Abstract

In an arrangement to increase the thermal couple for a temperature sensor, the sensor is held within an insulating mantle and is linked to a measuring device by two wires, each with an insulating mantle. One of the insulating mantles is shorter than the other. The longer insulation provides greater heat couple than the shorter insulation.

Description

Temperatursensoren werden im Hauptanwendungsbereich als indirekt beheizte Sensoren eingesetzt. Es wird Wärme aus der Umgebung dem Sensor zugeführt.In the main application area, temperature sensors are used as indirectly heated sensors used. Heat from the surroundings is fed to the sensor.

Beim Anwendungsbereich der Elektromotoren werden häufig keramische Kaltleiter (oder andere Temperatursensoren) als Grenztemperaturfühler eingesetzt. Dies hat den Grund, dass diese Elektromotoren oft bis an ihre Leistungsgrenze betrieben werden. Damit das Risiko auf Überhitzung und damit Zerstörung der Wicklung vermindert wird, stecken Kaltleiter als Temperatursensoren in den Wicklungen.Ceramic PTC thermistors (or other temperature sensors) are used as limit temperature sensors. This is because these electric motors are often operated to their maximum capacity. So the risk is on Overheating and thus destruction of the winding is reduced, PTC thermistors are used as Temperature sensors in the windings.

Bei diesen hoch ausgelasteten Elektromotoren ist es sehr wichtig, dass die Sensoren sehr schnell dem Temperaturverlauf (z. B. der Wicklung usw.) folgen. Die zeitliche Verzögerung zwischen Wicklungs- und Sensortemperatur muss also möglichst klein sein.With these highly utilized electric motors, it is very important that the sensors work very well quickly follow the temperature curve (e.g. the winding, etc.). The time delay between the winding and sensor temperature must be as small as possible.

Bisher werden Werte der Ansprechzeiten (nach DIN 44081/44082) von kleiner 5 Sekunden erreicht.So far, the response times (according to DIN 44081/44082) have been less than 5 seconds reached.

Durch eine technische Änderung in der Konfektion der Temperatursensoren (Kaltleiter oder ähnliche Sensoren) wird erreicht, dass dieser Wert der Ansprechzeit erheblich unter 5 Sekunden liegt. Es werden Werte von kleiner 3 Sekunden erreicht.Due to a technical change in the assembly of the temperature sensors (PTC thermistor or similar sensors) it is achieved that this value of the response time is significantly below 5 Seconds. Values of less than 3 seconds are reached.

Ausführungs-BeschreibungExecution Description

Durch die gewollt einseitige längere Abisolierung der Anschlusslitze wird eine wesentliche Vergrößerung der Wärmekopplung (durch den freien Metalldraht) zu dem umgebenden Medium (z. B. Wicklung oder Ähnlichem) erreicht. Somit ist auch die zeitliche Verzögerung (Ansprechgeschwindigkeit) von dem umgebenden Medium und dem Temperatursensor kleiner.The deliberate, one-sided, longer stripping of the connecting strands becomes essential Enlargement of the heat coupling (through the free metal wire) to the surrounding one medium (e.g. winding or the like) reached. So there is also the time delay (Response speed) of the surrounding medium and the temperature sensor smaller.

In Fig. 1 ist dargestellt, wie die Temperatursensoren bisher gefertigt wurden (Standard und Stand der Technik).In Fig. 1 it is shown how the temperature sensors have been produced (standard and prior art).

In Fig. 2 ist der Temperatursensor dadurch gekennzeichnet, dass der eine Anschlussdraht länger abisoliert ist und dadurch eine größere Wärmekopplung zu dem umgebenden Medium hat. Die einseitig fehlende Anschlussdrahtisolierung verbessert den Wärmefluss zum Temperatursensor, da dies einer zusätzlichen Metallfläche gleich kommt.In Fig. 2, the temperature sensor is characterized in that the one connecting wire is stripped longer and thereby has a greater heat coupling to the surrounding medium. The missing wire insulation on one side improves the heat flow to the temperature sensor, since this is equivalent to an additional metal surface.

Vergrößerung der thermischen Kopplung an Temperatursensoren durch die Gestaltung der Anschlussdrähte. Durch eine einseitige längere Abisolierung der Anschlussdrähte (kann auch Litze oder Band sein) wird eine Vergrößerung der Metallfläche zur Wärmeaufnahme erreicht und damit eine größere Wärmekopplung (bzw. kleinere Wärmeübergangswiderstände) zu dem umgebenden Medium (wie z. B. Motorwicklung oder weitere thermisch leitende Medien). Die einseitige längere Abisolierung des Anschlussdrahtes hat den weiteren Vorteil, dass keine zusätzliche Isolierung an dem Anschlussdraht notwendig wird.Enlargement of the thermal coupling to temperature sensors through the design of the Leads. By one-sided longer stripping of the connection wires (can also Strand or ribbon) an increase in the metal area for heat absorption is achieved and thus a greater heat coupling (or smaller heat transfer resistances) to the surrounding medium (such as motor winding or other thermally conductive media). The Long-term stripping of the connecting wire has the further advantage that none additional insulation on the connecting wire is necessary.
