Abstract
A turbogenerator (20) comprises a rotor (13) and a stator (14), which stator (14) has a polyphase winding, the terminals of which are arranged as generator terminals (U1, . . . ,W2) in a terminal arrangement (25) at the turbogenerator (20) to be connected to a neutral point (26) and to bus bar connections (S1, . . . ,S3). The terminal arrangement (25) is configured such that the phase sequence can be changed in a simple way by changing the connecting scheme at the terminal arrangement (25).
Claims8
A turbogenerator comprising:
- a rotor and a stator, which stator has a polyphase winding including terminals, the individual terminals of which are arranged as generator terminals in a terminal arrangement at the turbogenerator to be connected to a neutral point and to bus bar connections;
- wherein the terminal arrangement is pivotable at the neutral point and at the terminals such that the phase sequence can be changed after installation by changing the connecting scheme at the terminal arrangement;
- wherein each phase is assigned to a first generator terminal and to a second generator terminal, each of which corresponds to a first end and to a second end of the associated stator winding;
- and
- wherein said first and second generator terminals are arranged within the terminal arrangement consecutively in a continuous, alternating series.
A method for changing the phase sequence of a turbogenerator, the turbogenerator including a rotor and a stator, which stator has a polyphase winding including terminals, the individual terminals of which are arranged as generator terminals in a terminal arrangement at the turbo generator to be connected to a neutral point and to bus bar connections, wherein each phase is assigned to a first generator terminal and to a second generator terminal, each of which corresponds to a first end and to a second end of the associated stator winding, and wherein said first and second generator terminals are arranged within the terminal arrangement consecutively in a continuous, alternating series, the method comprising:
- changing the connecting scheme at the terminal arrangement after installation by pivoting the neutral point and terminals.
