Abstract:
The invention relates to a housing for medium-voltage switchgears isolated from the cable vault via a base plate, the connection lines being guided through openings in the base plate, according to the preamble of patent claim 1. In order to design a housing for a medium-voltage switchgear for manufacture so as to obtain a pre-assembled arrangement which can easily be adapted or modified, according to the invention the base plate is divided into a plurality of segments, and the separation lines of the individual base plate segments extend centrally through the positions of the openings for the cables, and the openings are introduced into the base plate segments merely as perforated or pre-punched predetermined breaking lines.
Abstract:
The invention relates to gas-insulated medium-voltage switchgear with a busbar arrangement, comprising a plurality of switch panels wherein T-connection elements provide an electric connection between the busbar and the switch panel, according to the preamble of patent claim 1. In order to achieve here a more efficient use of the material in switchgear having a busbar arrangement, it is proposed according to the invention to adapt the T-connection elements in the area of the exit to the switch panel in the line cross-section only to the current capacity of the respective switch panel.
Abstract:
The invention relates to a medium voltage switchgear having disconnecting switches and three-position switches, according to the preamble of claim 1. In order to more easily make different implementations of the current-carrying capacity, according to the invention, the attainable current-carrying capacity is increased with respect to a base current-carrying capacity by means of the multiple arrangement of identical contact systems (1) per phase (L1, L2, L3) in a parallel arrangement on a common switch axis (2).
Abstract:
An encapsulated switchgear (2) designed be operated in an environmentally friendly manner and which at the same time allows for a very simple and cost-effective design. The switchgear (2) has a housing (4) defining an insulating space (6) and an electrical active part (8) arranged in the insulating space (6). The insulating space (6) has an insulation medium with a dielectric compound having a boiling point of above -25°C and being a fluoroketone having from 4 to 12 carbon atoms.
Abstract:
La presente invención se relaciona con un interruptor encapsulado que comprende un alojamiento (4) que define un espacio aislante (69 y una parte eléctrica activa (8, 9, 11a, 11b, 11c) dispuesto en el espacio aislante (6) , el espacio aislante (6) comprende un medio aislante. El interruptor se caracteriza porque el medio aislante comprende un compuesto dieléctrico que tiene un punto de ebullición superior a -25 oC.
Abstract:
The invention relates to a three-phase gasinsulated medium voltage switching device with a disconnecting device between medium voltage levels and voltage transformers with disconnector contacts which are arranged on a rotatable shaft, in that way, that by a partly rotation of the shaft, the disconnector contacts switch connected voltage transformers between medium voltage level and ground level. The shaft is passing through the side wall of a gastight compartment and/or a housing.
Abstract:
Die Erfindung betrifft eine gasisolierte Mittelspannungsschaltanlage mit Sammelschienenanordnung, mit einer Mehrzahl von Schaltfeldern, bei welchen T-Verbindungselemente eine elektrische Verbindung zwischen Sammelschiene und Schaltfeld bilden, gemäß Oberbegriff des Patentanspruches 1. Um hierbei zu erreichen, dass bei einer Schaltanlage mit Sammelschienenanordnung ein effizienterer Einsatz des Materials erreicht wird, ist erfindungsgemäß vorgeschlagen, dass die T-Verbindungselemente im Bereich des Abganges zum Schaltfeld im Leitungsquerschnitt lediglich auf die Stromtragfähigkeit des jeweiligen Schaltfeldes ausgelegt sind.
