HIGH-VOLTAGE TRANSITION Russian patent published in 2021 - IPC H02G3/22 

FIELD: electrical engineering.

SUBSTANCE: invention relates to the field of electrical engineering, namely to the input of electrical conductors into a contaminated area. The high-voltage transition to the contaminated area through the metal wall of the protective structure contains a metal case hermetically installed in the wall with two insulating elements placed in it from the outer ends, between which there is a ceramic insulator installed in the axial channel of the case with a gap filled with glass solder, and an electrical conductor, which passes through insulating elements and is sealed with glass in an insulator. From the outer ends, both insulating elements are mated to the case, grooves are made on the seating surface of the case for installing O-rings in them. An annular groove is made on the inner surface of the case from the side of the glass solder entering gap, and an annular shoulder is made on the side of the solder exit from the gap. In the case the ceramic insulator soldering zone, a longitudinal annular groove is made, the inner diameter of which is related to the diameter of the axial channel of the case by a certain ratio.

EFFECT: increasing reliability of the transition.
