Description

Gerät zum Kurzsohliessen des Sekundärkreises eines StromwandlerDevice for short soling the secondary circuit of a current transformer

Beim Ausschalten von elektrischen Apparaten, die direkt an einem Stromwandler angeschlossen sind, "besteht die Gefahr, dass der Sekundärkreis des Stromwandlers unbeabsichtigt geöffnet wird. Dies gilt besonders bei Verwendung einsteckbarer Apparate, z.B. Relais mit Steckerstiften. Normalerweise sind von Hand zu betätigende Umschalter mit unterbrechungsfreien Kontakten.zum Kurzschliessen des Sekundärkreises des Stromwandlers vorgesehen, die betätigt werden müssen, ehe der Apparat von seiner Montageplatte waggenommen wird. Da der Umschalter von Hand betätigt wird, besteht aber immer die Gefahr, dass eine Unterbrechung des Sekundärkreises und eine Beschädigung des Stromwandlers eintreten kann.When switching off electrical devices that are directly on connected to a current transformer, "there is a risk that the secondary circuit of the current transformer will be unintentionally is opened. This is particularly true when using plug-in devices, e.g. relays with connector pins. Normally are manually operated changeover switches with interruption-free Contacts for short-circuiting the secondary circuit of the current transformer, which must be actuated before the apparatus is dared to be removed from its mounting plate. Since the switch is operated by hand, there is always the risk of an interruption of the secondary circuit and damage to the current transformer.

Mit einem erfindungsgemässen Gerät wird automatisch ein Kurzschliessen des Sekundärkreises beim Entfernen des Apparats erhalten. Das Kurzschliessen erfolgt vor dem Herausnehmen des Apparats aus dem Sekundärkreis, so dass Jede Gefährdung des Stromwandlers ausgeschlossen ist.With a device according to the invention, the secondary circuit is automatically short-circuited when the device is removed obtain. The short circuit takes place before the device is removed from the secondary circuit, so that each Danger to the current transformer is excluded.

Das wesentliche Kennzeichen der Erfindung ist, dass die Steckvorrichtung aus einem Isolierstoffsockel mit hierin "befestigten Hülsenkontakten zur Aufnahme der Steckerstifte des in den Sekundärkreis des Stromwandlers einzuschaltenden Gerätes besteht und weiter aus einem in einem Hohlraum des Isolierst of fsockels entgegen einer Feder zwischen zwei Stellungen -verschiebbaren Kontaktbügel, der in einer Stellung die Hülsenkontakte elektrisch miteinander verbindet und durch einen am einzusteckenden Gerät befestigten Stift in eine zweite Endstellung gebracht werden kann, in der er die Hülsenkontakte nicht mehr miteinander verbindet.The main feature of the invention is that the connector from an insulated base with "attached" herein Sleeve contacts for receiving the connector pins in the secondary circuit The device to be switched on consists of the current transformer and a socket in a cavity of the insulating base against a spring between two positions -shiftable contact bracket, which in one position the sleeve contacts electrically connects with each other and brought into a second end position by a pin attached to the device to be inserted can be in which he no longer connects the sleeve contacts with each other.

Der genannte Kontaktbügel besteht aus einem dachförmig gebogenen Blechstreifen mit hakenförmig gebogenen Enden,- die durch die auf den Kontaktbügel wirkende Feder gegen die Kontakthülsen und gegen Flächen eines Steges gedruckt werden, der die den Kontaktbügel aufnehmende Öffnung des Sockels nach unten zu abschliesst. Am Kontaktbügel ist weiter ein Führungs- und Betätigungsstift von solcher Länge angebracht, dass die Verbindung der beiden Hülsenkontakte erst aufgehoben wird, nachdem die Steckerstifte des Gerätes in die Hülsenkontakte eingeführt sind.The mentioned contact bracket consists of a roof-shaped bent sheet metal strip with hook-shaped bent ends, - through the on the contact clip acting spring against the contact sleeves and against surfaces of a web are printed, which the Contact clip receiving opening of the base closes down. There is also a guide and actuation pin on the contact bracket attached of such a length that the connection of the two sleeve contacts is only canceled after the The connector pins of the device are inserted into the sleeve contacts.

Eine Aus führungs form der Erfindung in Anwendung auf ein Relais des Einstecktyps ist im folgenden anhand der Zeichnung beschrieben. One embodiment of the invention as applied to a plug-in type relay is described below with reference to the drawing.

