Description
Technical field
The utility model relates to energy-saving circuit technical field, specifically belongs to one and falls stream energy-saving protector.
Background technology
Existing household electrical appliance or electricity energy saver in equipment, mainly adopt frequency converter to carry out energy-conservation.Not absolute but frequency converter is energy-conservation, itself wants electricity consumption lossy, frequency conversion is main is can be to asynchronous motor drive, some equipment motor has been joined greatly its electricity used, and just how still power factor is low, that is to say electricity wasted by motor, can be energy-conservation so can improve power factor with frequency conversion.But be mainly can play a role for perceptual electrical equipment; But just can not control for resistive electrical equipment and capacitive electrical equipment.
Utility model content
The purpose of this utility model has been to provide one and has fallen stream energy-saving protector; the deficiencies in the prior art are overcome; circuit design is reasonable; by controllable silicon, control circuit and protective circuit composition, current circuit falls; then series rectifier circuit is connected power consumption equipment afterwards with inverter circuit; by the electric current in circuit is reduced, voltage is constant; reach and reduce circuit loss; protective circuit in circuit simultaneously; can effectively control and fall current circuit; current break, protective circuit device, the safety and reliability of assurance power consumption equipment.
The technical solution adopted in the utility model is as follows:
Stream energy-saving protector falls in one; comprise and fall current circuit, rectification circuit and inverter circuit; the described current circuit one end that falls connects power output end; the other end is series rectifier circuit and inverter circuit successively; connect power consumption equipment by inverter circuit out-put supply end, described falls current circuit bag by three-line, and two circuits are by controllable silicon in serial connection current control circuit and protective circuit; article two, in circuit, protective circuit and current control circuit are connected, and are all connected with another circuit simultaneously.
Described fall current circuit to connect current output terminal voltage be 380V50Hz sine wave alternating current, source current is still 380V50Hz sine wave alternating current by falling output current voltage after current circuit.
Compared with the prior art, the beneficial effects of the utility model are as follows:
The utility model falls current circuit by controllable silicon, control circuit and protective circuit composition; then series rectifier circuit is connected power consumption equipment afterwards with inverter circuit; by the electric current in circuit is reduced, voltage is constant; reach and reduce circuit loss; protective circuit in circuit, can effectively control and fall current circuit, current break simultaneously; protective circuit device, the safety and reliability of assurance power consumption equipment.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Referring to accompanying drawing; stream energy-saving protector falls in one; comprise and fall current circuit 1, rectification circuit 2 and inverter circuit 3; fall current circuit 1 one end and connect power output end; described fall current circuit 1 to connect power output end voltage be 380V50Hz sine wave alternating current, source current is still 380V50Hz sine wave alternating current by falling output current voltage after current circuit 1.Current circuit 1 other end series rectifier circuit 2 and inverter circuit 3 successively falls; connect power consumption equipment 4 by inverter circuit out-put supply end; described falls current circuit bag by three-line; article two, circuit is by controllable silicon 101 series current control circuits 102 and protective circuit 103; article two, in circuit, protective circuit 103 and current control circuit 102 are connected, and are all connected with another circuit simultaneously.In the present invention, fall after current circuit need to connect rectification circuit and inverter circuit and just can reach energy-conserving action, be directly connected power consumption equipment if do not connect rectification circuit with inverter circuit, can only there is defencive function, do not reach energy-conserving action.
