洪水淹没后中波发射系统的修复

Repair of Medium Wave Transmitting System after Flooding

2021年7月20日,郑州遭遇特大暴雨,洪水冲垮104中波发射台院区围墙,院内水深达2-3米,机房水深达1.4米,104台的657k Hz、603k Hz两部发射机被淹。灾后恢复重建过程中,104台技术人员在缺少资金投入、不能大范围更换设备的情况下,充分发挥主观能动性,克服各种困难,修复两部中波发射机,仅用3个月时间即恢复播出,这一过程中积累了大量处理泡水中波发射设备的经验。

On July 20,2021,Zhengzhou was hit by an extremely heavy rainstorm,and the flood washed down the enclosure of the 104 MW transmitter.The water depth in the hospital was 2-3 meters,and the depth of the machine room was 1.4 meters.The 657kHz and 603kHz transmitters of 104 were flooded.In the process of post-disaster recovery and reconstruction,104 technicians gave full play to their subjective initiative,overcame various difficulties,and repaired two medium-wave transmitters in the case of lack of capital investment and inability to replace equipment in a large range.It took only three months to resume broadcasting.In this process,they accumulated a lot of experience in dealing with underwater medium-wave transmission equipment.
