Description

Die Erfindung betrifft eine Hochspannungssicherung, insbesondere zur Verwendung bei hohen Temperaturen unter Öl, nach dem Oberbegriff des Anspruchs 1.The invention relates to a high-voltage fuse, in particular for use at high temperatures under oil, according to the preamble of claim 1.

Eine gattungsgemäße Hochspannungssicherungssicherung ist bereits aus der US - A - 5 892 427 bekannt. Diese Hochspannungssicherung weist endseitig jeweils eine Hilfskappe und eine Oberkappe auf. Des weiteren weist die bekannte Sicherung einen Isolierkörper mit einer endseitigen umlaufenden Ringnut auf. Zur Verbindung der Kappen mit dem Isolierkörper sind die Hilfskappe und die Oberkappe jeweils in die Ringnut eingebördelt. Nachteilig ist, daß die bekannte Hochspannungssicherung keine hinreichende Dichtigkeit bietet. Eine derartige Dichtigkeit ist jedoch insbesondere dann erforderlich, wenn derartige Sicherungen unter Öl montiert werden, so daß eine Öldichtigkeit gegeben ist. Die bekannte Hochspannungssicherung ist zur Verwendung bei hohen Temperaturen unter Öl nicht geeignet.A generic high-voltage fuse is already out of the US Pat. No. 5,892,427 known. This high-voltage fuse has at each end an auxiliary cap and an upper cap. Furthermore, the known fuse has an insulating body with an end-side circumferential annular groove. To connect the caps with the insulating body, the auxiliary cap and the top cap are each crimped in the annular groove. The disadvantage is that the known high-voltage fuse does not provide sufficient tightness. However, such tightness is particularly necessary when such fuses are mounted under oil, so that an oil seal is given. The known high voltage fuse is not suitable for use at high temperatures under oil.

Öldichte Hochspannungssicherungen werden in der Regel unter Öl montiert, wobei die maximale Temperatur zum Teil 60 °C überschreitet und Temperaturen bis 150 °C, erreicht werden, in der Regel zumindest 100 °C. Sicherheitsprüfungen, beispielsweise nach IEC 60 282-1, werden allerdings bei maximal 85 °C durchgeführt. Gleichwohl ist es von wesentlicher Bedeutung, daß die vorgenannten Sicherungen bei hohen Temperaturen bis 150 °C öldicht sind. Die Verwendung von Hochspannungssicherungen unter hohen Temperaturen führt zu folgenden Problemen. Dabei ist es so, daß mit steigender Einsatztemperatur die Materialdehnung der Kappen zunimmt. Besonders betroffen ist davon der Preßsitz zwischen der Oberkappe und der Hilfskappe bzw. zwischen der Hilfskappe und dem keramischen Isolierkörper. Die durch einen Preßsitz erwirkte kraftschlüssige Verbindung zwischen der Oberkappe und der Hilfskappe bzw. zwischen der Hilfskappe und dem keramischen Isolierkörper verliert mit zunehmender Materialdehnung an Festigkeit, was bei höheren Temperaturen zum Teil dazu führt, daß sich die Kappen derart ausdehnen, daß sich ein Spalt bildet und Öl in die Sicherung eindringt. Zum anderen steigt bedingt durch die höheren Temperaturen der Druck im geschlossenen Isolierkörper. Hier kann es zu einem Abheben der Kappen kommen.Oil-tight high-voltage fuses are usually mounted under oil, the maximum temperature sometimes exceeding 60 ° C and reaching temperatures of up to 150 ° C, usually at least 100 ° C. However, safety tests, for example according to IEC 60 282-1, are carried out at a maximum of 85 ° C. However, it is essential that the aforementioned fuses are oil-tight at high temperatures up to 150 ° C. The use of high-voltage fuses under high temperatures leads to the following problems. It is so that the material expansion of the caps increases with increasing operating temperature. Particularly affected is the press fit between the top cap and the auxiliary cap or between the auxiliary cap and the ceramic insulator. The obtained by a press fit frictional connection between the top cap and the auxiliary cap or between the auxiliary cap and the ceramic insulating loses strength with increasing material expansion, which at higher temperatures in part leads to the fact that the caps expand so that a gap is formed and oil enters the fuse. On the other hand, conditionally due to the higher temperatures, the pressure in the closed insulating body. This can lead to a lifting of the caps.

Aufgabe der vorliegenden Erfindung ist es, eine Hochspannungssicherung der eingangs genannten Art zur Verfügung zu stellen, die einfach und kostengünstig herstellbar ist und auch bei hohen Temperaturen eine hinreichende Öldichtigkeit gewährleistet.Object of the present invention is to provide a high-voltage fuse of the type mentioned, which is simple and inexpensive to produce and ensures sufficient oil resistance even at high temperatures.

