Problems solved by technology

When the automatic transfer switch is manually operated, since the motor part of the transmission mechanism has no clutch structure, when the handle is turned, the output shaft of the motor will be driven to rotate together, resulting in a large manual operation force and reducing the operational stability of the transmission mechanism.
The transmission mechanism of some existing automatic transfer switches is also equipped with a clutch structure. In this clutch structure, a solenoid valve is used to drive the push rod to lock, so that there are many parts in the clutch structure and the installation is complicated and the efficiency is low. At the same time, the push rod is in the process of action. There is a problem of jamming, which reduces the reliability of the transmission mechanism
Moreover, the action of the existing solenoid valve is controlled and driven by the controller, so there is a hidden danger of malfunction

Embodiment Construction

[0024] The following is attached Figures 1 to 8 The embodiment of the present invention is given to further illustrate the specific implementation of the transmission mechanism of the automatic transfer switch of the present invention. The transmission mechanism of the automatic transfer switch of the present invention is not limited to the description of the following embodiments.

[0025] The automatic transfer switch of the present invention comprises the transmission mechanism 1 fixedly installed on the base plate 300, the executive switch 3 and the controller 15, such as Figure 8 As shown, execution switches 3 are respectively installed on both sides of the transmission mechanism 1 so that the transmission mechanism 1 can be mechanically coupled with two execution switches 3 nearby. The execution switch 3 includes a push rod 301 that can drive the execution switch 3 to act. The above-mentioned push rod is connected with the rocker arm 12c of the transmission mechanism ...

Abstract

The automatic transfer switch transmission mechanism, the transmission mechanism includes a motor, an output shaft and a reduction box, and the planetary gear set used for the clutch between the motor and the output shaft is arranged in the reduction box, and the planetary gear set includes a planetary ring gear installed in relative rotation and the planet carrier, the planet carrier can be connected with the motor and the output shaft respectively, the planet ring gear is sleeved on the outside of the planet carrier, and the outer wall of the planet ring gear is also provided with a boss 111a. The transmission mechanism also includes a lock arm that can swing relative to the reduction box. The end of the lock arm is placed in the reduction box and is arranged corresponding to the planetary ring gear. The end of the lock arm can be connected to the boss in the automatic state. Interference prevents the rotation of the planetary gear and allows the motor to drive the output shaft to rotate. The invention provides an automatic transfer switch transmission mechanism with stable clutch structure, simple operation process and simple mechanical structure.

Description

technical field [0001] The invention relates to the field of low-voltage electrical appliances, in particular to an automatic transfer switch transmission mechanism. Background technique [0002] At present, the automatic transfer switch is composed of an executive switch, a transmission mechanism and a controller. When the automatic transfer switch is manually operated, since the motor part of the transmission mechanism has no clutch structure, the output shaft of the motor will be driven to rotate when the handle is turned, resulting in a large manual operation force and reducing the operational stability of the transmission mechanism. The transmission mechanism of some existing automatic transfer switches is also equipped with a clutch structure. In this clutch structure, a solenoid valve is used to drive the push rod to lock, so that there are many parts in the clutch structure and the installation is complicated and the efficiency is low. At the same time, the push rod ...
