A Study on the location of Compensation Capacitor and Capacitance in the Concrete Slab Track
콘크리트 슬래브궤도에서 보상 커패시터의 위치 및 전기용량에 대한 연구
Abstract
Impedance of rails is increased by the magnetic coupling between rails and reinforcing bars in the concrete slab track. Currently, the current of track circuit has been compensated by installing the compensation capacitors on track circuit because of increasing the impedance of rails. In case of a rapid transit railway, the compensation capacitors are installed every 20[m] to compensate the current of track circuit in the concrete slab track. Because the interval of one block for a rapid transit railway is as long as 1500[m], the compensation capacitors are installed about the number of 70
