Description

technical field [0001] The invention relates to the technical field of transformers, in particular to a transformer overload protection mechanism and an overload protection method. Background technique [0002] The transformer is a device that uses the principle of electromagnetic induction to change the AC voltage. The main components are the primary coil, the secondary coil and the iron core (magnetic core). The main functions are: voltage conversion, current conversion, impedance conversion, isolation, voltage stabilization (magnetic Saturated transformer), etc., in the process of installing the transformer on the line, in order to protect the safety of the equipment and the line, an overload protection device is usually installed to prevent the main power line from being overheated and damaged due to overload. There are following problems at prior art: [0003] 1. There are many electrons inside the overload protection mechanism, which will easily lead to excessive accu...
