Introduction
Overview of the mutual matching criteria for the power-off and phase-splitting systems of rail transit trains
GB/T 36981—2018 standard mainly stipulates the technical requirements for the power-off and phase-splitting systems of passenger trains in $25~\mathrm{kV}, 50~\mathrm{Hz}$ AC electrified railways, and is applicable to lines with a maximum operating speed of no more than $350~\mathrm{km/h}$.
Comparison of Standard Frameworks
| Chapter Number | Content Overview | Keywords |
|---|---|---|
| 1 | Scope and Applicability | $25~\mathrm{kV},50~\mathrm{Hz}$AC Electrified Railway |
| 4 | General Principles and System Relevance | Traction Power Supply, Signaling System, Train Control Mode |
| 5 | Technical Requirements (Compatibility, Reliability, Operation) | Electric phase separation neutral section length, no-power section length |
| 6 | Control mode (automatic and manual) | Train control automatic, vehicle-mounted automatic, manual control |
Technical background and development
The core goal of the train power-off phase separation system is to ensure the safe operation of the train when passing through the no-power section. With the increase in the speed of high-speed rail, the traditional phase separation method can no longer meet the needs of high-speed operation, and articular electric phase separation and device electric phase separation have become the mainstream solutions.
Implementation suggestions and precautions
Case analysis: When designing a high-speed railway power-off over-phase system, the following factors need to be considered comprehensively:
- Train length matches pantograph spacing ($200~\mathrm{m}{\sim}215~\mathrm{m}$)
- Neutral section length setting ($380~450~\mathrm{m}$)
- De-energized section length (not less than double pantograph spacing, $L_{nz}{\sim}220~\mathrm{m}$)
