transformer excellenceing electric isolation

摘要

The present invention is characterized in that the primary winding of the transformer is constituted by one core and the iron core is vertically perpendicular to the winding so that the transformer for the instrument and the transformer are formed into a single article to reduce the size and weight, The present invention relates to a transformer and a current transformer excellent in electrical insulation by injecting an insulating layer under a constant temperature and constant pressure using a flame-retardant, non-combustible synthetic resin.;The present invention provides a transformer current transformer having excellent electrical insulation characteristics in which a fixing plate 6 is provided on the bottom of a bottom surface and two input and output terminals 11 and 12 are fixed on the upper surface of the transformer 4, The transformer iron core 43 is made of an iron core iron core and positioned in a direction perpendicular to the upper and lower sides. The terminal blocks 51 and 52 are molded and fixed left and right under the body 9, The neutral terminal 7 for grounding is attached to the lower side of the rear face of the current transformer and the partition 21 is formed between the upper end and the output terminal of the transformer and the cover 22 is covered with the bolt 23 It features a sealed box.;The present invention forms an insulating layer of a flame-retardant, non-flammable synthetic resin by a single molding method, thereby improving the electrical insulation of the device, and by forming the transformer for a meter and the transformer integrally therewith, The manufacturing cost can be reduced by reducing the material.
