Description
Die Erfindung geht aus von bekannten Schaltstellungsanzeigen
und -verriegelungen für Leistungsschalteranlagen, insbesondere
für luftisolierte Mittelspannungs-Schaltanlagen, mit den
Funktionsmerkmalen "Leistungsschalten", "Trennen" und "Erden".
Leistungsschalteranlagen mit diesen Funktionsmerkmalen sind
hinreichend bekannt und sind entsprechend den einschlägigen
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.
Die Stellungsanzeigen der Leistungsschalteranlagen und die
funktionellen Verriegelungen sind, wie beispielsweise aus der
DE 44 45 081 A1 ersichtlich, weitestgehend durch individuelle
Hebelgestänge gesteuert und dementsprechend sehr eng an die
konstruktiven Gegebenheiten der unterschiedlichen Leistungsschalteranlagen
angepaßt. Je nach Art und Ausbau der
Leistungschalteranlagen sind somit verschiedenartigste Steuermechanismen
mit sehr unterschiedlichen Einbauvolumen vorgesehen,
deren Vielfalt mit zunehmenden Kundenwünschen entsprechend
hoch ist. Neben den entsprechend notwendigen Anpassungsentwicklungen
bei schon geringfügigen konstruktiven Veränderungen
bestehender Leistungsschalteranlagen sind insbesondere
für neu entwickelte Anlagenkonzepte stets auch aufwendige
Neuentwicklungen in Bezug auf die Schaltsteliungsanzeigen
und -verriegelungen für die Leistungsschalteranlagen
notwendig. Die der Erfindung zugrunde liegende Aufgabe besteht
darin, die Vielzahl der unterschiedlichen Konstruktionen
bei den Schaltstellungsanzeigen und -verriegelungen für
die Leistungsschalteranlagen erheblich zu verringern und
darüber hinaus das Einbauvolumen dieser Schaltstellungsanzeigen
und -verriegelungen merkbar zu reduzieren.
Erfindungsgemäß wird dies durch die Merkmale
Circuit breaker systems with these functional features 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 and for interlocking the functions to be excluded at the same time in accordance with VDE 0670 Part 6 (interlocks / recommendations).
The position indicators of the circuit breaker systems and the functional interlocks, as can be seen, for example, from DE 44 45 081 A1, are largely controlled by individual lever linkages and are 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 adaptation developments in the event of even minor structural changes to existing circuit breaker systems, complex new developments with regard to the switch position indicators and interlocks for circuit breaker systems are always necessary, especially for newly developed system concepts. The object on which the invention is based is to considerably reduce the large number of different constructions in the switch position indicators and interlocks for the circuit breaker systems and, moreover, to markedly reduce the installation volume of these switch position indicators and interlocks. According to the invention, this is due to the features
Mit der Integration der Schaltstellungsanzeigen und der Schaltstellungsverriegelungen in einem gemeinsamen Steuermodul sind die konstruktiven Voraussetzungen für ein einheitliches Steuerungskonzept für Leistungsschalteranlagen auch mit unterschiedlichen Leistungsmerkmalen gegeben. Die Steuermodule sind in sogenannter "sandwich" - Bauweise ausgeführt, wobei die Schaltstellungsanzeigen als Anzeigeschieber und die Schaltstellungsverriegelungen als Verriegelungsschieber realisiert sind. Die Anzeigeschieber und die Verriegelungsschieber sind dabei in einem Mittelblech geführt, das frontseitig durch ein Abdeckblech mit entsprechenden Betrachtungsöffnungen und anlagenseitig durch ein Halteblech mit entsprechenden Durchführungsöffnungen begrenzt ist. Das Steuermodul ist als kompakte Baueinheit ausgestaltet und kann als standardisierte Baugruppe unabhängig vom Leistungsumfang der Leistungsschalteranlagen in dieselben eingesetzt werden.With the integration of the switch position indicators and the Switch position locks in a common control module are the constructive requirements for a uniform Control concept for circuit breaker systems also with different performance characteristics. The control modules are designed in a so-called "sandwich" construction, whereby the switch position indicators as indicator slides and the Switch position locks implemented as locking slides are. The indicator slides and the locking slides are guided in a center plate, the front through a cover plate with corresponding viewing openings and on the plant side by means of a holding plate with corresponding Feedthrough openings is limited. The control module is as designed compact unit and can be standardized Module independent of the scope of performance of the circuit breaker systems are used in the same.
Gemäß einer vorteilhaften Ausgestaltung der Erfindung sind
die Merkmale
Mit der gradlinigen Führung der Anzeigeschieber und der Verriegelungsschieber im Mittelblech ist in 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 middle plate is particularly simple Way a locking and free state of the locking slide reached.
