Structure of Pantograph
Design basis of segmented contact strip
Contact Mechanism: The pantograph is mounted on the roof of the train and equipped with a contact strip that presses against the overhead catenary wire. This ensures continuous electrical contact during operation.
Spring or Pneumatic Tension: The pantograph uses spring or pneumatic tension to maintain consistent pressure against the wire. This mechanism absorbs vibrations and ensures reliable contact, even at high speeds or during rapid accelerations and decelerations.
Current Collection: Electricity flows from the overhead wire through the pantograph and into the train's electrical system. This powers traction motors, lighting, air conditioning, and other onboard systems.
Self-Adjusting Feature: Modern pantographs are designed to adjust their height dynamically, compensating for variations in the catenary wire's height caused by terrain or installation tolerances.
The pantograph from Yonggui Electricis an essential component for electric vehicles, particularly in rail transit systems such as EV buses, trams, and high-speed trains. Its primary function is to transfer electricity from overhead lines to the train's electrical systems, enabling seamless operation without the need for onboard fuel sources.
