Description

Technical Field

[0001] This invention relates to the field of switching electrical equipment technology, and in particular to a hybrid switch and circuit breaker for realizing the opening and closing of a circuit breaker. Background Technology

[0002] A circuit breaker is a common electrical protection device that provides short-circuit and overload protection. It can quickly interrupt the fault current when an overload or short-circuit fault occurs in the power distribution system, thus protecting the power distribution system and electrical equipment.

[0003] With the continuous development and innovation of circuit breaker technology, a hybrid switch combining electronic and mechanical components has emerged. This hybrid switch comprises a fast mechanical switch, a fully controlled solid-state switch module, a thyristor module, and a surge arrester. The fast mechanical switch and the fully controlled solid-state switch module are connected in series and then connected in parallel with the thyristor module and surge arrester, respectively. Through the combination of the fast mechanical switch, the fully controlled solid-state switch, and the thyristor, reliable interruption of fault current is achieved. The fast mechanical switch, after its inherent opening delay, always opens under zero-current and low-voltage conditions. Although the structural design of this hybrid switch can reduce the erosion of the moving and stationary contacts by electric arc, it still relies solely on the time difference to assume the order of breaking, and cannot guarantee arc-free breaking. Arc generation still occurs. Furthermore, during the installation of the circuit breaker in the cabinet, if the busbar in the cabinet is energized, a small electric arc will be generated between the circuit breaker terminals and the busbar when the circuit breaker is in the closed state, which can easily cause a safety accident.

[0054] Example

[0055] like Figure 1 and Figure 2 As shown, an embodiment of the present invention provides a hybrid switch 100 for realizing the opening and closing of a circuit breaker 1000, mainly used to realize the closing and opening of the solid-state circuit breaker 1000. The hybrid switch 100 includes an electronic switch 20, a solid-state circuit switch 30 connected in series in the circuit relationship, and a mechanical switch 10.

[0056] The mechanical switch 10 comprises at least one operating member 13, a static contact 11 fixed relative to a housing 200 of the circuit breaker 1000, and a dynamic contact 12 connected with the operating member 13. The dynamic contact 12 is arranged opposite to the static contact 11, so that the static contact 11 is located in a movement track of the dynamic contact 12, and the dynamic contact 12 and the static contact 11 are engaged or separated. The operating member 13 is movably arranged on the housing 200, and a trigger 131 is arranged on the operating member 13. The trigger 131 can trigger the electronic switch 20 to turn on or off the solid-state circuit switch 30. Figure 3 and Figure 4 Specifically, the operating member 13 is driven to move in a first direction by a first preset distance, and the dynamic contact 12 is engaged with the static contact 11. The operating member 13 is continuously driven to move in the first direction by a second preset distance, and the trigger 131 is moved to a preset position to trigger the electronic switch 20 to turn on the solid-state circuit switch 30, so as to realize closing of the circuit breaker 1000.

[0057] Please refer to Figure 5 and Figure 6 The operating member 13 is driven to move in a second direction by the second preset distance, and the trigger 131 is moved away from the electronic switch 20 to turn off the solid-state circuit switch 30. At this time, the circuit breaker 1000 is opened, and the operating member 13 is continuously driven to move in the second direction by the first preset distance, and the dynamic contact 12 is separated from the static contact 11. The second direction is opposite to the first direction.

[0058] It should be noted that, for example, the first direction is that the operating member 13 moves from left to right, and the second direction is that the operating member 13 moves from right to left. The first preset distance and the second preset distance can be designed according to actual needs, and in this embodiment, are not specifically limited.

[0059] The hybrid switch 100 provided by the embodiment of the present application is used to realize opening and closing of the circuit breaker 1000. During use, when the circuit breaker 1000 is closed, the operating member 13 is driven to move in a first direction by a first preset distance, and the dynamic contact 12 is engaged with the static contact 11. At this time, the electronic switch 20 is still in an off state, the operating member 13 is continuously driven to move in the first direction by a second preset distance, the trigger 131 is moved to a preset position to trigger the electronic switch 20 to turn on the solid-state circuit switch 30, and the circuit breaker 1000 is closed. That is, the mechanical switch 10 is first closed to turn on, the electronic switch 20 is then turned on to turn on the solid-state circuit switch 30, and finally the circuit breaker 1000 is closed. In this way, the mechanical switch 10 is opened in a zero-voltage and zero-current state, and arc generation at the dynamic contact 12 and the static contact 11 caused by simultaneous turn-on of the mechanical switch 10 and the electronic switch 20 is avoided.

