Abstract
Description
Die Erfindung bezieht sich auf eine Anordnung zum Befesti
gen von N-Leitern an geerdeten Niederspannungs-Stahlbeton
masten, vorzugsweise mit Bewehrungs-Erdungsanlage
Es ist bekannt, bei Freileitungen mit einem Drehstrom-Nie
derspannungssystem die vier Leiter (R, S, T, N) am Mast
isoliert zu befestigen.The invention relates to an arrangement for fastening gene N conductors to grounded low-voltage reinforced concrete masts, preferably with rebar earthing system
It is known to attach the four conductors (R, S, T, N) insulated to the mast in overhead lines with a three-phase power supply system.
Dabei wird bei der üblicherweise eingesetzten Schutzmaßnah me Nullung bei allen geerdeten Masten die Isolation beim N-Leiter durch die Überbrückung des Isolators mit einer Erd verbindungsleitung zur Anschlußstelle der Masterdungsanlage aufgehoben.The usual protective measure is used me zeroing for all grounded masts the insulation at N conductor by bridging the insulator with an earth Connection line to the connection point of the master earthing system canceled.
Diese Anschlußstelle kann mit einem gesonderten Erdungs stahl bzw. als Erdungs-Gewindehülse ausgebildet, mit der Bewehrung des Stahlbetonmastes elektrisch verbunden sein.This connection point can be earthed separately steel or as a grounding threaded sleeve with which Reinforcement of the reinforced concrete mast must be electrically connected.
Eine solche Erdungs-Gewindehülse ist mit der DD-PS 1 51 245 bekanntgeworden, mit der ein elektrisch leitfähiger An schluß über eine zwei Bewehrungsstähle des Stahlbetonmastes umfassende Stahlklammer zur Nutzung der Mastfundamenterder wirkung über die Bewehrung herstellbar ist.Such a grounding threaded sleeve is with DD-PS 1 51 245 with which an electrically conductive type conclusion about a two reinforcing steel of the reinforced concrete mast Comprehensive steel clamp for using the mast foundation earth electrode effect can be produced via the reinforcement.
Nachteilig bleibt es dabei, daß der an einem Isolator be festigte N-Leiter einer Überbrückung bedarf, bestehend aus Seil, Seilklemme und Erdungsanschlußklemme, damit der N-Lei ter mit der Erdungsanlage des Stahlbetonmastes elektrisch leitend verbunden ist. The disadvantage remains that the be on an insulator strengthened neutral conductor needs a bridging, consisting of Rope, rope clamp and earth connection clamp, so that the N-Lei ter with the grounding system of the reinforced concrete mast electrical is conductively connected.
Hier will die Erfindung Abhilfe schaffen. Die Erfindung, wie sie in den Ansprüchen gekennzeichnet ist, löst die Auf gabe, einen N-Leiter an einem Niederspannungs-Stahlbeton mast derart zu befestigen, daß der Leiter neben der mecha nischen Befestigung gleichermaßen elektrisch leitfähig mit der Erdungsanlage des Stahlbetonmastes verbunden ist.The invention seeks to remedy this. The invention, as characterized in the claims, resolves the Auf nabe on a low-voltage reinforced concrete to attach the mast in such a way that the conductor next to the mecha African fastening equally electrically conductive the earthing system of the reinforced concrete mast is connected.
Die durch die Erfindung erreichten Vorteile sind im wesent lichen darin zu sehen, daß die Überbrückung des sonst den N-Leiter befestigenden Isolators mit einer Erdungsverbin dungsleitung zur Anschlußstelle der Masterdungsanlage ent fallen kann.The advantages achieved by the invention are essential lichen to see that the bridging of the otherwise N-conductor fastening insulator with a ground connection cable to the connection point of the master system can fall.
Im folgenden wird die Erfindung anhand von einen Ausfüh rungsweg darstellenden Zeichnungen näher erläutert.In the following the invention is based on an embodiment approximately illustrated drawings.
In der Zeichnung zeigtIn the drawing shows
Fig. 1 die Befestigung des N-Leiters für einen Spannbeton mast in Tragefunktion ohne Leitungsabzweig; Figure 1 shows the attachment of the N-conductor for a prestressed concrete mast in a carrying function without a line branch.
