Specific embodiment
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely describe.
Fig. 1～2 are referred to, in this utility model embodiment, a kind of quick regulated power supply, 1) by autotransformer
Circle draws wiring, connects a flat copper coin, spaced apart to have another flat copper coin.As shown in figure 1, two flat boards top has the 3rd
Copper coin, there is thereon insulated connecting rod, and there is a spring upwards at connecting rod middle part, keeps three copper coin Hu Bu UNICOMs.Connecting rod bottom connects one
Iron pan, iron pan is presented herein below electric magnet.The break-make of electric magnet can be controlled by panel.When electric magnet disconnects, spring pushes up company
Bar, circuit disconnects；When the solenoid is energized, electromagnetic actuation iron pan, three copper coins are connected with each other, circuit turn-on.For description side
Just, it is called " T connections ".
2) the m number of turn is selected from the coil of autotransformer carry out T with power input and be connected；From autotransformer
The n number of turn is selected on coil carry out T with outfan and be connected.If total number of turns is N, when input voltage is U1, input connects l circles,
During output connection kth circle, output voltage U2 is equal to k U1/l.
3) voltage stabilizing process, first setting output target voltage U0 and adjustment threshold values Δ U.The voltage stabilizing process for just having started is detection
Input voltage U1, calculates k, l value, determines that i values (1≤i≤m) connect i, j with j values (1≤j≤n) control, exports U2=U0.
Manostat after startup, as | U2-U0 |>During Δ U, new j2 values are calculated, then perform closure j2, be then turned off j, complete logical j
To the switching of logical j2.If i needs to change to i+p, i+1 need to be first changed to, then i+2 ... ... is until being switched to i+p.
4) motor function of step-down start：Motor starting current is often 3 to 6 times of rated current, as motor turns
Increase this electric current of speed is gradually fallen back to below motor rated current.In order to bear the impact of starting current, this causes to be equipped with
The capacity of manostat need to be 3 to 6 times of motor rated power, waste many capacity.Motor can be made 1/2,
Actuating motor under 2/3,3/4 grade voltage, corresponding starting current also reduces, and reduces the waste of capacity.In outfan from 1/
The 2N numbers of turn start the number of turn at regular intervals and are gradually transitions conventional number of turn group.Zero load, underloading, middle load and heavy duty according to motor
Situation progressively go back up to rated voltage from low pressure using programme-control voltage.
In FIG, copper coin 1, insulated connecting rod 4, the integral motion of iron plate 8.9 electric magnet.When electric magnet 9 is not powered on, bullet
Spring 7 above pushes away connecting rod 4, and copper coin 2 is not turned on copper coin 3；When electric magnet 9 is powered, connecting rod 4 is attracted to down, copper coin 1 and copper coin 2,
Copper coin 3 is fitted simultaneously, and (3 turn on copper coin 2 with copper coin.
In Fig. 2, input " T connections " organizes 13, totally 10 line, is connected in transformator 14 respectively, and 175,183,190,197,204,
On 211,218,225,232 and 240 circles.Totally 240 circle of autotransformer 14.Output " T connections " group 15, totally 25 line, has 20 lines to connect
As the conventional group of output on the 221-240 circles of transformator；There are 5 lines to be connected in conduct on 120,140,160,180 and 200 circles respectively
Motor low voltage starting group.
When for stablizing 50Hz, during 220V voltages, range of regulation such as following table.
When input voltage is in the range of 160～239,220V can be stably exported, Δ U can use 0.7V.Now, voltage stabilizing
Precision is 220 ± 0.7V, i.e., 220 ± 0.3%, about improves 10 times than 220 ± 3% precision of carbon brush autotransformer.
The manostat response time is estimated, including detection U1 (10ms), and processor calculates the time<1ms (ignores), closes J2
(10ms) cycle (20ms), point J (10ms), operation one cycle (20ms), are run, U1 ... is detected, reaction time is approximately 70ms.
Response speed about than carbon brush autotransformer cycle 1s improves 10 times.
When input for 220 volts when, motor low voltage starting wiring group, can make voltage Jing 110,128,147,165,183V mistakes
Cross to 220v rated voltages, complete the low voltage starting of motor.
It is obvious to a person skilled in the art that this utility model is not limited to the details of above-mentioned one exemplary embodiment, and
And in the case of without departing substantially from spirit or essential attributes of the present utility model, can in other specific forms realize that this practicality is new
