The utility model is by coiling winding and secondary winding in high-frequency magnetic, rely on the insulation property of secondary winding and Teflon high-voltage line, the insulativity triggering high-pressure thyristor needs can be met, do not need to carry out Phototube Coupling again, greatly simplifie the circuits for triggering of high-pressure thyristor.The utility model structure is simple, compact, and insulation property are high, good reliability, high degree reduce cost of manufacture.
Accompanying drawing explanation
Fig. 1 is the structural representation of embodiment 1.
Embodiment
Embodiment 1: as shown in Figure 1, a kind of pulse transformer being applicable to 3.3kV high-voltage soft-start, comprises high-frequency magnetic 1, high-frequency magnetic 1 is wound with a winding 2 and secondary winding 3.
The diameter of winding to be the number of turn be 1.5 circles is the high-temperature insulation wire of 0.51mm.The 19# Teflon high-voltage line of secondary winding to be the number of turn the be withstand voltage 20kV of 3 circles, the good insulation preformance of Teflon high-voltage line, does not need carrying out Phototube Coupling between input signal and output signal.
Wherein, high-frequency magnetic 1 is the high-frequency magnetic of 35mm*10mm*6mm.
Operation principle a: winding 2 connects the input pulse voltage of AC2V, secondary winding 3 obtains the voltage pulse output of AC4V under the effect of magnetic induction.Because secondary winding is Teflon high-voltage line, the insulating properties of self and resistance to pressure all can meet the insulativity requirement triggering high-pressure thyristor needs, do not need to carry out Phototube Coupling, simplify the circuits for triggering of high-pressure thyristor dramatically, reduce cost of manufacture.
Embodiment 2: a kind of pulse transformer being applicable to 3.3kV high-voltage soft-start, a described winding is wound in high-frequency magnetic clockwise, and secondary winding is wound in high-frequency magnetic clockwise, and all the other are all identical with embodiment 1.
Embodiment 3: a kind of pulse transformer being applicable to 3.3kV high-voltage soft-start, a described winding is wound in high-frequency magnetic counterclockwise, and secondary winding is wound in high-frequency magnetic counterclockwise, and all the other are all identical with embodiment 1.
