Description

A kind of multifunctional power saving device

One, technical field

The utility model relates to a kind of battery saving arrangement, and specifically a kind of multifunctional power saving device belongs to electronic technology field.

Two, background technology

Electrical appliance in use owing to the voltage on the house lead in electrical network, electric current along with the variation of time presents periodic variation, this periodically variable voltage, electric current are in the variation that is subjected to industrial interference or electrical network middle impedance and effectively big ripple or burr occur, this voltage, electric current that has ripple or burr is added in and damages electrical equipment on the various electrical equipment easily, also can make suddenly big or suddenly small the flogging a dead horse of voltage, electric current on the electrical equipment, both wasted valuable electric power resource, and also can make the reading on the ammeter inconsistent with the actual electric energy that uses.Particularly electrical equipment is being started working this in a flash, often produces very big surge pulse current, and this surge pulse current is several times even tens times a height of electrical equipment operate as normal, the easiest household electrical appliance that burn out.

At present, though the protector for household electrical appliances that uses on the market has the effect of voltage stabilizing and current stabilization, the manufacturing cost height, the electric energy of consumption is bigger, does not have electricity-saving function.On the other hand, the ifs circuit this protector in the back powered-down voluntarily that breaks down, fail safe is poor.Can not recover automatically after the troubleshooting, also need the people to restart, no auto restore facility.

Three, utility model content

The utility model is to have above defective and propose a kind of new technical scheme on circuit structure design in order to solve existing circuit protection device.

The technical scheme that the designing technique defective of its existence of solving the utility model is adopted is: a kind of multifunctional power saving device, it is made up of housing and electronic circuit, be provided with plug and jack and be electrically connected with the electronic circuit two ends on housing, electronic circuit is by an overvoltage crowbar; One current foldback circuit; One filter circuit and a working indicating are formed.

Overvoltage crowbar is by fuse F and piezo-resistance R _VComposition is in series; Current foldback circuit is by thermistor R _TAnd resistance R ₁Composition is in series; Filter circuit is by series capacitance C ₁, C ₂With shunt capacitance C ₃, C ₄Form, at series capacitance C ₁An end and shunt capacitance C ₃Or C ₄An end between be connected to diode D ₁, the other end links together, and is electrically connected with the other end of overvoltage crowbar; Working indicating is by resistance R ₂With light-emitting diode D ₂Be composed in series, two ends are connected the two ends of shunt capacitance; Be connected series capacitance C in the other end and the filter circuit between fuse F and the piezo-resistance Rv tie point in one end of current foldback circuit and the overvoltage crowbar ₁With diode D ₁Continuous contact is electrically connected; Two of working indicating terminates at shunt capacitance C ₃, C ₄Two ends; The two ends of overvoltage crowbar and the jack on the housing are electrically connected, and the two ends of filter circuit and the plug on the housing are electrically connected.

Set filter circuit is a π type filter circuit between current foldback circuit and working indicating.

The advantage that the utility model had is: circuit structure is simple, and is cheap for manufacturing cost, and continuously useful life can be for 6 years, and is easy for installation, safe in utilization, has the effect of voltage stabilizing, current stabilization, also has the function of economize on electricity.Inductive circuit had power saving rate about 28%, as electrical equipment such as air-conditioning, refrigerator, television set, computer, washing machine, electric heater, photocopiers.Capacitive electrical equipment power saving rate about 23%, is had the effect of economize on electricity equally for illumination class light fixture, can be widely used in family and public place and use, power savings is fairly obvious.

Five, embodiment

Fuse F and piezo-resistance Rv are cascaded, constitute overvoltage crowbar (4), the jack (2) on the termination at two ends and the housing (1) and being electrically connected.Thermistor R _TWith resistance R ₁Series connection mutually constitutes current foldback circuit (5); Capacitor C ₁, C ₂Be in series capacitor C ₃, C ₄Be in parallel series capacitance C ₂The other end and shunt capacitance C ₃, C ₄An end be connected, at series capacitance C ₁The other end and shunt capacitance C ₃, C ₄The other end between be connected to diode D ₁, constitute filter circuit (6).The close thermistor R of current foldback circuit (5) _TAn end and the tie point of fuse F and piezo-resistance Rv be electrically connected capacitor C in the other end and the filter circuit (6) ₁With diode D ₁Tie point be electrically connected, at shunt capacitance C ₃, C ₄Two ends between be connected to by resistance R 2 and light-emitting diode D ₂The working indicating that is composed in series (7).The two ends of filter circuit (6) are electrically connected with the plug (3) that is fixed on the housing (1).Also can exchange the input of this entire circuit, output two ends mutually with jack (2) with plug (3) and be connected as required.

Overvoltage crowbar (4) is made up of fuse F and piezo-resistance Rv; the effect of the instantaneous interference Finite Amplitude slicing that electrical network is produced; the surge pulse that alternating current is produced has inhibitory action; because of certain factor generation misphase voltage becomes 380V by 220V, fusing fuse F can effectively protect the intact of personal safety and equipment.

Current foldback circuit (5) is by thermistor R _TAnd resistance R ₁Be composed in series, at ordinary times, thermistor R _TResistance value very little, in pressure drop, produce much influences can not for circuit.When line short or circuit occurred leading normal fault, electric current sharply increased at short notice in the loop, and heating temp surpasses Curie point, thermistor R _TResistance value increase to more than the megaohm, make most of voltage drop at thermistor R _TTwo ends, thus protected human body and electric equipment to stand intact.In current foldback circuit (5), whatsoever reason is as long as ambient temperature surpasses 80 ℃, and this circuit will quit work, thereby cuts off the electric current that flows to household electrical appliance, has protected electric equipment.

Filter circuit (6) is by capacitor C ₁, C ₂Be together in series capacitor C ₃, C ₄Be connected in parallel, between an end of end of series capacitance and shunt capacitance, be connected to a diode D ₁The effect of this circuit is the interference of filtering oscillator signal to electrical network, also suppressed high-frequency harmonic (especially triple-frequency harmonics) content and caused severe contamination electrical network, destroy the balance of three phase mains, cause single-phase asynchronous motor heating aggravation, efficient reduces, and torque produces fluctuation must influence appliance life.Moreover the neutral line (zero line) electric current stack excess load, the lighter's tripping operation burns out fuse F, and weight person can cause accidents such as fire.

Working indicating (7) is by resistance R ₂With light-emitting diode D ₂Be composed in series diode D ₂Luminous explanation line work is normal, otherwise unusual.

During use, the utility model is installed in series for a long time on the ammeter and the circuit between the household electrical appliance of electrical network house lead in, has tangible power savings, and useful life continuously can be for 6 years.
