Drawbacks described above and problem, a kind of integrated low-voltage signal adapter in electric locomotive converter cabinet, the adapter are provided
For the signals such as low-tension supply and control to be transmitted in converter cabinet between traction control unit TCU and traction power module.
The utility model adopts the following technical scheme that realization: for the integrated low-voltage signal adapter in converter cabinet,
Including a signal converting circuit board, the input wiring terminal and traction control unit of signal converting circuit board control traction power module
Required lead is corresponding, and input wiring terminal becomes six groups through the switching of signal converting circuit board and controls the integrated of six power devices respectively
Harness, the output line terminal as signal converting circuit board.The adapter is connected to traction control unit TCU and traction in converter cabinet
Between power module, traction power module includes six power devices (i.e. IGBT).
The utility model distributes signal by signal converting circuit board, realize it is one-to-many, and by complicated circuit line
Integrated low voltage wiring harness is turned to, by simplifying circuit layout such a configuration reduce the quantity of cable, keeps layout succinct, section
