Description
Technical field
The present invention relates to high frequency transformer field more particularly to a kind of lossless disassembling methods of high frequency transformer, further relate to reality
The dismantling circuit of the existing disassembling method.
Background technique
Due to current power supply adaptor, processing method used by the high frequency transformer in charger and LED driving is all
It is impregnated with all Li Shui, pin deck black glue is fixed in magnetic core, is then formed using high-temperature baking, can be to high frequency transformer in dismantling
The problem of magnetic core damages or difficult dismantling, this is a headache for engineers and technicians.
The prior art generally can all disassemble magnetic core heating using heat gun, and another way is with chemistry such as Tianna solutions
Solvent soaking dissolves varnish, loses cementation, dismantle magnetic core.The insulating tape and enameled wire of transformer can be damaged in this way.
This mode is bad but again without better solution.
Summary of the invention
To solve the problems of the prior art, the present invention provides a kind of lossless disassembling method of high frequency transformer, also provides one
Kind realizes the dismantling circuit of the disassembling method.
The lossless disassembling method of high frequency transformer of the present invention includes the following steps:
S1: the insulating tape place to go on magnetic core of transformer, magnetic core is exposed；
S2: it after load and magnetic core series connection, is powered to magnetic core both ends；
S3: magnetic core persistent fever for a period of time, until varnish melt；
S4: magnetic core is dismantled in power-off.
The present invention is further improved, and in step s 2, the load is osram lamp, and the power of the osram lamp is
100W。
The present invention was further improved, using 50~120V adjustable ac source energization 1-2 minutes.
The present invention also provides a kind of dismantling circuits for realizing the disassembling method, including adjustable ac source, load, exchange
Power meter, alternating-current switch SW1 and 2 conduct pieces for being respectively used to connection magnetic core both ends and being powered for magnetic core, wherein the exchange
Power meter, alternating-current switch SW1, load are sequentially connected in series in one end of adjustable ac source, and one of conduct piece is serially connected in load
Output end, another conduct piece are connected with the other end of adjustable ac source.
The present invention is further improved, and the voltage range of the adjustable ac source is 50~120V, and input power is kept
Between 8~15W.
The present invention is further improved, and when dismantling, one of conduct piece and upper magnetic core are electrically connected, another is led
Electric part and lower magnetic core are electrically connected.
Compared with prior art, the beneficial effects of the present invention are: not damaging magnetic core, insulating tape and enameled wire premise
Under, easily disassemble high frequency transformer.
Detailed description of the invention
Fig. 1 is that one embodiment of the invention disassembles circuit diagram.
Specific embodiment
The present invention is described in further details with reference to the accompanying drawings and examples.
As shown in Figure 1, for the ease of assembling production, complete high frequency transformer usually by upper and lower two magnetic cores+
Skeleton+coil composition, for convenient disassembly, the present invention needs to build dismantling circuit, and dismantling circuit of the invention includes adjustable friendship
Galvanic electricity source 1, switch SW1,3, AC power meter 2, alternating-current switch SW1 are loaded and is respectively used to connection magnetic core both ends and leads to for magnetic core
2 conduct pieces 4 of electricity, wherein the AC power meter 2, alternating-current switch SW1, load 3 are sequentially connected in series in adjustable ac source 1
One end, one of conduct piece 4 is serially connected in load outputs, the other end phase of another conduct piece 4 and adjustable ac source 1
Even.
The load 3 of this example is the common tungsten lamp bubble that power is 100W, and the AC power meter 2 of this example includes 21 He of ammeter
Voltmeter 22.The conduct piece 4 of this example is conductive clip.
The traditional osram lamp of the present invention and magnetic core series connection, are powered to magnetic core both ends, wherein series bulb can play magnetic core
To protective effect, due to forming current loop, when there is electric current to flow through magnetic core, the ground of upper and lower two magnetic core contact surfaces inside magnetic core
Sheet resistance value is maximum, and fever is also the largest, and magnetic core generates heat when to magnetic core energization 1-2 minutes, causes varnish to melt, loses viscous
The effect of magnetic core is tied, easily lossless can thus be dismantled the biggish magnetic core of resistivity ratio.
Disassembling method of the invention specifically:
1, the insulating tape place to go on magnetic core of transformer, magnetic core is exposed；
2,2 electric conductors are connect respectively on upper and lower two panels magnetic core 51,52；
3, open alternating-current switch SW1, connect adjustable ac source, due to magnetic core fever after resistance decrease, by electric current
Increasing, power is increasing, and heating temperature is too high, is easy to burn out magnetic core and coil.So this example adjusts AC power source
Voltage allows input power to remain within 8~15W between 50~120V.
4, magnetic core persistent fever for a period of time after, can power off, clamp magnetic core with heat-barrier material, can easily unplug up and down
Two panels magnetic core, without destroying magnetic core.
The lossless disassembling method of high frequency transformer of the invention, under the premise of not damaging magnetic core, insulating tape and enameled wire, gently
Demolition solution high frequency transformer.And it is applied widely, it can be used for LED illumination, non-destructive testing, reverse-engineering, maintenance, sample preparation etc.
Purposes.
The specific embodiment of the above is better embodiment of the invention, is not limited with this of the invention specific
Practical range, the scope of the present invention includes being not limited to present embodiment, all equal according to equivalence changes made by the present invention
Within the scope of the present invention.
