2、时，轨道继电器（含一送多受的其中一个分支的轨道继电器）端电压：使用JRJC-66/345二元二位继电器时应不大于7V，使用JRJC1-70/240二元二位继电器时应不大于7.4V ，其前接点应该断开。用0.06标准分路电阻线在轨道电路送、受电端轨面上分路时，电子接收器（含一送多受的其中一个分支的电子接收器）的轨道接收端电压应不大于10V，输出端电压为0V，其执行继电器可靠落下。4、轨道电路送、受电端扼流变压器至钢轨的接线电阻不大于0.1。3V化25Hz相敏轨道电路钢轨引接线应采用等阻线。5、 轨道电路送、受电端轨道变压器至扼流变压器的接线电阻不大于0.3。6、 轨道继电器至轨道变压器间的电缆电

3、阻，3V化不大于150。7、 在电码化轨道区段，于机车入口端用0.06（国产移频）或0.15（UM71、ZPW2000）标准分路电阻线分路时，应满足动作机车信号的最小短路电流的要求。8、 凡装空扼流的轨道电路，不需要进行补偿措施，保持扼流变压器信号（次）侧开路。9、 防护盒原则上使用HF2-25型防护盒，维护规则与维规保持一致。10、 防雷补偿器维护规则与维规保持一致。11、3V化器材使用周期及寿命管理序号器材名称周期（年）寿命管理（年）备注1BE1（2）-F扼流变压器故障修15半年按照测试标准测试调谐器，超过标准则立即更换调谐器2BGT调谐轨道变压器故障修153HPT-ZD调相匹配盒故障修1

5、电压（Us、Uj）应按轨面清洁（生锈）状况参考调整表选取，选取原则为生锈（污浊）越严重，选取变比越小。2 所有送端变压器和受电端电抗变压器的变比均应按照参考调整表中的给出值选取。3 一送多受的轨道电路：在调整过程中主受与侧受继电器的压差不大于2.5V，若压差大于2.5V，可调整电抗变压器变比。4 调整表是按照特定参数计算、模拟实验及现场验证而得，轨道电路的实际情况和调整表有差异，本调整表只作为参考表。5 在现场模拟实验中，轨道模拟盘的最小轨道电路长度为100m。轨道电路要做到一次调整，一般应经历一次雨季（漏泄最大时）把轨道继电器端电压调整到不低于表中所列最小值（Ujmin），并确认翼片接触上止

6、轮；晴天后再检查轨道继电器端电压应小于表中所列最大值（Ujmax），且检查能否确保分路，如分路良好则该区段即能实现一次调整。23V化25Hz相敏轨道电路单元图见图1图133V化25Hz相敏轨道电路调整表一送一受无附加扼流变压器的轨道电路的调整表见表2至表6左侧；一送一受有附加扼流变压器轨道电路的调整表见表2至表6右侧；一送一受且设有一个无受电分支轨道电路的调整表见表7至表11左侧；一送一受设有无受电分支，且在该分支末端设附加扼流变压器轨道电路的调整表见表7至表11右侧。 一送一受且设有二个无受电分支轨道电路的调整表见表12至表16左侧；一送一受设有二个无受电分支，且在其中一个分支末端设附加扼流
