Description
Technical field
The utility model belongs to technical field of electric power, relates to a kind of frequency converter.
Background technology
Frequency converter is application converter technique and microelectric technique, controls the electric control appliance of alternating current motor by changing machine operation supply frequency mode.Frequency converter is primarily of the composition such as rectification (AC-DC), filtering, inversion (direct current becomes interchange), brake unit, driver element, detecting unit microprocessing unit.Frequency converter close to the inner portion IGBT cut-off the voltage and the frequency that adjust out-put supply; there is provided the supply voltage required for it according to the actual needs of motor, so reach energy-conservation, the object of speed governing, in addition; frequency converter also has a lot of defencive functions, as overcurrent, overvoltage, overload protection etc.Along with improving constantly of industrial automatization, frequency converter have also been obtained application widely.
In order to increase radiating effect, frequency converter can be arranged fin and many louvres can be offered in side, be convenient to dispel the heat to the electronic component of frequency converter inside, because the application of frequency converter is very extensive, therefore its operational environment is also quite complicated, and in the occasion that some are special, sometimes dust can be larger, so because the louvre on general frequency converter is not closable, so outside dust will enter into frequency converter inside by louvre.In addition, even when frequency converter does not work, this louvre is also open, and so this also can increase the dust inlet of frequency converter to a certain extent.
Utility model content
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of frequency converter, can be sealed up by louvre when external dust is larger or when not working, to reach good dust-proof effect.
For achieving the above object, the utility model provides following technical scheme:
A kind of frequency converter, comprise the housing that inside is provided with electronic devices and components, housing is provided with heat-conducting seat, and heat-conducting seat is provided with some fin, fin is provided with radiator fan, the side of described housing is provided with louvre, described heat-conducting seat is provided with metallic plate, and described metallic plate comprises fixed part and movable part, and described fixed part is fixedly connected with described heat-conducting seat, described movable part and described fixed part hinged, described movable part can to the upset of described louvre side.
By adopting technique scheme, movable part on sheet metal can overturn to louvre side, so, when the operational environment dust of frequency converter is larger or when not working when frequency converter, just can by overturning this movable part thus louvre being covered, this makes it possible to effectively prevent dust from entering into frequency converter inside, to play good dust-proof effect.
Further, described fixed part is provided with that the sidewall of groove described in the groove that coordinates with described movable part is added is provided with a fixed axis, described movable part one end is provided with the through hole coordinated with described fixed axis, and described movable part is set on described fixed axis by described through hole.
Further, described housing is provided with pit bit, and described louvre is arranged in described pit bit, and described pit bit coordinates with described movable part.
Further, described movable part is provided with the fixture block coordinated with described louvre.
Further, described fixture block is made up of elastomeric material.
Compared with prior art, the utility model is provided with sheet metal on heat-conducting seat, and this sheet metal comprises a turnover movable part, and this movable part can be covered close for the louvre on the housing of frequency converter by upset.So, if there is larger dust in the operational environment of frequency converter, just louvre can have been covered by the above-mentioned movable part of Selection utilization, so dust-proof; When frequency converter does not work, above-mentioned movable part also can be utilized to cover louvre, reach effective dust-proof object.

Embodiment
Referring to figs. 1 through Fig. 6, the utility model embodiment is described further.
A kind of frequency converter, comprise the housing 1 that inside is provided with electronic devices and components, housing 1 is provided with heat-conducting seat 2, and heat-conducting seat 2 is provided with some fin 21, fin 21 is provided with radiator fan 3, the side of housing 1 is provided with louvre 11, heat-conducting seat 2 is provided with metallic plate 22, and metallic plate 22 comprises fixed part 221 and movable part 222, and fixed part 221 is fixedly connected with heat-conducting seat 2, movable part 222 is hinged with fixed part 221, and movable part 222 can overturn to louvre 11 side.
In the present embodiment, as shown in Figure 5 and Figure 6, fixed part 221 is provided with the groove coordinated with movable part 222 to the concrete structure of sheet metal, specifically groove is equal with the width of movable part 222, so, movable part 222 just can tightly be stuck in groove, can not rock.
The operation principle of the present embodiment:
As can see from Figure 2, the movable part 222 on sheet metal can overturn to louvre 11 side, so, when frequency converter is idle time, the louvre 11 that movable part 222 can be turned over seals, and to prevent dust from entering into frequency converter inside, thus plays good dust-proof effect.In addition, because movable part 222 itself is also metal, even if sealed up by louvre 11, certain radiating effect is so also had.
In the present embodiment, movable part 222 with the connected mode of fixed part 221 is, fixed part 221 is provided with that the sidewall of the groove groove coordinated with movable part 222 is added is provided with a fixed axis 2211, movable part 222 one end is provided with the through hole 2222 coordinated with fixed axis 2211, and movable part 222 is set on fixed axis 2211 by through hole 2222.
Further, housing 1 is provided with pit bit 12, and louvre 11 is arranged in pit bit 12, and pit bit 12 coordinates with movable part 222.Specifically the size of pit bit 12 is identical with the size of movable part 222, and so, movable part 222 can tightly be stuck in pit bit 12 when turning and covering on louvre 11.
Further, movable part 222 is provided with the fixture block 2221 coordinated with louvre 11.When movable part 222 turn seal on louvre 11 time, the fixture block 2221 be arranged on movable part 222 just can be embedded in louvre 11.This is because after movable part 222 has overturn often, so housing 1 just likely can have been worn and torn by movable part 222, just likely there will be loosening when so movable part 222 covers on louvre 11.By adopting above-mentioned setting, just can ensure that movable part 222 covers firmly on louvre 11 can not be movable.
In addition, the above-mentioned fixture block 2221 mentioned is made up of elastomeric material.Here, this elastomeric material can be rubber.Because if fixture block 2221 does not have elasticity, that just must be configured to coordinate very much with the shape of louvre 11, that like this, fixture block 2221, when being embedded in louvre 11, will inevitably cause wearing and tearing to the housing 1 of frequency converter, therefore, if fixture block 2221 has certain elasticity, so when fixture block 2221 is embedded in louvre 11, just can reach fixture block 2221 object be stuck in louvre 11 tightly by deformation, thus can the generation that above-mentioned situation be prevented much of that.
