Abstract

The invention discloses a surge protection device of an end-span method active Ethernet. An end-span method is adopted in the active Ethernet, and the active Ethernet comprises a network signal protection unit, an RJ45 input interface and an RJ45 output interface. The network signal protection unit comprises a first triode gas discharge tube, a second triode gas discharge tube, a first rectifier bridge, a second rectifier bridge, a first transient voltage suppressor, a second transient voltage suppressor, a first bidirectional transient voltage suppressor and a second bidirectional transient voltage suppressor. The surge protection device of the end-span method active Ethernet can be used for restraining lightning overvoltage formed by lightning electrostatic induction and electromagnetic induction for the active Ethernet with an intermediate span method adopted, lightning current energy is released to the ground, and it is ensured that the active Ethernet runs normally.

Description

technical field [0001] The invention belongs to the field of electric power equipment, and in particular relates to a surge protector for active Ethernet with end-spanning method. Background technique [0002] Lightning is a natural discharge phenomenon. The harm caused by lightning to communication facilities is mainly reflected in the electrostatic induction of lightning and electromagnetic induction of lightning. The lightning overvoltage formed by the electrostatic induction and electromagnetic induction of lightning is transmitted to the equipment terminal through the communication cable, causing The port on the device is damaged, causing a loss of communication. Active Ethernet is one of the commonly used network communications. [0003] Active Ethernet refers to the technology that can provide DC power supply for some IP-based terminals while transmitting data signals for some IP-based terminals without any changes to the existing Ethernet Cat. . The standard Categ...
