Embodiment Construction

[0022] figure 1 The represented means for regulating the intensity I of a strong current passing through an electric wire 1 consists of a ring-shaped magnetic sensor 2 surrounding the electric wire 1, a ring of conductive material 3 surrounding the electric wire, which conducts a high-frequency reverse current, adjusts the high-frequency reverse current The strength of the current to counteract the magnetic field H.

[0023] According to the invention, the loop 3 of conductive material is closed, thus short-circuited, and it surrounds the magnetic sensor 2 .

[0024] The resistance R of the loop 3 of short-circuited conductive material is adjusted to obtain an L / R filter constant, where L is the inductance of the loop 3 .

[0025] In the exemplary embodiment shown, this ring 3 is made of soft iron 4 and is surrounded from the outside by a copper sleeve 5 .

[0026] Such as figure 1 As shown, the inside of the ring 3 contains a channel 6 concentric with the torus of the ring...

Abstract

The invention relates to a device for measuring the intensity (1) of a strong current passing through a wire (1), said device comprising a magnetic sensor (2) in the form of a loop surrounding the wire (1), and an arc runner (3) which consists of a conductive material that surrounds the wire (1) and conducts a high frequency counter-current, the intensity of which is adjusted in order to cancel the magnetic field (H). The inventive device is characterised in that the arc runner (3) consisting of a conductive material is part of a short circuit and surrounds the magnetic sensor (2).

Description

technical field [0001] The invention relates to a device for regulating the strength of high currents passing through electric wires. Background technique [0002] The term "high current" refers to any current with a strength between 100A and 1000A. [0003] To regulate this high current, a magnetic field is usually created around the wires that conduct the current being regulated. [0004] In order to obtain a precise adjustment of this magnetic field, the so-called "counteraction" method is used. [0005] This method involves placing coils around the wire that conduct current in the opposite direction of the magnetic field, and adjusting the current to counteract the field. [0006] When the reverse current control loop is, for example, a system of frequency F0, components having frequencies higher than frequency F0 present in the regulated current can produce severe errors. Contents of the invention [0007] The object of the present invention is to produce a device ...
