Abstract
The utility model discloses an aggregate shunt capacitor, including a core body, a shell, a fuel tank, an outlet casing tube and cooling components, wherein, the core body is arranged in the case, the core body is composed of a plurality of entirely sealing small unit of capacitors in parallel-series connection, all the components of small unit of capacitors are in parallel connection; the shell is filled with insulated cooling oil; the upper end-face of the shell is provided with the fuel tank and the outlet casing tube, the fore-and-aft flanks of the shell are provided with cooling components. The aggregate shunt capacitor can compensate reactive power of the traction net, reduce the backward sequence component, improve the voltage quality, reduce current and voltage harmonic component; and has simple structure, reliable operation and easy maintenance.
Description
Technical field
The utility model relates to a kind of power capacitor, more precisely relates to a kind of assembling shunt capacitor.
Background technology
At present, China railways realizes electrified substantially, electric railway speed is fast, transport capacity is strong, power supply distance is long, hauling ability is good, owing to the speed-raising of present stage China Railway train, the increase of vehicle density and loading capacity constantly increases traction load, the voltage fluctuation of traction net is excessive, reactive power compensation measure imperfection, the harmonic pollution of traction net is because the load unbalanced negative sequence component that causes increases; The load of electric railway is special, and the harmonic wave that is produced, negative phase-sequence not only have influence on the power supply reliability of traction station of electrical railroad, and the safe and reliable operation of local electrical network has also been produced very adverse influence.The electric power system of existing electric railway has been difficult to satisfy the demand of high speed development.
The utility model content
In order to address the above problem, the utility model provides a kind of assembling shunt capacitor, and this shunt capacitor can not only compensate the reactive power of traction net, can reduce negative sequence component simultaneously, improves quality of voltage, reduces the harmonic component of electric current and voltage.
The purpose of this utility model realizes by following scheme: a kind of assembling shunt capacitor, comprise fuse main body, shell, fuel tank, outlet sleeve pipe and radiating subassembly, described fuse main body is arranged in the described shell, described fuse main body is formed by a plurality of hermetically sealed junior unit capacitors and string, and the element of described junior unit capacitor is all in parallel; The described envelope filled cold oil that completely insulate, described fuse main body immerses in the described insulation cold oil; The upper surface of described shell is provided with described fuel tank and three described outlet sleeve pipes, and the front and back sides of described shell is provided with described radiating subassembly.
Adopt this kind assembling shunt capacitor to have following beneficial effect:
1. can compensate the reactive power of traction net, reduce negative sequence component, improve quality of voltage, reduce the harmonic component of electric current and voltage.
2. assembling shunt capacitor is not only simple in structure, and floor space is little, and blast protection, and is anti-on fire, reliable, easy to maintenance.
Description of drawings
Accompanying drawing is the structural representation of the utility model assembling shunt capacitor.
Among the figure: 1. fuse main body, 2. shell, 3. outlet sleeve pipe, 4. fuel tank, 5. radiating subassembly, 6. junior unit capacitor, 7. insulation cold oil, 8. loam cake, 9. binding post, 10. lead.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model assembling shunt capacitor is further described:
Among the figure, by a plurality of junior unit capacitors 6 strings and connect to form fuse main body 1, fuse main body 1 is provided with binding post 9, fuse main body 1 places in the shell 2, insulation cold oil 7 is filled with in sealing around the shell 2 in the shell 2, fuse main body 1 is dipped in the insulation cold oil 7 fully.The top of shell 2 is provided with loam cake 8, be fixed with outlet sleeve pipe 3 and fuel tank 4 above the loam cake 8, lead 10 1 ends connect binding post 9, the other end is drawn from outlet sleeve pipe 3, outlet sleeve pipe 3 is arranged on the front of fuel tank 4, fuel tank 4 communicates with shell 2, and the two sides, front and back of shell 2 are separately installed with radiating subassembly 5, and radiating subassembly 5 inside have oil duct to communicate with the inner chamber of shell 2.
During use, fuse main body 1 is put into shell 2, cover loam cake 8 and sealing, to fuel tank 4 in, inject the cold oil 7 and filling with of insulating.The heat that fuse main body 1 is produced when work takes in the radiating subassembly 5 by insulation cold oil 7, and heat is distributed.
The utility model assembling shunt capacitor is attempted by it on traction side high voltage bus when mounted, is connected into group by several capacitor series and parallel, is in series with reactor again.Because capacitor has overvoltage, current capacity is relatively poor, after the outage residual voltage is arranged, close a floodgate and send electricity can produce overvoltage and characteristic such as shove, be equiped with lightning arrester, fuse, discharge coil and reactor etc. and protected.The electric charge that discharge coil stores in order to releasing capacitor, reduction residual voltage, inrush phenomenon that produces when preventing to send electricity once more and overvoltage; Inrush phenomenon when series reactor is used for the restraining device input, the high order harmonic component that absorbs the traction load generation also prevents the capacitor group and system's generation high order harmonic component parallel resonance.
The utility model assembling shunt capacitor mainly is the reactive power that is used for compensating the traction net, can be installed in electric substation and the online any point of traction, equally also can be installed in and make local compensation on the locomotive.This shunt capacitor divides variable capacity and two kinds of forms of non-adjustable capacity, is used to reduce negative sequence component in compensating reactive power consumption again, improves quality of voltage, reduces the harmonic component of electric current and voltage.
