[0059] In one embodiment, referring to Figure 3 As shown, the support mechanism 2 includes a base plate 21, a support plate 22, a through-slot 23, an arcuate slot 24, and a protrusion 25. The support plates 22 are fixedly mounted at both ends of the base plate 21 and are fixedly connected to the switch body 1. The base plate 21 and the two support plates 22 enclose a gap for accommodating the relay mechanism 4. The through-slot 23 runs through the base plate 21, and the arcuate slots 24 are located on both sides of the through-slot 23. The protrusion 25 is located within the through-slot 23 and is fixedly connected to the base plate 21.

[0061] In one embodiment, referring to Figure 5 As shown, the rotation mechanism 3 includes a gate post 31, a connecting rod 32, a handle 33, a contact handle 34, and a protrusion 35. The gate post 31 is rotatably arranged between the support plates 22. One end of the connecting rod 32 is fixedly connected to the gate 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, and the protrusion 35 is fixedly connected to the contact handle 34. Preferably, the contact handle 34 is made of a permanent magnet, and the protrusion 35 is fixedly arranged below the contact handle 34. The outer edge of the gate post 31 is provided with a terminal. When the handle 33 is rotated upward, the terminal contacts the main circuit, forming a path for the main circuit. When the handle 33 is rotated downward, the terminal leaves the main circuit, disconnecting the main circuit.
[0062] The working principle of the circuit breaker opening and closing control gateway is as follows: install the opening and closing body 1 in the main circuit, push the handle 33, and make the connecting rod 32 drive the gate column 31 to rotate upward. When the handle 33 is turned to the top, the opening and closing body 1 is closed, and the main circuit is connected. Hold the handle under the relay mechanism 4, place the relay mechanism 4 under the support mechanism 2, and make the snap-fit assembly 43 face the inner slot below the support plate 22. At this time, the protective shell 44 faces the through slot 23, and the protrusion 25 faces the groove 45. Push the relay mechanism 4 upward, and the snap-fit assembly 43 enters the slot and the protective shell 44 enters the through slot 23. As the protective shell 44 moves upward, the protrusion 25 squeezes the first trigger part in the groove 45, causing the bent piece 53 to rotate inward around the top of the spring piece 51. When the protective shell 44 completely enters the through groove 23, the spring piece 51 rotates to the maximum displacement, and the bent piece 53 contacts the contact in the groove 45, and the switch S1 is closed at this time; when the protrusion 46 enters the through groove 23 and is squeezed and deformed, it enters the arc groove 24 along the through groove 23, and the pressure on the protrusion 46 becomes smaller, the protrusion 46 rebounds, and is stuck in the arc groove 24, fixing the relay mechanism 4 on the support mechanism 2; when a fault occurs in the main circuit, the switch is automatically disconnected, the handle 33 rotates downward, the contact handle 34 presses on the protective shell 44, and the boss 35 pushes the column 61 downward, the elastic member 62 contracts, and when the column 611 contacts the contact at the top of the shell 41, the switch S2 is closed; the fault classification module in the switch detects the fault type of the main circuit. If it is a short circuit caused by a transient fault such as lightning strike, bird contact with the wire, etc., after the fault is eliminated, the fault classification module sends a The switch S3 issues an instruction, the switch S3 is closed, the circuit of the relay mechanism 4 is connected, and the electromagnet in the protective shell 44 generates magnetism. At the moment the circuit of the relay mechanism 4 is connected, the instantaneous magnetism of the electromagnet is strong, and its magnetic pole is the same as the contact part of the contact handle 34, and the two generate a strong repulsive force, pushing the contact handle 34 upward, and the contact handle 34 drives the connecting rod 32 to rotate upward, the opening and closing switch is closed again, and the main circuit is restored to power. After the main circuit is restored to power, the fault classification module sends an instruction to the switch S3 again, and the switch S3 is disconnected; when the contact handle 34 rotates upward, it drives the boss 35 to leave the second trigger part, the elastic member 62 rebounds, and the column 61 leaves the contact below it, the switch S2 is disconnected, and the circuit of the relay mechanism 4 is disconnected, preventing the fault classification module from malfunctioning, issuing an erroneous instruction, closing the switch S3, and making the circuit of the relay mechanism 4 always energized, wasting electricity. When the relay mechanism 4 needs to be replaced, hold the handle below the relay mechanism 4 and pull it downward. The protrusion 46 is squeezed and deformed and comes out of the arc groove 24. At the same time, the protrusion 25 leaves the spring 51, the spring 51 rebounds, the bent piece 53 leaves the contact inside it, and the switch S1 is disconnected to prevent the circuit of the relay mechanism 4 from being closed due to misoperation. The electromagnet attracts external metal debris and affects its normal use. Under normal conditions, both switches S1 and S2 are in the disconnected state, and the relay mechanism 4 is in the open circuit state.
