Description
Technical field
This utility model relates to energy-saving appliance field, particularly relates to a kind of motor magnetic circuit and controls efficient energy-saving device.
Background technology
The energy-saving appliance of existing market has silicon-controlled voltage regulation energy-saving appliance, the series of products such as converter energy-saving appliance are using, although silicon-controlled voltage regulation energy-saving appliance can be energy-conservation, but it has certain defect to be exactly that electrical equipment is produced serious influence by wave distortion, current converter energy-saving appliance be it has been recognized that a kind of Practical energy-saving device.
But converter there is also some shortcomings, current middle-size and small-size converter, majority is the control mode using PWM (pulsewidth modulation).Its carrier frequency is about thousand of to tens KHz, this allows for normal asynchronous stator winding to bear the highest voltage build-up rate, be equivalent to normal asynchronous is applied the surge voltage that steepness is the biggest, make the turn-to-turn insulation of normal asynchronous bear the harshest test.It addition, the rectangle copped wave surge voltage produced by PWM converter is superimposed upon on normal asynchronous working voltage, can constitute a threat to the insulation against ground of normal asynchronous, insulation against ground can accelerated ageing under the repeated stock of high pressure.
Actually converter is also the loss having self, and dominant loss is on module I GBT, and the fastest power consumption of frequency more high switching speed is the biggest.
Utility model content
For the problem of shortcomings and deficiencies in prior art; the utility model proposes a kind of motor magnetic circuit and control efficient energy-saving device, by being combined with converter, improve and protect the performance of converter; further increase the energy-saving effect of converter, it is achieved energy-efficient purpose.
This utility model solves its technical problem and be the technical scheme is that
A kind of motor magnetic circuit controls efficient energy-saving device, including motor, converter, magnetic circuit coil and magnetic circuit control circuit, described magnetic circuit coil is divided into primary and secondary, motor to connect with converter, again with the primary series of magnetic circuit coil, the secondary of magnetic circuit coil is connected with magnetic circuit control circuit.
Further, described motor is monophase machine or three phase electric machine.
Further, described converter is single-phase converter or three phase converter.
Further, it is provided with reference current voltage inside described magnetic circuit control circuit.
This utility model has the advantages that this utility model is adjusted current of electric size by regulation magnetic circuit coil magnetic flux size, and it can reduce reactive loss, makes motor be operated in best power configuration status.And this utility model has circuit structure simply, use electronic component few, it is simple to the advantage of installation.
Accompanying drawing explanation
Fig. 1 is this utility model circuit diagram for three phase electric machine；
Fig. 2 is this utility model circuit diagram for monophase machine.
Detailed description of the invention
Below in conjunction with specific embodiment, this utility model is expanded on further.Should be understood that these embodiments are merely to illustrate this utility model rather than limit scope of the present utility model.In addition, it is to be understood that after having read the content that this utility model is lectured, this utility model can be made various changes or modifications by those skilled in the art, and these equivalent form of values fall within the application appended claims limited range equally.
As it can be seen, a kind of motor magnetic circuit controls efficient energy-saving device, including motor, converter, magnetic circuit coil and magnetic circuit control circuit, described magnetic circuit coil is divided into primary and secondary, motor is connected with converter, then with the primary series of magnetic circuit coil, the secondary of magnetic circuit coil is connected with magnetic circuit control circuit.
Further, described motor is monophase machine or three phase electric machine.
Further, described converter is single-phase converter or three phase converter.
Further, it is provided with reference current voltage inside described magnetic circuit control circuit.
Specifically, as shown in Figure 1,380 volts of alternating currents of three-phase enter the primary of B1, B2, B3 magnetic circuit coil through A, B, C, then from primary a, b, c output, but during motor work secondary together with time corresponding faradic current voltage, and send into magnetic circuit control circuit, it is provided with reference current voltage inside magnetic circuit control circuit, compares with the signal of secondary input.When electric motor starting, motor is in work with the least electric current, but the primary current of magnetic circuit control coil can increase when motor has load, secondary also can increase accordingly, the current and voltage signals of secondary induction is input to magnetic circuit control circuit, compared with secondary current input signal voltage by internal reference current/voltage, thus be adjusted the size of magnetic circuit coil magnetic flux to be adjusted current of electric.
Described a kind of motor magnetic circuit controls efficient energy-saving device and utilizes electromagnetism induction reactance principle, electromagnetism magnetic flux is to change current of electric size, input and output are all sinusoidal wave, without other any clutter, radiationless, environmental protection power supply, it can reduce reactive loss can make motor be operated in best power configuration status, along with the size of motor load can change the magnetic flux of magnetic circuit to mate motor load.
This utility model can carry out passive configuration; internal loss can be down to almost nil power consumption, if being matched to optimum state to can save energy 50%, is combined the performance that i.e. can improve and protect converter with converter; converter energy-saving effect can be made to improve further, it is achieved energy-efficient purpose.This utility model circuit structure is simple, uses electronic component few, it is simple to install.
