JPS55143011A - Transporting and assembling method of stationary inductor device - Google Patents

Abstract

PURPOSE:To prevent moisture absorption of winding in a static inductor device and eliminate necessity of redrying process of the winding of a transformer by storing the wire winding within a container, while only the magnetic legs of iron core are passed through the container, and detaching only the iron core when transporting a transformer whose yoke is located out of the container, transporting it separately and then assempling them in the field. CONSTITUTION:A winding 1 wound with copper wires and insulator paper is accommodated in a container 2 made of thermoplastic resin having a through hole for passing magnetic legs of an iron core 4 and cover 3. Then, silicon steel sheet laminate iron core 4 is brought into close contact with the outside of the container while inserting the magnetic legs into the hole, an outer box 5 is mounted on the lower end of the core 4, and a cooling insulating oil is filled in the container 2 by utilizing the cover 3 to form a transformer 10. When the transformer 10 is thus assembled and transported to a field, only the iron core 4 is pulled out of the transformer, but the winding 1 is retained in oil. After the transformer is transported to the field with such configuration, it is unnecessary to redry or retest the transformer at the field.
