Problems solved by technology

At present, most power users use low-voltage and high-current electrical equipment. Once the electrical equipment fails, it will easily cause high temperature.
At the same time, poor contact of electrical equipment will cause high temperature, ignition, arc, and easily become the ignition source of fire. Such dangerous temperatures and hidden dangers are usually not easy to be found
[0003] Traditional temperature monitoring technology is affected by many factors, especially for internal faults of electrical equipment, it is difficult to directly detect and judge, and it will also cause misjudgment

Embodiment Construction

[0011] see figure 1 As shown, the electrical equipment fault diagnosis system based on thermal map analysis method includes an infrared lens, and the infrared lens is aimed at the electrical equipment under test. The output end of the cooling infrared focal plane array detector is connected to the input end of an acquisition card, and the output of the acquisition card is connected to the host computer; the infrared lens captures the infrared rays radiated by electrical equipment, and the uncooled infrared focal plane array detector obtains the infrared lens acquisition Infrared radiation information, using photoelectric information conversion to achieve target imaging, the acquisition card converts the analog video signal output by the uncooled infrared focal plane array detector into a digital signal and then sends it to the host computer, the host computer performs a thermal image of the electrical equipment under test The power correction and distance correction are perfor...

Abstract

The invention discloses an electrical equipment fault diagnosis system based on a thermal pattern analysis method. The electrical equipment fault diagnosis system comprises an infrared camera lens; the infrared camera lens is aligned to electrical equipment to be detected; the output end of the infrared camera lens is connected with a signal input end of a non-refrigeration infrared focal plane array detector; the output end of the non-refrigeration infrared focal plane array detector is connected with the input end of an acquisition card; the output of the acquisition card is connected with an upper computer. By the aid of the electrical equipment fault diagnosis system, the current situation of the electrical equipment can be known in real time, fault reasons are found effectively and the future state of the equipment is predicated.

Description

technical field [0001] The invention relates to the field of electrical equipment fault diagnosis systems, in particular to an electrical equipment fault diagnosis system based on a thermal map analysis method. Background technique [0002] Whether the power equipment can work normally is directly related to the safe operation of the power system. With the emergence of ultra-high voltage, large units, and large power grids, the reliability requirements for power equipment are getting higher and higher. At present, most power users use low-voltage and high-current electrical equipment. Once the electrical equipment fails, it will easily cause high temperature. At the same time, poor contact of electrical equipment can cause high temperature, sparks, and arcs, which can easily become a source of ignition for fires. Such dangerous temperatures and hidden dangers are usually not easily found. [0003] Traditional temperature monitoring technology is affected by many factors, e...
