Description
Technical field
The present invention relates to the processing and fabricating of mutual inductor more particularly to a kind of shaping process of rectangle amorphous transformer core.
Background technique
The electromagnetic current transducer (abbreviation current transformer) being widely used in electric system, working principle and transformation
Device is similar, and only transformer transformation is voltage, and current transformer transformation is electric current.In power generation, power transformation, transmission of electricity, distribution
With in electric line, electric current is very greatly different from several peaces to several Wan An.It is mutual using electric current to need convenient for measurement, protection and control
Sensor is converted to the electric current of unified size；In addition the voltage on route is generally relatively high, and directly measurement is breakneck, electricity
Current transformer just plays the role of current transformation and electrical isolation.
General mutual inductor is mostly circle, but as scientific and technological level constantly improves, mutual inductor application field is constantly expanded,
Rectangular current mutual inductor is as detecting element, it has also become one of the component of most critical, major function are in electric leakage monitoring system
Detection is by the residual current (earth-fault currents such as electric shock, electric leakage) of the main current loop of mutual inductor center hole, and by main electricity
The residual current for flowing back to road is transformed into the output electric current of secondary winding.Rectangle punching residual current transformer is mainly used for busbar
In installation environment, it can also be used in cable installation environment.Rectangle mutual inductor another characteristic is that, structure be in rectangle, work
Window is bigger, coiling of being more convenient for, and also more conducively rectangle mutual inductor develops to miniaturization.
However, the shaping process of existing rectangle amorphous transformer core is by amorphous band directly in a rectangular mould
Upper carry out coiling.The advantages of this winding method is one-pass molding, more convenient；The disadvantage is that the coiling square directly in rectangular mould
Shape magnetic core can make at four right-angle turnings magnetic core tight around that must compare, i.e., rolling density is big, and magnetic core is around must compare in the middle part of length-width direction
More loose, i.e., rolling density is small, causes entire magnetic core elastic different.
Summary of the invention
In view of the above-mentioned problems, the present invention provides a kind of shaping works of rectangle amorphous transformer core different from the past
Skill.
Round magnetic core is made into rectangular shaped core by shaping mould by a kind of shaping process of rectangle amorphous transformer core,
The shaping mould is mainly made of internal core model and external pressing mold；The internal core model is by rectangle iron block vertical line cutting processing
Made of left, center, right three pieces of submodules composition, the rectangle iron block perimeter grows equal, height and circle with round magnetic core inner circumferential
Magnetic core height is consistent；Shaping step includes,
Step 1: left and right two pieces of submodules being put into the inner ring of round magnetic core, form upward wedge between left and right two pieces of submodules
Mouthful；
Step 2: intermediate submodule being put into wedge mouth, the upper plane of intermediate submodule is tapped with nylon hammer, it is made to wedge left and right two pieces
Between submodule, until the end face of three pieces of submodules is concordant, so far, is enclosed in magnetic core and be made into rectangle；
Step 3: external pressing mold being installed, the periphery of magnetic core is also made by rectangle by external pressure.
Further, the external pressing mold includes a rectangular frame and is installed on the rectangular frame four edges frame
Miniature guide rod cylinder, the rectangular frame inside dimension are greater than the rectangular shaped core outside dimension.
Further, for four miniature guide rod cylinders by its movement of two solenoid valve controls, each solenoid valve control is opposite
Two miniature guide rod cylinders.
Having the beneficial effect that in the present invention can will be shaped to rectangular shaped core around the round magnetic core made, avoid directly
In rectangular shaped core mold in coiling caused by the non-uniform problem of rolling density.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of internal core model；
Fig. 2 is the structural schematic diagram of external pressing mold.
Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.
Round magnetic core is made into rectangular shaped core by shaping mould by a kind of shaping process of rectangle amorphous transformer core,
The shaping mould is mainly made of internal core model and external pressing mold；The internal core model is by rectangle iron block vertical line cutting processing
Made of left, center, right three pieces of submodules composition, as shown in Figure 1, the rectangle iron block perimeter grown with round magnetic core inner circumferential it is equal,
Height is consistent with round magnetic core height；Shaping step includes,
Step 1: two pieces of left A1, right A2 submodules are put into the inner ring of round magnetic core, formed between two pieces of left A1, right A2 submodules to
On wedge mouth；
Step 2: intermediate submodule A3 is put into wedge mouth, the upper plane of intermediate submodule A3 is tapped with nylon hammer, make its wedge left A1,
Between two pieces of submodules of right A2, until the end face of tri- pieces of submodules of A1, A2, A3 is concordant, so far, is enclosed in magnetic core and be made into rectangle；
Step 3: external pressing mold being installed, the periphery of magnetic core is also made by rectangle by external pressure.
The external pressing mold includes a rectangular frame 1 and the miniature guide rod cylinder for being installed on the rectangular frame four edges
2, as shown in Fig. 2, the rectangular frame inside dimension is greater than the rectangular shaped core outside dimension.
By its movement of two solenoid valve controls, each solenoid valve control opposite two miniature to lead four miniature guide rod cylinders
Bar cylinder, two solenoid valves can be controlled by two buttons, can also be controlled by a button.
External pressing mold is lightly covered in magnetic core periphery, control button is pressed, four miniature guide rod cylinders slowly push away simultaneously
To the four edges of magnetic core periphery, (or a pair of opposite miniature guide rod cylinder is first squeezed, the opposite miniature guide rod of another pair
Squeezed after cylinder), and pressure is maintained, make magnetic core periphery be made into rectangle by the pressure of cylinder in this way.
The foregoing is only a preferred embodiment of the present invention, but scope of protection of the present invention is not limited thereto,
Anyone skilled in the art in the technical scope disclosed by the present invention, according to the technique and scheme of the present invention and its
Inventive concept is subject to equivalent substitution or change, should be covered by the protection scope of the present invention.
