Abstract
The utility model discloses an arranging structure of inverter power tubes of a digital generator, which comprises a shell body and four power tubes which are positioned in the shell body, wherein the four power tubes are connected with an inversion main circuit through wires and form a full-bridge inversion circuit, two to four dispersed concaves are arranged on the shell body, the four power tubes are separately arranged in the concaves, and the wires are arranged in a groove, and the concaves and the groove are covered by an electromagnetic screening plate. The structure is characterized by separately arranging two to four concaves and enables the heat which is generated by the power tubes to be homogeneously distributed on the whole shell body, which is beneficial to the heat dissipation. After the power tubes and the wires are covered by the screen plate, the electromagnetic screening is realized.
Description
Technical field
The utility model relates to a kind of digital generator inverter, relates to the new arrangement of a kind of digital generator inverter power tube particularly.
Background technology
Inverter is the core component of digital electricity generating, and its reliability has determined that contravariant internal combustion engine generator unit is the performance of digital electricity generating.Inverter is a direct current with the three-phase alternating current elder generation rectification that magnetic generator sends, and another mistake becomes stable 50Hz of voltage or 60Hz sinusoidal ac.The rectification of inverter, inversion all can have power loss, and this electric energy loss meeting is converted into heat energy.Inverter power is big more, and the heat that sends is also many more, and this heat can cause that then the inverter temperature raises if can not well distribute, and the inverter temperature is elevated to a threshold value, then can't continue normal output.
The heat that inverter work is sent is mainly produced by power tube.Power tube in the inverter mainly uses IGBT (Isolated Gate Bipolar Transistor insulation gate pole bipolar transistor), and 4 IGBT single tubes constitute full bridge inverter.At present, common arrangement is that 4 IGBT are placed in the pit in the inverter case side by side jointly.Such arrangement is for installing easily, and can solve electromagnetic interference problem preferably, heat radiation is disadvantageous but this arrangement is to inverter, 4 IGBT generate heat simultaneously and will distribute in a common confined space, this is obviously unfavorable in heat radiation, particularly be used in as more than the 3KW than the high power contravariant device time, can make inverter because of the temperature rise of IGBT position is too high can't operate as normal.
The utility model content
At the prior art above shortcomings, the purpose of this utility model provides the new arrangement of a kind of digital generator inverter power tube, and this arrangement can solve the heat dissipation problem of inverter well.
The technical solution of the utility model is achieved in that digital generator inverter power tube arrangement, comprise housing and four power tubes that are positioned at housing, four power tubes connect and compose full bridge inverter by lead and inverter main circuit, on housing, be provided with the pit of two to four dispersions, four power tubes disperse to be located in the pit, lead is located in the groove, and pit and groove are hidden by electromagnetic shielding plate.
Described pit is four, and each pit is provided with a power tube; Pit also can be two, and each pit is provided with two power tubes.
The utility model disperses to be provided with two to four pits, and four power tubes disperse to be located in the pit, and the heat that power tube is sent is uniformly distributed on the whole housing, is beneficial to integral heat sink.After by barricade power tube and lead being hidden, realize electromagnetic shielding.
Description of drawings
Fig. 1-the utility model structural representation.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
Referring to Fig. 1, from the figure as can be seen, digital generator inverter power tube arrangement of the present utility model, 2, four power tubes 2 of four power tubes that comprise housing 1 and be positioned at housing connect and compose full bridge inverter by lead 3 and inverter main circuit.Disperse to be located in the pit 4 at 4, four power tubes of the pit that is provided with two to four dispersions on the housing 12.The dispersion here is for four power tubes concentrate on a pit setting, and promptly each pit all is provided with power tube, and the power tube quantity in the pit can be identical, also can be different.Fig. 1 is a specific embodiment, and 4, four power tubes 2 of pit that are provided with four dispersions in four corners of housing 1 are located at respectively in four pits 4.
Pit also can be two, and each pit is provided with two power tubes.Can certainly place a power tube by a pit, another pit is placed three power tubes.Equally, pit also can be three, and one of them pit is placed two power tubes, and two pits are respectively placed a power tube in addition.The dispersed placement power tube can make full use of whole housing heat radiation, and the radiating effect of four pits is best.Pit can be located at the housing corner, also can not be located at the housing corner, is provided with as long as disperse.
Fluted 5 between the pit of settling power tube and converter main circuit, lead 3 just is placed among the groove 5.After installing power tube, putting lead well, pit, groove hide with aluminium sheet, and are screwed, and realize electromagnetic shielding.
