Description

Technical Field

[0001] The present invention relates to the technical field of power systems, and particularly to a circuit breaker opening and closing control gateway and method. Background Art

[0002] A circuit breaker opening and closing control gateway is a device specifically designed for power systems, especially in the fields of distribution automation and smart grids. It is mainly used for remotely monitoring and controlling the opening (disconnecting) and closing (closing) operations of power equipment such as circuit breakers and switches. Such gateways usually integrate multiple functions to ensure the reliability and security of the power system and are compatible with different communication protocols and technologies. The main functions of the circuit breaker opening and closing control gateway include remote control, status monitoring, fault diagnosis and alarm, data processing and analysis, security mechanisms, and protocol conversion, etc. Remote control allows operators to remotely open or close power equipment through a network connection, supporting multiple communication methods such as Ethernet, GPRS, 4G / 5G cellular networks, Wi-Fi, etc., for flexible access to different control systems; status monitoring is used to collect and transmit the status information of power equipment in real time, including parameters such as current, voltage, and temperature; fault diagnosis and alarm can detect abnormal conditions such as overload and short circuit and send alerts to relevant personnel in a timely manner; data processing and analysis is to preliminarily process and analyze the collected data to generate reports or trend charts to assist in decision-making; security mechanisms ensure the security of the system and data privacy by integrating functions such as identity authentication, permission management, and encrypted communication; protocol conversion acts as a bridge between different types of power equipment to achieve interoperability between them.

[0003] In order not to affect power supply, the opening and closing usually design a control gateway with a reclosing function. There is a reclosing mechanism inside the gateway. After detecting an instantaneous fault, the reclosing mechanism automatically closes the circuit breaker again to restore power supply.

[0004] Most traditional reclosing mechanisms are controlled by a single switch without corresponding safeguard mechanisms, and are prone to misoperation, causing the opening and closing of the circuit without eliminating the fault to be closed again, posing a safety hazard.

At this time, switch S2 is disconnected to prevent the fault classification module from malfunctioning and sending an incorrect instruction to close switch S3, causing the circuit of the relay mechanism 4 to be always energized and wasting electric energy.

[0055] Among them, adjust the outer rod 423 so that its right end is located in the guiding groove 28. Press the push block 421 inward to compress the push rod spring 424. The outer rod 423 abuts against the other end of the push rod spring 424, and the push rod spring 424 contracts. The push block 421 enters the corresponding guiding groove 28. Push the housing 41 upward. When the convex strip 46 enters the arc-shaped groove 24, the outer rod 423 moves to the front of the limiting groove 29. The push rod spring 424 resumes elongation and pushes the right end of the outer rod 423 into the limiting groove 29. At the same time, the outer rod 423 drives the bent rod 427 to move rightward through the vertical block 426, and inserts the bent rod 427 into the slot 26. The bent rod 427 and the right end of the outer rod 423 fix the housing 41 on the bottom plate 21 at both ends, together with the convex strip 46, strengthening the connection strength between the relay mechanism 4 and the support mechanism 2.

[0059] In one embodiment, referring to Figure 3 As shown, the support mechanism 2 includes a bottom plate 21, a support plate 22, a through groove 23, an arc-shaped groove 24 and a convex block 25. The support plate 22 is fixedly provided at both ends of the bottom plate 21. The support plate 22 is fixedly connected to the switching-on and switching-off body 1. The bottom plate 21 and the two support plates 22 enclose a notch for accommodating the relay mechanism 4. The through groove 23 penetrates through the bottom plate 21. The arc-shaped groove 24 is located on both sides of the through groove 23. The convex block 25 is located in the through groove 23. The convex block 25 is fixedly connected to the bottom plate 21. Preferably, the cross section of the convex block 25 is triangular, which reduces the contact area with the spring piece 51 and facilitates the spring piece 51 to slide along the convex block 25.

[0060] In one embodiment, referring to Figure 4As shown, the support mechanism 2 further includes a limit groove 29 assembly. The limit groove 29 assembly includes a slot 26, a T-shaped groove 27, a guide groove 28, a limit groove 29, and a rectangular groove 30. The T-shaped groove 27 is located inside the support plate 22. The guide groove 28 is located outside the T-shaped groove 27. The limit groove 29 is located outside the top of the T-shaped groove 27. The limit groove 29 communicates with the guide groove 28. The slot 26 and the rectangular groove 30 are located on the lower surface of the bottom plate 21 and communicate with each other. The slot 26 is adapted to the bent rod 427.

