Abstract

The application is to motor controls produced in large numbers for identical applications, for example soot blowers in thermal power stations. The separate wiring of controls, for example overcurrent relays, timers, lockout devices, pole changing relays and the like is eliminated by making a printed circuit plate with all necessary power and light current connections. The components are then mounted directly onto the plate without wire connections and the whole connected into the motor supply. Wiring errors are eliminated. In the event of failure the whole board can be quickly replaced thus the motor down time is reduced.

Description

Steuerung von Drehstromantrieben bis 3 K@7500 VControl of three-phase drives up to 3 K @ 7500 V.

Die Erfindug betrifft die Steuerung menrerer gleichartiger Drehstromantriebe bis 3 Kw7500 V mit hohem Ansteuerungs-, Verriegolungs- und uberwachungsaufwand. The invention relates to the control of several similar three-phase drives Up to 3 Kw7500 V with high control, locking and monitoring costs.

bie Steuerungseinheit des antriebes umfaßt den gesamten Geräte- and Verdrahtangsumfang, wie z. B. wendeschütz- bzw. The control unit of the drive includes the entire device and Wiring scope, such as B. reversing contactor or

golwendeschützkombination, Steuerschütze, Zeitglieder, Schutzeinrichtung und Abgangskiemmen sowie die erforderlichen tilemmen für die Verriegelung der antriebe uterelnander.Gold reversing contactor combination, control contactors, timing elements, protective devices and exit terminals as well as the required terminals for locking the drives uterelnander.

Die Verdrahtung der einzelnen Geräte für einen Antrieb erfolgt mittels flexibler aderleitungen, die konfektioniert oder manuell angefertigt werden. Die Verlegung dieser Leitungen wird grundsatzlich manuell ausgeführt. Abgesehen von der Fehlerquote, erfordert diese Technik einen hohen Montageaufwand und damit enorme Kosten. Zum Beispiel seien hier Rüßblässeranlagen in Großkraftwerken genannt, die heute zwischen 200 und 250 gleichartige Antriebe haben. The individual devices for a drive are wired using flexible wires that are assembled or made manually. the The laying of these lines is generally carried out manually. Apart from the error rate, this technology requires a high installation effort and therefore enormous Costs. For example, sootblower systems in large power plants are mentioned here today have between 200 and 250 drives of the same type.

Der Erfindung liegt die Aufgabe zugrunde, die Steuerung solcher antriebe so zu vereinfacnen, daß der montage- und der viceaufwand sowie der erforderliche flatzbedarf auf ein Minimum gesenkt werden kann. The invention is based on the task of controlling such drives to be simplified in such a way that the installation and service costs as well as the required space requirements can be reduced to a minimum.

Diese aufgabe ist gemaß der erfindung gelöst worden durch die Verwendung einer leiterplatine für den gesamten Leistungs- und Steuerungsteil eines Drehstromantriebes. Der gedruckten Schaltung bzw. Verdrahtung, wie sie im Bereich der Elektronik erfolgreich angewendet wird, ist damit eine neuartige Enwendung erschlossen worden. Der gesamte Leistungs- und Steuerungsteil wird erfindungsgemäß auf einer auswechselbaren platine, mit der entsprechenden gedruckten schaltung, aufgebaut.According to the invention, this object has been achieved through the use a circuit board for the entire power and control part of a three-phase drive. The printed circuit or wiring, as they are successful in the field of electronics is used, a new type of application has thus been opened up. The whole According to the invention, the power and control part is on a replaceable circuit board, with the corresponding printed circuit.

Durch die Zusammenfassung aller Geräte wie wende bzw. lolwendeschützkombinationen, Dteuerschütze, Zeitglieder, Schutzeinrichtung sowie der Abgang£ und Verriegelungsklemmen auf einem Bauelement entfällt die interne Verdrahtung und die Abgangsklemmleiste einschließlich der Verdrahtung. By combining all devices such as reversing or reversing contactor combinations, Control contactors, timers, protective devices as well as the output £ and locking terminals There is no internal wiring and output terminal strip on one component including wiring.

Durch diese erfindungsgemäße Lösung der gestellten Aufgabe wird vorteilhaftereise erreicht, daß durch Anwendung der gedruckten Schaltung der Verdrahtungsaufwand auf ca. 30 So reduziert wird. Dabei können ebenfalls mögliche Verdiahtungsfehler ausgeschaltet werden. Die Austauschbarkeit gewährleistet eine große Betriebsbereitschaft und kurze Ausfallzeiten in Störungsfall und die kompakte Ausführung senkt den Platzbedarf. Durch den Austausch der gesamten Steuerung im Störungsfall werden uie lästigen Reparaturfohler ebenfalls vermieden Die deparatur der Platine, d. h. der Austausch eines Gerätes kann in E.-Werkstätten ohne dchwierigkeiten vorgenommen werden0 This inventive solution to the problem posed is advantageous when traveling achieved that by using the printed circuit, the wiring effort about 30 so is reduced. Possible wiring errors can also be eliminated will. The interchangeability ensures a high operational readiness and short Downtimes in the event of a malfunction and the compact design reduce space requirements. Replacing the entire control system in the event of a malfunction can result in annoying repairs also avoided the repair of the circuit board, i. H. the replacement of a device Can be carried out in E. workshops without difficulty
