Description

A kind of inverter power module

Technical field

This utility model relates to the structural design of electric component, particularly relates to the structure to a kind of power model and improves.

Background technology

The defect of existing inverter power module essentially consists in:

1, power model the more commonly used at present is that electric capacity is just put, and general electric capacity is predominantly located in machine frame inside, causes the blocking of machine frame inside air channel or resistance to be greatly increased；

2, multiple electric capacity are usually before and after up and down and all align, and owing to ensure certain space between electric capacity, therefore the height of whole module is just relatively larger, thus cannot meet the occasion use that certain height requires；

3, the switching of capacitor bus-bar is generally positioned in bottom or rear portion, and the installation of such power model is safeguarded just very inconvenient.

Summary of the invention

Technical purpose of the present utility model is in that to solve the defect of above-mentioned prior art, it is provided that a kind of rationally distributed inverter power module, both ensure that electric capacity was firmly fixed and good conductive contact, and in turn ensure that the chamber, air channel that machine frame inside is good；Both ensure that certain space required between electric capacity, have compressed again the whole height of power model to greatest extent；And improve the convenience of power model installing/dismounting simultaneously.

Technical purpose of the present utility model realizes by the following technical solutions.

A kind of inverter power module that this utility model provides, including IGBT module, radiator, capacitance group, exchange output copper bar, insulated column, capacitor bus-bar, direct current input copper bar, circuit board, circuit board support, frame, panel, dust cover, especially also include capacitance bracket.Wherein: radiator, panel and dust cover are fixed in frame；IGBT module is fixing on a heat sink；In capacitance group, the bottom of each electric capacity is fixed on capacitance bracket, and the electrode of each electric capacity is connected with capacitor bus-bar；Capacitor bus-bar also has one end to be connected with direct current input copper bar, and one end again of capacitor bus-bar is connected with the both positive and negative polarity of IGBT module；The exchange pole of IGBT module is connected with exchanging output copper bar, and exchange output copper bar is fixed in frame.

In the technical solution of the utility model, it is fixed on capacitance bracket bottom each electric capacity in capacitance group, this back-off is fixed on the mode of Shelf External, both ensure that electric capacity was firmly fixed and good conductive contact, in turn ensure that the chamber, air channel that machine frame inside is good, it is to avoid because device stops the gas-flow resistance problems of too that air-flow causes.

In the technical solution of the utility model, the electric capacity in capacitance group can be divided into two groups, respectively upper row's capacitance group and lower row's capacitance group；Upper row's capacitance group and lower row's capacitance group in the vertical direction misplace half electric capacity width fixed installation.The mode of this staggered arrangement, between guarantee electric capacity under the premise of certain space, have compressed the whole height of inverter power module to greatest extent, thus being applicable to the occasion having certain height to require.

In the technical solution of the utility model, capacitor bus-bar directly inputs copper bar with direct current and is connected, direct current input copper bar can be transferred out by capacitor bus-bar, such direct current input copper bar is at the front portion of overall inverter power module, misplace in conjunction with half electric capacity width, just vacate certain altitude space, the screw hole at direct current input copper bar place just can be installed, so that just can assemble very easily and dismantle before power model.