Die vorgenannte Aufgabe ist bei einer Hochspannungssicherung der eingangs beschriebenen Art durch die Merkmale des Anspruchs 1 gelöst. Durch die formschlüssige Verbindung zwischen der Hilfskappe und dem Isolierkörper wird gewährleistet, daß es auch bei hohen Temperaturen nicht zu einem Abheben der Hilfskappe und damit der auf der Hilfskappe aufgesetzten Oberkappe von dem Isolierkörper und einem Eindringen von Öl in das Innere des Isolierkörpers kommen kann. Die formschlüssige Verbindung sorgt auch bei Temperaturen von mehr als 100 °C, bis vorzugsweise 150 °C, für eine ausreichende Festigkeit der Kappen auf dem Keramikrohr, wobei grundsätzlich auch höhere Temperaturen möglich sind. Im übrigen ist die erfindungsgemäße Hochspannungssicherung sehr einfach und kostengünstig herstellbar, wobei eine hinreichende Öldichtigkeit auch bei hohen Temperaturen gewährleistet ist. Die kostengünstige Fertigung ergibt sich dadurch, daß im Isolierkörper endseitig jeweils nur eine einzige Vertiefung erforderlich ist, die nicht nur zur Herstellung des Formschlusses zwischen der Oberkappe und der Hilfskappe dient, sondern auch das Dichtmittel aufnimmt. Darüber hinaus wirkt die Hilfskappe und/oder die Oberkappe auf das Dichtmittel, um eine hohe Dichtwirkung zu erzeugen. Es ergibt sich also ein kombinatorischer Effekt der Formschlußbildung zwischen Oberkappe bzw. Hilfskappe und dem Isolierkörper einerseits und der Druckbeaufschlagung des Dichtmittels durch die Oberkappe bzw. die Hilfskappe andererseits, und zwar in der gleichen Vertiefung des Isolierkörpers. Letztlich läßt sich bei sehr einfachen und kostengünstigen Ausführungsformen das Einrollen der jeweiligen Kappen in die Vertiefung gleichzeitig mit der Druckbeaufschlagung der Dichtung verbinden.The above object is achieved in a high-voltage fuse of the type described above by the features of claim 1. Due to the positive connection between the auxiliary cap and the insulating ensures that it can not come to a lifting of the auxiliary cap and thus the upper cap on the cap from the insulator and an intrusion of oil into the interior of the insulator even at high temperatures. The positive connection ensures even at temperatures of more than 100 ° C, preferably up to 150 ° C, for a sufficient strength of the caps on the ceramic tube, which in principle also higher temperatures are possible. Moreover, the high-voltage fuse according to the invention is very simple and inexpensive to produce, with a sufficient oil tightness is ensured even at high temperatures. The cost-effective production results from the fact that only one recess is required in the insulating end, which not only serves to produce the positive connection between the top cap and the auxiliary cap, but also absorbs the sealant. In addition, the auxiliary cap and / or the top cap acts on the sealant to produce a high sealing effect. Thus, there is a combinatorial effect of positive engagement between the upper cap or auxiliary cap and the insulating body on the one hand and the pressurization of the sealant through the top cap and the auxiliary cap on the other hand, in the same recess of the insulator. Finally, in very simple and inexpensive embodiments, the curling of the respective caps in the recess can be combined simultaneously with the pressurization of the seal.

Um eine noch höhere Festigkeit der Kappen auf dem Isolierkörper zu gewährleisten, kann vorgesehen sein, daß die Oberkappe derart gegen die Hilfskappe und/oder den Isolierkörper verformt ist, daß sich eine formschlüssige Verbindung zwischen der Oberkappe und der Hilfskappe und/oder zwischen der Oberkappe und dem Isolierkörper ergibt. Der Erfindung liegt somit der Grundgedanke zugrunde, daß die Oberkappe und die Hilfskappe formschlüssig miteinander und/oder mit dem Isolierkörper verbunden sind, um auch bei erhöhten Temperaturen eine ausreichende Öldichtigkeit der erfindungsgemäßen Hochspannungssicherung zu ermöglichen.In order to ensure an even higher strength of the caps on the insulator, it can be provided that the upper cap is deformed against the auxiliary cap and / or the insulating body so that a positive connection between the top cap and the auxiliary cap and / or between the top cap and the insulating results. The invention is thus based on the basic idea that the top cap and the auxiliary cap are positively connected with each other and / or with the insulating body to allow sufficient oil resistance of the high-voltage fuse according to the invention even at elevated temperatures.

