Abstract
The utility model relates to an ideal power saving life prolonging protector for household electric appliances which is composed of an over-voltage protection circuit (1), a rectifying voltage stabilizing circuit (2), a delay circuit (3), a pulse forming circuit (4) and a control circuit (5) and has the functions of power save, lifetime extension, over-voltage protection, etc. The utility model has the advantages of small size, convenient operation and repair, and low cost. The power saving life prolonging protector of the utility model is suitable for all the families.
Description
The utility model relates to a kind of family non-electricity protector, the energy-saving, service life prolonged protector of particularly a kind of household electrical appliances.
Existing household electrical appliance, as the damage of aspects such as television set, recorder, electric fan, washing machine, occur in the moment of power connection or disconnection mostly, because this being switched on or switched off in a flash, can produce stronger impulse current, damage electric equipment products first or reduce useful life; Second cause energy loss.In addition, invade the 220V electrical network once in a while,, all easily cause large-area electric equipment products to damage as thunder and lightning, 380V power electricity etc. for being higher than 250V voltage.At present, the tame non-electricity protector that occurs on the market, function singleness has only overvoltage protection, and does not have energy-saving, service life prolonged function.The function that has is more complete, but need to adopt special-purpose complicated machinery device to finish, and keeps in repair very inconveniently, and the mechanical device make and break contact is many, and reliability of products is poor.
The purpose of this utility model is to provide a kind of making simple, use, easy to maintenance, the energy-saving, service life prolonged protector of the household electrical appliances that function is more complete.
The utility model is done in such a way that it is made up of overvoltage crowbar, regulator rectifier circuit, delay circuit, pulse shaping circuit and control circuit.Overvoltage crowbar is made up of quick fuse protective tube and piezo-resistance.Regulator rectifier circuit is made up of rectifier diode, resistance and voltage stabilizing didoe.Delay circuit is made up of resistance, electrochemical capacitor and transistor.Pulse shaping circuit is made up of electric capacity, unijunction transistor, resistance.Control circuit is made up of controllable silicon.
Below in conjunction with accompanying drawing and enforcement thereof one the example the utility model is described in further detail.
Fig. 1 is a block diagram of the present utility model.
Fig. 2 is an electrical schematic diagram of the present utility model.
The utility model model machine is adjusted after a lot of repetition and is tested, and listens to user's reflection, and its comparatively desirable embodiment as shown in the figure.It is made up of overvoltage crowbar ［ 1 ］, regulator rectifier circuit ［ 2 ］, delay circuit ［ 3 ］, pulse shaping circuit ［ 4 ］ and control circuit ［ 5 ］.Overvoltage crowbar ［ 1 ］ is made of quick fuse protective tube BX and piezo-resistance RV; When line voltage surpassed 260V or has thunder and lightning to scurry into, the RV resistance reduced rapidly and makes the BX quick-break, plays the overvoltage protection effect.Regulator rectifier circuit ［ 2 ］ is made of rectifier diode D1～D4, resistance R 1 and voltage stabilizing didoe D5; Controllable silicon needs direct voltage directly to be supplied with by rectification circuit, and the direct voltage that time-delay, circuits for triggering need is by the R1 step-down, and D5 is stable, and the back is supplied with.Delay circuit ［ 4 ］ is made of resistance R 2, R3, R4, electrochemical capacitor C1, transistor Q1; When K was closed, electric current charged to C1 by R2, and along with the continuous rising of C1 both end voltage, Q1 progresses into conducting state by cut-off state, changed the numerical value of R2C1, can change start momentary load both end voltage by zero transit time to 220V; When K is become when disconnecting by closure, C1 will pass through R3, Q1, Q2, R6 discharge, changes the resistance of R3, variable shutdown momentary load both end voltage by 220V to zero transit time; C1 discharged to SCR when isolating diode D6 can prevent the power supply zero passage, destroyed the operating state of SCR.Pulse shaping circuit ［ 4 ］ is made of capacitor C 2 unijunction transistor Q2 resistance R 5, R6; This is a typical unijunction transistor relaxation oscillator, and pulse signal is the b1 utmost point output by Q2.Control circuit ［ 5 ］ is made of controllable silicon SCR; The angle of flow of SCR is subjected to the control of pulse signal, thus control load RL two ends variation of AC voltage.
The input voltage of the appended circuit design of the utility model is 160V～250V, 50HZ, load capacity 150W; The parameter of appropriate change controllable silicon and rectifier diode also can change carrying load ability.
