Abstract
The utility model discloses an intelligent power saver for lighting system, which comprises a voltage-reducing current-limiting coil disposed between a commercial power input and a load, a CPU connected to the voltage-reducing current-limiting coil, and current sampling systems and voltage sampling systems disposed between an input of the voltage-reducing current-limiting coil and the CPU and an output of the voltage-reducing current-limiting coil and the CPU. The CPU controls the voltage-reducing current-limiting coil, base on the collected current and voltage values, so as to output current and voltage of the predetermined values for the load. Since voltage-reducing current-limiting coil is disposed between the commercial power input and the load and connected to the CPU, the output voltage is automatically regulated according to the value of input voltage, so that excessive electric energy is reduced to supply stable current to the electric appliance and the maintenance of electric appliance is reduced. Therefore, the utility model can reduce the loss of lighting instrument, reduce the cost of maintenance, and prolong the service life of lighting instrument.
Description
Technical field

Background technology
Present China power tense, the light load will be along with peak times of power consumption or low peak period and is changed, generally in the part light fixtures of peak times of power consumption is operated in setting voltage even lower voltage range, but then be operated under the high voltage at electricity consumption low peak period light fixture, this high-tension operating state makes aging serious, the lost of life of light fixture facility, and wastes unnecessary power consumption.
The utility model content
At above-mentioned situation, the purpose of this utility model be to provide a kind of can make output voltage with the height difference of input voltage the intelligent lighting system power saver of timely adjustment.
For achieving the above object, technical solution of the present utility model is:
A kind of intelligent lighting system power saver, comprise the step-down current-limiting inductor of being located between mains current input and the load, this step-down current-limiting inductor connects central processing unit, and be equipped with current sampling system and voltage sampling system between the input of step-down current-limiting inductor and the central processing unit and between the output of step-down current-limiting inductor and the central processing unit, central processing unit makes the output of step-down current-limiting inductor and the setting electric current of load, the electric current that magnitude of voltage is consistent according to the electric current that collects, magnitude of voltage control step-down current-limiting inductor.
Further, described step-down current-limiting inductor is formed series circuit with two relays of being located at step-down current-limiting inductor upstream and downstream respectively, and this series circuit is in parallel with another relay, and described three relays all are connected with central processing unit.
Further, described step-down current-limiting inductor is in series by three transformers.
Because the utility model is provided with the step-down current-limiting inductor between mains current input and load, the step-down current-limiting inductor is connected with central processing unit, can be according to the height of input voltage, automatically regulate output end voltage, reduce unnecessary electric energy, make the current stabilization of input electrical appliance, the maintenance capacity of electrical appliance reduces, the loss of light fixture and manual maintenance expense are all saved greatly, have prolonged the useful life of light fixture; In addition, described step-down current-limiting inductor is formed series circuit with two relays of being located at step-down current-limiting inductor upstream and downstream respectively, this series circuit is in parallel with another relay, described three relays all are connected with central processing unit, therefore when mains current, voltage are lower than the electrical appliance set point, when this electricity-saving appliance transfers civil power to by electricity-saving state, export not power down, light does not glimmer; Design has manual, automatic control mode in the secondary line, and is also remote controlled; That this electricity-saving appliance can be used for is single-phase, the light fixture class load of three-phase, is applied to occasions such as square, market, supermarket, hotels, office building, highway lamp.

Embodiment:
As shown in Figure 1, the utility model intelligent lighting system power saver comprises relay K M1, KM2, KM3, two current sampling systems 1,2, two voltage sampling systems 3,4, step-down current-limiting inductor 5 and central processing unit 6, mains current in the electrical network is through current sampling system 1, voltage sampling system 3 back input central processing units 6, the control end of central processing unit 6 connects step-down current-limiting inductor 5 and relay K M1, KM2, KM3, relay K M2, the series circuit that step-down current-limiting inductor 5 and relay K M3 form is in parallel with relay K M1, current sampling system 1, electric current that voltage sampling system 2 gathers and magnitude of voltage input central controller 6, electric current when civil power, magnitude of voltage is when the set point of electrical appliance and set point are following, central processing unit 6 control relay KM1 adhesives, disconnect KM2 then, KM3, make mains current directly enter electrical appliance, electric current when civil power, magnitude of voltage is during greater than the set point of electrical appliance, relay K M1 disconnects, KM2, the KM3 adhesive, the electric current that mains current is exported behind step-down current-limiting inductor 5 is through current sampling system 2, back input central processing unit 6 is gathered by voltage sampling system 4, central processing unit 6 is controlled step-down current-limiting inductors 5, makes the setting electric current of 5 outputs of step-down current-limiting inductor and electrical appliance, the electric current that magnitude of voltage is consistent.
Main circuit connection layout of the present utility model as shown in Figure 2, described step-down current-limiting inductor 5 is in series by T1, T2, three transformers of T3,0V, 5V, 10V, 15V, 20V, 25V, seven shelves of 30V, 35V can be reasonably combinedly finished in use in major loop, the pressure regulation of 0-35V reduces power, play energy-conservation effect, and the size of adjustment power, output is rationally regulated in getting in touch by system between load and the power supply.
As shown in Figure 3, the connection of J1: 14 connecting to neutral line N, 13 connect the auxiliary normally opened contact 14 of A.C. contactor KM1, and auxiliary normally closed 4 of J1 meets loop A 1 end of economize on electricity A.C. contactor KM2, KM3, the loop A 2 connecting to neutral line N of KM2, KM3.The auxiliary normally closed other end 12 of J1 connects on the other end 12 phase-connecting wires of auxiliary contact 4, J2 of J2 relay.When relay J 2 adhesive actions or key switch KEY closure, the KM1 coil gets electric, auxiliary contact 13,14 closures, and the coil of J1 gets electric, and the normally closed interlock 12-4 of J1 disconnects, the KM2 of the electricity-saving state that breaks, the wire loop of KM3, KM2, KM3 discharge.Key switch KEY or relay J 2 actions, coil blackout → KM2, the KM3 of KM1 bypass contactor adhesive → relay J 1 adhesive → KM2, KM3 discharges, and the economize on electricity part throws away.
Because the adhesive of bypass contact-relay KM1 elder generation, and then disconnect the electricity of KM2, KM3 in the major loop, economize on electricity can not occur changes power down in city's electric process.
