SwitchingPower Transformers

? Both transformer and transformer for power switching are of circuit type. But their winding or insulation type varies considerable according to the local or foreign safety standard, From the viewpoint of safety standard, it is necessary to provide the overheat protection system at the time of abnormality by taking into account the distance between the primary and secondary windings for proper insulation as well as the fire- retardant property and so fort ? The magnetic circuit connection may become electrically poor depending on the winding type which has a considerable influence on the power characteristics. ? This catalog describes the configuration of transformer normally used. In order to ensure appropriate design of the transformer, the following procedure should be strictly observed. ? (1) Transformer should be manufactured in accordance with the detailed transformer specification (2) Transformer should be manufactured pursuant to the transformer design prepared by us in accordance with the transformer design specification(transformer design data) (3) Transformer should be manufactured pursuant to the transformer and basic circuit designs prepared by us in accordance with the power specification.
