Fig. 4: the schematic perspective view of casing among the utility model embodiment.
As Fig. 1, shown in 2, the utility model " AC power supply " embodiment, mainly be to utilize the many groups capacitance group 20 in the power supply unit casing 10 to connect array power modules 30, and on the power modules 30 and be provided with shock absorption circuit plate 40, power modules 30 is subjected to the driving of a drive circuit board 50, and drive circuit board 50 is the driver circuit of an insulation lock bipolar transistor (worker GBT), and drive circuit board 50 is connected to master control borad 60, when the input power supply, main power source enters in the capacitance group 20 via a rectification module 70, the control power supply is then supplied master control borad 60 and drive circuit board 50 simultaneously, at this moment, voltage by the 30 output settings of control panel 80 operation master control borads 60 control Driver Circuit plates 50 driving power modules, as Fig. 2, shown in 3, in the casing 10 of power supply unit, be provided with a machine plate 11, offer several capacitance group storage tanks 111 on the machine plate 11, be installed with an air gathering plate 12 at capacitance group storage tank 111 sides, capacitance group 20 can be expanded into 2 according to power output, 3,5 ... plurality of specifications such as 15KV, to be applicable to different type of machines, present embodiment is for adopting 7.5KV, capacitance group 20 devices are in capacitance group storage tank 111, borrow the copper bus 21 of lath-shaped to be connected to power modules 30, and power modules 30 is fixed on the upside of air gathering plate 12, and 30 of shock absorption circuit plate 40 and power modules combine with copper post 31, next-door neighbour's power modules 30 sets firmly drive circuit board 50 on air gathering plate 12, shorten with the wiring 51 of drive circuit board 50 so that connect power modules 30, and wiring 51 and utilize quick detach terminal 52 to connect, on machine plate 11, one side next-door neighbour's power modules 30 of air gathering plate 12 is installed with a division board 13 made from magnetic conductive metal, 60 lateral surfaces that are fixed on division board 13 of master control borad, again, one end of air gathering plate 12 is provided with a radiator fan 14, so that forced heat radiation to be provided, in addition, as shown in Figure 4, the bottom of power supply unit casing 10 is provided with array pulley 15, casing 10 fronts are provided with mains switch 16,17, mains switch 16,17 adopt the indent setting, the back side of casing 10 is provided with output, input terminal 18,19, output, input terminal 18,19 adopt built-in configuration.
Operating position of the present utility model and the obtainable effect of institute are as follows:
30 of capacitance group 20 and power modules are connected with the copper bus; adopt shortest path; make the obstruction of capacitance group output reduce to minimum; and shock absorption circuit plate 40 combines with the copper post 31 of power modules 30 with tubbiness; make on-state rate therebetween preferable; equiva lent impedance reduces; can eliminate bus and switch the noise that surging produces; with protection power modules 30; 30 configurations of drive circuit board 50 next-door neighbour's power modules; wiring 51 is therebetween shortened; quick detach terminal 52 fixed-site of wiring 51; can not damage power modules 30 because of mistake misplugs; simultaneously in assembling; also very convenient in the maintenance; and wiring 51 is shorter; its impedance phase is to less; the pressure drop of passing through is also less; so during drive circuit board 50 driving power modules 30; do not have power loss; again; on machine plate 11; one side next-door neighbour's power modules 30 of air gathering plate 12 is installed with a division board 13 made from magnetic conductive metal; 60 lateral surfaces that are fixed on division board 13 of master control borad; because of next-door neighbours such as master control borad 60 and power modules 30 by putting, the assembly space is dwindled, also shorter at the winding displacement of 60 of drive circuit board 50 and master control borads; can reduce noise; division board 13 then can prevent master control borad 60 and the mutual interference mutually of other interelement, and in addition, power modules 30 elements such as grade are to be installed in jointly on the air gathering plate 12; do by the radiator fan 14 of air gathering plate 12 1 sides and to force heat radiation, can effectively prevent over-heat inside and damage electronic component.
What deserves to be mentioned is that the capacitance group 20 in the utility model can suitably be expanded into 2,3,5,7.5 ... all sizes such as 15KV are so can be applicable to the type of different size, demand.
In addition, the bottom of casing 10 of the present utility model is provided with pulley 15, it can be moved arbitrarily, more increase its mobility, and adopt the indent formula, can prevent false touch at the mains switch 16,17 of casing 10, influence the carrying out of test job, and this output, input terminal 18,19 are built-in, then can avoid personnel's false touch, and the danger of getting an electric shock takes place.
Because each element next-door neighbour configuration, distribution is shorter, and its on-state rate is preferable, and equiva lent impedance is little, improves usefulness; Assemble easy to maintenancely, can prevent mistake, and can reduce noise and disturb, and can be applicable to different types of machines.
