[0046] The following is a further description of the specific implementation of the circuit breaker of the present utility model in conjunction with the embodiments given in the accompanying drawings. The circuit breaker of the present utility model is not limited to the description of the following embodiments.

[0047] like Figure 1-2 As shown, the circuit breaker of the utility model includes a housing 1 and a main circuit structure, and the main circuit structure includes an operating member 2 slidably arranged on the housing 1, and an operating mechanism 3, a contact system 4, an arc extinguishing system 6, and a control system 11, which are respectively arranged in the housing 1. The operating member 2 has an opening position and a closing position, and the operating member 2 switches between the opening position and the closing position by reciprocating sliding. The operating mechanism 3 includes an electromagnetic system 3-0, and the electromagnetic system 3-0 includes a magnetic component 3-0m and a top rod 3-05 movably inserted in the middle of the magnetic component 3-0m, and the top rod 3-05 has a first position and a second position and switches between the first position and the second position by reciprocating movement. The contact system 4 includes a moving contact mechanism 4-1 and a stationary contact 4-2 used in conjunction with each other. The moving contact mechanism 4-1 has a closed position and an open position. The moving contact mechanism 4-1 is closed with the stationary contact 4-2 when in the closed position (i.e., the contact system 4 is in the closed state), and is disconnected from the stationary contact 4-2 when in the open position (i.e., the contact system 4 is in the open state). One end of the top rod 3-05 is connected to the moving contact mechanism 4-1 by transmission. The top rod 3-05 switches between the first position and the second position to drive the moving contact mechanism 4-1 to switch between the closed position and the open position. The arc extinguishing system 6 is used in conjunction with the contact system 4 to extinguish the arc generated when the contact system 4 is closed and opened. The operating member 2 switches between the closing position and the opening position and drives the moving contact mechanism 4-1 to switch between the closing position and the opening position through the electromagnetic system 3-0, so that the contact system 4 switches between the closing state and the opening state, that is, the circuit breaker of the utility model switches between the closing state and the opening state. The electromagnetic system 3-0 works under the control of the control system 11 and drives the top rod 3-05 to switch between the first position and the second position, so that the top rod 3-05 drives the moving contact mechanism 4-1 to switch between the closing position and the opening position. Obviously, in the circuit breaker of the utility model, the closing position of the operating member 2, the first position of the top rod 3-05, the closing position of the moving contact mechanism 4-1, the closing state of the contact system 4, and the closing state of the circuit breaker correspond to each other, and the opening position of the operating member 2, the second position of the top rod 3-05, the opening position of the moving contact mechanism 4-1, the opening state of the contact system, and the opening state of the circuit breaker correspond to each other. Furthermore, both ends of the push rod 3-05 are respectively in transmission cooperation with the operating member 2 and the moving contact mechanism 4-1.

[0048] Specifically, Figure 1-2As shown, the two ends of the push rod 3-05 are respectively connected to the operating member 2 and the moving contact mechanism 4-1; one end of the operating member 2 is inserted into the shell 1 and the other end protrudes from the outside of the shell 1 for external force operation. The external force can be pressed and pulled by the operating member 2, thereby driving the contact system 4 to close and open (that is, driving the circuit breaker to close and open) through the operating mechanism 3.

[0049] Specifically, Figure 2-5 As shown, the moving contact mechanism 4-1 includes a contact support 4-10 and a moving contact 4-11 carried on the contact support 4-10. Further, the moving contact mechanism 4-1 is rotatably arranged by the contact support 4-10. Further, the moving contact mechanism 4-1 also includes a contact spring (not shown in the drawings of the specification); the contact support 4-1 is rotatably arranged on the housing 1 by the moving contact shaft 4-12, and the moving contact 4-11 and the contact support 4-10 are relatively rotatably arranged, so that after the moving contact 4-11 and the static contact 4-2 are closed, the contact support 4-10 can continue to rotate a certain angle relative to the moving contact 4-11, so that the contact spring applies a force to the moving contact 4-11 to press the static contact 4-2 to ensure reliable contact between the two.

