Description
Technical field
The present invention relates to the processing and fabricating of mutual inductor more particularly to a kind of manufacture crafts 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 manufacture craft of existing rectangle amorphous transformer core be directly in a rectangular mould carry out around
Line.The advantages of this winding mode is one-pass molding, more convenient；The disadvantage is that the coiling rectangular shaped core meeting directly in rectangular mould
So that magnetic core is tight around that must compare at four right-angle turnings, i.e., rolling density is big, and magnetic core is more loose around obtaining in the middle part of length-width direction, that is, rolls up
It is small around density, cause entire magnetic core elastic different.
Summary of the invention
In view of the above-mentioned problems, the present invention provides a kind of production works of rectangle amorphous transformer core different from the past
Skill.
The present invention protects a kind of manufacture craft of rectangle amorphous transformer core, and rectangular shaped core is by round magnetic core working process
It forms, specifically includes following steps,
Step 1：The inside/outside diameter size of the rectangular shaped core made as needed calculates the size of required round magnetic core mold；
Step 2：Amorphous band is wound on round magnetic core mold, round magnetic core is formed；
Step 3：Round magnetic core is made into rectangular shaped core by shaping mould；
Step 4：By rectangular shaped core together with shaping mould, it is put into heat-treatment furnace and is heat-treated by heat treatment process；
Step 5：Shaping mould is removed, rectangular shaped core after molding is obtained；
Step 6：Rectangular shaped core after molding is fully immersed in the glue that A, B glue and alcohol are formulated by a certain percentage,
Glue is allowed to be fully infiltrated among every a piece of band；
Step 7：Rectangular shaped core is taken out, shaping mould is installed again, solution extra in band is squeezed out；
Step 8：By rectangular shaped core together with shaping mould, it is put into baking oven drying, solidification, sizing；
Step 9：After cooling, shaping mould is removed.
Further, the shaping mould is mainly made of internal core model and external pressing mold；The internal core model is by rectangle
Three pieces of left, center, right submodule composition made of the linear cutter of iron block longitudinal direction, the rectangle iron block perimeter and perimeter in round magnetic core
Equal, height is consistent with round magnetic core height；Shaping step includes：
Step 3.1：Left and right two pieces of submodules are put into the inner ring of round magnetic core, form upward wedge between left and right two pieces of submodules
Mouthful；
Step 3.2：Intermediate submodule is put into wedge mouth, the upper plane of intermediate submodule is tapped with nylon hammer, it is made to wedge left and right two
Between block 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 3.3：External pressing mold is installed, the periphery of magnetic core is also made by rectangle by external pressure.
Further, in the step 4, heat treatment temperature is 550 °；In the step 6, the technique of A, B glue and alcohol is matched
Than being 1：3：10.
The present invention also protects the rectangle mutual inductor manufacture craft using above method production transformer core.
Having the beneficial effect that in the present invention：Solve bring magnetic core size in traditional rectangular shaped core production it is difficult to control,
The problems such as solidification is not thorough with wound core of magnetic around Density inhomogeneity, also accomplishes one in the manufacturing process of entire rectangle amorphous mutual inductor
Mould is dual-purpose, can improve yield but also improve product quality, can also efficiently control the die cost in process；By this
The rectangle mutual inductor for inventing production, with linear precision is good, induction sensitivity is high, anti-overload ability is strong, continues working after molding
The features such as temperature rise is low, good appearance, small in size, easy for installation, current error≤5%, light-weight, totally-enclosed, high insulation.
