A plug-in plug-out series gap surge arrester device

Abstract

The application relates to the technical field of power transmission line protection equipment, and discloses a detachable series gap lightning arrester device which comprises a supporting frame, an insulation device, a wiring seat, a lightning arrester assembly and an elastic sheet. The supporting frame comprises a grounding support and a hook. The lightning arrester assembly comprises a lightning arrester body, a rotating rod and a limiting unit. One end of the lightning arrester body is in top pressing cooperation with the elastic sheet, and the other end is connected with the rotating rod. The rotating rod is hung and assembled on the hook. The limiting unit comprises a limiting rod, a limiting block and a locking assembly. The limiting rod is connected with the rotating rod. The hook is provided with a limiting groove. The limiting block has a first state of entering the limiting groove and a second state of turning out of the limiting groove. The locking assembly has a locking state of being rotationally matched with the hook along the circumference of the limiting rod and an unlocking state of being separated from the hook. When the locking assembly is in the locking state, the limiting rod cannot rotate around the rotating rod, and the lightning arrester body cannot independently reset and rotate, so that the risk of the lightning arrester body falling off is reduced.
