Description
A marine transformer is a type of electrical equipment used in ships. With the application of large-scale ships and electric propulsion, the occurrence rate of transformers in ship-electric systems has changed greatly. In recent years, ships using AC high-voltage power devices are increasing, and ship specifications generally recommend a nominal system voltage of 3-15 kV for ships AC high-voltage devices. Transformer cooling methods mainly include natural cooling or forced air cooling, oil immersion cooling and contact forced cooling.
