摘要： The invention relates to a device (1) which is used to protect electrical equipment against transient overvoltages, comprising (i) a spark gap having an intrinsic follow current interrupting capacity and (ii) an element (5) for improving the follow current interrupting power, which co-operates with the spark gap (2) such that the resulting follow current interrupting capacity of the protective device (1) is essentially greater than the aforementioned intrinsic capacity. The invention is characterised in that, when the equipment has a suspected short-circuit current that exceeds the intrinsic interrupting capacity of the spark gap (2), the improving element (5) comprises a means (6) for limiting the intensity of the electric current that can pass through the spark gap (2), said limiting means (6) being specifically designed and mounted in relation to the spark gap (2) in order to limit the intensity of the follow current, such that the follow current can be interrupted thanks to the intrinsic follow current interrupting capacity of the spark gap (2). The invention is suitable for overvoltage protection devices.

摘要： A lightning arrestor insulator is provided having a discharge gap portion and an arrestor ZnO element device (5) both in the body of the insulator, comprising opposed projecting discharge electrodes (3a,3b) arranged inside the insulator body. The discharge gap portion is formed of a heat resistant protrusion (2) inside the insulator body surrounding the discharge electrodes (3a,3b), and a pair of metal plates and/or electrically conductive ceramic plates (4a,4b) sandwiching the protrusion (2) from both sides thereof and electrically connected to the discharge electrodes. The pair of plates (4a,4b) are joined and airtightly sealed to the protrusion via an inorganic glass (10a,10b). The arrestor has a highly reliable airtight fixing and sealing structure so that accidental troubles in a power supply or distribution line at a normal working voltage can be substantially eliminated, and damage caused by hygromeration and lightning can be noticeably decreased.

摘要： Der für Gleichstrom-Freileitungen vorgesehen Ueberspannungsableiter besteht aus einer als offenes Funkenhornpaar (1, 2) ausgebildeten Funkenstrecke und aus mindestens einem mit der Funkenstrecke in Reihe geschalteten spannungsabhängigen Widerstand (3). Die Spannungsabhängigkeit des Widerstandes (3) ist durch die Gleichung: Strom = (Konstante x Spannungs)" beschrieben, wobei der Widerstand einen Exponenten von mindestens 20 aufweist. Der Ueberspannungsableiter ist besonders beeignet für die Oberleitung von elektrischen Bahnen.
