Black light insecticide circuit

The high-voltage insect killer lamp uses a fence mesh high-voltage power grid , surrounding the black light tube. The power grid is divided into two groups, insulated from
each other, and connected to the high-voltage side of the 220V/4000V transformer. At this time, the black light lamp attracts the pests at the lower end of the power grid
. When the pests fly into the gap of the power grid, the
pests will be electrocuted immediately due to the high voltage of the power grid. When the high-voltage power grid kills too many pests, a short
circuit will occur, and the bulbs EL2 and EL3 will light up automatically, indicating that the power grid needs to be cleaned. The circuit is shown in Figure
23-6. The high-voltage step-up transformer can be wound by itself. You can use a 100VA row
lamp transformer to change the winding. Remove the secondary coil, write down the number of turns of the 36V coil, calculate
how many turns the Jtt transformer should be wound for 1V, and then use a thinner enameled wire to calculate the number of turns for 4000V. Wind how
many turns according to this number of turns. After winding, the high and low voltage sides are insulated,
and a larger power incandescent bulb is connected in series, connected to the switch, and then connected to the 220V power supply,
black light line and fluorescent light line . Exactly the same. Connect the circuit, install the transformer,
incandescent lamp, switch and fuse in an insulating box, install the black light lamp on a large
lamp stand, and set up a uniform high-voltage grid around the lamp to make a high-voltage
insect-killing lamp. When using high-voltage insect-killing lamps, you should pay attention to the following issues:
    1) A protective fence should be erected around the high-voltage insect-killing lamp and a protective iron lock should be added
to prevent humans and animals from entering the protective fence when the power is on. 2) High-voltage wires should be insulated
wires with higher voltage resistance , and insecticidal lamps should be installed at a distance of more than 2. Sm from the ground. 3) A dedicated person should be responsible for turning on and off the high-voltage insecticidal lamp, and the distribution box should be locked to prevent children from accidentally touching it.
