For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0022] The technical solution of the utility model is further described in detail below in conjunction with the accompanying drawings and specific embodiments of the specification;

[0023] Embodiment 1: The present application provides an intelligent three-position circuit breaker, comprising a mechanism box 1; a microcomputer protection module 2 is installed on one side of the mechanism box 1, a display 3 is installed on the side of the microcomputer protection module 2, three sets of sealed poles 5 are installed on the front of the mechanism box 1, an isolating switch 4 is installed on the top of the sealed pole 5, a through-core current transformer 9 is installed on the bottom of the sealed pole 5, and a protective mechanism 10 is installed on the outside of the microcomputer protection module 2;

[0024] Specifically, Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, three groups of sealed poles 5 are arranged inside the mechanism box 1. The sealed poles 5 are used to connect cables or wires to specific positions in equipment or circuits, providing reliable electrical connections. The isolating switch 4 is used to establish electrical isolation between two circuits, that is, to completely cut off the electrical connection between the circuits, and the through-core current transformer 9 is used to accurately measure the current passing through its core to detect current abnormalities or overloads in the circuit. Once the current exceeds the set threshold, the protection device will be triggered and take appropriate measures, such as disconnecting the circuit or triggering an alarm to prevent equipment damage or circuit failure. By integrating the microcomputer protection module 2 and the through-core current transformer 9, various functional protections such as overcurrent, quick break, non-electrical quantity, over-voltage and under-voltage are realized. By integrating the live display 3, on-site wiring can be reduced, and the live condition is displayed on the circuit breaker intuitively and clearly, which is convenient for workers to watch, and the protection mechanism 10 is used to protect the microcomputer protection module 2.

[0025] Furthermore, a charged sensor 6 is installed on the front of the mechanism box 1 near the bottom of the sealed pole 5;

[0026] Specifically, Figure 1 , Figure 2 and Figure 3 As shown, in order to achieve overload protection for the device, the live sensor 6 is used to monitor the current flow in the circuit. It can detect the current size in real time. Once it is detected that the current exceeds the set threshold, it can trigger the protection action of the circuit breaker and quickly cut off the circuit to avoid malfunctions or safety hazards caused by current overload and prevent the circuit from being damaged due to overload.

[0027] Furthermore, a conductive clip installation position 8 is provided at the bottom of the front side of the sealed pole 5;

[0028] Specifically, Figure 1 , Figure 2 and Figure 3 As shown, in order to achieve circuit connection of the device, the conductive clip installation position 8 is used to install the conductive clip, which mainly affects the electrical connection quality, safety and reliability of the circuit breaker. It is used to connect the wires or cables in the power supply, load and control circuits. The conductive clip can ensure a low-resistance path for current transmission, reduce energy loss and heat, and ensure voltage stability in the circuit.

[0029] Furthermore, a grounding switch 7 is installed near the bottom of the sealed pole 5 in the mechanism box 1;

[0030] Specifically, Figure 1 , Figure 2 and Figure 3As shown, in order to avoid electric shock damage to the device, the grounding switch 7 is used to connect the metal casing and other conductive parts of the circuit breaker to the ground, ensuring that when a circuit breaker fails, any possible metal parts can quickly release the charge through the ground, thereby avoiding the risk of electric shock to personnel and equipment.

[0031] Furthermore, the protection mechanism 10 includes a heat conducting plate 1001 and a protection column 1002. The heat conducting plate 1001 is installed on the outside of the microcomputer protection module 2, and the protection column 1002 is installed on the outside of the heat conducting plate 1001.

[0032] Specifically, Figure 1 and Figure 2 As shown, in order to protect the device, the heat conducting plate 1001 is made of metal material and is arranged on the outer surface of the microcomputer protection module 2. The heat accumulated inside the microcomputer protection module 2 can be discharged through the heat conducting plate 1001 to avoid heat accumulation and reduce the service life of its internal electronic components. Multiple protective columns 1002 are arranged on the surface of the heat conducting plate 1001 to protect the microcomputer protection module 2 and avoid external collisions that may cause damage to its internal parts.

[0033] Furthermore, a filter 11 is installed at the bottom of the microcomputer protection module 2;

[0034] Specifically, Figure 2 As shown, in order to realize the anti-interference function of the device, the filter 11 is used to reduce the electromagnetic interference in the circuit and provide the stability of the power supply to prevent external signals from interfering with the operation of the device.

[0035] Working principle: Through the integration of microcomputer protection module 2 and core-through current transformer 9, various functional protections such as overcurrent, quick-break, non-electrical quantity, over-voltage and under-voltage, etc. can be realized. Through the integration of live display 3, on-site wiring can be reduced, and the live condition is displayed on the circuit breaker intuitively and clearly. At the same time, the live sensor 6 is used to monitor the current flow in the circuit. The grounding switch 7 is used to connect the metal casing and other conductive parts of the circuit breaker to the ground, ensuring that when the circuit breaker fails, any possible metal parts can quickly release the charge through the grounding to avoid the risk of electric shock to personnel and equipment.

[0036] Finally, it should be noted that the above specific implementation methods are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model is described in detail with reference to the embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified and replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
