摘　　要：为提高 JZXC- 480型轨道电路一次调整的能力 ,提出改变轨道继电器返还系数的方法 ,并进行计算机仿真计算。结果表明可将返还系数从 5 0 %提高到 70 % ,大大提高一次调整范围 ,并能满足最恶劣的道床条件。A method for improving the ability of JZXC 480 track circuit once adjusting was presented. The method is to in crease the ratio of release voltage and work voltage of track relay. This method was simulated by computer. The results show that when the ratio is increased from 50% to 70%, the range of once adjusting track circuit is enlarged more.
