Aforesaid electricity-saving appliance is characterized in that diode D
2Two ends also connect by capacitor C
2And resistance R
2The resistance-capacitance circuit that is composed in series.
The utility model compared with prior art has tangible advantage and good effect, it is owing to adopt technique scheme, eliminated noise, improve the contactor time-delay and discharged frequency, avoided the interval 10 seconds ability adhesive of existing like product required time once, promptly 360 times/hour, can only be applicable to the shortcomings such as occasion use of uniterrupted duty.Electricity-saving appliance of the present utility model can be designed into kind adhesive in 6 seconds once at interval with required time, promptly 600 times/hour, applicable to switching frequency less demanding in, the occasion of uniterrupted duty uses, it is general that operating voltage exchanges 220 volts and 380 volts, this quiet electricity economizer element is few, simple in structure, good reliability.
Below in conjunction with accompanying drawing and preferred embodiment to concrete structure, feature and effect according to the quiet electricity economizer that the utility model proposes, describe in detail as after.
Fig. 1 is circuit theory diagrams of the present utility model.
