Description
Verfahren zur Herstellung von Trockenwandlern Die Erfindung bezieht sich auf ein Ver fahren zur Herstellung von Trockenwandlern, bei denen der Eisenkern mit, der Unterspan- nungswick11.rng und die Oberspannmigswick- lung in zwei miteinander verkettete Ringkap seln eingeschlossen sind,
die zusammen in einem gemeinsamen Mantel aus Giessharz sit zen und bei denen Armaturteile zum Befesti gen und Anschliessen dies Wandlers vorge sehen sind. Erfindungsgemäss sind diese Ar maturteile in den Mantel miteingegossen. Zweckmässig können auch Metalleinlagen, Schirmringe, die zur Feldsteuerung dienen, muteingegossen werden.
Ebenso können Ab standstücke, die in der Giessform .die verschic denen Teile ' gegeneinander und gegen die Formwand in ihrem Abstand sichern, mitein- gegossen werden. Um an Giessharz zu sparen, kann man vom Feld nicht oder nur schwach beanspruchte Stellen des Mantels durch Ein legen von Kernen in die Giessform mit Hohl- räiun.en versehen. Die miteingegossenen Teile werden am besten aus einem Baustoff herge stellt, dessen Wälmeaus:dehnungsverhältnisse dem des Giessharzes gleichkommen.
Eine besonders einfache und vorteilhafte Ausführungsform :des Verfahrens verwendet die metallischen Beläge zugleich als Kapseln. In der Giessform werden diese Kapseln durch Abstandsstücke gesichert. Die Abstandstücke werden anschliessend miteingegossen. Ein nach diesem. Verfahren gefertigter Stromwandler hat eine besonders kleine und <RTI
ID="0001.0049"> rauansparende Bauform.
An Hand der Zeichnung werden: zwei Alus- führwigsbeispiele von Wandlern, die nach dem erfindungsgemässen Verfahren hergestellt sind, erläutert.
In Fig.l bis 3 sind die Obergpannungs- wicklung 3 sowie die Unterspannimgswieklung 1 mit Eisenkern in zwei kreuzweise mitein ander verketteten Ringkapseln 21., 22 ange ordnet, die von einem Giessharzmantel 4 um hüllt sind. In dem Giessharzmantel sind Arma- turbefestig@ingsteile 6, z.
B. für die Grund platte 7 und den an einer Kappe 8 angeord neten Ableiter 9, miteingegossen. Der Ableiter 9 kann aber auch ausserhalb der Isolierkappe 8 angebaut sein. In .der Grundplatte 7 sind zugleich die Anschlussssteile 10 für die Unter- spannungswicklung 1 eingebaut.
Um dien Giess- harzverbrauch zu verringern, ist der Mantel körper 4 mit Hohlräumen 11 versehen, die durch Einslegen von Giesskernen in die Giess form heigestellt werden. Die Kapseln 21,
22 sind vorteilhaft aus Metall hergestellt und bil- dendamit zugleich Potentialflächen für die Festlegung der Feldverteilung. Zur Steuerung des Feldes im Mantel können sich in ihren Ausdehnungsverhältnissen dem Mantelgiess- ha,
rz gut anpassende Formstücke wie auch Metalleinlagen miteingegossen weeden. Fig. 4 und 5 zeigen ein weiteres Ausfüh- rlmmsbeispiel in zwei Schnitten, wobei die Bezeichnungsziffern mit denen des Ausfüh rungsbeispiels nach Fig. 1 bis 3 gleichbedeu tend sind.
Die Anordnung nach Fig. 4 und 5 zeichnet sich durch besonders sparsamen Giess- hamzverbraiieh aus und, nimmt- auch verhält nismässig wenig Raum in Anspruch. Ausser dem isst, .der Mantel so ausgebildet, dass eine besondere Giaindplatte gespart werden kann. 12 ist eine den untern Kapselraum abdeckende Platte, die an eingegossenen Armaturteilen 6 befestigt ist.
Process for the production of dry converters The invention relates to a process for the production of dry converters in which the iron core, the lower voltage winding and the upper voltage winding are enclosed in two interlinked annular capsules,
which sit together in a common sheath made of cast resin and in which fitting parts are provided for attaching and connecting this converter. According to the invention, these Ar matur parts are cast into the jacket. Metal inserts, shield rings, which are used for field control, can also be mute-cast.
Likewise, spacers, which "secure the various parts" against each other and against the mold wall at their distance in the casting mold, can also be cast. In order to save on casting resin, areas of the jacket that are not or only slightly stressed by the field can be provided with cavities by placing cores in the casting mold. The cast-in parts are best made from a building material with an expansion ratio that is equal to that of the cast resin.
A particularly simple and advantageous embodiment: the method uses the metallic coverings at the same time as capsules. These capsules are secured in the casting mold by spacers. The spacers are then cast in as well. One after this. Process manufactured current transformer has a particularly small and <RTI
ID = "0001.0049"> rough-cut design.
With the aid of the drawing: two aluminum examples of transducers which are manufactured according to the method according to the invention are explained.
In Fig.l to 3, the upper tension winding 3 and the Unterpannimgswieklung 1 with iron core in two crosswise mitein other chained ring capsules 21, 22 are arranged, which are covered by a cast resin jacket 4 to. In the cast resin jacket are armature turbefestig @ ingsteile 6, z.
B. for the base plate 7 and the on a cap 8 angeord designated arrester 9, cast. The arrester 9 can, however, also be installed outside the insulating cap 8. The connection parts 10 for the low-voltage winding 1 are also built into the base plate 7.
In order to reduce the casting resin consumption, the casing body 4 is provided with cavities 11 which are made available by inserting casting cores into the casting mold. The capsules 21,
22 are advantageously made of metal and thus at the same time form potential areas for defining the field distribution. To control the field in the jacket, the jacket casting ha,
Well-fitting fittings as well as metal inserts are also cast in. 4 and 5 show a further exemplary embodiment in two sections, the designation numbers being synonymous with those of the exemplary embodiment according to FIGS. 1 to 3.
The arrangement according to FIGS. 4 and 5 is characterized by particularly economical pouring hamzverbraiieh and, also, takes up relatively little space. Besides eating, the coat is designed so that a special Giaind plate can be saved. 12 is a plate which covers the lower capsule space and which is fastened to cast fitting parts 6.
