Description

Technical Field

[0001] This invention belongs to the field of circuit breaker technology, specifically relating to a modular miniature circuit breaker with remote control function. Background Technology

[0002] With the standardization and improved stability of circuit breakers, their applications are becoming increasingly widespread. They can be used in all power distribution scenarios in residential, industrial, and commercial settings, making them one of the most widely used safety devices. They are also an important automatic control device. They have two main uses: first, a control function, which involves switching on or off certain equipment or lines according to the needs of the power grid; second, a protection function, which involves automatically and quickly disconnecting faulty components or lines from the operating system when a fault occurs, preventing further damage to the faulty components and ensuring that the fault-free parts can quickly return to normal operation.

[0003] Currently, miniature circuit breakers with automatic opening and closing and remote control functions need to be equipped with an electric operating mechanism (referred to as electric operator) to achieve automatic opening and closing or remote control of the miniature circuit breaker. However, the electric operating mechanisms are usually implemented as independent accessories or arranged side by side in the width direction of the miniature circuit breaker, which increases the width and size of the miniature circuit breaker. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of traditional miniature circuit breakers, which require the electric operating mechanism to be a separate accessory or arranged side-by-side along the width of the miniature circuit breaker, thus increasing its size. The invention proposes a modular miniature circuit breaker with remote control functionality, integrating the electric operating mechanism. This eliminates the need for an additional electric operating mechanism, enabling remote control and significantly reducing the size of the miniature circuit breaker. The entire miniature circuit breaker has a compact structure while simultaneously expanding its functionality.

[0007] Furthermore, the housing is also equipped with a rotating swing arm, the drive transmission mechanism and the electromagnetic system are respectively linked to the rotating swing arm, the rotating swing arm is linked to the operating mechanism, and the drive transmission mechanism or the electromagnetic system can drive the rotating swing arm to link with the operating mechanism to realize the circuit breaker's opening or tripping operation.

[0008] Furthermore, the rotating swing arm is rotatably mounted inside the housing of the outer casing. The rotating swing arm is provided with a drive linkage arm that is linked with the gear set in the drive transmission system. The rotating swing arm is provided with an electromagnetic linkage arm that is linked with the electromagnetic system. The rotating swing arm is provided with an operating mechanism linkage arm that cooperates with the latch in the operating mechanism to realize the circuit breaker's opening or tripping operation.

[0009] Furthermore, the drive transmission mechanism includes a motor and a gear set, which are located in the lower left part of the outer casing. One end of the gear set is connected to the handle in the operating mechanism, and the other end is connected to the motor.

[0010] Furthermore, the data acquisition module is integrated inside the housing of the miniature circuit breaker, and the data acquisition module, drive transmission system, operating mechanism, contact system, electromagnetic system, and arc extinguishing system are arranged on the same plane.

[0011] Furthermore, the data acquisition module is fixed to the upper and lower ends of the miniature circuit breaker as an independent accessory.

[0012] Furthermore, the electromagnetic system and the arc-extinguishing system are located at the lower right of the miniature circuit breaker, on the right side of the drive transmission mechanism.

[0013] Furthermore, the operating mechanism is located on the upper right side of the circuit breaker. It can be operated manually via a handle and electrically via a drive transmission system. The two operating modes operate independently and do not affect each other.

[0014] Furthermore, the contact system includes a moving contact and a stationary contact, the moving contact being connected to the operating mechanism and the stationary contact being connected to the electromagnetic system;

[0015] Furthermore, the data acquisition module collects relevant electrical parameter information of the miniature circuit breaker through the current transformer and transmits it to the intelligent controller.

[0023] Example

[0024] Currently, miniature circuit breakers with automatic opening and closing and remote control functions require an electric operating mechanism (referred to as electric operator) to achieve automatic opening and closing or remote control of the miniature circuit breaker. However, most common electric operating mechanisms are implemented as independent accessories or arranged side by side along the width of the miniature circuit breaker, increasing the width and size of the miniature circuit breaker. To solve this problem, as shown in the attached... Figure 1As shown in the figure, this embodiment provides a modular miniature circuit breaker with remote control function, featuring overload protection and short-circuit protection. Combined with an intelligent controller, it can achieve data interaction and remote control functions. The miniature circuit breaker includes a housing 1, within which are installed an operating mechanism 2, a contact system 3, an electromagnetic system 4, and an arc-extinguishing system 5. It also includes a drive transmission system 6, which is arranged on the same plane as the operating mechanism 2, contact system 3, electromagnetic system 4, and arc-extinguishing system 5. Simultaneously, a data acquisition module 7 is integrated inside the housing 1 of the miniature circuit breaker. The data acquisition module 7, drive transmission system 6, operating mechanism 2, contact system 3, electromagnetic system 4, and arc-extinguishing system 5 are also arranged on the same plane (i.e., located on the same plane to ensure the width dimension of the miniature circuit breaker remains unchanged). The data acquisition module 7 can collect relevant electrical parameter information of the miniature circuit breaker during operation through a current transformer and transmit it to the intelligent controller, including but not limited to voltage, current, and frequency.

[0025] Specifically, as shown in the attached document. Figure 1 As shown, in this embodiment, the operating mechanism 2 is located in the upper right part of the housing 1. The operation includes both manual and electric modes, which operate independently and do not affect each other. In the manual mode, the handle 201 is driven directly by human power to drive the operating mechanism and achieve the opening and closing operation. In the electric mode, the handle 201 is driven by the drive transmission mechanism 6, or the rotating swing arm 8 is driven by the drive transmission mechanism 6 to achieve the opening and closing operation. The contact system 3 consists of a moving contact 301 and a stationary contact 302. The moving contact 301 is connected to the operating mechanism 2, and the stationary contact 302 is connected to the electromagnetic system 4. The electromagnetic system 4 and the arc-extinguishing system 5 are located in the lower right part of the miniature circuit breaker, to the right of the drive transmission mechanism 6. In this embodiment, both the electromagnetic system 4 and the arc-extinguishing system 5 are vertically arranged and horizontally arranged side-by-side.

[0026] The drive transmission mechanism 6 includes a motor 602 and a gear set 601. The motor 602 and the gear set 601 are located in the lower left part of the housing 1. One end of the gear set 601 is connected to the handle 201 in the operating mechanism 2, and the other end is connected to the motor 602. The motor 602 provides driving force, which is transmitted through the gear set 601 to drive the handle 201 or the rotating swing arm 8 to drive the operating mechanism to realize the opening and closing operation.

[0027] The rotating swing arm 8 is mounted inside the housing 1. The drive transmission mechanism 6 and the electromagnetic system 4 are respectively linked to the rotating swing arm 8. The rotating swing arm 8 is linked to the operating mechanism 2. The drive transmission mechanism 6 or the electromagnetic system 4 can drive the rotating swing arm 8 to link with the operating mechanism 2 to realize the circuit breaker's opening or tripping operation. Specifically, in this embodiment, the rotating swing arm 8 is rotatably mounted inside the housing 1. The rotating swing arm 8 is provided with a drive linkage arm 801 that is linked with the gear set 601 in the drive transmission system 6. The rotating swing arm 8 is provided with an electromagnetic linkage arm 802 that is linked with the electromagnetic system 4. The rotating swing arm 8 is provided with an operating mechanism linkage arm 803 that cooperates with the latch 202 in the operating mechanism 2 to realize the circuit breaker's opening or tripping operation.

It can realize the remote control function without the need for an additional electric operating mechanism, greatly reducing the size of the miniature circuit breaker. The entire miniature circuit breaker has a compact structure and expands the functionality of the miniature circuit breaker.
