Fail safe surge arrester systems

Реферат: UNITED STATES PATENT APPLICATION OF CHARLES A. ROBERTS AND RAYMOND D. JONES FOR FAIL SAFE SURGE ARRESTER SYSTEMS ABSTRACT Laminar air gap devices include two overlapping con-ductive layers separated by a non-metallic insulating layer. The insulating layer is perforated to provide at least one air gap between the conductive layers. The devices are positioned between a line electrode and ground electrode of a gas filled surge arrester and resiliently retained thereon by conductive clips. Non-metallic fusible elements, preferably plastic, are interposed between the clip legs and the associated electrode. The fusible element may also be the insulating layer between the conductive layers.