In der Zeichnung zeigt Pig. 1 eine Montageplatte 1. Diese Platte hat runde Ausnehmungen 23, die nach der Rückseite der Platte offen und auf der Vorderseite abgesehen von den Öffnungen 24 und 25 verschlossen sind. In der Ausnehmung 23 sitzt ein runder Sockel 2 aus Isolierstoff mit einem Kragen 26, der zur Befestigung des Sockels dient. Der Sockel hat zwei durchgehende Bohrungen 11. Hierin befestigt sind zwei Hülsenkontakte 9» die zur Aufnahme der Steckers.t.ifte 21 des mit 20 bezeichneten Gerätes, z.B. eines Relais, dienen, von dem nur die Bodenplatte im Schnitt dargestellt ist.In the drawing shows Pig. 1 a mounting plate 1. This plate has round recesses 23 that face the rear the plate are open and closed on the front apart from the openings 24 and 25. In the recess 23 sits a round base 2 made of insulating material with a collar 26, which is used to attach the base. The base has two through bores 11. Two sleeve contacts 9 »for receiving the connector pins 21 are fastened here of the device marked 20, e.g. a relay, of which only the base plate is shown in section.

Der Sockel 2 hat eine trichterförmige Ausnehmung 3 von rechteckigem Grundriss, die an ihrer Spitze in eine Kammer 3a übergeht. In der Ausnehmung 3 sitzt ein dachförmig gebogener Kontaktbügel 4, dessen Steg mit 5 bezeichnet ist. Die Enden 8 des Kontaktbügels sind halbkreisförmig gebogen und stützen sich auf einem Steg 27 ab, der im Sockel 2 befestigt ist. Die Abstützflächen am Steg sind mit 10 bezeichnet. Auf den Steg 5 wirkt eine Feder 6 ein, deren anderes Ende sich am Boden der Kammer 3a abstützt. Diese Feder presst die Kontaktenden 8 gegen die Kontakthülsen 11, d.h. die Feder 4 schliesst die beiden Hülsenkontakte 11 kurz. Mit den Enden 12 dieser Hülsenkontakte sind Leitungen 13 verlötet, die zu den Sekundärklemmen des Stromwandlers führen.The base 2 has a funnel-shaped recess 3 of rectangular Floor plan that merges into a chamber 3a at its top. In the recess 3 sits a roof-shaped curved Contact bracket 4, the web of which is denoted by 5. The ends 8 of the contact clip are bent in a semicircle and support on a web 27 which is fastened in the base 2. The support surfaces on the web are denoted by 10. On the A spring 6 acts on the web 5, the other end of which is supported on the bottom of the chamber 3a. This spring presses the contact ends 8 against the contact sleeves 11, i.e. the spring 4 short-circuits the two sleeve contacts 11. With the ends 12 of these Sleeve contacts are soldered lines 13 to the secondary terminals of the current transformer.

Am Steg, 5 des Kontaktes 4 ist ein Stift 14 befestigt. Er ragt in eine Öffnung 28 des Steges 27, die gleiclifehsig mit der Öffnung 25 ist. Am Boden des Gerätes 20 ist ein Stift 22A pin 14 is attached to the web 5 of the contact 4. He protrudes into an opening 28 of the web 27, the same with the Opening 25 is. At the bottom of the device 20 is a pin 22

Dabei wird der Kontakt 4 in die Ausnehmung 3 hineingeschoben, die Kontakt enden 8 trennen sich dabei von den Hülsenkontakten 11, d.h. der Kurzschluss der Leitungen 13 wird aufgehoben. Umgekehrt wird beim Herausziehen der Steckerstifte 21 der Kurzschluss beider Leitungen wieder hergestellt, bevor die Stifte 21 die Hülsenkontakte 9 verlassen, d.h. die Sekundärwicklung des Stromwandlers ist ständig kurzgeschlossen, sei es durch den Kontakt 4 oder durch das Gerät 20 selbst.attached, which moves the pin 14 against the spring force 6 when the sockets 21 are inserted. Thereby the contact 4 pushed into the recess 3, the contact ends 8 separate from the sleeve contacts 11, i.e. the short circuit of the Lines 13 is canceled. It is reversed when pulling out the connector pins 21 the short circuit of both lines is restored before the pins 21 leave the sleeve contacts 9, i.e. the secondary winding of the current transformer is constantly short-circuited, be it through contact 4 or through the device 20 yourself.
