Description

Technical Field

[0001] The utility model relates to the technical field of electrical equipment, in particular to an electric operating mechanism for a power distribution cabinet unit. Background Art

[0002] The functional unit room of the traditional structure of the power distribution cabinet is usually equipped with a hand-pulled push interlock mechanism, a manual opening and closing mechanism or an electric opening and closing mechanism.

[0003] The traditional electric opening and closing structure and the manual opening and closing structure cannot coexist, which is inconvenient to use. Moreover, when upgrading from manual operation to electric operation, the disassembly and assembly are complex. Summary of the Invention

[0004] The purpose of the utility model is to overcome the defects of the prior art and provide an electric operating mechanism with a simple structure, easy operation, material saving, convenient installation and upgrade, and can coexist with the manual operating mechanism.

[0005] To achieve the above purpose, the utility model adopts an electric operating mechanism for a power distribution cabinet unit, which relates to a drawer, a manual operating mechanism and a circuit breaker. The manual operating mechanism includes a handle switch and a square rod. The electric operating mechanism is characterized in that it includes a motor, a large gear shaft, a large gear, a small gear on the motor shaft, a controller and a fixed bracket; the fixed bracket is fixed on the bottom plate of the drawer, and the motor, the controller and a cover plate are fixed on it. The controller includes an initial position sensor; the large gear shaft is connected with the shaft hole of the fixed bracket and is inserted into the square rod, and includes a large gear shaft dial; the large gear is connected with the shaft hole of the large gear shaft and includes a lever A and a lever B; the lever A has an initial position facing the initial position sensor; the small gear on the motor shaft is sleeved on the motor shaft and meshes with the large gear. The controller is connected to the power supply, receives a control signal and controls the movement of the motor, and the square rod moves accordingly, so that the manual operating mechanism drives the operating mechanism of the circuit breaker to move.

[0006] Particularly, the control signal received by the controller can be transmitted by a wired signal or a wireless signal.

[0007] Particularly, the square rod drives the handle switch to move synchronously. The handle switch has an opening position and a closing position. The controller determines that the operating mechanism of the circuit breaker reaches the opening position, the closing position and the trip reset by detecting the current and the movement time of the motor.

[0008] Specifically, when the controller receives a tripping signal, the motor starts to rotate, driving the pinion on the motor shaft to rotate, thereby driving the large gear to start rotating. The lever A pushes the lever on the large gear shaft to move and stops when the circuit breaker operating mechanism reaches the tripping position. At this time, the motor starts to rotate, driving the large gear to rotate, causing the lever A to return to its initial position.

[0009] Specifically, when the controller receives a closing signal, at this time the motor starts to drive the pinion on the motor shaft to rotate, driving the large gear to start rotating. The lever B pushes the lever on the large gear shaft to move and stops when the circuit breaker operating mechanism reaches the closing position. At this time, the motor starts to rotate, driving the large gear to rotate, causing the lever A to return to its initial position. Description of the Drawings

Many specific details are set forth in the following description in order to fully understand the present invention. However, the present utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0016] Such as Figure 4As shown in the figure, the utility model adopts an electric operating mechanism for a power distribution cabinet unit, which involves a drawer (1), a manual operating mechanism (2), and a circuit breaker (3). The manual operating mechanism (2) includes a handle switch (4) and a square rod (5). A fixed bracket (12) is fixed on the bottom plate of the drawer (1). The large gear shaft (8) is inserted into and synchronously rotates with the square rod (5). When the square rod (5) rotates, the manual operating mechanism (2) drives the operating mechanism of the circuit breaker (3) to move. The square rod (5) drives the handle switch (4) to move synchronously. The handle switch (4) has an opening position and a closing position. When the motor (7) moves, the square rod (5) moves accordingly.

[0017] As Figure 1 , 2 , 3, the electric operating mechanism (6) includes a motor (7), a large gear shaft (8), a large gear (9), a motor shaft pinion (10), a controller (11), and the fixed bracket (12); the motor (7), the controller (11), and a cover plate (17) are fixed on the fixed bracket (12). The controller (11) includes an initial position sensor (13); the large gear shaft (8) is connected to the fixed bracket (12) through a shaft hole and includes a large gear shaft lever (14); the large gear (9) is connected to the large gear shaft (8) through a shaft hole and includes a lever A (15) and a lever B (16); the lever A (15) has an initial position facing the initial position sensor (13); the motor shaft pinion (10) is sleeved on the shaft of the motor (7) and meshes with the large gear (9). The controller (11) is connected to a power source, receives a control signal, and controls the movement of the motor (7). The control signal received by the controller (11) can be transmitted through a wired signal or a wireless signal.

[0018] As Figure 1 , 2, 3, 4, the controller (11) determines that the operating mechanism of the circuit breaker (3) reaches the opening position, closing position and trip reset by detecting the current and movement time of the motor (7). When the controller (11) receives a tripping signal, the motor (7) starts to rotate, driving the pinion gear (10) of the motor shaft to rotate, thereby driving the large gear (9) to start rotating. The lever A (15) pushes the lever on the large gear shaft (14) to move, and stops when the operating mechanism of the circuit breaker (3) reaches the opening position. At this time, the motor (7) starts to rotate, driving the large gear (9) to rotate, and making the lever A (15) return to the initial position. When the controller (11) receives a closing signal, at this time the motor (7) starts to drive the pinion gear (10) of the motor shaft to rotate, driving the large gear (9) to start rotating. The lever B (16) pushes the lever on the large gear shaft (14) to move, and stops when the operating mechanism of the circuit breaker (3) reaches the closing position. At this time, the motor (7) starts to rotate, driving the large gear (9) to rotate, and making the lever A (15) return to the initial position.
