摘要： Arrangement for secure system isolation of surge arresters, particularly varistors 1, in the presence of temporary overvoltages as a result of a fuse 4 in series with the surge arrester 1 tripping out, wherein the surge arrester 1 has a flashover gap 6 or is electrically connected to a separate flashover gap 6, wherein the surge arrester 1 is provided with an encapsulation 7 or housing and the encapsulation 7 or housing has an opening, which is directed towards the respective flashover gap, such that a flow of gas that arises when the surge arrester 1 is subject to thermal load or is burning up reaches the flashover gap, resulting in a reduction in the flashover voltage of the flashover gap and resulting in a flow of current with the fuse in series tripping out.

摘要： The invention relates to a surge arrester (1) for use in the power supply of low-voltage networks, in particular for use between a neutral conductor N and a potential equalization means PE, comprising a cylindrical housing (2), two electrodes (3, 4) arranged axially opposite each other, and an arc chamber (5) formed inside the housing (2), wherein the arc chamber (5) is axially bounded by the two electrodes (3, 4) and a spark gap is formed between the two electrodes (3, 4) such that an arc is produced when the spark gap between the two electrodes (3, 4) is ignited. In the case of the surge arrester according to the invention, the blowing out of ionized gases can be dispensed, because two chambers (6, 7) are formed within the housing (2), each of which two chambers is connected to the arc chamber (5) by means of two channels (8, 9) such that hot ionized gas can flow from the arc chamber (5) into the chambers (6, 7) after the ignition of the spark gap, wherein the volume of the two chambers (6, 7) together is greater than the volume of the arc chamber (5) and wherein the two chambers (6, 7) are arranged on opposite sides of the arc chamber (5) in a longitudinal direction of the housing (2) and each have an axial and a radial distance from the arc chamber (5).

摘要： The invention relates to a spark gap with a capacitive energy accumulator. According to the invention, said spark gap (14, 15) is fed via a plurality of annularly arranged capacitors (19), said capacitors being electrically connected to the anode (11) and cathode (12) via annular (21, 26) and conical (22) and/or funnel-shaped (27) conductors. Due to this, impedance jumps can be avoided. It is also possible for the conductor to have a cross-sectional surface as large as possible in a small area. Due to this, the claimed spark gap has a switch behaviour with a voltage pulse having a high rate of rising as long as the spark gap is sparked. This leads to a good predictable switching behaviour of the spark gap. Said spark gap can be used for example to produce pulses from monochromatic x-rays.

摘要： An improved device for over-voltage protection is disclosed. A triggerable three electrode GDT (Gas Discharge Tube) is in the device used for discharging voltage. The GDT is connected between an input of the device and ground, and has its trigger electrode connected to a secondary side of a transformer. The transformer is arranged for producing a trigger signal in response to a voltage on the input for triggering said GDT into a conducting state. According to the present invention, a primary side of the transformer is connected to the input via a capacitor and a resistance, wherein a current flowing from the input through said resistance charges said capacitor when the voltage on the input increases. A thyristor is connected to ground, from a point between the resistance and the capacitor. The thyristor is arranged to start conducting when the input voltage reaches a predetermined level, thereby discharging the capacitor through the thyristor to ground and creating a pulse on the primary side of the transformer. This pulse is then transformed into the trigger signal by the transformer.
