Abstract
The invention discloses an anti-thunder circuit. The anti-thunder circuit comprises a rapid conduction diode, a current-limiting resistor, a first voltage dependent resistor, a second voltage dependent resistor and a discharge tube, wherein the rapid conduction diode and the current-limiting resistor are connected in series to form a first branch circuit, the first voltage dependent resistor and the second voltage dependent resistor are connected in series to form a second branch circuit, and the first branch circuit and the second branch circuit are connected between a null line and a fire line after being connected in parallel; the connection point of the first voltage dependent resistor and the second voltage dependent resistor is connected with the ground through the discharging tube. According to the anti-thunder circuit, the anti-thunder effect is achieved through the two branch circuits connected between the null line and the fire line, when no thunder enters in, the two branch circuits are both in a high impedance state, when thunder enters, the thunder rapidly passes the connection point between the first voltage dependent resistor and the second voltage dependent resistor to make the discharging tube conductive to discharge, the thunder is conducted into the ground, a good anti-thunder effect is achieved, and electric equipment is protected.
