Description
Technical field
The invention belongs to field transformers more particularly to one kind can cooling-down type high frequency transformer.
Background technique
High frequency pressure swing techniques are had been widely used, but due to the limitation of the material of high frequency transformer and manufacture craft,
So that the distribution parameter of high frequency transformer capacitor, inductance is big, loss is big, especially leakage inductance is big, export at low voltage electric current by
To limitation, the output power of transformer can not be improved.At the same time, transformer loss is excessive, and high frequency transformer heat dissipation is difficult, with
The increase of output power, the calorific value of transformer is big, and temperature rise is very high, and transformer normal temperature is at 60~70 degree or so.
Rainy day air velocity is slow, and high frequency transformer heat dissipation is affected, and easy temperature is excessively high, causes fire.Therefore it needs
Want a kind of high frequency transformer for reinforcing heat dissipation in the rainy day.
Summary of the invention
The purpose of the present invention is to provide a kind of high frequency transformers, can reinforce heat sinking function in rainy day high temperature.
In order to achieve the above object, base case of the invention provides a kind of high frequency transformer, including high frequency transformer sheet

On cabinet.
The principle of this base case is: when raining, rainwater, which enters, connects rain slot, and is entered in transformer tank body by water inlet pipe
Accommodating chamber in.When transformer temperature increases, the induction cylinder for being adjacent to transformer is increased.Incude the titanium dioxide in cylinder
Nitrogen accelerates gasification, makes to incude the air pressure liter in cylinder, stretches out the piston rod for incuding cylinder.Incude close on the piston rod of cylinder
Sealing plate enters seal groove, and then the duct occlusion that will intake.Rainwater in accommodating chamber accelerates volatilization because the temperature of transformer increases, and holds
The indoor air pressure of chamber of receiving increases, and since water inlet pipe has been closed, air pressure pushes the piston rod movement of pusher cylinder, pusher cylinder
Piston rod on promotion rack drives rotate gear rotation, rotate gear rotate when, rotation axis rotates with it, rotation axis rotation
When radiator shutter work, radiate to transformer-cabinet, complete at this time the rainy day enhancing heat sinking function process.
When transformer operation irregularity temperature, which rapidly rises, causes insulating materials burning on fire, the air pressure of accommodating chamber is rapidly
Increase, so that the piston rod of pusher cylinder is shifted bottom onto rapidly, cannot move.At this point, excessively high air pressure makes to seal film rupture, gas
Pressure pushes the piston rod for cylinder of preventing fires, so that the sliding wall of dry ice chest be made to open, dry ice falls on transformer under dry ice chest
On, it puts out a fire to transformer.
The beneficial effect of this base case is: 1. present apparatus can dissipate transformer using rainwater enhancing when rainy
Heat enhances the heat sinking function of rainy day transformer.
2. the present apparatus can carry out automatically fire extinguishing processing to transformer when the rainy day is on fire.
Prioritization scheme one: the transformer-cabinet peripheral wall is equipped with several cooling holes.The setting of cooling holes passes through natural wind,
Transformer is cooled down.
Prioritization scheme two: the radiator shutter is obliquely installed, and dry ice chest dissipates between radiator shutter and transformer-cabinet
The cold air around dry ice chest is blowed into transformer-cabinet when hot blade rotates.Radiator acts on the cold sky around dry ice chest
Cold air is blowed to transformer by gas, keeps cooling effect stronger.
Prioritization scheme three: the bottom plate of the dry ice chest is obliquely installed to transformer-cabinet.Inclined bottom plate makes dry ice faster
Fall on transformer.
Prioritization scheme four: the dry ice chest bottom is equipped with through-hole, is fixed on through-hole across cylinder, rotation axis is rotatably connected on
In cylinder.It is fully located at dry ice chest in the sphere of action of radiator shutter, further increases cooling effect.
Prioritization scheme five: the transformer-cabinet, induction cylinder, pusher cylinder and fire prevention cylinder are made of copper.Copper
Thermal conductivity is high, keeps the effect of the present apparatus more prominent.
