前言轨道电路的计算工作相当繁琐。近年来,由于计算手段和方法的革新,可用比较简便的方式进行。轨道电路的分析和计算,一般都是只讨论无分支的电路,然而在实际运用中,有分支的轨道电路(即道岔区段轨道电路)却占很大比重,因为计算过于复杂以及道岔区段的一次参数不易测定,所以甚少进行计算,工程和维修部门为确定其供电电压和校核其工作状态,通 Preface The calculation of the track circuit is quite tedious. In recent years, due to the innovation of calculation methods and methods, it can be carried out in a relatively simple way. The analysis and calculation of the track circuit generally only discuss the unbranched circuit. However, in practice, the branched track circuit (that is, the turnout section track circuit) accounts for a large proportion because the calculation is too complicated and the turnout section A parameter is not easy to measure, so very few calculations, engineering and maintenance departments to determine the supply voltage and check its working status, pass
