Problems solved by technology

However, no matter at home or abroad, most of the research and application in power grid fault monitoring are single-color low-temperature temperature-indicating materials, that is, only one color can change with temperature changes, and the color-changing temperature is basically below 200 ° C, so it is impossible to control the temperature by temperature. different types of faults, and it is impossible to collect fault temperature data with reference value
[0004] The development of smart grid puts higher requirements on the temperature monitoring and sensing system. The single-color low-temperature temperature-indicating material can no longer meet the needs of fault type detection and fault location temperature measurement in a large temperature range.

Abstract

The invention discloses a 300-900°C multi-color irreversible temperature-indicating material and its preparation method and application. The temperature-indicating material consists of the following components in mass percentage: colored pigment: 24-28.6%, filler 1: 7.5- 8.5%, filler 2: 14.5-18.7%, resin base material: 47-50%, the preparation method is as follows: Step 1, ingredients: weigh various components according to the proportion, first add colored pigments, grind and pulverize the solid particles, Then add filler 1 and filler 2 and mix evenly, and finally add resin base material and stir to make a color paste; Step 2, prepare temperature-indicating materials: transfer the color paste to a high-speed ball mill for grinding and dispersion, and ball mill to a fineness of 30 µm. The multi-color temperature-indicating material of the present invention has seven kinds of color changes in the range of 300-900°C, and the maintenance personnel can quickly judge the type of fault and the location of the fault by observing the colors of the materials in various parts of the power system.

Description

technical field [0001] The invention relates to a multi-color irreversible temperature-indicating material in a wide temperature range, a preparation method thereof and its application in temperature measurement and fault detection of various key parts in a power system. Background technique [0002] Today, the vigorous development of high-tech continues to promote the process of intelligent transformation of society, and the core of intelligent transformation is the Internet of Everything, and functional sensing materials are the key to the realization of the interconnection of all things, and it has also become a hot spot in the development of high-tech. In terms of temperature intelligent measurement and control sensing, the original infrared sensor has been unable to meet the requirements of large-scale multi-point real-time measurement and control of the Internet of Things due to reasons such as large hardware, high requirements for use, and expensive equipment.
