Die Erfindung geht aus von bekannten Schaltstellungsanzeigen und -Verriegelungen für Leistungsschalteranlagen, insbesondere für luftisolierte Mittelspannungs-Schaltanlagen, mit den Funktionsmerkmaien "Leistungsschalten", "Trennen" und "Er- den".The invention is based on known switch position indicators and interlocks for circuit breaker systems, in particular for air-insulated medium-voltage switchgear systems, with the functional characteristics "power switching", "disconnecting" and "grounding".
Leistungsschalteranlagen mit diesen Funktionsmerkmaien sind hinreichend bekannt und sind entsprechend den einschlagigen Bestimmumgen für Stellungsanzeigen der Leistungsschalter mit ihren Trenner- und Erderfunktionen nach VDE 0670 Teil 1000 sowie für Verriegelungen der sich gleichzeitig auszuschließenden Funktionen nach VDE 0670 Teil 6 (Verriegelungen/Empfehlungen) ausgelegt.Circuit breaker systems with these functional characteristics are well known and are designed in accordance with the relevant provisions for position indicators of the circuit breakers with their isolating and earthing functions in accordance with VDE 0670 Part 1000 as well as for interlocking the functions to be excluded according to VDE 0670 Part 6 (interlocks / recommendations).
Die Stellungsanzeigen der Leistungsschalteranlagen und die funktionellen Verriegelungen sind, wie beispielsweise aus der DE 44 45 081 AI ersichtlich, weitestgehend durch individuelle Hebelgestange gesteuert und dementsprechend sehr eng an die konstruktiven Gegebenheiten der unterschiedlichen Leistungsschalteranlagen angepaßt. Je nach Art und Ausbau der Leistungschalteranlagen sind somit verschiedenartigste Steu- ermechanismen mit sehr unterschiedlichen Einbauvolumen vorgesehen, deren Vielfalt mit zunehmenden Kundenwunschen entsprechend hoch ist. Neben den entsprechend notwendigen Anpassungsentwicklungen bei schon geringfügigen konstruktiven Veränderungen bestehender Leistungsschalteranlagen sind msbe- sondere für neu entwickelte Anlagenkonzepte stets auch aufwendige Neuentwicklungen m Bezug auf die Schaltstellungsanzeigen und -Verriegelungen für die Leistungsschalteranlagen notwendig. Die der Erfindung zugrunde liegende Aufgabe besteht darin, die Vielzahl der unterschiedlichen Konstruktio- nen bei den Schaltstellungsanzeigen und -Verriegelungen für die Leistungsschalteranlagen erheblich zu verringern und darüber hinaus das Einbauvolumen dieser Schaltstellungsanzeigen und -Verriegelungen merkbar zu reduzieren. Erfmdungsgemaß wird dies durch die Merkmale 1.1 die Schaltstellungsanzeigen und -Verriegelungen sind gemeinsam m Steuermodule integriert, 1.2 die Schaltstellungsanzeigen und -Verriegelungen sind durch Anzeigeschieber und Vemegelungsschieber realisiert, 1.3 die Steuermodule weisen eweils ein die Anzeigeschieber und die Vemegelungsschieber führendes Mittelblech auf, das zwischen einem frontseitigen Abdeckblech und einem dem Innenbereich der Leistungsschalteranlagen zugewandten Halteblech angeordnet ist, 1.4 das Mittelblech weist eine an die Positionen und Konturen der Anzeigeschieber und der Verriegelungsschieber angepaßte Zahl von Fuhrungsoffnungen auf,The position indicators of the circuit breaker systems and the functional interlocks are, as can be seen for example from DE 44 45 081 AI, largely controlled by individual lever linkages and accordingly very closely adapted to the structural conditions of the different circuit breaker systems. Depending on the type and configuration of the circuit breaker systems, a wide variety of control mechanisms with very different installation volumes are provided, the diversity of which is correspondingly high with increasing customer requirements. In addition to the correspondingly necessary adaptations in the case of even minor structural changes to existing circuit breaker systems, complex new developments are always necessary, especially for newly developed system concepts in relation to the switch position indicators and interlocks for the circuit breaker systems. The object on which the invention is based is to cover the large number of different constructions in the switch position indicators and locks to significantly reduce the circuit breaker systems and also to noticeably reduce the installation volume of these switch position indicators and interlocks. According to the invention, this is achieved by features 1.1, the switch position indicators and locks are jointly integrated in m control modules, 1.2 the switch position indicators and locks are implemented by indicator slides and locking slides, 1.3 the control modules sometimes have a center plate guiding the indicator slides and the locking slider, which is between a front panel Cover plate and a holding plate facing the inner region of the circuit breaker systems, 1.4 the middle plate has a number of guide openings adapted to the positions and contours of the indicator slides and the locking slides,