Eine weitere vorteilhafte Ausgestaltung der Erfindung sieht
die Merkmale
Mit dieser festen Zuordnung zu den verschieden Komponenten der Leistungsschalteranlagen sind erleichterte und weitestgehend fehlerfreie Bedienungsweisen in den Schaltwarten ermöglicht.A further advantageous embodiment of the invention sees the features
This fixed assignment to the various components of the circuit breaker systems enables easier and largely error-free operation in the control rooms.
Eine weitere vorteilhafte Ausgestaltung der Erfindung ist
durch die Merkmale
Die weitestgehend fehlerfreien Bedienungsweisen in den Schaltwarten werden durch diese Merkmale noch zusätzlich gefördert.A further advantageous embodiment of the invention is due to the features
The largely error-free operating methods in the control rooms are further promoted by these features.
Die Erfindung wird durch ein in zwei Figuren dargestelltes Ausführungsbeispiel näher erläutert, wobei die
- Figur 1
- die Stirnansicht des Steuermoduls im Schnitt darstellt und die
- Figur 2
- die Forderansicht des Steuermoduls mit entferntem Abdeckblech zeigt.
- Figure 1
- the front view of the control module in section and the
- Figure 2
- 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, in
deren Ausnehmungen der Anzeigeschieber AZS eines nicht dargestellten
Leistungsschalters und der Verriegelungsschieber VRS
der ebenfalls nicht dargestellten Trenner und Erder geführt
sind. Das Mittelblech MBL ist frontseitig durch das Abdeckblech
ABL und anlagenseitig durch das Halteblech HBL begrenzt.
Durch den unterbrochenen Linienzug ist der Steuerungskomponenetenbereich
SKB angedeutet, in dem die zur Steuerung
der Leistungsschalter sowie der Erder und Trenner notwendigen
Schaltgestänge entsprechend räumlich angeordnet
sind.
Weiterhin sind in dieser Ansicht die Führungsöffnung FUO im
Mittelblech MBL und die Durchführungsöffnung DUO im Halteblech
HBL angedeutet.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, in the recesses of which the indicator slide AZS of a circuit breaker, not shown, and the locking slide VRS of the isolator and earth electrode, 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 switching linkages required for controlling the circuit breakers as well as the earthing and isolating devices are arranged correspondingly in space.
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 Teilausschnitt
des Abdeckbleches ABL mit der Betrachtungsöffnung
BEO. Hinter dem Abdeckblech ABL befindet sich das Mittelblech
MBL mit dem dahinterliegenden Halteblech HBL. Das Mittelblech
MBL weist die Führungsöffnung FUO auf, in der der Verriegelungsschieber
VRS und der Anzeigeschieber AZS jeweils in
Pfeilrichtung verschiebbar sind. Im dargestellten Zustand ist
der Anzeigeschieber AZS so positioniert, daß der Verriegelungsschieber
VRS in den Pfeilrichtungen verschiebbar ist.
In dem Mittelblech MBL sind der Verriegelungsschieber VRS und
der Anzeigeschieber AZS derart angeordnet, daß bei eingeschalteten
Leistungsschaltern mit dem Verschieben der Anzeigeschieber
ASZ in einfacher Weise der Sperrzustand der Verriegelungsschieber
VRS bewirkt ist. So ist beispielsweise mit
dem in der Betrachtungsöffnung BEO das Abdeckbleches ABL erkennbaren
Querbalken des Schaltstellensymbol SSS auf dem Anzeigeschieber
AZS - der Leistungsschalter ist nicht geschaltet
- der Verriegelungsschieber VRS in beiden Bewegungsrichtungen
gesperrt und damit die Durchführungsöffnung 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 Längsbalken in der Betrachtungsöffnung
BEO das Abdeckbleches ABL sichtbar ist, wird die Sperrung des
Verriegelungsschalters VRS aufgehoben und damit der Zugang
zur Antriebsachse ANA der Trenner und Erder durch Verschieben
des Verriegelungsschiebers VRS freigegeben. Nur in diesem Zustand
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 behind. The center plate MBL has the guide opening FUO, in which the locking slide VRS and the display 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 arrow.
The locking slide VRS and the indicator slide AZS are arranged in the center plate MBL in such a way that when the circuit breakers are switched on, when the slide indicator ASZ is moved, the locking state of the locking slide VRS is effected in a simple manner. For example, with the crossbar of the switching point symbol SSS on the display slide AZS - the cover plate ABL can be seen in the viewing opening BEO - the circuit breaker is not switched - the locking slide VRS is blocked in both directions of movement and thus the through opening DUO and the access to the drive unit ANA of the isolators and earth electrodes locked. Only when the circuit breaker is - as shown - in the closed state, with the vertical bar in the viewing opening BEO the cover plate ABL visible, is the locking of the interlock switch VRS released and thus access to the drive axis ANA of the isolators and earth electrodes by moving of the locking slide VRS released. The isolator and earthing contacts can only be operated manually in this state.