Bei einer bevorzugten Ausführungsform der Erfindung ist die Vertiefung als umlaufende Ringnut im Isolierkörper ausgebildet, was einfach und kostengünstig herstellbar ist. Dabei sind, wie bereits ausgeführt, die Oberkappe und die Hilfskappe im Bereich derselben Vertiefung verformt bzw. in Richtung zu der Vertiefung eingedrückt, wobei, vorzugsweise, sich die Mantelfläche der Oberkappe im Bereich der Vertiefung über die Mantelfläche der Hilfskappe hinaus in Längsrichtung des Isolierkörpers erstreckt und wobei der Verformungsbereich der Oberkappe zumindest auch in einem von der Hilfskappe nicht überdeckten Bereich der Vertiefung vorgesehen ist. Diese Art der formschlüssigen Verbindung ermöglicht es, daß zunächst die Hilfskappe auf den Isolierkörper aufgesetzt und zur Ausbildung eines formschlüssigen Verbundes verformt wird, wobei beispielsweise die Hilfskappe bereichsweise in die Vertiefung gedrückt werden kann. Anschließend kann dann die Oberkappe auf die Hilfskappe aufgesetzt werden, und zwar so weit, daß sich die Mantelfläche der Oberkappe über die Mantelkappe der Hilfskappe hinaus erstreckt. In dem sich über die Mantelfläche der Hilfskappe hinaus erstreckenden Bereich wird dann die Oberkappe verformt, vorzugsweise zumindest bereichsweise in dieselbe Vertiefung gedrückt, so daß es zur Ausbildung einer formschlüssigen Verbindung zwischen der Oberkappe und dem Isolierkörper kommt.In a preferred embodiment of the invention, the recess is formed as a circumferential annular groove in the insulating body, which is simple and inexpensive to produce. In this case, as already stated, the top cap and the auxiliary cap in the region of the same depression deformed or pressed in the direction of the recess, wherein, preferably, the lateral surface of the top cap extends in the region of the recess over the lateral surface of the auxiliary cap out in the longitudinal direction of the insulating body and wherein the deformation region of the upper cap is provided at least in a region of the depression which is not covered by the auxiliary cap. This type of positive connection makes it possible that first the auxiliary cap is placed on the insulating body and is deformed to form a positive connection, for example, the auxiliary cap can be partially pressed into the recess. Then then the top cap can be placed on the auxiliary cap, and indeed so far that the lateral surface of the top cap extends beyond the outer cap of the cap. In which over the lateral surface of the auxiliary cap extending beyond the top cap is then deformed, preferably at least partially pressed into the same recess, so that it comes to form a positive connection between the top cap and the insulating body.

Grundsätzlich ist es natürlich auch möglich, daß die Oberkappe und die Hilfskappe übereinander angeordnete Verformungsbereiche aufweisen. Beispielsweise ist es möglich, die Hilfskappe und die Oberkappe in übereinander liegenden Bereichen gemeinsam in eine Nut des Isolierkörpers einzuwalzen, um eine formschlüssige Verbindung zwischen den Kappen und dem Isolierkörper auszubilden. Bei einer alternativen Ausführungsform kann dagegen auch vorgesehen sein, daß Verformungsbereiche der Oberkappe und der Hilfskappe in wenigstens zwei unterschiedlichen Vertiefungen des Isolierkörpers vorgesehen sind. Beispielsweise ist es zur Ausbildung einer eine ausreichende Festigkeit bei hohen Temperaturen gewährleistenden Verbindung zwischen den Kappen und dem Isolierkörper möglich, daß der Verformungsbereich der Hilfskappe im Bereich einer zur Stirnseite des Isolierkörpers näher gelegenen, den Isolierkörper umlaufenden Ringnut und der Verformungsbereich der Oberkappe im Bereich einer zur Stirnseite des Isolierkörpers weiter entfernt gelegenen Ringnut vorgesehen ist.In principle, it is of course also possible that the top cap and the auxiliary cap have superimposed deformation regions. For example, it is possible to co-roll the auxiliary cap and the top cap in superimposed areas in a groove of the insulating body to form a positive connection between the caps and the insulating body. In an alternative embodiment, however, can also be provided that deformation regions of the top cap and the auxiliary cap are provided in at least two different recesses of the insulating body. For example, it is sufficient to form a sufficient strength at high temperatures ensuring connection between the caps and the insulating possible that the deformation of the auxiliary cap is provided in the region of a closer to the end of the insulating body, the insulating body circumferential annular groove and the deformation of the top cap in the region of an end face of the insulating further away located annular groove ,

Die Dichtigkeit der erfindungsgemäßen Anordnung aus Hilfskappe, Oberkappe und Isolierkörper wird durch ein Dichtmittel gewährleistet, das zwischen der Oberkappe und dem Isolierkörper und/oder zwischen der Hilfskappe und dem Isolierkörper vorgesehen ist. Grundsätzlich ist es auch möglich, eine Mehrzahl von Dichtmitteln einzusetzen. Vorzugsweise handelt es sich bei dem Dichtmittel um eine Dichtmanschette und/oder um einen Dichtring. Hier kann vorgesehen sein, daß das Dichtmittel in der Vertiefung des Isolierkörpers festgelegt ist. Im Betriebszustand befindet sich das Dichtmittel dann unterhalb der Verformungsbereiche der Oberkappe und/oder der Hilfskappe zwischen den Kappen und dem Isolierkörper oder auch gegebenenfalls zumindest bereichsweise zwischen den Kappen.The tightness of the inventive arrangement of the auxiliary cap, top cap and insulator is ensured by a sealant, which is provided between the top cap and the insulating body and / or between the auxiliary cap and the insulating body. In principle, it is also possible to use a plurality of sealants. Preferably, the sealing means is a sealing collar and / or a sealing ring. Here it can be provided that the sealing means is fixed in the recess of the insulating body. In the operating state, the sealant is then below the deformation regions of the top cap and / or the auxiliary cap between the caps and the insulating body or optionally at least partially between the caps.

