Abstract
The invention relates to a modular and compact arrangement (200) of three phases (A, B, C) of a gas-insulated apparatus (100), that is suitable for placement inside a tunnel or a pipe (106) or another confined space. According to the invention, the three phases (A, B, C) are arranged in a triangle or side-by-side on a fixation part (103, 104) which includes a roller system (105; 105a, 105b, 105c, 105d). This allows the insertion of such a three-phase assembly (100) into confined spaces such as pipes or tunnels (106), without the need for access by workers or machinery. Furthermore, the present disclosure relates to a method for assembling and installing such a three-phase arrangement (100) into the confined space (106).
Claims29
A gas-insulated line having a longitudinal axis, comprising phases with separately gas-tight single-phase enclosures that are aligned parallel to one another, and being segmented into line segments having a segment length, wherein at least one of the line segments comprises:
- at least one holding means arranged at at least one longitudinal position of the line segment for holding the single-phase enclosures of the line segment relative to one another,
- thereby mounting the single-phase enclosures of the line segment together and forming a unitary line-segment module, and
- the line-segment module comprises moving means for facilitating movement of the line-segment module, wherein the moving means comprise rollers for supporting and moving the line-segment module.
