Embodiment Construction

[0016] Such as figure 1 , figure 2 , Figure 5 As shown, the present invention is an operating module of a small air switch, including a circuit breaker handle 1 , a tripping member 2 , a first gear 3 , a second gear 4 , a third gear 5 , and a first rotating shaft 6 .

[0017] The first gear 3 is a sector-shaped partial gear, and the angle α of its sector-shaped partial teeth is 90 degrees (that is, the closing angle). The first gear 3 and the inner end of the breaker handle 1 are both socketed on the first rotating shaft 6. Set for coaxial.

[0018] combine Figure 4 As shown, one end of the release member 2 has a shaft hole 21 , the other end has a collar 22 , and the boss 23 extends outward from one side of its middle. One end of the tripping part 2 has a shaft hole 21 and the tripping part 2 shaft hole 21 is coaxial with the circuit breaker jumper 7, and the other end of the tripping part 2 has a collar 22 and the tripping part 2 sets The ring 22 is concentric with t...

Abstract

The invention discloses an operation module for a small-sized air switch. The operation module comprises a circuit breaker handle, a releasing part, a first gear, a second gear and a third gear, wherein the first gear is a fan-shaped partial gear, and the angle of the fan-shaped partial teeth is 90 degrees; the inner ends of the first gear and the circuit breaker handle are both arranged in a first rotating shaft in a sleeving manner; the second gear is a coaxial gear, and consists of a rack wheel and a pinion; the pinion is a fan-shaped partial gear and provided with a lug boss; the pinion is meshed with the first gear; and the lug boss on the pinion can support a lug boss on the releasing part in a jacking manner in the rotating process. According to the operation module, a set of motor and gear driving mechanism is adopted, so that the operation module can realize a closing operation and an opening operation as well; the motor only needs to rotate in a single direction; the opening operation is implemented by adopting a drive gear to realize release in the interior of the switch, and dependence on the handle is prevented; the circuit breaker is not damaged even if a user has a misoperation on the handle to result in closing after the opening operation; and the operation module is simple and reliable in structure, reliable in action, small in size, relatively low in cost and capable of saving space.

Description

technical field [0001] The invention relates to a switchgear, in particular to an operating module of a small air switch. Background technique [0002] The drive module (also known as the electric operation module) of the existing small air switch needs to be able to drive the switch to close and to drive the switch to open. At present, there is a solution: use a motor to drive a small circuit breaker The handle is used to close the brake, and then the motor is turned in the opposite direction to open the brake. The action sequence of the motor and gear mechanism is as follows: when the motor and its gear mechanism drive the switch to close in place, since the next opening operation may be manual operation, in order to make the driving mechanism no longer withstand the handle, the motor needs to reverse immediately. Rotate; when the opening is completed, the motor also needs to rotate in the opposite direction again, so that the driving mechanism no longer withstands the ha...
