Embodiment
Now in conjunction with the embodiments, the invention will be further described for accompanying drawing:
The embodiment of the present invention is by controller 1, power supply 2, ambiplasma exciter 3, emitter switch group 4, receiving pole switches set 5.Wherein power supply can adopt AC power, AC-DC coupling power supply, nanosecond power supply etc. various can the power supply of activated plasma.Plasma excitation 3 adopts bipolarity plasma excitation device.According to concrete user demand, exciter can be processed to various shape.Emitter switch group 4 receiving pole switches set 5 is made up of relay J and K switch.
Controller 1 is switched on or switched off by certain or certain the several relay controlled in emitter relay group 4 and receiving pole relay group 5, and corresponding emitter or receiving pole and excitation power supply 2 are connected.
1st relay of emitter switch group 4 and the 2nd relay of receiving pole switches set 5,1st switch of control emitter switch group 4 and receiving pole switches set 5 the 2nd switch are closed, between 1# emitter 7 to 2# receiving pole 8, now just defines the ambiplasma exciter of 2 grades.After emitter 7, now have suction airstream 9 produce an obvious suction peak, now exciter can form an obvious downward suction for air-flow, and this suction is proportional to applied voltage.
Then, the 1st switch of control emitter switch group 4 is closed, controls its 2nd switch simultaneously and close, disconnect receiving pole switches set 5 the 2nd switch, closed disconnection receiving pole switches set 5 the 3rd switch.This just defines the ambiplasma exciter of 2 grades between 2# emitter 10 and 3# receiving pole 12, and now the position at suction peak is moved to 2# emitter 10 position and produces suction airstream 11 at this, carries out downwards by that analogy.According to different demands, the ambiplasma exciter of 3 grades or multistage can be selected according to actual needs.
The suction peak position confined plasma exciter course of work is: controller 1 controls the switch of power supply 2, provides folding and disconnection are carried out in instruction control to emitter switch group 4 and receiving pole switches set 5 simultaneously.By upper switch and the lower position of the switch poor, ambiplasma exciter is formed at transmitting and receiving interpolar, along with switches set does not stop to change position, the position of activated plasma is constantly changing first, so just guide the continuous occurrence positions change in suction peak, form one group continuously to the suction peak of downstream movement at object plane.
