    摘要: Provided in the present disclosure is an arc compression-based arc-extinguishing lightning-protection gap device. The device comprises a lightning protector main body and an arc-striking electrode. The arc-striking electrode is fixedly mounted at one end of the main body. The other end of the main body is fixedly mounted, by means of a link fitting, to a crossarm or one end of an insulator string. The lightning protector main body is provided with an arc-extinguishing path consisting of several arc-extinguishing channels in a repeated Z-shaped arrangement. An arc-extinguishing tube at an inlet of a first arc-extinguishing channel of the arc-extinguishing path is connected to the arc-striking electrode via an arc-guiding rod, and an arc-extinguishing tube at an outlet of a last arc-extinguishing channel is connected to the link fitting. A three-way tube is provided at a joint of two adjacent arc-extinguishing channels; two ends of the three-way tube are each provided with one arc-guiding electrode; and the arc-guiding electrode has one end extending into the three-way tube and the other end connected to a nearby arc-extinguishing tube via direct contact or a wire. The present disclosure has the advantages of simple structure, reasonable design, improved arc-extinguishing performance, and stable operation.

    摘要: The invention relates to a non-rotationally symmetrical spark gap, in particular a horn spark gap with a deion chamber, a multi-part insulating material housing (1) as a support and receiving body for the horn electrodes and the deion chamber, means for conducting the gas flow related to the arc, wherein the insulating material housing (1) is divided on the plane defined by the horn electrodes and has two half shells, and plug or screw connections (4, 5) which lead out on the end face. According to the invention, with the exception of the sections of the plug or screw connections (4, 5) leading out, the insulating material housing is surrounded on all sides by a cooling surface (14) which is near the housing and lies against the housing surface, and the cooling surface (14) is at least partly supported on webs (8) which are designed to conduct the gas flow on the outer surface of the half shells.

    摘要: A surge arrester for the power supply of low-voltage systems, having a housing, two electrodes which are situated axially opposite one another, an arc combustion chamber formed in the interior of the housing, and a trigger aid. A spark gap is formed between the two electrodes so that an arc is produced when the spark gap between the two electrodes is triggered, the axial distance between end faces of the two electrodes being so large that the arc voltage is greater than the expected line voltage. Conversion of energy within the surge arrester is reduced by the arc combustion chamber having an inner region and at least one expansion region into which the arc can propagate after triggering. The inner region is arranged between the two electrodes and is delimited axially by the end faces of the electrodes and is delimited longitudinally by the at least one expansion region.
