摘    要:在 DJ 型交直交电力机车上安装400kHz 感应电台后,电台运用不良。原因在于 DJ 型电力机车受电弓对接触网上的传输信号有旁路作用,同时机车的高压供电回路产生的交流谐波分量很多,因而产生较大的干扰信号,对感应电台产生的有用信号有较强的干扰所致。经改造,在供电回路加装400kHz 信号阻波器后,电台使用正常。

关 键 词:机车  电台  运用

Abstract:Transmitter-receiver's operation becomes poor after 400KHZ inductive transmitter-receiver is mounted on DJ AC-DC-AC electric locomotive due to a bypassing effect of pantograph of DJ electric locomotive on transmitting signal from catenary and too much AC harmonic heft produced by high voltage power supply circuit of locomotive, which causes a bigger interfering signal,and a stronger interference against the useful signal produced by inductive transmitter-receiver.And transmitter-receiver restores its operation when 400KHZ signal block filter is added on power supply circuit.
Keywords:Locomotive  Transmitter-receiver  Application
