Project Description

High-voltage impulse track circuit device

The high voltage impulse track circuit device is used to detect the presence/absence status of the traction point in the AC 25,000 [V] train section and can be used not only in the AC train section but also in the non-train section.

  • It is a device that detects the presence or absence of trains, and it is possible that the related track circuit device and other conditions are in any condition.
  • 비 전철 구간뿐만 아니라 교류 전철 구간인 AC 25,000V 50/60Hz에서도 사용 가능한 장치로써 특히 복궤조 교류 전철 구간에서는 효율성이 크고 본 장치가 3Hz라는 특정 임펄스에 의해 동작되기 때문이다.
