Abstract
The utility model relates to the technical field of power supply, in particular to a double power automatic change-over switch, which comprises a bottom board, wherein a face shield is arranged on the bottom board, a motor is arranged on the center of the bottom board, and the motor heads of the motor are arranged on push pendulums on the two sides of the bottom board, the push pendulums are connected with a circuit-breaker, the motor shaft of the motor is connected with a microswitch, and is connected with a handle arranged above the face shield. Compared with the prior art, the double power automatic change-over switch of the utility model can conveniently realize the conversion of a commonly used power supply and a standby power supply, and the functions of overload and short-circuit protection, and has small volume, economy and suitability.
Description
Technical field
The utility model relates to the power supply technique field, and a kind of double power supply automatic transfer switch specifically is provided.
Background technology
Twin-power switch has two kinds in the market, a kind ofly is made up of motor, mechanical interlocking, circuit breaker, controller, sensitive switch, and the driven by motor driver chuck promotes the divide-shut brake action, and it is compact that the more mechanical engagement of all accessories is owed, and volume is big.Another kind partly is made up of mechanism, coil, bakelite dynamic/static contact, and mechanism's partial design is loaded down with trivial details, and the conversion between the standing power supply is subjected to the factor of coil electromagnetism adhesive restriction bigger, and the dynamic/static contact contact pressure size of bakelite side directly influences ducting capacity.The not outer dispensing of manual operation handle is unfavorable for manual random operation.
Summary of the invention
The utility model is at above deficiency, and a kind of double power supply automatic transfer switch is provided, and realizes the conversion between power supply commonly used and the stand-by power supply easily, can realize functions such as overload, short-circuit protection again, and volume small economy is suitable for.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of double power supply automatic transfer switch, comprise base plate, described base plate is provided with face shield, it is characterized in that, described base plate central authorities are provided with motor, and the motor head of described motor is connected in the pendulum that pushes away of base plate both sides by connector, and the described pendulum that pushes away connects circuit breaker, the motor shaft of described motor connects sensitive switch, and is connected in the handle above the face shield.
Described motor top is provided with controller.
Described motor shaft top is provided with axle sleeve, and described axle sleeve side is provided with the wedge shape circular shaft.
A kind of double power supply automatic transfer switch of the present utility model has following characteristics:
1, side commonly used adopts miniature circuit breaker to be connected power supply and load with prepped side, makes dual-power transfer switch have functions such as overload, short-circuit protection.
2, in mechanical interlock mechanism, motor shaft sleeve and motor shaft pin with the wedge shape circular shaft, do not have displacement synchronously and skid in the motor rotary course.
3, the ornaments that push away that promote the divide-shut brake of circuit breaker are counted into grooved and are cooperated compactness with circuit breaker, two ends are lived with the mounting fixing parts embedding respectively, and be tightened to one with screw and circuit breaker, the handle that motor directly promotes circuit breaker when rotated makes its action realize divide-shut brake, and sequential is stirred the sensitive switch contact chip in accordance with regulations, reaches the conversion between the stand-by power supply commonly used.
4, power supply indication and "on" position indication are installed with the compact one of LED.Design the fail safe that outer cover has guaranteed electricity consumption, the aesthetics of the product of Zeng Jiaing again in the circuit breaker outside.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a kind of external structure schematic diagram of double power supply automatic transfer switch;
Fig. 2 is a kind of internal structure schematic diagram of double power supply automatic transfer switch;
Fig. 3 is a kind of internal structure schematic diagram of double power supply automatic transfer switch;
Fig. 4 is a kind of electric machine structure connection diagram of double power supply automatic transfer switch.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments, but not as to qualification of the present utility model.
Provide a most preferred embodiment below:
A kind of double power supply automatic transfer switch, comprise base plate 1, described base plate 1 is provided with face shield 2, described base plate 1 central authorities are provided with motor 3, the motor head 4 of described motor 3 is connected in pushing away of base plate 1 both sides by connector 5 and puts 6, the described pendulum 6 that pushes away connects circuit breaker 7, and the motor shaft 8 of described motor 3 connects sensitive switch 9, and is connected in the handle 10 above the face shield 2.
Described motor 3 tops are provided with controller 11.
Described motor shaft 8 tops are provided with axle sleeve 12, and described axle sleeve 12 sides are provided with wedge shape circular shaft 13.
Above-described embodiment, the utility model embodiment a kind of more preferably just, the common variation that those skilled in the art carries out in the technical solutions of the utility model scope and replacing all should be included in the protection range of the present utility model.
Claims (3)
