Embodiment Construction

[0028] figure 1 An embodiment of a transverse dismantling module 100 for a high-voltage switchgear is shown. The module comprises a housing 110 with three encapsulation sections 120 which are correspondingly designed to accommodate nominal conductor elements 150 . A nominal conductor element 150 is correspondingly arranged in the encapsulation section. The encapsulation sections each have a rigid first part 130 and a rigid second part 140 , which are connected to each other so as to be movable relative to each other in the nominal conductor direction, wherein the connection points are designed to be gas-tight. For example, an O-ring can be arranged at the connection point for a gas-tight seal. The three packaging sections 120 are connected to one another via connection elements 160 serving as gas channels to form a common gas chamber 180 . exist figure 1 In this case, the central encapsulation section is connected to the two outer encapsulation sections via connecting elem...

Abstract

The invention refers to a diagonal demounting module (100) for a high-pressure switchgear that has housing (110). The housing (110) comprises three enclosure sections (120) each having a primary rigid portion (130) and a secondary rigid portion (140) which are in nominal conductor direction movably connected to one another. Each enclosure section (120) is adapted to receive a nominal conductor element. The three variable length nominal conductor elements (150) are correspondingly arranged in the enclosure sections (120). The three enclosure sections (120) are connected with the connecting elements (160) to form a common gas space (180).

Description

technical field [0001] Embodiments of the invention relate to a gas-insulated switchgear, in particular for transmitting primary power in the high-voltage region. In particular, it relates to a lateral demountable module for such a switchgear. Background technique [0002] A gas-insulated switchgear (GIS) typically comprises a plurality of switches, which are electrically connected to one another via so-called busbars for transferring electrical primary power. Both single-phase encapsulated and multiphase-encapsulated busbars are known from the prior art. In the case of single-phase busbars, the primary conductors are arranged by means of an insulating gas in their respective encapsulation in the form of a metal-encapsulated housing. In contrast to single-phase encapsulated busbars, in multiphase (eg three-phase) encapsulated busbars the primary conductors of the different (eg three) electrical phases are arranged jointly in a single metal-encapsulated housing.
