Description

Technical Field

[0001] This utility model relates to the field of electrical equipment, specifically to a 2P~4P traditional miniature circuit breaker intelligent power distribution module connection device. Background Technology

[0002] Traditional 2P to 4P miniature circuit breakers are widely available on the market, but they have significant functional limitations. Currently, these traditional circuit breakers mainly provide overload and short-circuit protection, making it difficult to meet the demands of modern electrical systems for intelligent and multifunctional equipment. For example, in applications requiring precise current and voltage measurement, as well as remote monitoring, traditional circuit breakers fall short.

[0003] To achieve functions such as accurate metering, multi-directional protection, and Ethernet communication on the basis of traditional circuit breakers, the conventional approach is to use external measurement, display, integrated protection, and communication modules. However, this approach has many drawbacks: First, it significantly increases the overall unit size, making the layout of distribution boxes and other equipment more difficult and reducing space utilization; second, it reduces economic practicality, as the purchase, installation, and maintenance costs of external modules are high, and compatibility issues between components may lead to frequent failures, further increasing operating costs.

[0004] Furthermore, although some intelligent miniature circuit breakers have appeared on the market, they are often only compatible with each manufacturer's own products, resulting in poor versatility. This significantly limits users' choices and replacements, making it difficult to achieve compatibility and collaborative operation between different brands and models, and hindering the large-scale adoption of intelligent miniature circuit breakers.

[0032] Throughout this specification, references to "an embodiment" or "an embodiment" indicate that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment. Therefore, the appearance of "in an embodiment" or "in an embodiment" in various places throughout the specification does not necessarily refer to the same embodiment. Furthermore, a particular feature, structure, or characteristic may be combined in any way in one or more embodiments.

[0033] like Figure 1 and Figure 2 As shown, this utility model provides a 2P~4P conventional miniature circuit breaker intelligent power distribution module connection device, including a 2P~4P conventional miniature circuit breaker 1, an intelligent power distribution module connection device 2, and a dovetail base 4, which are arranged horizontally for communication operations. The intelligent power distribution module connection device 2 is connected and fixed to the 2P~4P conventional miniature circuit breaker 1 via a circular copper rod 3. The dovetail base 4 is located below the intelligent power distribution module connection device 2 to accommodate 2P~4P conventional miniature circuit breakers 1 with different connection heights.

[0034] The intelligent power distribution module connection device 2 integrates a metering module, an intelligent protection module, and a communication module. The metering module accurately measures electrical parameters such as current, voltage, and power. The intelligent protection module provides multiple protection functions, including overcurrent, overvoltage, undervoltage, and phase loss protection, and features a time delay function, allowing for different delay times to be set according to the severity of different fault types and protection requirements. The communication module supports Ethernet communication, enabling remote monitoring and data transmission. The circuit design of each module is compatible with the connection lines of a 2P~4P traditional miniature circuit breaker 1, ensuring normal functional operation.

[0035] The dovetail base 4 is available in different thicknesses. By replacing different dovetail bases 4 with different thicknesses, miniature circuit breakers of 2P, 3P, and 4P structural types can be matched.

[0036] The circular copper rod 3 is rigidly connected to the intelligent power distribution module connection device 2 and the 2P~4P conventional miniature circuit breaker 1. The connection between the circular copper rod 3 and the intelligent power distribution module connection device 2 is provided with reinforcing ribs. At the same time, the circular copper rod 3 is also inserted into the output terminal of the 2P~4P conventional miniature circuit breaker 1 for a tight connection.

[0037] It can be matched with 2P, 3P, and 4P miniature circuit breakers. In practical applications, according to the height specifications of the 2P~4P traditional miniature circuit breaker 1 used, a suitable dovetail base 4 is selected and fixed below the intelligent power distribution module connection device 2. Then, the intelligent power distribution module connection device 2 is connected to the 2P~4P traditional miniature circuit breaker 1 through the round copper rod 3 to complete the installation of the device.

[0038] In practice, when a traditional distribution box needs to be upgraded to be intelligent, the connection device of this utility model can be installed on an existing 2P~4P traditional miniature circuit breaker 1 without replacing the entire distribution box or circuit breaker, which greatly saves costs and construction time. After installation, the traditional miniature circuit breaker can have functions such as accurate metering, multi-directional protection, and Ethernet communication, improving the intelligence level and operating efficiency of the power distribution system.

