Description

Technical Field

[0001] This utility model relates to the field of circuit breaker technology, and in particular to a circuit breaker with ground wire monitoring and N-phase voltage metering functions. Background Technology

[0002] Traditional circuit breakers typically only connect to three-phase lines (A, B, and C), lacking effective monitoring and protection capabilities for the N-phase (neutral) voltage. They cannot detect abnormal N-phase voltage in real time. In actual power use, issues such as loose connections, breaks, poor contact, or abnormal voltage on the N-phase can damage electrical equipment or even cause fires. Traditional circuit breakers cannot identify and automatically trip in such situations, posing significant safety hazards. Therefore, this solution proposes a circuit breaker with ground wire monitoring and N-phase voltage metering functions to address these problems. Summary of the Invention

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] This utility model provides, for example Figure 1 The circuit breaker shown includes a ground wire monitoring and N-phase voltage metering function, comprising:

[0019] The circuit breaker body 1 includes phase poles, and an N-phase 104 is provided on one side of the phase poles.

[0020] Grounding wire 2 is electrically connected to the grounding terminal of the circuit breaker body 1;

[0021] Communication line 4 is electrically connected to the communication terminal of the circuit breaker body 1.

[0022] Intelligent gateway 3 is electrically connected to the end of communication line 4 away from circuit breaker body 1. Intelligent gateway 3 is used to control the opening and closing of circuit breaker body 1.

[0023] The display component is connected to the output of the smart gateway 3.

[0024] The phase pole includes a C phase 103 disposed on one side of the N phase 104, a B phase 102 disposed on one side of the C phase 103, and an A phase 101 disposed on one side of the B phase 102.

[0025] It should be noted that phases A (101), B (102), and C (103) on the circuit breaker are the three live wires in a three-phase AC power system. Their voltage phases differ by 120 degrees, and they collectively undertake the main power transmission task, supplying power to high-power equipment and three-phase motors. Phase N (104) (neutral wire) is the neutral wire, providing a common return path for the three-phase current. Ideally, it maintains zero potential to form a working circuit and balance the voltage of the three-phase load. These four wires work together to ensure the stability and safety of the power supply system, while the circuit breaker provides integrated on / off control and protection. The intelligent gateway 3 is configured for existing equipment. The intelligent gateway 3 is the core hub of the intelligent power distribution system. It is connected to the intelligent circuit breaker with communication function through the communication line 4, and plays the dual role of "data relay station" and "local brain". The communication line 4 is the existing RS485 communication line 4, which is a dedicated physical link responsible for stable and real-time data transmission between the circuit breaker body 1 and the intelligent gateway 3. This cable not only provides the intelligent gateway 3 with a channel for remote status monitoring, parameter setting and opening and closing control of the circuit breaker body 1, but also provides the hardware foundation for realizing local edge computing and fast linkage protection, ensuring the real-time performance and stability of the entire intelligent power distribution system in complex industrial environments.

[0026] Furthermore, compared to traditional circuit breakers, it has the ability to simultaneously connect phase A 101, phase B 102, phase C 103 and phase N 104, and has additionally developed a grounding wire 2 interface, which can realize the metering function of N pole voltage. The data obtained by monitoring the new circuit breaker can be further edited for strategy, realizing local control of the circuit breaker to trip under abnormal voltage, effectively avoiding the circuit burnout problem caused by the inability to automatically disconnect short circuits.

[0027] Specifically, the display component includes a mobile phone 6 installed at the output end of the smart gateway 3. A transmission component is installed at the connection between the smart gateway 3 and the mobile phone 6. The transmission component includes an operation and maintenance platform 5 that is connected to the output end of the smart gateway 3. The mobile phone 6 is connected to the output end of the operation and maintenance platform 5.

[0028] It should be noted that the 4G transmission module is embedded in the gateway, which uses the cellular network to securely and reliably transmit data remotely to the operation and maintenance platform 5, breaking geographical limitations; the operation and maintenance platform 5 is the cloud brain, responsible for the storage, analysis and visualization of massive amounts of data, and supports policy distribution and big data management; the APP pushes alarm information and key data to the user's mobile phone 6 in real time.

[0029] Furthermore, during use, the intelligent gateway 3, as the core data hub of the field equipment, is responsible for real-time collection and protocol conversion of the circuit breaker body 1's operating data. The intelligent gateway 3, through its built-in 4G module, uses a high-speed mobile network to stably and securely transmit this data remotely to the cloud-based operation and maintenance platform 5. The operation and maintenance platform 5 stores, analyzes, and processes the data to achieve equipment status monitoring, energy efficiency management, and fault early warning. Users can receive real-time push notifications of alarm information and operation reports through the APP on their mobile phones 6, and remotely view the equipment status and execute control operations at any time, thereby realizing the mobility, intelligence, and efficiency of equipment operation and maintenance.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
