Technical field
The utility model relates to a kind of pumped storage unit excitation system rectifier cabinet air channel that is applicable to, can provide a good heat dissipation environment for rectifying device in the rectifier cabinet, belongs to the structure-design technique field of electric cabinet.
Background technology
The pumped storage unit can be on the load peak as generator for electricity generation, also can be at load valley as the motor pumped storage, possess peak-clipping and valley-filling, frequency modulation phase modulation, emergency duty and flood storage and mend multiple uses such as withered, have start fast, be quick on the draw, Steam Generator in Load Follow characteristics rapidly.Compare with conventional power supply, hydroenergy storage station can adapt to the quick variation of load, played important function to improving power system safety and stability operation level, grid supply quality and reliability, simultaneously can also optimize power supply architecture, realize environmental protection, reach the overall energy-saving and cost-reducing of electric power system, improve overall economic benefits.In clean energy resource Large scale construction such as current nuclear power, wind-powered electricity generation and photovoltaic, must become the industry common recognition by a certain proportion of peaking power source of auxiliary construction, pumped-storage power generation is exactly one of optimal selection.
The pumped storage unit need dispose excitation system, by rectifying device three-phase alternating current is become direct current and provide exciting current for generator amature, form rotating magnetic field when rotor rotation, by the size of field regulator control exciting current, thereby the control generator is operated in different states.Rectifying device generally partly is made up of thyristor device, fin and capacitance-resistance absorption etc., and adopting the forced air cooling mode usually is the rectifying device heat radiation.Generally rectifying device is installed in the airtight air channel in the rectifier cabinet, in the air channel, forms high velocity air, with fin and absorb the power station and the capacitive surface heat is discharged, in order to avoid rectifying device is crossed cause thermal damage with the mode of cooling blower by blowing or exhausting.
Switch between the operating modes such as the pumped storage unit will generate electricity and draw water through being everlasting, start and stop are frequent, its excitation system rectifier cabinet is also wanted frequent switching conversion, the operation of cooling blower and stall conversion are much more frequent than the conventional hydropower unit, the air channel internal pressure that the air channel can cause along with the start and stop of cooling blower changes and deformation frequently takes place, and therefore just the design in air channel is had higher requirement.
Summary of the invention
The purpose of this utility model is to propose a kind of a kind of novel rectifying cabinet air channel that can satisfy the requirement of pumped storage unit excitation system rectifier cabinet frequent start-stop.
In order to realize the foregoing invention purpose, the utility model adopts following technical scheme:
Pumped storage unit excitation system rectifier cabinet air channel, comprise the shutter air inlet that is positioned at front and back, cupboard bottom door, the air outlet that converges bellows, front panel, rear board, rectifier cabinet left and right side cabinet and cupboard top, whole vertically state, the fin that also comprises vertical installation, cold air is dried to the air channel along the remittance bellows by air inlet, form air-flow in the air channel, the spreader surface heat is taken away, hot blast is discharged from air outlet.
The beneficial effects of the utility model are, with inner rectification circuit insulation, transparent weather-proof, install firm, elegant in appearance, be convenient to observe and safeguard, in addition for preventing that panel from damaging because of frequent deformation, adds square iron framework and fixed on panel.Rear board adopts epoxy plate to make, and epoxy plate stable insulation, mechanical strength height, good processability, convenient fluting are installed copper bar.Whole air channel design flow is smooth, convenient for installation and maintenance, and cooling effect is good, satisfies on-the-spot service requirement.
Description of drawings
Fig. 1 is pumped storage unit excitation system rectifier cabinet air channel structure figure.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described.
Structure chart of the present utility model as shown in Figure 1, cupboard is a pumped storage unit excitation system rectifier cabinet among the figure, among turbine type cooling blower M1 and the M2(figure 6) be positioned at the cupboard bottom, among the thyristor assembly SCR1-SCR6(figure that thyristor device and fin are formed 4) and the capacitance-resistance absorption plant that constitutes of resistance (R1-R12 among the figure) and electric capacity (C1-C6 among the figure) (among the figure 1) be fixed on inside, air channel in the middle part of the cupboard.The air channel by shutter air inlet (among the figure 7), converge bellows (among the figure 5), front panel (installation region is shown among the figure 3), rear board (3 opposite among the figure), rectifier cabinet left and right side cabinet and air outlet (among the figure 0) and form, become vertical state, therefore fin is also vertically installed, the capacitance-resistance absorption plant is positioned at thyristor assembly top, fin and capacitance-resistance absorption plant support by rear board, and three-phase alternating current input and direct current output are passed the air channel rear board by copper bar and drawn.Door leaves the shutter air inlet before and after the cupboard bottom, and air outlet is arranged at the top, and cold air was dried to the air channel along the remittance bellows by air inlet when blower fan rotated, and forms air-flow in the air channel, and the spreader surface heat is taken away, and hot blast is discharged from air outlet.For preventing that dust or foreign material from entering the air channel, reverse deep bead is installed in the shutter liner screen pack, air outlet, deep bead is closed air outlet when blowing-out.
Rectifier cabinet adopts steel bar framework, and each is sealed the left and right side by three iron plates of upper, middle and lower, at thyristor area side panel plastic lining thin plate, in case iron plate and the short circuit of thyristor assembly.The bellows that converge are to be made of front and back iron plate and rectifier cabinet left and right side, the wind of two blower fans is pooled together, increased the insulation distance between blower fan and the thyristor assembly simultaneously, if having only a blower fan job, the bellows that converge can make the inner each point wind speed in air channel more even.Air channel front panel material is selected acrylic board, it has that high light transmittance, good machining property, good weatherability, excellent electric insulating, anti-impact force are strong, resistance to chemical attack, hardness height, in light weight, the life-span is long, cost is low, can see through panel and see the air channel inner case, use screw to fix (among the figure 2), be easy to dismounting, make things convenient for the user to observe and safeguard the rectifying device of inside, air channel.Because the start and stop of pumped storage unit excitation system rectifier cabinet are frequent, deformation can frequently take place because the air channel pressure inside changes in panel, breaks because of frequent movement for preventing fixing point, a square iron plate framework is installed on the panel fixing point is fixed.The air channel rear board adopts epoxy plate to make, and epoxy plate stable insulation, mechanical strength height, good processability, convenient fluting are installed copper bar.Distance between front and back panel and left and right sides iron plate and the thyristor assembly should be as far as possible little, to improve result of ventilating heat dissipation, will prevent short circuit by the plastic lining thin plate between left and right sides iron plate and thyristor assembly for this reason.