Durch die Anordnung des Dichtmittels in der Vertiefung wird die Lage des Dichtmittels auf dem Isolierkörper festgelegt. Beim Verformungsvorgang der Oberkappe und/oder der Hilfskappe kommt es dabei dazu, daß die Oberkappe und/oder die Hilfskappe gegen das Dichtmittel verformt werden, was bedeutet, daß der Verformungsbereich der Oberkappe und/oder der Hilfskappe das Dichtmittel zusammendrückt. Dadurch wird eine besonders hohe Dichtwirkung des Dichtmittels erzeugt. Zu dem kann vorgesehen sein, daß die Oberkappe und/oder die Hilfskappe in Längsrichtung benachbarte und durch einen nicht verformten Bereich getrennte Verformungsbereiche aufweist. Im Ergebnis wird die Oberkappe und/oder die Hilfskappe mehrfach in getrennten Bereichen verformt, wobei sich das Dichtmittel zwischen den Verformungsbereichen aufwirft und eine Dichtigkeit der Verbindung gewährleistet ist. Die benachbarten Verformungsbereiche der Oberkappe und/oder der Hilfskappe sollten dabei in einem bestimmten Abstand zueinander stehen, der ein Aufwerfen des Dichtmittels zwischen den Verformungsbereichen ermöglicht. Das Dichtmittel weist eine ausreichend hohe Elastizität auf, um im Fall der Ausdehnung der Kappen bei hohen Temperaturen gleichwohl einen sich bildenden Spalt abzudichten und eine sichere kraftschlüssige Verbindung zu gewährleisten.The arrangement of the sealant in the recess, the position of the sealant is set on the insulator. During the deformation process of the upper cap and / or the auxiliary cap, it happens that the upper cap and / or the auxiliary cap are deformed against the sealant, which means that the deformation region of the upper cap and / or the auxiliary cap compresses the sealant. As a result, a particularly high sealing effect of the sealant is produced. It can also be provided that the upper cap and / or the auxiliary cap has longitudinally adjacent deformation regions separated by an undeformed region. As a result, the top cap and / or the auxiliary cap is deformed several times in separate areas, with the sealant between the deformation ranges raised and a tight connection is ensured. The adjacent deformation regions of the top cap and / or the auxiliary cap should be at a certain distance from each other, which allows a raising of the sealant between the deformation regions. The sealant has a sufficiently high elasticity to nevertheless form in the case of expansion of the caps at high temperatures Gap seal and ensure a secure positive connection.

Bei einer weiter bevorzugten Ausführungsform der Erfindung ist es vorgesehen, daß die Oberkappe und die Hilfskappe derart verformt sind, daß sich vorzugsweise über ein Dichtmittel eine formschlüssige Verbindung zwischen der Oberkappe und der Hilfskappe und/oder dem Isolierkörper und/oder zwischen der Hilfskappe und dem Isolierkörper ergibt. Der Erfindung liegt an dieser Stelle die Grundidee zugrunde, durch Anpressen der Hilfskappe und/oder der Oberkappe auf den Isolierkörper, wobei zwischen der Hilfskappe und/oder der Oberkappe und dem Isolierkörper zumindest ein Dichtmittel vorgesehen sein kann, eine formschlüssige Verbindung auszubilden.In a further preferred embodiment of the invention, it is provided that the top cap and the auxiliary cap are deformed such that preferably via a sealing means a positive connection between the top cap and the auxiliary cap and / or the insulating body and / or between the auxiliary cap and the insulating body results. The invention is based on the basic idea at this point, by pressing the auxiliary cap and / or the top cap on the insulating body, wherein between the auxiliary cap and / or the top cap and the insulating body at least one sealing means may be provided to form a positive connection.

Zur Ausbildung einer formschlüssigen Verbindung kann die Hilfskappe im stirnseitigen Bereich der Mantelfläche umgebördelt und/oder die Oberkappe im stirnseitigen Bereich der Mantelfläche in die Vertiefung eingedrückt, vorzugsweise in die Ringnut eingerollt sein. Ist lediglich ein einziger Formschluß-Formvorgang vorgesehen, so ist es möglich, daß die Hilfskappe am Kappenrand und die Oberkappe mittig gleichzeitig von außen angerollt werden. In diesem Fall können übereinander liegende Verformungsbereiche durch gemeinsames Verformen der Hilfskappe und der Oberkappe erhalten werden. Ebensogut ist es möglich, daß in einem Formvorgang die Hilfskappe am Kappenrand und die Oberkappe ebenfalls am Kappenrand gleichzeitig von außen angerollt werden, so daß nach dem Formvorgang die Hilfskappe und die Oberkappe jeweils einen Verformungsbereich aufweisen, die jedoch nicht übereinanderliegend angeordnet sind.To form a positive connection, the auxiliary cap can be crimped in the end region of the lateral surface and / or the top cap pressed into the recess in the frontal region of the lateral surface, preferably rolled into the annular groove. If only a single form-fitting operation is provided, it is possible that the auxiliary cap at the edge of the cap and the upper cap are centrally rolled simultaneously from the outside. In this case, overlying deformation areas can be obtained by co-deforming the auxiliary cap and the top cap. It is equally possible that in a molding operation, the auxiliary cap on the cap edge and the top cap are also rolled on the cap edge simultaneously from the outside, so that after the molding process, the auxiliary cap and the top cap each have a deformation region, which are not arranged one above the other.

