Description
Drehstrom-Transformator, insbesondere zur Stromlieferung für elektrische Schweißeinrichtungen Für Schweißzwecke ist bekanntlich die günstigste Stromart der Gleichstrom. Da aber in sehr vielen Fällen nur Drehstrom zur Verfügung steht, macht es sich erforderlich, ein Aggregat, bestehend aus Drehstrom-Transformator und Gleichrichter, aufzustellen. Die Regelung der jeweilig benötigten Schweißstromstärken- erfolgt durch den Transformator, der hierfür als besonderer Streu-Transformator ausgebildet sein muß.Three-phase transformers, in particular for supplying electrical power Welding equipment As is well known, the cheapest type of current for welding purposes is the Direct current. But since in many cases only three-phase current is available, makes it is necessary to install a unit consisting of a three-phase transformer and rectifier, to set up. The regulation of the respectively required welding amperage takes place by the transformer, which is designed as a special leakage transformer for this purpose have to be.
Es sind Drehstrom-Transformatoren mit beweglichen und zwecks Änderung der Streuung verstellbaren Streujochen bekannt. Derartige Anordnungen haben aber den Nachteil, daß das verstellbare Joch zu Geräuschbildungen Anlaß geben kann; außerdem ist die Erkrichtung zur Verstellung des Joches nun sehr ürnständlich für Fernbedienung einzurichten. Weiterhin ist auch ein Einphasen-Transformator mit fest angebautem Streujoch bekannt, auf dem eine regelbare Wicklung angeordnet ist. Dieser Transformator läßt sich aber nicht ohne weiteres als Drehstrom-Transformator umbauen. Die Erfindung setzt sich nun zum Ziele, die Vorteile des fest eingebauten Strenjoches mit der auf ihm angeordneten Reglerwicklung bei Drehstrom-Transformatoren zur Anwendung zu bringen.They are three-phase transformers with moving and changing purpose the spreading adjustable Streujochen known. However, such arrangements have the disadvantage that the adjustable yoke can give rise to noise; aside from that the installation for adjusting the yoke is now very cumbersome for remote control set up. Furthermore, there is also a single-phase transformer with a permanently attached Streujoch known, on which an adjustable winding is arranged. This transformer but cannot easily be converted into a three-phase transformer. The invention now aims to combine the advantages of the built-in Strenjoch with the Regulator winding arranged on it for use in three-phase transformers bring to.
Zu dem Zweck wird ein Drehstrom-Trans formatür, insbesondere zur Stromlieferung für elektrische Schweißeinrichtungen mit zwischen Primär- ünd Sekundärwicklung legendem Streujoch, in der Weise ausgebildet, daß gemäß der Erfindung nvischen den auf den drei Transformatorenkerien angeordneten getrennten Primär- und Sekundärgricklungen. feste, die Kerne magnetisch verkettende und vorzugsweise mechanisch verbindende Streujoche eingebaut sind, auf denen in. an sich bekannter Weise 'Wicklungen angebracht und an einen Regelwiderstand angeschlossen sind.A three-phase transformer is used for this purpose, especially for supplying electricity for electrical welding equipment with between primary and secondary winding Streujoch, designed in such a way that according to the invention nvischen to the Separate primary and secondary windings arranged in three transformer series. fixed, the cores magnetically linked and preferably mechanically connecting Streujoche are built in, on which windings are attached in a manner known per se and are connected to a rheostat.
Diese Anordnung hat den Vorteil des. einfachen mechanischen Aufbaues und gestattet ferner eine bequeme Regelung der Schweißstromstärke, falls erforderlich, sogar durch Fernbedienung.This arrangement has the advantage of a simple mechanical structure and also allows convenient control of the welding current strength, if necessary, even by remote control.
Die Abbildung zeigt ein Ausführungsbeispiel des Erfindungsgedankens. a ist der Transformatorkern, auf dessen drei Schenkeln die Primärwicklungen b und die Sekundärwicklungen c .aufgebracht sind. Zwischen Primär= und Sekundärwicklung ist das feste Zwischenjochd mit der Wicklung e angeordnet. Diese Wicklung ist durch den Regelwiderstand f- überbrückt.The figure shows an embodiment of the inventive concept. a is the transformer core, on whose three legs the primary windings b and the secondary windings c. are applied. Between primary = and secondary winding the fixed intermediate yoke is arranged with the winding e. This winding is through the rheostat f- bridged.
Ist der volle Widerstand/ in den Wicklungskreis des Zwischenjoches d eingeschaltet, so ist die maximale Streuwirkung vorhanden. In dem Maße, wie der Regelwiderstand f verringert wird, vermindert sich :durch die magnetische Rückwirkung der Wicklungen auf die Streujoche deren Streuwirkung. Durch die Anbringung des bewickelten Zwischenjoches-d ist man also in der Lage, auf rein elektrischem Wege in einfachster Weise die Streuwirkung des Transformators und damit die Schweißstromstärken in jedem gewünschten Umfang zu regeln.Is the full resistance / in the winding circuit of the intermediate yoke d switched on, the maximum scattering effect is available. To the extent that the The rheostat f is reduced: by the magnetic reaction of the windings on the scattering effect. By attaching the wrapped Zwischenjoches-d is therefore able to operate in a purely electrical manner in the simplest possible way Way the scattering effect of the transformer and therefore the welding currents in each to regulate the desired scope.
