Description

A kind of fully automatic pressure-stabilizing type charger

The utility model relates to a kind of charging device, more particularly, is a kind of charging circuit, charger in order to accumulator jar is charged that is made of charging transformer and rectification circuit that comprise.

Transformer rectification charger of the prior art because its structure is limit, exists the little problem of voltage adaptation scope.In order to guarantee to charge normal, damage equipment not, have to the Artificial Control driving switch adjust voltage, electric current charges to storage battery.But the fluctuation range of line voltage is between 160V～280V usually.If during charging, line voltage distribution is 180V, operating personnel will be adjusted at 10Ah with driving switch, storage battery is charged, at this moment, in case line voltage then vary to 260V, charging current sharply increases, if do not adjust immediately, will burn out charger in a short period of time.

Manufacturer is also arranged, cause device failure for fear of high pressure, output voltage is fixed as to hang down the charger that the user has bought hand, and volume is very big, very heavy, but charging current is very little, makes storage battery charging wretched insufficiency.

Another problem that exists in the prior art is, because the frame mode of charging transformer adopts tight coiling, just, only isolates with insulating paper between each layer line circle, and therefore, it is unfavorable to dispel the heat, and transformer is in operation under the high temperature for a long time, is easy to burn.

The purpose of this utility model is to avoid above-mentioned the deficiencies in the prior art part, a kind of fully automatic pressure-stabilizing type charger is provided,, makes charger that Gear-shift switch need not be set by corresponding voltage stabilizing circuit is set, automatically adapt to the variation of supply voltage, in the hope of improving service behaviour.

Another purpose of the present utility model is to improve the winding structure of charging transformer coil in the above-mentioned prior art, improves radiating effect, to improve the functional reliability of charging transformer.

The purpose of this utility model is achieved through the following technical solutions.

The utility model comprises the charging circuit that is made of charging transformer B and rectification circuit D5～D8, its architectural feature is: the voltage detecting circuit that is made of voltage-stabiliser tube W1 and triode BG1 is set, establish the collector series relay J2 coil of managing BG1 three, described relay J 2, its normally opened contact j2-1 is serially connected in the electric power loop of the simple whole group of wire turn n1+n2 of rectifier transformer B, its normally-closed contact j2-2 is serially connected in the electric power loop of rectifier transformer B level part wire turn n2.Its feature also is, described charging transformer B between its every layer line circle, is provided with wooden insulating rod perpendicular to wire turn, and described wooden insulating rod evenly distributes in the turn layers periphery.

Compared with the prior art, the utlity model has following advantage:

1, the utility model can adapt to the mains voltage variations on a large scale of 160V～280V automatically because increase is provided with the voltage stabilizing circuit structure, has greatly improved charging effect, make high pressure not burn out device, and low pressure still can guarantee charging current.

2, owing to realize automatic voltage regulation, need not Artificial Control, thereby when alleviating labor intensity of operating staff, the artificial loss of having avoided operate miss to bring.

3, the utility model transformer device structure is simple, and good heat dissipation effect has improved functional reliability significantly.

4, little, the power of the utility model volume is big, charging is fast, and its stable performance, reliable operation, power savings are good.

Fig. 1 is the utility model electrical block diagram.

Fig. 2 is the signal of the utility model loop construction.

Fig. 3 is Fig. 2 cross section structure schematic diagram.

By the following examples, in conjunction with the accompanying drawings, the utility model is done non-limiting description.

Embodiment:

Referring to Fig. 1, charging circuit is made of charging transformer B and rectification circuit D5～D8, in this charging circuit, is arranged in parallel the charging that is made of voltage-stabiliser tube W3 and controllable silicon SCD and detects the loop.Relay J 1 coil tandem detects in the loop at this, its normally-closed contact j1 is arranged in the power supply input circuit, in the present embodiment, owing to adopt controllable silicon SCD, charging is when finishing, the controllable silicon SCD conducting that is triggered, and relay J 1 coil gets, its contact j1 disconnects, and finishes automatic outage, the silicon controlled setting can be avoided " filling phenomenon again ".The setting of R2, R3, C3, W2 and BG2 among the figure can guarantee not produce misoperation when the storage battery folder sparking of no-load running and user's custom.When this situation took place, because electric current charges to capacitor C 3 by R3, therefore, at first action was the triode BG2 conducting that is triggered, subsequently, the positive terminal of W3 then become low-voltage, controllable silicon SCD no longer is triggered.

As shown in Figure 1, voltage detecting circuit is made of voltage-stabiliser tube W1 and triode BG1.At the collector series relay J2 of triode BG1 coil, described relay J 2, its normally opened contact j2-1 is serially connected in the electric power loop of the simple whole group of wire turn n1+n2 of rectifier transformer B, its normally-closed contact j2-2 is serially connected in the electric power loop of the simple part wire turn of rectifier transformer B n2.This testing circuit can in like manner be provided with many groups, under different line voltages, by the combination of actions of relay contact, changes the former utmost point umber of turn of transformer B, thereby finishes pressure regulation.As shown in the figure, in the present embodiment, gang up phenomenon with the charging operating voltage may exist, the secondary winding of transformer B is provided with respectively, to play the effect of isolation for fear of the voltage stabilizing sampling voltage.

Referring to Fig. 2, Fig. 3, in the present embodiment, between every layer line circle 1 of transformer B, wooden insulating rod 2 is set perpendicular to wire turn 1, described wooden insulating rod 2 evenly distributes in the turn layers periphery.Because the setting of insulating rod 2, making has had little space between turn layers and the layer, thereby good heat dissipation effect.
