Schaltfelder für gekapselte Mittelspannungs-Schaltanlagen mit Schaltwagen werden herkömmlich aus vormontierten Schaltfeldgerüsten und Schaltwagen zusammengesetzt. Die Gerüste werden dabei auf der Montagefläche aus einer Reihe von platten- oder profilförmigen Teilen zu einem Kubus zusammengebaut und anschließend mit den fest eingebauten Betriebsmitteln bestückt. Die Erfindung schlägt ein Verfahren zur Montage und Bestückung der Schaltfelder vor, das die Montagezeiten verkürzt, die technische Ausführung der Schaltfelder verbessert und die Flexibilität der Auftragsbearbeitung und -abwicklung erhöht. In einer Vorfertigung werden zwei Baugruppen pro Schaltfeld als Module hergestellt, die am Montageplatz nur noch mit Hilfe von passenden Verbindungsteilen zusammengeführt werden müssen. Die eine Baugruppe besteht dabei aus einer formsteifen, wannenförmigen Rückwand, in die alle fest eingebauten Betriebsmittel unter Verwendung von Montagelehren eingebaut werden. Die andere Baugruppe beinhaltet den Frontrahmen und die Bodengruppe als Schweißkonstruktion. Die einzelnen Baugruppen und die Verbindungsteile sind erfindungsgemäß so ausgebildet, daß die den Berührungsschutz und die Personensicherheit beeinflußenden Merkmale ebenfalls verbessert sind.

Offenbart wird eine elektrische Schaltzelle, bei der eine Zellentür (1) am Rücken einen Schieber (6) trägt, der mit einem Betätigungsbolzen (7) verschiebbar ist sowie eine Durchgangsausnehmung (1o) aufweist. Der Schieber (6) ist abhängig von der Schaltstellung eines Erdungsschalters gegen eine Federkraft (9) so verschiebbar, daß die Durchgangsausnehmung (1o) mit einer ersten Ausnehmung (2) der Zellentür (1) fluchtet, wobei ein Fahrhebel auf eine Welle (3) eines Schalterwagens aufsteckbar ist. Eine Falle (11) an der Zellentür (1) sperrt in der Betriebsstellung des Schalterwagens eine zweite Ausnehmung (4) der Zellentür (1), womit eine Schaltachse (5) des Erdungsschalters unzugängig ist. Mit einem Ausheber (16) am Schalterwagen ist die Falle (11) derart schwenkbar, daß sie in der Trennstellung des Schalterwagens die zweite Ausnehmung (4) freigibt. Mit der Schaltachse (5) ist ein Schiebeglied (15) betätigbar, das im Weg des Schiebers (6) liegt, wenn der Erdungsschalter eingeschaltet und das außerhalb des Weges des Schiebers (6) liegt, wenn der Erdungsschalter ausgeschaltet ist.

There is provided an interlock apparatus of a vacuum circuit breaker for adjusting withdrawal of a circuit breaker main body, which is installed in a truck and moves to a connected position in which the circuit breaker main body is connected to a cradle and moves to a disconnected position in which the circuit breaker main body is separated from the cradle within the cradle, to outside of the cradle, which includes: a lift (100) including a rotation adjusting plate (110) provided on an upper portion thereof, and moving forwardly and backwardly such that the rotation adjusting plate is inserted into the interior of the cradle or separated from the cradle; and an interlock plate (500) provided within the cradle and rotating according to movement of the rotation adjusting plate so as to be tightly attached to the truck or released from the tightly attached state to thereby adjust withdrawal of the circuit breaker main body to the outside of the cradle.
摘要:
The invention relates to a circuit breaker system, especially an air-insulated medium voltage switchgear, with the functional features 'connect', 'disconnect' and 'earth'. The inventive circuit breaker contains a switching module (SM) which consists of function-orientated modular units, i.e. a base unit (BM), a pole unit (PM) and a drive unit (AM). The base unit (BM) is permanently connected to the drive unit (AM) and the pole unit (PM) is located on the same, in such a way that it can move in a straight line. Circuit breaker systems of this type can be used for supplying and distributing energy, especially in installations which use medium voltage technology.

A metalclad switchgear has three assemblies which are separately arranged in separate housings (48, 72, 78) for housing a circuit breaker (12), a control line (71) and a cable (34), all constituting the metalclad switchgear and which can be detachably coupled. The three assemblies are a circuit interrupting device (50), which can be designed for standardization, and a control line compartment (70) and a cable compartment (76) both of which can be designed in accordance with given specifications.
