SEALED INPUT OF POWER ELECTRICAL CONDUCTORS THROUGH A PROTECTIVE SHELL Russian patent published in 2019 - IPC H02G3/22 

FIELD: electrical engineering.

SUBSTANCE: invention relates to the field of electrical engineering and electric power industry and, in particular, to the structures of power hermetic electrical inputs and can be used in various electrical and energy technology installations and apparatus, for example, at nuclear power plants. Device is designed to enter the power electrical circuits in sealed rooms or volumes with normal atmospheric pressure, for example, in the sealed zone of the containment of a nuclear power plant with any type of reactor. Sealed input of power electrical conductors through a protective sheath containing an internal sealing unit formed by combining two sealing sleeves in the input through a central metal pipe of the input case with a rigid current guide passing inside it, hermetically passing inside one or more centering couplings with its subsequent hermetic transmission through side dielectric pipes and composite bushing insulators, covered by a central dielectric pipe, which is the main fence of the main biological protection circuit, reinforced by common bushings input.

EFFECT: invention provides increased reliability and increased functionality of the electrical input.
