Description
Technical field
The present invention relates to electric field, specifically a kind of high-energy electronic igniter circuit.
Background technology
In earlier stage high energy oil gun ignitor circuit is in engineering application in my company, and constantly generation transformer burns out the phenomenon burnt out with current-limiting resistance, thus has an impact to production.Find that current-limiting resistance R1 power is too little after deliberation, the alternating current of 2500V is after full-wave rectification, and by R1 current-limiting resistance to the charging of 6uFC1 storage capacitor, when reaching the place value of discharge tube 2500V, the electric energy be stored in C1 discharges to burning torch head.Charging current is i=(U-U
0)/ r × e
-t/ τ), substitution data calculate average current and are about 270mA, or are that 20 burnt energy are calculated according to power output frequently every after high energy oil gun ignitor circuit full-wave rectification in early stage, can show that average current is 275mA; And the rated current of the high-tension coil of 700VA2500V transformer is about 280mA; Under air-proof condition, when operating, long environment temperature rises compare higher position and likely burn out transformer.And the power hair of resistance is calculated as I
2r ≈ 290W, after full-wave rectification, 4 1K/50W working times are slightly grown and also can burn, and same reason, after halfwave rectifier, the resistance of 2 1K/50W is also easily burnt.
Summary of the invention
For above-mentioned technical problem, the invention provides a kind of transformer and current-limiting resistance can work long hours, be not easy to burn out, in machine, resistance consumption is low, maintenance safety, lower-cost ignitor circuit.
The present invention is achieved by the following technical solution: a kind of high-energy electronic igniter circuit, comprise step-up transformer, resistance R1, resistance R2, resistance R3, electric capacity C1, electric capacity C2, switch S 1, switch S 2, discharge tube and rectification circuit, switch S 1 is connected with the primary coil of step-up transformer, electric capacity C1 connects with the secondary coil of step-up transformer, the input of rectification circuit is connected with the secondary coil of step-up transformer, the output of rectification circuit is connected with one end of electric capacity C2 with one end of resistance R1 respectively, the other end of resistance R1 is connected with the other end of electric capacity C2, resistance R2 is in parallel with electric capacity C2, switch S 2 is in parallel with electric capacity C2 again after connecting with resistance R3, one end of semiconductor discharge plug is connected through the positive pole of discharge tube with electric capacity C2, the other end is connected with the negative pole of electric capacity C2.
Adopt ac capacitor C1 to working portion high-voltage alternating current limliting, because the capacitor value of design is Z
c=1/ ω C(is determined by the capacitance of C, ω=2 π f, f=50), the maximum current value I=2500/Z that restriction performance loop produces
cbe less than the load current value of transformer high-voltage coil.Present current limiting capacitance gets 0.11uf, and calculating the maximum effective current value in loop is 86.3mA, (when working portion short circuit).320VA capacity got by present transformer, and high pressure is 2600V, and the rated current of high-tension coil is I=320/2600=123mA.Maximum operating currenbt is less than rated current 36.7mA, and transformer can safe long continuous operation, and the transformer (prior art is 700VA) owing to have employed the lower 320VA of capacity, and therefore, cost is lower.
Resistance R1 is rectifying tube protective resistance, and heating only has 1W, and resistance R2 is bleeder resistance, and caloric value is about 5W, and resistance generates heat altogether for 6W, and in machine, resistance consumption is low.
Owing to adding S1 and S2 microswitch, when needs overhaul, uncap, switch S 1 disconnects, Simultaneous Switching S2 closes, igniter power-off, and the electric energy being discharged rapidly electric capacity C2 storage by resistance R3, so that safety inspection, close the lid after maintenance, switch S 1 closes, and Simultaneous Switching S2 disconnects, the normal power transmission of equipment.
As improvement of the present invention, also comprise magnet ring, described magnet ring is enclosed within discharge end.
Due to first time electronic striking and second time electronic striking between have interval time, when first time electronic striking ignitor circuit conducting, magnet ring can produce induced-current, so during second time electronic striking ignitor circuit conducting, electric current when being first time electronic striking by the electric current of circuit adds the middle induced-current produced, then igniter discharge current increases, and more easily lights a fire.
As a further improvement on the present invention, also comprise comparison resistance R4, one end of comparison resistance R4 is connected with resistance R3 through discharge tube, and the other end is connected with switch S 2.
If discharge tube discharges for a long time, must burn out semiconductor discharge plug, the comparison resistance R4 of increase, owing to being connected with discharge tube, can sharing a part of electric energy, thus effectively protect semiconductor discharge plug.
In sum, beneficial effect of the present invention is, transformer and current-limiting resistance can work long hours, and be not easy to burn out, in machine, resistance consumption is low, maintenance safety, and cost is low.
