Description
Technical field
The utility model relates to a kind of electrical equipment, particularly a kind of frequency converter.
Background technology
Frequency converter is one of modern electrical machine speed regulating control and energy-conservation indispensable important devices, industrial circle application widely.Main circuit of converter is made up of rectification circuit, intermediate circuit, inverter circuit three part, and the power device caloric value in the course of the work in these circuit is comparatively large, and the housing of therefore frequency converter is generally all provided with ventilating heat dissipating hole.
Frequency converter is generally mounted near the working site of motor simultaneously, if in rainy day work, the steam in air easily enters in frequency converter shell with cooling air, causes frequency converter to damage.
Utility model content
In view of this, the purpose of this utility model is to provide a kind of frequency converter with water-proof function, to solve existing frequency converter easily by the problem that steam damages.
The utility model has the frequency converter of water-proof function, comprise housing, the base plate of described housing there is air inlet, the top board of described housing has been arranged on air outlet, aerofoil fan is provided with in described air outlet, described housing also comprises the square tubulose skirtboard being positioned at below base plate, upper spacer and lower clapboard is provided with in described skirtboard, described upper spacer is provided with and somely stretches out downwards, and the upper spoiler of arranged concentric, described lower clapboard is provided with some protruding upward, and the lower spoiler of arranged concentric, described upper spoiler and lower spoiler interlaced arrangement, skirtboard between described upper spacer and lower clapboard circumferentially there are some air admission holes, described upper spacer is provided with venthole, described venthole is positioned at the upper spoiler of innermost layer.
Further, described skirtboard inwall is provided with bearing rib, and described upper spacer and lower clapboard are all bolted on bearing rib.
Further, described lower clapboard is the taper shape that the high edge in middle part is low, and the bottom of described lower spoiler is provided with water hole, and the edge of described lower clapboard is provided with apopore.
The beneficial effects of the utility model:
The utility model has the frequency converter of water-proof function, it by arranging the upper spoiler of interlaced layout and lower spoiler in the square tubulose skirtboard of frequency converter shell bottom, air-flow is made to become U-shaped circuitous flow between upper and lower spoiler, spoiler with airflow collision process in the carbonated drink entrained by air-flow is retained down, realize gas-water separation, and then avoid steam to enter in frequency converter shell causing damage to electric elements, frequency converter failure rate can be reduced, extend frequency converter useful life.
Accompanying drawing explanation
Fig. 1 is the sectional structure schematic diagram that the utility model has the frequency converter of water-proof function.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further described.
As shown in the figure, the present embodiment has the frequency converter of water-proof function, comprise housing 1, the base plate of described housing there is air inlet 2, the top board of described housing is arranged on air outlet 3, aerofoil fan 4 is provided with in described air outlet, described housing also comprises the square tubulose skirtboard 5 being positioned at below base plate, upper spacer 6 and lower clapboard 7 is provided with in described skirtboard, described upper spacer is provided with and somely stretches out downwards, and the upper spoiler 8 of arranged concentric, described lower clapboard is provided with some protruding upward, and the lower spoiler 9 of arranged concentric, described upper spoiler and lower spoiler interlaced arrangement, skirtboard between described upper spacer and lower clapboard circumferentially there are some air admission holes 10, described upper spacer is provided with venthole 11, described venthole is positioned at the upper spoiler of innermost layer.
The present embodiment has the frequency converter of water-proof function, it by arranging the upper spoiler of interlaced layout and lower spoiler in the square tubulose skirtboard of frequency converter shell bottom, air-flow is made to become U-shaped circuitous flow between upper and lower spoiler, spoiler with airflow collision process in the carbonated drink entrained by air-flow is retained down, realize gas-water separation, and then avoid steam to enter in frequency converter shell causing damage to electric elements, frequency converter failure rate can be reduced, extend frequency converter useful life.
As the improvement to the present embodiment, described skirtboard inwall is provided with bearing rib 12, and described upper spacer and lower clapboard are all fixed on bearing rib by bolt 13, the easy accessibility of upper spacer and lower clapboard, are convenient to safeguard.
As the improvement to the present embodiment, described lower clapboard is the taper shape that the high edge in middle part is low, the bottom of described lower spoiler is provided with water hole 14, the edge of described lower clapboard is provided with apopore 15, this improvement makes the liquid water be separated automatically can discharge frequency converter through water hole and apopore, uses convenient.
What finally illustrate is, above embodiment is only in order to illustrate the technical solution of the utility model and unrestricted, although be described in detail the utility model with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify to the technical solution of the utility model or equivalent replacement, and not departing from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of right of the present utility model.
