- the surge arrester acts like an isolator.
- the surge arrester When an overvoltage occurs due to, for example, lightning strikes or switching operations, the surge arrester becomes conductive and conducts the overvoltage to earth. If the overvoltage has subsided, the surge arrester is again insulating.
- the surge arrester has a discharge column with a voltage-dependent electrical resistance, a so-called varistor. Below a threshold voltage, which is a material property of the varistor, the rejection column is high-impedance and acts as an insulator. When the threshold voltage is exceeded, the resistance of the varistor decreases, the rejection column becomes conductive and conducts the overvoltage to earth.

- a pressure screw is screwed, which exerts an axial pressure on the Ableit yarn.
- an externally accessible connecting bolt which serves for the electrical connection, is screwed into this bore. Both require to transmit the necessary forces a screwed in the thread minimum length. This essentially determines the thickness of the end fitting. Efforts to make the end fitting more compact to reduce the overall length of the surge arrester are hampered by the minimum required length.
- the object of the invention is to provide a surge arrester with compact end fittings.
- a surge arrester has a discharge column extending along a longitudinal axis, which is formed from a plurality of stacked varistor blocks.

- the second thread extends into the axial recess. It can be arranged on the outer or inner wall of the recess.
- the bottom has a tool holder for receiving a screwing tool.
- the tool holder may for example be a hexagonal hole for receiving an Allen key.
- a tool can be inserted through the bore of the first thread to rotate from the outside of the pressure screw and thus to tension the Ableit yarn.
- the pressure screw has one or more injection openings, which serve to inject potting compound into the hollow interior.
- each injection opening extends from the bottom to the side wall of the pressure screw.
- the second thread is an internal thread and the pressure screw has a corresponding external thread on its side wall.
- the pressure screw has a cylindrical outer circumferential surface with a thread corresponding to the second thread.
- the fitting body is designed like a ring with a cylindrical inner circumferential surface, wherein the second thread is arranged on the inner circumferential surface.
- the pressure screw has a cylindrical outer circumferential surface with a second thread corresponding thread on.

- a pressure screw is arranged in each second thread.
- the tension of the delivery column takes place outside of the longitudinal axis in several places, which can be a better pressure distribution on the Ableit yarn reach.
- the FIG. 1 shows a conventional surge arrester 1 in the so-called cage design with a consisting of several varistor elements Ableit yarn 2.
- the Ableit yarn 2 may contain other elements such as metal blocks (not shown) for length compensation.
- the Ableit yarn 2 is held at both ends by end fittings 30.

- the first portion 12 has a first thread 7, the second portion 13 a second thread 8.
- As a thread screw threads are understood in the context of the invention, which are arranged as an internal thread on an inner circumferential surface of a circular cylindrical bore or as an external thread on a circular cylindrical outer surface.

- a force is exerted on the delivery column 2, which is absorbed by the tension elements 4.
- a thrust washer 11 can be arranged between the pressure screw 14 and the outermost varistor block 5 of the diverter column 2. After tensioning the delivery column 2, the connecting bolt 15 can be screwed into the first thread 7 of the central bore 6.
- Both the first thread 7, and the second thread 8 need a certain minimum length L1 and L2, since the connecting bolt 15 and pressure screw 14 each require a certain screwing depth in order to remove the forces occurring on the flange can.
- the second thread 8 must also have enough leeway so that the pressure screw 14 can be rotated sufficiently far out of the second thread 8, in order to transmit the necessary compressive force to the Ableitkla 2.
- the necessary minimum length L1, L2 the thread 7, 8 determines the minimum height of the end fitting 30 and limited efforts to make this more compact.

It is compared to the end fitting 30 of FIG. 2 the central bore 6 of the valve body 10 in the region of the second portion 13 in diameter greatly increased. Instead of a massive pressure screw 14, this is pot-shaped, with a hollow circular cylindrical side wall 20 and a circular bottom 21, which closes the side wall 20 frontally.

