A high voltage pulse generator essentially comprising - a chamber which is in the shape of a hollow cylinder, - at least two air ducts which are placed in the chamber and one of which enables to blow air into the chamber while the other enables to take air from the chamber, - at least two capacitors which are placed in the chamber and enable to store electric charges. - at least two electrodes which are connected as one to every sequential capacitor such that it will establish arcing from one capacitor to the other and the distance between which can be adjusted according to the voltage value desired for the arc, - at least one cylindrical upper chamber which is in the chamber and proceeds coaxial with the circular cross-section of the central chamber, - at least one cylindrical load resistance which proceeds coaxial such that it will connect the circular cross-sections of the upper chamber, - at least one ground line which enables the current passing through the load resistance to be transmitted to earth, - at least one filter which enables foreign particles such as dust from the outer environment to be filtered, - at least one compressor which enables the air passing through the filter to get pressurized, - at least one dryer which enables the air pressurized by the compressor to get dried, - at least one air container wherein the pressurized air dried by the dryer is stored, - at least one heater which enables the air taken from the air container to be heated, - at least one regulator which regulates the pressure and the flow rate of the air taken from the heater and enables to give the air, whose pressure and flow rate is regulated, into the air duct enabling to give air into the chamber; and characterized by - at least two air nozzles which are placed such that there will be one on the lateral surface of each air duct and which enable the air flow between the air duct and the chamber and which are aligned with the place where the arc between electrodes occurs and thus enables the air whose structure changes because of the arc to be removed, - a chamber which is in the shape of a hollow cylinder, - at least two air ducts which are placed in the chamber and one of which enables to blow air into the chamber while the other enables to take air from the chamber, - at least two capacitors which are placed in the chamber and enable to store electric charges. - at least two electrodes which are connected as one to every sequential capacitor such that it will establish arcing from one capacitor to the other and the distance between which can be adjusted according to the voltage value desired for the arc, - at least one cylindrical upper chamber which is in the chamber and proceeds coaxial with the circular cross-section of the central chamber, - at least one cylindrical load resistance which proceeds coaxial such that it will connect the circular cross-sections of the upper chamber, - at least one ground line which enables the current passing through the load resistance to be transmitted to earth, - at least one filter which enables foreign particles such as dust from the outer environment to be filtered, - at least one compressor which enables the air passing through the filter to get pressurized, - at least one dryer which enables the air pressurized by the compressor to get dried, - at least one air container wherein the pressurized air dried by the dryer is stored, - at least one heater which enables the air taken from the air container to be heated, - at least one regulator which regulates the pressure and the flow rate of the air taken from the heater and enables to give the air, whose pressure and flow rate is regulated, into the air duct enabling to give air into the chamber; and characterized by - at least two air nozzles which are placed such that there will be one on the lateral surface of each air duct and which enable the air flow between the air duct and the chamber and which are aligned with the place where the arc between electrodes occurs and thus enables the air whose structure changes because of the arc to be removed,
