Dabei greift der Sensorkopf (12) in einen zwischen zwei benachbarten Spulen (26) der Statorwicklung (27) gebildeten Zwischenraum (42) ein und befindet sich mit der Statorwicklung (27) im Wärmeübertragungskontakt. Die Spulen (26) sind aus seinem Wickeldraht (22) gewickelt und weisen auf deren zueinander zugewandten Oberflächen jeweils ein Flächenisolationselement (32, 34) auf. Es wird vorgeschlagen, den Temperatursensor (10) zwischen den Flächenisolationselementen (32, 34) der benachbarten Spulen (26) anzuordnen und zumindest in einem der zu dem Temperatursensor (10) benachbarten Flächenisolationselementen (34) eine Ausnehmung (34a) vorzusehen, in welche der Sensorkopf (12) eingreifen kann und sich in Anlagekontakt zu dem Wickeldraht (22) befindet.An arrangement (8) for temperature detection of a stator winding (27) of an electrical machine (36) is described with a temperature sensor (10) forming a substantially one-dimensional configuration and the end a sensor head (12) with connecting conductors (16a, b) having. The sensor head (12) engages in a gap (42) formed between two adjacent coils (26) of the stator winding (27) and is in heat transfer contact with the stator winding (27). The coils (26) are wound from its winding wire (22) and have on their mutually facing surfaces in each case a surface isolation element (32, 34). It is proposed to arrange the temperature sensor (10) between the surface isolation elements (32, 34) of the adjacent coils (26) and to provide a recess (34a) in at least one of the surface isolation elements (34) adjacent to the temperature sensor (10) into which the Sensor head (12) can engage and is in abutting contact with the winding wire (22).
Description
Die Erfindung betrifft eine Anordnung zur Temperaturerfassung einer Statorwicklung einer elektrischen Maschine gemäß dem Oberbegriff des Patentanspruchs, wie diese beispielsweise mit der
Der Erfindung liegt von dem genannten Stand der Technik ausgehend die Aufgabe zugrunde, eine gattungsgemäße Anordnung zur Temperaturerfassung mit einem verbesserten Ansprechverhalten und mit einer erhöhten Genauigkeit der Temperaturwerte darzustellen. The invention is based on the mentioned prior art, the object to represent a generic arrangement for temperature detection with improved response and with increased accuracy of the temperature values.
Die vorstehend genannte Aufgabe wird mittels einer Anordnung gemäß den Merkmalen des Patentanspruchs gelöst. The above object is achieved by means of an arrangement according to the features of the patent claim.
Gemäß der Erfindung wird eine Anordnung zur Temperaturerfassung einer Statorwicklung einer elektrischen Maschine vorgeschlagen mit einem Temperatursensor, der eine im Wesentlichen eindimensionale Konfiguration ausbildet und der endseitig einen Sensorkopf mit Anschlussleitern aufweist, wobei der Sensorkopf in einen zwischen zwei benachbarten Spulen der Statorwicklung gebildeten Zwischenraum eingreift und sich mit der Statorwicklung im Wärmeübertragungskontakt befindet. Die Spulen sind aus seinem Wickeldraht gewickelt und weisen auf deren zueinander zugewandten Oberflächen jeweils ein Flächenisolationselement, insbesondere ein Isolationspapier oder eine Isolationsfolie, auf. According to the invention, an arrangement for temperature detection of a stator winding of an electrical machine is proposed with a temperature sensor which forms a substantially one-dimensional configuration and the end has a sensor head with connecting conductors, wherein the sensor head engages in a gap formed between two adjacent coils of the stator winding and with the stator winding in the heat transfer contact. The coils are wound from its winding wire and have on their mutually facing surfaces in each case a surface insulation element, in particular an insulating paper or an insulating film on.
Bei dieser Anordnung ist vorgesehen, den Temperatursensor zwischen den Flächenisolationselementen der benachbarten Spulen anzuordnen und zumindest in einem der zu dem Temperatursensor benachbarten Flächenisolationselemente eine Ausnehmung, insbesondere ein Fenster an einer vorbestimmten Position einzubringen, in welche der Sensorkopf eingreifen und dadurch in Anlagekontakt zu dem Wickeldraht gebracht werden kann. Das Flächenisolationselement kann zur definierten Anbringung an einer Statorspule in einer vorbestimmten Weise vorgefalzt werden. In this arrangement, it is provided to arrange the temperature sensor between the surface isolation elements of the adjacent coils and at least in one of the temperature sensor adjacent to the surface isolation elements a recess, in particular introduce a window at a predetermined position, in which engage the sensor head and thereby brought into abutting contact with the winding wire can be. The surface isolation member may be pre-folded for defined attachment to a stator coil in a predetermined manner.
Eine Statorspule kann insbesondere als eine Einzelzahnwicklung unter Verwendung von einem oder zwei Wickelkörpern hergestellt sein, wobei das Flächenisolationselement in einer definierten Art und Weise von den Wickelkörpern aufgenommen wird. Auf diese Weise kann das vorgesehene Fenster gleichzeitig zur vorbestimmten Positionierung des Sensorkopfes an einer Statorspule genutzt werden. Beim Einführen des Temperatursensors kann der Sensorkopf bei Erreichen des Fensters in dieses zumindest teilweise eintauchen, so dass dieser dadurch innerhalb des Fensters fixiert ist. Die Fixierung kann durch eine auf den Temperatursensor einwirkende Kraft quer zur Fensterebene, zum Beispiel von einem Sensorträger, verstärkt werden. In particular, a stator coil may be fabricated as a single tooth winding using one or two bobbins, the surface isolation element being received in a defined manner by the bobbins. In this way, the intended window can be used simultaneously for the predetermined positioning of the sensor head on a stator coil. Upon insertion of the temperature sensor, the sensor head may at least partially submerge when it reaches the window, so that it is thereby fixed within the window. The fixation can be enhanced by acting on the temperature sensor force across the window plane, for example, from a sensor carrier.
Durch das Einbringen eines solchen Fensters können die thermische Anbindung des Temperatursensors, die Messdynamik und dessen Positioniergenauigkeit verbessert werden. By introducing such a window, the thermal connection of the temperature sensor, the measurement dynamics and its positioning accuracy can be improved.
Die Erfindung wird nachfolgend unter Bezugnahme auf die beiliegenden Figuren beispielhaft erläutert. The invention will now be described by way of example with reference to the accompanying drawings.
