Description

Technical field [0001] The invention relates to transformer detection equipment, in particular to a transformer detection device. Background technique [0002] Power transformers are important equipment for power transmission and distribution systems. With the development of power systems, the capacity and voltage levels of the power grid continue to increase. As the hub of electrical energy transmission, large-scale high-voltage transformers are especially important in the process of ultra-high-voltage long-distance power transmission. And Yu, its safe operation is directly related to whether the power system can work continuously and stably. Especially due to the complex structure and high cost of large-scale transformers, once a serious fault occurs and damaged, it will bring great difficulties to the maintenance work and cause major economic losses. In view of the importance of power transformers in the system, the protection of power transformers has always been valued and ...

AI Technical Summary

Problems solved by technology

Once a failure occurs, the power supply will be completely stopped, causing public safety problems and loss of personnel, equipment and property, and the repair time is much longer than other equipment

[0003] At present, in the detection process of power transformers, the detection of transformers still needs to adopt the shutdown detection method, and the detection of transformers needs to be tested out of the box, which requires a lot of manpower.
