Description
Technical field
The present invention relates to a kind of magnetic core, more particularly to a kind of magnetic core for transformer structure.
Background technology
With the continuous development of China's economy, land resource increasingly lacks, and the floor space of transformer station is often subject to limit
System, its aerial bus inlet-outlet line direction can be also restricted.To coordinate transformer station to make somebody a mere figurehead the direction that walks of bus, it is often necessary to change
Become the orientation of bushing shell for transformer so that the direction one that walks of bus is maked somebody a mere figurehead in the orientation of bushing shell for transformer with transformer station
Cause.The orientation of bushing shell for transformer be typically fixed as it is transversely arranged, when need by the orientation of bushing shell for transformer for longitudinal direction
, it is necessary to sequence lead and by bushing shell for transformer longitudinal arrangement in inside transformer during arrangement.Not only inside transformer lead is complicated,
Connection is difficult, and bushing shell for transformer longitudinal arrangement is also needed to increase to the size of oil tank of transformer, has accordingly increased transformation body
Product, the dosage of oil, material, processing and the cost of transport of transformer so that transformer cost uprises.
Therefore, to solve the above problems, special provide a kind of new technical scheme.
The content of the invention
The present invention provides a kind of magnetic core for transformer structure.
The technical solution adopted by the present invention is：
A kind of magnetic core for transformer structure, including core body, the core body include pedestal, U-shaped magnetic core and I type magnetic
Core, U-shaped magnetic core and I the type magnetic core are separately mounted to the both ends of pedestal, groove is provided with the end face of the I types magnetic core, in I types
Coil is wound with magnetic core, through hole is provided with the I types magnetic core, the through hole is located at the top of coil, and is separated by one with groove
Segment distance, copper sheet is provided between U-shaped magnetic core and I the type magnetic core, groove is provided with the pedestal, the copper sheet is arranged on groove
It is interior.
Further, the I types magnetic core is made up of ferrite material.
Further, the width of the pedestal is more than the diameter of U-shaped magnetic core.
Further, the width of the pedestal is more than the diameter of I type magnetic cores.
The beneficial effects of the invention are as follows：It is simple in construction, it is safe to use, realize improved high current behaviour, high magnetic permeability and to temperature
The high patience changed, is made of ferrite so that the good wave filtering effect of magnetic core, combined using two kinds of magnetic poles, can
During making follow-up work, the magnetic line of force between transformer and inductance is independent, is independent of each other, improves the stability of work, through hole
Setting, improve the security of magnetic core, copper sheet can carry out disassembly and installation, meet the needs of different, vdiverse in function.
Brief description of the drawings
The present invention is described in further detail with reference to the accompanying drawings and detailed description.
Fig. 1 is the structural representation of the present invention.
Wherein：1st, core body, 2, pedestal, 3, U-shaped magnetic core, 4, I type magnetic cores, 5, groove, 6, copper sheet, 7, coil, 8, logical
