Description
Γ-ig. 3 ist der gcsar .!■■ Schall widerstand dargestellt, der aus einem Stapel aufeinander geschichteter Wider sundssebeiben besieht und in einen hohlen zylindrischen Isolator eingesetzt ist.Γ-ig. 3 is the gcsar.! ■■ Sound resistance shown, the sundssebeiben from a stack of stacked opponents and into a hollow one cylindrical insulator is used.
In Fig. I ist gezeigt, wie der Strom / in die Kontaktstelle 2 hineinfließt, die Metallstege 4 mäanderartig durchfließt und aus der Kontaktteile 3 v,i?dei· abtritt. Anschließend fließt der Strom in umgekehrter Richtung durch die der Widerstandsscheibe 1 benachbarte Scheibe (nicht gezeichnet). Die Widcrstandsscheiben 1 sind durch Ausstanzen aus einem Blech hciߣii/?!h.In Fig. I it is shown how the current / flows into the contact point 2, the metal webs 4 meandering flows through and from the contact parts 3 v, i? dei resigns. The current then flows in reverse Direction through the disk adjacent to the resistance disk 1 (not shown). The resistance disks 1 are made by punching out of a sheet metal hciß £ ii / ?! h.
Der gegenseitige Kontakt der aufeinander geschichteten Widerstandsscheiben kann noch dadurch verbessert werden, daß die Kontaktstellen 2, 3 mit herausgedrückten Sicken 12, 13 versehen sind. Durch die Sicken wird der Abstand zwischen den einzelnen Widerstandsscheiben 1, der durch die gegenseitige Isolierung 11 erzeugt wird, an den Kontaktstellen 2, 3 überbrückt. Ks können weiterhin auch die Stege 4 zur Versteifung mit Längssicken 5 versehen werden, wodurch sich die Stabilität der Widerstandsscheiben erhöht und die aufeinander gestapelten Widerstand·· scheiben vor dem seitlichen Verrutschen gesichert werden können.The mutual contact of the resistance disks stacked on top of one another can thereby be further improved be that the contact points 2, 3 are provided with depressed beads 12, 13. By the beads will be the distance between the individual resistance washers 1, which is due to the mutual Isolation 11 is generated at the contact points 2, 3 bridged. Ks, the webs 4 can also be provided with longitudinal beads 5 for stiffening, which increases the stability of the drag disks and the stacked resistors panes can be secured against slipping sideways.
Die Widerstandsscheiben 1 können zweckmäßig an ihren Kontaktstellen 2, 3 eine Zinn- oder Silberauflagc mit einer Stärke von 20—50 μ aufweisen.The resistance disks 1 can expediently have a tin or silver coating at their contact points 2, 3 with a thickness of 20-50 μ.
F i g. 2 zeigt, daß die Widerstandsscheiben /weckmäßig auch spiralförmig ausgestanzt sein können. Auch hier tritt der Strom z. B. an der Kontaktstelle 2 ein. durchfließt die Leiterbahn 4 und geht über die Kontaktstelle 3 zum benachbarten Element über. Zur Erzielung einer geringen Gesamtinduklivität sind die Widerstandsscheiben dabei so angeordnet, daß der Windungssinn von Scheibe zu Scheibe wechselt.F i g. 2 shows that the resistance disks / wake-up can also be punched out spirally. Here, too, the current occurs z. B. at contact point 2 a. flows through the conductor track 4 and passes over the contact point 3 to the adjacent element. To the To achieve a low overall inductivity, the resistance disks are arranged so that the Winding sense changes from disc to disc.
In Fig. 3 ist zu erkennen, daß die Widcrslandsschcibcn 1 zu einem Stapel 6 aufeinander geschichtet sind und zweckmäßig mittels senkrecht durch Öffnungen 7 hindurchgesteckter keramischer Stifte 8 gegen seitliches Verschieben gesichert sind.In Fig. 3 it can be seen that the Widcrslandsschcibcn 1 are layered on top of one another to form a stack 6 and expediently by means of perpendicularly through openings 7 ceramic pins 8 inserted through them are secured against lateral displacement.

Die Zwischenliigcn können dabei zweckmäßig aus ü.'L1Wi unter hohem Druck verformbaren Isolierrnaitn,,! bestehen.The Zwischenliigcn can expediently from 1 ü.'L Wi deformable under high pressure Isolierrnaitn ,,! exist.
Die Mäanderblechscheiben können dann in ihrer Kontur in den Isolierstoff eingepreßt werden, wodurch eine seitliche Verschieblichkeit unter dem Einfluß der Stromstärke vermieden werden kann. Dieser Effekt lüLU sich durch in das Blech eingedrückte Sicken verstärken, die in vorgeformte entsprechende Nuten int Isolierstoff eingreifen. Eine derartige Ausbildung eignet sich auch als Montageerleichterung.The contour of the meandering sheet metal disks can then be pressed into the insulating material, as a result of which a lateral displacement under the influence of the current intensity can be avoided. This effect lüLU are reinforced by corrugations pressed into the sheet metal, which are made of insulating material in corresponding pre-formed grooves intervention. Such a training is also suitable to facilitate assembly.
Weiterhin können zweckmäßig auch Zwischenlagen verwendet werden, die zu den Sicken der Widerstandsseheiben passend vorgeprägt sind. Auch hierdurch wird das Verrutschen des Plattenstapels verhindert.Furthermore, intermediate layers can expediently be used, which form the beads of the resistance washers are pre-stamped to match. This also prevents the stack of plates from slipping.
Der gesaniie Stapel 6 aus Widerstandsscheiben 1 und gegebenenfalls Isolierzwischenlagen Ii .st zweckmäßig in einen hohlen zylindrischen Isolator 9 eingesetzt und durch mindestens eine Tellerfeder 10 zusammenpreßbar. Dabei trägt der Preßdruck einige Mp. Die elastische Pressung hat gegenüber einer Verschraubung den Vorteil, d.,3 die Ausdehnung des Stapels infolge seiner Erwärmung ausgeglichen wird.The whole stack 6 of resistance disks 1 and If necessary, insulating interlayers Ii .st expedient inserted into a hollow cylindrical insulator 9 and compressible by at least one plate spring 10. The compression pressure carries a few Mp. The elastic compression has the opposite to a screw connection Advantage, i.e., 3 the expansion of the stack as a result of its heating is compensated.
Der Isolator 9 ist zweckmäßig mit Schwefelhexafluorid (SFf,) gefüllt. Hierdurch wird die Isolierung des Plattensiapels verbessert und die Gefahr innerer Überschläge bei Widerständen für sehr hohe Spannungen beseitigt.The insulator 9 is expediently filled with sulfur hexafluoride (SFf,). This will isolate the Plattensiapels improved and the risk of internal flashovers in the case of resistors for very high voltages eliminated.
Eine temperaturabhängige Kühlung des Plattenstapels durch strömende Druckluft ist notwendig, wenn
mehrere, kurz aufeinanderfolgende Schaltungen durchgeführt werden müssen. Hierzu weist zweckmäßig der
Isolator 9 einen durch ein Ventil abgeschlossenen Einströmkanal für die Kühlluft auf. und das Ventil läßt
sich durch einen mit den Widerstandsscheiben
Wärmekontakt stehenden Bimetallstreifen öffnen.A temperature-dependent cooling of the plate stack by flowing compressed air is necessary if several switching operations in quick succession have to be carried out. For this purpose, the insulator 9 expediently has an inflow channel closed by a valve for the cooling air. and the valve can be through one with the resistance disks
Open bimetal strips that are in contact with heat.
