Description

Light control electricity-saving appliance

Technical field

The utility model relates to the electric lighting field, is the matched light control of a kind of illuminator electricity-saving appliance.

Background technology

As everyone knows, in existing electric line, the voltage of most substations output generally will be higher than 220 volts of said at ordinary times nominal voltages, this be owing to transformer station at first in order to adapt to when the peak of power consumption, it is too low that the voltage of transmission line end is unlikely to.Another reason is that the voltage that transmission line suitably improves in transformer station is to make the cost of transmission line in order to save frame.Because the high more caused line loss of transmission line voltage in same length is low more, so these reasons have caused the too high sometimes cause of voltage; In this case, many ligthing paraphernalias are to be operated in the state of superpressure, to be ligthing paraphernalia be converted into heat energy to that a part of electric energy of exceeding specified normal working voltage by free consumption to the consequence of bringing like this, the wasting phenomenon that has caused the energy, but also cause ligthing paraphernalia under the condition of superpressure, to work, impel the shortening in its useful life.

Existing illuminator electricity-saving controller has plenty of at single load, though transforming at whole lighting loop of having, what adopt is the controllable silicon technology.Because of the product of controllable silicon technology can produce the harmonic pollution power quality when the operation, influenced the electric loading of using on the circuit.

Summary of the invention

The utility model will provide a kind of light control electricity-saving appliance to this area at above-mentioned technical problem, under the state that solves overtension, input in the ligthing paraphernalia by this electricity-saving appliance earlier again, and ligthing paraphernalia is worked under the voltage conditions of the best.Now in conjunction with the following drawings, its feature is described as follows:

A kind of light control electricity-saving appliance, the control circuit of this electricity-saving appliance comprises: electrical network input unit, power subsystem, major loop control unit, input comparing unit, signal output unit, pressure unit and lead-out terminal are formed; The input that it is characterized in that power subsystem is to be connected with the electrical network input unit by power line, and its output is connected with major loop control unit input with the input of input comparing unit; The output of major loop control unit is connected with the pressure unit input; The input of input comparing unit is connected with the output of power output terminal, electrical network input unit and the output of lead-out terminal; Its output is connected with the signal output unit input; The signal output unit output is connected with major loop control unit input; The output of pressure unit is connected with lead-out terminal.

Mentality of designing of the present utility model is the voltage in the electrical network is carried out real-time tracking, actual conditions according to electrical network are controlled, its core has been to adopt the electromagnetic coupled superimposing technique of original creation, end of the same name and different name end at transformer are provided with the electromagnetic coupled laminating module, utilize the relation of transformer end of the same name itself and different name end to be added on to develop the designed a kind of electromagnet coupling superimposing technique that goes out exactly.

The utility model is wide to the applicability of light fixture, and fitting operation is convenient, dependable performance.It does not adopt the controllable silicon technology, does not produce the harmonic pollution power quality, does not influence the electric loading of using on the circuit, makes corresponding output according to the fluctuation variation of line voltage and changes, and need not the personal monitoring, realizes control automatically.
