Description

Die Erfindung betrifft einen Isolierstützer gemäß dem Oberbegriff des Anspruchs 1.The invention relates to an insulation support according to the preamble of claim 1.

Ein derartiger Isolierstützer ist bereits bekannt (DE-GM 77 28 101). Hierbei handelt es sich um einen Innenraumstütziso­lator, bestehend aus einem Kopfteil und einem Fußteil sowie einem diese beiden Teile verbindenden Strunk, der mit mehreren im we­sentlichen gleichartigen, vorzugsweise symmetrischen Rippen ver­sehen ist. Dieser Stützisolator ist so konzipiert, daß er keine weiteren Funktionen erfüllen bzw. die hierfür erforderlichen Einrichtungen aufnehmen kann.Such an insulation support is already known (DE-GM 77 28 101). This is an interior support insulator consisting of a head part and a foot part as well as a trunk connecting these two parts, which is provided with a plurality of essentially identical, preferably symmetrical ribs. This post insulator is designed so that it can not perform any other functions or accommodate the facilities required for this.

Es stellt sich daher die Aufgabe, einen Isolierstützer der ein­gangs geschilderten Art weiterzuentwickeln, daß er neben seiner Stützfunktion gleichzeitig die Funktion eines induktiven Gebers für eine Überstromauslösung erfüllen kann.It is therefore the task of further developing an insulating support of the type described at the outset that, in addition to its supporting function, it can simultaneously perform the function of an inductive transmitter for overcurrent tripping.

Diese Aufgabe wird erfindungsgemäß durch die im Kennzeichen des Anspruchs 1 angegebene Kombination von Merkmalen gelöst.This object is achieved by the combination of features specified in the characterizing part of claim 1.

Die mit der Erfindung erzielten Vorteile bestehen darin, daß der für den induktiven Geber benötigte Platz in dem erfindungsge­mäßen Isolierstützer zur Verfügung gestellt wird, ohne dabei die Stützfunktion zu beeinträchtigen. Daher eignet sich der Einsatz dieses Isolierstützers vorteilhafterweise für kleinere Schalt­anlagen.The advantages achieved by the invention are that the space required for the inductive transmitter is made available in the insulation support according to the invention without impairing the support function. Therefore, the use of this insulation support is advantageously suitable for smaller switchgear.

Zweckmäßige Aus- und Weiterbildungen des Gegenstandes nach Anspruch 1 sind in den Unteransprüchen angegeben.Appropriate training and further developments of the subject matter according to claim 1 are specified in the subclaims.

So sind in den Unteransprüchen 2 und 3 Angaben enthalten, die sich allein auf den induktiven Geber im Isolierstützer bezie­hen. Im Anspruch 4 ist eine besondere Ausführungsform des Isolierstützers angegeben, der gleichzeitig aus kapa­zitiver Geber für die Messung der Betriebsspannung und als induktiver Geber für eine Überstromauslösung ausgebildet ist.For example, subclaims 2 and 3 contain information that relates solely to the inductive sensor in the insulation support. In claim 4, a special embodiment of the insulation support is specified, which is formed at the same time from a capacitive sensor for measuring the operating voltage and as an inductive sensor for overcurrent tripping.

Ausführungsbeispiele der Erfindung sind in Zeichnungen darge­stellt und werden im folgenden näher beschrieben.Embodiments of the invention are shown in drawings and are described in more detail below.

Es zeigen:

  • Fig. 1 einen Isolierstützer mit einem induktiven Geber, in Seitenansicht und teilweise im Schnitt
  • Fig. 2 diesen Isolierstützer mit einem induktiven und kapa­zitiven Geber, in Seitenansicht und teilweise im Schnitt.
Show it:
  • Fig. 1 an insulation support with an inductive sensor, in side view and partially in section
  • Fig. 2 this insulation support with an inductive and capacitive encoder, in side view and partially in section.

Nach Fig. 1 besteht der Isolierstützer aus einem Isolierkörper 1, in dessen Fuß eine axiale Bohrung 2 eingebracht ist. Diese Boh­rung dient der Aufnahme eine Befestigungsbuchse 3, die aus einem hochpermeablen Werkstoff besteht. Der Isolierstützer besitzt im Fuß einen hohlzylindrischen Raum, der von einer Spule 4 einge­nommen wird. Die Spule 4 und die Befestigungsbuchse 3 bilden zusammen den induktiven Geber. Die Spule ist über Anschlüsse 5 mit nachgeschalteten Funktionselementen verbunden. Im Kopf des Isolierkörpers ist eine weitere axiale Bohrung 6 eingebracht, die der Aufnahme einer Befestigungsbuchse 7 dient.1, the insulating support consists of an insulating body 1, in the foot of which an axial bore 2 is made. This bore serves to receive a mounting bush 3, which consists of a highly permeable material. The insulating support has a hollow cylindrical space in the foot, which is occupied by a coil 4. The coil 4 and the mounting bush 3 together form the inductive transmitter. The coil is connected via connections 5 to downstream functional elements. A further axial bore 6 is made in the head of the insulating body and serves to receive a fastening bushing 7.

Der Isolierkörper gemäß Fig. 2 weist noch die Besonderheit auf, daß die Bohrung 6 im Kopf des Isolierkörpers soweit eingebracht ist, daß die zugehörige Befestigungsbuchse 7 bis auf die Isolierdistanz A an die Befestigungsbuchse 3 herangebracht wird. Damit entsteht ein kapazitiver Geber, der über einen Anschluß 8 an weitere Funktionselemente angeschlossen ist. Mit Hilfe die­ses Isolierstützers läßt sich sowohl die Funktion des indukti­ven, als auch des kapazitiven Gebers erfüllen.2 still has the peculiarity that the bore 6 is made in the head of the insulating body so far that the associated mounting bushing 7 except for Isolation distance A is brought up to the mounting bush 3. This creates a capacitive encoder, which is connected via a connection 8 to other functional elements. With the help of this insulation support, both the function of the inductive and the capacitive encoder can be fulfilled.
