Description
Technical field
The utility model belongs to electrical equipment, is specifically related to a kind of frequency converter, the extraordinary frequency converter of especially a kind of high-protection level.
Background technology
Along with the development of power electronic technology, the application of frequency converter in the numerous areas such as power electronic system, industry is increasingly extensive, general common frequency converter sealing is more weak, and degree of protection is lower, if in the poor occasion of environment (as dye-works, Electroplate Factory, chemical plant) under application, because these enterprise's dust in air are many, steam is many, also be flooded with corrosive gas in some chemical enterprise, such operational environment can affect the useful life of frequency converter to a great extent.Also a lot of enterprise is had to develop waterproof and dampproof extraordinary frequency converter at present, the technical scheme of general employing is that host shell is carried out Seal Design, host shell bottom arranges heat dissipation channel, but because the accessibility of gas is strong, and host shell also will do maintainability dismounting once in a while, pernicious gas in adverse circumstances still can invade in host shell and cause damage to frequency converter, secondly radiating effect can be reduced after host shell has carried out Seal Design, and the input-output line of radiator fan and frequency converter and control line wiring junction also can make moist and corroded, affect useful life,
Summary of the invention
The purpose of this utility model is: release that a kind of sealing is strong, degree of protection is high, good heat dissipation effect, be suitable for use in the extraordinary frequency converter of high-protection level of the poor occasion of environment.
The purpose of this utility model is achieved in that it comprises the main case that adopts hermetically sealed design, main case encloses a main frame cavity, main frame cavity is built-in with the main frame core of CPU, drive plate, control board, inversion module composition, it is characterized in that: outside described main case, be arranged with heat-dissipating cavity, main frame cavity and heat-dissipating cavity isolation and separate, heat-dissipating cavity air inlet is below main frame cavity, be provided with drip-proof fan in heat-dissipating cavity air inlet, heat-dissipating cavity air outlet is arranged on above main frame cavity.
All circuit board elements of described main frame core all carry out three anti-process.
Described main case free section adopts water proof rubber sealing strip to seal.
Input-output line and the control line of frequency converter all adopt water joint to be connected.
Like this, when frequency converter is in harsh environments, dust in environment, steam and corrosive gas can not invade in main frame cavity substantially, even if there is a small amount of pernicious gas to invade, because the circuit board element of main frame core had carried out three anti-process, also the damage to main frame core can not be caused, although the heat-dissipating cavity being located at main frame cavity periphery is not hermetically sealed, but due to main frame cavity and heat-dissipating cavity isolation and separate, therefore can not pernicious gas be brought in main frame cavity, and main case free section also adopts water proof rubber sealing strip to seal, achieve the strong sealing of main frame, radiator fan adopts drip-proof fan, and input-output line and the control line of frequency converter all adopt water joint to be connected, and are conducive to the raising of frequency converter integral protection grade.The heat accumulation distributed due to frequency converter is above main case and side, therefore heat-dissipating cavity air inlet is arranged on below main frame cavity, and heat-dissipating cavity air outlet is arranged on above main frame cavity, carries out air blast cooling by drip-proof fan, cold wind is discharged from bottom to top along heat-dissipating cavity, and radiating effect is better.
