摘要： The present invention relates to a lightning-protection spark gap, comprising: —a housing (G); —a first electrode (3a), which has a first outer face (Aa) and a first inner face (Ia); and —a second electrode (3b), which has a second outer face (Ab) and a second inner face (Ib); wherein the first electrode (3a) and the second electrode (3b) diverge from each other; wherein a striking region (Z) and an adjoining propagation region (L) for a spark are formed between the first inner face (Ia) of the first diverging electrode (3a) and the second inner face (Ib) of the second diverging electrode (3b); wherein the housing (G) forms an arc chamber (LK) between the first electrode (3a) and the second electrode (3b), which arc chamber is delimited by a quenching chamber (4); and wherein, in the housing (G), at least one first gas circulation channel (K1) is formed, by means of which a gas flow escaping from the quenching chamber (40) in the event of a lightning strike can be returned to the arc chamber (K) via at least one first cutout (V1; V1′; V1″; V1′″) in the propagation region (L) of the first electrode (3a). The first cutout (V1; V1′; V1″; V1′″) is asymmetrical with respect to a longitudinal extent of the first cutout (V1; V1′; V1″; V1′″) in the propagation direction of the arc; the first cutout (V1; V1′; V1″; V1′″) falls in the propagation direction of the arc from a first cross-section (Q1) of the first electrode (3a) to a minimum cross-section (QM) of the first electrode (3a) over a first distance (l1; l1′; l1″; l1′″) and rises from the minimum cross-section (QM) of the first electrode (3a) to a second cross-section (Q2) of the first electrode (3a) over a second distance (l2; l2′; l2″; l2′″). The first distance (l1; l1′; l1″; l1′″) is shorter than the second distance (l2; l2′; l2″; l2′″).

摘要： The invention relates to an arrangement for firing spark gaps with a trigger electrode which is located at or in one of the main electrodes and which is insulated from this main electrode, wherein the trigger electrode can be electrically connected to a further main electrode via at least one voltage-switching or voltage-monitoring element and there is an air gap between the trigger electrode and the further main electrode, wherein the trigger electrode forms a sandwich structure with an insulating layer and a layer made of a material with lower conductivity than the material of one of the main electrodes. Moreover, the insulating layer is designed as a thin foil or lacquer layer and the layer made of the material of lower conductivity is in contact with one of the main electrodes or rests on it. According to the invention, for discharging energetically weak overvoltage events without response of the spark gap formed between the main electrodes, the insulating layer of the sandwich structure is interrupted outside the firing area and/or an electrical component which influences the response behavior is connected between the trigger electrode and the associated main electrode.

摘要： A surge protection device comprises at least one disconnecting device provided in a housing, a heat-conducting element, an actuating element for actuating an indicating device, and a locking element, the heat-conducting element being in contact with the housing. The actuating element is fastened to the heat-conducting element by means of the locking element, and the fastening is configured such that when a predetermined temperature at the locking element is exceeded, the locking element is detached from the heat-conducting element and/or from the actuating element and releases the actuating element.

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.
