DEVICE FOR CREATING A STABLE BIPOLAR CORONA DISCHARGE Russian patent published in 2021 - IPC H01T19/00 H05H1/48 

FIELD: electrical engineering.

SUBSTANCE: invention relates to the field of electrical engineering, in particular to devices for obtaining a corona discharge. The expected result is achieved by the fact that in a device for obtaining a corona discharge containing the main multi-polar electrodes connected to a high-voltage power source, and an auxiliary electrode, in order to increase the current and stability of a corona discharge, an isolated auxiliary corona electrode is made in the form of fan blades, the blades of the auxiliary electrode rotate to form a bipolar corona discharge in the gap between the auxiliary electrode and the multipolar electrodes made in the form of two halves of the side surface of the cylinder with an insulating gasket between them, and the rotation shaft of the auxiliary corona electrode is installed coaxially with respect to the cylinder formed by the multipolar electrodes. To stabilize the corona discharge and prevent its transition to a spark discharge, the blades of the auxiliary electrode are made of a material with a high electrical resistance.

EFFECT: increasing the stability of a bipolar discharge, increasing the discharge current, combining the functions of a fan and obtaining a bipolar discharge in one device makes it possible to manufacture powerful and compact devices for producing non-equilibrium plasma.
