据司机反映:在列车运行速度达到150km/h时,无线列调设备有时会出现扬声器啸叫,话音不清楚。这种现象极有可能是由于电气干扰造成的,特别是提手柄瞬间纹波电压波动幅度较大,致使电气噪音窜入主机。虽然主机具有滤除干扰功能,但对此噪音反应不太灵敏,故设计了如图1所示的抗干扰电 According to the driver, when the train speed reaches 150km / h, the wireless alignment equipment sometimes has a loudspeaker howling and the voice is not clear. This phenomenon is most likely due to electrical interference caused, in particular, mention the instant handle ripple voltage fluctuations greater, resulting in electrical noise fleeing into the host. Although the host has a filter interference function, but the response to the noise is not very sensitive, it is designed as shown in Figure 1 anti-jamming