Description
Die Erfindung betrifft Überspannungsableiter, wie sie zum Schutz vor Überspannungen in elektrischen Energieübertragungsnetzen eingesetzt werden. Ein solcher Überspannungsableiter ist einerseits elektrisch mit einer Hoch- oder Mittelspannungsübertragungsleitung verbunden, andererseits mit Erdpotential. Im Normalbetrieb wirkt der Überspannungsableiter wie ein Isolator. Bei Auftreten einer Überspannung durch zum Beispiel Blitzeinschlag oder Schaltvorgänge wird er Überspannungsableiter leitend und leitet die Überspannung zur Erde hin ab. Ist die Überspannung abgeklungen, so wird der Überspannungsableiter wieder isolierend. Dazu weist der Überspannungsableiter eine Ableitsäule mit einem spannungsabhängigen elektrischen Widerstand, einem sogenannten Varistor, auf. Unterhalb einer Schwellenspannung, die eine Materialeigenschaft des Varistors ist, ist die Ableitsäule hochohmig und wirkt als Isolator. Bei Überschreiten Schwellenspannung verringert sich der Widerstand des Varistors, die Ableitsäule wird leitend und leitet die Überspannung zur Erde hin ab.The invention relates to surge arresters, as they are used to protect against surges in electrical energy transmission networks. Such a surge arrester is on the one hand connected electrically to a high or medium voltage transmission line, on the other hand to ground potential. In normal operation, the surge arrester acts like an isolator. When an overvoltage occurs due to, for example, lightning strikes or switching operations, the surge arrester becomes conductive and conducts the overvoltage to earth. If the overvoltage has subsided, the surge arrester is again insulating. For this purpose, the surge arrester has a discharge column with a voltage-dependent electrical resistance, a so-called varistor. Below a threshold voltage, which is a material property of the varistor, the rejection column is high-impedance and acts as an insulator. When the threshold voltage is exceeded, the resistance of the varistor decreases, the rejection column becomes conductive and conducts the overvoltage to earth.
Für Anwendungen in elektrischen Übertragungsnetzen ist eine Ableitsäule eines Überspannungsableiters häufig als zylindrische Säule aus aufeinander gestapelten einzelnen Varistorblöcken aufgebaut. Die Varistorblöcke sind ihrerseits zylindrische, meist kreiszylindrische, Blöcke aus einem spannungsabhängigen Material wie beispielsweise Zinkoxid oder Siliziumkarbid. Diese sind mit ihren Stirnflächen aufeinander zur Ableitsäule gestapelt. Damit die Ableitsäule einerseits mechanisch stabil ist und andererseits die Varistorblöcke einen guten elektrischen Kontakt miteinander haben, muss die Ableitsäule unter Druck zusammengehalten werden. Grundsätzlich unterscheidet man zwei unterschiedliche Bauweisen.For applications in electrical transmission networks, a rejection column of a surge arrester is often constructed as a cylindrical column of stacked individual varistor blocks. The varistor blocks are in turn cylindrical, usually circular cylindrical, blocks of a voltage-dependent material such as zinc oxide or silicon carbide. These are stacked with their faces to each other to Ableitsäule. In order to ensure that the diverter column is mechanically stable on the one hand and that the varistor blocks have good electrical contact with one another on the other hand, the diverter column must be held together under pressure. Basically, there are two different types of construction.
Beim sogenannten Rohr-Design ist die Ableitsäule in einem mechanisch stabilen Gehäuse angeordnet und zwischen Flanschen des Gehäuses eingespannt.In the so-called tube design, the rejection column is arranged in a mechanically stable housing and clamped between flanges of the housing.
Beim sogenannten Käfig-Design ist die Ableitsäule von einem Käfig aus Zugelementen, beispielsweise aus glasfaserverstärktem Kunststoff, umgeben, die in Endarmaturen verspannt sind und so die Ableitsäule zusammenhalten.In the so-called cage design, the rejection column is surrounded by a cage made of tension elements, for example of glass fiber reinforced plastic, which are braced in end fittings and thus hold together the Ableitsäule.
Es gibt auch Mischformen, bei dem eine durch Zugelemente eingespannte Ableitsäule in einem mechanisch stabilen Gehäuse angeordnet ist. Dies erhöht die mechanische Stabilität und erleichtert die Montage.There are also mixed forms, in which a tensioning element clamped by tension elements is arranged in a mechanically stable housing. This increases the mechanical stability and facilitates the assembly.
Für Freiluftanwendungen weist der Überspannungsableiter einen Außenmantel aus einem wetterfesten Material, wie beispielsweise Silikon, auf.For outdoor applications, the surge arrester has an outer jacket made of a weatherproof material, such as silicone.
Die Erfindung betrifft einen Überspannungsableiter im Käfig-Design unabhängig davon, ob dieser zusätzlich in einem mechanisch stabilen Gehäuse angeordnet ist.The invention relates to a surge arrester in the cage design, regardless of whether this is additionally arranged in a mechanically stable housing.
Die
