Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
As shown in Figure 1; The utility model comprises with the circuits for triggering of transformer output pulse: the input termination 220V AC power of diode rectifier bridge; The output termination filter circuit of diode rectifier bridge (first resistance R 1 is formed with diode D), first output of filter circuit connects the first transistor V through second resistance R 2

2Base stage.Transistor seconds V
2Collector current will be along with U
0DAnd change.Promptly changed the charging current of capacitor C.Thereby pass through U
0DVariation come effective control to the charging current of capacitor C.Under both actings in conjunction, a series of pulses of circuits for triggering control output.In order to increase the scope of shifting to, make main backflow voltage more stable.Require to increase commutating voltage, but too high voltages can make the breakdown damage of transistor unit again, so increase step-down current-limiting resistance Rs value.Originally the resistance at this place has only about several Europe, increase at present 150 Europe or more than, prevented that effectively trigger current is excessive, destroy output pulse signal, this method has improved the stability that triggers greatly.
The critical piece that influences the stability of control apparatus is exactly a thyristor, so will be from this parts approaches.The utility model is stable for the pulse voltage that guarantees thyristor is applied, so voltage stabilizing is partly changed to the relative trigger circuit pulse, its resistance is improved; Potentiometer resistance with circuits for triggering also progressively improves simultaneously.
The on-the-spot pulse control line (U2 outlet line) of the utility model changes Shielded Twisted Pair into by original normal signal line, and simultaneously, synchro source control line (220V incoming line) changes Shielded Twisted Pair into by original common electrical cable.
The utility model is avoided the stable of other power supply factor affecting synchro sources with increasing a dot interlace between synchro source and major loop and the transformer.
The utility model with might influence the control section of pulse signal, move to transformer room's control according to nearby principle, but not in production operation control room far away.
