1.Electrical connection and protection
High voltage adaptation:
Supports DC 750V/1500V/3000V(common voltage for subway)or AC 25kV/50kV(trunk railway contact network voltage),and the specific requirements need to be confirmed according to the model.
Integrated high-voltage fuses,fast circuit breakers or lightning arresters to cut off fault current in milliseconds to prevent equipment from burning.
Signal control:
If it is a control loop component,it may contain digital input/output(DI/DO),which is used to transmit key information such as pantograph status and traction system ready signal.
2.Environmental adaptability
Vibration and shock resistance:
Through reinforced structure,shock-absorbing rubber and other designs,it can adapt to high-frequency vibration(5-200Hz)and impact(such as acceleration changes during train start/brake).
Wide temperature and protection:
The operating temperature range is-50℃~+90℃,meeting the operating needs of high-temperature deserts in Siberia or the Middle East.
Protection level IP68(dust-proof and waterproof),can be immersed in water for a short period of time(such as through water-stabilized sections)without damage.
3.Modularity and intelligence
Standardized interface:
It adopts ISO standard high-pressure connectors,threaded connections or quick plug-in interfaces for quick replacement or expansion and reduces downtime.
Self-diagnosis function:
Some models may integrate temperature sensors and current monitoring modules to upload status data in real time via CAN bus or Ethernet,supporting predictive maintenance.
