Description
Durchführungs-Schleifentvandler Die Erfindung betrifft einen Durchfühxungs-Schleifenwandler, bei dem erfindurt`gsgemäß der äußere Bogen eines im wesentlichen gleiche Wandstärke aufweisenden, nach oben offenen, U-förmig gestalteten, aus keramischen oder anderen Isolierstoffen bestehenden Isolierkörpers, der zur Aufnahme des größten Teils der Primärwicklung vorzugsweise rechteckigen Querschnitt besitzt, in einen isolatorähnlichen Fortsatz ausläuft.Bushing loop converter The invention relates to a bushing loop converter, In the case of the invention, the outer arch has a wall thickness that is essentially the same having, upwardly open, U-shaped, made of ceramic or other Insulating materials existing insulating body, which is used to accommodate most of the Primary winding preferably has a rectangular cross section, in an insulator-like Extension runs out.
Bekannt sind Anordnungen für Topfwandler, bei denen ebenfalls der äußere Bogen eines im wesentlichen gleiche Wandstärke aufweisenden, nach oben offenen, U-förmig gestalteten Isolierkörpers zur Aufnahme des größten Teils der Primärwicklung dient und der vorzugsweise rechteckigen Querschnitt besitzt.Arrangements for pot transducers are known, in which also the outer arch of an essentially equal wall thickness, open at the top, U-shaped insulating body to accommodate most of the primary winding serves and preferably has a rectangular cross-section.
Durch die erfindungsgemäße Ausbildung dieser bekannten Wandler, durch Anordnung eines isolatorähnlichen Fortsatzes ist ein Durchführungs-Schleifenwandler geschaffen, der gegenüber den bekannten Durchführungswandlern die Vorzüge aufweist, daß der primäre Ohmsche und induktive Spannungsabfall bedeutend, auf etwa die Hälfte, herabgedrückt sind.The inventive design of these known transducers by Arrangement of an isolator-like extension is a feed-through loop converter created, which has the advantages over the known bushing converters that the primary ohmic and inductive voltage drop is significant, to about half, are depressed.
Die Abbildungen lassen ein Ausführungsbeispiel des Erfindungsgedankens erkennen, und zwar zeigt Abb. i den Durchführungs-Schleifenwandler im Aufrißschnitt; Abb.2 zeigt denselben Wandler in Ansicht von unten. Mit a ist der U-förmige, in .einen isolatorähnlichen Fortsatz auslaufende Isolierkörper bezeichnet, der vorzugsweise rechteckigen Querschnitt hat und mit genügend starken Abrundungen versehen ist. Hierdurch wird eine gleichmäßige Beanspruchung des Isoliermaterials erhalten. b ist die Primärwicklung, c die Sekundän#,icklung, d der Eisenkern. Die Teile der Fassung werden durch Pressen auf dem Isolierkörper festgehalten. Die innere Fläche des Isolierkörpers sowie die äußere von unterhalb der Wulste ä ab kann metallisiert oder graphitiert werden, um die elektrische Beanspruchung ausschließlich in das Isoliermaterial zu legen.The figures leave an embodiment of the inventive concept Fig. i shows the feedthrough loop transducer in elevational section; Fig. 2 shows the same converter from below. With a is the U-shaped, in .an insulator-like extension denotes terminating insulating body, which is preferably has a rectangular cross-section and is rounded off sufficiently. This results in a uniform stress on the insulating material. b is the primary winding, c the secondary winding, d the iron core. The parts of the Sockets are held on the insulating body by pressing. The inner surface of the insulating body as well as the outer from below the beads ä can be metallized or graphitized in order to transfer the electrical stress exclusively into the Laying insulation material.
Der Wandler kann zur Erhöhung der Meßgenauigkeit oder zur Erreichung einer bestimmten überstromcharakteristik usw. mit zwei oder mehreren übereinander oder auf gegenüberliegenden Schenkeln verteilt angeordneten Eisenkernen mit Sekundärwicklungen versehen werden, die entsprechend den an sie gestellten Forderungen bemessen sind.The converter can be used to increase the measurement accuracy or to achieve it a certain overcurrent characteristic etc. with two or more one above the other or iron cores with secondary windings distributed on opposite legs which are measured according to the demands placed on them.
