Equipment and method for rapidly screening electrical aging state of power cable insulating layer

Abstract

The invention belongs to the technical field of cables, and particularly relates to a power cable insulation layer electrical aging state rapid screening device and method.The power cable insulation layer electrical aging state rapid screening device comprises a base, a mounting frame is fixedly connected to the upper surface of the base, a through hole is formed in the inner wall of the mounting frame, a threading frame is fixedly connected to the hole wall of the through hole, and a threading hole is formed in the inner wall of the threading frame; two symmetrical mounting plates are fixedly connected to the upper surface of the mounting frame, and screening mechanisms are arranged on the inner walls of the mounting plates. According to the invention, when one surface of the cable insulation layer is screened out to be abnormal and the insulation layer is limited, the insulation resistance tester and the probe can be used for screening the interior of the insulation layer, so that the state of electrical aging in the insulation layer can be screened out in time, and electric field distortion at the defect of the insulation layer caused by inaccurate screening is prevented; the subsequent operation of the cable is prevented from being threatened, and the screening efficiency of the cable insulation layer electrical aging state screening equipment is improved.
