Problems solved by technology
[0004] 1. Two coils will be used in the selection device, which will inevitably increase the production cost of the product;
[0005] 2. The structure of the common and standby power selection device becomes complicated, which leads to more complicated and cumbersome assembly;
[0006] 3. The complex structure is not easy to repair and maintain;
[0007] 4. Due to the large number of parts, the friction force generated during the movement must be relatively large, which greatly affects the action of the automatic transfer switch

Embodiment Construction
[0021] Below the present invention will be further described in conjunction with the embodiment in the accompanying drawing:
[0022] Such as Figure 1~2 As shown, the present invention mainly includes a control link 1, a selection link 2, a driven link 3, a basic link 4, a common power closing link 5 and a backup power closing link 6.
[0023] The middle part of the basic connecting rod 4 is connected to the lower end of the control connecting rod 1 through the first rotating shaft 12 , and a bushing 13 is arranged between the first rotating shaft 12 and the controlling connecting rod 1 .
[0024] The right part of the basic connecting rod 4 is connected to the lower end of the driven connecting rod 3 by the second pin shaft 10, and the upper end of the driven connecting rod 3 is connected to the right end of the selected connecting rod 2 by the first pin shaft 8. The second cotter pin 10 is provided with a second cotter pin 11, and the second cotter pin 11 is used to limit ...

The invention relates to an automatic transfer switching device, in particular to a selection device for normally-used and emergency power supplies of the automatic transfer switching device, belonging to the technical field of a power supply device. The selection device comprises a control connection rod, a selection connection rod, a driven connection rod, a basic connection rod, a normally-used power supply switch-on connection rod and an emergency power supply switch-on connection rod, wherein the middle part of the basic connection rod is connected with the lower end of the control connection rod by a first rotation shaft, the right part of the basic connection rod is connected with the lower end of the driven connection rod by a second pin shaft, the upper end of the driven connection rod is connected with the right end of the selection connection rod by a first pin, and the middle part of the selection connection rod is sequentially connected with the middle part of the control connection rod and the right ends of the normally-used power supply switch-on connection rod and the emergency power supply switch-on connection rod by a central shaft. Since only a main coil is used for carrying out switch-on and switch-off motions on an automatic transfer switch, an extra latch tripping device is not needed to be arranged, thus, the production cost of a product is greatly reduced, and meanwhile, the selection device becomes more safe and reliable.
Description
technical field [0001] The invention relates to an automatic switch electric appliance, in particular to a selection device for common and standby power sources of the automatic switch electric appliance, which belongs to the technical field of power supply equipment. Background technique [0002] The normal and standby power selection device is an important component mechanism in automatic transfer switching appliances. The existing common and standby power selection devices are usually composed of two coils, that is, one coil that controls the closing and opening of the normal power supply, and controls the closing and opening of the standby power supply. When the coil of the common power supply is energized instantly, the coil pulls in to drive the linkage mechanism to close to the normal power supply; when the backup power coil is energized for a moment, the coil pulls in The connecting rod mechanism closes to the standby power supply, so as to achieve the purpose of sel...
