Description
Während die Notbeleuchtungen älterer Art im allgemeinen so eingerichtet waren, daß der zur Speisung der Notlampe dienende Akku-. nullator zum Zweck · der Neuaufladung aus" der Einrichtung herausgenommen werden mußte, geschieht die Ladung mittels vorliegender neuer Schaltung im Apparat selbst-' tätig. ■ ■·■ While the older type of emergency lights were generally set up so that the battery used to power the emergency lamp. nullator had to be removed from the device for the purpose of recharging, the charging takes place automatically by means of the new circuit in the device . ■ ■ · ■
Das Wesentliche der neuen Erfindung ist ίο die Benutzung eines gemeinsamen Leiterstückes für zwei Stromkreise verschiedener . Stromquellen, also beispielsweise zweier voneinander unabhängiger Gleichstromerzeuger oder eines Gleichstrom- und eines Wechsel-Stromerzeugers, zu dem Zweck, jede Störung des einen Stromkreises durch sichtbare oder hörbare oder beiderlei Zeichen im andern Stromkreise bemerkbar zu machen.The essence of the new invention is ίο the use of a shared ladder section for two different circuits. Power sources, for example two independent direct current generators or a direct current and an alternating current generator, for the purpose of eliminating any disturbance one circuit through visible or audible or both signs in the other To make circuits noticeable.
Die zum Relais R gehörige Spule ist in Reihe geschaltet mit dem Akkumulator A und der Notlampe NL, und dieser Stromkreis bildet gewissermaßen den Primärstromkreis. Die Spule R wirkt hierbei als Vorschaltwiderstand für den Akkumulator. Ist der Widerstand dieser Spule sehr hoch, so daß die Ladcstromstärke nicht genügend groß wird, so kann parallel zur Spule die Hauptlampe HL, gewöhnlich eine iokerzige Metallfaden-• lampe, geschaltet werden. Die Ladestromstärke wird in den meisten Fällen etwa ein bis mehrere Zehntel Ampere betragen. Da die Notlampe NL etwa 1 Ampere Strom benötigt, bleibt sie während der Ladung dunkel. Der Anker des Relais ist, solange die Hauptleitung unter Spannung steht, angezo-. gen, und der Sekundärstromkreis, gebildet durch den Akkumulator A, die Notlampe NL und den Relaisanker, ist offen. Wird die Hauptleitung aus irgendeinem Grunde spannungslos, so fällt der Anker herab, über- brückt die Leitung, und die Notlampe leüch-. tet auf. Die Eiitladeströmstärke des Akkumulators über den Primärstromkreis ist infolge der hohen Widerstände der Hauptlampe und des Relais gering und beträgt nur *·> einige Milliampere. . ,The coil belonging to the relay R is connected in series with the accumulator A and the emergency lamp NL, and this circuit forms, so to speak, the primary circuit. The coil R acts as a series resistor for the accumulator. If the resistance of this coil is very high, so that the charging current is not sufficiently high, the main lamp HL, usually a square metal filament lamp, can be switched in parallel to the coil. In most cases, the charging current will be around one to several tenths of an ampere. Since the emergency lamp NL requires around 1 ampere current, it remains dark during charging. The armature of the relay is tightened as long as the main line is live. gen, and the secondary circuit, formed by the accumulator A, the emergency lamp NL and the relay armature, is open. If the main line is de-energized for any reason, the anchor drops, bridges the line and the emergency lamp lights up. opens. The charging current of the accumulator via the primary circuit is low due to the high resistances of the main lamp and the relay and is only *> a few milliamperes. . ,
Hat die Relaisspule verhältnismäßig niedrigen Widerstand, so daß der Strom, der durch die Spule fließt, zur Akkumulatorenladung1 ausreicht, so kann die-,Hauptlampe auch parallel zum Netz gelegt werden, wobei · jedoch ein A^orteil der dargestellten Schaltung verlorengeht.If the relay coil has a relatively low resistance, so that the current flowing through the coil is sufficient to charge the battery 1 , the main lamp can also be connected in parallel to the mains, although an advantage of the circuit shown is lost.
Bei dieser Schaltung, bei der also die Hauptlampe HL parallel zur Spule R liegt, s5 wird nämlich, falls während der Zeit, in der die Hauptleitung unter Spannung steht und der Akkumulator geladen wird, also auch die Hauptlampe brennt, am Akkumulator oder an der Notlampe eine Störung eintritt (sei es durch Bruch der Leitung oder schlechten Kontakt am Akkumulator oder durch Beschädigung des Glühfadens), der Primärstromkreis unterbrochen. Der Netzstrom fließt alsdann nur über die Relaisspule sowie die dazu parallellicgende Hauptlampe und über den Anker zum Netz zurück.In this circuit, in which the main lamp HL is parallel to the coil R , s5 is namely, if during the time in which the main line is live and the accumulator is being charged, i.e. the main lamp is also on, on the accumulator or on the emergency lamp a fault occurs (be it due to a break in the line or poor contact on the accumulator or damage to the filament), the primary circuit is interrupted. The mains current then only flows back to the mains via the relay coil and the main lamp in parallel and via the armature.
Hierbei wirkt jedoch das Relais als Selbstunterbrecher und erzeugt ein lautes, schnarrendes Geräusch. Gleichzeitig flackert die Hauptlampe. Dies dauert so lange, bis der , Fehler im Apparat behöben ist. Durch diese 'Here, however, the relay acts as a self-interrupter and generates a loud, rasping sound Noise. At the same time the main lamp flickers. This lasts until the Has corrected the fault in the device. Through this '
