Technical field
The utility model belongs to converter technology field, and in particular to a kind of hermetically sealed shell structure of frequency converter.
Background technique
Frequency converter is to be handed over using converter technique and microelectric technique by changing motor frequency mode of working power supply to control
The electric control appliance of galvanic electricity motivation.
Frequency converter is mainly by rectifying（AC to DC）, filtering, inversion（Direct current becomes exchange）, brake unit, driving unit,
The composition such as detection unit microprocessing unit.IGBT cut-offs to adjust the voltage of out-put supply and frequency, root frequency converter close to the inner portion
Supply voltage required for it is provided according to the actual needs of motor, and then achievees the purpose that energy conservation, speed regulation, in addition, frequency converter
There are also many defencive functions, such as overcurrent, over-voltage, overload protection.With the continuous improvement of industrial automatization, frequency conversion
Device also has been widely used.
Common most of shell of frequency converter body on the market, can only carry out simple mechanical protection, poor sealing effect.
Utility model content
In view of the above-mentioned problems, the utility model provides a kind of hermetically sealed shell of frequency converter, can by frequency converter with
External world's isolation, sealing effect are good.
Its technical solution is such：A kind of hermetically sealed shell structure of frequency converter, including main casing and lid are mounted in described