[0050] As another embodiment, the movable contact mechanism 4 - 1 is arranged to move as a whole, and the movable contact mechanism 4 - 1 switches between a closed position and an open position by reciprocating movement to close and open with the stationary contact 4 - 2 .

[0051] Furthermore, the moving contact mechanism 4-1 is provided with two groups of moving contacts 4-11 arranged in parallel, which can effectively reduce the electric repulsion between the moving / static contacts and improve the current carrying capacity.

[0052] Furthermore, the operating mechanism 3 also includes a rear connecting rod 3-2, which is connected to one end of the top rod 3-05 of the electromagnetic system 3-0 and is hinged to the contact support 4-11. The axis of the hinge shaft between the rear connecting rod 3-2 and the contact support 4-11 is arranged parallel to the rotation axis of the moving contact mechanism 4-1 and spaced apart.

[0053] Specifically, the rear connecting rod 3-2 is provided with a rear connecting rod cavity 3-20 and a rear connecting rod socket 3-21, the rear connecting rod socket 3-21 is arranged on the side wall of the rear connecting rod cavity 3-20 (the side wall is close to the magnetic generating component 3-0m of the magnetic holding system 3-0), the rear rod body 3-0510 of the push rod 3-05 is inserted into the rear connecting rod socket 3-21 and the outer diameter of the rear rod body 3-0510 is adapted to the inner diameter of the rear connecting rod socket 3-21, the rear connecting cap 3-0511 of the push rod 3-05 is arranged in the rear connecting rod cavity 3-20 and the rear connecting rod The outer diameter of the connecting cap 3-0511 is larger than the inner diameter of the rear connecting rod socket 3-21 and the outer diameter of the rear rod body 3-0510; the rear connecting rod 3-2 includes a first rear connecting rod opening and a second rear connecting rod opening arranged on one side thereof, the first rear connecting rod opening is connected to the rear connecting rod cavity 3-20, the second rear connecting rod opening is connected to the rear connecting rod socket 3-21, the rear rod body 3-0510 enters the rear connecting rod socket 3-21 through the second rear connecting rod opening, and the rear connecting cap 3-0511 enters the rear connecting rod cavity 3-20 through the first rear connecting rod opening.

[0054] Specifically, the rear connecting rod 3-2 is hinged with the contact support 4-11 through the rear connecting shaft 3-32. Further, in the rear connecting rod 3-2 and the contact support 4-10, the connecting shaft 3-32 is set on one and moves synchronously with it, and the other is provided with a waist-shaped hole that matches the rear connecting shaft 3-32. Further, the rear connecting rod 3-2 is provided with a rear connecting rod connecting hole 3-22 for the rear connecting shaft 3-32 to be inserted and adapted thereto, the rear connecting shaft 3-32 is inserted into the rear connecting rod connecting hole 3-22 and moves synchronously with the rear connecting rod 3-2, and the contact support 4-11 is provided with a waist-shaped hole, which is a support connecting hole 4-100 for the rear connecting shaft 3-32 to be inserted.

[0055] As other embodiments, the push rod 3-05 may also be directly hinged to the contact support 4-11, and the detailed connection method between the two can be achieved through existing technologies and will not be described in detail here.