Mit der Integration der Schaltstellungsanzeigen und der Schaltstellungsvemegelungen m einem gemeinsamen Steuermodul sind die konstruktiven Voraussetzungen für ein einheitliches Steuerungskonzept für Leistungsschalteranlagen auch mit unterschiedlichen Leistungsmerkmalen gegeben. Die Steuermodule sind m sogenannter "sandwich" - Bauweise ausgeführt, wobei die Schaltstellungsanzeigen als Anzeigeschieber und die Schaltstellungsvemegelungen als Vemegelungsschieber realisiert sind. Die Anzeigeschieber und die Vemegelungsschie- ber sind dabei m einem Mittelblech gefuhrt, das frontseitig durch ein Abdeckblech mit entsprechenden Betrachtungscffnungen und anlagenseitig durch ein Halteblech mit entsprecnenden Durchfuhrungsoffnungen begrenzt ist. Das Steuermodul ist als kompakte Baueinheit ausgestaltet und kann als standardisierte Baugruppe unabhängig vom Leistungsumfang der Leistungsscnal- teranlagen m dieselben eingesetzt werden.With the integration of the switch position indicators and the switch position adjustments in a common control module, the design requirements for a uniform control concept for circuit breaker systems are also given with different performance features. The control modules are designed in a so-called "sandwich" construction, the switch position indicators being implemented as indicator slides and the switch position adjustments being implemented as locking slides. The indicator slides and the locking slides are guided in a middle plate on the front is limited by a cover plate with corresponding viewing openings and on the plant side by a holding plate with corresponding through openings. The control module is designed as a compact structural unit and can be used as a standardized assembly regardless of the scope of the performance switch systems.

Leistungsschaltern die Anzeigeschieber die Bewegbarkeit der Vemegelungsschieber sperren, vorgesehen.Circuit breakers, the indicator slides, block the mobility of the locking slides.
Mit der gradlinigen Fuhrung der Anzeigeschieber und der Ver- riegelungsschieber im Mittelblech ist m besonders einfacher Weise ein Sperr- und Freizustand der Verriegelungsschieber erreicht .With the straight-line guidance of the indicator slides and the locking slides in the center plate, the locking slides can be locked and released in a particularly simple manner.
Eine weitere vorteilhafte Ausgestaltung der Erfindung sieht die MerkmaleA further advantageous embodiment of the invention sees the features
3.1 den Anzeigeschiebern sind Stellungszustande der Leistungsschalter zugeordnet, 3.3 den Vemegelungsschiebern sind FunktionszulassigA-.ts- zustande von Trennern und Erdern zugeordnet, vor.3.1 The position sliders of the circuit breakers are assigned to the indicator slides, 3.3 to the locking slides are functionally permissible A-.ts- states of isolators and earthing assigned.
Mit dieser festen Zuordnung zu den verschieden Komponenten der Leistungsschalteranlagen sind erleichterte und weitestge- hend fehlerfreie Bedienungsweisen m den Schaltwarten ermöglicht.This fixed assignment to the various components of the circuit breaker systems makes it easier and enabling flawless operating methods in the control rooms.
Eine weitere vorteilhafte Ausgestaltung der Erfindung ist durch die MerkmaleA further advantageous embodiment of the invention is due to the features
4.1 die Stellungszustande der Leistungsschalter sind auf den Anzeigeschiebern durch Quer- und Langsbalken symbolisiert,4.1 the position of the circuit breakers is symbolized on the slide indicators by cross and long bars,
4.2 die Funktionszulassigkeitszustande von Trennern und Er- dern sind mittels der Vemegelungsschieber durch Sperrung bzw. Freigabe von Durchfuhrungen zu Antriebsachsen derselben realisiert, erreicht .4.2 The functional admissibility states of isolators and earth electrodes have been achieved by means of the locking slide by blocking or releasing bushings to their drive axes.
Die weitestgehend fehlerfreien Bedienungsweisen m den Schaltwarten werden durch diese Merkmale noch zusatzlich ge¬ fordert .The largely error-free operation modes m the control rooms are overwhelmed by these features yet additionally ge ¬.
Die Erfindung wird durch ein m zwei Figuren dargestelltes Ausfuhrungsbeispiel naher erläutert, wobei die Figur 1 die Stirnansicht des Steuermoduls im Schnitt darstellt und die Figur 2 die Forderansicht des Steuermoduls mit entferntem Abdeckblech zeigt.The invention is explained in more detail by an exemplary embodiment shown in two figures, FIG. 1 showing the front view of the control module in section and FIG. 2 showing the front view of the control module with the cover plate removed.