Um die in dem Isolierkörper vorgesehene Vertiefung abzudecken, kann vorgesehen sein, daß sich die Mantelfläche der Oberkappe über den Bereich der Vertiefung hinaus erstreckt. Um die Oberkappe in einfacher Weise auf die Hilfskappe aufsetzen zu können, kann weiter vorgesehen sein, daß die Mantelfläche der Oberkappe stirnseitig nach außen aufgeweitet ist.In order to cover the depression provided in the insulating body, it can be provided that the lateral surface of the upper cap extends beyond the region of the depression. In order to put the top cap in a simple manner on the auxiliary cap, can be further provided that the lateral surface of the upper cap is flared frontally outwards.

In Fig. 1 ist eine erste Ausführungsform einer erfindungsgemäßen öldichten Hochspannungssicherung 1 dargestellt, die zum Betrieb bei Temperaturen bis vorzugsweise 150 °C vorgesehen ist. Auf die Hochspannungssicherung 1 ist stirnseitig eine Hilfskappe 3 und auf die Hilfskappe 3 eine Oberkappe 4 aufgesetzt. Dabei wird die Mantelfläche des Isolierkörpers 2 zumindest teilweise im Stirnbereich des Isolierkörpers 2 von der Hilfskappe 3 überdeckt. Die Mantelfläche der Hilfskappe 3 wird gemäß der in Fig. 1 dargestellten Ausführungsform der erfindungsgemäßen Hochspannungssicherung 1 vollständig von der Mantelfläche der Oberkappe 4 überdeckt. Darüber hinaus befindet sich zwischen der Oberkappe 4 und dem Isolierkörper 2 ein Dichtmittel 5, wobei es sich bei den in den Fig. 1 bis 5 dargestellten Ausführungsformen der erfindungsgemäßen Hochspannungssicherung 1 um eine Dichtmanschette handelt.In Fig. 1 a first embodiment of an inventive oil-tight high-voltage fuse 1 is shown, which is intended for operation at temperatures up to preferably 150 ° C. On the high-voltage fuse 1, an auxiliary cap 3 is placed on the front side and an upper cap 4 is placed on the auxiliary cap 3. In this case, the lateral surface of the insulating body 2 is at least partially covered in the front region of the insulating body 2 of the auxiliary cap 3. The lateral surface of the auxiliary cap 3 is according to the in Fig. 1 illustrated embodiment of the high-voltage fuse 1 according to the invention completely covered by the lateral surface of the upper cap 4. In addition, located between the top cap 4 and the insulating body 2, a sealant 5, wherein it is in the in the Fig. 1 to 5 illustrated embodiments of the high-voltage fuse 1 according to the invention is a sealing sleeve.

Nicht im einzelnen dargestellt ist, daß die Hilfskappe 3 über Verbindungslaschen mit Anschlußkappen eines im Inneren des Isolierkörpers 2 vorgesehenen Schmelzleiters elektrisch kontaktiert sein kann. Im Einbauzustand ist die Oberkappe 4 ihrerseits mit der Hilfskappe 3 elektrisch kontaktiert, wobei die elektrische Kontaktierung nach außen vorzugsweise direkt über die Mantelfläche der Oberkappe 4 erfolgt.It is not shown in detail that the auxiliary cap 3 can be electrically contacted via connecting straps with connecting caps of a fuse conductor provided in the interior of the insulating body 2. In the installed state, the upper cap 4 in turn is electrically contacted with the auxiliary cap 3, wherein the electrical contact to the outside preferably takes place directly over the lateral surface of the upper cap 4.

Um bei hohen Temperaturen von in der Regel oberhalb 100 °C bis 150 °C eine öldichte Abdeckung des im Betriebszustand mit Sand gefüllten keramischen Isolierkörpers 2 durch die Oberkappe 4 zu gewährleisten, ist es erfindungsgemäß vorgesehen, daß die Hilfskappe 3 derart gegenüber dem Isolierkörper 2 verformt ist, daß sich eine formschlüssige Verbindung mit dem Isolierkörper 2 ergibt. Bei dem in Fig. 1 dargestellten Ausführungsbeispiel ist die Mantelfläche der Hilfskappe 3 bereichsweise am äußeren Rand in Richtung zur Mittellängsachse des Isolierkörpers 2 umgebogen, wobei der beim Umbiegen gebildete Verformungsbereich 7 der Hilfskappe 3 in den Innenbereich einer umlaufenden Nut 8 des Isolierkörpers 2 eingreift. Dabei ist es so, daß der Verformungsbereich 7 gegen eine Schulter 9 des Isolierkörpers 2 anliegt, wodurch eine formschlüssige Verbindung zwischen der Hilfskappe 3 und dem Isolierkörper 2 ausgebildet wird.In order to ensure at high temperatures of usually above 100 ° C to 150 ° C, an oil-tight cover of the operating state with sand-filled ceramic insulating body 2 through the top cap 4, it is inventively provided that the auxiliary cap 3 so deformed relative to the insulating body 2 is that results in a positive connection with the insulating body 2. At the in Fig. 1 illustrated embodiment, the lateral surface of the auxiliary cap 3 is partially bent at the outer edge in the direction of the central longitudinal axis of the insulating body 2, wherein the formed during bending deformation region 7 of the auxiliary cap 3 engages in the inner region of a circumferential groove 8 of the insulating body 2. It is such that the deformation region 7 abuts against a shoulder 9 of the insulating body 2, whereby a positive connection between the auxiliary cap 3 and the insulating body 2 is formed.

