Description
Technical field
This utility model is that a kind of shore electric power based on converter realizes equipment, belongs to shipyard electromechanical equipment field.
Background technology
In prior art, the major function of shipyard is exactly assembled by each parts of boats and ships, then by the parts of assembling by welding or being attached by bolt, finally carry out equipment debugging, and then make boats and ships be free to navigate by water in inland river or ocean, and the words carrying out navigating by water in ocean will run into wind and waves, and then the structure of hull is caused certain damage, and it is accomplished by firmly weld in this course when building hull, so being accomplished by careful being operated of staff in the process of welding, and ensure internal unit reliably working.Additionally original implementation device dispersion, integrated level is too low, single-machine capacity is limited, maximum can only accomplishing 1000KVA, needed for shipyard, power supply is all several thousand more than KVA, and unit cannot meet use, and reliability is low, inconvenient operation, user will be caused certain puzzlement by this, so needing a kind of shore electric power equipment based on converter to realize the problems referred to above.
Utility model content
For the deficiency that prior art exists, this utility model purpose is to provide a kind of shore electric power based on converter and realizes equipment, by adding the problem that power transformer, three-phase reactor and isolating transformer solve to propose in above-mentioned background technology, this utility model is easy to use, it is easy to operation, good stability, reliability is high.
To achieve these goals, this utility model is to realize by the following technical solutions: a kind of shore electric power based on converter realizes equipment, including power transformer, converter, three-phase reactor, filter capacitor and isolating transformer, described power transformer is connected with converter, described converter is connected with three-phase reactor, described three-phase reactor is connected with filter capacitor, and described filter capacitor is connected with isolating transformer.
Further, described filter capacitor is mounted in a kind of filtering device of three-phase reactor rear end.
Further, described filter capacitor is provided with three electric capacity.
The beneficial effects of the utility model: a kind of shore electric power based on converter of the present utility model realizes equipment, the process of low-voltage is realized being converted into voltage from high voltage by adding power transformer, this design is easy to voltage is realized controlled adjustment, and converter exports after carrying out rectification inversion again, radio-frequency component is filtered by the wave filter through being made up of three-phase reactor and filter capacitor, formation standard first-harmonic sinusoidal voltage, isolate then through output isolation transformer, boosting, voltage needed for becoming equipment is carried outward, meet load to use, this design effectively raises single-machine capacity of the present utility model, and then improve the convenience of boats and ships debugging to a certain extent.This utility model is easy to use, it is simple to operation, good stability, and reliability is high.
Accompanying drawing explanation
By reading detailed description non-limiting example made with reference to the following drawings, other features, objects and advantages of the present utility model will become more apparent upon:
Fig. 1 is the structural representation that a kind of shore electric power based on converter of this utility model realizes equipment；
In figure: 1-power transformer, 2-converter, 3-three-phase reactor, 4-filter circuit, 5-isolate circuit.
Detailed description of the invention
For the technological means making this utility model realize, creation characteristic, reach purpose and effect and be easy to understand, below in conjunction with detailed description of the invention, this utility model is expanded on further.
nullRefer to Fig. 1，This utility model provides a kind of technical scheme: a kind of shore electric power based on converter realizes equipment，Including power transformer 1、Converter 2、Three-phase reactor 3、Filter capacitor 4 and isolating transformer 5，Power transformer 1 is connected with converter 2，Realize being converted into voltage from high voltage the process of low-voltage by adding power transformer 1，This design is easy to voltage is realized controlled adjustment，Converter 2 is connected with three-phase reactor 3，Three-phase reactor 3 is connected with filter capacitor 4，Filter capacitor 4 is connected with isolating transformer 5，Converter 2 exports after carrying out rectification inversion again，Radio-frequency component is filtered by the wave filter through being made up of three-phase reactor 3 and filter capacitor 4，Formation standard first-harmonic sinusoidal voltage，Isolate then through output isolation transformer 5、Boosting，Voltage needed for becoming equipment is carried outward，Meet load to use.
Filter capacitor 4 is mounted in a kind of filtering device of three-phase reactor 3 rear end, is provided with three electric capacity in filter capacitor 4.
nullDetailed description of the invention: when using，First this utility model is checked by staff，Check for defect，If existing defects just cannot be carried out employing，Notice maintainer is now needed to keep in repair，Inspection again is carried out after maintainer has keeped in repair，If there is no the words of problem can be carried out employing，During use，First it is connected in circuit by power transformer 1，Then power supply is started，Now electric current is transferred in power transformer 1，Then under the effect of power transformer 1, high voltage is converted into the voltage that converter 2 adapts to，Then pass through three-phase reactor 3 to be filtered out by radio-frequency component with filter capacitor 4，It is subsequently formed standard first-harmonic sinusoidal voltage，Isolate then through input isolating transformer 5，Then low-voltage is boosted，And then meet the voltage requirements needed for equipment，Last voltage flows to the equipment needed for the external world，Hull interior equipment can be debugged by final shipyard，Thus ensureing the safe and reliable work of equipment.
Of the present utility model ultimate principle and principal character and of the present utility model advantage have more than been shown and described, to those skilled in the art, obvious this utility model is not limited to the details of above-mentioned one exemplary embodiment, and when without departing substantially from spirit of the present utility model or basic feature, it is possible to realize this utility model in other specific forms.Therefore, no matter from which point, embodiment all should be regarded as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims rather than described above, it is intended that all changes in the implication of the equivalency dropping on claim and scope included in this utility model.Any accompanying drawing labelling in claim should be considered as the claim that restriction is involved.
In addition, it is to be understood that, although this specification is been described by according to embodiment, but not each embodiment only comprises an independent technical scheme, this narrating mode of description is only for clarity sake, description should be made as a whole by those skilled in the art, and the technical scheme in each embodiment through appropriately combined, can also form other embodiments that it will be appreciated by those skilled in the art that.
