    摘要: An EMP-eliminator is to be created which is simultaneously applicable for multiple frequency bands and highest frequencies and at the same time allows transmission of AC/DC supply voltages. For this purpose a casing (20) set in an outer line (10) is provided as well as a line (24) connected in an electrically conductive manner to an inner line of a coaxial line (30). The line (24) is connected in an electrically conductive manner with the equipment casing (20) or its face side via a gas filled overvoltage suppressor (28). The gas eliminator (28) is set into a threaded cover and thus can be exchanged. Between the equipment casing (20) and the line (24) several bushes (25,26) connected electrically to the line are provided. The length of the line (24) corresponds to the .lambda./4 length of the lowest transmitted frequency band. Several serially connected resonant cavities result which are matched in their length to different midband frequencies. With this kind of serially connected resonant cavities it is easily possible to transmit several frequency bands and thus protect end apparatuses from interference current impulses. The capacitance of the overvoltage suppressor (28) is decoupled by the line (24) and the bushes. (25,26) to such a degree that use up to 18 GHz is possible.

    摘要: The fine protection circuit arrangement is to reduce the remaining residual impulses on gas tube charge eliminators. This is to be achieved by means of a cascading of a gas tube charge eliminator or a .lambda./4 shorting stub with a fine protection circuit. The fine protection circuit connected to the gas tube circuit eliminator or .lambda./4 shorting stub reduces the relatively high residual voltage at the output of the gas tube charge eliminator or .lambda./4 shorting stub to a minimal value.