Das Dichtmittel 5 seinerseits ist in der Nut 8 festgelegt und liegt gegen die Stirnseite der Hilfskappe 3 im Verformungsbereich 7 an. Um die auf die Hilfskappe 3 vorzugsweise reibschlüssig aufgesetzte Oberkappe 4 formschlüssig mit der Hilfskappe 3 zu verbinden, ist weiter vorgesehen, daß durch Einwalzen bzw. Einrollen der Oberkappe 4 in die Nut 8 zwei weitere Verformungsbereiche 10, 11 der Oberkappe 4 vorgegeben werden, durch die es über das Dichtmittel 5 zur Ausbildung einer formschlüssigen Verbindung mit der Hilfskappe 3 kommt. Zwischen dem Dichtmittel 5 und der Oberkappe 4 wird so zudem eine kraftschlüssige Verbindung erzeugt. Wesentlich bei der in Fig. 1 dargestellten Ausführungsform ist, daß der Verformungsbereich 7 der Hilfskappe 3 und die weiteren Verformungsbereiche 10, 11 der Oberkappe 4 in dieselbe Nut 8 des Isolierkörpers 2 eingreifen. Dabei kommt es durch die Verformung der Oberkappe 4 zu einem Zusammenpressen des Dichtmittels 5, was die Dichtigkeit der Verbindung erhöht. Wenngleich in Fig. 1 die Oberkappe 4 und die Hilfskappe 3 im Bereich derselben Nut 8 verformt sind, ist es grundsätzlich natürlich auch möglich, daß Verformungsbereiche 7, 10, 11 der Oberkappe 4 und der Hilfskappe 3 in voneinander getrennten Vertiefungen des Isolierkörpers erzeugt werden, vorzugsweise durch Einwalzen oder Einrollen.The sealing means 5 in turn is fixed in the groove 8 and abuts against the end face of the auxiliary cap 3 in the deformation region 7. In order to positively connect the cap 3 preferably frictionally patch upper cap 4 with the auxiliary cap 3 is further provided that by rolling or curling the top cap 4 in the groove 8 two further deformation regions 10, 11 of the top cap 4 are set by the it comes about the sealant 5 to form a positive connection with the auxiliary cap 3. Between the sealant 5 and the top cap 4 so a non-positive connection is also generated. Essential in the Fig. 1 illustrated embodiment that the deformation region 7 of the auxiliary cap 3 and the other deformation regions 10, 11 of the upper cap 4 engage in the same groove 8 of the insulating body 2. It comes by the deformation of the top cap 4 to a compression of the sealant 5, which increases the tightness of the connection. Although in Fig. 1 the upper cap 4 and the auxiliary cap 3 are deformed in the same groove 8, it is of course also possible that deformation regions 7, 10, 11 of the upper cap 4 and the auxiliary cap 3 are generated in separate recesses of the insulating body, preferably by rolling or rolling ,

In Fig. 2 ist eine weitere Ausführungsform einer erfindungsgemäßen Hochspannungssicherung dargestellt, wobei die Oberkappe 4 und die Hilfskappe 3 übereinander liegende Verformungsbereiche 7, 10 aufweisen. Hierzu ist es vorgesehen, daß die Hilfskappe 3 am Kappenrand und die Oberkappe 4 mittig gleichzeitig von außen eingerollt werden können. Die Verformungsbereiche 7, 10 sind somit durch gemeinsames Verformen der Hilfskappe 3 und der Oberkappe 4 erhältlich. Darüber hinaus ist es gleichzeitig oder auch anschließend zum gemeinsamen Formvorgang der Hilfskappe 3 und der Oberkappe 4 möglich, den weiteren Verformungsbereich 11 der Oberkappe 4 durch Einrollen der Oberkappe 4 zu erzeugen.In Fig. 2 a further embodiment of a high-voltage fuse according to the invention is shown, wherein the upper cap 4 and the auxiliary cap. 3 have superimposed deformation regions 7, 10. For this purpose, it is provided that the auxiliary cap 3 at the edge of the cap and the top cap 4 can be centrally rolled from the outside at the same time. The deformation regions 7, 10 are thus obtainable by jointly deforming the auxiliary cap 3 and the upper cap 4. In addition, it is simultaneously or subsequently to the common molding process of the auxiliary cap 3 and the top cap 4 possible to generate the further deformation region 11 of the top cap 4 by rolling the top cap 4.

