Technical field

The present invention relates to fuse technologies field more particularly to a kind of quick response formula AC fuses.

Background technique

Fuse refers to when electric current is more than specified value, so that melt is fused with the heat that itself is generated, the one of disconnecting circuit Kind electric appliance；In the power system, to prevent in electric system, electric current is excessive to cause route to damage, it usually needs setting fuse.

Current fuse mainly includes disposable fuse and can restore fuse；Current disposable fuse, one Denier is blown, then needs integral replacing, is inconvenient；Current restores fuse, and principal mode is bimetal thermal relay, Its on-off component is made of the bimetal leaf of different thermal deformation coefficients, when electric current is excessive, keeps bimetallic temperature excessively high, double gold Belong to piece and disconnect contact due to deformation, until being connected again after cooling；Both modes are the ability after electric current increases a period of time Tripping action can be made, needs to be easy to cause irreversible wound to electrical equipment during this period of time by the longer response time Evil, especially in home circuit, damage electric appliance is extremely easy to cause fire while causing economic loss, thus to the life of user Safety threatens.

Summary of the invention

Slower problem is responded the purpose of the present invention is to solve fuse in the prior art, and the one kind proposed is quickly Response type AC fuse.

To achieve the goals above, present invention employs following technical solutions: a kind of quick response formula AC fuse, packet Outer box are included, the inner wall of the outer box is fixed with the isolation board with through slot, and the sidewall weld of the isolation board has one group of connecting spring, The connecting spring is welded with line position magnetic patch far from one end of isolation board, and the line position magnetic patch is welded far from one end of connecting spring There is closed coil, the both ends of the closed coil are respectively connected with slide plate, are fixed on the symmetrical two sides inner wall of outer box and two The power connecting sheet that a slide plate offsets, the inner wall of the isolation board are symmetrically fixed with two connection sheets, and the inner wall of the outer box, which is equipped with, to be used The resetting-mechanism of delay power after open circuit, the inner wall of the outer box is fixed with positive coil, cathode coil and capacitor, described Wherein one end of positive coil and cathode coil is connect with the both ends of capacitor respectively, it is described anode coil and cathode coil it is another One end is connected with diode jointly.

In above-mentioned quick response formula AC fuse, the resetting-mechanism includes the metal being welded on outer box inner wall Silk, the wire are fixed with reset magnetic patch close to one end of connection sheet, and the wire is metamorphosis gold of the torsion in twisted shape Category is made.

In above-mentioned quick response formula AC fuse, the both ends of the wire by conducting wire respectively with capacitor The both ends of both ends connection, the capacitor are connect with two connection sheets respectively by conducting wire, and two connection sheets, which pass through, to be led The connection of the both ends of line and wire.

Compared with prior art, the present invention has the advantages that

1, in the present invention, closed coil connects will generate alternation induced magnetic field in main circuit, and induced magnetic field intensity Size and the passage current size of main circuit are positively correlated, and are incited somebody to action when the passage current of main circuit increases so that closed coil is in magnetic It is mobile to isolation Board position under power effect, and power connecting sheet is detached from when main circuit current increases to abnormality, form main circuit Open circuit, and in the open circuit process of completion in a flash of main circuit current exception, response quickly will not be made main circuit because of high current At damage；

2, the alternation induced magnetic field that hot-wire coil generates will make positive coil, cathode coil, diode and capacitor shape At circuit in generate induced current, and the charging to capacitor is formed under the effect of the one-way conduction of diode, in main circuit Capacitor will make its deformation that heats up to wire electro-discharge after power-off, change to form line position magnetic so that resetting magnetic patch pole orientation The reset of block and closed coil, it is auto-power on after completing power-off.

In conclusion the present invention charges to capacitor in main circuit normal power-up, increase extremely in main circuit current Moment, closed coil and line position magnetic patch are subjected to displacement the open circuit to form main circuit, and then are quickly formed and protected to main circuit, and Closed coil return after the time of capacitor discharge one end, the automatic Power resumption of main circuit simultaneously give user's enough reaction time.
