Description

The light electricity-saving appliance of lengthening the life

Technical field

The utility model belongs to electric lighting voltage-reducing and electricity-saving technical field.

Background technology

Along with developing rapidly of China's power industry, especially the improvement of the increase of grid generation gross power and city illumination supply network quality, perplex the supply power voltage situation on the low side of many electricity consumptions department for a long time and improved effectively, but also brought the higher phenomenon of the supply power voltage that the subregion occurred thereupon.And in power supply supply course of conveying, the loss of the supply line in the transmission process can transmit to guarantee that power consumption equipment reaches rated voltage with higher voltage.Therefore user's reality bears the rated voltage that voltage can be higher than ligthing paraphernalia or equipment.Because electric power system power supply peak period power consumption is bigger, causes terminal temperature difference voltage lower, for guaranteeing peak of power consumption dynamical system energy operate as normal, transformer output voltage design load will be higher than the electrical equipment rated value.When especially having power-equipment in power load, the output voltage of power transformer often is higher than rated value about 10%.

Higher operating voltage will make the power consumption of light source and attached electrical equipment thereof obviously raise, with regard to high-pressure sodium lamp, when operating voltage rises to 1.1 times of rated voltage, its power consumption will increase to 1.3 times of rated value, resemble city street lamp in the second half of the night because network load minimizing line voltage rises on the contrary, will waste a large amount of electric energy this moment.

Higher operating voltage will have a strong impact on the useful life of light source and attached electrical equipment thereof, be example with the ordinary incandescent lamp, and when its operating voltage rising 5%, the life-span will shorten half, and conversely, if operating voltage reduces by 5%, then average life span will prolong one times.

Summary of the invention

The purpose of this utility model provides a kind of light electricity-saving appliance of lengthening the life, the interior lighting system that is used for city street lamp illuminator and market, school, factory and enterprise, the useful life of realizing economize on electricity and prolongation bulb by the method for the high order harmonic component in step-down and the elimination system.

The light of the present invention electricity-saving appliance of lengthening the life is to rely on the tapped step-down reactor of novel single air gap L, capacitor C ₁, C ₂With formation such as piezo-resistance R, solve mainly because of line voltage that the excessive bulb power consumption that causes of high order harmonic component deal in the higher and electrical network increases and the problem of the lost of life.This light electricity-saving appliance of lengthening the life is implemented the voltage-reducing and electricity-saving operation to all kinds of electric light source colony, can reach more than 20% at the electric energy during the brownout operation, and prolong the useful life of light source effectively.Its single-phase light lengthen the life electricity-saving appliance circuit theory diagrams as shown in Figure 1.

In the accompanying drawing 1, L is the tapped step-down reactor of novel single air gap, and it is serially connected in the main line of illuminator, and the pressure drop that utilizes rail current to be produced on reactor reduces the higher operating voltage that electric light source bears.By L, C ₁, C ₂The high order harmonic component filter that is constituted filters the higher harmonic components in the power supply, with power conditioner, reduces the supplementary load loss of light source and attached electrical equipment thereof.Piezo-resistance in the accompanying drawing 1 plays the absorption peak voltage, protection light source and attached electrical equipment effect thereof.

Reactor in the accompanying drawing 1 adopts C type, CD type or O sections cored structure, in order to reduce the reactor running noises and to guarantee that reactor has the good operation characteristic, adopted whole core structure in the design, only leave suitable air gap delta or do not have the air-gap iron core structure in the cutting of one side warp, for the ease of the coiling reactor winding with reduce the reactor copper loss, adopt copper belt to carry fish paper secretly and come coiling, its core structure is shown in accompanying drawing two.

First innovation part of this reactor is to adopt single air-gap iron core structure, thereby has reduced the running noises (its noise is less than 55dB when normally moving) of reactor effectively; Second innovation part is to adopt copper belt to replace traditional two glass flat type copper wires, thereby saved the coiling space effectively, improved the radiating effect of reactor.

The crucial part of the designing technique of this reactor is to calculate single gas length scientifically and rationally, otherwise will influence iron core utilization or influence the iron core temperature rise.We have adopted following approximate formula in design:

$\mathrm{\δ}=\frac{\mathrm{INK}}{1.13B_m}$

In the formula: I is the coil rating electric current

N is a coil turn

B _mBe the iron core maximum magnetic induction

K needs coefficient for design