Die in Fig. 3 dargestellte Detailansicht zeigt eine Verbindung bei einer alternativen Ausführungsform einer erfindungsgemäßen Hochspannungssicherung 1, wobei die Oberkappe 4 im weiteren Verformungsbereich 10 weniger stark verformt ist als im weiteren Verformungsbereich 11. Im weiteren Verformungsbereich 10 kommt es zu einer formschlüssigen Verbindung mit dem Verformungsbereich 7 der Hilfskappe 3. Im Ergebnis wird dadurch das Dichtmittel 5 unterhalb der Verformungsbereiche 7, 10 einerseits und unterhalb des Verformungsbereiches 11 andererseits mit einem im wesentlichen gleichen Anpreßdruck beaufschlagt, was zu einer gleichmäßigen Belastung des Dichtmittels führt.In the Fig. 3 shown detail shows a connection in an alternative embodiment of a high-voltage fuse 1 according to the invention, wherein the upper cap 4 is deformed less in the further deformation region 10 than in the further deformation region 11. In the further deformation region 10, there is a positive connection with the deformation region 7 of the auxiliary cap. 3 As a result, the sealing means 5 is subjected under the deformation regions 7, 10 on the one hand and below the deformation region 11 on the other hand with a substantially equal contact pressure, resulting in a uniform loading of the sealant.

Die Fig. 4 bis 5 betreffen weitere Möglichkeiten, eine Verbindung zwischen der Oberkappe 4, der Hilfskappe 3 und dem Isolierkörper 2 auszubilden. Gemäß Fig. 4 weist die Oberkappe 4 lediglich einen weiteren Verformungsbereich 10 auf, der relativ zur benachbarten Stirnseite des Isolierkörpers 2 seitlich neben dem Verformungsbereich 7 der Hilfskappe 3 angeordnet ist. Der Verformungsbereich 7 der Hilfskappe 3 ist gegen das Dichtmittel 5 verformt und führt zu einer Stauchung des Dichtmittels 5 in diesem Bereich. Bei der in Fig. 5 dargestellten Möglichkeit, eine kraftschlüssige Verbindung zwischen der Oberkappe 4, der Hilfskappe 3 und dem Dichtmittel 5 bzw. eine formschlüssige Verbindung mit dem Isolierkörper 2 auszubilden, ist vorgesehen, daß die Oberkappe 4 und die Hilfskappe 3 jeweils am Mantelaußenrand in Richtung zum Isolierkörper 2 umgebogen sind. Der Verformungsbereich 7 der Hilfskappe 3 und der weitere Verformungsbereich 10 der Oberkappe 4 greifen in die Nut 8 des Isolierkörpers 2 ein, wobei der Isolierkörper 2 unterschiedliche Wandstärken auf beiden Seiten der Nut 8 aufweist. Die Dichtigkeit zwischen der Hilfskappe 3 bzw. der Oberkappe 4 und dem Isolierkörper 2 wird wiederum durch ein Dichtmittel 5 gewährleistet.The 4 to 5 relate to other ways to form a connection between the top cap 4, the auxiliary cap 3 and the insulating body 2. According to Fig. 4 the upper cap 4 only has a further deformation region 10, which is arranged laterally adjacent to the deformation region 7 of the auxiliary cap 3 relative to the adjacent end side of the insulating body 2. The deformation region 7 of the auxiliary cap 3 is deformed against the sealant 5 and leads to a compression of the sealant 5 in this area. At the in Fig. 5 illustrated possibility to form a frictional connection between the top cap 4, the auxiliary cap 3 and the sealing means 5 or a positive connection with the insulating body 2, it is provided that the top cap 4 and the auxiliary cap 3 are each bent at the outer edge of the casing in the direction of the insulating body 2 , The deformation region 7 of the auxiliary cap 3 and the further deformation region 10 of the upper cap 4 engage in the groove 8 of the insulating body 2, wherein the insulating body 2 has different wall thicknesses on both sides of the groove 8. The tightness between the auxiliary cap 3 and the upper cap 4 and the insulating body 2 is again ensured by a sealant 5.

In den Fig. 6 bis 7 sind Detailansichten erfindungsgemäßer Verbindungen zwischen der Oberkappe 4, der Hilfskappe 3 und dem Isolierkörper 2 dargestellt, wie sie bei alternativen Ausführungsformen der erfindungsgemäßen Hochspannungssicherung 1 vorgesehen sein können. Gemäß den Fig. 6 und 7 sind jeweils zwei Dichtmittel 5 vorgesehen, beispielsweise O-Ringe. Bei der in Fig. 6 dargestellten Ausführungsform ist es so, daß das der Schulter 9 der Nut 8 benachbarte Dichtmittel 5 zwischen dem Isolierkörper 2 und der Hilfskappe 3 angeordnet ist. Das zweite Dichtmittel 5 ist unterhalb des Verformungsbereiches 7 der Hilfskappe 3 zwischen dem Isolierkörper 2 und dem weiteren Verformungsbereich 10 der Oberkappe 4 vorgesehen, wobei das zweite Dichtmittel 5 durch den Verformungsbereich 10 der Oberkappe 4 gestaucht wird. Damit wird die Dichtigkeit auch bei höheren Temperaturen gewährleistet.In the 6 to 7 are detailed views of inventive compounds between the top cap 4, the auxiliary cap 3 and the insulating body 2 shown, as they may be provided in alternative embodiments of the high-voltage fuse 1 according to the invention. According to the 6 and 7 Each two sealing means 5 are provided, for example, O-rings. At the in Fig. 6 illustrated embodiment, it is such that the shoulder 9 of the groove 8 adjacent sealing means 5 is disposed between the insulating body 2 and the auxiliary cap 3. The second sealing means 5 is provided below the deformation region 7 of the auxiliary cap 3 between the insulating body 2 and the further deformation region 10 of the top cap 4, wherein the second sealing means 5 is compressed by the deformation region 10 of the top cap 4. This ensures tightness even at higher temperatures.

