Abstract
A method for insulating packing a transformer comprises the steps of combining a content of a transformer to a plurality of pins by leads; placing the content into a platform of a lower mold and fixing the pins by fixtures; sealing an upper mold to the lower mold and exposing parts of the pins; and filling insulating material into a space formed by the upper mold and the lower mold. The platform of the lower mold is at a top of the lower mold having a maximum area. When releasing the upper mold and the lower mold, the insulating material will enclose the iron core, coil, leads and pins so as to form an insulating casing. A part of the iron core is hollowed and then a lower density insulating glue is applied to the hollowed portion of the insulating casing.
Claims4
A method for packing a transformer comprising the steps:
- using leads to combin a content of a transformer to a plurality of pins;
- placing the content into a platform of a lower mold and fixing the pins by fixtures;
- sealing an upper mold to the lower mold and exposing parts of the pins;
- and
- filling insulating material into a space formed by the upper mold and the lower mold;
- wherein the platform of the lower mold is located at a top of the lower mold which has a maximum area, the platform protrudes into the space formed by the upper mold and the lower mold for placing the content;
- when releasing the upper mold and the lower mold, the insulating material will enclose the content;
- leads and pins so as to form an insulating casing;
- a part of the iron core is hollowed so that the iron core and coil expose out;
- and lower density insulating glue is applied to the hollowed portion of the insulating casing;
- the density of the insulating glue is lower than that of the insulating casing;
- since the density of the insulating glue is low, it has the effect of ventilation.
A packing structure for insulating a transformer comprising;
- a layer of insulating casing enclosing the transformer;
- a lower insulating glue applied to the hollowed portion of the insulating casing;
- the density of the insulating glue is lower than that of the insulating casing;
- since the density of the insulating glue is low, it has the effect of ventilation.
