Abstract

The clamp is attached in the form of movable clamping jaws and an opposite support (4) in geometrical form. The clamp is attached in its operating manner in medium voltage system at the voltage-conducting lead.

Description

In Trafostationen für Verteilertransformatoren sind dem Transformator und Kabelschleifen verschiedene Mittelspannungsschalter, bzw. Trenner vorgeschaltet die aus sicherheits- und funktionstechnischen Gründen in bestimmten Zeitabständen gewartet und betätigt werden müssen.In Transformer stations for Distribution transformers are the transformer and cable loops different medium voltage switch, or disconnector upstream for safety and functional reasons waited at certain intervals and pressed Need to become.

Bei Betätigung der Schalter erfolgt eine Unterbrechung der Stromversorgung für die angeschlossenen Verbraucher, um längere Versorgungsunterbrechungen zu vermeiden wird nach der Abschaltung eine Notstromversorgung aufgebaut. Nach Beendigung der Wartungs-, Reparaturarbeiten erfolgt eine erneute Versorgungsunterbrechung, um einen Rückbau der Notstromversorgung auszuführen.at activity the switch will interrupt the power supply for the connected Consumers to longer Supply interruptions will be avoided after shutdown built an emergency power supply. After completion of the maintenance, Repairs, a renewed supply interruption, for a deconstruction to run the emergency power supply.

Der im Patentanspruch 1 angegebenen Erfindung liegt das Problem zugrunde, dass durch die Vielzahl der geometrischen Formen der Leiter in Mittelspannungsanlagen mit der Möglichkeit zur Anbindung einer Umgehung nur mit größerem Aufwand eine Verbindung zwischen Einspeisepunkt und Umgehung hergestellt werden kann.Of the The invention defined in claim 1 is based on the problem that due to the multitude of geometric shapes of conductors in medium voltage installations with the possibility to connect a bypass only with great effort a connection between entry point and bypass can be made.

Dieses Problem wird durch die Formgebung der beweglichen Klemmbacken und des beweglichen Gegenhalter gelöst. Zur Anbindung Umgehung/Klemme wird am Gehäuse der Klemme eine Standartverbindung angebracht z. B. Kugelfestpunkt.This Problem is due to the shape of the movable jaws and solved the movable counter-holder. To connect the bypass / terminal, a standard connection is made to the housing of the terminal attached z. B. ball point.

Der mit der Erfindung erzielte Vorteil besteht darin, dass für verschiedene Leiterformen, rund, flach oder rund/flach kombiniert nur eine Klemme benötigt wird.Of the achieved with the invention advantage is that for different Ladder shapes, round, flat or round / flat combined only one clamp needed becomes.

Der im Patentanspruch 2 angegebenen Erfindung liegt das Problem zugrunde, dass vor einer Anbindung einer Notstromversorgung/Umgehung in einer Mittelspannungsanlage diese erst abgeschaltet werden muss und während der Abschaltung die angeschlossenen Verbraucher ohne Stromversorgung sind, desgleichen bei entfernen der Umgehung.Of the specified in claim 2 invention is based on the problem that before connecting an emergency power supply / bypass in one Medium voltage system this must first be switched off and during the Shutdown the connected consumers are without power supply, likewise when removing the bypass.

Dieses Problem wird dadurch gelöst, dass die Klemme ohne Abschaltung mit Hilfe einer handelsüblichen, geprüften Isolierstange an den spannungsführenden Leiter herangeführt wird und durch drehen der Spindel sich zuerst die Klemmbacken von zwei Seiten um den Leiter schließen, dann der Gegenhalter gegen den Leiter gepresst wird und so eine stromtragfähige Verbindung zum Leiter entsteht.This Problem is solved by that the terminal without shutdown using a commercial, tested Insulating rod to the live Head introduced and by turning the spindle first, the jaws of two Close sides around the ladder, then the counter-holder is pressed against the head and so a current carrying connection to the ladder arises.

Der Vorteil der Erfindung ergibt sich daraus, dass zum Anbringen einer Verbindung in Mittelspannungsanlagen zu Reparatur-, Wartungs- und Umbauzwecken keine Abschaltung notwendig ist und somit für die angeschlossenen Verbraucher keine Versorgungsunterbrechung stattfindet.Of the Advantage of the invention results from the fact that for attaching a Connection in medium voltage installations for repair, maintenance and repair Conversion purposes no shutdown is necessary and thus for the connected Consumer no supply interruption takes place.

Verwendungsbeispiele der Erfindung sind in der Zeichnung, 1–3 dargestellt und beschrieben.Examples of use of the invention are shown in the drawing, 1 - 3 shown and described.
