Abstract
The utility model relates to a realize inverter unit of insulating installation of IGBT, including bottom plate, radiator mounting box, diode radiator, IGBT module radiator, the radiator mounting box is fixed on the bottom plate, and diode radiator and IGBT module radiator are installed in the radiator mounting box, and the diode is fixed on diode radiator, and the IGBT module is fixed on IGBT module radiator, and the radiator mounting box adopts the SMC forming, the IGBT module utilizes female the arranging of stromatolite to be connected with the diode. Compared with the prior art, the utility model discloses utilize the interval of SMC forming itself to realize the electric isolation between each radiator to avoid the module to damage because of bearing the high voltage, both solved the withstand voltage not enough problem of IGBT, still improved the installation effectiveness, the copper bar adopts the female row of compound stromatolite, can effectively reduce circuit distributed inductance, has dwindled the unit volume simultaneously, has also had the large increase on the installation effectiveness.
Description
Technical field
The present invention relates to a kind of medium voltage frequency converter inversion unit, be a kind of inversion unit being capable of IGBT insulating mounting in particular.
Background technology
If converter wants to realize pressure output in 2300V, then inversion module needs with pressure 3300V, but this grade Module Price costliness and delivery cycle are long.Way both economical at present is to use multiple 1700V62mm to encapsulate IGBT module series connection, and this technique is primarily present problems with: (1) IGBT module is pressure not.Needing to increase high pressure resistant insulation cloth during use between module and radiator, this assembling is complicated and electrical isolation is unreliable, affects radiating effect.(2) busbar needs to carry out insulation processing, and machine volume is big.(3) three-phase inversion part is in one plane, and installation difficulty is relatively big, and man-hour is longer, and cannot parallel work-flow in installation process.
Summary of the invention
It is an object of the invention to the deficiency for existing existence, it is provided that a kind of inversion unit realizing IGBT insulating mounting.
It is an object of the invention to be realized by techniques below means:
Including base plate, radiator mounting box, diode radiating device, IGBT module radiator, radiator mounting box is fixed on base plate, diode radiating device and IGBT module radiator are arranged in radiator mounting box, diode is fixed on diode radiating device, IGBT module is fixed on IGBT module radiator, and radiator mounting box adopts SMC molding；IGBT module utilizes stack bus bar to be connected with diode.
Compared with prior art the present invention has following clear advantage: utilize the interval of SMC molding itself to realize the electrical isolation between each radiator, thus avoiding module to damage because bearing high voltage, both solve the pressure inadequate problem of IGBT, also improve installation effectiveness；Copper bar adopts composite laminate busbar, it is possible to effectively reduces circuit distributed inductance, reduces unit volume simultaneously, there has also been large increase on installation effectiveness.