[0056] Furthermore, the main circuit structure also includes a sampling device 7 coupled with the contact system 4 (that is, coupled with the moving contact mechanism 4-1), and the sampling device 7 is used to collect the current signal flowing through the contact system 4 and is connected to the control system 11; when an overload and / or short-circuit current flows through the contact system 4 (that is, the control system 11 detects the overload and / or short-circuit current through the sampling device 7), the control system 11 controls the electromagnetic system 3-0 to work and drives the top rod 3-05 to move from the first position to the second position, thereby driving the moving contact mechanism 4-1 to move from the closed position to the open position. In the circuit breaker of the utility model, the electromagnetic system 3-0 serves as both a power mechanism for driving the contact system 4 to close and open, and a mechanism for realizing overload and / or short-circuit protection. Compared with the existing circuit breakers, the bimetallic element for realizing overload protection and / or the electromagnetic tripping mechanism for realizing short-circuit protection can be eliminated, which is beneficial to reducing the number of components of the circuit breaker, simplifying the structure of the circuit breaker, and providing more space for the layout of various components of the circuit breaker, thereby helping to reduce the overall size of the circuit breaker. In the circuit breaker of the utility model, when overload and short-circuit currents flow through the contact system 4, the control system 11 controls the electromagnetic system 3-0 to work and drives the top rod 3-05 to move from the first position to the second position; that is, the electromagnetic system 3-0 serves as a mechanism for overload protection and short-circuit protection at the same time.

[0057] Specifically, the sampling device 7 is a manganese copper shunt connected in series with the contact system 4 (that is, connected in series with the moving contact mechanism 4-1); or, the sampling device 7 is a mutual inductor coupled with the contact system 4 (that is, coupled with the moving contact mechanism 4-1), for example, the mutual inductor can be coupled with the contact system 4 by being sleeved on a conductor connected in series with the contact system 4. In the circuit breaker of the utility model, the sampling device 7 preferably adopts a manganese copper shunt.

[0058] Furthermore, the main circuit structure further includes a first terminal 8-0 and a third terminal 5-0, and the first terminal 8-0, the contact system 4 and the third terminal 5-0 are connected in series in sequence.

[0060] Furthermore, the main circuit structure also includes a connecting conductor 20, and the static contact 4-2 is electrically connected to the third terminal 5-0 via the connecting conductor 20.

[0061] Furthermore, the main circuit structure also includes a signal terminal 12 connected to the control system 11, and the control system 11 communicates with external equipment through the signal terminal 12. For example, the control system 11 transmits data through the signal terminal 12 and receives external control signals (remote closing signal and remote opening signal) through the signal terminal 12.

[0062] Furthermore, the circuit breaker of the utility model also includes a secondary circuit structure 9 arranged in the housing 1, and the secondary circuit structure 9 is a straight-through circuit. The so-called "straight-through circuit" refers to a circuit structure in which there is no operable breakpoint in the circuit (for example, there is no breakpoint realized by the moving contact and the static contact, the breakpoint is closed when the moving contact and the static contact are closed, and the breakpoint is disconnected when the moving contact and the static contact are disconnected) and it can be directly connected to the external circuit. Further, the secondary circuit structure 9 includes a second terminal 8-1, a straight-through conductor and a fourth terminal 5-1 connected in series in sequence. Further, the straight-through conductor is a conductive plate or a soft conductor. It should be pointed out that the circuit breaker of the utility model can only be provided with a main circuit structure, and the circuit breaker is a single-phase circuit breaker (that is, a 1P type circuit breaker); the circuit breaker of the utility model can also be provided with a main circuit structure and a secondary circuit structure at the same time, and the circuit breaker is a two-phase circuit breaker (that is, a 1P+1N type circuit breaker). In addition, multiple circuit breakers of this embodiment can be arranged side by side, and the operating parts and operating system of the circuit breaker can cooperate with each other to realize a two-phase (2P type circuit breaker) or multi-phase (3P or 4P) circuit breaker.

[0063] Specifically, the second terminal 8 - 1 is an incoming terminal of the secondary loop structure 9 , and the fourth terminal 5 - 1 is an outgoing terminal of the secondary loop structure 9 .

[0064] like Figure 2 As shown, the control system 11 includes a circuit board 11p.

[0065] Furthermore, the control system 11 also includes a first sampling terminal 11-0 connected to the circuit board 11p, and the first sampling terminal 11-0 is electrically connected to the connecting conductor 20 to detect the voltage signal, current signal and on / off state of the main circuit structure, so as to determine the current state of the circuit breaker of the utility model.

