Abstract: The medium-wave air-cooled dummy load (50 kW as an example) is applied to the 528 medium-wave 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.

Key words: dummy load; air cooling; matching; Non-inductive resistance; maintain
