Title:
STABILITY TRANSFORMER MAGNETIC CORE
Document Type and Number:
WIPO Patent Application WO/2019/006879
Kind Code:
A1
Abstract:
A stability transformer magnetic core, comprising a magnetic core body (1); the magnetic core body comprises a base (2), a U-shaped magnetic core (3), and an I-shaped magnetic core (4); the U-shaped magnetic core and the I-shaped magnetic core are respectively mounted at both ends of the base; a groove (5) is formed on an end face of the I-shaped magnetic core, a coil (7) is wound on the U-shaped magnetic core, a through hole (8) is formed on the U-shaped magnetic core, and the through hole is provided oppositely to the coil; a copper sheet (6) is provided between the U-shaped magnetic core and the I-shaped magnetic core, a slot (9) is formed on the base, and the copper sheet is mounted in the slot. The transformer magnetic core is simple in structure and safe in use, achieving a high current characteristic, a high magnetic conductivity, and a high tolerance for temperature change; the transformer magnetic core is made of ferrite so that the filtering effect of the magnetic core is good, and two magnetic columns are combined so that a magnetic line of force between the transformer and an inductor are independent of each other in the subsequent working process without affecting each other, improving the stability of working; the setting of the through hole improves the safety of the magnetic core; and the copper sheet can be detached and mounted to meet different needs, and thus the functions are various.
