Description
Technical field
The utility model relates to the power energy-saving technology.
Background technology
Existing power-saving technology to genemotor, emphasis all are to utilize genemotor when side circuit is worked, and itself is an engine, also is generator.General method is to utilize genemotor (during the open and close engine) or change load (when lift becomes decline from rising) when speed change, and genemotor can become generating from electricity consumption.Reclaim these electric energy,, feed back to circuit input end then from new integrating frequency and waveform, or the electrical network of subordinate's low pressure, to reach energy-saving effect.This design meeting is very complicated, and is energy-conservation more suitable to heavy-duty motor.If it is then inapplicable concerning low-power machine.
Summary of the invention
The purpose of the utility model is to provide a kind of simple structure, is not stop production living reverse power to reach the single-phase commentaries on classics three-phase energy-saving device of energy-saving effect when rotated in order to reclaim genemotor.
The purpose of the utility model can realize like this, designs a kind of single-phase commentaries on classics three-phase energy-saving device, comprises auto-type transformer and three-phase frequency modulator, and the out-secondary of auto-type transformer is connected with the three-phase frequency modulator.
The utility model can improve conversion efficiency to reach purpose of energy saving.
Description of drawings
Fig. 1 is the schematic diagram of one of the utility model preferred embodiment.
Fig. 2 is the auto-type transformer winding structure figure of one of the utility model preferred embodiment.
Embodiment
Below in conjunction with embodiment the utility model is done further to describe.
A kind of single-phase commentaries on classics three-phase energy-saving device comprises auto-type transformer 1 and three-phase frequency modulator 2, and the out-secondary of auto-type transformer 1 is connected with three-phase frequency modulator 2.
Electric capacity in high efficiency auto-type transformer and the three-phase frequency modulator constitutes a L/C accumulator on circuit, the reverse power of the genemotor that it is just in time promoted the three-phase frequency modulator stores from new use.Auto-type transformer also becomes isolator, and it separates input power supply electric energy and reverse power, reduces by two electric energy collisions and cancels each other to increase power saving capability.
The utility model proposes new auto-type transformer winding method main points: the no-load current of primary coil designs more little well more, and the no-load current of primary coil Cp is below 100mA; Secondary coil is wrapping iron core at internal layer, and primary coil is wrapping secondary coil in outermost.
As shown in Figure 1, a kind of single-phase commentaries on classics three-phase energy-saving device comprises auto-type transformer 1, input termination LVPS S, and voltage can be 110V, 220V or lower.Primary coil Cp senses secondary coil Cs to electric energy, and secondary coil Cs becomes electric energy into high pressure 380V or more high voltage electric energy F output.Storage was on capacitor C after three-phase frequency modulator 2 was sent out the f rectification to high voltage electric energy, and the computer in three-phase frequency modulator 2 becomes three phase mains output again again and promotes motor 3.Three-phase frequency modulator in the present embodiment adopts three commercially available brilliant frequency converters, and model is S350, and power is 2000KW.
Motor M also constantly sends reverse power B when work, from Fig. 1, see the secondary coil Cs of auto-type transformer 1 and the capacitor C in the three-phase frequency modulator 2, on the circuit loop of reverse power B, forms a L/C accumulator.Therefore reverse power B is just stored by secondary coil Cs/ capacitor C again and uses.
Auto-type transformer 1 separates reverse power B and input power supply S, and reverse power B is reverse transformation, just can significantly reduce so they directly liquidate thereby consume mutually.This increases energy-saving effect.
The no-load current of the primary coil Cp of auto-type transformer 1 designs more little well more.This can make the electric energy of input LVPS S almost all store up at primary coil Cp and become magnetic energy F.These magnetic energy F can flow in the iron core of auto-type transformer 1 and the loop of accomplishing magnetic energy F.
Auto-type transformer 1 secondary coil is wrapping iron core at internal layer, and primary coil is wrapping secondary coil in outermost.The magnetic energy F of primary coil Cp can all pass secondary coil Cs like this, and the magnetic energy F output electric energy that alters fully.
Present general auto-type transformer, efficient approximately is between 85%～92%, if rise to 97% of the limit, manufacturing cost and specification requirement are all very high.The utility model proposes new auto-type transformer winding method, is easy to just can produce the auto-type transformer of 98%～99% efficient.The auto-type transformer 1 of the single-phase commentaries on classics three-phase energy-saving of the utility model device does not focus on that selecting for use special material section, phase shaft center of gravity to be placed on becomes the magnetic energy aspect to whole electric energy fully to the method for raising the efficiency.Therefore the auto-type transformer cost of the utility model can be very cheap.
