Embodiment Construction

[0037] Parts with the same function and working method are in the figure 1 and figure 2 are marked with the same reference signs.

[0038] figure 1 A thermocouple 1 for temperature measurement of high-voltage components is shown schematically. The thermocouple 1 has a metallic first conductor 2 composed of a nickel-chromium alloy and a metallic second conductor 3 composed of nickel. Such as figure 1 As shown in the sectional view of , the first conductor 2 has a larger cross-sectional area than the second conductor 3 . Thereby, the first conductor 2 and the second conductor 3 are arranged mechanically asymmetric to each other. However, the first conductor 2 and the second conductor 3 are arranged electrically symmetrically to each other through the selected metal pairing. In this example, the first conductor 2 made of nickel-chromium alloy has a higher resistivity than the second conductor 3 made of nickel. Here, in order to achieve an ideal electrical symmetry, the cro...

Abstract

The present invention relates to a thermocouple (1) for measuring the temperature of a high-voltage component, having a metal first conductor (2) made of a first material and a metal second conductor(3) made of a second material, wherein the first material differs from the second material, wherein the first conductor (2) and the second conductor (3) are mechanically asymmetrical and electricallysymmetrical with respect to one another. The invention also relates to a temperature measuring system (10) having the thermocouple (1) according to the invention and to a method for producing a thermocouple (1) according to the invention.

Description

technical field [0001] The invention relates to a thermocouple for temperature measurement of high-voltage components, having a metallic first conductor made of a first material and a metallic second conductor made of a second material, wherein the first material is different from the second material. The invention also relates to a temperature measuring system with a thermocouple and a method for manufacturing the thermocouple. Background technique [0002] Temperature measurement by means of thermocouples has already been known in the prior art. A thermocouple of this type is known, for example, from JP 2016-011880 A2. [0003] Thermocouples typically produce very low voltages, ranging from about 6 μV / K to about 42 μV / K depending on the material pairing. In order to achieve a higher measurement accuracy, the thermocouples are therefore usually shielded so that voltage disturbances and thus the measurement results are influenced as little as possible. However, shielding ...
