一、UM-71型电气分隔点轨道电路(简称UM71型)设备概况:无绝缘轨道电路是六十年代前后发展起来的一种新型轨道电路。电气分隔点轨道电路就是无绝缘轨道电路的一种。由于它不需要绝缘节,尤其在电气化区段可以取消阻抗连接器,这样,不仅便于维修,而且在经济上也有重大意义;它还具有自由选择闭塞分区长度、设备集中 A, UM-71-type electrical separation point track circuit (referred to as UM71 type) Equipment Overview: Uninsulated track circuit is developed around the 1960s a new type of track circuit. Electrical separation point track circuit is a non-insulated track circuit. Since it does not require an insulation joint, the impedance connector can be eliminated especially in the electrification section, which is not only easy to maintain but also economically significant. It also has the freedom to choose the length of the blocking partition and the concentration of equipment
