Abstract
(DE)
Elektrische Maschine, umfassend einen Rotor-Wickelkopf und eine Vorrichtung zur Überwachung desselben, wobei die Vorrichtung ein Mikrowellen-Radarsystem umfasst, welches eine Sende- und Empfangseinheit, eine Sonde und ein Kabel umfasst, wobei die Sonde lanzenförmig ist, und wobei die Längsachse der Sonde in radialer Richtung angeordnet ist, und wobei sich die Sonde zwischen den Stator-Wicklungselementen erstreckt, und wobei die Sonde einen lanzenförmigen Träger, eine Antenne und elektrische Leiter umfasst, wobei der Träger aus unmagnetischen und nichtleitenden Materialien aufgebaut ist, und die Antenne am sensitiven Ende der Sonde angeordnet und mit dem Träger verbunden ist, und die elektrischen Leiter die Antenne mit dem Kabel verbinden und mit dem Träger verbunden sind, und die Sonde eine Spannungsisolation umfasst, welche den Träger, die Antenne und die Leiter umgibt.
(EN)
The invention relates to an electric machine comprising a rotor winding head and a device for monitoring same. The device comprises a microwave radar system which comprises a transceiver unit, a sensor, and a cable. The sensor is lance-shaped, and the longitudinal axis of the sensor is arranged in the radial direction. The sensor extends between the stator winding elements, and the sensor comprises a lance-shaped support, an antenna, and electric conductors. The support is made of non-magnetic and non-conductive materials, and the antenna is arranged on the sensitive end of the sensor and is connected to the support. The electric conductors connect the antenna to the cable and are connected to the support, and the sensor comprises a voltage insulation which surrounds the support, the antenna, and the conductors.

La présente invention concerne une machine électrique, comprenant une tête bobinée de rotor et un dispositif pour surveiller cette dernière. Le dispositif comprend un système radar à microondes qui comprend une unité d'émission et de réception, une sonde et un câble. La sonde présente une forme de lance, l'axe longitudinal de la sonde étant disposé dans la direction radiale. La sonde s'étend entre les éléments de bobinage du stator et comprend un support en forme de lance, une antenne et des conducteurs électriques. Le support est composé de matériaux non magnétiques et non conducteurs, l'antenne est disposée au niveau de l'extrémité sensitive de la sonde et est reliée au support, et les conducteurs électriques sont reliés à l'antenne via le câble et reliés au support. La sonde présente une isolation électrique qui entoure le support, l'antenne et les conducteurs.