Furthermore, the yoke 3-03 is a square frame structure, and the first static iron core and the second static iron core are formed by a pair of side walls of the yoke 3-03. Furthermore, the yoke 3-03 includes a yoke seat and a yoke end plate of a U-shaped structure, the open end of the U-shaped structure of the yoke seat is connected to the yoke end plate, and the yoke end plate and the bottom plate of the U-shaped structure of the yoke seat, one as the first static iron core and the other as the second static iron core.

[0069] It should be pointed out that the electromagnetic system 3-0 can also adopt other structural types of existing magnetic holding systems. For example, the difference between an existing magnetic holding system and this embodiment is that it includes two groups of permanent magnets, and the two groups of permanent magnets are respectively arranged on the outside of the axial ends of the coil assembly 3-01, and the electromagnetic coil of the coil assembly 3-01 is located between the two groups of permanent magnets.

[0070] Furthermore, the push rod 3-05 includes a front push rod 3-050 and a rear push rod 3-051, one end of the front push rod 3-050 is inserted in the moving iron core 3-02 and the other end protrudes outside the axial end of the electromagnetic coil and is connected to the operating member 2, and one end of the rear push rod 3-051 is inserted in the moving iron core 3-02 and the other end protrudes outside the axial end of the electromagnetic coil and is connected to the moving contact mechanism 4-1.

[0071] Specifically, the front push rod 3-05 includes a front rod body 3-0500 and a front connecting cap 3-0501, one end of the front rod body 3-0500 is connected to the front connecting cap 3-0501 and the other end is connected to the moving iron core 3-02 (for example, one axial end of the moving iron core 3-02 is inserted into the moving iron core 3-02); the rear push rod 3-051 includes a rear rod body 3-0510 and a rear connecting cap 3-0511, one end of the rear rod body 3-0510 is connected to the rear connecting cap 3-0511 and the other end is connected to the moving iron core 3-02 (for example, the other axial end of the moving iron core 3-02 is inserted into the moving iron core 3-02). Furthermore, the front rod body 3-0500 and the front connecting cap 3-0501 are an integrated structure or a detachable split structure; the rear rod body 3-0510 and the rear connecting cap 3-0511 are an integrated structure or a detachable split structure.

[0072] like Figure 2 As shown, the circuit breaker of the utility model also includes a first locking member 14 and a first locking member reset spring 16 slidably arranged in the housing 1. The sliding direction of the first locking member 14 is perpendicular to the moving direction of the operating member 2. The first locking member reset spring 16 acts on the first locking member 14 to make it have a tendency to move to the outside of the housing 1 and make the first locking protrusion 14-1 of the first locking member 14 protrude outside the housing 1. The first locking member 14 moves toward the inside of the housing 1 when the first locking protrusion 14-1 is squeezed by an external force (that is, when the first locking protrusion 14-1 is squeezed by an external force, the first locking member 14 is driven to move toward the inside of the housing 1 as a whole); when the circuit breaker is in the open state, the first locking member 14 is driven by the pulled operating member 2 to move toward the inside of the housing 1, that is, when the circuit breaker is in the open state, the operating member 2 is pulled in the open position to drive the first locking member 14 to move toward the inside of the housing 1.

[0073] When the circuit breaker of the utility model is installed in a circuit breaker installation cabinet (such as a distribution cabinet, a control cabinet or other electrical cabinet) in actual use, the first locking protrusion 14-1 is squeezed by the structure of the circuit breaker installation cabinet and moves toward the inside of the housing 1, which will not affect the installation of the circuit breaker into the designated position of the circuit breaker installation cabinet. After the circuit breaker is installed in the designated position and in place, the first locking protrusion 14-1 will be opposite to the first locking hole set at the designated position of the circuit breaker installation cabinet and move to the outside of the housing 1 and insert into the first locking hole, thereby cooperating with the limit position of the circuit breaker installation cabinet, so that the circuit breaker will not be pulled out of the designated position of the circuit breaker installation cabinet in the closed state, which not only ensures the personal safety of the operator, but also ensures the reliability and stability of electricity use.

