[0001] The present invention relates to the field of high-voltage circuit breakers, in particular to a closing interlocking mechanism of a circuit breaker. Background Art

[0002] High-voltage circuit breakers (or high-voltage switches) can not only cut off or close the no-load current and load current in the high-voltage circuit, but also cut off the overload current and short-circuit current through the action of the relay protection device when a system fault occurs. It has a fairly complete arc extinguishing structure and sufficient current-breaking capacity. It can be divided into: oil circuit breakers (high-oil circuit breakers, low-oil circuit breakers), sulfur hexafluoride circuit breakers (SF6 circuit breakers), compressed air circuit breakers, vacuum circuit breakers, etc.

[0003] High-voltage circuit breakers are divided into three states according to different working conditions: closed, closed and energy-storing, and open. Existing high-voltage circuit breakers have no protection measures for high-voltage circuit breakers in the closed and energy-storing state, which makes it easy for operators to make mistakes and press the closing button in the closed and energy-storing state, causing accidents. Summary of the Invention

[0004] In order to solve the technical problem in the prior art that high-voltage circuit breakers have no protective measures in the closed energy storage state and are prone to secondary closing, the present invention provides a circuit breaker closing interlocking mechanism to solve the above technical problem.

[0005] The technical solution adopted by the present invention to solve its technical problem is:

[0006] A circuit breaker closing interlocking mechanism is provided, which includes an energy storage cam and a latch that limits the energy storage cam, and is characterized in that the interlocking mechanism includes: a latch connecting plate, the latch connecting plate is fixed to the latch, the latch connecting plate or the latch is linked to the closing button through a connecting rod assembly, and the closing button drives the latch to rotate to unlock through the connecting rod assembly; a limiting plate, the limiting plate is arranged close to the latch connecting plate, the limiting plate and the latch connecting plate cooperate to limit the rotation of the latch, and the limiting plate is driven by a driving module to tighten the latch connecting plate; a deflection plate, the deflection plate is configured to be rotatably installed, and the energy storage cam drives the deflection plate to deflect when it reaches the energy storage holding position, and the deflection plate triggers a position detection module, and the position detection module is used to output an interlocking signal, and the driving module drives the limiting plate to press the latch connecting plate according to the interlocking signal.

[0007] Furthermore, the connecting rod assembly includes: a hinge block, which is configured to be rotatably installed, and one end of the hinge block abuts against the closing button. When the closing button is pressed, the closing button pushes the hinge block to swing to pull the pull rod; a pull rod, one end of the pull rod is hinged on the hinge block, and the other end of the pull rod is hinged on the latch connecting plate. The pull rod drives the latch to deflect through the latch connecting plate.

[0008] Furthermore, the latch connecting plate extends an abutting portion toward the limiting plate, one end of the limiting plate is formed as a limiting portion, and the limiting portion and the abutting portion cooperate with each other to achieve the limitation of the latch connecting plate.

[0009] Furthermore, the driving module includes: an interlocking plate, which is configured to be slidably installed, and the limit plate is fixedly installed on the interlocking plate; a fixed seat, the interlocking plate slides freely relative to the fixed seat, and a driving module for driving the interlocking plate to slide is installed on the fixed seat, and the driving module drives the interlocking plate to move toward the latch plate after receiving the interlocking signal from the position detection module.

[0010] Furthermore, the driving module is an electromagnet, and an elastic member is sleeved on the driving end of the electromagnet. When the electromagnet loses power, the elastic member drives the interlocking plate to move toward the latch connecting plate.

[0011] Furthermore, the middle part of the deflection plate is configured as a hinge point, the first end of the deflection plate is formed with a slope, and the second end of the deflection plate is used to trigger the position detection module. During the energy storage process, when the pin on the energy storage cam passes through the slope of the deflection plate, the deflection plate is deflected, and the second end of the deflection plate follows and triggers the position detection module.

[0012] Furthermore, the closing button includes a button and a button seat, the button is slidably assembled on the button seat, the button seat is configured to be rotatably installed, and the button seat is linked with the main shaft of the circuit breaker through a linkage assembly. When closing, the button seat is driven by the main shaft to deflect and hide.

