ACTIVE LIGHTNING CONDUCTOR Russian patent published in 2012 - IPC H05F3/04 H02G13/00 

FIELD: electricity.

SUBSTANCE: invention relates to facilities of protection against damage of objects of various purpose under intense exposure to atmospheric electricity, namely, to facilities of lightning protection of buildings and structures. An active lightning conductor comprises a body with a cover, the following components connected electrically in series: an active lightning receiver, a generator of pulse voltage excited with a lightning-active charged external electric field, and a contact element of a grounding system. The generator comprises at least two charging resistor chains, and also a multi-section discharger arranged in the form of at least one capacitor-discharge circuit, made of serially alternating capacitors, each with two charging plates - covers with dischargers. Resistors of charging circuits are separated into two groups, resistors of one of them are connected with the upper plates-covers of capacitors, and resistors of the other - with the lower ones. Electromagnetic parameters of the lightning conductor provide for the possibility to charge capacitors from the external electric field under a critical lightning-active voltage of the latter to the level sufficient to generate and implement an anticipatory discharge with formation of a leader sent via a lightning receiver towards an impact leader of an external lightning. The lightning receiver is arranged in the form of a multi-rod crown with central and side rods. The lightning conductor is equipped with an external discharge circuit, made of pairs of current-conducting dischargers. Each discharger of one pair is electrically connected with one discharger of the other pair. One discharger of the upper pair is electrically connected with the lightning receiver, and one discharger of the lower pair - with a contact element of the grounding system. Dischargers of adjacent pairs are installed on the body with particular displacement in plan relative to the previous and/or subsequent pair of dischargers.

EFFECT: improved structural, process and operational properties of a lightning conductor, increased reliability of device operation and provision of higher protection of objects against damage with lightning strikes.
