The electronic fly disinfestation simple and easy system for all electrical fly online, you can wipe out. The apparatus shown
in Figure 1 circuit. The entire device consists of 220V mains powered directly by the rectifier. R3, R4, R5, C1 and double base diode relaxation oscillator, the output pulse signal for controlling the thyristor turn-on and turn-off. SCR is not in the off state, and then the electricity equivalent to the resistors R6 and L1 C3 is charged by VD rectified. When VS is triggered conduction, charge through the guide on the C3 through the SCR and the equivalent resistance L1 rapid discharge. When the discharge current zero, SCR and automatic shutdown. This cycle repeated in the transformer secondary L2 gained the high-voltage pulse voltage, this voltage is applied by a number of equidistant metal filaments electric network, power grid with a bait, flies smell from the bait touches the grid when landing being electrocuted, dead flies automatically fall away from the space network, to automatically fly disinfestation effect.Resistance R3 between 20-50K choice. Oscillation capacitor C1 best selection of tantalum capacitors, such as use an ordinary electrolytic capacitors, should ensure that the leakage current is sufficiently small. C2 for the filter capacitor, the pressure in the premise of ensuring capacity bigger is better. Transformers 14 Core black and white TV line output transformer primary with µ = 0.1mm enameled wire around 600 turns, using the original ignition coil secondary coil. After winding transformer is subject to drying dipping process. Changing the resistance value of R3, the oscillation frequency in the range of 10-20Hz, the output voltage can be measured at this time is about 4kV. Fly box size 320 225 70mm3. Fly box at the top of the 14th with a wire made of high-voltage grid. Adjacent wire distance of 7mm. Fly box front side opening one hole in order to remove the dead flies. Use should be sealed to prevent flies out from the hole. To prevent children from touching power, Fly boxes should be placed a few meters in height from the ground, and should be fixed firmly. "R3, R4, R5, C1 and double base diode relaxation oscillator, the output pulse signal for controlling the thyristor turn-on and turn-off. SCR is not in the off state, the mains via the rectifier and then by VD R6 and equivalent resistance L1 to charge C3. when VS is triggered conduction, the charge on C3 by conducting thyristor L1 and the equivalent resistance of rapid discharge when the discharge current zero, and SCR automatic shutdown. this cycle repeated in the secondary of the transformer L2 gained the high-voltage pulse voltage, this voltage is applied by a number of equidistant metal filaments electrical network, power grid has bait, flies smell from the bait, reach landing grid when electricity is dead, dead flies from the network automatically dropped from space, to automatically fly disinfestation effect.
