link and saves locomotive traction converter cabinet direct current from B by four electric connectors of two-way Link power taking, A save locomotive traction converter cabinet and powered by 6 frequency-variable modules to 6 motors；Auxiliary circuit：B is saved locomotive supplementary AC system and powered with locomotive intermediate DC link；Will be middle straight by traction current transformation cabinet DC/AC modules Circulation is changed to three-phase alternating current, is then converted to variable-frequency variable-voltage power supply by an auxiliary converter module, there is provided to locomotive traction Ventilation blower, cooling fan motor；440V/60Hz three-phase alternating current is converted to by another auxiliary converter module, directly Supply 2 air compressor motors and air-conditioning；The accessory power supply of A section locomotives saves the three-phase alternating current of locomotive by three-phase electric connector from B, then passes through an auxiliary Become flow module and be converted to variable-frequency variable-voltage power supply, there is provided to 6 locomotive traction fan motors, oil/water blower fan of cooling tower electricity consumption；So 440V/60Hz alternating current is converted to by another auxiliary converter module afterwards, there is provided to air compressor motor, oil/water pump, main transformer Flow cabinet blower fan, air conditioning electricity.
- A kind of 10. high-power internal combustion-electric power dual power source main-line locomotive control method, it is characterised in that：During electric power operating mode：A section car pantographs take 25kV/50Hz alternating current from power network, and 970V/ is converted to by transformer 50Hz alternating current supply main convertor, is rectified into 1800V intermediate dcs electricity, part of direct current passes through by four-quadrant rectifier The alternating current that the inversion of this section Locomotive module is 1375V supplies traction electric machine traction and used, and another part direct current passes through Four cables of two-way save Locomotive Converter power transmission to B, and the inversion module that Locomotive Converter is saved by B is 6 tractions Motor is powered；During internal combustion operating mode：The diesel oil main generator of B section locomotives sends three-phase alternating current, by two rectifier rectifications into 1600V Intermediate dc electricity, part of direct current are changed into alternating current by this section locomotive inversion module and used for traction electric machine, one in addition Direct current is divided to save Locomotive Converter power transmission to A by cable, be changed into alternating current by the inversion module of A section locomotives leads for it Draw motor use.
