifted below:
When being set to the axial pressing force of Transformer Winding, pressure sensor 5 is first put into disk 6 and pressing plate on pressing plate Between lower wall 2;Then, the length of secondary setup screw rod 4 is slowly increased, the registration of pressure sensor 5 is reached the numerical value of needs; Then, while slow equably adjust two setting screw rods 3, pressure is discharged, until the registration of pressure sensor 5 is reduced to zero;Most Afterwards, secondary setup screw rod 4 is unclamped, pressure sensor 5 is taken out, now axis of winding thrust is to be set as required numerical value.
The above embodiments are merely illustrative of the technical solutions of the present invention, rather than its limitations;Although with reference to the foregoing embodiments The present invention is described in detail, it will be understood by those within the art that:It still can be to foregoing each implementation Technical scheme described in example is modified, or carries out equivalent substitution to which part technical characteristic;And these modification or Replace, the essence of appropriate technical solution is departed from the spirit and scope of various embodiments of the present invention technical scheme.
