Power supply lightning arrester alarm device

Abstract

The invention belongs to the technical field of surge protectors, and relates to a power supply lightning arrester alarm device. The device comprises a surge protector and a surge alarm; the surge protector is electrically connected with the surge alarm; the surge alarm comprises a rack and a connecting frame; the connecting frame is installed on the left side of the rear portion of the rack; a connecting column is installed on the left portion of the top end of the rack; a vertical elastic piece is connected to the left end of the connecting column; an adsorption piece is arranged at the lower end of the vertical elastic piece; a warping elastic piece is connected to the left portion of the adsorption piece; a conductive column is arranged between the adsorption piece and the rack; a copper magnetic ring is installed on the conductive column; a counter is arranged at the bottom of the adsorption piece; an electric shock rod is arranged at the free end of the connecting frame; and the electric shock rod is movably mounted in the connecting frame through a bolt. According to the Power supply lightning arrester alarm device, the frequency of lightning stroke or overload voltage borne by the surge protector can be accurately recorded, and maintenance personnel can visually know overload impact borne by a circuit.

Description

technical field [0001] The invention belongs to the technical field of surge protectors, and in particular relates to an alarm device for a power surge arrester. Background technique [0002] Lightning protection includes external lightning protection and internal lightning protection. External lightning protection is mainly based on lightning receptors (lightning rods, lightning protection nets, lightning protection belts, lightning protection lines), down conductors, and grounding devices. Protected from direct lightning strikes, the lightning that may hit buildings is discharged into the ground through lightning rods (belts, nets, lines), down conductors, etc. Internal lightning protection includes measures against lightning induction, line surge, ground potential counterattack, lightning wave intrusion, and electromagnetic and electrostatic induction. This method adopts equipotential bonding, including direct connection and indirect connection through SPD, so that the m...
