Signal surge protector capable of automatically switching based on lightning early warning information and operation method

Abstract

The invention discloses a signal surge protector capable of automatically switching based on lightning early warning information and an operation method. The signal surge protector comprises a power supply module, an automatic switching control module, a switching switch module, a surge protection module, a signal transmission indication module, a surge protector working state indication module and a transmission signal compensation module, wherein the surge protection module is connected with the transmission compensation module and the surge protector working state indication module, an administrator management module issues a system starting handshake command signal handshake, and the automatic switching control module receiving the handshake signal is awakened, performs response handshake with the administrator management module once at regular intervals according to initial program setting, reports the zone bit number and the working state of the automatic switching control module, forwards the zone bit numbers and the working states of other control modules received by the automatic switching control module, and ensures stable construction of the communication bridge. The signal surge protector integrates the advantages of large through-flow, low residual voltage, no insertion loss, low standing-wave ratio, small error rate, no introduction of near-end crosstalk and the like.

Description

technical field [0001] The invention belongs to the technical field of lightning protection equipment, and in particular relates to a signal surge protector and an operation method for automatic switching based on lightning early warning information. Background technique [0002] Since the human society entered the information age, the requirements for the stability and reliability of information exchange have been increasing. At the same time, with the strengthening of people's awareness of lightning protection, the lightning protection requirements of modern electrical and electronic equipment have become more and more refined. The use of external direct lightning protection methods such as air terminals, down conductors, and grounding devices reduces the damage caused by direct lightning strikes. The ability of electromagnetic pulse has also been improved. However, due to its low voltage level and high integration, the signal system has poor maximum withstand impulse over...
