Description
<Desc/Clms Page number 1>
Phasensehutzrelais.
EMI1.1
<Desc/Clms Page number 2>
EMI2.1
(Leerlaufleistung) ab der Fall ein, dass das Drehmoment der Stromtriebe über jenes des Drehfeldmessers und der Torsionsfeder überwiegt. Es wird also das Relais bei dieser Unsymmetrie bei allen Leistungen, die grösser sind als Li ansprechen und die Maschine.. vom Netz abtrennen.
Endlich soll das Phasenschutzrelais im Falle einphasigen Kurzschlusses ansprechen. Bei einphasigem Kurzschluss kehrt der Drehfeldmesser seine Drehmomentrichtung um. Das Relais schlägt wieder an den Anschlag ban, R spricht an und schaltet den Motor vom Netz ab.
PATENT-ANSPRUCHE :
1. Stromrelais zum Schutze gegen einphasigen oder unsymmetrischen Betrieb mehrphasiger
EMI2.2
drehmoment der Strommesser grösser wird, als dasjenige des Drehfeldmessers.

EMI2.1
(Idle power) from the case that the torque of the current drives outweighs that of the rotary field meter and the torsion spring. With this asymmetry, the relay will respond to all powers that are greater than Li and disconnect the machine .. from the mains.
Finally the phase protection relay should respond in the event of a single-phase short circuit. In the event of a single-phase short circuit, the rotary field meter reverses its torque direction. The relay hits the ban stop again, R responds and disconnects the motor from the mains.
PATENT CLAIMS:
1. Current relay for protection against single-phase or asymmetrical multi-phase operation
EMI2.2
torque of the ammeter is greater than that of the rotary field meter.