[0060] When the circuit breaker 1000 is tripped, the driving operation member 13 moves in a second direction opposite to the first direction by a second preset distance, the trigger member 131 moves away from the electronic switch 20 to turn off the solid-state circuit switch 30, so as to realize tripping of the circuit breaker 1000; the driving operation member 13 continues to move in the second direction by a first preset distance, the movable contact 12 is separated from the fixed contact 11, so that when the circuit breaker 1000 is tripped, the electronic switch 20 is turned off earlier than the mechanical switch 10, so that the mechanical switch 10 is in a zero-voltage and zero-current state when it is tripped off, thereby the generation of arc can be well avoided.

[0061] In the embodiment, through the position relationship between the trigger member 131 and the electronic switch 20 and the movement trajectory of the operation member 13, the mechanical switch 10 is triggered by the trigger member 131 to turn on the solid-state circuit switch 30 after a delay after the mechanical switch 10 is closed, the delay is realized by the movement trajectory of the operation member 13, rather than by a time delay, so that the electronic switch 20 is turned off by the trigger member 131 after being triggered, so that the mechanical switch 10 is in a power-off state when it is closed after the solid-state circuit switch 30, that is, the mechanical switch 10 is in a power-off state when it is closed after the solid-state circuit switch 30, which ensures that the true arcless breaking is realized, thereby the service life of the circuit breaker 1000 is increased, and the safety in use is ensured.

[0062] As shown in FIGS. Figure 1 and Figure 3 In some embodiments of the present application, the operation member 13 optionally comprises a pulling button 132 and a linkage mechanism 133.

[0063] Specifically, the pulling button 132 is slidingly arranged in the housing 200 of the circuit breaker 1000 in the first direction and the second direction, so that the pulling button 132 reciprocally slides in the first direction and the second direction relative to the housing 200.

[0064] The linkage mechanism 133 is rotationally arranged in the housing 200, one end of the linkage mechanism 133 is connected with the pull button 132, and the other end is connected with the movable contact 12. In this way, when the pull button 132 slides in the first direction by a first preset distance, the linkage mechanism 133 rotates and drives the movable contact 12 to rotate, so that the movable contact 12 is combined with the static contact 11. When continuing to slide in the first direction by a second preset distance, the linkage mechanism 133 continues to rotate, at this time, the trigger 131 reaches the preset position, and triggers the electronic switch 20 at the preset position, so that the circuit of the electronic switch 20 is turned on. When the pull button 132 slides in the second direction by the second preset distance, the trigger 131 leaves the preset position, and triggers the electronic switch 20 to be turned off. At this time, the movable contact 12 and the static contact 11 are still in the combined state, and when continuing to move in the second direction by the first preset distance, the movable contact 12 is separated from the static contact 11, and the mechanical switch 10 is turned off.

[0065] In the embodiment, the trigger 131 can be arranged on the pull button 132, and the electronic switch 20 is located in the movement track of the trigger 131, so that the trigger 131 can trigger the on-off of the electronic switch 20. Of course, the trigger 131 can also be arranged on the linkage mechanism 133, at this time, the electronic switch 20 is still located in the movement track of the trigger 131, so as to be triggered by the trigger 131.

[0066] Further, the linkage mechanism 133 includes a rotating structure 1331 and a first connecting rod 1332.

[0067] The rotating structure 1331 is rotationally arranged on the housing 200 and connected with the movable contact 12, one end of the first connecting rod 1332 is connected with the pull button 132, and the other end is connected with the rotating structure 1331.

[0068] Specifically, when the pull button 132 slides in the first direction by the first preset distance, the first connecting rod 1332 drives the rotating structure 1331 to rotate clockwise and drives the movable contact 12 to rotate, so that the movable contact 12 is combined with the static contact 11. When continuing to slide in the first direction by the second preset distance, the first connecting rod 1332 drives the rotating structure 1331 to continue to rotate, at this time, the trigger 131 reaches the preset position, and triggers the electronic switch 20 at the preset position, so that the circuit of the electronic switch 20 is turned on. When the pull button 132 slides in the second direction by the second preset distance, the trigger 131 leaves the preset position, and triggers the electronic switch 20 to be turned off. At this time, the movable contact 12 and the static contact 11 are still in the combined state, and when continuing to move in the second direction by the first preset distance, the first connecting rod 1332 drives the rotating structure 1331 to rotate counterclockwise to separate the movable contact 12 from the static contact 11, and the mechanical switch 10 is turned off.

