METHOD OF PREVENTION OF STATIC ELECTRICITY DISCHARGE FORMATION AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2008 - IPC H03F3/00 

FIELD: electricity.

SUBSTANCE: invention is related to the sphere of instrument making and may be used for protection against static electricity in different industries. Technical result is expansion of functional possibilities. In order to achieve this result prior to air supply to protected object it is affected by flow of alpha-particles. Then by permanent electric field of necessary index the laminar air flow is created and supplied in the premises to objects, on which the static electricity discharges may be created. In laminar flow the free electrons and air ions of required polarity are created. Ion concentration is brought to the value, which is necessary for prevention of static discharge. Device consists of ventilation unit, ionising chamber with source of alpha-particles, extracting air duct. In the chamber between the alpha-particles source and air duct across the air flow two mesh electrode are installed. For prevention of positive discharge of static electricity the first on the course of air flow the electrode is connected to the negative output of permanent voltage source, the positive output of which is grounded, and the second electrode is connected to the positive output of permanent voltage source.

EFFECT: manufacturing of device for protection against static electricity in different industries.
