Component part, transformer framework is essential component part in transformer, it is provided for primary coil and secondary coil
The space of winding, while also playing a part of the silicon steel sheet in fixed transformer, transformer during prolonged use,
The temperature of coil windings will increase as time increases or the load of transformer is excessive and lead to the problem of overheat, therefore
The temperature of transformer would generally be monitored mounting temperature sensor on skeleton, existing transformer framework is generally divided into
Two kinds of structures, i.e. I-shaped structure and king's font structure.
Currently, application No. is the transformer bones that 201320454067.3 Chinese patent discloses a Seed King character form structure
Frame, it includes the baffle that two opposed ends around column are symmetricly set on around column, two pieces, setting around column outer ring and positioned at around column
Partition board and stitch seat, primary coil and secondary coil at center are separated rotating around on column and by partition board.A this system
Although king's font transformer framework skeleton steady ordered, simple in structure, when transformer starts inside will produce vortex shadow
The coil for ringing transformer itself, leads to coil itself heat production, causes temperature excessively high, and usually transformer is burned, and fire occurs, because
This designs a kind of transformer framework structure of anti-vortex.

Temperature is excessively high, it occur frequently that transformer is burned, phenomena such as leading to fire；
(2) existing transformer production installation process, occupies larger space, not only cannot easily store, but also can not
Easily installation and dismounting, cause great trouble；
(3) radiator that typically no addition assists in the anti-vortex device of existing transformer causes to be vortexed mutual inductance line
Circle temperature is excessively high, also results in the electromagnet damage of anti-vortex, further causes transformer itself and damages.
Invention content
In order to overcome the shortcomings of that prior art, the present invention provide a kind of transformer framework structure of anti-vortex, both solved
Traditional transformer of having determined is not provided with anti-vortex device, causes transformation coil because being vortexed self-induction itself heat production, causes temperature mistake
Height the problem of phenomena such as leading to fire, and solves the anti-vortex device of existing transformer only it occur frequently that transformer is burned
Using a shielding shell to shield external magnetic fields, but it is also difficult to become the self-induction vortex that transformation coil generates inside ballasting
To remove, this anti-anti- venturi effect of vortex device is poor, it is difficult to solve the problems, such as security risk, and also solve existing transformation
