Problems solved by technology

It is difficult to detect the temperature of cables in the above-mentioned places, and such places usually have the characteristics of concentrated power transmission by cables and large carrying capacity, and the heat generation of cables is large. Therefore, for power cables in such places, during the use of cables It is prone to accidents such as power interruption, fire, explosion and other accidents caused by the current carrying capacity exceeding the design carrying capacity of the cable, excessive temperature rise, heat accumulation, and heat concealment
At present, there is no detection equipment that can detect the temperature of cables in such places in real time, so the above problems need to be solved urgently

Embodiment 1

[0020] In this embodiment, the temperature display cable includes a conductive core and an outer sheath arranged outside the conductive core, and the cable also includes a temperature warning mark, and the temperature warning mark is set on the outer sheath or embedded in the outer sheath. In the outer sheath, the temperature warning sign can display different colors as its own temperature changes.

Embodiment 2

[0022] Such as figure 1 As shown, in this embodiment, the temperature display cable includes a conductive core 1 , an outer sheath 5 and a temperature warning sign 3 . Wherein, three conductive wire cores 1 are used, each conductive wire core is covered with an insulating layer 2 , and the outer sheath 5 is arranged outside the conductive wire core covered with the insulating layer 2 .

[0023] The temperature warning mark 3 can be set on the outer sheath 5 or embedded in the outer sheath 5 . In this embodiment, the temperature warning mark 5 is set on the outer sheath 5 . Wherein, the temperature warning sign can display different colors as its own temperature changes.

[0024] Wherein, the temperature warning sign 3 can be made of a color-changing material. The color-changing material can exhibit different colors under different ambient temperatures. In this embodiment, preferably, the color-changing material is made of a reversible color-changing material.

[0025] In ...

Embodiment 3

[0037] The difference between this embodiment and Embodiment 2 is that in this embodiment, the temperature display cable does not include a temperature display card.

[0038] Other structures and uses in this embodiment are the same as those in Embodiment 2, and will not be repeated here.

Abstract

The invention provides a temperature indicating cable which comprises conductive wire cores and an outer sheath arranged outside the conductive wire cores. The cable further comprises a temperature warning sign, the temperature warning sign is arranged on the outer sheath or embedded in the outer sheath, and the temperature warning sign can display different colors as the temperature thereof changes. The temperature indicating cable of the invention is simple in structure, can indicate the using temperature thereof in real time and has a positive effect in preventing power outage and the occurrence of fire and explosion accidents.

Description

technical field [0001] The invention belongs to the technical field of cables, and in particular relates to a temperature display cable. Background technique [0002] At present, in the power cable industry, whether it is a large-section large-capacity power transmission cable or a household small-carry-capacity cable, accidents such as power interruptions and fires often occur during use because the current carrying capacity exceeds the design carrying capacity and the temperature rise is too high. . In order to prevent the occurrence of the above-mentioned accidents, it is necessary to detect the wires and cables in real time. However, because the wires and cables are distributed products, that is, they are widely distributed, the lines are long, the environmental conditions along the lines are complex, and there are many influencing factors, so they cannot be well combined with temperature sensors. Causes problems such as incomplete, untimely, and discontinuous detection...
