Abstract
Abstract A travelling switching block for a metallic encapsulated high-voltage switching installation wherein at or in a switching block housing there are assembled together into a metallic encapsulated insulated and transportable structural unit at least one input duct or throughpassage and one output duct or throughpassage as well as power- and/or disconnector switches and possibly additional quick grounders, voltage converters, current converters and work grounders. At least each duct or throughpassage which extends upwardly in operating position is pivotable by means of an insulating medium tight pivoting mechanism into a transport position producing a smaller transverse profile.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
216 words
A travelling switching block for metallic encapsulated high-voltage switching installations wherein to a switching block housing there are joined together into a metal encapsulated insulated and transportable structural unit at least one input duct and one output duct, the switching block being filled with insulating medium, the improvement comprising pivot means connecting each duct to the housing, each said duct extending upwardly in an operating position from the block housing and being movable by said pivot means into a transport position providing a small transverse profile, said pivot means including sealing means for sealing the respective duct against loss of insulating medium, each duct being supported by said pivot means such that in the transport position the duct is located at the lengthwise side of the switching block housing in the transport position, said pivot means further including a rotatable ring disk, and a stationary ring disk secured to the block housing and supporting the rotatable ring disk, said rotatable ring disk including a housing portion to which said duct is secured, each duct including an inner conductor, said switching block housing also including an inner conductor, and a coupling contact arranged in a pivot plane of said pivot means connecting the inner conductor of the duct with the inner conductor of the switching block housing.

A travelling switching block for metallic encapsulated high-voltage switching installations wherein to a switching block housing there are joined together into a metal encapsulated insulated and transportable structural unit at least one input duct and one output duct, the switching block being filled with insulating medium, the improvement comprising pivot means connecting each duct to the housing, each said duct extending upwardly in an operating position from the block housing and being movable by said pivot means into a transport position providing a small transverse profile, said pivot means including sealing means for sealing the respective duct against loss of insulating medium, each duct being supported by said pivot means such that in the transport position the duct is located at the lengthwise side of the switching block housing in the transport position, said pivot means further including a rotatable ring disk, and a stationary ring disk secured to the block housing and supporting the rotatable ring disk, said rotatable ring disk including a housing portion to which said duct is secured, each duct including an inner conductor, said switching block housing also including an inner conductor, and a coupling contact arranged in a pivot plane of said pivot means connecting the inner conductor of the duct with the inner conductor of the switching block housing.
Claim 3
Dependent Claim
45 words
The travelling switching block as defined in claim 1, wherein two pivotable ducts are provided, wherein both pivotable ducts are rocked in the transport position opposite one another and in the transport position the axes of the ducts are located essentially parallel to one another.
Claim 4
Dependent Claim
52 words
The travelling switching block as defined in claim 1, wherein two pivotable ducts are provided, wherein both of the pivotable ducts are pivotable in the same direction towards one another in the transport position and in the transport position the axes of the ducts extend essentially coaxially with respect to one another.
Claim 5
Dependent Claim
46 words
The travelling switching block as defined in claim 1 wherein said coupling contact consists of a ball at one conductor portion and a ball socket secured to another conductor portion, the ball having a center point located at the point of rotation of said pivot means.
Claim 6
Dependent Claim
73 words
The travelling switching block as defined in claim 4, wherein each pivotable duct of the block is laterally mounted on the switching block housing, a housing projection which laterally protrudes from the switching block, said stationary ring disk being secured to said housing projection, the pivot plane of said pivot means being vertical, said housing portion carried by the movable ring disk or the pivot means being constituted as a 90° bend member.
Claim 7
Dependent Claim
84 words
The travelling switching block as defined in claim 4, wherein each pivotable duct of the block is mounted at the top at the switching block housing, a housing projection arranged at the top at the switching block housing, said stationary ring disk being secured to said housing projection in such a way that the rotational axes which are perpendicular to the pivot plane are bisected by the angle between the duct axis in the operating position and the duct axis in the transport position.
Claim 8
Dependent Claim
82 words
The travelling switching block as defined in claim 6, wherein the coupling contact is coaxially arranged with the rotational axis and the conductor elements carrying the coupling contact transform an arcuate-shape into a straight intermediate conductor of the duct and into a linear conductor piece which connects the coupling contact with the inner conductor of the switching block housing, wherein the housing projection and the housing portion secured to the rotatable ring disk of the pivot means are curved in arc-shaped manner.
Claim 9
Dependent Claim
44 words
The travelling switching block as defined in claim 1, wherein the ring disks of the pivot means comprise threadable flanges which are released during pivoting of the duct and means for holding the flanges together during pivoting including a two-part ring with clamping means.
