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 ventilation hole.
Frequency converter is generally mounted near the scene of motor simultaneously, and therefore in the course of the work, on-the-spot rainwater easily enters in frequency converter 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 rain-proof type frequency converter, to solve existing frequency converter easily by the problem of rain damage.
The utility model rain-proof type frequency converter, comprise housing, the bottom of described housing is provided with air inlet, the top of described housing has been arranged on air outlet, aerofoil fan is provided with in described air outlet, also comprise and be arranged on air inlet bottom and be provided with guide duct, in described guide duct, be provided with steam-water separator.
Further, the end of described air outlet is provided with right-angle elbow pipe.
Further, described steam-water separator comprises drier drawer and is contained in the desiccant particle in drier drawer, and the base plate of described drier drawer is provided with some air passing holes, and the diameter of described desiccant particle is 3 ~ 5mm; The sidewall of described guide duct is provided with the jack coordinated with drier drawer, described guide duct inwall is provided with the supporting bracket of carrying drier drawer.
The beneficial effects of the utility model:
The utility model rain-proof type frequency converter, it arranges steam-water separator by the air inlet bottom at frequency converter shell, by steam-water separator, drying is carried out to the cooling air entering frequency converter shell, thus make to avoid steam to electric elements damage in frequency converter, frequency converter failure rate can be reduced, extend frequency converter useful life.
Accompanying drawing explanation
Fig. 1 is the sectional structure schematic diagram of the utility model frequency converter.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further described.
As shown in the figure, the present embodiment rain-proof type frequency converter, comprise housing 1, the bottom of described housing is provided with air inlet 2, the top of described housing has been arranged on air outlet 3, be provided with aerofoil fan 4 in described air outlet, also comprise and be arranged on air inlet bottom and be provided with guide duct 5, in described guide duct, be provided with steam-water separator 6.
The present embodiment rain-proof type frequency converter, it arranges steam-water separator by the air inlet bottom at frequency converter shell, by steam-water separator, drying is carried out to the cooling air entering frequency converter shell, thus make to avoid steam to electric elements damage in frequency converter, frequency converter failure rate can be reduced, extend frequency converter useful life.
As the improvement to the present embodiment, the end of described air outlet is provided with right-angle elbow pipe 7, and this improvement can avoid rainwater to enter in frequency converter from blowing mouth, can further improve the water-resistant performance of frequency converter.
As the improvement to the present embodiment, the desiccant particle 62 that described steam-water separator 6 comprises drier drawer 61 and is contained in drier drawer, the base plate of described drier drawer is provided with some air passing holes, and the diameter of described desiccant particle is 3 ~ 5mm; The sidewall of described guide duct is provided with the jack coordinated with drier drawer, described guide duct inwall is provided with the supporting bracket 8 of carrying drier drawer; This improvement makes the easy accessibility of steam-water separator, is convenient to change and safeguard.
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.
