Abstract
The utility model relates to a portable multifunction voltage regulator with double voltage class, which mainly uses a controlled silicon to make an electrodeless step-down regulation for power supply voltages. The utility model is a widely used electronic device which regulates light, temperatures and speed for household electrical appliances. The utility model has a power supply plug (1), a conducting wire (2) and a socket which is used for switching on the load R<L>(5) of the household electrical appliances. The inner part of a voltage regulator (3) is provided with a potentiometer W (8) which can regulate the time of charging and discharging a capacitor C (9), and a trigger diode D (10) controls the increase or the decrease of the angle of flow of a triode thyristor SCR (11); output voltages are increased or decreased with the increase or the decrease of the angle of flow. A changing switch K (6) and a fixed resistor (7) which is connected in series can be used for switching for the household electrical appliances of 220V or 110V.
Description
The utility model relates to the stepless supply voltage of turning down of a kind of energy, makes household electrical appliance light modulation, temperature adjustment, the broad-spectrum controllable silicon electronic installation of speed governing.
The common method of electrical equipment pressure regulation is to use transformer, or on circuit series resistor, reactance component, to reach supply voltage is downgraded, the serviceability of corresponding change electrical equipment.The employed component structure of these methods is big, and the energy consumption of itself is bigger.In recent years, be applied industrial with silicon-controlled voltage regulation, and progressively be generalized on the household electrical appliance.The civilian supply voltage of Cai Yonging all over the world has 110 volts and 220 volts not, the household electrical appliance of being made, and it is also corresponding that to be useful on 110 volts or 220 volts other.At present, be used in the controllable silicon step-down voltage regulator of 220 volts of power supplys can not dual-purpose on the electrical equipment of 220 volts of systems and 110 volts electrical equipment of making.Like this, the user to 110 volts of system electrical equipment brings very big inconvenience.
The purpose of this utility model is to provide a kind of 220 volts of step-down regulators on the power supply that are connected to, it not only can be to the household electrical appliance stepless voltage regulation of 220 volts of systems, reach the multi-functional requirement of light modulation, temperature adjustment, speed governing, and can use safely equally on the household electrical appliance of 110 volts of systems.It is in the normal power scope of household electrical appliance, and structure is light and handy, and is easy to use and carry.
The purpose of this utility model is achieved in that and is being generally used for 220 volts of supply voltages are done serial connection one fixed resistance R on the potentiometer W of reduction regulation, the resistance value when its resistance is equivalent to potentiometer W pressure regulation to 110 volt.Change over switch K closes, and connects 220 volts of systems, the resistance R short circuit, and it is 0 o'clock that the stepless high pressure of potentiometer is transferred to resistance, the output maximum voltage is near 220 volts.Change over switch K disconnects, and connects 110 volts systems, the fixed resistance R conducting that is connected in series with potentiometer W, and at this moment to be transferred to resistance be 0 o'clock to the potentiometer stepless voltage regulation, and exporting maximum voltage is 110 volts, and like this, 110 volts of electrical equipment of making have reliable overvoltage protection in the pressure regulation process.
The utility model is because only need be connected in series change over switch K and the fixed resistance that is in parallel on the potentiometer of former 220 volts of voltage regulators, just can realize 110 volts stepless voltage regulation, so be implemented in easily on the same voltage regulator, the power supply that connects 220 volts can be respectively to 220 volts of systems or 110 volts of household electrical appliance stepless voltage regulations of making, therefore speed governing, light modulation and temperature adjustment, can accomplish that again volume is gently little, is convenient to carry.
The concrete structure of utility model is provided by following embodiment and accompanying drawing thereof.
Fig. 1 is the electronic schematic according to the portable pair of voltage gear Multi-functional voltage regulator that the utility model proposes.
Describe in detail according to concrete structure and the operation principle thereof that the utility model proposes below in conjunction with Fig. 1.
This device comprises the latch (1) and the power lead (2) that can connect 220 volts of power supplys, power lead (2) connects the voltage regulator (3) of similar terminal block, be connected to socket aperture (4) on the voltage regulator (3), in order to connect household electrical appliance R 220 volts of systems or 110 volts of systems
L(5).Change over switch K(6) presses 220 volts or 110 volts changing-overs of standard of the household electrical appliance of being connected.When being used for 220 volts of systems during electrical equipment, change over switch K(6) close, fixed resistance R(7) by short circuit, the source current load household electrical appliance R that flows through
L(5), and potentiometer W(8), make capacitor C (9) charging, when the voltage of capacitor C (9) reaches certain value, bidirectional trigger diode D(10) conducting, and make thyristor SCR(11) the discharge of the control utmost point, make thyristor SCR(11) conducting, the load household electrical appliance have immediate current to pass through.During the power supply alternating voltage zero-crossing, thyristor SCR(11) to close, said process circulates again and restarts.Regulator potentiometer W(8) resistance value, it is fast or slow to change capacitor C (9) charging, thereby change the speed that its both end voltage raises or reduces, make diac D(10) do sth. in advance or postpone to trigger, the corresponding thyristor SCR(11 that makes) angle of flow increases or reduces, and output voltage increases or reduces.Just make potentiometer W(8) resistance when strengthening gradually by zero beginning, load household electrical appliance R
L(5) both end voltage reaches the purpose of regulation voltage by lowering gradually near 220 volts.When being used for 110 volts of systems change over switch K(6 during electrical equipment) open potentiometer W(8) with fixed resistance R(7) connect.Fixed resistance R(7) be so selected: when potentiometer W(8) resistance value is zero, fixed resistance R(7) resistance value make thyristor output the electricity is at 110 volts of pressure.At this moment, change over switch K(6) just become 220 volts or 110 volts of two voltage gear change over switches.Make voltage regulator (3) can be used for 220 volts of systems or 110 volts of system household electrical appliance safely and reliably.The utility model is because used electronic component is all less, can satisfy generally to use the household electrical appliance power requirement always and gently urinate in carrying.
Claims (1)
1, thereby can make stepless the turning down of supply voltage make the household electrical appliance light modulation, temperature adjustment, the controllable silicon electronic installation of speed governing, this device has an adjustable potentiometer W (8) that a capacitor C (9) is discharged and recharged, a trigger tube D (a 10) thyristor SCR of control (11) is closed or conducting, it is characterized in that being in series with fixed resistance R (7) on the potentiometer W (8) and can make fixed resistance R (7) work or the change over switch K (6) of cross-over connection short circuit, when change over switch K (6) disconnected, fixed resistance R (7) can make thyristor (11) have to be to the maximum 100 volts of voltages outputs to 120 volts of scopes.
