Embodiment Construction

[0057] figure 1 A schematic view of a production installation according to the invention for producing a low-resistance current-measuring resistor 1 as known in a similar form from EP 0 605 800 A1 is shown. The current-measuring resistor 1 consists of two plate-shaped connections 2, 3 made of copper or another conductive material and made of a resistor material such as The fabricated resistor element consists of 4. The resistor element 4 is arranged between the two connections 2 , 3 in the direction of current flow, whereby the connections 2 , 3 are used to introduce the current to be measured into the current-measuring resistor 1 or to let the current flow out of the current-measuring resistor .

[0058] To produce the current-measuring resistor 1, two copper strips 6, 7 and a resistor strip 8 are supplied to the welding station 5, where the copper strips 6, 7 and the resistor strip 8 are then welded along their longitudinal edges in the welding station 5. Together, to fo...

Abstract

A production method for an electrical resistor (1), in particular a low-resistance shunt, comprises the steps of providing a plate-shaped initial part (9) for the resistor (1), wherein the initial part (9) has a certain thickness and, in accordance with the thickness, a specific value of an electrical component characteristic (R), in particular the resistance thereof; rolling the initial part (9)with a specific degree of rolling (AG), wherein the thickness of the initial part (9) is reduced in accordance with the degree of rolling (AG) and the value of the component characteristic (R) is modified accordingly; measuring the thickness-dependent electrical component characteristic (R) at the rolled initial part (9); and adapting the degree of rolling (AG) depending on the measured electricalcomponent characteristic (R), in particular within the scope of a closed-loop control with the electronic component characteristic (R) as controlled variable and the degree of rolling (AG) as manipulated variable. Furthermore, the invention comprises a resistor produced accordingly and an according production installation.

Description

technical field [0001] The invention relates to a method for producing a resistor, in particular a low-resistance current-measuring resistor. Furthermore, the invention includes correspondingly produced resistors. Finally, the invention also includes a production plant for carrying out the production method according to the invention. Background technique [0002] A low-resistance current-measuring resistor is known from EP 0605800 A1, which can be used for current measurement according to the well-known four-wire technique. The current to be measured is conducted through the low-resistance current-measuring resistor, whereby the voltage drop across the current-measuring resistor is measured. According to Ohm's law, the voltage drop measured here corresponds to the current to be measured. [0003] Furthermore, a method for producing such a low-resistance current-measuring resistor is known from EP 0605800 A1. Conductor material (for example, copper) or resistor material ...
