Subway vehicle traction control device VVVF inverter, SIV auxiliary power supply device with heat pipe radiator

  Variable voltage (VVVF) has a steady state control characteristics, and has good dynamic performance, can be comparable with the DC speed control system, widely used in rail transit locomotive traction and speed control system. However, with the increase in inverter power, its heat is also a substantial increase in the stability of the inverter to become an important factor in the use of stability. Heat pipe radiator because of its efficient and reliable cooling capacity, in the locomotive traction and speed control system of cooling applications in the obvious advantages, more and more people of all ages.

  Our company for the subway vehicle development of the traction control device VVVF inverter, SIV auxiliary power supply device with heat pipe radiator has been successfully applied: Shanghai 6,8 line; Xi'an 1,2,3,4 line; Beijing Line 5. Russia St. Petersburg Metro, Budapest, Hungary, Ho Chi Minh City, Vietnam Metro and other projects
