Description

technical field [0001] The invention belongs to the technical field of detection equipment, and in particular relates to a non-destructive detection device for windings in a transformer cavity and a control method thereof. Background technique [0002] A transformer is a device that uses electromagnetic induction to change the AC voltage. It is composed of primary coils, secondary coils and iron cores. Its main functions include voltage, current, impedance transformation, isolation, and voltage stabilization. In a power system, a transformer is necessary. Transformers need periodic power outage inspections, checking the working status of firmware and fault diagnosis. It is necessary to arrange professional staff to enter the transformer through the manhole of the transformer or open the transformer for inspection and maintenance. This detection method not only has a very high maintenance cost, but also brings pollutants into the transformer, which is also a hidden danger to...

AI Technical Summary

Problems solved by technology

[0004] To sum up, the traditional detection method uses an indirect method to obtain the basis for the damage of the internal coil of the transformer. However, this method has inaccurate coil fault location and is easy to misjudge, resulting in delays in maintenance time and increased maintenance costs.
