Description

Überspannungsableiter für Hochspannungsanlagen Zum Zwecke des Schutzes gegen überspännungen werden Fünkenstrecken (Hörnerableiter) angewendet, die unmittelbar oder über einen Widerstand geerdet sind. Um den nach dem Ansprechen der Funkenstrecke an dieser entstandenen Lichtbogen zu löschen, wird die Funkenstrecke durch einen Schalter selbsttätig kurzgeschlossen und dabei über einen Widerstand an Erde gelegt, oder es wird die Kurzschließung eines Teiles des Vorschaltwiderstandes der Funkenstrecke mittels eines Schalters aufgehoben. Es kann nun der Fall eintreten, daß der Schalter z. B. wegen Unterbrechung der Magnetspule des Schalters oder aus irgendeinem Grunde so hängen bleibt, daß dauernd ein starker Strom durch den Widerstand fließt. Es liegt dann die Gefahr vor, daß das C51 der Schutzeinrichtung sich bis zur Entflammungstemperatur erhitzt.Surge arrester for high voltage systems For protection purposes against overvoltage, spark lines (horn arresters) are used, which are directly or are grounded through a resistor. To that after the spark gap has responded to extinguish at this arcing, the spark gap is through a Switches automatically short-circuited and connected to earth via a resistor, or it is the short circuit of part of the series resistor of the spark gap canceled by means of a switch. It can now happen that the switch z. B. due to interruption of the solenoid of the switch or for any reason gets stuck in such a way that a strong current constantly flows through the resistor. It there is then the danger that the C51 of the protective device will reach the ignition temperature heated.

Um die Einrichtung gegen die Folgen des Versagens des Schalters zu schützen, wird nach der- Erfindung in den Stromkreis des parallel zur Funkenstrecke liegenden Schalters bzw. in eine oder beide Zuleitungen zu dem den Teilwiderstand kurzschließenden Schalter eine Sicherung mit verzögernder Wirkung eingeschaltet, die bei unzulässig lange dauerndem Stromdurchgang durchschmilzt und dann den Stromkreis unterbricht oder die Kurzschließung des Teilwiderstandes aufhebt.To protect the facility against the consequences of the breaker failure protect, according to the invention in the circuit of the parallel to the spark gap lying switch or in one or both leads to the partial resistance short-circuiting switch a fuse with a delaying effect is switched on, which melts through the passage of current for an inadmissibly long time and then the circuit interrupts or removes the short-circuiting of the partial resistance.

- Es sind zweckmäßig diese Sicherungen derart zu bemessen, daß sie nach einem niederen Vielfachen der Schaltdauer des Schalters ansprechen.- It is advisable to dimension these fuses in such a way that they respond after a lower multiple of the switching duration of the switch.
