Description
Technical field
The utility model is related to the preposition anti-package glue insulation of the structure improved technology of transformer equipment, especially secondary coil to increase
Strong I-shaped skeleton transformer.
Background technology
Transformer is the device for changing alternating voltage using the principle of electromagnetic induction, and main member is primary coil, secondary
Grade coil and iron core or magnetic core.There are two transformer coils or more than two windings, wherein connecing the winding of power supply primary line
Circle, remaining winding is secondary coil.It can convert alternating voltage, electric current and impedance.Simplest iron-core transformer is by one
The coil of iron core that a soft magnetic materials is made and two numbers of turn being sleeved on iron core not etc. is formed, and the effect of iron core is to strengthen two
Magnetic coupling between coil.It is formed to reduce vortex and magnetic hystersis loss, iron core in iron by the silicon steel plate stacking painted；Two coils
Between there is no the contact of electricity, coil is coiled by insulated copper wire or aluminum steel.One coil connects AC power and is known as primary coil or original
Coil, another coil connect electrical appliance and are known as secondary coil or secondary coil.
The effect of transformer core adhesive tape wrapping maximum should be fastening iron core, improve closed assembly precision, seam is more preferable, so as to drop
Low iron loss and noise.The work of insulation perhaps can also be played certainly for special " adhesive plaster " of the transformer of small-sized low-voltage
With between iron core and coil, between iron core and ground.
Transformer is commonly used for buck/boost, matching impedance, security isolation etc. in electrical equipment and radio-circuit.Mainly
Function has：Voltage transformation, current transformation, impedance conversion, isolation, magnetic saturation transformer voltage stabilizing etc..Transformer core adhesive tape wrapping is most
Big act as fastening iron core, improves closed assembly precision, seam is more preferable, so as to reduce iron loss and noise.Certainly for small-sized low
The adhesive plaster of the transformer of voltage can also play the role of insulation between iron core and coil between iron core and ground.Become at present
Using automatic machine adhesive tape wrapping after the assembling of depressor magnetic core, due to mechanical oscillation or clipper with magnet core position error etc., magnetic can be generated
Core dislocation bad about 10%, off center operate so as to cause adhesive tape wrapping and generate dislocation, influence that inductance is unstable and appearance is not up to
To the standard requirement of dislocation≤0.2mm.
Winding including primary coil and secondary coil is the heart of transformer, is transformer transmission, converting electric power
Core.Winding insulation is reliably the basic guarantee of transformer long-term safety operation.For the winding insulation of high voltage transformer
Become particularly important.It not only directly affects the insulation performance of transformer, and due to the shared large percentage that insulate, to transformation
Technical performance, the economic indicator of device also have a great impact.Should be noted that when using coil not change arbitrarily coil shape,
Otherwise distance between size, direction and coil can influence the original inductance value of coil, should more be noted when particularly replacing high frequency coil
Meaning.
Utility model content
The purpose of this utility model, which is to provide the preposition anti-package glue insulation of secondary coil, enhances I-shaped skeleton transformer.
The purpose of this utility model will be realized by following technical measures：Including skeleton, insulating tape, primary coil,
Secondary coil and anti-package adhesive tape；Skeleton is in I-shaped, and first coiling primary coil is further around secondary coil processed on skeleton, in primary line
One group of insulating tape of outer laying is distinguished between circle and secondary coil and outside secondary coil, wherein, in secondary coil winding two
End is respectively coated by anti-package adhesive tape.
Especially, primary coil and secondary coil are coiled in the center pillar between opposite two notches of I-shaped skeleton on skeleton
On.
Especially, anti-package adhesive tape package secondary coil both ends of the surface outer rim at least two circle coils.
Especially, anti-package adhesive tape is more than its width in secondary coil medial surface in the width of secondary coil lateral surface.
Especially, the sum of width that anti-package adhesive tape coats at secondary coil lateral surface both ends is more than the 1/ of secondary coil width
2。
The advantages of the utility model and effect：The advance anti-package adhesive tape of secondary coil, adds dielectric strength, makes I-shaped
Skeleton can play the characteristics of winding area itself is big, can also reach the insulating requirements of king's font skeleton, kill two birds with one stone.It solves existing
It the problem of adhesive plaster dislocation caused by magnetic core dislocation existing for some transformer rubber coatings and unstable inductance, can realize to the magnetic that misplaces
The position adjustment of core, is properly positioned magnetic core reply, keeps the stability and accuracy of adhesive tape wrapping, reduce manual synchronizing intervention,
Improve transformer working performance.
