Claims (1)
Patentanspruch:Claim:Einrichtung zur Überwachung der Polarität asynchron anlaufender Einankerumformer,
dadurch gekennzeichnet, daß ein an die Gleichstrombürsten des Umformers angeschlossenes unpolarisiertes Zeitrelais
mit vongeschaltetem Gleichrichter eine bestimmte Zeit nach dem Eintritt der richtigen
Polarität anspricht und dadurch den Anlaßvongang zu Ende führt.Device for monitoring the polarity of asynchronous starting single-armature converters,
characterized in that an unpolarized time relay connected to the DC brushes of the converter
with the rectifier switched on for a certain time after the correct one has occurred
Responds to polarity and thereby brings the starting process to an end.*) Von dem Patetitsucher ist als der Erfinder angegeben worden:*) The patetite seeker stated as the inventor:Botho Fleck in Berlin-Steglitz.Botho Fleck in Berlin-Steglitz.
