Problems solved by technology

[0007] The purpose of the present invention is to overcome that when the circuit breaker and the opening and closing device are used together in the prior art, the coaxial and concentric transmission requirements of multiple axes cannot be met, and the deflection and shaking of the multiple axes are easily caused, so that the jamming of the handle affects the transmission effect and increases the speed. To solve the problem of large motor bearing load, thus providing an automatic reclosing device that realizes coaxial and concentric transmission of the linkage shaft, stable and reliable cooperative transmission, and prolongs the service life of the motor

Embodiment 1

[0064] Attached below Figure 1-12 A kind of automatic reclosing device provided in this embodiment is described in detail:

[0065] This embodiment provides an automatic reclosing device, including a housing structure, at least one circuit breaker component and a reclosing control unit; the circuit breaker component includes a static contact and a moving contact arranged in the housing structure, and an operating mechanism that drives the static contact and the moving contact to contact or disconnect, the operating mechanism includes a circuit breaker handle 3 rotatably arranged on the housing structure; the reclosing control unit is located at In the housing structure, the operating mechanism is driven to open or close, and includes a driving device, a transmission mechanism driven by the driving device, and a control module for controlling the operation of the driving device;

[0066] It also includes: a coaxial linkage mechanism, connected between the transmission mechani...

Embodiment 2

[0086] This embodiment is a modification based on Embodiment 1. The difference between this embodiment and Embodiment 1 is that, as Figure 5 and Figure 12 As shown, another setting method of the rotation positioning structure is: the rotation positioning structure further includes: two shafts that are respectively formed in the first rotating shaft 10 and the second rotating shaft 20 and are axially opposite The hole, and the turntable 51 fixedly arranged on both ends of the linkage shaft 5 and connected to the shaft hole in rotation, provides positioning connection for the linkage shaft by means of the rotation cooperation formed by the turntable and the shaft hole.

[0087] Further preferred, such as Figure 12 As shown, the turntable 51 includes a first cylinder and a second cylinder coaxially arranged, the diameter of the first cylinder is greater than the diameter of the second cylinder; the first cylinder is formed with The connection hole matched with the two ends o...

Abstract

The invention discloses an automatic reclosing device. The device includes a housing structure, at least one circuit breaker component and a reclosing control unit, and further includes a coaxial linkage mechanism which is connected between a transmission mechanism and a circuit breaker handle and transmits movement. The coaxial linkage mechanism includes a linkage shaft and a drive component installed between two ends of the linkage shaft in a linkage manner. The two ends of the linkage shaft extending from the circuit breaker handle are respectively connected on the housing structure in a rotatable manner. In the technical scheme, a connection mode of positioning rotation of the two ends of the linkage shaft is adopted, the two ends of the linkage shaft are enabled to not deviate from a central axis thereof and be tilted and swayed, real coaxial concentric transmission of the linkage shaft and the circuit breaker handle and the drive component is realized, the transmission effect is better, and the use performance of a product is improved.

Description

technical field [0001] The invention relates to the technical field of low-voltage electrical appliances, in particular to an automatic reclosing device. Background technique [0002] With the promotion of the smart grid, the use of electric energy metering devices such as IC card prepaid meters is becoming more and more popular. The circuit breaker that needs to be manually operated can no longer meet the requirements of the smart grid. Therefore, it is necessary to match the breaker specially used for the prepaid meter The circuit breaker product can realize automatic reclosing operation, transmit a control signal, and then realize remote control, so that the circuit breaker can be automatically closed or opened, without the need for staff to manually open and close, effectively saving manpower and material resources . [0003] According to the intelligent requirements of my country's power supply network, the small circuit breaker of the terminal actuator of the power gr...
