摘要
介绍了微机保护装置工作中引起干扰的3个因素,包括干扰源、耦合途径和接收电路,并重点介绍了切断干扰耦合途径的措施,包括在装置中通过采用合理的接地形式、对电场和磁场加以屏蔽、采用滤波和退耦电路、采用逆变后的开关电源以及合理分配和布置插件等。实践证明这些措施可以有效地抑制干扰。
Three factors which cause interference in Protection system of microcomputer are interference sources, the routing and the circuit for receiving. This paper describes how to cut the router to reduce interference which includes suitable ground connection, shelter of electric and magnetic fields, use of wave filter and suppressing couple circuits, and arrangement of corresponding electric eguipmont. Practice has shown thats these methods are available..
