Embodiment Construction

[0015] Embodiments of the present invention will be described below with reference to the drawings.

[0016] An iron core for a transformer according to an embodiment of the present invention is shown in FIG. 1 and FIG. 2 . It is constituted by inserting a winding coil 20 into an E-shaped iron core 10 and combining an I-shaped iron core 30 into the E-shaped iron core 10. . In addition, on the E-shaped iron core 10, two support grooves 11, 12 are respectively formed on the outer two ends of the contact portion with the I-shaped iron core 30, and two support grooves 11 and 12 are respectively formed on both sides of the I-shaped iron core 30. , 12 corresponding to the supporting protrusions 31,32. Therefore, the E-shaped iron core 10 and the I-shaped iron core 30 are formed by combining the support protrusions 31 , 32 with the support grooves 11 , 12 in a state where a plurality of them are evenly arranged. At this time, in order to prevent the support protrusions 31, 32 from ...

Abstract

Provided is an iron core for transformer arranging a plurality of E-type cores and I-type cores crimpingly jointed, accordingly it can obtain the manufacturing operations facilities without additional welding process and unitized process, prevent burning from the welding process, and reduce the core size without performance changing. The iron core consists of E-type core 10 and I-type core 30, on both ends of lateral of contact position in said E-type core 10 and I-type core 30 and both sides of said I-type core 10, forming two support slots 11, 12 and two support protrudes 31,32 corresponding to said support slots, to joint said support protrudes 31, 32 and said support slots 11,12 without no welding process, to prevent heat loss, without reducing performance to form said E-type cores 10 in the longitudinal and lateral direction only shorter 1 mm than the standard length, and to form I-type cores 30 in the lateral direction only shorter 1 mm than the standard length.

Description

technical field [0001] The present invention relates to an iron core for a transformer. Specifically, it relates to an iron core that can be manufactured by combining a plurality of E-shaped iron cores and I-shaped iron cores in a uniform arrangement without a welding process or a unitization process. Convenience, eliminating the burning loss that occurs in the welding process, and reducing the size of the iron core for transformers without performance changes. Background technique [0002] Generally, in the iron core for a transformer, a winding coil is inserted inside an E-shaped iron core, an I-shaped coil is welded and fixed to the E-shaped coil, and a bracket is welded and fixed to the E-shaped or I-shaped coil. In order to install it on other equipment, in this case, it is finished by dipping varnish for rust prevention of each iron core, suppression of magnetostrictive noise, moisture resistance of coil insulation seal, etc. However, since the iron core for the above...
