Description
Technical field
The present invention relates to a kind of in natural air cooled operating condition decline low noise and improves the structure of encapsulating coil heat-sinking capability.
Background technique
Influence of the dry-type air-core reactor vulnerable to external environmental factor, especially rainwater in actual moving process, when
Rainwater will significantly reduce the resistance to voltage levels of reactor when pouring reactor encapsulating coil surface, jeopardize the normal operation of reactor, lead to
Reduce the influence of environmental factor frequently with rain shade is installed additional on reactor top；Simultaneously in the hollow core of actual moving process
Device generates biggish noise, in order to reduce influence of the noise to ambient enviroment, usually on the outside of the outermost encapsulating coil of reactor around
The empty encapsulating coil of system is as blimp.Patent 201320643492.7 discloses dry-type air-core reactor rain-proof grid, patent
201320825965.5 disclose a kind of dry reactor rain cover, reduce environment by installing rain shade additional in reactor end
Influence of the factor to reactor；Patent 201721246283 discloses a kind of noise reduction for reducing dry reactor operation noise
Device.The above method can only it is one-side improve reactor heat dissipation performance or reduce noise, if in practice reactor install additional
Rain shade structural parameters and blimp structural parameters will cause each encapsulating coil heat, heat dissipation inside reactor with reasonable
Capacity variance is larger, and coil temperature rise is encapsulated in part can exceed that the temperature rise of hot spot of reactor, influences the peace of reactor in systems
Complete and stable operation.
Summary of the invention
In view of the drawbacks of the prior art, the invention proposes one kind in natural air cooled operating condition decline low noise and to improve encapsulating
The structure of coil heat-sinking capability.It can be improved the radiating efficiency of reactor, and the effectively packet of control reactor in actual operation
Coil temperature rise and noise level are sealed, has the characteristics that simple structure, good heat dissipation effect and low noise.
To solve the above-mentioned problems, the invention solves technical solution are as follows:
A kind of structure in natural air cooled operating condition decline low noise and raising encapsulating coil heat-sinking capability, including blimp, double screenings
Awning and multiple reactors, in blimp upper end, each reactor is arranged in blimp for double rain shade settings, and reactor includes same
The multi-turn of axis setting encapsulates coil, and each coil of encapsulating electrically is being connected in parallel, and is equipped between two adjacent rings encapsulating coil a plurality of
Stay, reactor upper and lower ends are connect with two starframes respectively.
Double rain shades include rain shade under rain shade and taper in taper, pass through more between upper rain shade and lower rain shade
Support rod connection.
Blimp upper and lower ends are equipped with through-hole, and the stickup of blimp inner wall is fixed with sound-proof material.
Technical effect of the invention are as follows: the present invention mainly carries out optimization from reactor, rain shade and blimp etc. and sets
Meter, on the one hand can be realized between reactor respectively encapsulates coil has essentially identical heat, heat-sinking capability, encapsulating coil temperature rise point
Cloth is essentially identical, reduces reactor temperature rise of hot spot, improves the radiating efficiency of reactor；On the other hand electricity can be significantly reduced
Noise level of the anti-device in actual motion reduces influence of the reactor noise to ambient enviroment., heat dissipation simple with structure
The characteristics of effect is good and low noise.
Detailed description of the invention
Following further describes the present invention with reference to the drawings:
Fig. 1 is the schematic diagram of the section structure of the invention,
Fig. 2 is the schematic diagram of the section structure of the invention.
In figure: double rain shades 1, multiple reactors 3, upper rain shade 11, lower rain shade 12, sound-proof material 21, lead to blimp 2
Hole 22, encapsulating coil 31, starframe 32, stay 33.
Specific embodiment
As illustrated in fig. 1 and 2, a kind of knot in natural air cooled operating condition decline low noise and raising encapsulating coil heat-sinking capability
Structure, including blimp 2, double rain shades 1 and multiple reactors 3, in 2 upper end of blimp, each reactor 3 is arranged for double rain shade settings
In blimp 2, reactor 3 includes that the multi-turn of coaxial arrangement encapsulates coil 31, and each coil 31 of encapsulating electrically is being connected in parallel,
Two adjacent rings are encapsulated and are equipped with a plurality of stay 33 between coil 31, and encapsulating coil 31 is followed successively by metallic conductor, insulation material from inside to outside
Material and epoxy glass fiber, stay 33 are radially arranged along 31 air flues of encapsulating coil, 3 upper and lower ends of reactor respectively with two
Starframe 32 connects, and starframe 32 plays the role of accurately distributing encapsulating 31 electric current of coil and reinforces reactor 3.
Double rain shades 1 include rain shade 12 under rain shade 11 and taper in taper, upper rain shade 11 and lower rain shade 12 it
Between pass through the connection of more support rods.Reactor 3 is encapsulated after the heat that coil 31 distributes heats the air of surrounding and is climbed sharply upwards, is passed through
Two rain shade intermediate spaces are crossed outwardly to disperse, at the same double rain shades 1 can prevent upper layer sunlight direct irradiation after heat is passed
Lower layer is passed, the excessively high influence heat-conducting effect of lower layer's temperature is avoided, can be guaranteed good by the hot-air of rain shade centre bore
It flows through among rain shade, carries out heat convection with extraneous large space.
2 upper and lower ends of blimp are equipped with through-hole 22, and through-hole 22 can enter in blimp 2 very well convenient for outside air,
The air formation heat convection that reactor 3 encapsulates coil 31 and 2 bottom end of blimp enters, improves the heat-sinking capability of reactor 3, every
2 inner wall of sound cover is pasted with sound-proof material 21.On the one hand, the rain shade of this kind of structure can be good at that rainwater is stopped to enter reactor 3
Outside encapsulate coil 31, reduce due to the influence of rainwater cause reactor 3 encapsulate coil 31 insulation damage；On the other hand, energy
The noise generated in 3 operational process of reactor is enough effectively reduced, and structure is simple.
