Description
Sternpunkt für mehrere Leitungen, insbesondere für eine dreiphasige Erdungsvorrichtung Die Erfindung betrifft einen Sternpunkt für mehrere Leitungen, insbesondere für eine dreiphasige Erdungsvorrichtung, mit mehreren miteinander verbundenen Kabelschuhen. Durch einen solchen Sternpunkt werden vorzugsweise die drei zu den zu erdenden Phasen führenden Leitungen und die zur Erde führende Leitung vereinigt. Mit einer solchen Erdungsvorrichtung werden somit die drei Phasen einer Starkstromleitung kurzgeschlossen und geerdet.Star point for several lines, especially for a three-phase one Grounding device The invention relates to a star point for several lines, especially for a three-phase grounding device, with several interconnected Cable lugs. Such a star point preferably turns the three into the Lines leading to earthed phases and the line leading to earth are combined. With such a grounding device, the three phases of a power line are thus established short-circuited and grounded.
Bei den im Betrieb auftretenden starken Beanspruchungen kommt es vor, daß die Kabelschuhe sich zueinander verdrehen, wodurch ihre durch den Abstand der Phasenleiter gegebene winkelgerechte Stellung nicht mehr beibehalten wird und sogar die die Kabelschuhe gegebenenfalls zusammenhaltende Schraube gelockert wird.In the case of the heavy loads occurring in operation, it happens that the cable lugs twist to each other, whereby their by the distance of the Phase conductor given angular position is no longer maintained and even the screw holding the cable lugs together is loosened.
Zur Vermeidung dieses Nachteils schlägt die Erfindung vor, daß die Löcher der Kabelschuhösen mit gezahnten Rändern versehen sind und daß ein Zylinderstück vorgesehen ist, dessen Außenumfang mit in Längsrichtung verlaufenden Zähnen versehen ist, die in die Zähne der Ränder der Löcher der Kabelschuhösen gleitend passen. Die Kabelschuhe können durch eine Schraube zusammengehalten sein, wobei gemäß der weiteren Erfindung das Zylinderstück als eine die Schraube umgebende Hülse ausgebildet ist. Durch diese Ausbildung wird erreicht, daß die über die Hülse geschobenen Kabelschuhe sich in ihrer Winkelstellung zueinander nicht mehr verschieben können. Die Schraube hält nur mehr die Kabelschuhe zusammen, d. h., sie wird nicht auf Drehung beansprucht, wodurch ein Lösen verhindert wird.To avoid this disadvantage, the invention proposes that the Holes of the cable lug eyes are provided with serrated edges and that a cylinder piece is provided, the outer circumference of which is provided with teeth running in the longitudinal direction which slide into the teeth of the edges of the holes of the cable lug eyes. The cable lugs can be held together by a screw, wherein according to FIG Another invention, the cylinder piece is designed as a sleeve surrounding the screw is. This design ensures that the cable lugs pushed over the sleeve can no longer move in their angular position to each other. The screw only holds the cable lugs together, d. i.e., it is not subject to rotation, thereby preventing loosening.
Durch die Vielzahl der Zähne an der Hülse und an den Rändern der Löcher der Kabelschuhösen ist es möglich, die Stellung der Kabelschuhe zueinander auch um kleine Winkel zu ändern.Due to the multitude of teeth on the sleeve and on the edges of the holes With the cable lug eyes it is possible to change the position of the cable lugs in relation to one another to change small angles.
Eine beispielhafte Ausführungsform der Erfindung ist in der Zeichnung dargestellt, und zwar ist F i g. 1 eine Aufsicht auf den Sternpunkt, wobei der Schraubenkopf und die Unterlagsscheibe weggelassen sind, F i g. 2 ein Schnitt durch den Sternpunkt nach der Linie II-II der F i g. 1 und F i g. 3 eine vergrößerte Stirnansicht der Hülse. Der Sternpunkt weist die vier Kabelschuhe 1 bis 4 auf, von denen die Kabelschuhe 1 bis 3 vorzugsweise für die zu den drei Phasen führenden Leitungen und der Kabelschuh 4 für die zur Erde führende Leitung vorgesehen sind. Die Löcher in den Kabelschuhösen5 sind mit gezahnten Rändern 6 versehen. Die Kabelschuhe werden durch die Schraube 7 zusammengehalten, auf die eine Mutter 8 aufgeschraubt wird, wobei Unterlagsscheiben 9 verwendet sind. Die Schraube 7 ist von einer Hülse 10 umgeben, deren Außenumfang mit achtzehn Zähnen 11 versehen ist, die gleitend in die Zähne der Ränder der Löcher der Kabelschuhösen passen. Der z. B. zwischen den Kabelschuhen 1 und 2 bestehende Winkel von 60° kann gewünschtenfalls geändert werden, indem der Sternpunkt auseinandergenommen wird und die Hülse nach gegenseitigem Verdrehen der Kabelschuhe wieder eingesetzt wird.An exemplary embodiment of the invention is shown in the drawing shown, namely F i g. 1 a plan view of the star point, with the screw head and the washer are omitted, FIG. 2 a section through the star point according to the line II-II of FIG. 1 and F i g. 3 is an enlarged end view of FIG Sleeve. The star point has the four cable lugs 1 to 4, of which the cable lugs 1 to 3 preferably for the lines leading to the three phases and the cable lug 4 are provided for the line leading to earth. The holes in the cable lug eyes 5 are provided with toothed edges 6. The cable lugs are through the screw 7 held together, onto which a nut 8 is screwed, with washers 9 are used. The screw 7 is surrounded by a sleeve 10, the outer circumference of which is provided with eighteen teeth 11 which slide into the teeth of the edges of the holes the cable lug eyes fit. The z. B. between the cable lugs 1 and 2 existing Angle of 60 ° can be changed if desired by taking the star point apart and the sleeve is reinserted after the cable lugs have been twisted against each other will.
