Spare Parts Of Generator Rotations Three-Phase Half-Bridge Module Model MXG/Y16-15

Working principle:

The working principle of bridge rectifier circuit is as follows: when e2 is positive half cycle, D1, D3 and direction voltage, D1, D3 conduction; Reverse voltage is applied to D2 and D4, and D2 and D4 are cut off. The circuit consists of e2, D1, Rfz and D3 power-on circuits. At Rfz, positive half-wave washing voltage is formed on the upper side and negative on the lower side. When e2 is negative half cycle, positive voltage is applied to D2 and D4, and D2 and D4 are switched on. Apply reverse voltage to D1 and D3. D1 and D3 are off. e2, D2Rfz and D4 are energized in the circuit, and another half wave of positive and negative rectifier voltage is formed on the Rfz. This is repeated and the result is a full wave rectifier voltage at the Rfz. The waveform diagram is the same as that of full wave rectifiCAT-parts-partsion. It is also not difficult to see from Figure 5-6 that the reverse voltage borne by each diode in the bridge circuit is equal to the maximum secondary voltage of the transformer, which is half less than that of the full-wave rectifier circuit. TR is a three-phase rectifier transformer, and its wiring group is Y/Y-12.VT1~VT6 is a thyristor element, and FU1~FU6 is a fast fuse. TS is a three-phase synchronous transformer whose wiring group adopts? /Y-11. The P end is the integrated six-pulse trigger circuit +24V power output end, which is connected to the pulse transformer primary winding connected to the common end. P1~P6 end is the output end of the collector of the integrated six-pulse trigger circuit power amplifier tube v1~v6, which are respectively connected to the other end of the primary winding of the pulse transformer. The UC terminal is the phase shift control voltage input terminal. The three-phase bridge semi-controlled rectifier circuit is basically the same as the three-phase bridge fully controlled rectifier circuit. Only the thyristor components of common anode group VT4, VT6 and VT2 are replaced by VD4, VD6 and VD2 rectifier diodes to form the three-phase bridge semi-controlled rectifier circuit.
