Abstract
The utility model relates to a constant frequency electric supply device of a main engine AC (alternating current) shaft generator with an electric power converter, which comprises a driving connection device and the generator, and is characterized in that the inner part of the generator at least adopts three groups of mutually-isolated stator windings, wherein three ways of output of the generator are connected with three groups of single phase inverters, and the single phase inverters are connected with an electrical device through an output switch. By directly adopting the thinking that the inner part of the generator is isolated, external isolation transformers can be omitted, so the cost and the mounting space of the device are greatly saved and the efficiency of the whole system can be improved.
Description
Technical field
The utility model relates to a kind of rotor machine, specifically is a kind of main frame shaft alternator constant frequency electric supply installation with power converter.
Background technology
The shaft generator device of well-known charged force transformation can provide the constant AC power of voltage and frequency under the situation of engine speed change, the alternating current of the output of generator need be handled through the inversion and the transformation of inverter and isolating transformer in actual applications, therefore the volume of whole generator is relatively large, and cost and maintenance cost are also higher.
Summary of the invention
The purpose of this utility model is to provide a kind of main frame shaft alternator constant frequency electric supply installation with power converter, generator adopts three groups of stator winding of isolating mutually at least, convert one group of original three-phase output to direct three groups of three-phases output, adopt the thinking of direct-power generator internal insulation, can save external isolating transformer, save the cost and the installing space of this device greatly, and can promote overall system efficiency.
For achieving the above object by the following technical solutions:
A kind of main frame shaft alternator constant frequency electric supply installation with power converter, comprise and drive coupling arrangement and generator, it is characterized in that: described generator inside is adopted three groups of stator winding of isolating mutually at least, wherein three tunnel outputs of generator are connected with three groups of single-phase inverters, and single-phase inverter is connected with power device by the output switch.
Adopt four groups of stator winding of isolating mutually in that described generator is inner, wherein three the tunnel are connected with single-phase inversion, and another road is connected with controllable rectifying device, and controllable rectifying device links to each other with the storage battery of outside.
Generator of the present utility model has three groups or the three isolation generating outputs of forming, wherein three groups be used for by three road single-phase inverters respectively inversion be combined into three-phase alternating current output, generating by generator inside is isolated, can omit the necessary isolating transformer that inputs or outputs of composite type inverter, saved the cost and the installing space of this device greatly, but and the whole efficiency of lifting device.
Description of drawings
Fig. 1 is a structure principle chart of the present utility model;
Fig. 2 is the utility model generator windings schematic diagram.
Embodiment
As shown in Figure 1, 2, a kind of main frame shaft alternator constant frequency electric supply installation with power converter, comprise and drive coupling arrangement 2 and generator 1, external motive device 3 provides power by driving coupling arrangement 2 for generator 1, at least adopt four groups of stator winding of isolating mutually in described generator 1 inside, wherein three tunnel outputs of generator are connected with three groups of single-phase inverters 4, single-phase inverter 4 is connected with power device by output switch 5, another road is connected with controllable rectifying device 6, and controllable rectifying device 6 links to each other with the storage battery 7 of outside.
The relative prior art maximum of the utility model and to hold a little be at the inner many groups stator winding of isolation mutually that adopt of generator, the system of adopting this structure can save isolating transformer when the output current conversion, quite generator itself be generator be again isolating transformer, save the cost and the installing space of this device greatly, but the lifting efficient that our experiments show that system is more than 5%, and inverter can adapt to 100% unbalance loading output, the wide adaptability of unbalance loading; When actual motion, can reduce the consumption of fuel, reduce maintenance cost, strengthen the validity of power supply supply, reduce labor intensity of operating personnel, use the boats and ships of this device and the noise of vehicle also can suitably reduce.
The utility model surpasses the part of three groups of windings in addition, and this road output can be storage battery power supply through controllable rectifying device, also can realize inversion output when outage.
