Claims (1)

<Desc/Clms Page number 3> <Desc / Clms Page number 3> 2. Überstromabhängiger Primärauslöser nach Anspruch 1, dadurch gekennzeichnet, dass das fehlerortsempfindliche Organ energierichtungsempfindlich ist und die von der Netzspannung abhängige Hilfsgrö- sse kapazitiv auf den Primärauslöser übertragen wird. 2. Overcurrent-dependent primary release according to claim 1, characterized in that the fault location-sensitive organ is energy direction sensitive and the auxiliary variable dependent on the mains voltage is capacitively transferred to the primary release. 3. Überstromabhängiger Primärauslöser nach Anspruch l, dadurch gekennzeichnet, dass für die kapazitive Übertragung der von der Netzspannung abhängigen Hilfsgrösse ein Teil der Primärauslöseverschalung als Kondensatorbelag benützt wird. EMI3.1 Netzspannung abhängige Hilfsgrösse von einer an Erdpotential liegenden Sendevorrichtung elektromagnetisch auf den Primärauslöser übertragen wird. 3. Overcurrent-dependent primary release according to claim l, characterized in that part of the primary release casing is used as a capacitor layer for the capacitive transmission of the auxiliary variable which is dependent on the mains voltage. EMI3.1 Mains voltage dependent auxiliary variable is transmitted electromagnetically to the primary release by a transmitting device connected to earth potential. 5. Überstromabhängiger Primärauslöser nach Anspruch l, dadurch gekennzeichnet, dass die von der Netzspannung abhängige Hilfsgrösse über einen hochohmigen Widerstand auf den Primärauslöser übertragen wird. 5. Overcurrent-dependent primary release according to claim l, characterized in that the auxiliary variable dependent on the mains voltage is transmitted to the primary release via a high-resistance resistor. 6. Überstromabhängiger Primärauslöser nach Anspruch l, dadurch gekennzeichnet, dass die von der Netzspannung abhängige Hilfsgrösse mechanisch über ein elektrisch isolierendes Gestänge auf den Primärauslöser übertragen wird. 6. Overcurrent-dependent primary release according to claim l, characterized in that the auxiliary variable dependent on the mains voltage is transmitted mechanically to the primary release via an electrically insulating linkage. 7. Überstromabhängiger Primärauslöser nach Anspruch l, dadurch gekennzeichnet, dass die zur Speisung des Auslösesperrorganes und der fehlerortsempfindlichen Organe notwendige Energie einem Transformator entnommen wird, dessen Magnetkern wenigstens teilweise im Felde der Hauptstromwicklung liegt. 7. Overcurrent-dependent primary release according to claim l, characterized in that the energy necessary to feed the release blocking element and the fault location-sensitive organs is taken from a transformer whose magnetic core is at least partially in the field of the main current winding.