[0013] Furthermore, the linkage assembly includes: a closing interlock plate, which is configured to be rotatably installed, and the rotating end of the closing interlock plate is hinged to the button seat through a connecting rod, and the rotating end of the closing interlock plate is hinged to the first end of the linkage rod; a linkage rod, the second end of the linkage rod is hinged to the first end of the linkage arm; a linkage arm, the second end of the linkage arm is fixed to the main shaft, and the main shaft drives the button seat to deflect through the linkage arm, the linkage rod, the closing interlock plate and the connecting rod in sequence.

[0014] Furthermore, an extension plate extends from a side of the hinge block away from the closing button, and a closing drive module is provided on one side of the extension plate. The closing drive module is used to drive the hinge block to deflect.

[0015] Furthermore, it is characterized in that the hinge block extends a vertical extension plate toward the closing button, the driving portion of the closing button forms an arc-shaped driving surface, and the vertical extension plate and the arc-shaped driving surface can deflect relative to each other.

[0016] Based on the above structure, the technical effects that can be achieved by the present invention are:

[0017] 1. The closing button of the circuit breaker closing interlocking mechanism of the present invention controls the deflection of the latch connecting plate through the connecting rod assembly. The latch connecting plate is fixedly connected to the latch and the two share a pin shaft to achieve deflection. The deflection of the latch connecting plate drives the latch to deflect. After the latch deflects, the restriction on the energy storage cam is released. The deflection of the energy storage cam pushes the main shaft driving swing arm on the main shaft. After the main shaft driving swing arm rotates, it drives the main shaft to rotate to achieve closing. After closing, the circuit breaker enters the closing energy storage state. The energy storage cam continues to rotate and pushes the deflection plate to deflect. After the deflection plate deflects, it triggers the position detection module. The position detection module outputs a interlocking signal to the drive module. After receiving the signal, the drive module drives the limit plate to press the latch connecting plate tightly. The latch connecting plate is tightened, which means that the latch can no longer be controlled by the closing button to achieve deflection, thereby preventing the circuit breaker from being closed for the second time, thereby avoiding the occurrence of misoperation.

[0018] 2. In the circuit breaker closing interlock mechanism of the present invention, when the energy storage cam pushes the main shaft drive crank arm to rotate the main shaft, the main shaft drives the button seat to deflect through the linkage arm, linkage rod, closing interlock plate and connecting rod in sequence to hide the closing button, making it impossible for the operator to touch the closing button, further reducing the possibility of secondary closing caused by accidentally pressing the closing button.

Unless otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the present invention.

[0036] High-voltage circuit breakers are classified into three operating states: closed, closed and energy-storing, and open. Existing high-voltage circuit breakers lack protective measures for the closed and energy-storing state, making it easy for operators to misoperate. Pressing the closing button during the closed and energy-storing state can cause a secondary closing, leading to accidents. In light of this, the present invention provides a circuit breaker closing interlock mechanism that prevents misoperation during secondary closing.

[0037] like Figure 1-10 As shown, the present invention provides a circuit breaker closing interlocking mechanism, the circuit breaker includes an energy storage cam a and a latch b that limits the energy storage cam a, the interlocking mechanism includes a latch connecting plate 1, a limiting plate 4 that limits the latch connecting plate 1, and a deflection plate 6 that can realize interlocking control of the limiting plate 4, the latch connecting plate 1 is fixed to the latch b, the latch connecting plate 1 or the latch b is linked with the closing button 3 through the connecting rod assembly 2, the closing button 3 drives the latch b to rotate through the connecting rod assembly 2 to unlock, the limiting plate 4 is arranged close to the latch connecting plate 1, the limiting plate 4 and the latch connecting plate 1 cooperate with the rotation of the limiting latch b, the limiting plate 4 is driven by the driving module 53 to tighten the latch connecting plate 1, the deflection plate 6 is configured to be rotatably installed, and the energy storage cam a drives the deflection plate 6 to deflect when it reaches the energy storage holding position, and the deflection plate 6 triggers the position detection module 7, the position detection module 7 is used to output an interlocking signal, and the driving module 5 drives the limiting plate 4 to tighten the latch connecting plate 1 according to the interlocking signal.

