Tips: Working principle of step-down transformer
The step-down transformer is a transformer that converts the higher voltage at the input terminal into an ideal voltage with a relatively low output, so as to achieve the purpose of step-down. The step-down transformer is a very important equipment in the power transmission and transformation system. Its normal operation is not only related to its own safety and reliable power supply for users, but also directly affects the stability of the power system. The configuration of the step-down transformer protection should meet the requirement that the transformer should not be burned under any circumstances, which will expand the accident and affect the stability of the power system.
