Description

Neon lamp high-frequency magnetic leakage electronic transformer

Technical field

The utility model relates to a kind of rainbow lamp transformer.

Background technology

Neon light relies on dedicated transformer to produce high pressure and luminous, and at present used silicon steel chip leakage transformer electric energy loss is big, makes use cost higher, makes the neon light luminous intensity low and electronic type transformer power output is low.

Summary of the invention

In order to overcome above-mentioned defective, the utility model provides a kind of neon lamp high-frequency magnetic leakage electronic transformer, and this transformer power consumption is low, and can make the neon light luminous intensity very high.

The utility model for the technical scheme that solves its technical problem and adopt is: a kind of neon lamp high-frequency magnetic leakage electronic transformer, form by frequency-variable electronic oscillator circuit and leakage transformer, the input termination civil power of frequency-variable electronic oscillator circuit, the input of the output termination leakage transformer of frequency-variable electronic oscillator circuit, the output termination load of leakage transformer, the leakage transformer main body is a FERRITE CORE, the peristome that is two " E " fonts involutes in opposite directions, primary coil and secondary coil be set around respectively the centre one of " E " word horizontal on, two lead-out wires of primary coil are input, two lead-out wires of secondary coil are output, be provided with two ferrite leakage field sheets again, two ferrite leakage field sheets be individually fixed in the leakage transformer main body on, in following and be between primary coil and the secondary coil.

The beneficial effects of the utility model are: because through the voltage of frequency-variable electronic oscillator circuit output existing certain improve (can set according to actual conditions), ferrite has higher magnetic flux density and low iron loss again, the voltage of exporting behind this creation leakage transformer can reach high value, and the power consumption of leakage transformer of this sample creation own just less, power output is bigger.Producing high-frequency current through the frequency-variable electronic oscillator circuit can make the efficient of this creation be much higher than the leakage transformer that silicon steel sheet is formed; Compare with the similar electronic transformer of power for another example, the neon light brightness after its combination is its one times.Therefore this creation can provide maximum power output under the less situation of own loss, sends the strongest light for neon light tube (load).

Description of drawings

The utility model is described in further detail below in conjunction with the drawings and specific embodiments.

Fig. 1 has connected the schematic diagram of load for the utility model;

Fig. 2 is the schematic diagram of leakage transformer.

Embodiment

Embodiment: referring to Fig. 1 and Fig. 2, a kind of neon lamp high-frequency magnetic leakage electronic transformer, form by frequency-variable electronic oscillator circuit 1 and leakage transformer 2, the input termination civil power of frequency-variable electronic oscillator circuit 1, the input of the output termination leakage transformer 2 of frequency-variable electronic oscillator circuit 1, the output termination load 3 of leakage transformer 2, leakage transformer 2 main bodys are FERRITE CORE, the peristome that is two " E " fonts involutes in opposite directions, primary coil 22 and secondary coil 21 be set around respectively the centre one of " E " word horizontal on, two lead-out wires 4 of primary coil 22 are input, two lead-out wires 5 of secondary coil are output, be provided with again 23, two ferrite leakage fields of two ferrite leakage field sheets sheet 23 be individually fixed in the leakage transformer main body on, in following and be between primary coil and the secondary coil.

The leakage transformer main body is two " E " font peristomes and involutes in opposite directions in this example; the peristome that also can be " E " and " C " involutes in opposite directions; as long as the limit of horizontal being extended down to " C " word in the middle of " E " word, this also is this routine claimed scope.

Two " E " word peristomes also can engage fully in opposite directions to the fashionable gap of leaving in this example again, all are this routine claimed scope.

In this example, two ferrite leakage field sheets that are provided with in opposite directions can change one into again, and only effect is relatively poor, and same domain technical staff expects very easily, is similarly this example otherwise protection range.

Operation principle of the present utility model is: civil power can obtain a higher output voltage through the frequency-variable electronic oscillator circuit, then again the input voltage of this higher voltage as leakage transformer, after leakage transformer output meets the high voltage of neon light job requirement, the input voltage that therefrom can find out leakage transformer is with regard to higher (can artificially set), therefore under identical output voltage the power consumption penalty of this routine leakage transformer itself with regard to little (because of voltage rising absolute value less, higher magnetic flux density of soft magnet material tool and low iron loss again), and can make the neon light luminous intensity very strong.

During use, be short-circuited, then under the effect of ferrite leakage field sheet, electric current is only flowed at primary coil, and secondary coil no current (this is the known free and public technology of same domain technical staff) be safe and effective as load.

When using, reality adjusts induced current on primary coil and the secondary coil by ferrite leakage field sheet, make and to obtain voltage and current (this need not pay the technological means that creative work just can be realized for the same domain technical staff, and this example is not describing in detail) preferably in the load.Rationally the ratio of adjustment primary coil and secondary coil (be familiar with by the same domain technical staff by principle, this example is not describing in detail), be can be to provide at the frequency-variable electronic oscillator circuit under the high-frequency current condition of upper frequency, make transformer that maximum power output can be provided under the less situation of own loss, send the strongest light for neon light tube (load).
