Plasma, the fuel factor evaporation generated using it and the drop and ice crystal that melt incoming flow and the attachment of driver surface, utilize it
The wave effect and shock effect of generation blow down and smash incoming flow and be attached to the drop and ice crystal on Plasma Actuator surface, and
Disturbance incoming air makes its entrained drip and ice crystal be not easy to impinge upon blade of wind-driven generator surface, and being finally reached prevents blade from covering
The effect of ice.When not needing to prevent icing, stop plasma electrical source power supply.
When blade of wind-driven generator abolishes icing demand, Plasma Actuator is covered by ice sheet at this time, open etc.
Gas ions power supply is that Plasma Actuator is powered by high pressure activation electrode 1, makes its start-up operation, high pressure activation electrode 1 and
First and second grounding electrodes form coupled electric field generation and ice sheet are crushed and are melted along face streamer-discahrge, due to depositing for water
More strong streamer-discahrge will be being generated, and be more readily formed at the zigzag that two surface electrodes occur in pairs along surface current
Light electric discharge, with the development along face streamer-discahrge, institute is melted and smashed to the fuel factor generated by it, wave effect and shock effect
The ice sheet of arrival forms empty gas and water and ice and the channel deposited, when channel connects high pressure activation electrode 1 and the second grounding electrode 4
When, spark discharge and along with more strong fuel factor, wave effect and shock effect will be generated, ice is finally smashed and loosen
Layer even takes the ice sheet of monolith attachment off.It abolishes icing and closes plasma power supply after the completion, stop power supply.
For the method effect that further description this patent proposes, the present embodiment selects the anti-broken polytetrafluoroethylene (PTFE) in laboratory
Icing experiment in surface carries out three electrode pulses along the explanation of the anti-broken insulating materials surface icing of face corona plasma, this reality
