磁控管灯丝电源是医用直线加速器的重要组成部分，它是为磁控管灯丝提供加热功率的电源。磁控管灯丝电源是由电源部分、控制部分、故障报警部分3部分组成。该磁控管灯丝电源各参数在出厂前已调好，一般不需改动，一旦出现大的故障，恢复后应严格按照调试步骤进行调试，其常见故 The magnetron filament power supply is an important part of the medical linear accelerator. It is a power supply for the heating power of the magnetron filament. The magnetron filament power supply consists of a power supply section, a control section, and a fault alarm section. The magnetron filament power supply parameters have been adjusted before leaving the factory, generally do not need to be changed, once there is a major fault, after the recovery should be strictly in accordance with the commissioning steps for debugging, its common
