Various electrical equipment and equipment, whether it is a switchboard or an outdoor clock box, whether it is stationary or rotating, as long as there is current flowing, it will generate heat. In rotating equipment, it will generate heat due to the friction between the movable part and the fixed part.

Temperature rise, this temperature rise is usually saturated within a certain temperature below the rated temperature, and the equipment can operate continuously. In the event of electrical or mechanical failure, the temperature will rise above the rated temperature due to temperature changes. Therefore, electrical equipment can judge whether there is a fault based on whether the temperature is higher than normal. The method of measuring electrical equipment faults through a customized infrared pyrometer is as follows.

1. Touch by hand

Because the temperature reflected by this method varies from person to person, the experience and habits of the device are very important. If you often consciously experience the normal temperature of the machine, it is not difficult to judge the abnormal temperature. The temperature that can be touched by the hand is about 60.

2. Paste the temperature indicating film

Apply temperature-indicating paint, busbar joints, blades of isolating switches and other parts that generate heat locally. If you cannot touch with your hands when there is electricity during operation, please paste the temperature-indicating film or apply the temperature-indicating paint. The temperature is measured when the color changes with temperature. There are many good temperature indicator films and paints. In addition, there are also varieties that appear in numbers at a specified temperature. The temperature indicator tape around 60 will reflect the subtle changes in temperature.

3. Use customized infrared pyrometer

Fixed installed customized infrared pyrometer, especially the parts that need to monitor temperature, such as motor bearings and stator windings, transformer oil and various coolers, are installed with ordinary thermometers or temperature sensors, and the temperature can be understood by visual inspection or instrumentation.