Fig. 2 die Anschlußstelle gemäß Fig. 1 im Schnitt; Fig. 2 shows the junction of Figure 1 in section.
Fig. 3 die Befestigung an einem Spannbetonmast höherer me chanischer Belastung, beispielsweise bei Leitungs abzweig; Figure 3 shows the attachment to a prestressed concrete mast higher me mechanical load, for example in line branch.
Fig. 4 die Anschlußstelle gemäß Fig. 3 im Schnitt. Fig. 4, the junction of FIG. 3 in section.
Fig. 2 und Fig. 4 zeigen eine an sich bekannte Erdungsanla ge an Stahlbetonmasten, bestehend aus Bewehrungsstählen 3 oder auch einen gesondert eingelegten Erdungs-Rundstahl und eine zwei Bewehrungsstähle 3 umfassende Stahlklemme 2, die mit einer Erdungsanschluß-Gewindehülse 4 in Höhe der übli chen Lage des N-Leiters am Mast angeordnet ist. Fig. 2 and Fig. 4 show a known ge earthing system on reinforced concrete poles, consisting of reinforcing steel 3 or a separately inserted round earthing steel and a two reinforcing steel 3 comprehensive steel clamp 2 , the Chen with an earth connection threaded sleeve 4 in the amount of übli Position of the N conductor is arranged on the mast.
Fig. 1 zeigt einen Gewindebolzen 1 mit stirnseitig starr angeordneter Seilklemme. Dieser Gewindebolzen 1 wird zur Herstellung des mechanischen Befestigungspunktes und der elektrisch leitenden Verbindung zum Erdpotential in die Erdungsanschluß-Gewindehülse 4 eingeschraubt. Fig. 1 shows a threaded bolt 1 with a rigidly arranged rope clamp on the end face. This threaded bolt 1 is screwed into the ground connection threaded sleeve 4 to produce the mechanical fastening point and the electrically conductive connection to earth potential.
Eine weitere Ausführungsmöglichkeit zeigt Fig. 3, bei der der Gewindebolzen 1 ebenfalls in die Erdungsanschluß-Gewin dehülse 4 einschraubbar ist, jedoch verlängert ausgebildet, durch ein gegenüber der Erdungs-Gewindehülse 4 liegende Öffnung im Stahlbetonmast steckbar und gegen diesen ver schraubbar ist. Damit sind auch höhere mechanische Bela stungen, wie beispielsweise bei Leitungsabzweigen, be herrschbar.A further embodiment is shown in FIG. 3, in which the threaded bolt 1 is also screwed into the ground connection thread sleeve 4 , but has an elongated design, can be inserted through an opening opposite the grounding threaded sleeve 4 in the reinforced concrete mast and screwed against it. This means that higher mechanical loads, such as with line feeders, can be controlled.
Die Auslegung der im Ausführungsbeispiel beschriebenen Anordnung mit ihren Kontaktstellen zum Leiterseil und zur Mast-Erdungsanlage ist zwar nicht Gegenstand der Erfindung, muß jedoch derart bemessen sein, daß diese den mechani schen, elektrischen und thermischen Beanspruchungen stand hält. Dies betrifft insbesondereThe interpretation of those described in the exemplary embodiment Arrangement with their contact points to the conductor rope and Mast earthing system is not the subject of the invention, However, it must be such that this mechani mechanical, electrical and thermal loads holds. This applies in particular
- - die Aufnahme der äußeren Lasten des N-Leiters, der meist ein Aluminium- oder Aluminium-Stahlseil ist,- The absorption of the external loads of the N conductor, the is usually an aluminum or aluminum steel cable,
- - die schwingungssichere Leiterseilbefestigung,- the vibration-proof ladder cable attachment,
- - die widerstandsarme Ableitung der Fehlerströme von dem Leiter über den Gewindebolzen 1 mit Seilklemme zur Erdungsanlage.- The low-resistance derivation of the fault currents from the conductor via the threaded bolt 1 with a cable clamp to the earthing system.
