Es sind Überspannungsableiter vorgeschlagen worden, bei denen ein in Reihe mit einem Hörnerableiter liegender Dämpfungswiderstand zu einem Teil kurzgeschlossen ist und die Kurzschließung des Teilwiderstandes erst dann aufgehoben wird, wenn nach Ansprechen des Ableiters der Überspannungswelle die Energie im wesentlichen entzogen ist. Beim Einschalten des ganzen Widerstandes in den ίο Erdungsstromkreis wird der Lichtbogen amThere have been proposed surge arresters in which one in series with a Horn conductor lying damping resistance is short-circuited to a part and the short-circuit of the partial resistance only is canceled when, after the surge arrester has responded, the Energy is essentially withdrawn. When switching on the whole resistor in the ίο Earth circuit will cause the arc to occur
. Hörnerableiter zum Erlöschen gebracht. Die Überbrückung und Einschaltung des Teilwiderstandes erfolgt durch einen Schalter, der von einer Spule beherrscht wird, die im Erdungsstromkreis liegt oder von ihm abgezweigt ist. Bei anderen Überspannungsschutzeinrichtungen dieser Art (Patentschrift 243809) wird die Funkenstrecke nach dem Ansprechen durch einen Schalter kurzgeschlossen und dadurch der entstandene Licht- ao bogen ausgelöscht.. Horn conductor extinguished. The bridging and activation of the partial resistance is done by a switch that is dominated by a coil that is im Earth circuit is or is branched from it. With other overvoltage protection devices of this type (patent specification 243809), the spark gap is short-circuited by a switch after it has responded and thereby the resulting arc is extinguished.

fließende Energie setzt sich in Wärme um, die heim oftmaligen. Ansprechen sich zu gefahrdrohender Höhe,'Steigern, kann.flowing energy is converted into heat, the home often. Address themselves to dangerous heights, 'increase, can.
Um die damit verbundene Gefahr zu vermeiden, wird nach der Erfindung dafür gesorgt, daß bei zu starker Erwärmung des Öls die Umsetzung von 'Energie in Wärme !«schränkt wird. Das geschieht dadurch, daß der den Teilwiderstand oder die Funkenstrecke kurzschließende Schalter bei Überschreiten einer gewissen zulässigen Temperatur des Öles in der Offenstellung selbsttätig mechanisch verriegelt wird.To avoid the associated danger, according to the invention it is ensured that if the oil is heated too much, the conversion of 'energy into heat ! «Is restricted. This happens because the partial resistance or the spark gap short-circuiting switch when a certain permissible temperature of the oil is exceeded in the open position automatically is mechanically locked.
In der Abbildung ist die Erfindung an einem Ausführungsbeispiel erläutert, dem die erstgenannte Schutzeinrichtung zugrunde gelegt ist. x\ls Wärmemesser wird dabei ein Zweimetallstreifen benutzt, natürlich läßt sich das gleiche Ziel auch mit anderen Mitteln erreichen.In the figure, the invention is explained using an exemplary embodiment to which the the first-mentioned protective device is used. x \ ls calorimeter will be a Two-metal strips used, of course, the same goal can be achieved by other means reach.
Der Schalter <· überbrückt den Teilwider standW1. Im Kessel ist der Zweimetallstreifen e angeordnet, der in kaltem Zustand1 die punktierte Lage einnimmt. Überschreitet die öltemperatur das infolge häufigen Ansprechens der Schutzeinrichtung zulässige Maß, so nimmt der Zweimetallstreifen die ausgezogen dargestellte Lage ein. Wenn jetzt eine Überspannungswelle von der Leitung σ über den Hörnerableiter b und den Widerstand W2 zur Erde geleitet ν,ύτά, so spricht die Spule d an und der Hebel des Schalters c verriegelt sich an dfcr Nase des Zweimetallstreifens e. The switch <bridges the partial resistance W 1 . The two-metal strip e is arranged in the boiler and assumes the dotted position in the cold state 1. If the oil temperature exceeds the permissible level due to frequent response of the protective device, the bimetal strip assumes the position shown in solid lines. If an overvoltage wave is now conducted from the line σ via the horn arrester b and the resistor W 2 to earth ν, ύτά, the coil d responds and the lever of the switch c locks on the nose of the two-metal strip e.
Dann ist der Widerstand W1 in den Erdungsstromkreis eingeschaltet, und zwar so lange, bis die Temperatur des Öles wieder zurückgeht und der Zweimetallstreifen sich nach links durchbiegt.Then the resistor W 1 is switched into the grounding circuit, until the temperature of the oil drops again and the two-metal strip bends to the left.
Während der Verriegelung des Schalters c in der Offenstellung können Überspannungswellen immer nach der Erde fließen, wenn auch über einen höheren Widerstand.While switch c is locked in the open position, surge waves can always flow to earth, albeit through a higher resistance.
Der Körper /, an welchem der Zweimetallstreifen e befestigt ist, kann etwa nach Lösen einer Schraube g gedreht und dann wieder festgestellt werden. Hierdurch ist es möglich, die Temperatur, bei welcher die Verriegelung des Schalters c erfolgen soll, beliebig z. B. nach einer Skala einzustellen.The body / to which the two-metal strip e is attached can be rotated, for example after loosening a screw g , and then locked again. This makes it possible to set the temperature at which the switch c is to be locked, any z. B. set according to a scale.