[0061] In one embodiment, referring to Figure 5 As shown, the rotating mechanism 3 includes a brake post 31, a connecting rod 32, a handle 33, a contact handle 34, and a convex post 35. The brake post 31 is rotatably provided between the support plates 22. One end of the connecting rod 32 is fixedly connected to the brake post 31, and the other end is fixedly connected to the handle 33. The contact handle 34 is fixedly connected to the connecting rod 32. The convex post 35 is fixedly connected to the contact handle 34. Preferably, the contact handle 34 is made of a permanent magnet. The convex post 35 is fixedly provided below the contact handle 34. A terminal is provided on the outer edge of the brake post 31. When the handle 33 rotates upward, the terminal contacts the main circuit, and the main circuit forms a path. When the handle 33 rotates downward, the terminal leaves the main circuit, and the main circuit is disconnected.

[0062] The working principle of the on-off control gateway of this circuit breaker: Install the on-off body 1 in the main circuit. Push the handle 33 to drive the connecting rod 32 to drive the brake column 31 to rotate upward. When the handle 33 rotates to the uppermost position, the on-off body 1 closes and the main circuit is connected at this time. Hold the handle below the relay mechanism 4 and place the relay mechanism 4 below the support mechanism 2 so that the clamping components 43 are respectively facing the card slots on the inner side below the support plate 22. At this time, the protective shell 44 is facing the through slot 23, the convex block 25 is facing the groove 45. Push the relay mechanism 4 upward, and the clamping components 43 enter the card slots, and the protective shell 44 enters the through slot 23. As the protective shell 44 moves upward, the convex block 25 squeezes the first trigger part in the groove 45, causing the bending piece 53 to rotate inward around the top of the elastic piece 51. When the protective shell 44 completely enters the through slot 23, the elastic piece 51 rotates to the maximum displacement, and the bending piece 53 touches the contact in the groove 45, and the switch S1 closes at this time; when the convex strip 46 enters the through slot 23 and is squeezed and deformed, and it enters the arc-shaped groove 24 along the through slot 23, the pressure on the convex strip 46 becomes smaller, and the convex strip 46 rebounds and is stuck in the arc-shaped groove 24 to fix the relay mechanism 4 on the support mechanism 2; when a fault occurs in the main circuit, the on-off automatically disconnects, the handle 33 rotates downward, the contact handle 34 presses on the protective shell 44, and at the same time the convex column 35 pushes the column body 61 downward, and the elastic member 62 contracts. When the column body 61 touches the contact at the top of the housing 41, the switch S2 closes; the fault classification module in the on-off detects the fault type of the main circuit. If it is an instantaneous fault such as a short circuit caused by lightning strikes or birds touching the wire, after the fault is eliminated, the fault classification module sends an instruction to the switch S3, the switch S3 closes, the circuit of the relay mechanism 4 is connected, and the electromagnet in the protective shell 44 generates magnetism. At the moment when the circuit of the relay mechanism 4 is connected, the instantaneous magnetism of the electromagnet is stronger, and the magnetic poles of the part in contact with the contact handle 34 are the same, and the two generate a strong repulsive force to push the contact handle 34 upward. The contact handle 34 drives the connecting rod 32 to rotate upward, and the on-off closes again, and the main circuit resumes power supply. After the main circuit resumes power supply, the fault classification module sends an instruction to the switch S3 again, and the switch S3 disconnects; when the contact handle 34 rotates upward, it drives the convex column 35 to leave the second trigger part, the elastic member 62 rebounds, the column body 61 leaves the contact below it, and the switch S2 disconnects, and the circuit of the relay mechanism 4 is disconnected to prevent the fault classification module from malfunctioning and sending a wrong instruction to close the switch S3, causing the circuit of the relay mechanism 4 to be always powered on and wasting electric energy. When it is necessary to replace the relay mechanism 4, hold the handle below the relay mechanism 4 and pull it downward. The convex strip 46 is squeezed and deformed and disengages from the arc-shaped groove 24. At the same time, the convex block 25 leaves the elastic piece 51, the elastic piece 51 rebounds, the bending piece 53 leaves the contact inside it, and the switch S1 disconnects to prevent misoperation from closing the circuit of the relay mechanism 4 and the electromagnet attracting foreign metal debris and affecting its normal use; under normal conditions, both the switch S1 and the switch S2 are in the off state, and the relay mechanism 4 is in an open circuit state.
