The present invention realizes by following scheme: it comprises ∏ mode filter, Transient Voltage Suppressor, dual pressurizer, clamper, current inductor, rectification circuit, alignment circuit, automatic control circuit, trigger, major loop composition.
A kind of single phase sewing machine electricity-saving appliance of the present invention is characterized in that the ∏ mode filter is in parallel with electrical network, and Transient Voltage Suppressor links to each other with dual pressurizer the clamp inhibition is carried out in the output of ∏ mode filter, and biasing circuit triggers VD1 work simultaneously.
The current inductor T that the present invention is used, R4-R9, C9-C10, W1, D4, VD4 constitutes rectification circuit, adopt halfwave rectifier filtering, control voltage with voltage-stabiliser tube afterwards, when the load load increases, when electric current strengthens, current inductor produces high voltage on resistance, behind the rectifying and wave-filtering, when this voltage rising certain value, voltage-stabiliser tube is punctured, give the transistor base bias current of back, the high more base current that provides of voltage is big more, the triode ducting capacity is strong more, has constituted automatic control circuit, triggers major loop, automatically regulate the watt level of sewing machine, reach purpose of saving.
Above-mentioned automatic control circuit is made of Q, D1-D4, R11-R12, and R13, VD3 constitute circuits for triggering, and VD2, C1-C3, R13-R14, VD3, W2 connect and compose major loop and alignment circuit.
Tracking velocity simple in structure, easy to use, automatic that the present invention has is fast, saves energy, protection equipment, energy-conservation more than 45%, can stop wink stream to the long-term pollution of power supply, and avoids the generation of transition surge, makes electric current reach relative equilibrium.
Description of drawings:
Fig. 1 has represented embodiment of the invention block diagram.
Fig. 2 is an electrical schematic diagram of the present invention.
Embodiment:
Do further below in conjunction with accompanying drawing and to elaborate.
The present invention is made up of ∏ mode filter, Transient Voltage Suppressor, dual pressurizer, clamper, current inductor, rectification circuit, alignment circuit, automatic control circuit, trigger, major loop as shown in Figure 1.
Most preferred embodiment of the present invention is: in the circuit, inductance L 1-L2 and C1-C3 form the ∏ mode filter as shown in Figure 2.Carry out filtering by filter, allow the composition of given frequency pass through by the composition that stops other frequency.Transient Voltage Suppressor is made up of piezo-resistance, and piezo-resistance and TVP pipe T1-T3 constitute dual pressurizer.Clamper suppression protective circuit comprises two-way TVP pipe T1-T3; the quick clamping voltage of they common formations suppresses wink stream protective circuit, is characterized in that transient power is big; clamping voltage is enough low and dispersed little, can suppress not high and wink that generation speed is very fast of those peak values stream.Controllable silicon obtains the control electrode current by biasing resistor simultaneously, with the less bigger unstable voltage of power control, forms dual overvoltage protection with the two-way TVP pipe of piezo-resistance.Current inductor T, R4-R9, C9-C10, W1, D4, VD4 constitute rectification circuit, automatic control circuit is made of Q, D1-D4, R11-R12, R13, VD3 constitute circuits for triggering, and VD2, C1-C3, R13-R14, VD3, W2 connect and compose major loop and alignment circuit.Adopt halfwave rectifier filtering, afterwards with voltage-stabiliser tube VD4 control voltage, when the load load increases, when electric current strengthened, current inductor T produced high voltage on resistance, behind the rectifying and wave-filtering, when this voltage rising certain value, voltage-stabiliser tube VD4 is punctured, give the triode Q base bias current of back, the high more Q base current that provides of voltage is big more, and triode Q ducting capacity is strong more, constituted automatic control circuit, trigger major loop, the watt level of regulating sewing machine automatically reaches purpose of saving.
