Problems solved by technology

[0003] The current circuit breaker gear, due to excessive load or too many operations, the one-way bearing often fails, resulting in overall reversal and manual energy storage, and it is difficult to disassemble and assemble after this problem occurs, which not only wastes raw materials but also greatly improves product reliability. reduce

Embodiment 1

[0018] like Figure 1-2 As shown, a new type of circuit breaker gear includes a switch base 1, a drive gear 4 is rotated on the switch base 1, a through hole is opened in the center of the drive gear 4, and a gear shaft 3 is connected to the through hole for rotation, and the switch base 1 is also rotated with a transmission gear 2 that meshes with the drive gear 4, and the transmission gear 2 is engaged with the drive worm 6 that is rotated on the switch base 1. The drive worm 6 is driven to rotate by the drive motor 5, and the shaft of the gear shaft 3 A fixed shaft 10 is arranged at the position close to the addendum circle of the driving gear 4 just above the center, and a stopper 7 is clamped on the fixed shaft 10. One end of the stopper 7 is located between two adjacent teeth of the drive gear 4, and one end of the stopper 7 is connected to The drive gear 4 constitutes a ratchet ratchet structure; the top of the fixed shaft 10 is provided with a closing half shaft 9, and...

Abstract

The invention discloses a novel circuit breaker gear, comprising a switch base, wherein a drive gear is rotatably arranged on the switch base, a through hole is opened in the center of the drive gear,a gear rotating shaft is rotatably connected in the through hole, a transmission gear meshed with the drive gear is also rotatably arranged on the switch base, the transmission gear is meshed with adrive worm that is rotatably arranged on the switch base, the drive worm is driven to rotate by a drive motor, a fixed shaft is arranged directly above the axis of the gear rotating shaft close to theaddendum circle of the drive gear, a stopper is clamped on the fixed shaft, and one end of the stopper is located between the adjacent two teeth of the drive gear; when the energy storage operation is performed, the drive gear rotates clockwise, the stopper is not stressed at this time, and the drive gear rotates normally; and when a one-way bearing fails or the load is too large, the elastic force of a spring may cause the whole transmission member to reverse, the stopper is stressed at this time, so that the drive gear and the transmission device cannot be reversed, the function can be realized, and the problem of manual reversion and fast energy storage can be quickly solved.

Description

technical field [0001] The invention relates to the field of gear equipment, in particular to a novel circuit breaker gear. Background technique [0002] A circuit breaker refers to a switching device that can close, carry and break current under normal circuit conditions and can close, carry and break current under abnormal circuit conditions within a specified time. Circuit breakers are divided into high-voltage circuit breakers and low-voltage circuit breakers according to their scope of use. The division of high and low voltage boundaries is relatively vague. Generally, those above 3kV are called high-voltage electrical appliances. Circuit breakers can be used to distribute electric energy, start asynchronous motors infrequently, protect power lines and motors, and automatically cut off the circuit when they are severely overloaded, short-circuited, or under-voltage. Its function is equivalent to a fuse-type switch. Combination with overheating and underheating relays, ...
