Description

Kühleinrichtung für Drosselspulen In dem Hauptpatent 551 704 ist eine Kühleinrichtung für Drosselspulen beschrieben, die aus einer ein Kühlmedium fördernden Vorrichtung, z. B. Ventilator, und einem elektrisch angetriebenen Motor für diese Vorrichtung besteht. Der Motor ist bei dieser Anordnung an eine ihn speisende Hilfsspule angeschlossen, die im Streufeld der Drosselspule liegt und auf die von der Drosselspule auf induktivem Wege die für den Antriebsmotor erforderliche elektrische Energie übertragen wird.Cooling device for choke coils In the main patent 551 704 a cooling device for choke coils is described, which consists of a device conveying a cooling medium, for. B. fan, and an electrically driven motor for this device. In this arrangement, the motor is connected to an auxiliary coil feeding it, which is located in the stray field of the choke coil and to which the electrical energy required for the drive motor is inductively transferred from the choke coil.

Die Erfindung bezweckt eine Verbesserung der in dem Hauptpatent beanspruchten Anordnung. Nach der Erfindung wird als Antriebsmotor ein Motor mit einer spannungsabhängigen Charakteristik verwendet.The invention aims to improve that claimed in the main patent Arrangement. According to the invention, a motor with a voltage-dependent is used as the drive motor Characteristic used.

Als Antriebsmotoren können beispielsweise Wechselstromreihenschlußmotoren verwendet werden, deren Drehzahl, wie allgemein bekannt ist, von der Spannung abhängt. Es können jedoch auch gewöhnliche Gleichstrommotoren, und zwar Reihenschlußmotoren, oder Motoren mit Fremderregung verwendet werden, die über elektrische Ventile an die Hilfsspule angeschlossen sind.AC series motors, for example, can be used as drive motors can be used, the speed of which, as is well known, depends on the voltage. However, ordinary DC motors can also be used, namely series motors, or motors with separate excitation are used, which are connected via electrical valves the auxiliary coil are connected.

Die neue Anordnung ist deswegen besonders vorteilhaft, weil die in der den Motor speisenden Hilfsspule induzierte Spannung direkt dem Belastungsstrom der Drosselspule proportional ist. Infolgedessen ändert sich nämlich auch die Drehzahl des Antriebsmotors und damit die Kühlung der Drosselspule entsprechend der Belastung. Ist die Belastung der Drosselspule gering, so läuft der Motor langsam. Bei größerer Belastung dagegen steigt die Drehzahl des Motors und damit auch die Drehzahl und die Kühlleistung des Ventilators.The new arrangement is particularly advantageous because the in the voltage induced by the auxiliary coil feeding the motor directly to the load current proportional to the inductor. As a result, the speed also changes of the drive motor and thus the cooling of the choke coil according to the load. If the load on the choke coil is low, the motor runs slowly. With larger Load, on the other hand, increases the speed of the motor and thus also the speed and the cooling capacity of the fan.
