Abstract
The utility model provides a double-loop control device for three-wire system illumination, utilizing the coordination of a contactor and a diode and operating two contactors to realize the function of all-light-on, part-of-light-on and all-light-off for all the lights, and avoiding electric energy waste caused by turning on all the lights. Setting multiple groups of the double-loop control device for three-wire system illumination according to the actual requirement can realize on and off of multiple groups of lights.
Description
Technical field
The utility model belongs to the three-wire system lighting field, is specifically related to a kind of double loop control device of three-wire system illumination.
Background technology
In the single-phase three wire system illumination, control the on and off of all lamps usually by a switch.But, can reach illumination requirement according to environment different needs opening section lamp sometimes, then cause waste if all open all lamps.
The utility model content
The technical problem that the utility model will solve is: the double loop control device of a kind of three-wire system illumination is provided, can controls lighting by environmental demand is bright entirely, part is bright, go out entirely.
The utility model is to solve the problems of the technologies described above the technical scheme of being taked to be: a kind of double loop control device of three-wire system illumination; It is characterized in that: 2 branch roads of parallel connection between live wire and zero line: the coil of first the route first button SB10, the second button SB11 and the first contactor KM1 is in series, and wherein the normally opened contact of the first contactor KM1 is parallelly connected with the second button SB11; The coil of second route the 3rd button SB20, the 4th button SB21 and the second contactor KM2 is in series, and wherein the normally opened contact of the second contactor KM2 is parallelly connected with the 4th button SB21; Wherein the first button SB10, the 3rd button SB20 are normally closed, and the second button SB11, the 4th button SB21 often open;
The normally opened contact of the normally opened contact of the first contactor KM1 and the second contactor KM2 is connected respectively, and parallel connection inserts live wire again behind the diode, and wherein the normally opened contact diode in series of the normally opened contact diode in series of the first contactor KM2 and the second contactor KM2 is in the opposite direction;
Be connected a diode between lighting and the live wire, the diode and the forward voltage that connect between partial illumination light fixture and the live wire are consistent, and the diode and the reverse voltage that connect between residue lighting and the live wire are consistent.
Press such scheme, described first to fourth button, first and second contactors all are arranged in the distribution box.
The beneficial effect of the utility model is:
1, utilize the coupling of contactor and diode, through control 2 contactors realize all lightings bright entirely, part is bright and the function of going out entirely, avoids the waste of energy when the opening section lamp can reach brightness requirement.
2, many group the utility model devices can be set according to actual needs, to realize the switch of many group lightings.
3, button and contactor are arranged in the distribution box, are convenient to centralized management and maintenance.

Embodiment
Fig. 1 is the circuit diagram of the utility model one embodiment; 2 branch roads of parallel connection between live wire L and zero line N: the coil of first the route first button SB10, the second button SB11 and the first contactor KM1 is in series, and wherein the normally opened contact of the first contactor KM1 is parallelly connected with the second button SB11; The coil of second route the 3rd button SB20, the 4th button SB21 and the second contactor KM2 is in series, and wherein the normally opened contact of the second contactor KM2 is parallelly connected with the 4th button SB21; Wherein the first button SB10, the 3rd button SB20 are normally closed, and the second button SB11, the 4th button SB21 often open.
The normally opened contact of the first contactor KM1 normally-closed contact of the 5th diode D5, the second contactor KM2 the 6th diode D6 that connects that connects, parallel connection inserts live wire more then, and wherein the 5th diode D5 is consistent with forward voltage, and the 6th diode D6 is consistent with reverse voltage.
Be connected a diode between lighting and the live wire, the diode and the forward voltage that connect between partial illumination light fixture and the live wire are consistent, and the diode and the reverse voltage that connect between residue lighting and the live wire are consistent.Light fixture is connected with live wire L, zero line N and ground wire PE on request.In the present embodiment; The first diode D1 and the forward voltage that connect between the first light fixture L1 and the live wire L are consistent; The second diode D2 and the reverse voltage that connect between the second light fixture L2 and the live wire are consistent; The 3rd diode D3 and the forward voltage that connect between the 3rd light fixture L3 and the live wire are consistent, and the 4th diode D4 and the reverse voltage that connect between the 4th light fixture L4 and the live wire are consistent ... And the like.
First to fourth button, first and second contactors all are arranged in the distribution box.
When surrounding environment more secretly needs all illuminations, press the second button SB11 and the 4th button SB21, the first contactor KM1 and second contactor coil get electric, and its normally opened contact is closed, makes the phase line current circuit connect.Forward voltage lights lighting L1 (L3) through diode D5 and D1 (D3), and reverse voltage lights lighting L2 (L4) through diode D6 and D2 (D4).Light fixture is all lighted.
When only needing partial illumination, can (1) press the second button SB11, the first contactor KM1 coil gets electric, and its normally opened contact closure makes forward voltage pass through diode D5 and D1 (D3) lights lighting L1 (L3); (2) press the 4th button SB21, the second contactor KM2 coil gets electric, and its normally opened contact is closed, and reverse voltage lights lighting L2 (L4) through diode D6 and D2 (D4).
