Description
Technical field
The present invention 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 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, from new integrating frequency and waveform, then feed back to circuit input end, or the electrical network of subordinate's low pressure, to reach energy-saving effect.This design meeting is very complicated, and is applicable to the heavy-duty motor energy saving comparison.If then inapplicable concerning low-power machine.
Summary of the invention
The object of the present invention is to provide a kind of simple structure, is not stop production living reverse power to reach the single-phase three-phase energy-saving device that turns of energy-saving effect in order to reclaim genemotor when rotated.
Purpose of the present invention can realize like this, designs a kind of single-phase three-phase energy-saving device that turns, and 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 present invention can improve conversion efficiency to reach energy-conservation purpose.
Description of drawings
Fig. 1 is the schematic diagram of one of preferred embodiment of the present invention.
Fig. 2 is the auto-type transformer winding structure figure of one of preferred embodiment of the present invention.
Embodiment
The invention will be further described below in conjunction with embodiment.
A kind of single-phase three-phase energy-saving device that turns 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 consists of a L/C accumulator at circuit, and the reverse power of the genemotor that it just in time promotes the three-phase frequency modulator stores from new use.Auto-type transformer also becomes isolator, and it separates input power electric energy and reverse power, reduces by two electric energy collisions and cancels each other to increase power saving capability.
The present invention proposes new auto-type transformer winding method main points: the no-load current of primary coil designs the smaller the betterly, 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 three-phase energy-saving device that turns 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, see the secondary coil Cs of auto-type transformer 1 and the capacitor C in the three-phase frequency modulator 2 from Fig. 1, at L/C accumulator of circuit loop composition of reverse power B.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 S, and reverse power B is reverse transformation, just can greatly 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 the smaller the betterly.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 finishing 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 present invention 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 that the present invention is single-phase to turn three-phase energy-saving device does not focus on that selecting special material section, phase shaft center of gravity to be placed on becomes the magnetic energy aspect fully to whole electric energy to the method for raising the efficiency.Therefore auto-type transformer cost of the present invention can be very cheap.
