7. This should be a low voltage switch (380V?) Q1 single line circuit diagram, the switch rated current is 200A, with thermal relay and over-current quick break protection (I & gt& gt; If the external power supply is DC24 V, the switch also has the function of under voltage trip protection (UVT).
8. The peak value of sine wave voltage is U2 (effective value) which is twice the root. In the single-phase bridge rectifier circuit, there are two thyristors on each bridge arm, which bear the reverse voltage averagely, so the maximum bearing voltage of each thyristor is two times U2 of the root of two At (0~ α Interval:
the thyristors VT1 and vt4 bear positive pressure, but have no trigger pulse and are in the off state. Assuming that the circuit has been working in a stable state, then between 0 ～ α The thyristors vt2 and VT3 remain on e to the energy released by the inctor
2) ω t= α Time and after:
in ω t= α The thyristors VT1 and vt4 are triggered to make them turn on, and the current flows along the secondary winding a → VT1 → L → R → vt4 → B → tr → A. at this time, there is output voltage (UD = U2) and current on the load. The power supply voltage is reversely applied to the thyristors vt2 and VT3 to make them withstand the reverse voltage and turn off
3) π~π+α Interval:
when ω t= π When the power supply voltage is over zero, the inced potential makes the thyristors VT1 and vt4 continue to conct. When the voltage is negative half wave, the thyristors vt2 and VT3 are under positive voltage. Because there is no trigger pulse, vt2 and VT3 are in the off state
4) ω t= π+α Time and after:
in ω t= π+α The thyristors vt2 and VT3 are triggered to turn on, the current flows along the secondary winding of B → VT3 → L → R → vt2 → a → tr → B, the power supply voltage is applied to the load along the positive half cycle direction, and the load has output voltage (UD = - U2) and current. At this time, the power supply voltage is reversely applied to VT1 and vt4 to make them withstand the back voltage and turn off. The thyristors vt2 and VT3 have to be on until the next cycle ω t=2 π+α Until the thyristor VT1 and vt4 are triggered again.
