RS-232端口光电隔离型电涌保护器
Optical isolation and surge protection of RS-232 port
摘要
Abstract
Lightning over-voltages are the important reasons for losses in communication port, which make it neces-sary and urgent to study into the lightning protection of communication port. According to the protection characteris-tics of gas discharge tube and transient voltage suppressor, the decoupling components are selected carefully to a-chieve the rational energy correspondence between multi-level SPD. Besides that,optical design is also considered to design protective circuit of RS-232 port. Finally,in order to verify the design scheme,the lightning impact platform called LST-6 kV/3 kA and ICGS and function generator called DF1641C are employed for the experiments. The ex-periments show that bearing capacity of lightning over-voltage of communication port RS-232 has been greatly im-proved and will not produce insertion loss to original circuit by adding the protection circuit.关键词
