The invention provides a shunting locomotive traction converter double-auxiliary power supply system and a fan starting method, in the system, a converter cooling fan is connected with an external electric load of a constant-frequency constant-voltage branch or a port of a garage power supply through a contactor, and is connected with an external electric load port of a variable-frequency variable-voltage branch through another contactor; when the locomotive is in a traction, braking or standby working condition, the converter cooling fan is disconnected with the constant-frequency and constant-voltage branch and is communicated with the variable-frequency and variable-voltage branch, and when the locomotive is in a garage charging working condition, the converter cooling fan is disconnected with the variable-frequency and variable-voltage branch and is intermittently communicated with the constant-frequency and constant-voltage branch. The invention has the technical effects of energy conservation and noise reduction.
本发明提供了一种调车机车牵引变流器双辅助供电系统和风机启动方法,在该系统中,变流器冷却风机通过一个接触器连接恒频恒压支路的外接用电负载或车库电源的端口,通过另一个接触器连接变频变压支路的外接用电负载的端口;当机车处在牵引、制动或待机的工况下时,变流器冷却风机与所述恒频恒压支路断开,并与变频变压支路连通,当机车处在车库充电的工况下时,变流器冷却风机与变频变压支路断开,并间歇式地与恒频恒压支路连通。本发明具有节能降噪的技术效果。
