Embodiment Construction
[0021] The specific implementation manner will be further elaborated below in conjunction with the accompanying drawings.
[0022] Such as Figure 1a , Figure 1b As shown, the three-phase 18-pulse asymmetrical Y-shaped output winding phase-shifting rectifier device of the present invention includes a rectifier bridge and a three-phase 18-pulse asymmetrical Y-shaped output winding phase-shifting rectifier transformer. Wherein the three-phase 18-pulse asymmetrical Y-shaped output winding phase-shifting rectifier transformer includes primary windings, secondary windings and iron cores; the primary winding connection mode adopts delta connection, star connection, hexagonal connection or extended hexagonal connection; The rated voltage of the primary winding is low-voltage or high-voltage; the secondary winding is each phase with one long-side output winding with the same number of turns in each phase, symmetrical, and three mutually disconnected, and two output windings with the ...
