假负载在中波维护中的应用

Application of False Load in Medium Wave Maintenance

中波风冷假负载(以50 kW为例)应用于528中波发射台,该设备采用大功率无感电阻,满足使用功率要求,通过合理阻抗匹配,在设备维修、调试中使用,极大地减少了维护人员的工作量,提高了设备的容错率,在保障安全播出中起到关键作用。

The medium-wave air-cooled dummy load(50 kW as an example)is applied to the 528 mediumwave transmitting station.The equipment uses high-power non-inductive resistance to meet the use power.Through reasonable impedance matching,it is used in equipment maintenance and commissioning,which greatly reduces the workload of maintenance personnel staying up late,improves the fault tolerance rate of the equipment,and plays a key role in ensuring safe broadcasting.
