A wire and cable high temperature warning sticker

Abstract

The invention discloses a wire and cable high-temperature warning sticker which comprises a first shell. A glass plate is fixed in the middle of the side wall face of the first shell, a color comparison bar is fixed on the outer side of the side wall face of the first shell, the upper-end edge of the first shell is hinged to that of a second shell, one faces, close to each other, of the first shell and the second shell are provided with side wall faces, a sealing layer is fixed on a side face, close to the first shell, of the second shell, and buckles are fixed at the lower ends of the first shell and the second shell. The problem of detecting wire and cable temperature is solved by utilizing a reversible temperature-sensitive sticker, and the wire and cable high-temperature warning sticker is low in cost, convenient to use and easy in popularization; by arranging an elastic sticker fixing device, the device is ensured to be capable of being mounted on wires or cables different in size, and contact area between the sticker and the wires or the cables can be increased through stretching; the sticker can be taken down from the sticker fixing device easily, so that convenience is brought to replacement during maintenance.

Description

technical field [0001] The invention relates to the electrical field, in particular to a wire and cable high temperature warning sticker. Background technique [0002] The reversible temperature-sensing sticker can be regarded as a simple thermometer. It does not directly display the temperature value, but directly displays the approximate temperature range above a certain temperature, especially the temperature beyond the long-term safe operation of wires and cables. Through the temperature-sensitive color, it plays an obvious warning role for the operator. Then it is judged whether it is necessary to terminate power consumption, power outage maintenance, and troubleshoot. No battery or other kinetic energy is needed, as long as the temperature enters the warning range, the patch will start to change color, so as to remind the user of the temperature range and change.

AI Technical Summary

Problems solved by technology

[0003] The current heating of wires and cables for industrial and civil use is a sign of aging, failure or overload use, which is prone to danger and is not easy to detect. For most users, they are restricted by professional level, temperature changes and observation methods. The temperature threshold used to detect wires and cables is not easy to judge

Moreover, there are few similar applications on the market. Most of them use thermometers or temperature sensors and signal electronic temperature display screens to display temperature or warnings. They need batteries or power sources to work. The structure is complicated, electricity is required, and the cost is very high. , not easy to popularize