[0069] Optionally, the trigger 131 is arranged on the pull button 132, and the electronic switch 20 is located in the movement track of the trigger 131, so that the trigger 131 can trigger the on-off of the electronic switch 20. Of course, the trigger 131 can also be arranged on the rotating structure 1331, and the electronic switch 20 is still located in the movement track of the trigger 131, so as to be triggered by the trigger 131.

[0070] In the embodiment, the first connecting rod 1332 and the rotating structure 1331 are arranged, the movement structure is simple, and the operation is convenient.

[0071] As shown in Figure 3 Further, the rotating structure 1331 comprises a rotating plate 13311, a contact support 13312 and a second connecting rod 13313.

[0072] The rotating plate 13311 is rotationally arranged on the shell 200 and connected with the first connecting rod 1332. Specifically, the rotating plate 13311 is rotationally connected with the shell 200 through a rotating shaft. The first connecting rod and the second connecting rod are both U-shaped rods, the rotating plate 13311 is provided with a first connecting hole and a second connecting hole matched with the first connecting rod 1332 and the second connecting rod 13313 respectively, one end of the first connecting rod 1332 is connected with the pull button 132, and the other end is inserted into the first connecting hole.

[0073] One end of the second connecting rod 13313 is inserted into the second connecting hole, so that the second connecting rod 13313 is connected with the rotating plate 13311, and the other end is connected with the contact support 13312. The contact support 13312 is arranged in the first direction and rotationally arranged on the shell 200, and the contact support 13312 is rotationally connected with the shell 200 through a pin shaft. The movable contact 12 is arranged on the contact support 13312.

[0074] As shown in Figure 3 and Figure 4 As shown in the first direction from left to right and the second direction from right to left, the trigger 131 is arranged on the pull button 132, for example, the pull button 132 is slid to the right by a first preset distance, the first connecting rod 1332 drives the rotating plate 13311 to rotate clockwise and drives the contact 12 support to rotate, the movable contact 12 rotates with the contact support 13312, so that the movable contact 12 is combined with the static contact 11, when the pull button 132 is continuously pushed to slide to the right by a second preset distance, the first connecting rod 1332 drives the rotating plate 13311 to continue to rotate clockwise, at this time, the trigger 131 reaches the preset position, and triggers the electronic switch 20 at the preset position, so that the circuit of the electronic switch 20 is conducted.

[0075] Of course, in other embodiments, the trigger 131 can also be arranged on the rotating plate 13311, and the electronic switch 20 is arranged below the rotating plate 13311, so that the trigger 131 triggers the electronic switch 20.

[0076] In the embodiment, the first connecting rod 1332, the rotating plate 13311, the second connecting rod 13313 and the contact bracket 13312 are arranged, so that the linkage mechanism 133 occupies less space for the long solid-state circuit breaker 1000.

[0077] It should be understood that the linkage mechanism 133 can also adopt other linkage structures in the mechanical switch of the circuit breaker, and is not limited to the linkage mechanism 133 in the embodiment.

[0078] As shown in FIG. 1 and FIG. 2, the linkage mechanism 133 includes a first connecting rod 1332, a rotating plate 13311, a second connecting rod 13313 and a contact bracket 13312. Figure 1 and Figure 2 As shown in FIG. 1 and FIG. 2, the linkage mechanism 133 includes a first connecting rod 1332, a rotating plate 13311, a second connecting rod 13313 and a contact bracket 13312.

[0079] In the embodiment, the length of the strip-shaped slot 1321 along the first direction or the second direction is equal to the second preset distance. In this way, the trigger 131 can be triggered to move away from the preset position by moving the pull button 132 to the left by a distance equal to the length of the strip-shaped slot 1321, so as to trigger the electronic switch 20 to be turned off.