[0038] The closing button 3 of the circuit breaker closing interlocking mechanism of the present invention controls the deflection of the latch connecting plate 1 through the connecting rod assembly 2. The latch connecting plate 1 is fixedly connected to the latch b and the two share a pin shaft to achieve deflection. The deflection of the latch connecting plate 1 drives the latch b to deflect. After the latch b deflects, the restriction on the energy storage cam a is released. The deflection of the energy storage cam a pushes the main shaft driving swing arm on the main shaft. After the main shaft driving swing arm rotates, it drives the main shaft to rotate to achieve closing. After closing, the circuit breaker enters the closing energy storage state. The energy storage cam a continues to rotate and pushes the deflection plate 6 to deflect. After the deflection plate 6 deflects, it triggers the position detection module 7. The position detection module 7 outputs a interlocking signal to the drive module 5. After receiving the signal, the drive module 5 drives the limit plate 4 to press the latch connecting plate 1 tightly. The latch connecting plate 1 is tightened, which means that the latch b can no longer be controlled by the closing button 3 to achieve deflection action, thereby preventing the circuit breaker from being closed for the second time, thereby avoiding the occurrence of misoperation. It should be noted that, in the prior art, the latch b is assumed to be capable of self-resetting, and one method of self-resetting is to provide a torsion spring at the hinge of the latch b.

[0039] According to a specific embodiment of the present invention, the closing button 3 includes a button 31 and a button seat 32 . The button 31 is slidably assembled on the button seat 32 , and the button seat 32 is rotatably hinged on the box body base of the circuit breaker.

[0040] According to a specific embodiment of the present invention, the connecting rod assembly 2 includes a hinge block 21 and a pull rod 22. The hinge block 21 is rotatably mounted on the box body base of the circuit breaker. One end of the hinge block 21 abuts against the button 31 of the closing button 3. When the closing button 3 is pressed, the button 31 slides in the button seat 32. While the button 31 slides, it pushes the hinge block 21 to swing. Since the pull rod 22 is also hinged on the hinge block 21, the swing of the hinge block 21 will pull the pull rod 22, and the other end of the pull rod 22 is hinged on the latch plate 1. That is to say, when the pull rod 22 is pulled to move toward the closing button 3, the latch plate 1 will drive the latch b to swing to release the restriction on the energy storage cam a.

[0041] In order to enable the button to better drive the hinge block 21 to deflect, the driving portion 33 of the button forms an arc-shaped driving surface. At the same time, the hinge block 21 extends a vertical extension plate 212 toward the button. The vertical extension plate 212 and the arc-shaped driving surface can deflect relative to each other.

[0042] In this embodiment, the closing trigger can also be electrically driven. For example, the closing drive module 9 is used to drive the hinge block 21 to deflect. Specifically, an extension plate 211 extends from the side of the hinge block 21 away from the button. The closing drive module 9 is provided on one side of the extension plate 211. The triggering part of the closing drive module 9 can push the extension plate 211 to deflect to achieve closing. The closing action after the extension plate 211 is deflected is the same as the action when the closing button 3 drives the closing, and will not be repeated here.

[0043] According to a specific embodiment of the present invention, the latch connecting plate 1 is formed with a limiting plate, a connecting plate and a hinge plate after two sheet metal bendings. The limiting plate extends a supporting portion 11 toward the limiting plate 4. The hinge plate is hinged to the pull rod 22. One end of the limiting plate 4 is formed as a limiting portion 41. The limiting portion 41 cooperates with the supporting portion 11 to achieve the limitation of the latch connecting plate 1.

[0044] According to a specific embodiment of the present invention, the driving module 5 that drives the limit plate 4 to realize the limiting function includes an interlocking plate 51 and a fixed seat 52 fixedly connected to the limit plate 4. The interlocking plate 51 can be freely slidably installed on the fixed seat 52. The fixed seat 52 is set on the box body base of the circuit breaker. A driving module 53 that drives the interlocking plate 51 to slide is also installed on the fixed seat 52. After receiving the interlocking signal from the position detection module 7, the driving module 53 drives the interlocking plate 51 to move toward the latch connecting plate 1, and presses the limiting part 41 of the limit plate 4 against the abutting part 11 of the latch connecting plate 1 to realize the locking limit of the latch b.

