Description
Technical field
The utility model relates to a kind of automatic change-over for low-voltage electrical apparatus, belongs to low-voltage electrical apparatus manufacturing technology field.
Background technology
Automatic change-over is commonly called as " duplicate supply ", is applicable in the electric power system of conventional power supply (electrical network) and stand-by power supply (electrical network or generator), the raw fault because wherein riches all the way and the automatic conversion carried out between power supply.Automatic change-over generally divides with a mechanism controls two circuit breakers, closes a floodgate.At present, normally used automatic change-over, its structure as shown in Figure 1, primarily of support 1, connecting rod 2, 7, pillar 3, 8, sensitive switch 4, cam 5, motor shaft 6 forms, its operation principle: motor shaft 6 driving cam 5 rotates, pin 5A on cam 5 snaps in connecting rod 2, in the elongated slot (being covered by cam 5 in figure) of 7, connecting rod 2 or 7 is rotated around pillar 3 or 8 respectively, by connecting rod 2, the roller of 7 leading sections promotes left side or right side breaker closing or separating brake respectively, two sensitive switches 4 act in the outer rim of cam 5, for switching on or off the electric current of motor in good time.Although the structure of this automatic change-over is simple, install also more for convenience, because motor volume is large, electrical current is large, easily causes sensitive switch 4 contact burning; In addition, sensitive switch 4 regulates inconvenience in addition, if regulate not in place, just there will be jitter phenomenon during electric machine rotation, thus causes the generation of electrical equipment accident.
Summary of the invention
In view of above-mentioned Problems existing, the purpose of this utility model is to provide that a kind of compact conformation, volume are little, the new type auto change over switch of simple installation, dependable performance.
For achieving the above object, the utility model takes following technical scheme:
The new type auto change over switch of one described in the utility model, include: handle, connecting lever, gear, tooth bar, motor, central gear, gear shaft, body, bearing, base and sensitive switch, is characterized in that: motor, guide vane end stop and bearing are fixed on base; Connecting lever, gear, tooth bar and central gear are arranged on body; Handle is connected by gear shaft with central gear, and connecting lever is connected by pin with gear.
As preferably, described tooth bar is two, is arranged in the both sides of central gear, in being arranged parallel to each other.
As preferably, described central gear is imperfect gear, is arranged at the two imperfect gears in place circumferentially, respectively has three teeth, and the between cog angle of the two imperfect gears in place is 43 ° ~ 45 °.
As preferably, described motor adopts micromachine, and this motor volume is little, not only can reduce the volume of automatic change-over, and has small area analysis and energy-conservation advantage.
The utility model after above-mentioned design, compact conformation, volume are little, simple installation, because adopted motor is micromachine, not only efficiently reduce the volume of automatic change-over, and have good energy-saving effect.

Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail:
See accompanying drawing, the new type auto change over switch of one described in the utility model, include: handle 9, connecting lever 10, gear 12, tooth bar 13, motor 17, central gear 18, gear shaft 20, body 14, bearing 15, base 16 and sensitive switch 4, is characterized in that: motor 17, guide vane end stop 21 and bearing 15 are fixed on base 16; Connecting lever 10, gear 12, tooth bar 13 and central gear 18 are arranged on body 14; Handle 9 is connected by gear shaft 20 with central gear 18; Described tooth bar 13 is two, and the both sides being arranged in central gear are arranged in parallel.Described central gear 18 is imperfect gear, and be arranged at the two imperfect gears in place circumferentially, respectively have three teeth, the between cog angle of the two imperfect gears in place is 43 °.Connecting lever 10 is connected by pin 11 with gear 12.Described motor 17 adopts micromachine, and this micromachine volume is little, not only can reduce the volume of automatic change-over, and has small area analysis and energy-conservation advantage.
Working method of the present utility model is achieved like this:
During work, motor 17 by gear 19, gear shaft 20 by transmission of power to handle 9 and central gear 18, when handle 9 rotates, the state of circuit breaker (conventional circuit breaker closes, back-up breaker closes, two points) can be indicated.Now, can operating mechanism by handle 9, control the splitting or integrating lock of both sides circuit breaker.When central gear 18 rotates, because central gear 18 is imperfect gear, and the between cog angle of the two imperfect gears in place is 43 ° ~ 45 °, therefore left side or tooth bar 13 slippage of side, right side can only be driven, thus drive left side or right side one side gear 12 to rotate, transmitted by pin 11, drive left side or side, right side connecting lever 10 to rotate, connecting lever 10 entangles the handle of circuit breaker from the side, thus can make breaker closing or the separating brake of left side or side, right side.Be respectively equipped with sensitive switch 4 in the side of left and right connecting lever 10, switch on or off in order to control current of electric.Guide vane end stop 21 mainly plays interlocking effect to both sides tooth bar 13, only allows side tooth bar to be in upper end position, prevents both sides circuit breaker from closing a floodgate simultaneously.
