The size of power, depending on the material and cross-sectional area of iron core.The effect of iron core is to strengthen the magnetic coupling between two coils.In order to
Vortex and magnetic hystersis loss in iron are reduced, iron core is formed by the silicon steel plate stacking painted;There is no the contact of electricity between two coils;Line
Circle is coiled into by insulated copper wire (or aluminum steel).One coil connects AC power and is referred to as primary coil (or primary coil), another coil
Connect electrical appliance and be referred to as secondary coil (or secondary coil).Actual transformer is very complicated, is inevitably present copper loss (coil
Resistance heating), iron loss (iron core heating) and leakage field (line of magnetic induction closed through air) etc..
At present, existing anti-interference transformer core is also without the efficient jamproof function of comprehensively realization;And the change having
The screening arrangement structure that depressor iron core is used is complex, is unfavorable for popularization and application.
Utility model content
1. the technical problem to be solved

Efficiently jamproof purpose, and the screening arrangement used is simple in construction is comprehensively realized, implements simple, it is easy to utilize.
2. technical scheme
To solve the above problems, the utility model is adopted the following technical scheme that:
A kind of effective anti-interference transformer core, including overlap be " mouth " font upper core and lower core,
Be arranged with armature winding and secondary windings on the overlapping side of the upper core and lower core, the armature winding and secondary windings it
Between and both sides be equipped between shielded partitions, and adjacent two shielded partitions provided with shrouding respectively above and below armature winding and secondary windings
The shielding in portion is additionally provided with radome around part on the outside of the upper core and lower core.
Specifically, the upper core and lower core by two c-type silicon steel sheet groups into.C-type silicon steel sheet part is seldom, general
Property it is strong, production efficiency is high.Upper and lower iron core is constituted with C-type steel piece, the production stage of iron core is simplified.
Specifically, the shielded partitions are iron plate.Iron plate can absorb certain magnetic energy, weakens magnetic disturbance.
Specifically, it is described to shield on part around the alternate copper foil of interlayer.Vortex can produce one caused by layers of copper
The magnetic field opposite with interference magnetic field, to offset magnetic disturbance.
Specifically, the radome is the box shaped object for the sandwich construction being made up of soft iron plate and copper coin.On the one hand utilize
Its characteristic carries out magnet short-cut path, on the other hand offsets magnetic disturbance by caused vortex in layers of copper, therefore can greatly reduce transformation
Leak in the magnetic field of device.
Further, the radome includes inside and outside two layers of tinplate and the copper coin between inside and outside two layers.It is inside and outside
Layer uses iron plate, plays magnetic screen;Electrostatic screen can be played after centre copper, ground connection.
Further, the shielded partitions are connected with radome, and are grounded.This structure is mainly used to filter common mode disturbances.
3. beneficial effect
(1) the utility model include overlap be " mouth " font upper core and lower core, armature winding and time
Level winding is on the overlapping side of two iron cores, and the iron core matrix is similar in ED iron cores, application process, the overlapping side of two iron cores
The magnetic flux of interior generation each leads to upper and lower side, makes there is also magnetic circuit outside two windings, therefore leakage field is small, small to overall interference.
(2) the utility model by add screen layer, around copper foil shielding around part and radome, further control
Leakage field, can also filter high frequency differential mode interference, and the interference that isolation common mode inhibition is produced prevents external electromagnetic field by transformer to electricity
Road forms interference, and efficiently jamproof purpose is realized from multi-level.
(3) screening arrangement that the utility model is used is simple in construction, specifically on armature winding and secondary windings
Shielding is additionally provided with the outside of bottom around part, its is ingenious in design, while not influenceing winding to wind, after upper copper foil, is formed
Screen layer to surrounding winding, realizes primary overall anti-interference function.
The utility model is multi-level, comprehensively realize efficiently jamproof purpose, and the screening arrangement structure letter used
It is single, implement simple, it is easy to utilize.