[0045] According to a specific embodiment of the present invention, the driving module 53 is preferably an electromagnet, and the driving end of the electromagnet is sleeved with an elastic member. Specifically, the two ends of the elastic member respectively abut against the electromagnet and the interlocking plate 51. When the electromagnet loses power, the elastic member drives the interlocking plate 51 to move toward the latch connecting plate 1.

[0046] In order to enable the energy storage cam a to better drive the deflection plate 6 to trigger the position detection module 7, the middle part of the deflection plate 6 is configured as a hinge point, and a recess is formed at the first end of the deflection plate 6. The surface of the recess close to the first end of the deflection plate 6 is formed as a lower slope 61 to facilitate the passage of the pin on the energy storage cam a. The second end of the deflection plate 6 is used to trigger the position detection module 7. When the first end of the deflection plate 6 is pushed to deflect by the energy storage cam a, the second end of the deflection plate 6 rotates and triggers the position detection module 7.

[0047] According to a specific embodiment of the present invention, the position detection module 7 is preferably a micro switch.

[0048] In order to further reduce the possibility of misoperation, the button seat 32 of the closing button 3 is rotatably mounted on the box body base of the circuit breaker. The button seat 32 is linked to the main shaft of the circuit breaker through the linkage assembly 8. In this way, when closing the circuit, the button seat 32 can be driven by the main shaft to deflect and hide the closing button 3.

[0049] According to a specific embodiment of the present invention, the linkage assembly 8 includes a closing interlock plate 81, a linkage rod 83 and a linkage arm 84. The closing interlock plate 81 is rotatably mounted on the box body base of the circuit breaker. The rotating end of the closing interlock plate 81 is hinged to the button seat 32 through the connecting rod 82. At the same time, the rotating end of the closing interlock plate 81 is also hinged to the first end of the linkage rod 83. The second end of the linkage rod 83 is hinged to the first end of the linkage arm 84. The second end of the linkage arm 84 is fixed to the main shaft. The main shaft drives the button seat 32 to deflect through the linkage arm 84, the linkage rod 83, the closing interlock plate 81 and the connecting rod 82 in sequence to hide the closing button 3.

[0050] Based on the above structure, after the energy storage cam a of the circuit breaker closing interlock mechanism of this embodiment pushes the main shaft drive crank arm to rotate the main shaft to achieve closing, the energy storage cam a passes over the main shaft drive crank arm, and then starts the energy storage action. The energy storage cam a rotates with the energy storage shaft. When the energy storage cam a passes the deflection plate 6, it pushes the deflection plate 6 to deflect and pass over the deflection plate 6, and then the latch b limits the energy storage and maintains it in the energy storage state. At the same time, the deflection of the deflection plate 6 triggers the position detection module 7, and the position detection module 7 sends a chain signal to the drive module 5 to make the electromagnet When the electromagnet loses power, the interlocking plate 51, under the action of the elastic member, drives the limit plate 4 to move toward the latch link plate 1 to limit the latch link plate 1. The limit of the latch link plate 1 means that the latch b fixedly connected to the latch link plate 1 is locked. After the latch b is locked, the closing button 3 can no longer drive the latch b to swing, thereby preventing the closing button 3 from being accidentally pressed and causing a secondary closing. At this time, the electric control closing drive module 9 is also unable to achieve a secondary closing because the closing drive module 9 and the closing button 3 share the same set of connecting rod components 2. On the other hand, when the energy storage cam a pushes the main shaft drive crank arm to rotate the main shaft, the main shaft drives the button seat 32 to deflect and hide the closing button 3 through the linkage arm 84, linkage rod 83, closing interlocking plate 81 and connecting rod 82, so that the operator can no longer touch the closing button 3, further reducing the possibility of the closing button 3 being accidentally pressed and causing a secondary closing.

[0051] It should be understood that the specific embodiments described above are only used to explain the present invention and are not intended to limit the present invention. Obvious changes or modifications derived from the spirit of the present invention are still within the scope of protection of the present invention.
