- Abstract
To solve the limitation of the current phase adjustment method of HF4-25 type protection box, this paper proposes a cross connection improvement method of 25 Hz phase-detecting track circuit phase adjustment. Firstly, this paper analyzes the limitation of the current phase adjustment method based on the working principle and its circuit impedance characteristics of the protection box. Then the detail of the proposed method is described, in which rationality is verified by means of theoretical analysis. Finally, the effectiveness of the proposed method is verified by simulation test and the field experiments.
