Description

TECHNICAL FIELD

[0001] The present application relates to the field of infrared temperature measurement monitoring, and particularly relates to an online monitoring device for transformer infrared temperature measurement based on image recognition. BACKGROUND

[0002] A transformer is a device for changing AC voltage by using the principle of electromagnetic induction, and main components are a primary coil, a secondary coil and a core (magnetic core). Main functions are: voltage transformation, current transformation, impedance transformation, isolation, voltage stabilization (magnetic saturation transformer) and the like. Because a large amount of current passes through the transformer during operation, high-temperature combustion problems are prone to occur. In order to effectively monitor the temperature state of the transformer, a corresponding infrared camera can be arranged for image recognition, so that the transformer can be quickly reacted and processed when high-temperature combustion occurs.

[0003] Although the infrared camera can accurately identify the temperature state of the transformer, and when the transformer is combusted, the corresponding equipment controls the fire extinguishing device to spray foam and water to complete the fire extinguishing work. However, because the infrared camera is often arranged close to the transformer in order to accurately complete the temperature measurement work, the infrared camera will be damaged after the transformer is combusted at high temperature. This will cause unnecessary damage, and after the fire extinguishing device sprays foam and water, the infrared camera and other structures are also prone to damage. This will increase the damage of the user.

[0004] Therefore, the present application provides an online monitoring device for transformer infrared temperature measurement based on image recognition to solve the above problems. SUMMARY
