Description
Affiliated technical field
The utility model is a kind of power intelligent energy-saving electric appliance that can change the voltage output frequency, cut down the consumption of energy.
Background technology
Motor be according to equipment at full capacity power come type selecting, and generally all can not oepration at full load during machine operation, as blower fan, water pump, compressor etc.When needing power-equipment that less air quantity, flow, pressure are provided, deep bead be adjusted or choke valve is controlled, but motor speed is constant.The energy that consumes when motor start-up and braking is bigger, and the wear rate of machine components is higher.Adopt frequency control to change motor speed, frequency converter is by to voltage, the isoparametric control of frequency, realize motor softly stop, soft, the voltge surge when having avoided starting reduces motor wearing and tearing and failure rate, prolongs motor useful life.According to fluid mechanics principle, the shaft power of motor is directly proportional with the cube of rotating speed, if motor is when 80% of rated speed is moved, the power of its consumption is (80%) of rated power in theory
3, promptly 51.2%.The power intelligent energy-saving electric appliance adopts conversion method to constitute frequency conversion speed-adjusting system, and control flow, pressure reach purpose of energy saving.
Summary of the invention
The purpose of this utility model is to provide a kind of power intelligent energy-saving electric appliance, can reduce the operating mode loss, prolongs motor useful life.
The technical scheme that its technical problem that solves the utility model adopts is: the power intelligent energy-saving electric appliance is made up of bridge rectifier, charging circuit, filter circuit, resonant circuit, braking circuit, work frequency circuit, inverter circuit, electric group controller.Bridge rectifier is in parallel with filter circuit by charging circuit, and resonant circuit suppresses circuit resonance, and braking circuit is in parallel with filter circuit, and inverter circuit is in parallel with braking circuit, electric group controller output signal control inverter circuit and braking circuit; Wherein, bridge rectifier is made up of 6 diodes, charging circuit is composed in parallel by 1 resistance and 1 relay, filter circuit is made up of 2 electric capacity and 2 resistance, resonant circuit is made up of 1 electric capacity and 1 reactor, braking circuit is made up of 1 resistance and 1 thyristor, and inverter circuit is made up of 6 thyristors.Alternating current is input to the power electricity-saving appliance, through the bridge rectifier rectification, becomes pulse direct current; Charging current was bigger when electricity-saving appliance started, and in charging resistor of bridge rectifier output series connection, absorbed charging current, prevented that rectification circuit from damaging; Charging resistor relay in parallel, when the power intelligent energy-saving electric appliance normally moved, relay was connected, and the charging resistor short circuit reduces circuit loss; Filtered electrical routing capacitance and parallel resistor are formed, and what rectification circuit was exported is pulse direct current, when electric capacity arrives in first pulse, be full of very soon, charging voltage equals crest value of impulse voltage, treats that the voltage on the electric capacity will be by index law to load discharge after this pulse in the past; When the capacitance discharges process is carried out, second pulse arrives, the discharge process halfway is forced to stop, and on the basis that is terminated the residual voltage that discharge the time stored, be full of once more by second pulse, charging voltage still equals the peak value of pulse voltage, treat this pulse in the past after, the voltage on the electric capacity again will be by index law to load discharge, utilize the charge-discharge characteristic of electric capacity, make pulse voltage after the rectification become relatively galvanic current and press; Electric energy with electric capacity parallel resistor absorption electric capacity can prevent that the capacitance discharges electric current is excessive, and electric elements in parallel are with it caused damage; Resonant circuit is made up of electric capacity and reactor, suppresses the input current resonance; Braking circuit is composed in series by resistance and thyristor, and when power-equipment was shut down or braked, controller sent signal, makes the thyristor conducting, and brake resistance absorbs the energy that feeds back in the inverter circuit; Controller sends signal according to the power-equipment running status, and the break-make of thyristor in the control inverter circuit makes electricity-saving appliance export the alternating current of controllable frequency.
The beneficial effects of the utility model are, can control flow, pressure, and the alternating current of output controllable frequency cuts down the consumption of energy, and reaches the purpose of adjusting.
