摘　　要：本安防爆电话耦合器是连接交换机与本安电话机的通迅设备,它把交换机送来的非本安信号送给本安电话机,实现安全场所对危险场所的生产调度和通讯。该耦合器电路结构简单,元件少,成本低,参数选择合理,可连续调节限定电流,能适应负载和电源电压的变化,具有性能良好、工作可靠、实现容易等优点。The intrinsically- safe explosion -proof phone coupler link up the communication between the swithboard and the phone. The coupler transmitted information from non - safety swithboard to the intrinsically - safe phone. The coupler has merit such as simple structural, less component, lower cost, proper parameters, serial setting the currents, applicable to various the loads and power voltages. The coupler has advantages of performance better, reliable and easier realization.
