Problems solved by technology

[0002] At present, the working temperature of the commonly used conductive wire will continue to rise after it is energized, especially when the conductive wire is partially damaged, resulting in poor contact or excessive load, etc., the working temperature will rise sharply, which is easy to cause Fire, which poses a threat to the safety of life and property, so the use of conductive wires has its potential dangers
Taiwan's new patent No. 265724 "Temperature sensor for power line load" discloses a structure that uses an electronic device to warn of abnormal power line load, but its volume is large, it takes up a certain amount of space when used, and the cost is high

Embodiment 1

[0037] Embodiment 1 of the present invention, such as figure 1 As shown, the outer edge of the conductive wire 1 is provided with a colored insulating layer 11, and the outer edge of the insulating layer 11 is covered with thermochromic ink 2 of different colors. The thermochromic ink 2 is printed on the insulating layer. On the layer 11, it has a critical discoloration temperature. When the operating temperature reaches or exceeds the critical discoloration temperature, the thermochromic ink 2 becomes transparent.

[0038] When in use, when the conductive wire 1 starts to be energized (such as figure 2 As shown), the working temperature will rise accordingly. When the working temperature is abnormal and reaches or exceeds the critical color changing temperature of the thermochromic ink 2, the thermochromic ink 2 will change color and become transparent, making the temperature sensitive The color of the insulating layer 11 under the color-changing ink 2 emerges, so that the ...

Embodiment 2

[0041] Embodiment 2 of the present invention, such as Figure 4 As shown, a green segment 3A, a yellow segment 3B and a red segment 3C are arranged on the insulating layer 11 of the conductive wire 1, and the green segment 3A, the yellow segment 3B, and the red segment 3C are correspondingly coated with the first A first thermochromic ink 4A with a critical discoloration temperature, a second thermochromic ink 4B with a second critical discoloration temperature, and a third thermochromic ink 4C with a third critical discoloration temperature, wherein the first critical discoloration temperature< The second critical discoloration temperature

Embodiment 3

[0043] Embodiment 3 of the present invention, as Figure 6 As shown, the colored thermochromic ink 6 is mixed into the insulating layer 51 of the conductive wire 5 . During use, when the operating temperature of the conductive wire 5 reaches or exceeds the critical discoloration temperature of the thermochromic ink 6, the thermochromic ink 6 will change color and become transparent ( Figure 7 shown) to change the color of the insulating layer 51 to produce a warning effect.

Abstract

The disclosed monitor method for wire temperature comprises: coating or doping temperature-sensitive color ink into the wire insulation layer, and the ink color or wire color changing as the abnormal change of wire temperature. This invention can provide fast alarming for safe application.

Description

technical field [0001] The invention is a method for monitoring the abnormal working temperature of the conductive wire. The insulating layer of the conductive wire is coated or mixed with temperature-sensitive color-changing ink. When the working temperature of the conductive wire changes abnormally, the color can be changed to generate a warning effect. Methods. Background technique [0002] At present, the working temperature of the commonly used conductive wire will continue to rise after it is energized, especially when the conductive wire is partially damaged, resulting in poor contact or excessive load, etc., the working temperature will rise sharply, which is easy to cause Fire poses a threat to the safety of life and property, so the use of conductive wires has its potential danger.
