摘　　要：本文研究了PC级双电源自动转换开关在进行电源切换工作时发射机工作状态的变化情况,旨在完善广播电视发射系统建设方案和提高系统稳定性。通过测试广播电视发射台站的多种常用型号发射机在PC级双电源自动转换开关自动切换和手动切换主备电源情况下是否掉功率和自恢复时长等数据,展示了电源切换速度对于发射机是否停播以及恢复播出时长的影响,并提出一些关于发射系统建设的建议。This paper studies the changes in the working state of the transmitter during the switching of the power supply with the power control level automatic transfer switching equipment,aiming to improve the construction scheme of the radio and television transmission system and improve the stability of the system.By testing the data of power loss and self-recovery time of various commonly used transmitters when using the power control level automatic transfer switching equipment automatically and manually switching from primary to secondary power supply.This study demonstrates the impact of power switching speed on whether the transmitter stops broadcasting and the duration of resuming broadcasting and proposes some suggestions for the construction of the transmission system.

关 键 词：双电源自动转换开关 发射机 自恢复时间 系统建设
