Power thermal imaging camera escorts power equipment

Power equipment needs to operate stably, and it needs the help of high-tech products. Power infrared thermal imager is a powerful tool to detect power equipment failure. It can smoothly detect various internal and external problems of the equipment and provide a reliable basis for the successful completion of equipment maintenance. During the operation of the power system, current-carrying conductors will have resistive losses due to current effects. Do not underestimate the loss of this point, and accumulating over many years is also very scary. With the numerous interfaces and contacts of the wires, the accumulated losses are even more terrible. Because the resistance loss will generate heat, causing local temperature is too high, resulting in temperature differences with other parts, which can easily be found by the power infrared thermal imager, timely detection of problems and timely solution. Avoid the waste of many power resources.

From the perspective of internal faults, the high-voltage electrical equipment is enclosed in solid insulation and the failure of the electrical circuit inside the device housing and the breakdown of the insulation medium. These failures are internal to the equipment and surrounded by insulating media, reflecting the fact that the temperature rise on the outside of the equipment is not very strong. Therefore, the sensitivity of the testing equipment is higher. Internal faults require very high detection of infrared devices. Electric thermal imaging cameras have long been used in the safety inspection of electric equipment. Although electric thermal imaging cameras are expensive, they are also worthwhile. It can be used for transformers, bushings, circuit breakers, switches, transformers, power capacitors, surge arresters, power cables, busbars, conductors, combinational appliances, insulator strings, low-voltage electrical appliances, and devices with current, voltage heating, or other heating effects. The secondary circuit, etc., can be quickly resolved as long as the temperature is too high. Can discover the thermal defect of electrical equipment in time, (thermal defect of electrical equipment, usually refers to the detection through certain means, due to its internal or external causes of the heating phenomenon) This is very good for the prevention of major accidents. Avoid a lot of unnecessary property damage.

The temperature rise generally has the following reasons:

1. Parts that are exposed to the air for long periods of time, due to the effects of temperature and humidity, or poor contact due to surface fouling, or damage due to the action of external forces, resulting in reduced heat generated by the conductive cross-sectional area.

2. Due to the internal fault of the appliance itself, such as the internal connection parts, the resistance caused by poor contact is too large; the insulation material is aged, cracked, and dropped off; the internal components are damp, the loss of vital components increases; the cooling medium pipeline is blocked and so on.

3. The internal fault of the electric appliance itself, such as the excessive resistance due to the poor connection of the internal connection components; the aging, cracking, and loss of the insulating material; the dampening of the internal components, the increased loss of the vitality components; the blocking of the cooling medium pipeline, etc.

Some electrical components can be seen directly in the periphery. Power infrared cameras can find all kinds of thermal defects smoothly, and can eliminate hidden dangers in time. If they are not on the outer surface, they are in the part where the content is covered, then the thermal imager is needed. More analysis can lead to a better conclusion. According to the local temperature, air volume, electric load, etc. This requires the operator to have a very skilled operation method for the power infrared camera, as well as years of work experience. The power infrared thermal imager is capable of imaging the thermal state of the device without stopping, not contacting, remotely, quickly and intuitively. Whether the heat distribution of the power equipment is normal or not in the operating state is an important feature to determine whether the equipment is in good condition. Therefore, the use of infrared imaging technology can be used to diagnose the state of the equipment and its hidden defects by analyzing the thermal image of the equipment in a timely and accurate manner.
