Abstract

2.1 In the case of gas-insulated switching installations, specific drive openings and the cable connecting space must be closed during a switching process, for safety reasons. However, such locks have the disadvantage that they can easily be circumvented as soon as the cable connecting space is open. 2.2 The invention indicates a way in which it is possible to close this large security gap. For this purpose, an additional connecting element is inserted between a closeable opening (1) and the operating shaft (4) in such a manner that the operating shaft (2) is locked as soon as the closure device (3a or 3b respectively) is opened, and is released when the closure device (3a or 3b respectively) is closed. 2.3 Such locking systems are used in medium-voltage switching installations, preferably in metal-encapsulated, compressed-gas-insulated switching installations. <IMAGE>

Description

Die Erfindung betrifft eine Verriegelungseinrichtung für Betätigungsöffnungen von Schaltantrieben in gasisolierten Schaltanlagen gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a locking device for actuating openings of switch drives in gas-insulated switchgear assemblies.

Es ist bekannt, daß bei gasisolierten Schaltanlagen bestimmte Antriebsöffnungen aus funktionalen Sicherheitsgründen bei einem Schaltvorgang über den Schaltantrieb verschlossen sein müssen. Das gleiche gilt für den Kabelanschlußraum, die Tür muß verschlossen bzw. verriegelt werden können, so daß ein Öffnen der Tür nur unter bestimmten Voraussetzungen möglich ist.It is known that in gas-insulated switchgear, certain drive openings must be closed for functional safety reasons during a switching operation via the switching drive. The same applies to the cable connection space, the door must be able to be locked or locked so that the door can only be opened under certain conditions.

Eine Verriegelungseinrichtung nach dem Oberbegriff des Anspruchs 1 ist bereits bekannt (Werbeschrift von distrel PY, Jahrg. 3.79). Diese Verriegelungseinrichtung weist jedoch erhebliche Sicherheitsmängel auf, da diese Verriegelung bei jedem Schaltvorgang und zu jedem Zeitpunkt aufgehoben werden kann.A locking device according to the preamble of claim 1 is already known (advertising letter from distrel PY, year 3.79). However, this locking device has considerable safety deficiencies, since this locking can be released at every switching operation and at any time.

Eine weitere Verriegelungseinrichtung (Werbeschrift von PFI-STERER, Jahrg. 84) ist zudem bekannt. Bei dieser Verriegelungseinrichtung läßt sich die Fronttür und damit der Zugang zu den Sicherungsträgern nur öffnen, wenn der Erdungsschalter des Trafofeldes eingeschaltet wurde. Da aber jede weitere Verriegelung des Erdungsschalters fehlt, besteht auch hier die Gefahr, daß, sobald die Fronttür geöffnet ist, durch eine unsachgemäße Handhabung der Erdungsschalter in Ausstellung gebracht wird und so ein großes Sicherheitsrisiko für das Bedienungspersonal entsteht.Another locking device (advertising lettering from PFI-STERER, year 84) is also known. With this locking device, the front door and thus the access to the fuse carriers can only be opened if the earthing switch of the transformer field has been switched on. However, since any further locking of the earthing switch is missing, there is also the risk that, as soon as the front door is opened, improper handling of the earthing switch will result in a great safety risk for the operating personnel.

Der Erfindung liegt die Aufgabe zugrunde, eine weiterführende Ausbildung des Schaltsicherheitssystems für gasisolierte Schaltanlagen der eingangs geschilderten Art mit dem Ziel zu entwikkeln, daß, solange der Kabelanschlußraum nicht voll ständig wieder verschlossen und von außen mit einem Schloß oder Vorreiber verriegelt ist, die Betätigungsöffnungen für Ringkabel, Trafo oder Erder zusätzlich und sicher verschlossen werden können.The invention has for its object to develop a further training of the switching safety system for gas-insulated switchgear of the type described with the aim that as long as the cable connection space is not completely closed again and locked from the outside with a lock or sash, the actuating openings for ring cables , Transformer or earth electrode can also be locked securely.

Diese Aufgabe wird erfindungsgemäß mit den konstruktiven Merkmalen im Kennzeichen des Hauptanspruchs gelöst.This object is achieved with the design features in the characterizing part of the main claim.

Die mit der Erfindung erzielbaren Vorteile bestehen insbesondere darin, daß diese Verriegelungseinrichtung eine große Sicherheitslücke schließt und gewährleistet, daß eine unsachgemäße und damit gefährliche Schalthandlung nicht erfolgen kann und sie den Bedienenden grundsätzlich dazu zwingt, vor weiteren Schalthandlungen den Kabelanschlußraum zu verschließen bzw. zu verriegeln. Die Erfindung erlaubt jedoch auch das wahlweise Verschließen der Betätigungsöffnungen für ein Ringkabelfeld, sowie das Verschließen der Betätigungsöffnungen des Erdungsschalters in einem Trafofeld, was bei Wartungsarbeiten an Trafo-oder Trafozuleitungen und Sicherungen notwendig ist. Hierbei darf aus Sicherheitsgründen der Erder auf keinen Fall ausgeschaltet sein, er darf erst nach Wartung und Verschließen der Tür bzw. des Schlosses oder Vorreibers im Sicherungskabelanschlußraum wieder ausgeschaltet werden.The advantages that can be achieved with the invention are, in particular, that this locking device closes a large security gap and ensures that an improper and thus dangerous switching operation cannot take place and that it basically forces the operator to close or lock the cable connection space before further switching operations. However, the invention also allows the actuation openings for a ring cable field to be optionally closed, and the actuation openings of the earthing switch to be closed in a transformer field, which is necessary for maintenance work on transformer or transformer leads and fuses. For safety reasons, the earth electrode must never be switched off, it may only be switched off again after maintenance and locking of the door or the lock or sash lock in the safety cable connection compartment.

Vorteilhafte Aus- und Weiterbildungen des Gegenstandes nach Anspruch 1 sind den Unteransprüchen zu entnehmen.Advantageous training and further developments of the subject matter according to claim 1 can be found in the subclaims.
