Description
Stromrichter mit verdampfbarer Kathode Die Erfindung betrifft einen Stromrichter mit verdampfbarer Kathode, Hilfsanode und durch einen steuerharen. Innenzünder, insbesondere einen Stromrichter, der in für Zwecke der Schweißtechnik bestimmten Gleichrichteranlagen verwendet wird, die mit verhältnismäßig kleinen Wechselspannungen betrieben werden.Converters with Vaporizable Cathode The invention relates to a Power converter with vaporizable cathode, auxiliary anode and a taxhare. Internal igniter, in particular a converter, which is used in welding technology certain rectifier systems are used with relatively small AC voltages are operated.
Bei Stromrichteranlagen der vorerwähnten Art kommt es vor, daß die Zündung bei Spannungen beispielsweise unter ioo V Schwierigkeiten macht. Bei solchen Anlag-en wird außerdem die Zündeinrichtung, insbesondere bei Verwendung von Innenzündern (Zünder aus Widerstandswerkstoff), so stark beansprucht, daß sie mitunter schon nach verhältnismäßig kurzer Betriebszeit unbrauchbar ist.In converter systems of the aforementioned type, it happens that the Ignition at voltages below 100 V, for example, makes difficulties. In such The ignition device is also installed, especially when using internal igniters (Detonator made of resistance material), so heavily stressed that it sometimes already is unusable after a relatively short operating time.
Gemäß der vorliegenden Erfindung werden Stromrichter der vorerwähntQn Art dadurch verbessert, daß die zwischen der Anode und der Kathode des Stromrichters angeordnete Hilfsanode an die Anode des Steuerrohres angeschlossen ist. Derartige Stromrichter bieten den Vorteil, daß die Hilfsanode die Zündung zur Hauptanode erleichtert und den durch den Innenzünder fließenden Strom, derdurch das Steuerrohr geht, zum Löschen bringt. Da die Hilfsanode hierbei den Strom übernimmt, sorgt sie dafür, daß der Innenzünder stromlos und so geschont wird.According to the present invention, power converters of the aforementioned Qn Kind improved by the fact that between the anode and the cathode of the converter arranged auxiliary anode is connected to the anode of the control tube. Such Converters offer the advantage that the auxiliary anode facilitates the ignition to the main anode and the current flowing through the internal igniter and passing through the control tube to the Delete brings. Since the auxiliary anode takes over the current, it ensures that the internal igniter is de-energized and thus protected.
In der Zeichnung ist ein Ausfühxungsbeispiel dargestellt. Das Stromrichtergefäß i hat eine Anode 2 und eine Kathode 3. Die Erregerelektrode ist mit 4 bezeichnet und der Innenzünder bei 5 angedeutet. Der Inn#enzünder ist mit der Kathode 6 eines Steuerrohres 7 verbunden, dessen Gitter8 an Steuerspannung liegt, ge- gebenenfalls unter Vorschaltung einer Phasenregelvorrichtung. Die Anode 9 ist mit der Erregerelektrode 4 an den Widerstand io angeschlossen, der seinerseits an dem Transformator i i liegt, mit dem die Kathode 3 verbunden ist. Die Primärwicklung 12 des Transformators i i liegt an einem Wechselstromnetz. Bei 13 ist ein Verbraucher vorgesehen.An exemplary embodiment is shown in the drawing. The converter vessel i has an anode 2 and a cathode 3. The exciter electrode is denoted by 4 and the internal igniter is indicated by 5. The Inn # is enzünder connected to the cathode 6 of a control pipe 7, which is located on Gitter8 control voltage, If appropriate under prescreening of a phase control device. The anode 9 is connected with the excitation electrode 4 to the resistor io, which in turn is connected to the transformer ii to which the cathode 3 is connected. The primary winding 12 of the transformer ii is connected to an alternating current network. At 13 a consumer is provided.
Die neue Gleichrichteranlage bietet folgende Vorteile: Es wird ein auch bei Gleichrichtern geringer Spannung zuverlässiges Zünden erzielt. Der Innenzünder wird durch die stets geringe Strombelastung geschont. Das Steuerrohr kann verhältnismäßig klein gehalten werden, da es nur den erst-en ZUndstoß zu liefern hat und der größte Teil des Stromes selbst übler die Hilfselektrode geht.The new rectifier system offers the following advantages: It becomes a Reliable ignition achieved even with low voltage rectifiers. The internal igniter is protected by the always low current load. The head tube can be proportionate can be kept small, since it only has to deliver the first impulse and the largest Part of the current itself goes worse the auxiliary electrode.
