摘　　要：SWK-Ⅱ型平衡式短波天线交换开关主要应用于各短波广播发射台站,能够实现不同发射机与不同天线的连接交换,使发射机快速更换不同频段或不同方向的发射天线,达到理想的广播覆盖效果。实际工作中,由于天线交换开关频繁切换,其控制故障时有发生。以SWK-II型短波天线交换开关系统为例,简述开关的特点和控制原理,并对此类开关控制故障进行分析和总结,提出可行性解决方案,为同类型设备提供技术改造和故障处理思路。SWK-Ⅱtype balanced short-wave antenna switch is mainly used in short-wave broadcasting transmitting stations,which can realize the connection and exchange between different transmitters and different antennas,so that transmitters can quickly change transmitting antennas in different frequency bands or directions,and achieve ideal broadcast coverage.In practice,because of frequent switching of the antenna switch,its control faults often occur.Taking SWK-II short-wave antenna switch system as an example,the characteristics and control principle of the switch are briefly described,and the control faults of this kind of switch are analyzed and summarized,and a feasible solution is put forward,which provides technical transformation and fault treatment ideas for the same type of equipment.
