Description
The utility model relates to a kind of making of electronic speed regulation voltage regulator.
Existing regulator of fan has two kinds, and one is reactance step speed regulation device; It two is a controllable silicon electronic stepless speed regulation device.
Reactance step speed regulation device is by the different taps of connecting reactor, the voltage that changes the fan electromotor two ends.Reactor generally is made up of silicon steel sheet, enamel insulated round copper wire and other auxiliary material.The shortcoming of this speed regulator is: volume is big, deal is heavy, cost of manufacture is high; When electric current passes through coil, produce certain voltage drop in the coil, reactive loss is bigger, is generally 7-10W; It is few to regulate the shelves number, still has very big air quantity at deep low gear; Because directly connecting with load in the contact, can't avoid spark phenomenon during switching; In addition, because its volume is big, the heat radiation that power consumption causes is many, can't be installed in the body of wall of building or family room, thereby influence the clean and tidy and attractive in appearance of body of wall.
Electronic components such as the potentiometer that controllable silicon electronic stepless speed regulation device employing controllable silicon, fixed carbon resister are made, bidirectional diode.By changing the silicon controlled control voltage and the silicon controlled angle of flow, control the operating voltage and the rotating speed of fan electromotor, thereby reach the speed governing purpose.The shortcoming of this speed regulator is: fixed carbon resister very easily weares and teares, and reliability is relatively poor; Because between metal and the carbon film is that metal contacts with nonmetal, can not block very tightly, and carbon film is under the function of current, and the variation of resistivity will take place for self, causes the speed governing poor stability also often to disturb other electrical equipment with high order harmonic component; Because the silicon controlled angle of flow and motor speed are complicated non-linear relations, the time lag that the electromechanical properties of electric fan causes during speed governing makes this advantage of stepless speed regulation generally can only be used for closed-loop system, and electric fan is an open cycle system, so when using, revise repeatedly several times and just can obtain suitable wind speed.
The purpose of this utility model is to overcome the problem that above-mentioned two kinds of speed regulators exist, provide a kind of miniature, low in energy consumption, good stability, the life-span is long, cost is low, regulate the speed and pressure-regulating device of shelves number fan electromotor many, easy to use, and this speed and pressure-regulating device also is suitable for regulating the operating voltage of household electrical appliance such as incandescent lamp.
The technical solution of the utility model solves as follows: in order to overcome the shortcoming of reactance speed regulator, the utility model has adopted controllable silicon phase-shifting chopped waves circuit to carry out the electronic speed regulation pressure regulation, the radio frequency interference that has adopted electric capacity, inductance to form in circuit suppresses network, and the pulse signal that produces when preventing controllable silicon work disturbs other household electrical appliance.In order to overcome the shortcoming of controllable silicon electronic stepless speed regulation device, the utility model adopt by formula digital display code switch combine with controllable silicon phase-shifting chopped waves circuit carry out electronic step speed-controlled, pressing formula digital display code switch inside, the contact is that the metal contact contacts with metal film.Each digital corresponding different contact that digital switch shows, each contact some fixed resistors of connecting, the resistance value differences of the different series connection in contact.The fixed resistor of connecting with the contact is used for regulating the silicon controlled angle of flow, like this, presses by the coding on the formula digital display code switch with regard to the adjustable fan rotating speed of motor.
The utility model compared with prior art has following advantage:
1, compares with the used fixed carbon resister of controllable silicon stepless speed regulation stronger anti-wear performance and excellent contact performance are arranged; 2, directly do not connect with load in the contact, do not have spark phenomenon; What 3, connect with the contact is fixed resistor, and speed adjustable range is big and more convenient, need not to resemble the stepless speed adjusting gear to revise repeatedly; 4, cost of manufacture is low, power consumption is little, is generally about 0.025mw; 5, in light weight, volume is little, can be installed among the body of wall of building or family room, and can make multi-joint form; 6, owing to having adopted radio frequency to suppress network, minimum to the interference of other household electrical appliance.
Below in conjunction with accompanying drawing the most preferred embodiment by formula digital display speed and pressure-regulating device is elaborated, it is more clear that details of the present utility model will become.This embodiment is illustrational example, and the utility model is not limited to this embodiment.In the accompanying drawing:
