Description

Technical Field

[0001] This utility model relates to the field of power grid technology, specifically to the electric operation of a compact circuit breaker. Background Technology

[0002] A compact circuit breaker electric operator is an electrically operated mechanism used in conjunction with a compact circuit breaker. The compact circuit breaker electric operator is designed to optimize space layout, making the entire device very compact to save space. It is closely integrated with the compact circuit breaker as a whole. The electric operator part is usually connected to the circuit breaker's operating mechanism, which can accurately control the circuit breaker's opening and closing operations to ensure the normal operation of the circuit breaker.

[0003] Currently, in the use of compact circuit breakers, manual operation of the circuit breaker's opening and closing can easily cause electric shock hazards, reducing safety. Furthermore, excessive closing force can easily damage components and reduce their service life. Utility Model Content

[0004] The purpose of this utility model is to provide a compact circuit breaker operating mechanism to solve the problems mentioned in the background art, such as the risk of electric shock caused by manual operation of circuit breakers, which reduces safety, and the risk of damage to parts due to excessive closing force, which reduces the service life of parts. To achieve the above objective, this utility model provides the following technical solution: a compact circuit breaker operating mechanism, including a housing, with an electric component inside the housing. The electric component includes a connecting seat, which is fixedly connected to one side of the housing. A rotary motor is movably connected to the top of the connecting seat. A sector gear is fixedly connected to the transmission end of the rotary motor. A gear is meshed with one side of the sector gear. A rotating shaft is fixedly connected to one side of the gear. The rotating shaft is movably connected to the housing. A pull rod is fixedly connected to the side surface of the rotating shaft. A capacitor is fixedly connected to the inner wall of one side of the housing. An operational amplifier is fixedly connected to the inner wall of one side of the housing. A current detection block is fixedly connected to the inner wall of one side of the housing. With a fixed connection to the signal block, this compact circuit breaker is electrically operated. By adding an electric component, a rotating motor can be installed via a connector. The rotating motor drives a sector gear to rotate, which meshes with gear one, driving gear one and the rotating shaft to rotate. This, in turn, rotates the lever to complete the opening and closing of the circuit breaker without manual operation, improving safety. Furthermore, because the sector gear has a small meshing range, manually pulling the lever will not affect the rotating motor. The capacitor stores electricity when the circuit is connected, providing power to the rotating motor. The operational amplifier can adjust the direction and magnitude of the current, thereby controlling the rotational speed and direction of the rotating motor, achieving forward and reverse operation of the sector gear and adjusting the speed of the sector gear. After the current detection block detects the current magnitude, the closing force is reduced, extending the life of the components.

[0005] More preferably, the housing is provided with a rotating assembly, which includes a connecting rod, which is fixedly connected to one end of the rotating shaft, and a gear is fixedly connected to the side surface of the connecting rod.

[0006] More preferably, one side of the gear two is meshed with a gear shaft, which is movably connected to the inner wall of one side of the housing. A connecting rod two is fixedly connected to the side surface of the gear shaft, and a sliding rod is movably connected to the other end of the connecting rod two. In this compact circuit breaker operation, by adding a rotating component, the connecting rod one rotates with the rotating shaft, thereby driving the gear two to rotate, driving the gear shaft to rotate in the opposite direction, and driving the connecting rod two to rotate. The connecting rod two is movably connected to the sliding rod, and the length of the connecting rod two is fixed, driving the sliding rod to move in the arc-shaped groove. The sliding rod and the rotating rod one are fixedly connected by a fixed rod, which limits the sliding direction and range of the sliding rod, improving stability. Thus, the connection between the moving contact and the stationary contact is separated by the sliding rod, improving stability.

[0007] More preferably, an arc-shaped groove is formed on one inner wall of the housing, a sliding rod is movably connected inside the arc-shaped groove, a fixed rod is fixedly connected to the side surface of the sliding rod, and a rotating rod is fixedly connected to the other end of the fixed rod, the rotating rod being movably connected to the housing.

[0008] More preferably, the housing is provided with a connecting assembly, which includes a stationary contact fixedly connected to one side of the housing, a movable contact movably connected to one side of the stationary contact, a rotating frame fixedly connected to one side of the movable contact, and a rotating rod movably connected to one side of the rotating frame, the rotating rod being movably connected to the housing.

[0009] More preferably, a hook one is fixedly connected to one side of the rotating frame, a tension spring one is movably connected to one side of the hook one, and a hook two is movably connected to the other side of the tension spring one.

[0010] More preferably, a rotating rod three is fixedly connected to one inner wall of the housing, a rotating bar is movably connected to the other end of the rotating rod three, and an auxiliary rod is fixedly connected to one side of the rotating frame.

[0011] More preferably, a second tension spring is fixedly connected to one side of the rotating bar, a fuse is fixedly connected to the other end of the second tension spring, and a third tension spring is fixedly connected to the other side of the rotating bar.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] In this invention, the compact circuit breaker's electric operation, through the addition of an electric component, allows the rotary motor to be installed via a connecting bracket. The rotary motor drives a sector gear to rotate, which meshes with a connecting gear, causing the connecting gear and the rotating shaft to rotate. This, in turn, rotates the lever to complete the opening and closing of the circuit breaker without manual operation, improving safety. Furthermore, due to the small meshing range of the sector gear, manually pulling the lever will not affect the rotary motor. The capacitor stores electricity when the circuit is connected, providing power to the rotary motor. The operational amplifier can adjust the direction and magnitude of the current, thereby controlling the rotational speed and direction of the rotary motor, achieving forward and reverse rotation of the sector gear and adjusting its speed. After the current detection block detects the current magnitude, the closing force is reduced, extending the lifespan of the components.

[0014] In this utility model, the electric operation of this compact circuit breaker involves adding a rotating component. The connecting rod rotates with the rotating shaft, thereby driving the gear two to rotate, which in turn drives the gear shaft to rotate in the opposite direction, causing the connecting rod two to rotate. The connecting rod two is movably connected to the sliding rod, and the length of the connecting rod two is fixed, causing the sliding rod to move within the arc-shaped groove. The sliding rod and the rotating rod one are fixedly connected by a fixed rod, which limits the sliding direction and range of the sliding rod, improving stability. Thus, the connection between the moving contact and the stationary contact is separated by the sliding rod, further enhancing stability. Attached Figure Description
