Abstract
The utility model relates to a multi-voltage diesel-electric set capable of being quickly switched, which is characterized by comprising a large current multi-pole change-over switch S and a generator G. The large current multi-pole change-over switch S is used for directly controlling output windings of the generator G. The output windings are connected in series or in parallel according to the switch. The change-over switch is used for realizing direct external switching of an output voltage so that users can switch voltage as required. The operation is convenient, and the safety performance is high.
Description
Technical field
The utility model belongs to the voltage output device of diesel oil and gasoline generating set, the diesel generating set of the quick conversion of particularly a kind of multivoltage.
Background technology
In the prior art, the line voltage that uses is all according to national standard formulation, each national voltage and frequency have nothing in common with each other, especially country such as U.S., the standard of household electricity and commercial power all has bigger difference, after buying generating set, if the band household electricity just must be bought the generating set of 120/208V, and want industrial electrical equipment, just must select the generating set of 277/480V for use.If just must change the output winding of generating set with industrial generating set band household electrical appliance, general personnel do not have ability to change voluntarily at all, just because of existing generator output voltage is single, cause people very inconvenient when reality is used.
Summary of the invention
The purpose of this utility model is, provides a kind of simple in structure, easy to operate, and multivoltage that can easy switching between two kinds of voltage is the diesel generating set of conversion fast.
The utility model solves the problems of the technologies described above by the following technical programs: a kind of multivoltage is the diesel generating set of conversion fast, it is characterized in that: comprise a multipole change over switch of big electric current and a generator, the multipole change over switch of described big electric current is connected to generator.
The mode of connection of described generator output winding is inner T10, T11, and the direct short circuit of T12 forms the engine neutral point N utmost point, outside T1, T2, T3 be directly as the U of motor, V, the output of W three-phase, T4, T5, T6, T7, T8, these six the end of a thread of T9 are as the controlled change over switch that terminates to.
The utility model multivoltage is the advantage of the diesel generating set of conversion fast: owing to adopt change over switch to realize outside directly switching output voltage, the user is switched voltage as required just, and is easy and simple to handle, safe.
Description of drawings
In conjunction with the embodiments the utility model is described in further detail with reference to the accompanying drawings.
Fig. 1 is the utility model multivoltage circuit theory schematic diagram of the diesel generating set of conversion fast.
Embodiment
See also Fig. 1, the diesel generating set that a kind of multivoltage is changed fast, comprise a multipole change over switch S of big electric current and a generator G, use the multipole change over switch S of big electric current directly to control the mode of connection of generator G output winding, outside winding forms the serial or parallel connection state according to switch, thereby directly influence output line voltage is 240V or 480V, guarantees the voltage conforms instructions for use of output.
In wiring, inner T10, T11, the direct short circuit of T12 forms the engine neutral point N utmost point, outside T1, T2, T3 be directly as the U of motor, V, the output of W three-phase, T4, T5, T6, T7, T8, these six the end of a thread of T9 control the output voltage of generator as the controlled change over switch that terminates to.After connecting the line, if go to the 240V position, then generator output winding is per 2 sets in parallel operation, and after output 240V voltage went to the 480V position, generator windings formed cascaded structure, output 480V voltage.
Claims (2)
