| Abstract: | The emergency self-propelled system is firstly applied in the Jingzhang high-speed intelligent EMU in our country.The emergency self-propelled system is composed of traction battery,bidirectional charger and UAS(an emergency self-propelled assisting installation).The functionality and relative technical parameters of each part were introduced.The working modes under five operations working conditions of the traction battery and bidirectional charger were analyzed.The initiating condition for air-conditioner emergency mode and emergency self-propelled mode,as well as the UAS stream of procedure under corresponding emergency mode was analyzed.The test construction of sample vehicles of Jingzhang highspeed intelligent EMU has been completed and the test showed stable specifications of the emergency self-propelled system. |
