Abstract
The invention discloses a frequency converter shell. The frequency converter shell comprises a shell body, the shell is a rectangular cover with the bottom open, the side wall of the shell is provided with a plurality of heat dissipation holes, the top of the side wall is provided with dustproof cloth, the dustproof cloth is consistent with the side wall in size, and when a frequency converter does not work, the heat dissipation holes can be shielded, and dust can be prevented from entering the shell.
Description
Technical field
The present invention relates to the accessory of frequency converter, particularly a kind of shell 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 mainly made up of rectification (AC-DC), filtering, inversion (direct current becomes interchange), brake unit, driver element, detecting unit microprocessing unit etc.Voltage and the frequency of cut-offfing to adjust out-put supply of the inner IGBT of portion of frequency converter; provide its needed supply voltage according to the actual needs of motor, and then reach object energy-conservation, speed governing, in addition; frequency converter also has a lot of defencive functions, as overcurrent, overvoltage, overload protection etc.
Frequency converter can produce a large amount of heats in the process of work, if heat radiation not in time, will cause damage to the parts of frequency converter inside, in the useful life that shortens frequency converter, therefore, general shell of frequency converter is all provided with louvre, but dust can enter enclosure by louvre, to some precision parts of frequency converter, result in blockage, can shorten the useful life of frequency converter.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of dustproof shell of frequency converter, to solve the above-mentioned multinomial defect causing in prior art.
For achieving the above object, the invention provides following technical scheme: a kind of shell of frequency converter, comprise outer cover body, it is characterized in that: described shell is the uncovered rectangle cover in bottom, the sidewall of shell is provided with multiple louvres, the top of sidewall has been provided with dustcloth, and dustcloth size is consistent with sidewall.
Preferably, described cover top portion is provided with air inlet.
