Background technology
Because the day of the energy is becoming tight, various electricity-saving appliances emerge in large numbers market.In lighting electricity saving device, there is at present auto-type transformer to transfer the scheme and the thyristor chopper-type scheme of output.But the thyristor chopper-type will produce a large amount of harmonic pollutions when pressure regulation, and therefore most of producers adopt auto-type transformer to transfer the scheme of output.This scheme as shown in Figure 1, among the figure: KM: bypass contactor; KM1:205V exports control contactor, promptly low economize on electricity shelves KM2:195V output control contactor, promptly high economize on electricity shelves; T: transferring the output auto-type transformer is the phase modulation line; RL: load.
This technical scheme is by regulating auto-type transformer secondary coil quantity, reaching the purpose that changes output voltage.On control principle, KM and KM1, KM2 interlocking, KM1 and KM2 interlocking, going into the civil power phase line by the L termination is live wire, and the B point meets load RL, and N is a zero line, and its course of work is as follows:
1., bypass (non-economize on electricity): KM1, KM2 disconnect earlier, adhesive KM again, U
A=U
B, the RL both end voltage equals line voltage;
2., low economize on electricity (under standard civil power 220V, being output as 205V), disconnection KM1, adhesive KM2 more earlier;
3., transfer high economize on electricity (under the standard civil power 220V, being output as 195V) to by hanging down economize on electricity, elder generation disconnection KM1, adhesive KM2 again.
Can find out that from the above voltage-regulation principle and the course of work there is the technological deficiency of the following aspects in this scheme:
1., because the total current I=I of electricity-saving appliance work
R+ I
T, and I
TLess, the bigger electric current I of electric current
RForm the closed-loop path by the B point through RL, thus KM, KM1, KM2 is when switching, and it is big that electric current is flow through in the contact, damages contactor easily, had a strong impact on the stability and the useful life of electricity-saving appliance itself;
2., because when each the switching, load RL must break away from current supply circuit earlier, inserts again, so just caused load RL that the phenomenon of outage is arranged, its power-off time is the time that 2 contactors move.This situation if RL is a lighting load, just causes light emitting source to extinguish easily and restarts, said in the industry of just economizing on electricity " dodging disconnected " phenomenon.This phenomenon is bigger to the damage of light fixture;
3., during voltage-regulation,, when practice, can not be provided with many grades and regulate automatically, seriously reduced the intelligent degree and the applicability of machine because loaded " dodging disconnected " phenomenon and contactor switch current are bigger.

BCElectric current.We suppose that input voltage is the 220V of standard, will press operation, I so under the condition of I=100A
TCurrent value be calculated as follows:
∵U
AC＝220V V
BC＝210V
∴U
AB＝220-210＝10V
