Socket type surge protection device integrating decoupler, lightning protection and power output socket

Abstract

The utility model discloses a socket type surge protection device integrating a decoupler, lightning protection and a power supply output socket, and belongs to a lightning arrester. The device comprises a shell, a power line is arranged on the shell, and the power line is sequentially connected with a power switch, a current overload protector and a decoupler in series, then connected to an anti-surge circuit board and then connected with a power output socket. The surge-proof circuit board adopts a multi-stage protection circuit, the first-stage protection circuit comprises a decoupler, the rear end of the decoupler is connected with at least two stages of discharge loops in parallel, and each discharge loop comprises a piezoresistor and a gas discharge tube. According to the utility model, the inductive reactance of the power line is increased, the insufficient length of the power line is made up, the cooperation between the socket type surge protection device and the previous stage surge protection device is coordinated, and overvoltage and overcurrent generated by mismatching of energy of the multi-stage power supply surge protection device or other reasons in the live line and the zero line are filtered by using the piezoresistor and the gas discharge tube. And electric equipment is effectively protected from being interfered and damaged by thunder and lightning and other magnetic fields, electric fields and the like.
