Description
Technical field
The utility model is related to compensation capacitor technical field, more particularly to a kind of low-voltage dynamic reactive power adjuster.
Background technology
Low-voltage dynamic reactive power adjuster is a kind of electronic power devices that quick-switching can be carried out to power capacitor.It is existing
Adjuster includes mainly ontology, and accommodating chamber is equipped in the ontology, control circuit board is equipped in the accommodating chamber.
Since adjuster is power device, the control circuit board will produce a large amount of heat, existing adjuster
Radiator structure generally opens up heat emission hole in the cavity wall of the accommodating chamber, is then radiated to accommodating chamber by heat emission hole.
But such radiator structure, external dust are easy to enter in accommodating chamber from heat emission hole, therefore, lead to have ash in accommodating chamber
Dirt is accumulated, to damage the precision element in control circuit board.
Utility model content
The purpose of this utility model is：Dust accumulation and the good low pressure dynamic regulation of heat dissipation can be prevented by providing one kind
Device.
The solution that the utility model solves its technical problem is：A kind of low-voltage dynamic reactive power adjuster, including ontology,
It is equipped with accommodating chamber in the ontology, control circuit board is installed, the lower cavity wall of the accommodating chamber is metal material in the accommodating chamber
The bottom plate of matter, the bottom plate are equipped with the column of several metal materials, and the control circuit board horizontal is described on the column
The lower section of bottom plate is equipped with the ventilation shaft parallel with the bottom plate, the upper tube wall of the ventilation shaft and the bottom plate one at
The air inlet of type, the ventilation shaft is equipped with fan.
Further, the downside of the bottom plate is equipped with several cooling fins towards the ventilation shaft.
Further, the cooling fin, column, bottom plate are integrally formed.
The utility model has the beneficial effects that：The adjuster of the structure utilizes the heat transfer of column and bottom plate, the row of fan
Heat so that the cavity wall of accommodating chamber can realize natural heat dissipation without opening up heat emission hole, avoid dust and entered by heat emission hole
The accommodating chamber avoids dust accumulation and damages adjuster.The adjuster can be widely used for electric power network system.
Description of the drawings
It is required in being described below to embodiment in order to illustrate more clearly of the technical scheme in the embodiment of the utility model
Attached drawing to be used is briefly described.Obviously, described attached drawing is a part of the embodiment of the utility model, rather than complete
Portion's embodiment, those skilled in the art without creative efforts, can also be obtained according to these attached drawings it
His design scheme and attached drawing.
Fig. 1 is the structural schematic diagram of adjuster.
Specific implementation mode
The technique effect of the design of the utility model, concrete structure and generation is carried out below with reference to embodiment and attached drawing
It clearly and completely describes, to be completely understood by the purpose of this utility model, feature and effect.Obviously, described embodiment
It is a part of the embodiment of the utility model, rather than whole embodiments, it is based on the embodiments of the present invention, the skill of this field
The other embodiment that art personnel are obtained without creative efforts belongs to the model of the utility model protection
It encloses.In addition, all connection/connection relations being previously mentioned in text, not singly refer to component and directly connect, and referring to can be according to specific reality
Situation is applied, by adding or reducing couple auxiliary, to form more preferably coupling structure.Each technology in the invention is special
Sign, can be with combination of interactions under the premise of not conflicting conflict.
Embodiment 1, with reference to figure 1, a kind of low-voltage dynamic reactive power adjuster, including ontology, the ontology is interior to be equipped with accommodating chamber
1, control circuit board 2 is installed, the lower cavity wall of the accommodating chamber 1 is the bottom plate 3 of metal material, the bottom in the accommodating chamber 1
Plate 3 is equipped with the column 31 of several metal materials, and 2 horizontal of the control circuit board is on the column 31, under the bottom plate 3
Side is equipped with the ventilation shaft 4 parallel with the bottom plate 3, and the upper tube wall of the ventilation shaft 4 is integrally formed with the bottom plate 3, institute
The air inlet for stating ventilation shaft 4 is equipped with fan 5.
When the adjuster radiates, the column 31 is by the heat transfer in control circuit board 2 to the bottom plate 3, wind
Fan 5 is opened so that and air such as Fig. 1 upward arrows direction on ventilation shaft 4 is flowed, and is contacted with the bottom plate 3 by moving air,
The heat on bottom plate 3 is taken away, to realize the heat dissipation to control circuit board 2.The adjuster of the structure utilizes column 31 and bottom plate
3 heat transfer, the heat extraction of fan 5 so that the cavity wall of accommodating chamber 1 can realize natural heat dissipation without opening up heat emission hole, avoid
Dust enters the accommodating chamber 1 by heat emission hole, avoids dust accumulation and damages adjuster.The adjuster can be widely used for electricity
Power network system.
As an optimization, the downside of the bottom plate 3 is equipped with several cooling fins 32 towards the ventilation shaft 4.Using dissipate
Backing 32 improves heat dissipation effect.
As an optimization, the cooling fin 32, column 31, bottom plate 3 are integrally formed.The heat dissipation effect for improving adjuster, avoids
Cooling fin 32, column 31, bottom plate 3 cause coefficient of heat transfer to reduce because of welding.
The better embodiment of the utility model is illustrated above, but the invention be not limited to it is described
Embodiment, those skilled in the art can also make various equivalent changes without departing from the spirit of the present invention
Type or replacement, these equivalent modifications or replacement are all contained in the application claim limited range.
