Abstract
The design of the triggering circuit 1 of the overvoltage protection, connected via three poles 4 to the spark gap of the overvoltage protection, provided with the first input terminal 2 and the second main terminal 3, whose principle consists that an auxiliary electrode 7 of the spark gap 4 is connected in series to the first varistor 8 and one end of the secondary winding 14 of the transformer 13, the other end of which is connected to the second main electrode 6 of the spark gap 4 and the second input terminal 3, whereas one end of the primary winding 15 of the transformer 13 is connected in series to the gas discharge tube 10, the second varistor 9, resistor 11 and capacitor 12, connected to the other end of the primary winding 15 of the transformer 13, connected to the second input terminal 3, whereas the junction connecting the second varistor 9 to the resistor 11 is interconnected with the junction, connecting the first input terminal 2 to the first main electrode 5 of the spark gap 4.
