Embodiment 1

[0019] Example 1, such as figure 1 , figure 2 As shown, the dual power automatic transfer switch includes a housing 1, a geared motor 2, a relay 6, a dual power converter 7, a gear set 10 and a control link 11; the geared motor 2 is fixed on the housing 1, specifically through the geared motor 2 ends of the gear to clamp the shell 1 between the geared motor 2 and the gear, and then complete the fixing of the geared motor 2; the gear set 10 is connected to the control link 11; the control link 11 is connected to the dual power converter 7; The power automatic transfer switch also includes an adjustment rotating shaft 3 and a manual rotating shaft 4 . In the manual state, turn the manual shaft 4, the gear set 10 connected to the lower part of the manual shaft 4 will drive the control connecting rod 11 to move, further control the connecting rod 11 and then control the adjustment mechanism inside the dual power converter 7 to realize the conversion of up and down isolation reg...

Embodiment 2

[0020] Example 2 as figure 1 , figure 2 Said, further on the basis of the above technical solution, the geared motor 2 is fixed on the shell 1 through gears, and a slide rail 9 is arranged on the shell 1 at the connection between the geared motor 2 and the shell 1, so that the geared motor 2. It can move left and right along the slide rail 9 under the action of external force, so as to realize the engagement and separation of the gear at the lower part of the geared motor 2 and the gear set 10. When the geared motor 2 and the gear set 10 are in a separated state, the alignment of the gear set cannot be completed The control of 10, thereby needs to adjust manual rotating shaft 4 to finish, regulates control. When the gear at the lower end of the geared motor 2 is in a combined state with the gear set 10, the automatic control of the geared motor 2 to the dual power converter 7 can be realized. The lower end of the adjusting shaft is provided with a regulating piece 16, and t...

Embodiment 3

[0021]Embodiment 3 Further on the basis of the technical solution of Embodiment 2, a fixed base plate 8 is also provided between the lower end of the geared motor 2 and the lower gear of the geared motor 2, and the fixed base plate 8 is fixedly connected to the bottom end of the geared motor 2, One end of the adjustment spring 15 is fixed on the fixed piece 5, and the other end is fixed on the fixed bottom plate 8. The fixed floor 8 can slide relative to the housing 1 along the slide rail, thereby driving the reduction motor 2 to slide, thereby realizing the connection between the reduction motor 2 and the gear set 10. union and separation. A fixed base is set between the lower part of the geared motor and the shell, so that the spring can be directly fixed on the fixed base, so that there is no need to worry about the work of the motor being affected by fixing the spring on the geared motor. In addition, the design of the fixed base also makes the geared motor slide along the ...

Abstract

The invention, which belongs to the technical field of change-over switches, in particular relates to a novel dual-power automatic change-over switch comprising a housing (1), a gear motor (2), a relay (6), a dual-power converter (7), a gear set (10) and a control connecting link (11). Besides, the dual-power automatic change-over switch further includes an adjusting shaft (3), a manual rotating shaft (4) and a 12-V direct-current power supply; and the gear motor (2) is connected with the 12-V direct-current power supply electrically. Therefore, the manual and automatic adjustment is realized. The 12-V direct-current power supply provides power for the gear motor directly, so that a defect that a 110-V or 220-V voltage needs to be collected from a wiring terminal of a dual-power converter in the prior art is overcome, the voltage is reduced, and the injury on the human body is reduced.

Description

technical field [0001] The invention belongs to the technical field of transfer switches, in particular to a novel dual-power automatic transfer switch. Background technique [0002] The dual-power automatic transfer switch includes the automatic control transmission mechanism and the dual-power converter. The dual-power converter includes dual power inlets and feedback terminals, as well as internal double isolation and power adjustment mechanisms. Promote the power regulation mechanism, and then complete the conversion of the power supply between the upper and lower isolation, so as to realize the dual power switching of the power converter, such as the exchange between the national grid and the power grid. This structure is well established in the prior art. [0003] At present, the automatic control conversion in the prior art is controlled by the motor, and the power supply of the motor adopts the power supply at the input end of the dual power converter, and the use o...
