Prüfstecker zum Prüfen des Schutzleiters in elektrischen SteckdosennetzenTest plug for testing the protective conductor in electrical socket networks
In den Bedienungsanleitungen und Anschlußvorschriften zu elektrischen Geräten der Schutzklasse 1 wird ausdrücklich gefordert, vor dem Anschluß des jeweiligen Gerätes zu prüfen, ob der Schutzleiter des Steckdosennetzes funktionstüchtig ist. Die Betreiber von elektrischen Haushaltsgeräten oder dergleichen, verfügen jedoch selten über die erforderlichen Kenntnisse und technischen Mittel, die zum ordnungsgemäßen Prüfen der Funktionstüchtigkeit eines Schutzleiters notwendig sind. Andererseits weisen bekannte Prüfvorrichtungen sehr aufwendige elektronische Schaltungen auf und erfordern eine gewisse Fachkenntnis, so daß sie für den Gebrauch durch Nichtfachleute ungeeignet sind.The operating instructions and connection regulations for electrical devices in protection class 1 expressly require that you check whether the protective conductor of the socket is functioning properly before connecting the device. However, operators of electrical household appliances or similar rarely have the necessary knowledge and technical means to properly check whether a protective conductor is functioning properly. On the other hand, known test devices have very complex electronic circuits and require a certain level of specialist knowledge, so that they are unsuitable for use by non-specialists.
Es ist daher Aufgabe der Erfindung, ein Gerät zum Prüfen des Schutzleiters in elektrischen Steckdosennetzen zu schaffen, welches äußerst kostengünstig herstellbar und einfach zu handhaben ist.It is therefore an object of the invention to provide a device for testing the protective conductor in electrical socket networks, which is extremely cost-effective to manufacture and easy to handle.
Die Aufgabe wird durch einen Prüfstecker mit den im Schutzanspruch 1 angegebenen Merkmalen gelöst.The object is achieved by a test plug with the features specified in claim 1.
Die Vorteile der Erfindung bestehen insbesondere darin, daß der Prüfstecker aus einem handelsüblichen Zwischenstecker mit äußerst geringem Schaltungsaufwand besteht. Durch die Ausbildung als Zwischenstecker kann der Prüfstecker auch zur ständigen Überwachung der Funktionstüchtigkeit des Schutzleiters verwendet werden, wobei an der selben Netzsteckdose gleichzeitig ein elektrisches Gerät betrieben werden kann. Die optische Zuordnung der Glimmlampen zum jeweiligen Steckbuchsenkontakt der Netzsteckdose gemäß Schutzanspruch 2 ermöglicht außerdem auf einfache Weise das Ermitteln der Lage des Außenleiters in einer Netzsteckdose. Durch eine gut sichtbare undThe advantages of the invention are in particular that the test plug consists of a commercially available adapter plug with extremely low circuit complexity. Due to the design as an adapter plug, the test plug can also be used for the constant monitoring of the functionality of the protective conductor, whereby an electrical device can be operated at the same time on the same mains socket. The optical assignment of the glow lamps to the respective socket contact of the mains socket according to protection claim 2 also enables the position of the outer conductor in a mains socket to be determined in a simple manner. A clearly visible and
abstrahlende Anordnung der Glimmlampen kann der erfindungsgemäß ausgestaltete Prüfstecker auch als sogenanntes energiesparendes Nachtlicht verwendet werden.Due to the radiating arrangement of the glow lamps, the test plug designed according to the invention can also be used as a so-called energy-saving night light.
Ein Ausführungsbeispiel der Erfindung wird anhand der Figur und am Beispiel eines einphasigen Wechselstromnetzes näher erläutert.An embodiment of the invention is explained in more detail using the figure and the example of a single-phase alternating current network.
In einem nicht dargestelltem, bekannten Zwischenstecker mit Kontaktstiften und Kontaktbuchsen für den Außenleiter L und den Neutralleiter N sowie einem Schutzkontakt PE sind die Kontakte für den Außenleiter L und den Neutralleiter N jeweils über eine mit einem Widerstand Rl bzw. R2 in Reihe geschaltete Glimmlampe Gl bzw. G2 mit dem Kontakt für den Schutzleiter PE verbunden. Die Glimmlampen Gl und G2 sind gut sichtbar im Gehäuse des Zwischensteckers angeordnet. Dabei sind die Glimmlampen Gl und G2 jeweils dem Steckdosenkontakt optisch zugeordnet, in dessen Verbindungsleitung zum Schutzleiter PE sie angeordnet sind.In a known adapter plug (not shown) with contact pins and contact sockets for the outer conductor L and the neutral conductor N as well as a protective contact PE, the contacts for the outer conductor L and the neutral conductor N are each connected to the contact for the protective conductor PE via a glow lamp Gl or G2 connected in series with a resistor Rl or R2. The glow lamps Gl and G2 are arranged in a clearly visible manner in the housing of the adapter plug. The glow lamps Gl and G2 are each optically assigned to the socket contact in whose connecting line to the protective conductor PE they are arranged.
Ist der Prüfstecker in eine Netzsteckdose eingesteckt und der Schutzleiter PE des Steckdosennetzes ist funktionstüchtig, fließt über den Widerstand Rl und die Glimmlampe Gl oder, bei um 180° gedrehter Einstecklage des PrüfSteckers, über den Widerstand R2 und die Glimmlampe G2 zwischen dem Außenleiter L und dem Schutzleiter PE ein Strom, wodurch die Glimmlampe Gl oder G2 leuchtet. Das Leuchten nur einer Glimmlampe ist die Anzeige für die Funktionstüchtigkeit des Schutzleiters PE. Es leuchtet jeweils die Glimmlampe, die dem Steckdosenkontakt optisch zugeordnet ist, an dem der Außenleiter L anliegt. If the test plug is plugged into a mains socket and the PE protective conductor of the socket network is functioning, a current flows via the resistor Rl and the glow lamp Gl or, if the test plug is turned by 180°, via the resistor R2 and the glow lamp G2 between the outer conductor L and the PE protective conductor, causing the glow lamp Gl or G2 to light up. The lighting of only one glow lamp indicates that the PE protective conductor is functioning. The glow lamp that is optically assigned to the socket contact to which the outer conductor L is connected lights up.
Ist der Schutzleiter PE im Steckdosennetz unterbrochen, kommt es über Rl, Gl, G2 und R2 zu einem Stromfluß zwischen dem Außenleiter L und dem Neutralleiter N, wodurch beide Glimmlam-If the protective conductor PE in the socket network is interrupted, a current flows between the outer conductor L and the neutral conductor N via Rl, Gl, G2 and R2, causing both glow lamps
pen Gl und G2 leuchten und damit den Defekt des Schutzleiters PE anzeigen.pens Gl and G2 light up, indicating a defect in the protective conductor PE.
Die Erfindung ist auch in Ausgestaltungen für mehrphasige Steckdosennetze realisierbar.The invention can also be implemented in designs for multi-phase socket networks.
