Fluid-tight wire feedthroughs

Abstract

The invention relates to a fluid-tight line feedthrough (1) for introducing an electrical conductor (2) into a high-pressure chamber, the line feedthrough comprising a housing (4) and a conductor (2). A ceramic insulator (3) is positioned between the housing (4) and the electrical conductor (2). The ceramic insulator (3) is divided into a first insulator section (7) facing the electrical conductor (2) and a second insulator section (8) facing the housing (4), thereby forming a conical separation plane (6), and a joint (9) made of electrically conductive material is positioned between said two segments (7, 8), said joint being connected to said two segments (7, 8) and to said the housing (4).

Description

technical field [0001] The invention relates to a fluid-tight wire feedthrough for introducing electrical conductors into a high-pressure chamber, the wire feedthrough having a housing and an electrical conductor passing through the housing. Background technique [0002] It is known from practice to supply a drive unit positioned in the pressure vessel with electrical energy by means of a fluid-tight line feedthrough passing through the wall of the pressure vessel. It is therefore common to transport natural gas by driving a compressor, for example by means of a drive motor positioned in a pressure vessel filled with natural gas, which is likewise arranged for compression and which in the process will pass through the Liquefaction of natural gas for transportation. For the drive motor, electrical energy must be introduced into the pressure vessel from the outside via electrical lines, and by means of fluid-tight line feedthroughs it can be ensured that natural gas cannot es...

Problems solved by technology

[0004] Although currently known wire feedthroughs ensure a somewhat fluid-tight feedthrough of electrical conductors into the high voltage chamber for supplying electrical energy to consumers located in the high voltage chamber, these wire feedthroughs has many disadvantages

[0005] The currently known fluid-tight wire feedthroughs therefore have the disadvantage that undesired electric component discharges or electrical breakdowns can occur which would impair operational safety

In addition, currently known fluid-tight wire feedthroughs may have the disadvantage that they allow gases (e.g. oxygen, hydrogen, helium, carbon dioxide, nitrogen, hydrocarbons, etc.) to a certain extent and trace gas) penetration, so the tightness of the wire feedthrough is limited

In addition, leaks may form through mechanical and thermal stress between individual components of the wire feedthrough

Furthermore, in the case of fluid-tight wire feedthroughs known from practice, there are problems when individual components of the wire feedthrough fail mechanically, e. enters the surrounding area like a bullet
