Description

Elektrischer Schalter, insbesonderE.Xleinselbstschalter, mit abnehmbarer Lichtb'ögensct@tzkappe -Die Lichtbogenkammern und Liehtbogenschutzwände, die bei @elektrisch#en- Schaltgesäten bisher angewendet wurden, bestehen im allgemeinen aus undurchsichtigem.-.keramischem Werkstoff. Allerdings. hat man auch schon durchscheinende `keramische P`radukte für die Schalterkappen von Stöps,els@elbst;-schältern verwendet: Man hat jedoch die durchscheinende Eigenschaft als nachteilig empfunden, weil unter Umständen der bei einer Abschaltung ;auftretende Lichtbogenscheüi -,ehe gewisse Beängstigung schreckhafter Personen hervorrufen könnte, und deswegen vorgeschlagen, diese Eigenschaft der Kappe durch eine Auskleidungg mittels nicht durchscheinender Stoffe oder Auftragen eines entsprechenden Überzuges unwirksam zu machen: Die Erfindung bezieht sieh auf elektrische Schalter; insbesondere Kleinselbstschalter, mit abnehmbarer Lichtbogenschutzkappe: Ihr Vorschlag- besteht -darin, die Lichtbogenschutzlkappe aus durchsichtigem Stoff herzustellen. Vorzugsweise kommt hierfür Glas von hinreichender Wäxmeb,eständigkeit ixt Betracht.Electrical switch, especially E. Xleinswitch, with removable Lichtb'ögensct @ tzkappe -The arc chambers and arc protection walls that come with @ electrical # en switching devices have been used so far, exist in general made of opaque ceramic material. However. you already have translucent ones Ceramic products are used for the switch caps of Stöps, els @ elbst; -shells: However, the translucent property has been found to be disadvantageous because it is below Circumstances that occur in the event of a shutdown; arcing protection - before certain Could cause anxiety in frightened people, and therefore suggested that this property of the cap through a lining by means of non-translucent To make substances or the application of a corresponding coating ineffective: The invention refers to electrical switches; especially small self-switch, with removable Arc protection cap: Your suggestion consists of the arc protection cap made from transparent fabric. Preferably, glass is sufficient for this Wäxmeb, durability ixt consideration.

Es sind zwar auch schön Vorschläge bekänntgeworden; Glas als: Behälter für das Löschm-editun bei Ho:chspannungsflüssigkeitsschaltern, bei Hochspannungssicherungen und bei ölschützen zu verwenden. Teilweise hat man bei Schaltern in unmittelbarer Nähe der Unterbrechungsstelle Isolierkörper aus Hartglas deswegen angeordnet, weil der @erwähnte Werkstoff gegenüber dem Lichtbogen besonders widerstandsfähig sei; auf die Ausnutzung der Durchsichtigkeit des Glases kam es dabei jedoch flicht an. Bei Hoehsp:annungss,chelt?-geräten haben Glasgefäße die im allgemeinen als störend empfundene Eigenschaft;: die außerordentlich starke Feuererscheinung des Schaltlichtbogens durchzulassen. ölgefäßeaus Glas bei Schützen ö. dgl. lassen bereits. nach' verhältnismäßig kurzer Benutzungsdauer die Kontakte von ,außen nicht' mehr genau erkennen, weil das Öl nach einer gewissen Anzahl Schaltungen bekanntlich dunkel und undurchsichtig wird.It is true that suggestions have also become known; Glass as: container for the extinguishing editun with high voltage liquid switches, with high voltage fuses and to be used by oil shooters. Sometimes you have switches in the immediate vicinity Near the point of interruption, the insulating body made of tempered glass is arranged because the @ mentioned material is particularly resistant to the electric arc; the use of the transparency of the glass was what mattered. At Hoehsp: annungss, chelt? Devices, glass vessels are generally considered to be annoying perceived property;: the extraordinarily strong fire phenomenon of the switching arc to let through. Oil vessels made of glass with Schützen or the like already leave. after 'proportionately short period of use no longer precisely recognize the contacts from the 'outside' because the oil is known to be dark and opaque after a certain number of switching operations will.

Die Erfindung bringt dagegen für elektrische Schalter mit einer abnehmbaren Lichtbogenschutzkappe, für ,deren Herstellung man bisher undurchsichtige keramische Wandungen verwandte; den Vorteil mit sich, daß die: Schaltstellen durch die Wandungen der Lichfibogenschützvorrichtung hindurch von. außen beobachtet werden. können. Dadurch wird de Nachprüfung des Zustandes der Kontakte b@eträchtlich erleichtert.The invention brings against it for electrical switches with a removable Arc protection cap, for whose manufacture was previously opaque ceramic Walls related; with the advantage that the: switching points through the walls the optical arc protection device through from. be observed outside. can. This makes checking the condition of the contacts much easier.

Die Abbildung zeigt als Ausführungsbeispiel zwei Schaltstellen eines Niederspännungs- -schaltgerätes mit aufgesetzter Lichtbogenkämmer gemäß der Erfindung. i; z sind die beiden Schaltstellen, die auf einer Grundplatte 3 angeordnet sind. ¢ ist die für beide Schaltstellen gemeinsame Lichtbogenkammer, die im Innern durch ,eine Zwischenwandung 5 in zwei Räume für die beiden Schaltstellen unterteilt ist.- Die Lichtbogienkanuner kann ' als' Preßteil hergestellt sein Der Vorteil der Sichtbarkeit der Schaltstücke von mehreren Seiten her bei aufgesetzten Lichtbogenschutzvorrichtung ist nament lich für den Bau kleiner elektrischer Scl:Jnenschalter, Niederspannüngsselbstschalter und Schützen mit Überström- und gegebenenfalls auch.. mit Kurzschlußauslösung bedeutungsvoll.The figure shows two switching points of one as an exemplary embodiment Low-voltage switching device with attached arcing chamber according to the invention. i; z are the two switching points which are arranged on a base plate 3. ¢ is the arc chamber that is common to both switching points and passes through inside , an intermediate wall 5 is divided into two rooms for the two switching points. The arc tube can be manufactured 'as' a pressed part. The advantage of visibility of the contact pieces from several sides when the arc protection device is in place is especially for the construction of small electrical switches: internal switches, low-voltage self-switches and protection with overflow and possibly also .. with short-circuit release is significant.
