Problems solved by technology

[0005] Therefore, the technical problem to be solved by the present invention is to overcome the self-rotation phenomenon of the ratchet wheel in the prior art when it is installed and is far away from the ratchet pawl, so that the ratchet wheel rotates with a section of idle travel, resulting in prolonged closing time, and the ratchet wheel and ratchet. The pawls are prone to jamming due to slight misalignment, which affects the normal operation of the product. Therefore, a clutch wheel can be positioned and installed, and the installation position of the clutch wheel can be calibrated to avoid the jamming phenomenon and shorten the closing time. The reclosing device to ensure the normal operation of the circuit breaker

Embodiment 1

[0039] Below in conjunction with accompanying drawing this embodiment is described in detail:

[0040] This embodiment provides as Figure 1-8 The shown reclosing device of a circuit breaker includes a drive structure 1 and a transmission mechanism installed in the circuit breaker housing 6, and the drive structure 1 drives the circuit breaker handle to perform opening and closing actions through the transmission mechanism. The transmission mechanism includes a gear set 2 that is connected to the driving structure in cooperation with the drive structure. One or two gears of the gear set 2 are provided with a clutch structure 3, and the clutch structure 3 is used to make the gears in the gear set To form a transmission fit in a single direction, that is, to form a linkage fit or a release linkage relationship between the gear set 2 and the drive structure 1 through the clutch structure 3, so as to cut off or transmit the driving force from the drive structure: The clutch struc...

Abstract

The invention discloses a reclosing device of a circuit breaker. The device comprises a driving structure, a gear set and a clutch structure arranged between a driving gear and the driving structure,and the clutch structure comprises a mounting groove arranged in the gear set, a clutch wheel, a limiting piece and an elastic piece, wherein the clutch wheel and the limiting piece are arranged in the mounting groove, and the elastic piece is arranged on a top surface of the clutch wheel in an abutting mode; a one-way positioning structure is arranged between the mounting groove and the clutch wheel so that a pre-positioning effect on a ratchet wheel in the mounting groove is achieved; a triggering distance between the clutch wheel and a pawl can be greatly shortened; and when a power structure drives the gear set to carry out one-way closing rotation through the clutch structure, a long idle stroke between the clutch wheel and the pawl can be avoided, waiting time is greatly reduced, closing time of the circuit breaker is shortened, closing time is ensured to be within a reclosing prescribed range, and use performance of products is improved.

Description

technical field [0001] The invention relates to the technical field of low-voltage electrical appliances, in particular to a reclosing device of a circuit breaker. Background technique [0002] With the promotion of the smart grid, it is required that the circuit breaker products of the terminal actuators of the power grid should have automatic tripping and closing functions when executing the upper-end signal. Among them, the molded case circuit breaker is often used as a terminal switch or a branch switch in the low-voltage power distribution system. , to protect the power line and mechanical equipment in real time. For this reason, by installing an electric reclosing mechanism on the molded case circuit breaker, the automatic opening and closing function of the circuit breaker is realized, and the staff is no longer required to manually open and close. Brake operation effectively saves manpower and material resources, and plays a real-time protection role for power lines ...