[0074] The circuit breaker of the utility model further comprises a second locking member (not shown in the figure) rotatably arranged in the housing 1, and the second locking member comprises a second locking protrusion; when the operating member 2 moves from the opening position to the closing position, the second locking member is directly or indirectly driven by the operating member 2 to rotate forwardly so that the second locking protrusion moves toward the outside of the housing 1; when the operating member 2 moves from the closing position to the opening position, the second locking member rotates reversely so that the second locking protrusion moves toward the inside of the housing 1; when the operating member 2 is in the closing position, the operating member 2 directly or indirectly restricts the second locking member from rotating reversely.

[0075] The second locking member is driven by the operating member 2 to rotate forward when the operating member 2 moves from the opening position to the closing position, so that the second locking protrusion moves toward the outside of the housing 1. The second locking protrusion is used to cooperate with the structural limit of the circuit breaker installation cabinet (such as a distribution cabinet, a control cabinet or other electrical cabinet), thereby preventing the circuit breaker of the utility model from being installed in the circuit breaker installation cabinet in the closed state, thereby ensuring the personal safety of the operator; after the circuit breaker of the utility model is installed in the circuit breaker installation cabinet in the opening state and installed in place, the second locking protrusion protruding from the outside of the housing 1 is also used to be opposite to the second locking hole of the circuit breaker installation cabinet and extend into it, and the second locking protrusion Cooperating with the structural limit of the circuit breaker installation cabinet, when the operating member 2 is in the closing position, the operating member 2 directly or indirectly cooperates with the second locking member to prevent it from rotating in the opposite direction, thereby preventing the circuit breaker of the utility model from being pulled out of the circuit breaker installation cabinet in the closing state, which not only ensures the personal safety of the operator, but also ensures the stability and reliability of electricity use; when the operating member 2 moves from the closing position to the opening position, the second locking member rotates in the opposite direction to move the second locking protrusion toward the inside of the housing 1, and the second locking protrusion withdraws from the second locking hole, thereby releasing the limit cooperation with the circuit breaker installation cabinet, and the second locking member will not affect the removal of the circuit breaker of the utility model from the circuit breaker installation cabinet.

[0076] Furthermore, the second locking protrusion is a square protrusion, so as to avoid the situation where the second locking protrusion is squeezed and the second locking member is damaged or deformed when the operating member 2 is in the closing position, and the circuit breaker of the utility model is directly installed in the circuit breaker installation cabinet.

[0077] Furthermore, when the operating member 2 moves from the closing position to the opening position, the second locking member is directly or indirectly driven by the operating member 2 to rotate in the reverse direction so that the second locking protrusion moves toward the inside of the housing 1. Furthermore, the second locking member is driven to rotate in the reverse direction by the operating member 2 pulled out at the opening position, and the first locking member 14 is driven to move toward the inside of the housing 1 by the reversely rotating second locking member when the operating member 2 at the opening position is pulled out; that is, when the operating member 2 is pulled out at the opening position, the operating member 2 simultaneously drives the second locking member to rotate in the reverse direction, and the second locking member simultaneously drives the first locking member 14 to move toward the inside of the housing 1.

[0078] As another embodiment, the circuit breaker of the utility model includes a second locking member reset spring acting on the second locking member to make it have a tendency to rotate in the reverse direction. When the operating member 2 moves from the closing position to the opening position, the operating member 2 no longer restricts the second locking member from rotating in the reverse direction, and the second locking member reset spring drives the second locking member to rotate in the reverse direction.

[0079] The circuit breaker of the present invention may be provided with both the first locking member 14 and the second locking member, or may be provided with only the first locking member 14 or the second locking member.

