The proposed electrosurgery, I am sure, will find its rightful place in the kitchens have gas stoves, when the ignition of the gas burner appliances and other devices with the “blue fuel”. It is convenient and trouble free. It can make for a night or two, pre-armed with a small piece of one-sided foil fiberglass and a minimum of inexpensive and common parts. A faithful guide to action will serve as a sketch of the printed circuit Board and Assembly drawing.
The conductors of the PCB’s made by removing excess foil with a knife, a drill or chemical etching. Installation is carried out by solder-side conductors, by providing radio equipment subject to conditional image on the semiconductor diode and the body of the thyristor.
The principle of operation of the lighter based on the cycles of charge-discharge of capacitor C1. This happens when pressed (for time t<5 s) the SV1 button.
During the positive half cycle of steps network voltage capacitor C1 is charged. Through resistor R1, diode VD1 and the primary winding of the transformer T1. And when entering the negative half-cycle C1 is discharged. But through the open thyristor VS1, VD2 diode, the winding I of the transformer.
T1 — enhancing. In its secondary winding is induced a high voltage the voltage that causes arcing in the gap between the electrodes of the spark gap E1 and ignites the gas.
The transformer is performed on 20-mm segment of the ferrite rod of circular or rectangular cross-section with m=400…2000 (from the magnetic antenna of any radio). Wrapped around the rod two or three layers of adhesive tape, he wound up on sections (6×90 turns) secondary winding wire of PEV-2 0,06— 0,07. This is perhaps the most important operation. Wrapping high-voltage winding of two layers of an insulating tape with subsequent impregnation of it with paraffin or epoxy resin, are transferred to the next operation is the winding of the primary winding of only four turns. Do it over high-voltage. Wire uses the same brand (sew-2), but more with a diameter of 0.4 — 0.5 mm.
