Abstract
A lightning protection method for a remote interconnected signal converter can effectively solves problems in conversion of high-speed interconnected signals of remote equipment in E1 network and protection of surge overvoltage of lines. The converter structurally comprises a balance signal interface circuit, a non-balance signal interface circuit and a signal conversion circuit, wherein the balance signal interface circuit and the non-balance signal interface circuit are respectively positioned on the front end face and the back end face of a case, and the signal conversion circuit is positioned inside the case. A two-stage lightning protection circuit formed by connecting a gas discharge tube, a decoupling resistor and a semiconductor discharge tube is added in the signal conversion circuit, non-balance signals received by the non-balance signal interface circuit are processed by the lightning protection circuit, and then are converted into balance signals by a network transformer, and the balance signals are output by the balance signal interface circuit finally. Once being damaged, interfaces can be changed by the unit of modules, and accordingly convenience in maintenance is achieved, and cost waste caused by changing the whole frame when only one interface is damaged is avoided.
