Description

Elektrodynamische Meßgeräte, deren Anzeige aus dem Zusammenwirken mehrerer Einzelmeßwerke resultiert, z. B. Wattmeter, können wegen der gegenseitigen Beeinflussung der einzelnen Meßwerke nur mit einer verhältnismäßig geringen Klassengenauigkeit hergestellt werden. Um diese Beeinflussung möglichst klein zu halten, ordnet man die auf eine gemeinsame Achse wirkenden einzelnen Meßwerke in möglichst weitem Abstand an. Bereits bei Ausführungen niederer Klassengenauigkeit erhält man dadurch eine erhebliche Bauhöhe des Gerätes. Diese wird untragbar bei Geräten höherer Klassengenauigkeit.Electrodynamic measuring devices, their display from the interaction several single measuring units results, z. B. wattmeter, may because of mutual Influence of the individual measuring mechanisms only with a relatively low class accuracy getting produced. In order to keep this influence as small as possible, one arranges the individual measuring mechanisms acting on a common axis as far apart as possible at. This gives you a considerable height of the device. This becomes intolerable with devices of higher class accuracy.

Zur Verrneidung dieses Übelstandes werden die in der Achsenrichtung aufeinanderfolgenden Einzelmeßwerke erfindungsgemäß jeweils um go Winkelgrade gegeneinander verdreht angeordnet. Dadurch werden die aufeinanderfolgenden magnetischen Flüsse zueinander senkrecht orientiert, und ihre gegenseitige Beeinflussung wird auf ein Mindestmaß zurückgeführt. So gelangt man bei tragbarer Bauhöhe zu erheblich gesteigerter Klassengenauigkeit.To avoid this inconvenience, the in the axial direction successive single measuring units according to the invention in each case by go angular degrees against each other arranged twisted. This causes the successive magnetic fluxes oriented perpendicular to each other, and their mutual influence is on one Minimum measure returned. In this way, with a portable construction height, you get a considerably higher one Class accuracy.

Die Abbildung zeigt das Meßwerkgerippe ohne oberste Abschlußplatte und ohne die festen Spulen. a ist die untere Abschlußplatte, in der sich auch das untere Lager für das bewegliche System befindet. b und c sind Zwischenplatten, deren Zahl sich nach der Anzahl der vereinten Einzelmeßwerke richtet. d sind Streben, die die Platten miteinander verbinden. Die obere Abschlußplatte, an der die Brücke mit der oberen Achsenlagerung sowie die Dämpfungskammer und die Skala angeordnet sind, ist der Deutlichkeit wegen nicht mitgezeichnet. e ist das bewegliche Organ mit den drei Drehspulen f, g und h. Während f und h in gleicher Richtung stehen, ist die Spule g zu dieser Richtung um go Winkelgrade versetzt. Die Platten b und c haben so große Innenbohrungen, daß das fertigmontiertebewegliche Organ durch sie eingeführt werden kann. i sind die Zylinderstürnpfe zur Führung der Halteplatten für die festen Spulen, die bei der oberen Abdeckplatte nach unten, bei der unteren nach oben und bei den Zwischenplatten b und c sowohl nach unten als auch nach oben hervorragen. Die festen Spulen sind ebenfalls der Deutlichkeit wegen nicht rnitgezeichnet.The figure shows the measuring mechanism frame without the top end plate and without the fixed coils. a is the lower end plate, which also houses the lower bearing for the moving system. b and c are intermediate plates, the number of which depends on the number of combined individual measuring units. d are struts that connect the plates together. The upper end plate, on which the bridge with the upper axle bearing as well as the damping chamber and the scale are arranged, is not shown for the sake of clarity. e is the movable organ with the three moving coils f, g and h. While f and h are in the same direction, the coil g is offset from this direction by go degrees. The plates b and c have inner bores so large that the fully assembled movable member can be inserted through them. i are the cylinder throats for guiding the holding plates for the fixed bobbins, which protrude downwards on the upper cover plate, upwards on the lower cover plate and upwards and downwards on the intermediate plates b and c. The fixed coils are also not shown for the sake of clarity.
