In order to achieve the above object, the utility model comprises by triple line L1, L2, the input that L3 and center line N form, be connected to triple line L1, L2, the three-phase coil of the single-circuit transformer T that on the L3 each is in series by three groups of coils, be connected the three-phase coil of single-circuit transformer T and the three-phase normally opened contact of the three-phase ac contactor KM4 between the center line N, be connected in parallel on triple line L1 respectively, L2, the three-phase normally opened contact of three-phase ac contactor KM1 on the L3, be connected in parallel on the first group of coil of single-circuit transformer T and the three-phase normally opened contact of the three-phase ac contactor KM2 between second group of coil respectively, be connected in parallel on the second group of coil of single-circuit transformer T and the three-phase normally opened contact of the three-phase ac contactor KM3 between the 3rd group of coil respectively.U, V, W after the three-phase normally opened contact parallel connection of three-phase ac contactor KM1, KM2 and KM3 constitute output with center line N.Each is controlled the coil of three-phase ac contactor KM1, KM2 and KM3 by automatic control circuit.
Three-phase normally opened contact disconnection as three-phase ac contactor KM4, and the three-phase normally opened contact adhesive of three-phase ac contactor KM1, during the three-phase normally opened contact adhesive of three-phase ac contactor KM2 or KM3 simultaneously, T does not work because of single-circuit transformer, civil power directly exports the output of U, V, W and center line N to through KM1, output be normal voltage.Corresponding working hour of this moment should be that the street lamp point lighted before late 22 o'clock.The up people of this time channel, vehicle are a lot, and the higher illumination of brightness ought to be arranged.
When the three-phase normally opened contact disconnection of three-phase ac contactor KM4, the three-phase normally opened contact of three-phase ac contactor KM1 also disconnect, and during the three-phase normally opened contact adhesive of three-phase ac contactor KM2 or KM3, T does not work because of single-circuit transformer, civil power exports the output of U, V, W and center line N to respectively through first group of coil of single-circuit transformer T, first group of coil and second group of reactor that coil is formed after the step-down.Output be voltage after the reactor step-down.Corresponding working hour of this moment should be late 22 up to late 0 o'clock, and the up people of this time channel, vehicle reduce gradually, and the lower illumination of brightness can be arranged.
Three-phase normally opened contact adhesive as three-phase ac contactor KM4, and the three-phase normally opened contact of three-phase ac contactor KM1 disconnects, during the three-phase normally opened contact adhesive of three-phase ac contactor KM2 or KM3 simultaneously, T enters operating state because of single-circuit transformer, civil power exports the output of U, V, W and center line N to after the step-down of single-circuit transformer T, output be the voltage that reduces.Corresponding working hour of this moment should be lately to rise to daybreak zero the time.The up people of this time channel, vehicle seldom ought to have the minimum illumination of brightness.
As for the control of three-phase ac contactor KM1～KM4, adopt existing street lamp automatic control technology to get final product.
Task of the present utility model comes to this and finishes.
The utility model provides a kind of can provide different voltage in the different periods at night to street lamp automatically according to actual conditions, thus saves energy greatly; And do not have outage, can realize that zero switches; Almost be applicable to all various street lamps, especially can guarantee the electricity saving of road lamp controller of the operate as normal of gaseous discharge lamp in the step-down handoff procedure such as high-pressure sodium lamp, mercury lamp.It can be widely used in the automatic control of various street lamps.
