Description

Vorrichtung zum Ausgleich der Phasenbelastungen in den Leitungen von mehrphasigem Wechselstrom, der einen Kessel vermittels verstellbarer und für jede Phase besonderer Elektroden beheizt. Die Erfindung betrifft eine Vorrichtung zum Ausgleich der Phasenbelastungen in den Leitungen von mehrphasigem Wechselstrom, der einen Kessel vermittels verstellbarer und für jede Phase besonderer Elektroden beheizt und besteht darin, daß zur Veränderung der Kesselleistung nur die Elektroden einer einzigen Phase durch äußere Einwirkung, z. B. durch einen Regler, verstellt werden, während diejenigen der anderen Phasen durch die Differentialwirkung des Stromes der betreffenden Phasen und desjenigen der zuerst durch äußere Einwirkung verstellten Elektroden eingestellt werden.Device for balancing the phase loads in the lines of polyphase alternating current, which means a boiler adjustable and for each Heated phase of special electrodes. The invention relates to a device for Compensation of the phase loads in the lines of multi-phase alternating current, one boiler by means of adjustable electrodes that are special for each phase heated and consists in the fact that to change the boiler output only the electrodes a single phase by external influence, e.g. B. adjusted by a controller while those of the other phases are affected by the differential action of the Current of the phases concerned and that of the first by external influence adjusted electrodes.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt.An embodiment of the invention is shown in the drawing.

a sind die Elektodengehäuse eines nicht gezeichneten, mit Drehstrom beheizten Dampfkessels; b und bl sind die festen, c und cl die beweglichen, durch Servomotore d eingestellten Elektroden und u, v und w die Leitungen der zugehörigen Phasen. Durch die Steuerkolben-g und g1 können die Servomotore z. B. mittels Drucköl, welches durch fein-, durch e ausgelassen wird, in Tätigkeit gesetzt und damit die Elektroden einander genähert oder voneinander entfernt werden. Die Steuerkolben g1 werden durch die Differentialelektromagnete h verstellt und der Steuerkolben g durch einen z. B. vom Dampfverbrauch beeinflußten Regler r. Die eine Spule der Differentialelektromagnete h wird vom Strom der zur Elektrode c gehörenden Phase v und die andere Spule vom Strom der eigenen Phase durchflossen. Wird die Elektrode c mittels Servomotors und Steuerkolbens g von ihrer Gegenelektrode b entfernt, so nimmt der Strom der Phase v stärker ab als derjenige der Phasen u und w. Seine Wirkung in den Differentialelektromagneten h wird von derjenigen der betreffenden Phasenströme überwogen. Infolgedessen werden die Servomotore der Phasen u und w durch ihre Steuerkolben so beeinflußt, daß die daranhängenden Elektroden so lange voneinander entfernt werden, bis die Ströme aller Phasen wieder gleich stark geworden sind. Das Umgekehrte findet statt, wenn die Elektrode c in entgegengesetzter Richtung bewegt wird.a are the electrode housings of a steam boiler, not shown, heated with three-phase current; b and bl are the fixed electrodes, c and cl the movable electrodes set by servomotors d, and u, v and w the leads of the associated phases. Through the control piston g and g1, the servomotors can, for. B. by means of pressure oil, which is omitted by fine, by e, set in action and so that the electrodes are brought closer to each other or away from each other. The control piston g1 are adjusted by the differential electromagnet h and the control piston g by a z. B. influenced by the steam consumption controller r. One coil of the differential electromagnet h is traversed by the current of the phase v belonging to the electrode c and the current of its own phase flows through the other coil. If the electrode c is removed from its counter electrode b by means of the servomotor and control piston g, the current of phase v decreases more than that of phases u and w. Its effect in the differential electromagnet h is outweighed by that of the relevant phase currents. As a result, the servomotors of phases u and w are influenced by their control pistons in such a way that the electrodes attached to them are removed from one another until the currents of all phases have become equally strong again. The reverse takes place when the electrode c is moved in the opposite direction.

Die Servomotore d können mit oder ohne Rückführung ausgerüstet sein. Sie können ferner, je nach Anlage und Zweckmäßigkeit, entweder hydraulisch, wie beschrieben, pneumatisch, elektrisch oder sonstwie betrieben werden.The servomotors d can be equipped with or without feedback. You can also, depending on the system and expediency, either hydraulically, such as described, pneumatically, electrically or otherwise operated.
