Differentialrelais mit zwei Spulen nach Art der Fig. 1 werden so lange im Gleichgewicht bleiben, als die Wirkungen der beiden Spulen einander gleich sind, gleichgültig, wie grofs die Wirkung absolut genommen ist; das Gleichgewicht wird nur dann gestört, wenn die Wirkung der beiden Spulen ungleich wird. Solche Differentialrelais sind bekannt und werden z. B. in Dreileitersystemen verwendet, um anzuzeigen, wenn die Spannung auf der einen Seite des Dreileitersystems' verschieden ist von der Spannung der anderen Seite desselben (Fig. 1).Differential relays with two coils of the type of FIG. 1 are so long in equilibrium remain, as the effects of the two coils are equal to one another, no matter how great they are Effect is taken in absolute terms; the equilibrium is only disturbed when the effect of the two coils becomes unequal. Such differential relays are known and are z. B. used in three-wire systems to indicate when the voltage is on one side of the Three-wire system 'is different from the voltage on the other side of the same (Fig. 1).
Vorliegende Erfindung hat eine ähnliche Vorrichtung zum Gegenstande; sie unterscheidet sich jedoch von den bereits bekannten Einrichtungen dadurch, dafsThe present invention is directed to a similar device; she distinguishes however, differs from the already known devices in that
ι. mehr als zwei Spulen vorhanden sind,ι. there are more than two coils,
2. der bewegliche Körper d um jede beliebige , durch g gehende waagrechte Achse drehbar ist (Fig. 2 und 3).2. the movable body d is rotatable about any horizontal axis going through g (FIGS. 2 and 3).
Infolge dessen ist die vorliegende Einrichtung geeignet, bei Mehrphasensystemen, deren verschiedene Zweige beim gewöhnlichen Betrieb gleiche oder nahezu gleiche Ströme führen, Leitungsbrüche anzuzeigen, indem im Falle eines Leitungsbruches das Gleichgewicht gestört wird.As a result, the present device is suitable in multi-phase systems, their various During normal operation, branches carry the same or almost the same currents, Display line breaks by disrupting the balance in the event of a line break will.
Beim Dreiphasensystem z. B. werden die drei Ströme Z1 Z2 Z3 um drei Spulen S1 s.2 S3 mit gleichen Windungszahlen geleitet und diese Spulen in den Eckpunkten eines gleichseitigen Dreiecks d angeordnet. In jede Spule taucht ein Eisenkern k. Die drei Kerne Ar1 U2 ks sind in den Ecken eines gleichseitigen Dreiecks d aufgehängt, welches in seinem Schwerpunkt g unterstützt ist. Das Gleichgewicht ist nur so lange vorhanden, als die drei Spulen von gleichen Strömen umflossen werden. Dasselbe wird jedoch gestört, sobald ein Leitungsdraht reifst, also ein Strom Null wird. Das Dreieck neigt sich und setzt gleichzeitig eine in dem Maschinenhaus befindliche Lärmvorrichtung in Thätigkeit.In the three-phase system z. B. the three currents Z 1 Z 2 Z 3 are passed around three coils S 1 s. 2 S 3 with the same number of turns and these coils are arranged in the corner points of an equilateral triangle d . An iron core k is immersed in each coil. The three cores Ar 1 U 2 k s are suspended in the corners of an equilateral triangle d , which is supported in its center of gravity g . The equilibrium is only present as long as the three coils are surrounded by equal currents. However, the same thing is disturbed as soon as a conductor wire matures, i.e. a current becomes zero. The triangle inclines and at the same time activates a noise device located in the machine house.
Für Zweiphasenanlagen mit drei Leitungen findet der Apparat ebenfalls Verwendung. Dabei ist nur die Windungszahl derjenigen Spule, die vom Strom ■ des Mittelleiters umflossen .wird , zu ändern , nämlich gleich s/1,4 zu nehmen, wenn s die Windungszahl der beiden anderen Spulen ist.The device is also used for two-phase systems with three lines. Only the number of turns of the coil around which the current ■ from the center conductor flows must be changed, namely to be equal to s / 1.4 if s is the number of turns in the other two coils.