Schließlich weist gemäß der Fig. 5 sowie der Fig. 7 der Isolierkörper 2 auf der von der benachbarten Stirnseite des Isolierkörpers 2 abgewandten Seite der Nut 8 jeweils eine Wandstärke auf, die im wesentlichen der Gesamtwandstärke entspricht, die sich aus der Wandstärke des Isolierkörpers 2 im Stirnbereich des Isolierkörpers 2 und der Wandstärke der Hilfskappe 3 ergibt. Dadurch ist es möglich, die Oberkappe 4 im wesentlichen spaltfrei so weit auf den Isolierkörper aufzuschieben, daß die Nut 8 vollständig überdeckt ist.Finally, according to the Fig. 5 as well as the Fig. 7 the insulating body 2 on the side facing away from the adjacent end face of the insulating body 2 side of the groove 8 each have a wall thickness which substantially corresponds to the total wall thickness, resulting from the wall thickness of the insulating body 2 in the end region of the insulating body 2 and the wall thickness of the auxiliary cap 3. This makes it possible to postpone the upper cap 4 substantially gap-free so far on the insulator that the groove 8 is completely covered.

Wie der obigen Beschreibung von bevorzugten Ausführungsformen der erfindungsgemäßen Hochspannungssicherung 1 zu entnehmen ist, geht die Erfindung einen völlig neuen Weg, wobei, vorzugsweise, die Hilfskappe 3 und die Oberkappe 4 relativ zu einer Vertiefung des Isolierkörpers 2 zur Ausbildung einer kraft- und formschlüssigen Verbindung eingedrückt oder eingerollt sind und wobei der Verformungsbereich 7 der Hilfskappe 3 mit zumindest einem weiteren Verformungsbereich 10, 11 der Oberkappe 4 und zumindest einem Dichtmittel 5 zusammenwirkt. Vorzugsweise ist es dabei vorgesehen, daß die Hilfskappe 3 und die Oberkappe 4 in dieselbe Vertiefung, vorzugsweise eine umlaufende Ringnut 8 des Isolierkörpers 2, eingerollt sind. Dadurch wird eine formschlüssige Verbindung mit dem Isolierkörper zur Verfügung gestellt, die es ermöglicht, die erfindungsgemäße Hochspannungssicherung 1 auch bei hohen Temperaturen einzusetzen, ohne daß ein Abheben der Hilfskappe 3 und/oder der Oberkappe 4 von dem Isolierkörper 2 und damit ein Verlust der Öldichtigkeit bei erhöhten Temperaturen befürchtet werden muß. Darüber hinaus kann es nicht dazu kommen, daß bei einer Ausdehnung der Kappen 3, 4 bei hohen Temperaturen Öl in die Sicherung 1 eindringt, da durch das Dichtmittel 5 eine ausreichende Abdichtung des Isolierkörpers 2 zu jedem Zeitpunkt gewährleistet ist. Dazu ist es notwendig, daß das Dichtmittel eine ausreichende Elastizität aufweist.As the above description of preferred embodiments of the high-voltage fuse 1 according to the invention can be seen, the invention is a completely new way, wherein, preferably, the auxiliary cap 3 and the top cap 4 is pressed relative to a recess of the insulating body 2 to form a non-positive and positive connection or are rolled up and wherein the deformation region 7 of the auxiliary cap 3 with at least one further deformation region 10, 11 of the upper cap 4 and at least one sealing means 5 cooperates. Preferably, it is provided that the auxiliary cap 3 and the top cap 4 in the same recess, preferably a circumferential annular groove 8 of the insulating body 2, are rolled. As a result, a positive connection with the insulating body is provided, the it makes it possible to use the high-voltage fuse 1 according to the invention even at high temperatures, without any need to fear a lifting of the auxiliary cap 3 and / or the top cap 4 of the insulating body 2 and thus a loss of oil tightness at elevated temperatures. In addition, it can not happen that at an expansion of the caps 3, 4 at high temperatures oil penetrates into the fuse 1, as is ensured by the sealing means 5, a sufficient sealing of the insulating body 2 at any time. For this it is necessary that the sealant has sufficient elasticity.

Im übrigen läßt es die Erfindung bedarfsweise zu, die anhand der Fig. 1 bis 7 beschriebenen Merkmale erfindungsgemäßer Hochspannungssicherungen 1 zu kombinieren, auch wenn dies nicht im einzelnen beschrieben ist.Moreover, it allows the invention, if necessary, based on the Fig. 1 to 7 to combine described features of inventive high voltage fuses 1, although this is not described in detail.