Aufgabe der Erfindung ist es, einen Überspannungsableiter mit kompakten Endarmaturen anzugeben.The object of the invention is to provide a surge arrester with compact end fittings.
Dabei weist ein Überspannungsableiter eine sich entlang einer Längsachse erstreckende Ableitsäule auf, die aus mehreren aufeinandergestapelten Varistorblöcken gebildet ist. Die Ableitsäule ist mittels mehrerer diese radial umgebenden und in Endarmaturen festgelegten Zugelemente zwischen den Endarmaturen eingespannt. Zumindest eine der Endarmaturen weist ein erstes Gewinde zur Befestigung eines Anschlussbolzens auf. Der Anschlussbolzen dient zum Anschluss des Überspannungsableiters an eine Freileitung eines Energieübertragungsnetzes. Außerdem weist die Endarmatur einen Armaturkörper mit einem zweiten Gewinde zur Aufnahme einer Druckschraube zur Erzeugung einer axialen Kraft auf die Ableitsäule auf. Mittels der Druckschraube wird die Ableitsäule axial zusammengepresst um einen möglichst guten Kontakt zwischen den die Ableitsäule bildenden Varistorblöcken zu ermöglichen. Erfindungsgemäß ist vorgesehen, dass das erste Gewinde und das zweite Gewinde derart zueinander angeordnet sind, dass sie sich entlang eines axialen, also eines sich parallel zur Längsachse erstreckenden, Abschnitts überlappen. Das erste und zweite Gewinde sind also derart parallel zueinander und parallel zur Längsachse angeordnet, dass eine radiale, also senkrecht zur Längsachse ausgerichtete Ebene, die innerhalb von diesem axialen Abschnitt liegt, sowohl das erste Gewinde, als auch das zweite Gewinde schneidet. Dadurch kann der Armaturkörper und damit die Endarmatur in der Höhe um die Länge des axialen Abschnitts verkürzt gebaut werden.In this case, a surge arrester has a discharge column extending along a longitudinal axis, which is formed from a plurality of stacked varistor blocks. The Ableitsäule is clamped by a plurality of these radially surrounding and fixed in Endarmaturen tension elements between the end fittings. At least one of the end fittings has a first thread for attachment of a connecting bolt. The connecting bolt is used to connect the surge arrester to an overhead line of an energy transmission network. In addition, the end fitting has a fitting body with a second thread for receiving a pressure screw for generating an axial force on the Ableitsäule. By means of the pressure screw, the delivery column is compressed axially in order to allow the best possible contact between the Varistorblöcken forming the Ableitsäule. According to the invention, it is provided that the first thread and the second thread are arranged relative to one another such that they overlap along an axial section, that is to say a section extending parallel to the longitudinal axis. The first and second threads are thus arranged parallel to one another and parallel to the longitudinal axis such that a radial plane oriented perpendicularly to the longitudinal axis, which lies within this axial section, intersects both the first thread and the second thread. As a result, the fitting body and thus the end fitting can be shortened in height by the length of the axial section.
Vorzugsweise sind das erste und zweite Gewinde koaxial zueinander und zur Längsachse angeordnet. Dies erleichtert die Herstellung und Montage.Preferably, the first and second threads are coaxial with each other and arranged with respect to the longitudinal axis. This facilitates the manufacture and assembly.
In einer bevorzugten ersten Ausführungsform ist auch das erste Gewinde ein im Armaturkörper angeordnetes Innengewinde. Erstes und zweites Gewinde sind koaxial zueinander und zur Längsachse angeordnet. Die Druckschraube ist topfartig ausgeführt und in das zweite Gewinde eingeschraubt. Die Druckschraube weist einen zur Ableitsäule weisenden Boden und eine sich von diesem und der Ableitsäule weg erstreckende Seitenwand auf. Boden und Seitenwand umschließen einen hohlen Innenraum. Der Armaturkörper weist eine ringartige axiale Vertiefung auf, die sich in axialer Richtung vom inneren, also zur Ableitsäule weisenden Ende des ersten Gewindes nach außen, also von der Ableitsäule weg erstreckt. Das zweite Gewinde erstreckt sich in die axiale Vertiefung hinein. Es kann dabei auf der Außen- oder Innenwand der Vertiefung angeordnet sein.In a preferred first embodiment, the first thread is an internal thread arranged in the fitting body. First and second threads are coaxial with each other and arranged to the longitudinal axis. The pressure screw is pot-shaped and screwed into the second thread. The pressure screw has a bottom facing the Ableitsäule and a extending from this and the Ableitsäule away sidewall. Floor and side wall enclose a hollow interior. The fitting body has an annular axial recess which extends in the axial direction from the inner, ie pointing to the Ableitsäule end of the first thread to the outside, ie away from the Ableitsäule. The second thread extends into the axial recess. It can be arranged on the outer or inner wall of the recess.
