[0023] The preferred embodiments of this utility model will be described in detail below to provide a clearer understanding of its purpose, features, and advantages. It should be understood that the following embodiments are not intended to limit the scope of this utility model, but are merely illustrative of its essential spirit.

[0024] In the following description, certain specific details are set forth for the purpose of illustrating various disclosed embodiments in order to provide a thorough understanding of the various disclosed embodiments. However, those skilled in the art will recognize that embodiments may be practiced without one or more of these specific details. In other instances, well-known techniques associated with this application may not have been shown or described in detail to avoid unnecessarily obscuring the description of the embodiments.

[0025] 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.

[0026] As shown in Figures 1 to 4, the intelligent power distribution module connection device for molded case circuit breakers of this utility model includes a conventional molded case circuit breaker 1 and an intelligent power distribution module connection device 2, wherein the conventional molded case circuit breaker 1 and the intelligent power distribution module connection device 2 are rigidly connected by a rectangular copper busbar 3.

[0027] The intelligent power distribution module connection device 2 includes an intelligent power distribution module housing, a precise metering module, a multi-directional protection module, and an Ethernet communication module. The precise metering module, multi-directional protection module, and Ethernet communication module are all installed inside the intelligent power distribution module housing. The upper end of the intelligent power distribution module housing connects to the output terminal of the conventional molded case circuit breaker 1, while its lower end is reserved for field connection of cables or copper busbars.

[0028] The rectangular copper busbar 3 is rigidly connected to the output terminal of the conventional molded case circuit breaker 1 by bolt fixing. The embedded shell structure can be seamlessly matched with the conventional molded case circuit breaker 1 to meet the requirements of electrical clearance and creepage distance.

[0029] The other end of the intelligent power distribution module connection device 2 facilitates on-site connection of outgoing cables or copper busbars.

[0030] The precise metering module and the multi-directional protection module are connected via a signal transmission line, which is laid through a partition inside the intelligent power distribution module housing for isolation. The Ethernet communication module is located at the front end of the intelligent power distribution module housing.

[0031] During operation, current flows from the terminals of the conventional molded case circuit breaker 1 through the rectangular copper busbar 3 to the input terminals of the intelligent power distribution module connection device 2. Internally installed voltage and current sensors continuously collect power data via a chip. A precise metering module then accurately measures the collected power data. An Ethernet communication module enables Ethernet communication, while a multi-directional protection module provides multi-directional protection for the circuit. Employing core components such as a microprocessor, it collects current and voltage signals in the circuit in real time, performs intelligent analysis and judgment, and issues a trip signal to control the circuit breaker operation when an abnormality occurs, based on set protection parameters and algorithms. The multi-directional protection module can provide multiple protection functions, including overcurrent, overvoltage, undervoltage, and phase loss, and also features a delay function. Different delay times can be set according to the severity of different fault types and protection requirements.

[0032] Working principle;

[0033] The intelligent power distribution module connection device for molded case circuit breakers of this utility model mainly consists of a conventional molded case circuit breaker 1, an intelligent power distribution module connection device 2, and a rectangular copper busbar 3. The intelligent power distribution module connection device 2 includes an intelligent power distribution module housing, a precision metering module, a multi-directional protection module, and an Ethernet communication module.

[0034] Current flows from the terminals of the conventional molded case circuit breaker 1 through the rectangular copper busbar 3 to the input terminals of the intelligent power distribution module connection device 2. The precision metering module accurately measures the current, converts the current signal into a digital signal, and transmits the data to the multi-directional protection module via a signal transmission line. The multi-directional protection module monitors and analyzes the received current data in real time. When an abnormal current is detected, it reacts quickly, triggering the protection mechanism to disconnect the circuit and protect the equipment and lines. Simultaneously, the multi-directional protection module also transmits the current data and protection status information to the Ethernet communication module via an internal communication line to achieve remote monitoring and data transmission functions.

[0035] Work process;

[0036] When a traditional molded case circuit breaker 1 is energized, current is output from the terminals. The current is transmitted through a rectangular copper busbar 3 to the input terminals of the intelligent power distribution module connection device 2. A precision metering module accurately measures the input current and converts the current signal into a digital signal. This digital signal is transmitted to a multi-directional protection module via a signal transmission line. The multi-directional protection module monitors and analyzes the current data in real time to determine if the current is normal. If the current is normal, the multi-directional protection module transmits the current data and normal status information to the Ethernet communication module via its internal communication line. If the current is abnormal, the multi-directional protection module immediately triggers the protection mechanism, disconnects the circuit, and transmits the fault information to the Ethernet communication module via its internal communication line. The Ethernet communication module then sends the received information to the remote monitoring system through its communication interface, enabling remote monitoring and data transmission.

[0037] Connection method;

[0038] A conventional molded case circuit breaker 1 is installed inside the distribution box. The intelligent power distribution module connection device 2 is then placed below the conventional molded case circuit breaker 1, and bolts are used to ensure a tight connection between the intelligent power distribution module housing and the conventional molded case circuit breaker 1, guaranteeing the electrical performance and safety of the connection. One end of a rectangular copper busbar 3 is bolted to the terminal block of the conventional molded case circuit breaker 1, and the other end is bolted to the input terminal of the intelligent power distribution module connection device 2, ensuring a good power connection. The signal transmission line between the precision metering module and the multi-directional protection module is laid through an internal partition of the intelligent power distribution module housing for isolation, reducing signal interference and improving signal transmission stability. An Ethernet communication module is installed at the front end of the intelligent power distribution module housing to enable remote communication.
