Abstract
The utility model discloses a high-frequency transformer which comprises a framework, wherein a magnet is arranged in the center of the framework, primary coils, a first insulating layer, secondary coils and a second insulating layer are sequentially arranged on the outer side of the framework from inside to outside, pins are arranged on the bottom of the framework, a lead is arranged on the magnet and a fuse is arranged on the lead. When faults occur in a circuit, currents are amplified and the fuse is melted, and therefore the effect that the high-frequency transformer is not damaged is guaranteed.
Description
Technical field
The utility model relates to a kind of high frequency transformer, belongs to the transformer technology field.
Background technology
Transformer is the device of conversion alternating voltage, electric current and impedance, when being connected with alternating current in the elementary coil, just produces exchange flux in iron core or the magnetic core, makes and induces voltage or electric current in the secondary coil.When circuit breaks down or is unusual, be accompanied by electric current and constantly raise, and the electric current that raises might damage some important devices or valuable device in the circuit, also might burn circuit even cause fire.
Summary of the invention
The utility model proposes a kind of high frequency transformer with fuse, in order to play the effect of transformer in the protective circuit, prevent that transformer from being burnt.
For realizing this purpose, the structure that the utility model adopts is: a kind of high frequency transformer, comprise skeleton, frame center is provided with magnet, and the skeleton outer felt is around primary coil, primary coil outer wrapping the first insulating barrier, the first insulating barrier twines secondary coil outward, secondary coil outer wrapping the second insulating barrier is connected with a lead-in wire on the magnet, lead-in wire is provided with fuse.
Described skeleton bottom is provided with many stitch.
What described the first insulating barrier and the second insulating barrier adopted is polyester film adhesive tape.
What described primary coil and secondary coil adopted is polyester-imide QZY-2 enamelled wire.
Its beneficial effect is: after having fault in the circuit, electric current increases, and fuse will fuse, and just can guarantee that high frequency transformer does not sustain damage.
Description of drawings
Fig. 1 is the utility model sectional structure chart.
Embodiment
Disclosed all features in this specification, or the step in disclosed all methods or the process except mutually exclusive feature and/or step, all can make up by any way.
Disclosed arbitrary feature in this specification (comprising any accessory claim, summary and accompanying drawing) is unless special narration all can be replaced by other equivalences or the alternative features with similar purpose.That is, unless special narration, each feature is an example in a series of equivalences or the similar characteristics.
As shown in Figure 1, a kind of high frequency transformer, comprise skeleton 1, skeleton 1 center is provided with a strip magnet 2, skeleton 1 outside is wrapped up primary coil 3, the first insulating barrier 4, secondary coil 5 and the second insulating barrier 6 from inside to outside successively, and what primary coil 3 and secondary coil 5 adopted is polyester-imide QZY-2 enamelled wire, and what the first insulating barrier 4 and the second insulating barrier 6 adopted is polyester film adhesive tape, in order to improve the insulation property of transformer, prevent electric current punch through damage transformer.Skeleton 1 bottom is provided with many stitch 7, makes things convenient for transformer to peg graft and installs.Be connected with a lead-in wire 8 on the magnet 2, be connected with fuse 9 on the lead-in wire 8, when electric current was excessive in the circuit, fuse 9 will fuse, thereby played the effect of protection transformer.
The utility model is not limited to aforesaid embodiment.The utility model expands to any new feature or any new combination that discloses in this manual, and the arbitrary new method that discloses or step or any new combination of process.
