MULTI-CHANNEL HIGH-VOLTAGE JUNCTION Russian patent published in 2022 - IPC H01B17/26 

FIELD: electrical engineering.

SUBSTANCE: invention relates to the field of electrical engineering, namely to means of transmitting power from one object to another, including sealed inputs of conductive elements, for example cables, into the hulls of ship structures or into a sealed chamber, into a multi-channel high-voltage junction to a contaminated area through a metal wall, in particular into the interior of a sealed explosion-proof container. A multi-channel high-voltage junction to the contaminated area through a metal wall of a protective structure contains a metal housing hermetically installed in the wall, into which at least one electrical conductor is inserted, part of the length soldered into an insulator. The insulator is hermetically fixed in the housing between two insulating elements through which an electrical conductor passes, and is made of glass-ceramic in the form of a glass plate with ceramic bushings baked into it on both sides, coupled with insulating elements. Grooves are made on the landing surface of the housing for installing sealing rings in them. One or more additional electrical conductors installed in the housing similarly are introduced into the housing in parallel to the electrical conductor independently of each other. The conductors are combined in pairs to form electric circuits independent of each other.

EFFECT: provision of multi-channel signal transmission while ensuring the noise immunity of the high-voltage junction and maintaining hermeticity and shock resistance.
