| (54) | AN ANTI-TIP ELECTRODE TYPE SINGLE ELECTRODE STRUCTURE AND ELECTRODE CLEANING DEVICE |
| (57) The present invention relates to the technical field of plasma cleaning, and provides
a point-discharge prevention unipolar electrode structure and a plasma cleaning device.
The point-discharge prevention unipolar electrode structure comprises a dielectric-barrier-free
electrode assembly, an insulation groove body, and a high-voltage conductive assembly.
The dielectric-barrier-free electrode assembly comprises two de-pointed electrodes,
the two de-pointed electrodes are arranged opposite to each other and form an electrode
space, both the two de-pointed electrodes are embedded in a groove of the insulation
groove body, both the two de-pointed electrodes are electrically connected to the
high-voltage conductive assembly, and both the two de-pointed electrodes have a point-discharge
prevention property, thereby preventing the triggering of a unipolar corona near the
two de-pointed electrodes, and helping to suppress the arc light caused by the tipped
electrodes. Therefore, the electrode space has the property of extending the discharge
space, which supports extending the discharge space on the basis of enhancing the
electric field strength, breaks through the restraint of suppressing the arc light
caused by the point electrode by using the insulating dielectric barrier layer, and
helps to get rid of the restriction of the insulating dielectric barrier layer to
the discharge space.