Der Figur 1, die das Steuermodul STM im Schnittbild entlang der Schnittlinie X, Y der Figur 2 zeigt, ist in besonderer Weise die "sandwich" - Bauweise des Steuermoduls STM zu entnehmen. Das Steuermodul STM weist das Mittelblech MBL auf, m deren Ausnehmungen der Anzeigeschieber AZS eines nicht darge- stellten Leistungsschalters und der Vemegelungsschieber VRS der ebenfalls nicht dargestellten Trenner und Erder gefuhrt sind. Das Mittelblech MBL ist frontseitig durch das Abdeckblech ABL und anlagenseitig durch das Halteblech HBL begrenzt. Durch den unterbrochenen Linienzug ist der Steue- rungskomponenetenbereich SKB angedeutet, m dem die zur Steu- erung der Leistungsschalter sowie der Erder und Trenner notwendigen Schaltgestange entsprechend räumlich angeordnet sind.FIG. 1, which shows the control module STM in the sectional view along the section line X, Y of FIG. 2, shows in a special way the "sandwich" design of the control module STM. The control module STM has the center plate MBL, the recesses of which are the indicator slide AZS of a circuit breaker (not shown) and the locking slide VRS of the isolators and earth electrodes, also not shown. The middle plate MBL is limited on the front by the cover plate ABL and on the system side by the holding plate HBL. The broken component line indicates the control component area SKB, in which the control component area tion of the circuit breakers and the earthing and isolating switch rods necessary are arranged spatially accordingly.
Weiterhin sind m dieser Ansicht die Fuhrungsoffnung FUO im Mittelblech MBL und die Durchfuhrungsoffnung DUO im Halteblech HBL angedeutet.Furthermore, the guide opening FUO in the middle plate MBL and the through opening DUO in the holding plate HBL are indicated in this view.
Die Figur 2 zeigt das Steuermodul STM mit nur einem Teilaus- schnitt des Abdeckbleches ABL mit der Betrachtungsoffnung BEO. Hinter dem Abdeckblech ABL befindet sich das Mittelblech MBL mit dem dahmterliegenden Halteblech HBL. Das Mittelblech MBL weist die Fuhrungsoffnung FUO auf, m der der Vemegelungsschieber VRS und der Anzeigeschieber AZS jeweils m Pfeilrichtung verschiebbar sind. Im dargestellten Zustand ist der Anzeigeschieber AZS so positioniert, daß der Vemegelungsschieber VRS m den Pfeilrichtungen verschiebbar ist. In dem Mittelblech MBL sind der Vemegelungsschieber VRS und der Anzeigeschieber AZS derart angeordnet, daß bei eingeschalteten Leistungsschaltern mit dem Verschieben der Anzei- geschieber ASZ m einfacher Weise der Sperrzustand der Ver- riegelungsschieber VRS bewirkt ist. So ist beispielsweise mit dem m der Betrachtungsoffnung BEO das Abdeckbleches ABL erkennbaren Querbalken des Schaltstellensymbol SSS auf dem Anzeigeschieber AZS - der Leistungsschalter ist nicht geschal- tet - der Vemegelungsschieber VRS m beiden Bewegungsrichtungen gesperrt und damit die Durchfuhrungsoffnung DUO sowie der Zugang zur Antriebsache ANA der Trenner und Erder verschlossen. Erst wenn der Leistungsschalter sich - wie dargestellt - im durchgeschalteten Zustand befindet, bei dem der senkrecht angeordnete Langsbalken m der Betrachtungsoffnung BEO das Abdeckbleches ABL sichtbar ist, wird die Sperrung des Verπegelungsschalters VRS aufgehoben und damit der Zugang zur Antriebsachse ANA der Trenner und Erder durch Verschieben des Vemegelungsschiebers VRS freigegeben. Nur m diesem Zu- stand ist also eine manuelle Betätigung der Trenner- und Erder-Kontakte möglich. FIG. 2 shows the control module STM with only a partial section of the cover plate ABL with the viewing opening BEO. Behind the cover plate ABL is the middle plate MBL with the holding plate HBL lying behind it. The center plate MBL has the guide opening FUO, in which the locking slide VRS and the indicator slide AZS can each be moved in the direction of the arrow. In the state shown, the display slide AZS is positioned so that the locking slide VRS can be moved in the direction of the arrows. The locking slide VRS and the display slide AZS are arranged in the center plate MBL in such a way that when the circuit breakers are switched on, when the display slide ASZ m is moved, the locking state of the locking slide VRS is effected in a simple manner. For example, with the m of the BEO viewing opening, the ABL cover plate can be seen on the crossbar of the SSS switching point symbol on the AZS indicator slide - the circuit breaker is not switched - the VRS locking slide is blocked in both directions of movement and thus the DUO opening and access to the ANA drive unit of the isolators and earth electrodes locked. Only when the circuit breaker is - as shown - in the switched-on state, in which the vertical longitudinal bar in the BEO viewing opening, the ABL cover plate is visible, is the locking of the locking switch VRS released and thus access to the drive axis ANA of the isolators and earth electrodes by moving release valve VRS released. Only with this stand, manual operation of the isolator and earth contacts is possible.
