PATENTANSPRÜCHE:PATENT CLAIMS: 1. Einrichtung zum Schutz der Überschaltwiderstände von Lastschaltern für die stufenweise Schneilumschaltung von Stelltransformatoren unter Verwendung von Überstromrelais, welche beim Auftreten von Überströmen im Transformatorstromkreis den Stufenstellantrieb stillsetzen, dadurch gekennzeichnet, daß durch die Überstromrelais die Schaltspule eines Motorschutzschalters gesteuert wird.1. Device to protect the transfer resistances of load switches for the gradual Fast switching of variable transformers using overcurrent relays, which in the event of overcurrents in the transformer circuit, the step actuator shut down, characterized in that the switching coil of a Motor protection switch is controlled. 2. Vorrichtung nach Anspruch i, dadurch gekennzeichnet, daß der Motorschutzschalter mittels einer Nullspannungsspule zum Abschalten gebracht wird und daß das Einschalten desselben von Hand vorgenommen wird.2. Apparatus according to claim i, characterized characterized in that the motor protection switch is switched off by means of a zero voltage coil is brought and that it is switched on by hand. 3. Vorrichtung nach Anspruch 1, dadurch gekennzeichnet, daß sowohl das Abschalten als auch das Wiedereinschalten des Motorschutzschalters automatisch in Abhängigkeit von den Kontakten der Überstromrelais vorgenommen wird.3. Apparatus according to claim 1, characterized in that both the shutdown as also the restart of the motor protection switch automatically depending on the Contacts of the overcurrent relay is made.
