Abstract
The utility model discloses a direct current (DC) output speed-variable and frequency-variable generator set. A diesel engine is respectively connected with a controller, a speed regulator and a generator, the generator is connected with a rectifying inverter, the rectifying inverter is connected with a voltage induction sensor, and the voltage induction sensor is connected with the speed regulator. The DC output speed-variable and frequency-variable generator set has the technical effects that the generator set can directly output 48V DC, so an uninterrupted power supply (UPS) can be omitted for users in the use process, and the cost is saved. The size of the generator set is smaller than that of the traditional generator set, the noise is low, and the energy consumption is low. Simultaneously, the reliable alternating current/direct current (AC/DC) output and single-phase/three-phase selective output are realized. The generator set is the combination result of the efficient permanent magnet technology and the advanced electronic technology.
Description
Technical field
The utility model relates to a kind of speed changing, frequency converting generator set, relates in particular to a kind of direct current output variable speed variable-frequency power generation unit.
Background technique
In telecommunications, move, base station and military project field work, all need little, the lightweight DC electrical source of volume as main with or standby power supply, if with traditional generator set, not only big, Heavy Weight of volume but also oil consumption are high, are not had an optimistic view of by this market always.And a kind of appearance of new DC output variable speed variable-frequency power generation unit can be satisfied the demand of these trade power consumption equipment fully.
Summary of the invention
The purpose of the utility model is to provide a kind of direct current output variable speed variable-frequency power generation unit, and this diesel generating set adopts the speed changing, frequency converting generating, and this mode can help generator set to reduce the influence to environment; No matter be oil consumption aspect or noise aspect; When the user used low load, unit was in slow-speed of revolution operation, and the slow-speed of revolution provides low-power; The slow-speed of revolution also means low noise, low oil consumption (can practice thrift 20% to 30% oil consumption).This generator set can be exported stable 48V VDC through after the commutation inversion of rear end; Three-phase or the single phase alternating current voltage of 50Hz be can also export simultaneously as required, the base station power of domestic and international communications industry and the commonly used or standby power supply of army's communication apparatus are particularly suitable for.
The utility model is realized like this; It comprises diesel engine, controller, speed regulator, generator, rectification adverser, voltage induced sensor; It is characterized in that diesel engine connects controller, speed regulator and generator respectively; Generator connects rectification adverser, and rectification adverser connects the voltage induced sensor, and the voltage induced sensor connects speed regulator.
The technique effect of the utility model is: this generator set can directly be exported the 48V direct current, and the user in use can save ups power for this reason, has practiced thrift cost; This generator set is littler than traditional generator set volume, and noise is low, and energy consumption is low; Have reliable AC/DC output and single-phase/three-phase simultaneously and select output; This generator set is the result that permanent magnetism is technological and advanced electronic technology combines efficiently.
Description of drawings
Fig. 1 is the functional-block diagram of the utility model.
Embodiment
As shown in Figure 1, the utility model realizes that like this diesel engine 1 connects controller 2, speed regulator 3 and generator 4 respectively, and generator 4 connects rectification adverser 5, and rectification adverser 5 connects voltage induced sensor 6, and voltage induced sensor 6 connects speed regulator 2.The unit output voltage is exported direct current 48V after commutation inversion power supply supplies the user directly to use; When the user is in different load conditions; Voltage transducer in the unit passes to the electronic speed regulator of unit with the signal of sensing, thus the rotating speed and the oil consumption of the throttle control diesel engine of speed regulator control diesel engine, when the diesel engine slow-speed of revolution; The generator output LOW voltage; Oil consumption simultaneously and noise are also lower, and unit output low-power satisfies the demand that the user hangs down load.Wherein the speed range of diesel engine is 1000rpm to 3300rpm.