[0039] Working principle;

[0040] The core of this device lies in the coordinated operation of the intelligent power distribution module connection device 2 and the miniature circuit breaker. The intelligent power distribution module connection device 2 integrates a metering module, an intelligent protection module, and a communication module. When the device is connected to the miniature circuit breaker, current flows from the miniature circuit breaker through the circular copper rod 3 into the intelligent power distribution module connection device 2. The metering module accurately measures electrical parameters such as current, voltage, and power, and transmits the data to the communication module. This data is then sent to external monitoring equipment via the Ethernet communication interface on the side, enabling remote monitoring and data analysis. The intelligent protection module monitors the circuit operation in real time. Upon detecting abnormalities such as overcurrent, overvoltage, undervoltage, or phase loss, it quickly sends a signal, triggering the miniature circuit breaker to disconnect the circuit, thus achieving multi-faceted protection.

[0041] Work process;

[0042] Installation preparation: Select a suitable dovetail base 4 according to the specifications of the 2P~4P traditional miniature circuit breaker 1 used, and ensure that all modules of the intelligent power distribution module connection device 2 have been installed and debugged, and that the Ethernet communication interface is available.

[0043] Connection device: The dovetail base 4 is fixed below the intelligent power distribution module connection device 2, so that the dovetail part at the bottom of the intelligent power distribution module connection device 2 is embedded in the dovetail groove of the dovetail base 4, realizing a detachable connection. Then, the circular copper rod 3 is rigidly connected to the intelligent power distribution module connection device 2 and the 2P~4P conventional miniature circuit breaker 1, and a reinforcing rib is installed at the connection to ensure the stability of the connection. At the same time, the circular copper rod is inserted into the output terminal of the 2P~4P conventional miniature circuit breaker for a tight connection.

[0044] Electrical connection: Connect the intelligent power distribution module connection device 2 to the 2P~4P conventional miniature circuit breaker 1 with a wire, and the wire will be electrically connected to the metering module and intelligent protection module inside the intelligent power distribution module connection device 2 to ensure good electrical connection.

[0045] Commissioning and Operation: After connection is complete, the entire device is commissioned to check whether each module is working properly and whether the communication interface can establish a connection with external monitoring equipment. Once commissioning is complete, the device can be put into operation. During operation, the metering module monitors electrical parameters in real time and transmits data to external monitoring equipment via the communication module; the intelligent protection module uses core components such as a microprocessor to collect current, voltage, and other signals in the circuit in real time, performing intelligent analysis and judgment. Based on the set protection parameters and algorithms, when an abnormal situation occurs, a trip signal is issued to control the circuit breaker to operate.

[0046] Connection method;

[0047] Dovetail base connection: The dovetail groove of the dovetail base 4 is adapted to the dovetail portion at the bottom of the intelligent power distribution module connection device 2. During installation, align the dovetail portion at the bottom of the intelligent power distribution module connection device 2 with the dovetail groove of the dovetail base 4, and then slowly push it in along the direction of the groove until the intelligent power distribution module connection device 2 is fully embedded in the dovetail base 4, achieving a detachable connection. This connection method utilizes the special shape of the dovetail groove and the dovetail portion to ensure the tightness and stability of the connection, while facilitating installation and disassembly, thus improving work efficiency.

[0048] Circular copper rod connection: Circular copper rod 3 is rigidly connected to the intelligent power distribution module connection device 2 and the 2P~4P conventional miniature circuit breaker 1. Before rigid connection, it must be ensured that the size of the circular copper rod 3 matches the connection points of the intelligent power distribution module connection device 2 and the miniature circuit breaker. Simultaneously, reinforcing ribs are provided at the connection point between the circular copper rod 3 and the intelligent power distribution module connection device 2, and the circular copper rod 3 is inserted into the output terminal of the 2P~4P conventional miniature circuit breaker 1 for a tightening effect, further enhancing the stability of the connection and preventing loosening or damage due to external forces, ensuring stable operation of the device during long-term use.

[0049] Based on the above working principle, workflow, and connection method, the 2P~4P traditional miniature circuit breaker 1 intelligent power distribution module connection device of this utility model can effectively combine traditional miniature circuit breakers with intelligent power distribution modules to achieve functions such as accurate metering, multi-directional protection, and Ethernet communication, thereby improving the intelligence level and practicality of the circuit breaker, meeting the needs of modern electrical systems, and reducing the transformation cost and construction difficulty. It has broad application prospects and market value.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
