MULTI-CHAMBER ARRESTER WITH GENERAL PRESSURE CHAMBER Russian patent published in 2017 - IPC H01T4/16 H02G13/00 H02H9/06 

FIELD: electricity.

SUBSTANCE: arrester comprises an insulating body (1) made of a dielectric material, and five or more electrodes (2), which are mechanically connected with the insulating body and spaced from the provision of the possibility of forming under the influence of a lightning overvoltage electric discharge between adjacent electrodes, the electrodes being arranged inside the insulating body and separated from the surface of the insulation layer. The nearby electrodes protrude into the discharge chamber (3), with exits to the surface of the insulating body. At least a portion of the discharge chambers is connected with at least one common pressure chamber via discharge gaps between adjacent electrodes.

EFFECT: invention of the arc discharge is extinguished after the passage of a pulse storm surge accompanying the transition to the current, which has commercial frequency, through zero, especially immediately after a lightning overvoltage impulse.
