模块局的安全防护与电磁兼容性研究

Security Protection of Module Station and Electromagnetic Compatibility Study

依据EMC(Electromagnetic Compatibility)的基本理论,针对我国通信网中远端模块局大多设在农村乡镇且安全防护功能差的现状,构建了模块局通信运营过程中的安全管理模型。在进行大量调查研究的基础上,依据IEC61643-1(GB18802.1)的性能要求和试验方法,运用SPD(Surge Protective Devices)+MCB(Minia-ture Circuit Breaker)组合方案,实现了多级保护方案设计。并针对瞬态干扰抑制中接地系统的机房环境、土壤取样和接地方式提出了切实可行的管理措施。极大地提高了通信系统中模块局的可靠性和安全性。

Based on EMC （ Electromagnetic Compatibility） basic theory, in view of the communications network in remote modules are mostly located in the township and poor security features, the module was constructed in the communication operators in the process of safety management model. Based on IEC61643-1 （GB18802. 1 ） of performance requirements and test methods, the use of SPD （Surge Protective Devices） ＋ MCB （Miniature Circuit Breaker） package, to achieve a multi-level protection programme design. And for transient interference suppression in the grounding system in the engine room environment, soil sampling and grounding to choose a practical management measures. Greatly improve the communication system in the module＇s reliability and security.
