Description

Anordnung zur laststromabhängigen Steuerung von gittergesteuerten Entladungsgefäßen, insbesondere mit Dampf- oder Gasfüllung, in Umformerschaltungen Beim Betrieb von gittergesteuerten. Entladungsgefäßen, inshesondere mit Dampf- oder Gasfüllung, in Umformerschaltungen ist es erwünscht, die Gittersteuerung den betrieblichen Notwendigkeiten entsprechend zu be-'einflussen. Solange !ein Entladungsgefäß ord- ° nungs!gem.äß arbeitet, werden .sich bei der Durchbildung der Gittersteuerung entsprechend den betrieblichen Notwendigkeiten keine grundsätzlichen Schwierigkeiten ergeben. Häufig wird nun aber verlangt, daß auch bei reicht ordnungsmäßigem Betrieb wenigstens einzelner Entladungsgefäße, also beispielsweise bei Rückzündungen, die Gittersteuerung in vorbestimmter Weise beeinflußt werden soll. In erster Linie kommen hierbei stromabhängige Steuerungen in Frage. Solche Steuerungen, bei denen beispielsweise ein vom Anodenstrom durchflossener Scheinwiderstand oder Stromwandler verwendet werden kann, sind an sich bekannt. Es hat sich nun aber gezeigt, daß Falschsteuerungen auftreten können. Bei der Verwendung eines Stromwandlers kann. z. B. die Zusatzspannung zur Verhütung des überregelns dienen. Beim Auftreten von Rückzündungen würde jedoch die Zusatzspannung in falscher Richtung steuern.Arrangement for load current-dependent control of grid-controlled Discharge vessels, in particular with vapor or gas filling, in converter circuits When operating grid-controlled. Discharge vessels, especially with steam or Gas filling, in converter circuits, it is desirable to operate the grid control To influence needs accordingly. As long as a discharge vessel is According to what works, they will be implemented accordingly when the grid control is implemented the operational necessities do not result in any fundamental difficulties. Often, however, it is now required that at least if the system is operating properly individual discharge vessels, for example in the event of reignition, the grid control is to be influenced in a predetermined manner. In the first place there are current-dependent ones Controls in question. Such controls in which, for example, an anode current Impedance resistance or current transformer through which it flows are on known. It has now been shown, however, that incorrect controls can occur. When using a current transformer,. z. B. the additional tension for contraception serve to overregulate. However, if re-ignition occurs, the additional voltage would steer in the wrong direction.

Man kann zwar zur Behebung dieser Schwierigkeiten mitunter mechanische Regler oder Schaltorgane, z. B. polarisierte Relais, verwenden. jedoch wird man mechanische Relais beim Betrieb von ruhenden Umformern mit gittergesteuerten Entladungsgefäßen möglichst vermeiden, da die mechanische Trägheit die Betriebsführung erschwert. Man wird nach Möglichkeit zu .rein elektrischen, also trägheitslos arbeitenden Anordnungen übergehen und 'kann dann betriebliche Vorgän e sozusagen schon im Entstehen erfassen. Erfmdungsgemüß kann man dies erreichen, indem in die Verbindung zwischen den Entladungsstromkreisen und den Gitterkreisen gesteuerte Entladungsgefäße mit eindeutiger Stramdurchlaßrichtung derart eingefügt sind, daß den Gitterkreisen eine vom Vorzeichen der stromabhängigen Größe beeinflußte Steuerspannung zugeführt wird. Hierdurch kann man jeder betrieblichen Forderung Rechnung tragen.It is true that mechanical Regulator or switching elements, e.g. B. use polarized relays. however one will mechanical relays when operating static converters with grid-controlled discharge vessels Avoid as much as possible, as the mechanical inertia makes operational management difficult. If possible, one becomes purely electrical, that is, arrangements that work without inertia and 'can then, so to speak, grasp operational processes as they arise. According to the invention, this can be achieved by inserting into the connection between the discharge circuits and the lattice circles controlled discharge vessels with a clear current flow direction are inserted such that the grid circles one of the sign of the current-dependent Size influenced control voltage is supplied. This allows everyone to be operational Take into account the requirement.

Es sei noch erwähnt, daß bereits eine Gleichrichteranlag .e bekannt ist, bei der die Primärwicklung des Stromwandlers in den Primärkreis des Gleichrichtertransformators geschaltet ist und die Sekundärwicklung über Hilfsentladungsgefäße in Gleichrichterschaltung eine dem Belastungsstrom proportionale Gleichspannung liefert. Es ist ferner vorgeschlagen worden, in die Verbindung zwischen den Entladungsstromkreisen und den Gitterkreisen urigesteuerte Entladungsgefäße mit eindeutiger Stromdurchlaßrichtung einzufügen. Beispielsweise kann man damit einen im Gitterkreis liegenden Kondensator mittels des Anodenstromes aufladen.It should also be mentioned that a rectifier system is already known where the primary winding of the current transformer is in the primary circuit of the rectifier transformer is switched and the secondary winding via auxiliary discharge vessels in a rectifier circuit one proportional to the load current DC voltage supplies. It has also been proposed in the connection between the discharge circuits and the lattice circles originally controlled discharge vessels with a clear current flow direction to insert. For example, you can use it to create a capacitor located in the grid circle charge by means of the anode current.

Die Verwendung von gittergesteuerten Entladungsgefäßen gemäß der Erfindung bietet gegenüber den ungestetterten Entladungsgefäßen den Vorteil, daß man den Bereich der stromabhängigen Steuerung genauer und einfacher begrenzen kaim.The use of grid-controlled discharge vessels according to the invention offers the advantage over non-esterified discharge vessels that the area the current-dependent control more precisely and easily limit kaim.