[0080] like Figure 3-4 As shown, the circuit breaker of the utility model further includes an indicator 13 having a first indication position and a second indication position arranged in the middle of the operating member 2, and the operating member 2 includes an indication hole 2-1 used in conjunction with the indicator 13; when the operating member 2 moves to the closing position, the indicator 13 is driven by the indicator driving structure to rotate to the first indication position; when the operating member 2 moves to the opening position, the indicator 13 is driven by the indicator driving structure to rotate to the second indication position; that is, the first indication position and the second indication position of the indicator 13 correspond to the closing position and the opening position of the operating member 2 respectively and correspond to the closing state and the opening state of the circuit breaker of the utility model respectively. The indicator 13 is arranged in the middle of the operating member 2, which is conducive to improving the structural compactness of the circuit breaker and reducing the installation space required for the circuit breaker as a whole.

[0081] Further, the indicator 13 includes an indicator portion 13-0, an indicator connecting portion 13-1 and an indicator mounting portion 13-2 which are connected in sequence, and a closing actuated portion 13-30 and an opening actuated portion 13-31 which are arranged on the indicator mounting portion 13-2; the indicator 13-0 is used in conjunction with the indicator hole 2-1 of the operating member 2, the indicator 13 is rotatably mounted on the operating member 2 through the indicator mounting portion 13-2, and the closing actuated portion 13-30 and the opening actuated portion 13-31 are arranged along the indicator mounting portion 13-2. The rotation direction is arranged in sequence; the indicator driving structure is realized by the housing 1 (for example, a driving protrusion is arranged on the housing 1, and the driving protrusion is inserted between the closing actuated part 13-30 and the opening actuated part 13-31); when the operating member 2 moves to the closing position, the closing actuated part 13-0 is pressed by the indicator driving structure to rotate the indicator 13 to the first indicating position; when the operating member 2 moves to the opening position, the opening actuated part 13-1 is pressed by the low pressure of the indicator driving structure to rotate the indicator 13 to the second indicating position.

[0082] As other embodiments, the indicator 13 is not provided with a closing actuated portion 13-30 and an opening actuated portion 13-31, but only one indicator actuated portion is provided on the indicator mounting portion 13-2; accordingly, the indicator driving structure includes two indicator driving protrusions, one is a closing driving protrusion and the other is an opening driving protrusion, and the indicator actuated portion is inserted between the two indicator driving protrusions; when the operating member 2 moves to the closing position, the closing driving protrusion presses the indicator actuated portion to rotate the indicator 13 to the first indicating position; when the operating member 2 moves to the opening position, the opening driving protrusion presses the indicator actuated portion to rotate the indicator 13 to the second indicating position.

[0083] like Figure 1 As shown, the housing 1 also includes an operating member mounting hole 1-6 for inserting the operating member 2 therein, a first socket 1-20 cooperating with the first terminal 8-0, a second socket 1-21 cooperating with the second terminal 8-1, a signal socket 1-3 cooperating with the signal terminal 12, a third socket 1-50 cooperating with the third terminal 5-0, and a fourth socket 1-51 cooperating with the fourth terminal 5-1.

[0084] like Figure 1 As shown, the housing 1 further includes a signal window 1-4, and the circuit breaker further includes an indicating element connected to the control system 11, and the indicating element cooperates with the signal window 1-4 to indicate the state of the circuit breaker, such as the closing and opening state, fault state, communication state, etc. of the circuit breaker; the signal window 1-4 and the operating element mounting hole 1-6 are arranged on the same side wall of the housing 1. Further, the indicating element is an indicator light.

Further, the first opening and the second opening are the same opening.

[0086] like Figure 1 As shown, the housing 1 also includes an installation guide structure 1-1, which is used to cooperate with the guide structure on the circuit breaker installation cabinet when the circuit breaker of the utility model is installed in the circuit breaker installation cabinet (such as a distribution cabinet, a control cabinet or other electrical cabinet), so that the circuit breaker of the utility model can be installed in place with a correct posture. Further, the installation guide structure 1-1 is a guide rib structure.
