Abstract

The invention relates to locomotive bogie control circuit technical field, and provides a bogie driving motor three-phase circuit especially. The bogie driving motor three-phase circuit comprises a line A, a line B and a line C. The bogie driving motor three-phase circuit changes original single phase alternating current power supply as three-phase alternative current power supply which is the same as three-phase power supply used in a workshop, thus imbalance with the three-phase power supply in the workshop is avoided, a total output capacity of a set is raised, a driving loaded capability is reinforced, and drive of the locomotive bogie is satisfied.

Description

technical field [0001] The invention relates to the technical field of locomotive bogie control circuits, in particular to a three-phase circuit of a bogie drive motor. Background technique [0002] The bogie of the Dongfeng 11G locomotive newly developed and manufactured by our company is specially made according to the situation of the locomotive. The existing unit is powered by a single-phase AC 220V power supply, which may easily cause the imbalance of the three-phase power supply in the workshop. The total output capacity of the power supply It is 25KVA and cannot drive the bogie of the new Dongfeng 11G locomotive, which affects production efficiency. Contents of the invention [0003] In order to overcome the deficiency that the existing bogie cannot rotate: the present invention provides a three-phase circuit of the bogie driving motor. [0004] The technical solution adopted by the present invention to solve the technical problem is: a bogie drive motor three-phas...
