procedure for the continuous operation of a marx generator, in particular getriggerten several marx generators for pressure control and abbranddetektion in the funkenstrecken

摘要

The invention relates to the continuous triggered operation of a Marx generator, particularly several Marx generators in the optimal operating point over a longer period of time for the purpose of pressure regulation and erosion detection in the spark gaps. An overvoltage that increases with time is superposed on at least one spark gap of a Marx generator, said overvoltage leading to the breakdown of the spark gap. The overvoltage value at the time of breakdown is determined and used for regulating the pressure in the spark gap tower and/or the distance of the caps. The distance is determined from the relation between the breakdown voltage, the pressure in the tower and the distance between the gaps of the triggered spark gap, the breakdown voltage and pressure being known, and used for erosion detection. In the case of adjustable caps, erosion detection is achieved on the basis of a measurement of the displacement path in addition to the voltage and pressure measurement. The ignition delay of each Marx generator is measured for the purpose of a temporally defined triggering of at least two Marx generators. The signals are triggered in a temporally graduated manner in such a way that the initial voltages or initial currents of all Marx generators increase within a structurally conditioned scattering range at the respective desired moments.
