Zusammenfassung:The utility model discloses a main transformer switching device of a traction substation based on a DSP. The device comprises a mainboard CPU plug-in, an AC interface plug-in, a switching value input plug-in, a switching value output plug-in, and a communication plug-in. The AC interface plug-in and the switching value input plug-in are connected with the mainboard CPU plug-in through an input end signal processing circuit, and meanwhile the mainboard CPU plug-in drives an exit relay, a disconnecting switch and an earthing knife-switch in the output plug-in through an output end signal processing circuit. The exit relay controls switching operation of the transformer. The mainboard CPU plug-in is also connected with an input and change-over switch and a man-machine interaction interface module.
