Description
Technical field
The utility model relates to frequency converter, particularly a kind of frequency converter of high-power compactization.
Background technology
At present the 15KW frequency converter causes the assembling complexity because the restriction of substrate through-current capability mostly adopts the mode of the lead or the bronze medal that confluxes to connect input and output terminal and electronic components such as major loop capacitor and IGBT, cost height, shortcoming such as volume is big.The major loop electrochemical capacitor is because 85 ℃/105 ℃ 5000 hours electric capacity products are mostly adopted in the temperature rise and the restriction in life-span, and cost is higher.
The utility model content
At the above-mentioned defective of existing frequency converter, the utility model provides a kind of assembling complexity that reduces, and life-saving is saved man-hour, the high-power compact frequency converter that reduces cost.
The technical solution of the utility model is as follows:
A kind of high-power compact frequency converter, comprise a casing that is used to install each device, it is upright upright with the dividing plate groups of fins that the bottom of described casing is arranged side by side with capacitance group, the upright outside of capacitance group is stopped that by the lower side panel that is installed on the casing side it is upright that the upright outside of dividing plate groups of fins is equipped with the fan group; The upright upright upper surface of capacitance group that is installed in of terminal board group, the upright upright upper surface of dividing plate groups of fins that is installed in of power supply board IGBT group; The control basal plate group is upright be installed in the upright and terminal board group of power supply board IGBT group upright on, the upright outside of described power supply board IGBT group is stopped by the epipleural that is installed on the casing side, on the described epipleural resistance is installed; Described casing is equipped with cover topmost.
Its further technical scheme is: the upright upright air inlet position of dividing plate groups of fins that is installed in of described capacitance group.The volume of described casing is W200 * H320 * D200.It is upright and fix with screw that described power supply board IGBT group vertical cutting is gone into the terminal board group.The upright substrate of described capacitance group adopts the PCB of 2 layers of 4OZ.
Useful technique effect of the present utility model is:
The utility model frequency converter machine adopts the PCB of 4OZ to increase the through-current capability of substrate, and adopted substrate has directly been designed with the mode that screw and terminal board link, save space and built-up time greatly, also saved a lot of connecting lines and bronze medal, thereby reduced cost.The installation site of major loop electrochemical capacitor is placed on the air inlet of radiator, this position is the minimum position of whole frequency converter temperature, because temperature is to influence most important factor of electrochemical capacitor life-span (reducing by 1 times of 10 ℃ of life-spans increase), design can improve the designed life of frequency converter significantly like this.Should 85 ℃ of electric capacity products of 2000 hours can be selected for use by this electrolytic capacitor, thereby cost can be saved.
