Example Embodiment

[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 end gears to clamp the housing 1 between the reduction motor 2 and the gears, thereby completing the fixation of the reduction 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 automatic power transfer switch also includes an adjusting shaft 3 and a manual shaft 4. In the manual state, rotate the manual shaft 4, the gear set 10 connected to the lower part of the manual shaft 4 will drive the control link 11 to move, and further control the link 11 and then control the internal adjustment mechanism of the dual power converter 7 to realize the upper and lower isolation conversion Adjust to complete the conv...

Example Embodiment

[0020] Example 2 such as figure 1 , figure 2 Said, further on the basis of the above technical solution, the geared motor 2 is fixed on the housing 1 by gears, and a slide rail 9 is provided on the housing 1 where the geared motor 2 and the housing 1 are connected, 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 lower gear of the reduction motor 2 and the gear set 10. When the reduction motor 2 and the gear set 10 are in a separated state, the gear set cannot be completed. The control of 10 needs to be completed by adjusting the manual shaft 4 to adjust the control. When the gear at the lower end of the reduction motor 2 is in a combined state with the gear set 10, the automatic control of the reduction motor 2 to the dual power converter 7 can be realized. An adjusting piece 16 is provided at the lower end of the adjusting shaft. The dual power automatic tra...

Example Embodiment

[0021] Embodiment 3 is further based on the technical solution of embodiment 2, a fixed bottom plate 8 is also provided between the lower end of the reduction motor 2 and the lower gear of the reduction motor 2, and the fixed bottom plate 8 is fixedly connected to the bottom end of the reduction motor 2. One end of the adjusting spring 15 is fixed on the fixed sheet 5, and the other end is fixed on the fixed bottom plate 8. The fixed floor 8 can slide along the slide rail with respect to the housing 1, thereby driving the reduction motor 2 to slide, thereby realizing the reduction motor 2 and the gear set 10 Combination and separation between. A fixed base is set between the lower part of the geared motor and the housing, so that the spring can be directly fixed on the fixed base, so there is no need to worry about fixing the spring on the geared motor and affect the motor work. In addition, the design of the fixed base also makes the geared motor slide along. The rail movement...

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...
