störanfällig. Die im ersteren Falle benötigten Schaugläser bzw. Sichtfenster in der Kapselung sind aus mehreren Gründen (Druckfestigkeit, Verschmutzung usw.) unerwünscht. Schliesslich ist es aus der CH-PS 462 925 an sich bekannt, bei gekapselten Hochspannungsschaltanlagen zur Erfassung des Spannungszustandes von Leiterteilen einen kapazitiven Spannungsteiler vorzusehen, wobei letzterer an einem drei feste Gegenkontakte enthaltenden Teil von drei Trennern angeschlossen ist.prone to failure. The inspection glasses or inspection windows required in the first case in the enclosure are for several reasons (pressure resistance, Pollution, etc.) undesirable. Finally, it is known per se from CH-PS 462 925 for encapsulated high-voltage switchgear to provide a capacitive voltage divider to detect the voltage state of conductor parts, the latter is connected to a part of three isolators containing three fixed mating contacts.

Der Erfindung liegt die Aufgabe zu Grunde, bei gekapselten Hochspannungsschaltanlagen der eingangs erwähnten Art eine einfache und billige Lösung zur Erkennung des freigeschalteten Zustandes eines abtrennbaren Anlageteiles im Inneren der Kapselung anzugeben. Erfindungsgemäss wird vorgeschlagen, dass gegenüber von dem zu erdenden Anlageteil eine Messelektrode nahe der Kapselung gegen letztere isoliert angeordnet ist und die Messelektrode mit dem Messanschluss des Spannungsteilers verbunden ist.The invention is based on the object of encapsulated high-voltage switchgear of the type mentioned at the beginning, a simple and cheap solution for recognizing the activated state of a separable system part inside the enclosure. According to the invention it is proposed that compared to the to grounding part of the system a measuring electrode is arranged near the encapsulation insulated from the latter and the measuring electrode with the Measurement connection of the voltage divider is connected.

ehe mittels der Isolatoren 4 zentrisch in der Kapselung 1 gehaltert sind. Im Leitungsteil 2 ist das bewegliche Trennerschaltstück 5 gleitend gelagert, welches mittels seiner Betätigungsstange 5a durch einen nicht näher dargestellten Antrieb bekannter Art ein- bzw. ausgeschaltet werden kann. Die Stromübertragung vom Schaltstück 5 zum Leiterteil 2 erfolgt mittels des ringförmigen Gleitkontaktes 5b. In der gezeichneten Lage befindet sich das Schaltstück 5 in Stellung "Aus". Das Leiterteil 5 trägt stirnseitig das ringförmige Gegenkontaktstück 6 für das Trennerschaltstück 5 und das Gegenschaltstück 8 für den Schaltstift 9 der Erdungsschalters. Letzterer ist als Handerder ausgebildet und befindet sich in dem an die Kapselung 1 angeflanschten Gehäuse 10. Der Schaltstift 9 des Erdungsschalters ist von der ringförmigen Messelektrode 11 berührungslos umgeben, wobei letztere durch die Isolierscheibe 12 gegenüber der Kapselung 1 bzw. dem Gehäuse 10 isoliert befestigt ist. Die Messelektrode 11 ist an die Messleitung 13 angeschlossen, welche isoliert aus der Kapselung 1 zum Messanschluss l4 herausgeführt ist. An den Messanschluss 14 kann ein z.B. tragbares Spannungsmessgerät mit hochohmigem Eingang angeschlossen werden. Durch diese isolierte Anordnung der Messelektrode 11 wird ein kapazitiver Spannungsteiler gebildet, dessen Teilkapazitäten einerseits durch die natürlichen Kapazitäten zwischen den Teilen 2, 3 und der Messelektrode 11 und andererseits von derjenigen zwischen letzterer und der Kapselung 1 gebildet werden. Je nachdem, in welcher Lage sich das Trennerschaltstück 5 befindet, wird durch das an den Messanschluss l4 angeschlossenebefore held centrally in the encapsulation 1 by means of the insulators 4 are. In the line part 2, the movable disconnector 5 is slidably mounted, which by means of its actuating rod 5a a known type not shown drive can be switched on or off. The power transmission from the contact piece 5 to Conductor part 2 takes place by means of the annular sliding contact 5b. In the position shown, the contact piece 5 is in position "The end". The front side of the conductor part 5 carries the annular mating contact piece 6 for the disconnector 5 and the counter contact 8 for the switching pin 9 of the earthing switch. The latter is as Hand earth formed and is located in the housing 10 flanged to the encapsulation 1. The switching pin 9 of the earthing switch is surrounded in a contactless manner by the ring-shaped measuring electrode 11, the latter being protected by the insulating disk 12 opposite the encapsulation 1 or the housing 10 is secured in an isolated manner. The measuring electrode 11 is connected to the measuring line 13, which is isolated from the Encapsulation 1 is led out to the measuring connection l4. A portable voltage measuring device, for example with a high-resistance voltage, can be connected to the measuring connection 14 Input can be connected. This isolated arrangement of the measuring electrode 11 forms a capacitive voltage divider, its partial capacities on the one hand by the natural capacities between the parts 2, 3 and the measuring electrode 11 and on the other hand are formed by that between the latter and the encapsulation 1. Depending on the position in which the disconnector 5 is, is connected to the measuring connection l4

Spannungsmessgerät ein hoher (Stellung "Ein") oder ein sehr viel geringerer (Stellung "Aus") Spannungswert angezeigt. Letzterer kann auch als Kontrolle für das Spannungsmessgerät herangezogen werden, sofern es nicht einen eigenen Prüfkreis besitzt. Der Messanschluss kann so ausgebildet sein, dass er bei nicht angeschlossenem Spannungsmessgerät mit der Kapselung verbunden ist.Voltmeter shows a high ("On" position) or a much lower ("Off" position) voltage value. The latter can can also be used as a control for the voltage measuring device, provided it does not have its own test circuit. The measuring connection can be designed so that it is connected to the encapsulation when the voltage measuring device is not connected.
