GAZ ELECTRONIC SWITCH (PSEUDO-SPARK SWITCH)

摘要

a switch comprises a gas discharge chamber, in which are arranged electrodes, i.e., a cathode (11) and an anode (12), (d) mutually spaced one from the other and separated by an electrically insulating wall (9a) of a ceramic material or glass.the cathode (11) is provided with an orifice (5) and the electrodes (11, 12) are connected by a sealed ceramic metal binding or fusion with the insulating wall (9a).in the gas discharge chamber is an ionizable gas filling pressure, low pressure, p, so that the ignition of a gas discharge between the electrodes (11, 12), a tension is located on the left descending branch of the paschen curve and.in the case of at least one of the two electrodes (11, 12), the connecting lines (4), on which the corresponding electrode (11, 12), the gas and the wall (9a) are present a minimum difference in relation to the opposite electrode (12, 11) of more than the gap (d), if the electrode (11),(12) to be separated from the wall (9a) of a slit (3) whose width is less than (d).
