Description
Technical field
The utility model relates to a kind of project organization that is applied in safe and reliable, easy for installation, the compact conformation in the photovoltaic DC-to-AC converter.
Background technology
Under the situation of photovoltaic industry develop rapidly, inverter apparatus uses more and more widely in our life, and power model is used by a large amount of, and wherein system's heating is also very serious, and the heat radiation of itself does not reach requirement.Be to connect between DC side positive pole, negative pole and the storage capacitor in the power control module with lead or busbar; Such connected mode is under the situation of switching; Because the influence of inductance can produce very high peak voltage between own and the connecting line, can influence the normal use of power model.And in traditional power device, control board, current sensor, extension set or the like great majority disperse, and this structure is being installed loaded down with trivial details and is being not easy to maintenance.
Summary of the invention
The purpose of the utility model provides a kind of simple installation, is convenient to keep in repair and dispel the heat good inverter apparatus.
In order to achieve the above object; The technical scheme of the utility model provides a kind of photovoltaic DC-to-AC converter IGBT radiator and direct current planar bus device; Comprise radiator, radiator connects radiator fan, and filtering capacitor is fixed on the filtering capacitor installing rack; It is characterized in that: IGBT and driver module are fixed on the radiator, are connected through planar bus between DC side positive pole in filtering capacitor and the power control module and the negative pole.
Preferably, on said filtering capacitor installing rack, lead to direct current planar bus negative pole and direct current planar bus positive pole.
Preferably, said planar bus comprises the red copper of two zinc-plated processing of process, separates said planar bus and the parallel connection of said filtering capacitor with insulating paper in the middle of two red coppers.
The utility model has the advantages that: 1, can finely must solve the whole temperature of power control unit, make system's operation more reliable and more stable; 2, satisfy electric creepage distance dielectric strength, reduce tens times than traditional connected mode inductance, can reduce power tube so greatly under the situation of cut-offfing, peak voltage reduces greatly, and power control module can operate as normal.
Description of drawings
A kind of photovoltaic DC-to-AC converter IGBT radiator and direct current planar bus device sketch map that Fig. 1 provides for the utility model;
A kind of photovoltaic DC-to-AC converter IGBT radiator and direct current planar bus device end view that Fig. 2 provides for the utility model.
Embodiment
For making the utility model more obviously understandable, now with a preferred embodiment, and conjunction with figs. elaborates as follows.
Like Fig. 1 and shown in Figure 2; A kind of photovoltaic DC-to-AC converter IGBT radiator and the direct current planar bus device that provide for the utility model; Comprise radiator 3; Radiator 3 connects radiator fan 1, and filtering capacitor 6 is fixed on the filtering capacitor installing rack 4, and IGBT2 and driver module are fixed on the radiator 3; It is anodal 7 on filtering capacitor installing rack 4, to lead to direct current planar bus negative pole 5 and direct current planar bus, passes through the parallel connection of planar bus between DC side positive pole in filtering capacitor 6 and the power control module and the negative pole.Planar bus comprises the red copper of two zinc-plated processing of process, separates with insulating paper in the middle of two red coppers, and said planar bus is connected with said filtering capacitor 6.
IGBT2 of the utility model and driver module are fixed on the radiator 3, and the radiator 3 following radiator fans 1 that connect can finely must solve the whole temperature of power control unit, make system's operation more reliable and more stable.Between DC side positive pole, negative pole and the filtering capacitor 6 in the power control module is to connect with planar bus, and this planar bus is that the centre separates with insulating paper with the zinc-plated processing of two red coppers processes; With 6 parallel connections of filtering capacitor; Satisfy electric creepage distance dielectric strength, reduce tens times, can reduce power tube so greatly under the situation of cut-offfing than traditional connected mode inductance; Peak voltage reduces greatly, and power control module can operate as normal.