Vorzugsweise weist der Boden eine Werkzeugaufnahme zur Aufnahme eines Schraubwerkzeugs auf. Die Werkzeugaufnahme kann beispielsweise ein Sechskantloch zur Aufnahme eines Inbus-Schlüssels sein. Dadurch kann ein Werkzeug durch die Bohrung des ersten Gewindes eingeführt werden, um von außen die Druckschraube zu drehen und damit die Ableitsäule zu spannen.Preferably, the bottom has a tool holder for receiving a screwing tool. The tool holder may for example be a hexagonal hole for receiving an Allen key. As a result, a tool can be inserted through the bore of the first thread to rotate from the outside of the pressure screw and thus to tension the Ableitsäule.
In einer bevorzugten Ausgestaltung der ersten Ausführungsform weist die Druckschraube ein oder mehrere Einspritzöffnungen auf, die dem Einspritzen von Vergussmasse in den hohlen Innenraum dienen. Bevorzugt erstreckt sich jede Einspritzöffnung vom Boden bis in die Seitenwand der Druckschraube. So kann beim Herstellen der Außenumhüllung, die üblicherweise durch Spritzgießen hergestellt wird, gleichzeitig der Innenraum mit Vergussmasse gefüllt und so abgedichtet werden. Aufwändige Dichtmaßnahmen können damit entfallen.In a preferred embodiment of the first embodiment, the pressure screw has one or more injection openings, which serve to inject potting compound into the hollow interior. Preferably, each injection opening extends from the bottom to the side wall of the pressure screw. Thus, in the manufacture of the outer envelope, which is usually produced by injection molding, at the same time the interior is filled with potting compound and sealed so. Elaborate sealing measures can be dispensed with.
Bevorzugt wird auch, dass das zweite Gewinde ein Innengewinde ist und die Druckschraube an ihrer Seitenwand ein entsprechendes Außengewinde aufweist. Die Druckschraube weist dabei eine zylindrische Außenmantelfläche mit einem zum zweiten Gewinde korrespondierenden Gewinde auf.It is also preferred that the second thread is an internal thread and the pressure screw has a corresponding external thread on its side wall. The pressure screw has a cylindrical outer circumferential surface with a thread corresponding to the second thread.
In einer zweiten Ausführungsform der Erfindung ist der Armaturkörper ringartig mit einer zylindrischen Innenmantelfläche ausgeführt, wobei das zweite Gewinde auf der Innenmantelfläche angeordnet ist. Die Druckschraube weist dabei eine zylindrische Außenmantelfläche mit einem zum zweiten Gewinde korrespondierenden Gewinde auf. Zum Spannen der Ableitsäule wird der Armaturkörper festgehalten, während die Druckschraube mittels eines Werkzeugs gedreht wird. Alternativ kann die Druckschraube festgehalten werden und die beiden gegenüberliegenden Armaturkörper mitsamt der Ableitsäule und den Zugelementen gemeinsam gedreht werden. Vorzugsweise sind dabei bei einer der Endarmaturen das erste und zweite Gewinde als Linksgewinde und bei der gegenüberliegenden Endarmatur als Rechtsgewinde ausgeführt. So können in einem Arbeitsgang beide Endarmaturen gleichmäßig gespannt werden.In a second embodiment of the invention, the fitting body is designed like a ring with a cylindrical inner circumferential surface, wherein the second thread is arranged on the inner circumferential surface. The pressure screw has a cylindrical outer circumferential surface with a second thread corresponding thread on. To clamp the Ablesitsäule the valve body is held while the pressure screw is rotated by a tool. Alternatively, the pressure screw can be held and the two opposite fitting body together with the Ableitsäule and the tension elements are rotated together. Preferably, in one of the end fittings, the first and second threads are designed as left-hand threads and at the opposite end fittings as right-hand threads. This allows both end fittings to be tensioned evenly in one operation.
Vorteilhaft ist bei der zweiten Ausführungsform, wenn die Druckschraube den Armaturkörper vollständig durchdringt, wobei das erste Gewinde in der Druckschraube angeordnet ist. So lässt sich die Druckschraube besonders einfach gestalten und herstellen.It is advantageous in the second embodiment, when the pressure screw completely penetrates the fitting body, wherein the first thread is arranged in the pressure screw. This makes the pressure screw particularly easy to design and manufacture.
In einer dritten Ausführungsform der Erfindung ist das erste Gewinde im Armaturkörper angeordnet, wobei in einem radialen Abstand um das erste Gewinde mehrere zweite Gewinde um das erste Gewinde herum verteilt angeordnet sind, Dabei ist in jedem zweiten Gewinde eine Druckschraube angeordnet. Die Spannung der Ableitsäule erfolgt so außerhalb der Längsachse an mehreren Stellen, womit sich eine bessere Druckverteilung auf die Ableitsäule erreichen lässt.In a third embodiment of the invention, the first thread in the fitting body is arranged, wherein at a radial distance around the first thread a plurality of second threads are arranged distributed around the first thread around, Here, in each second thread, a pressure screw is arranged. The tension of the delivery column takes place outside of the longitudinal axis in several places, which can be a better pressure distribution on the Ableitsäule reach.

