The birth of rail transit vehicles is based on the technical innovation of the steam engine and the official emergence of the railway. Its traction technology has gradually realized the transition and transformation from the steam engine to the internal combustion engine and then to the electric power. At present, the electric traction technology has become the core technology of urban rail transit vehicles.
The birth of rail transit vehicles is based on the technical innovation of the steam engine and the official emergence of the railway. Its traction technology has gradually realized the transition and transformation from the steam engine to the internal combustion engine and then to the electric power. At present, the electric traction technology has become the core technology of urban rail transit vehicles. The development of electric traction technology can be described as gradually transitioning from DC power supply in the 1880s to three-phase AC power supply in the early 20th century, and then to silicon controlled rectifier traction in the 1950s. The development process can be summarized as AC-DC drive traction, asynchronous traction, and AC drive traction.
The widely used AC drive traction currently has advantages such as high energy feedback efficiency, convenient traction control, simple bogie structure, good traction and braking effects, and complete anti slip and anti slip functions.
The development of rail transit in China started late, and the 6Y1 electric locomotive was not officially manufactured until 1958, while the development history of vehicle electric traction technology is basically consistent with the international development history. Today, the application of electric traction technology for urban rail transit vehicles is based on communication technology, control technology, and guarantee technology, comprehensively ensuring the safe and stable operation of the system, and coordinating the speed, control, and safety of urban rail transit vehicles.
