论述了电气绝缘节的基本工作原理,说明无绝缘轨道电路绝缘节通过串并联谐振实现绝缘隔离的基本机理.其次阐述了轨道小轨道与主轨道电路之间的基本关系及缩短调谐区死区段的基本情况,同时针对铁路区间自动闭塞信号设备ZPW-2000A无绝缘轨道电路,在距电气绝缘节(调谐区)送电端第3个电容左右处地点,机车信号接收器收到的漏码信号达到最大值;第3个电容开路时,小轨道电路接收电压值下降最大等现象进行了理论研究,探寻上述现象的理论依据.
The basic working principle of the electrical insulation joint is discussed and the basic mechanism of isolation of the insulation section of the uninsulated track circuit through series-parallel resonance is described.Secondly, the basic relationship between the small orbit and the main track circuit and the dead zone , And at the same time aiming at the ZPW-2000A non-insulated track circuit of automatic block signal equipment in the railway section, the leakage signal received by the locomotive signal receiver at the place of the third capacitor from the power transmission end in the electrical insulation section (tuning area) Reaching the maximum value; the third capacitor open circuit, the small rail circuit receiving voltage drop the phenomenon of the largest theoretical study to explore the theoretical basis of the phenomenon.
