2、 The Performance and Application of Irreversible Color Changing Temperature Measurement Patch

The irreversible color changing temperature measurement patch has unique color changing temperature indication, eye-catching display, and temperature recording functions. Equipped with pressure-sensitive adhesive, it is applied to the connection parts of substation busbars; It can also be attached to the connection between the busbar and the equipment wiring terminals, as well as to the contacts of the isolation switch; It can also be attached to the casing of electrical equipment such as transformers, capacitors, motors, etc., to monitor the temperature of the busbar connection and the casing of electrical equipment. Once the temperature of the monitoring area reaches or exceeds the rated temperature of the temperature measuring patch, the color changing temperature measuring patch will quickly change color. The color of the temperature measuring patch changes from white to black after exceeding the temperature, and the color change is noticeable. Whether during the day or night, it is easy for people to detect the temperature rise in the monitoring area during inspections, in order to identify potential faults and prevent accidents from occurring. If the temperature of the monitoring area is too high, causing the temperature measurement patch to overheat and discolor, and the temperature measurement patch does not return to its original color after cooling, it shows a recorded overheating state.

3、 Types and characteristics of irreversible color changing temperature measurement patches

1. The basic models and characteristics of irreversible color changing temperature measuring patches can be found in the table on the back.

2. The existing product model, temperature, size, and color have been determined. Customers can refer to the temperature gauge of the temperature measurement patch model to choose a suitable model for their own use. If the customer has special needs, production can be carried out according to the customer's requirements.

3. The error between the color change temperature of the color changing temperature measurement patch and the rated temperature is within ± 3 ℃.

4、 The usage method of irreversible color change temperature measurement patch

1. The irreversible color change temperature measurement patch is in the form of a label. As long as a color change temperature measurement patch with an appropriate rated temperature is selected, it can be directly pasted on the bus joint, knife switch, transformer shell and other parts that need to be monitored for temperature. The sticking area of the temperature measurement patch should be flat, clean, and dry. Use sandpaper to polish and remove the oxide film and rough surface, or clean and wipe once with solvents such as gasoline and acetone. Press firmly when pasting.

2. When using, if you want to know the gradual increase in temperature at the monitoring area, you can stick two or more color changing temperature measuring patches with different rated temperatures, or use multiple temperature combination type patches (each patch contains multiple rated temperatures).

3. Precautions: The pasting of color changing temperature measuring patches should be carried out when there is no electricity in the busbar or other monitoring areas, and safety regulations must be followed. If you want to paste temperature measurement patches with electricity, you need to use insulation rods of the corresponding level to assist in pasting.

5、 Storage and service life of irreversible color changing temperature measurement patches

1. The irreversible color change temperature measurement patch can be stored indoors at room temperature. It is odorless, non radiative, and non irritating to the skin. Irreversible color changing temperature measuring patches should be kept away from light and heat sources.

2. Due to the complexity of the on-site use of color changing temperature measuring patches, when the color changing temperature measuring patches are applied to the monitoring area, they can be used at normal temperature and environment, and remain white without exceeding the temperature. They can be used indoors for 4-6 years and outdoors for 2 years (specific results will be subject to actual environmental testing). The patch that has overheated and discolored should be replaced in a timely manner with maintenance.
