technical field

The invention relates to the technical field of transformers, in particular to a transformer vibration detection system and detection method.

Background technique

A transformer is a device that uses the principle of electromagnetic induction to change the AC voltage. The main components are a primary coil, a secondary coil and an iron core (magnetic core). In electrical equipment and wireless circuits, it is often used for raising and lowering voltage, matching impedance, safety isolation, etc. In a generator, whether the coil moves through a magnetic field or the magnetic field moves through a stationary coil, an electric potential is induced in the coil. In both cases, the value of the magnetic flux remains unchanged, but the amount of magnetic flux intersecting with the coil changes, which is the principle of mutual induction. A transformer is a device that uses electromagnetic mutual induction to transform voltage, current, and impedance.

step two: opening the connecting device (4) to enable the connecting device (4) to wrap a telegraph pole, fixing and locking the whole equipment, and simultaneously opening the fixing device (2) to install the transformer in the fixing device (2);

step three: the transformer is wrapped and fixed by the fixing device (2), the detecting device (1) is arranged at the top of the transformer and used for vibration detection, and the vibration amplitude is detected by detecting the current and the reflection of light in the detecting device (1) during vibration.