Sowohl das erste Gewinde 7, als auch das zweite Gewinde 8 benötigen eine gewisse Mindestlänge L1 bzw. L2, da Anschlussbolzen 15 und Druckschraube 14 jeweils eine bestimmte Einschraubtiefe benötigen, um die auftretenden Kräfte auf den Flansch abtragen zu können. Insbesondere das zweite Gewinde 8 muss außerdem genügend Spielraum aufweisen, damit die Druckschraube 14 genügend weit aus dem zweiten Gewinde 8 heraus gedreht werden kann, um die notwendige Druckkraft auf die Ableitsäule 2 zu übertragen. Die notwendige Mindestlänge L1, L2 der Gewinde 7, 8 bestimmt die Mindestbauhöhe der Endarmatur 30 und beschränkt Bemühungen, diese kompakter zu gestalten.Both the

Im Bereich des Bodens 21 weist die Druckschraube 14 eine Werkzeugaufnahme 16 hier in Form eines Innensechskant auf. In diese kann durch die zentrale Bohrung 6 von außen ein Werkzeug eingesetzt werden, um die Druckschraube 14 zu drehen und gegen die Ableitsäule 2 zu pressen, um die notwendige Druckkraft zu erzeugen. Statt eines Innensechskantes könnte der Boden 21 auch auf seiner der Ableitsäule 2 entgegengesetzten Seite eine Aufnahme für einen Steckschlüssel aufweisen.In the region of the bottom 21, the
Der Boden 21 kann außerdem eine oder mehrere Einspritzöffnungen 17 aufweisen, die sich bis in die Seitenwand 20 hinein erstrecken. Durch diese Einspritzöffnungen 17 kann beim Guss der äußeren Umhüllung 31 Vergussmasse, beispielsweise Silikon, in den Innenraum 22 der Druckschraube 14 eintreten und so die zentrale Bohrung 6 abdichten. Ein bisher übliches Abdichten von der Außenseite der Endarmatur 3 kann damit entfallen.The
In einer zweiten Ausführungsform der Erfindung ist der Armaturkörper 10 ringartig ausgeführt. Er weist eine zylindrische Innenmantelfläche auf, auf der das zweite Gewinde 8 angeordnet ist. Die Druckschraube 14 weist eine zylindrische Außenmantelfläche mit einem dazu korrespondierenden Gewinde auf. In der hier dargestellten bevorzugten Ausführung durchdringt die Druckschraube 14 den Armaturkörper 10 vollständig. Das erste Gewinde 7 ist in der Druckschraube 14 angeordnet, vorzugsweise wie hier dargestellt, koaxial mit dem zweiten Gewinde 8. Das erste Gewinde erstreckt sich über einen ersten Abschnitt 12, das zweite über einen zweiten Abschnitt 13.
