Abstract
Ein Stromsensor (10) mit einem Substrat (70), einer Führungsrille (15) zur Aufnahme des Leiters (20), wobei die Führungsrille (15) in dem Substrat (70) eingebracht ist, einem unteren, magnetischen Kern (30u), der in das Substrat (70) integriert ist, und einem Oberteil (80) mit einem oberen, magnetischen Kern (30o). Der untere, magnetische Kern (30u) und der obere, magnetische Kern (30o) bilden gemeinsam einen Ringkern (30) um eine Führung (15) und weisen einen Spalt (40) mit einem magnetischen Sensor (50) auf.A current sensor (10) having a substrate (70), a guide groove (15) for receiving the conductor (20), wherein the guide groove (15) is incorporated in the substrate (70), a lower magnetic core (30u) integrated into the substrate (70), and a top (80) having an upper magnetic core (30o). The lower magnetic core 30u and the upper magnetic core 30o together form a toroidal core 30 around a guide 15 and have a gap 40 with a magnetic sensor 50.
Description
Die Erfindung betrifft einen Stromsensor.The invention relates to a current sensor.
Aus dem Stand der Technik ist eine Vielzahl von Stromsensoren bekannt. Zum Beispiel offenbart das Europäische Patent Nr.
Aus der US Patentanmeldung Nr.
Aus dem US Patent Nr.
Ebenfalls ist aus dem japanischen Patent Nr.
Das
Die bisherigen bekannten Stromsensoren offenbaren allerdings keine Lösung, bei der der fließende Strom durch mehrere Leiter gleichzeitig und unabhängig voneinander erfasst und gegebenenfalls gemessen wird. Darüber hinaus sind die bekannten Lösungen weder in einem Stecker noch in einem Substrat voll integriert und benötigen deswegen zusätzlichen Platz auf der Oberfläche bzw. neben dem Stecker.The previously known current sensors, however, do not disclose a solution in which the flowing current is detected by several conductors simultaneously and independently of each other and optionally measured. In addition, the known solutions are fully integrated neither in a plug nor in a substrate and therefore require additional space on the surface or next to the plug.
Dieses Dokument lehrt einen Stromsensor mit einem Substrat und einem Oberteil. Das Substrat und/oder das Oberteil enthält eine Mehrzahl von Führungen, welche in dem Substrat bzw. in dem Oberteil eingebracht sind und stromführende Leiter aufnehmen können. Das Substrat hat einen unteren, magnetischen Kern, welcher in das Substrat integriert ist, und das Oberteil hat einen dazu passenden oberen, magnetischen Kern. Der untere, magnetische Kern und der obere, magnetische Kern bilden gemeinsam einen Ringkern mit einem Spalt um eine der Führungen. Ein magnetischer Sensor ist in dem Spalt eingebracht, um fließenden Strom in Leitern in den Führungen zu erfassen.This document teaches a current sensor with a substrate and a top. The substrate and / or the upper part contains a plurality of guides, which are incorporated in the substrate or in the upper part and can receive current-carrying conductors. The substrate has a lower magnetic core integrated into the substrate, and the upper has a mating upper magnetic core. The lower magnetic core and the upper magnetic core together form a toroidal core with a gap around one of the guides. A magnetic sensor is placed in the gap to detect flowing current in conductors in the guides.
In einem Aspekt der Erfindung ist der magnetische Sensor ein magnetempfindliches Bauelement z.B. Hall-Sensor. Die in den Führungen angeordneten Leiter können durch einen Steckstift durch das Substrat bzw. Oberteil kontaktiert werden. Der magnetische Sensor ist mit einem Rechenwerk verbunden, welcher die Signale aus dem magnetischen Sensor verarbeitet und Meldungen über den Stromfluss in den Leitern über einen Bus weitergibt. In one aspect of the invention, the magnetic sensor is a magnetosensitive device, e.g. Hall sensor. The conductors arranged in the guides can be contacted by a plug pin through the substrate or upper part. The magnetic sensor is connected to an arithmetic unit, which processes the signals from the magnetic sensor and passes messages about the current flow in the conductors via a bus.
Diese Vorrichtung ermöglicht die Integration von einer unbegrenzten Vielzahl von Stromsensoren
Die Vorrichtung kann auch verwendet werden, um die elektrische Leistung zu messen. Der Strom in den elektrischen Leitern wird durch die magnetischen Sensoren gemessen. Die Spannung in den jeweiligen Leitern wird durch einen Kontaktstift abgegriffen und die elektrische Leistung aus der Differenz in den Spannungswerten auf den jeweiligen Leitern und den erfassten Stromwerten berechnet. The device can also be used to measure the electrical power. The current in the electrical conductors is measured by the magnetic sensors. The voltage in the respective conductors is tapped by a contact pin and the electrical power is calculated from the difference in the voltage values on the respective conductors and the detected current values.
Die Vorrichtung ermöglicht somit eine Selbstdiagnose vermittels des fließenden Stroms in einem Stecker.The device thus enables self-diagnosis by means of the flowing current in a plug.
Zum besseren Verständnis wird die Erfindung nun an Hand einer Ausführungsform und Zeichnungen näher erläutert. For a better understanding, the invention will now be explained in more detail with reference to an embodiment and drawings.
