[0002] Low-voltage circuit breakers, also known as automatic air switches or automatic air circuit breakers, are electrical appliances that have both manual switch functions and automatic protection against loss of pressure, undervoltage, overload, and short circuit. They can be used to distribute electrical energy, protect power lines and power terminals, and automatically cut off the circuit when they are seriously overloaded or have short circuits or undervoltage faults. However, traditional low-voltage circuit breakers have poor application flexibility and cannot flexibly set and change the rated current values ​​of each branch circuit. They have poor versatility for both home and commercial use. With the progress and development of society, the development and application of the digitalization process of power system control methods has put higher and higher requirements on system visualization, automation, networking, real-time, and precision. The application of intelligent technology has become the mainstream trend in the development of low-voltage circuit breakers.

[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0028] A neutral pole and protection pole structure of an intelligent power distribution circuit breaker includes:

[0029] Reference Figure 1-Figure 5The neutral pole and protection pole structure of the intelligent distribution circuit breaker includes a circuit breaker body 22, wherein the circuit breaker body 22 includes a neutral pole mechanism 1 and multiple protection pole mechanisms 2, and the tops of the neutral pole mechanism 1 and the protection pole mechanism 2 are both provided with a toggle switch 8, and the toggle switches 8 of the multiple protection pole mechanisms 2 are connected, and adjustment chambers 9 are provided on both sides of the circuit breaker body 22, and a rotary motor 10 is provided inside the adjustment chamber 9, and a transmission assembly is provided at the driving end of the rotary motor 10, and the output end of the transmission assembly is connected to the side of the corresponding toggle switch 8, and a communication module 11 and a control processor 12 are provided in the adjustment chamber 9, and the control processor 12 is electrically connected to the communication module 11 and the rotary motor 10.

[0030] The present invention, through the set rotating motor 10, transmission assembly and communication module 11, when in use, can use the rotating motor 10 through the control terminal in conjunction with the communication module 11 to remotely control the opening and closing of the circuit breaker of the device, and because multiple switches of the protection poles are connected, it can be ensured that except for the neutral pole that can be opened and closed, even if only one protection pole is overloaded, all poles can basically be connected or disconnected at the same time, and after disconnection, the circuit breaker can be remotely controlled to be connected again through the control terminal, without the need for manual presence, which is very convenient.

[0031] In this embodiment, the toggle switch 8 of the neutral pole mechanism 1 and the toggle switch 8 of the adjacent protective pole mechanism 2 are connected through a flexible sleeve 13, and the flexible sleeve 13 is made of insulating material. When the toggle switch 8 of the protective pole mechanism 2 is toggled, after moving to a certain extent, it can drive the neutral pole mechanism 1 to move, and when the neutral pole mechanism 1 moves, the toggle switch 8 of the protective pole mechanism 2 can be driven to toggle through the flexible sleeve 13, so that the neutral pole can be closed before the protective pole and opened later.

[0032] In this embodiment, the transmission assembly includes a worm 14, a worm wheel 15, a first gear 16 and a second gear 17. The worm 14 is installed at the driving end of the rotary motor 10, the worm wheel 15 is meshed with the worm 14, the worm wheel 15 is installed at the center of the first gear 16, the second gear 17 is meshed with the first gear 16, the second gear 17 is connected to the side of the corresponding toggle switch 8, the first gear 16 and the second gear 17 are both rotatably installed in the adjustment chamber 9 through a rotating shaft, the rotary motor 10 rotates the worm 14 to drive the worm wheel 15, the worm wheel 15 drives the first gear 16 to rotate, and the first gear 16 drives the second gear 17 to rotate, thereby realizing the toggle switch 8.

[0033] In this embodiment, a telescopic motor 18 is installed on the second gear 17, and some of the toggle switches 8 are tubular. Push rods 21 are movably arranged inside some of the toggle switches 8. The push rods 21 are connected to each other by elastic connecting belts 19. The driving end of the telescopic motor 18 is connected to the corresponding push rods 21. The telescopic motor 18 can push the push rods 21 to adjust the positions of some push rods 21 in the corresponding toggle switches 8. When the push rods 21 are completely in the toggle switches 8, there is no restriction between the toggle switches 8 and they can move relative to each other. In this way, a single opening and closing operation of a certain pole can be performed. When one push rod 21 enters two toggle switches 8 at the same time, the two toggle switches 8 can move at the same time.

[0034] In this embodiment, the interior of the neutral pole mechanism 1 and the protection pole mechanism 2 both include:

[0035] An access area having access terminals;

[0036] An outlet area having outlet terminals;

[0037] A tripping zone having a tripping assembly;

[0039] In this embodiment, a current transformer 20 is further provided in the regulating chamber 9, and the access terminal 4 has a detection line that penetrates into the current transformer 20, which is used to analyze the current information of the access circuit and transmit the data to the control terminal.

[0040] In this embodiment, the tripping assembly is an electromagnetic tripping structure, including a static contact, a moving contact, a locking assembly, a handle and an electromagnetic driving mechanism. When the static contact contacts the moving contact, the locking assembly locks and keeps the moving contact fixed; when a short circuit occurs in the connected circuit, the electromagnetic driving mechanism pushes the locking assembly to unlock and cause the moving contact to trip.

[0041] Figure 3 It can be seen that the overall structural layout of the circuit breaker assembly is the same as that of the prior art, with input terminals and output terminals on both sides, and the housing is provided with an input area and an output area. Both the input terminal and the output terminal include a pressing piece that moves up and down by bolts, and the pressing piece corresponds to a fixed bridge plate. Both the input area and the output area are provided with openings for easy access to external circuits. After the contacts of the external circuit are inserted into the corresponding openings, the pressing piece is moved to make them close to the bridge plate.

[0042] The bridge plate is connected to the arc extinguishing assembly through an arc striking plate. When an arc occurs inside the circuit breaker, the arc can be introduced into the arc extinguishing assembly through the arc striking plate to extinguish the arc.

[0043] The arc extinguishing assembly is a structure in which multiple metal sheets are stacked and arranged at equal distances, which is the same as the existing arc extinguishing mechanism, and its principle is not repeated here.

[0044] The upper part of the arc extinguishing assembly is the electromagnetic driving mechanism, and the upper part of the electromagnetic driving mechanism is the locking assembly and the handle.