[0080] As shown in FIG. 1 and FIG. 2, the linkage mechanism 133 includes a first connecting rod 1332, a rotating plate 13311, a second connecting rod 13313 and a contact bracket 13312. Figure 7In some embodiments of the present application, the operation member 13 can be a pulling button 132, and the trigger member 131 is a pulling rod 1311. The pulling rod 1311 is connected to the pulling button 132, and the pulling rod 1311 is arranged in the housing 200 of the circuit breaker 1000. In other embodiments of the present application, for the scheme of the pulling button 132, other schemes can also be selected, such as the operation member 13 including a rotating button 134 and a linkage assembly 135. The rotating button 134 is arranged to rotate in the housing 200 of the circuit breaker 1000. The linkage assembly 135 is arranged in the housing 200. One end of the linkage assembly 135 is connected to the rotating button 134, and the other end is connected to the movable contact 12. The trigger member 131 is arranged on the rotating button 134.

[0081] In the present embodiment, the rotating button 134 is rotated in the counterclockwise direction by a first preset distance. The rotating button 134 is continuously rotated in the counterclockwise direction by a second preset distance. The trigger member 131 moves to a preset position to trigger the electronic switch 20 to turn on the solid-state circuit switch 30, so as to realize the closing of the circuit breaker 1000. Conversely, the rotating button 134 is rotated in the clockwise direction by the second preset distance. The trigger member 131 moves away from the electronic switch 20 to turn off the solid-state circuit switch 30, so as to realize the opening of the circuit breaker 1000. The rotating button 134 is continuously rotated in the clockwise direction by the first preset distance. The movable contact 12 is separated from the static contact 11, so as to ensure that the mechanical switch 10 is in a zero-voltage and zero-current state when it is separated.

[0082] In addition, it should be noted that the linkage assembly 135 includes a contact bracket 13312 and a second connecting rod 13313. One end of the second connecting rod 13313 is connected to the rotating button 134, and the other end is connected to the contact bracket 13312. The movable contact 12 is arranged on the contact bracket 13312. Of course, in other embodiments, the linkage assembly 135 can also adopt other linkage structures in the mechanical switch of the circuit breaker.

[0083] In some embodiments of the present application, the electronic switch 20 can be a micro switch. When the trigger member 131 moves to the preset position, the trigger member 131 abuts against the action spring of the micro switch, so as to make the micro switch turn on, thereby realizing the closing of the circuit breaker 1000. In addition, when the trigger member 131 moves away from the preset position, the trigger member 131 is separated from the action spring of the micro switch, thereby realizing the turning off of the micro switch.

[0084] In other embodiments of the present application, the electronic switch 20 can also be a Hall switch, and the trigger member 131 is a magnet. When the magnet moves to the preset position, the magnet triggers the Hall switch to turn on. When the operation member 13 moves in the second direction by the second preset distance, the magnet moves away from the magnetic induction range of the Hall switch, so as to make the Hall switch turn off the circuit before turning on.

[0085] Of course, in other embodiments of the present application, the electronic switch 20 can also be a photoelectric switch, and the trigger 131 is a baffle, when the baffle moves to the preset position, the baffle blocks the trigger light line of the photoelectric switch, so that the baffle triggers the photoelectric switch to turn on. When the operating member 13 moves in the second direction by the second preset distance, the baffle leaves the light line range of the photoelectric switch, so that the photoelectric switch turns off the on circuit before.

[0086] As shown in Figure 8 need to be explained that, in the process of turning on and off of the solid-state circuit switch 30, a processor can also be added to control the turning on of the solid-state circuit switch 30, that is, by judging whether the trigger 131 is in the preset position to trigger the on-off of the electronic switch 20, and then controlling the on-off of the solid-state circuit switch 30.

[0087] As shown in Figure 1 The embodiment of the present application also provides a circuit breaker 1000, the circuit breaker 1000 comprises the hybrid switch 100 for realizing the opening and closing of the circuit breaker 1000 in any of the above-mentioned embodiments.

[0088] Specifically, the operating member 13 is slidably arranged in a shell 200 of the circuit breaker 1000, the movable contact 12 is movably arranged in the shell 200, the fixed contact 11 is directly or indirectly fixed in the shell 200, and the electronic switch 20 is arranged in the shell 200.

[0089] The circuit breaker 1000 provided by the embodiment comprises the hybrid switch 100 in any of the above-mentioned embodiments, and therefore has all the effects of the hybrid switch 100, which will not be described here.
