Description

A kind of tubule footpath senior executive presses fluorescent-lamp-use leakage field pressure swing type Inductive ballast

Technical field

Invention of the present utility model relates to a kind of Ballasts Used in Fluorescent Light, is that a kind of tubule footpath senior executive presses fluorescent-lamp-use leakage field pressure swing type Inductive ballast specifically.

Background technology

At present, common Inductive ballast can be used as the fluorescent lamp that opens the low pipe pressure of bright big caliber, and press opening of fluorescent lamp bright for tubule footpath senior executive, particularly caliber 16mm (T5) and below and pipe is pressed in the fluorescent lamp more than the 160V, also on the market and do not find to have corresponding Inductive ballast, standard is not temporarily made to the Inductive ballast of such fluorescent lamp by China yet, but can only use electric ballast for opening of such fluorescent lamp is bright.Yet, this common on the market electric ballast, of a great variety, quality between all kinds of is uneven, particularly bum electric ballast, and it is poor reliability not only, life-span is short, and the also setting of overgauge 1.7 of crest factor, seriously shortens the useful life of fluorescent tube; Simultaneously, the current harmonic content that such electric ballast caused often exceeds the permitted maximum range of H grade standard, and it is to the pollution of power supply, and the consequence that causes is serious.

Summary of the invention

Goal of the invention of the present utility model is to overcome the deficiencies in the prior art, provides a kind of reliability height, performance good, and prolonging lamp tube useful life, the tubule footpath senior executive who is easy to popularize press fluorescent-lamp-use leakage field pressure swing type Inductive ballast.

Goal of the invention of the present utility model is achieved in that a kind of tubule footpath senior executive presses fluorescent-lamp-use leakage field pressure swing type Inductive ballast, it is characterized in that: it comprises skeleton, skeleton is provided with elementary winding wire bag and secondary winding line bag, be provided with iron core inside and outside the two line bags, the top of elementary winding, end are power input interface, its end links to each other with the top of secondary winding, and the end of secondary winding and the top of elementary winding are output interface.

Described iron core is matched with " F " matrix that is in these T-shape sheet both sides by notched T-shape sheet and forms.

Described iron core is matched with " L " matrix that is in T-shape sheet both sides by the T-shape sheet and forms.

Described iron core is joined by " E " matrix counterpart and forms.

The two ends of described elementary winding are parallel with building-out capacitor.

The output of described secondary winding is provided with building-out capacitor.

The beneficial effects of the utility model are: this ballast has used the principle design of Inductive ballast and transformer to make.When connecting external power, ballast produces a high voltage and is used to open bright fluorescent tube, this high voltage is just reduced to fluorescent tube end pressure value subsequently, secondary winding on it just plays metering function, good product quality, the dependability height has good stability to the work of fluorescent tube, effectively the useful life of prolonging lamp tube.And this leakage field pressure swing type Inductive ballast can design makes the optimum value that electric current crest factor and current harmonic content all reach standard-required, helps popularizing of product.

Embodiment

The utility model is described in further detail below in conjunction with accompanying drawing.

Extremely shown in Figure 7 according to Fig. 1, tubule of the present utility model footpath senior executive presses fluorescent-lamp-use leakage field pressure swing type Inductive ballast, it comprises skeleton 1 and elementary winding 2 line bags and secondary winding 3 line bags on the skeleton 1, be provided with the iron core 4 that matches with it inside and outside the two line bags, and according to different magnetic effect demands, the version of iron core 4 can be varied, and as shown in Figure 3, iron core 4 is matched with " F " matrix 42 that is in these " T " matrix 41 both sides by notched " T " matrix 41 and forms; As shown in Figure 4, iron core 4 by T-shape sheet 43 and be in " T " matrix 43 both sides " L " matrix 44 matches and forms; And for example shown in Figure 5, iron core 4 by " E " matrix 45 counterparts join and form.After forming the line bags, skeleton 1 and the elementary winding 2 on the skeleton 1 and secondary winding 3 closely be sleeved in the iron core 4, as shown in Figure 1, and, the terminal X of the elementary winding 2 of the utility model links to each other with the top of secondary winding 3 and is connected into common lead-out wire, the ends A of elementary winding 2, X are connected with extraneous power supply, constitute the circuit structure of this ballast with this, as shown in Figure 2.Difference encapsulation requirement according to product, this ballast can be loaded in the fastening shell of open type, on shell, set corresponding binding post, perhaps whole ballast is loaded in the housing of sealing after fastening, at housing embedding packing material, the then available corresponding lead-in wire of the terminals of winding is drawn outside the housing.In the actual design manufacture process, the line footpath of size, material and winding that can be by changing iron core 4 is to reach the electrical loss that reduces ballast to greatest extent.And for further improving the power factor of ballast working line, can realize by following two kinds of approach: the two ends of the elementary winding 2 of the first are parallel with building-out capacitor 5, as shown in Figure 6; It two is that output at secondary winding 3 is provided with building-out capacitor 5, as shown in Figure 7.

When the described ballast of the present utility model connects the electricity zero load, AC power makes and produces a no-load current between A, the X of elementary winding 2, and produce no-load loss immediately, simultaneously, the A of ballast, B end produces an output voltage higher than supply voltage because of the self coupling induction of leakage transformer, and this voltage satisfies the starting voltage needs that the senior executive presses fluorescent lamp.When the operator pressed the K switch on the tube circuit or connects special-purpose starter S, the filament of fluorescent tube just had electric current and flows through, and prepares but this electric current preheating filament makes its emitting electrons be that opening of fluorescent tube is bright.When operator moment cut-off switch K or starter S auto-cutout, will produce a very high back electromotive force between the A of ballast, the B, this back electromotive force puts on lamp tube ends and makes its discharge conducting, thereby opens bright fluorescent tube.Subsequently, the high voltage between A, the B opens the end pressure value that will reduce to fluorescent tube after bright at fluorescent tube, at this moment, 3 metering functions of the secondary winding of ballast, restriction is to the operating current of fluorescent tube output.In view of the above, it is good that the described ballast of the present utility model has quality, and the advantage that dependability is high also effective useful life of prolonging lamp tube, helps popularizing of product.
