Description

Kontrollvorrichtung für Hochspannungslsolatoren und -isolierketten. Die Überwachung der Leitungsanlagen von Hochspannungskraftübertragungen besteht u. a. in einer genauen Besichtigung der Isolatoren auf Haarrisse. Diese Untersuchung setzt eine erhebliche Übung des ausführenden Personals voraus. Es sind auch Meßeinrichtun.gen bekannt geworden, die gestatten, aus der Spannungsverteilung an einer Isolatorkette Störungen zu ermitteln (Meßstangen). Ihre Anwendung setzt auch große Übung voraus und ist außerdem recht zeitraubend.Control device for high voltage isolators and isolating chains. There is monitoring of the line systems of high-voltage power transmissions i.a. in a close inspection of the insulators for hairline cracks. This investigation requires considerable training on the part of the personnel carrying out the work. There are also measuring devices became known that allow from the voltage distribution on an insulator chain To determine disturbances (measuring rods). Their application also requires great practice and is also quite time consuming.

Gegenstand vorliegender Erfindung ist ein Verfahren der Überwachung von Hochspannungsleibungsanligen, das ohne große Übung und Zeitaufwand sichere Resultate ergibt.The present invention relates to a method of monitoring of high-voltage systems, which results in reliable results without much practice or expenditure of time results.

Es beruht darauf, daß beim Durchschlagen und schon kurz vor dem vollständigen Durchschlag die Verteilung der elektrischen Feldstärke an einem. Isolator sich verändert und diese Veränderung durch geeignete Meß- bzw. Anzeigeinstrumente nachgewiesen wird.It is based on the fact that when penetrating and shortly before the complete Breakdown the distribution of the electric field strength at one. Isolator changes and this change is detected by suitable measuring or display instruments will.

Bei Hängeisolatoren wird z. B, zu diesem Zweck zwischen Kette und geerdetem Mast ein Glied eingefügt, das nicht als Hochspanrnungsisolierglied ausgebildet zu sein braucht und daher erheblich billiger als ein solches erstellt werden kann. Die Spannung zwischen Erde und dem Drahtseil (bzw. Klöppel und Kappe), zwischen diesem Glied und. der eigentlichen Isolatorenkette wird sich in dem Augenblick ändern, wo eins der Glieder der Kette durchschlägt. Ebenso kann bei Stützuni Hängeisolatoren eine vom Mast isolierte Traverse benutzt werden. Legt man ein Meßinstrument oder einen Indikator, z. B. eitlen Fernhörer, zwischen Erde .und Drahtseil bzw. Traverse, so läßt sich aus der Angabe des Meßinstrumentes bzw. aus der Lautstärke .des Fernhörers ein Schluß auf den Zustand der Isolierkette ziehen. Eine' entsprechende isolierte Leitung von dem Drahtseil bzw. der isolierten Traverse kann an jedem Mast ohne große Kosten bis im Reichhöhe verlegt werde;, so d#aß die Prüfung ohne Besteigung des Mastes ausgeführt werden kann. Natürlich ist dafür Sorge zu tragen, daß keine gefährlichen Spannungen auftreten können.In suspension insulators z. B, for this purpose between chain and A link is inserted into the grounded mast, which is not designed as a high-voltage insulating link needs to be and can therefore be created much cheaper than such. The tension between earth and the wire rope (or clapper and cap), between this link and. the actual isolator chain will change the moment where one of the links in the chain cuts through. Suspension insulators can also be used for the support uni a traverse isolated from the mast can be used. If you put a measuring instrument or an indicator, e.g. B. vain remote receiver, between earth .und wire rope or traverse, this can be seen from the specification of the measuring instrument or from the volume of the telephone draw a conclusion about the condition of the insulating chain. A 'corresponding isolated Line from the wire rope or the isolated traverse can be attached to any mast without major Costs are moved up to the Reichhöhe; so the test without climbing the Mastes can be run. Of course, care must be taken that there are no dangerous Tensions can occur.

Handelt es stich um: eine Drehstromleitung, so lassen sich die drei isolierten Leitungen zu einer vereinigen. Da die Summe der Spannungen eines Drehstromsystems in jedem Augenblick gleich Null ist, wird dann bei normalem Zustand der drei zusammengehörigen Isolatoren .das Meßinstrument bzw. der Indikator spannungs- bzw. stromlos sein, bis auf evtl, höhere harmonische, die leicht von dem Grundton unterschieden werden können. Nur in .dem Fall, daß an dem Isolator eine Störung auftritt,- tritt eine Spannung bzw. ein Strom auf. Abb. z zeigt als Ausführungsbeispiel diese Anordnung an einer Hochspannungsdrehstromleitung mit Hängeisolatoren und isoliertem Prüfleiter sowie mit Kontaktvorrichtung K am Mast zum Anschluß des Meßinstrumentes bzw. des Indikators, Abb. a die Anordnung bei Stützisolatoren an den bekannten Lyratraversen mit isolierter Traverse nach Anspruch 3 und q..If it is a question of: a three-phase line, the three can be unite isolated lines into one. As the sum of the voltages of a three-phase system is equal to zero at any moment, then in the normal state of the three belonging together Isolators .the measuring instrument or the indicator must be de-energized or de-energized, except for possibly higher harmonics, which can be easily distinguished from the keynote can. Only in the event that a fault occurs in the isolator does one occur Voltage or a current. Fig. Z shows this arrangement as an exemplary embodiment on a high-voltage three-phase current line with suspension insulators and an insulated test conductor as well as with contact device K on the mast for connecting the measuring instrument or the Indicator, Fig. A the arrangement of post insulators on the known Lyra traverses with insulated traverse according to claim 3 and q ..

Natürlich lassen sich die Meßleitungen nach Bedarf zu Gruppen zusammenfassen, so daß eine zentrale Überwachung möglich wird.Of course, the measuring lines can be combined into groups as required, so that central monitoring is possible.
