Embodiment

[0046] Such as Figure 1-Figure 2 As shown, the wiring of the surge protector in the home circuit, the circuit N is connected to the circuit meter N1, and the circuit L is connected to the circuit meter L1. After the circuit meter records the current consumption, the circuit meter N2 is connected to the leakage circuit breaker The leakage circuit breaker N3, the circuit meter L2 is connected to the leakage circuit breaker L3, and the leakage circuit breaker performs leakage protection for household appliances, and then the leakage circuit breaker N4 is connected to the surge protector N5, and the leakage circuit breaker L4 is connected to the surge protector L5. The circuit breaker is connected to the surge protector, and the surge alarm is electrically connected to the surge protector. When lightning strikes the home circuit, the surge protector will detect the lightning impact, that is, the instantaneous high current, which will cause the The surge arrester inside the surge ...

Abstract

The invention belongs to the technical field of surge protectors, and in particular relates to an alarm device for a power arrester, including a surge protector and a surge alarm, the surge protector is electrically connected to the surge alarm, and the surge alarm It includes a frame and a connecting frame. The connecting frame is installed on the left side of the rear of the frame. A connecting column is installed on the left side of the top of the frame. The left end of the connecting column is connected with a vertical shrapnel. The left part of the adsorption sheet is connected with a warped shrapnel, a conductive column is provided between the adsorption sheet and the frame, and a copper magnetic coil is installed on the conductive column, and the bottom of the adsorption sheet is also provided with a counter , the free end of the connecting frame is provided with an electric shock rod, and the electric shock rod is movably installed on the connecting frame through bolts. The advantage of the present invention is that the number of lightning strikes or overload voltages that the surge protector is subjected to is accurately recorded, so that maintenance personnel can Intuitively understand the overload impact of the 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...
