AC power frequency track circuit
- Experiment of Transformation on Power Frequency Track Circuit by Superimposing Closed Loop Code
- For three-phase AC power supply systems and locomotive converter complex and electric locomotives gradually tend to adopt a one-way AC power frequency.
- Intelligent AC power frequency cycle instrument
- It is unnecessary to use frequency conversion adjustment because it is designed with full digital press frequency tracking circuit and good adaptability.
- It is a special power supply equipment designed recently for phase sensitive track circuit in AC electrified railway.
