Abstract
Description
Glühlampen sind im kalten Zustand sehr niederohmig, so daß beim Einschalten ein Stromstoß entsteht, der durch Erwärmung des Glühdrahtes und der damit verbundenen Erhöhung des Widerstandes abgebaut wird. Wird die Lampe im Maximum der Sinusspannung des Netzes eingeschaltet, so wird die Glühlampe durch einen besonders starken Stromstoß belastet. Die marktüblichen Glühlampen halten nur eine sehr begrenzte Anzahl von derartigen Stromstößen aus. Gelingt es, daß die Glühlampen nur noch im Null-Durchgang der Netzspannung eingeschaltet werden, so wird die Lebensdauer der Lampe um ein Vielfaches erhöht, da die hohen Stromstöße der Versorgungsspannung vermieden werden.Incandescent lamps are very low-resistance when cold, so that when switched on Current surge arises from the heating of the filament and thus associated increase in resistance is reduced. If the lamp in Maximum of the sinusoidal voltage of the network is switched on, so the light bulb burdened by a particularly strong current surge. The standard light bulbs can withstand only a very limited number of such surges. Succeeds, that the light bulbs are only switched on in the zero crossing of the mains voltage the lifespan of the lamp is increased many times because the high Surges in the supply voltage can be avoided.
Beim Betrieb von Glühlampen wird in Kauf genommen, daß im Spannungsmaximum oder nahe des Spannungsmaximums ein starker Stromstoß auftritt. Dies führt, speziell beim Einschalten, zu Ausfällen. Die Glühlampe muß ausgetauscht werden. When operating incandescent lamps it is accepted that the voltage maximum or a strong surge occurs near the maximum voltage. This leads to, especially when switching on, to failures. The light bulb needs to be replaced.
Der Stromstoß wird dadurch vermieden, daß eine zweipolige Vorrichtung zur Glühlampe in Serie geschaltet wird. Die Vorrichtung hat folgende Eigenschaften:The current surge is avoided in that a two-pole device for Incandescent lamp is connected in series. The device has the following properties:
A:
Sie wird niederohmig leitend, wenn die Spannung von einem Wert nahe 0 V
langsam, d. h. mit der Steilheit der Netzspannung (z. B. 50 Hz, 230 V) ansteigt.
Die Vorrichtung leitet dagegen nicht, wenn eine höhere Spannung sprungartig
angelegt wird, wie dies z. B. beim Einschalten der Glühlampe zu einem Zeitpunkt
geschieht, wenn die Spannung bereits über 10 V liegt.A:
It becomes low-resistance when the voltage rises slowly from a value close to 0 V, ie with the steepness of the mains voltage (e.g. 50 Hz, 230 V). The device, on the other hand, does not conduct when a higher voltage is applied abruptly, as z. B. happens when the light bulb is switched on at a time when the voltage is already above 10 V.
B:
Die Vorrichtung arbeitet symmetrisch, so daß die unter A: beschriebene Eigenschaft
sowohl bei positiven wie auch bei negativen Spannungen hat.B:
The device works symmetrically, so that the property described under A: has both positive and negative voltages.
C:
Die Vorrichtung kann, aber muß nicht in heißem d. h. Betriebszustand in beiden
Richtungen ständig leitend sein.C:
The device can, but does not have to be continuously conductive in both directions in the hot operating state.
Die Vorrichtung besteht aus einem Zweirichtungs-Halbleiterschalter hoher Sperrspannung, der mit Schutzschaltung ausgestattet ist, damit sie bei hoher Spannungssteilheit (du/dt) nicht zündet. Die Vorrichtung wird nur leitend, wenn eine niedrige Spannung angelegt wird, die langsam ansteigt wie dies z. B. bei der Netzspannung in Nähe des Null-Durchganges der Fall ist.The device consists of a bi-directional high semiconductor switch Reverse voltage, which is equipped with protective circuit so that it at high Slope of tension (du / dt) does not ignite. The device only becomes conductive if one low voltage is applied, which slowly rises like this e.g. B. at the Mains voltage near the zero crossing is the case.
Die Vorrichtung kann für kleinere Leistungen als Einzelbauelement eingesetzt werden.The device can be used as an individual component for smaller outputs become.
Größere Leistungen können geschaltet werden, wenn die Vorrichtung als Treiber leistungsstärkerer Thyristoren oder Triacs verwendet wird wie das in Bild 3/4 dargestellt ist.Larger powers can be switched if the device is used as a driver more powerful thyristors or triacs are used like the one in Fig. 3/4 is shown.
Die Vorrichtung kann in die Lampenfassung eingebaut sein, in den Schalter oder an einer beliebigen anderen Stelle in der Leitung.The device can be installed in the lamp holder, in the switch or on anywhere else on the line.
Sie kann aus mehreren einzelnen Bauelementen bestehen oder aus einem monolithisch integierten Halbleiter. Das Prinzip der Schaltungen ist in den Bildern 1-4 dargestellt.It can consist of several individual components or one monolithically integrated semiconductor. The principle of the circuits is in the pictures 1-4 shown.
