JZXC-480型交流轨道电路是我国目前广泛使用的一种站内工频交流整流式轨道电路。至80年底,使用的数量为37384个区段,占区段总数的72％,占站内区段总数的78％,已用于1300多个车站。随着按装数量的不断增长,在现场实际使用中存在维修调整困难等问题,本文对此而进行了专题研究。本文首先导出单频一元轨道电路在任意钢轨阻抗,道碴漏阻时的调整,分路状态的计算公式,并对JZXC-480型交流轨道电路进行了全面分析计算。计算表明,分路状
JZXC-480-type AC track circuit is widely used in China now a station frequency AC rectifier track circuit. By the end of 1980, the number used was 37,384 sectors, accounting for 72% of the total number of stations and accounting for 78% of the total number of stations in the station, which had been used by more than 1,300 stations. With the increasing of the installed capacity, there are some problems such as the difficulty of maintenance and adjustment in the actual use in the field. This article has carried on the thematic research. In this paper, firstly, the formulas for calculating the adjustment of arbitrary rail impedance, the ballast leakage resistance and the shunting state of the single-frequency orbital track circuit are derived, and the JZXC-480 AC track circuit is fully analyzed and calculated. Calculation shows that the road shape
