The invention discloses a non-insulated frequency shift track circuit and an insulating joint for automatic blocking thereof, and the insulating joint for non-insulated frequency shift automatic blocking comprises a resonance unit, a first traction balance unit and a second traction balance unit. The resonance unit, the first traction balance unit and the second traction balance unit are connected in parallel in the track circuit between two adjacent sections, the first traction balance unit comprises a second capacitor and a second inductor which are connected in series, and the second traction balance unit comprises a third capacitor and a third inductor which are connected in series. In the scheme, cross-zone transmission of frequency shift signals of track circuits in adjacent sections is conveniently prevented through the resonance units, traction backflow between two steel rails is conveniently balanced through the traction balance units, the number of the traction balance units is two, and in this way, the traction backflow can be further optimized to keep balance; and the scheme also has the characteristics of simple structure, obvious effect, convenience in popularization and the like.
本发明公开了一种无绝缘移频轨道电路及其自动闭塞用绝缘节,其中,无绝缘移频自动闭塞用绝缘节包括:谐振单元和第一牵引平衡单元和第二牵引平衡单元;谐振单元、第一牵引平衡单元与第二牵引平衡单元并联在相邻两个区段之间的轨道电路,且第一牵引平衡单元包括:串联的第二电容器和第二电感器,第二牵引平衡单元包括:串联的第三电容器和第三电感器。在本方案中,通过谐振单元以便于防止相邻区段轨道电路移频信号越区传输,通过牵引平衡单元以便于平衡两钢轨间的牵引回流,而且牵引平衡单元的数量为两个,本方案如此一来,则可进一步优化牵引回流保持平衡功能;并且本方案还具有结构简单,效果显著和便于推广等特点。
