ErfindungPATENT ANSPRÜCHE : 1. Kurzschliess- und bzw. oder Überwachungsschalter zum Schutze von vorzugsweise als Funkenstrecken ausgebildeten Spannungsableitern gegen Überlastung durch Fremdspannungen bei Blitzeinschlägen, Berührung mit Hochspannungsleitungen u. dgl., dadurch gekennzeichnet, dass ein an sich bekannter magnetisch durch einen im oder parallel zum Magnetkreis liegenden Steuerkörper (St) aus einem Werkstoff temperaturabhängiger magnetischer Induktion steuerbarer Schalter (R) als Kurzschliess- und bzw. oder Überwachungsschalter vorgesehen ist, und dass der Steuerkörper (St) thermisch über einen Leiter mit geringer wirksamer Selbstinduktivität, vorzugsweise über einen bifilar gewickelten, von dem den Spannungsableiter (FS) durchfliessenden Ableitstrom beeinflussbar ist. InventionPATENT CLAIMS: 1. Short-circuit and / or monitoring switch to protect voltage arresters, preferably designed as spark gaps, against overloading by external voltages in the event of lightning strikes, contact with high-voltage lines, etc. The like., characterized in that a known magnetically by a control body (St) located in or parallel to the magnetic circuit made of a material of temperature-dependent magnetic induction controllable switch (R) is provided as a short-circuit and / or monitoring switch, and that the control body (St) thermally via a conductor with a low effective self-inductance, preferably via a bifilar wound, from which the leakage current flowing through the voltage arrester (FS) can be influenced. 2. Schalter nach Anspruch 1, dadurch gekennzeichnet, dass ein Dauermagnet (Da) den Magnetfluss des als polarisiertes Relais ausgebildeten Ruhe- und Arbeitskontakte aufweisenden Magnetschalter (R) erzeugt, wodurch der Anker (A) gegen die Kraft einer Feder (Fe) in seiner einen Endlage verschwenkt gehalten werden kann, und dass der Anker (A) bei Erwärmung des Steuerkörpers (St) von der Feder (Fe) in seiner andern Endlage verschwenkt gehalten wird. 2. Switch according to claim 1, characterized in that a permanent magnet (Da) generates the magnetic flux of the magnetic switch (R) designed as a polarized relay and having normally open contacts, whereby the armature (A) against the force of a spring (Fe) in its one end position can be kept pivoted, and that the armature (A) is kept pivoted in its other end position by the spring (Fe) when the control body (St) is heated. 3. Schalter nach einem der vorhergehenden Ansprüche, dadurch gekennzeichnet, dass der Magnetschalter (R') einen so ausgebildeten mit vier entsprechend ausgebildeten Polschuhen (P1 - P4) zusammen- EMI3.1 3. Switch according to one of the preceding claims, characterized in that the magnetic switch (R ') has a so designed with four appropriately designed pole pieces (P1 - P4) together. EMI3.1
