[0062] The present application provides a longitudinal rotation isolation vacuum circuit breaker, which aims to solve the above technical problems of the prior art.

[0063] The technical solutions of the present application and how the technical solutions solve the above technical problems will be described in detail below with specific examples.

[0064] The present application provides a longitudinal rotation isolation vacuum circuit breaker product, and a structure diagram of the longitudinal rotation isolation vacuum circuit breaker product is shown in Figure 1 and Figure 2 The longitudinal rotation isolation vacuum circuit breaker product comprises a support 10, an operating mechanism 20, a pole column assembly 30, and an induction assembly 40. The operating mechanism 20 comprises a shell 21, a switching linkage mechanism 22, a gear 23, and a grounding switch linkage 24. The pole column assembly 30 is rotationally arranged on the support 10 and the shell 21. The induction assembly 40 comprises an acting element 41, a closing confirmation inductor 42, and an opening confirmation inductor 43. The closing confirmation inductor 42 and the opening confirmation inductor 43 are arranged on the shell 21. The pole column assembly 30 rotates and drives the acting element 41 to act on the closing confirmation inductor 42 and the opening confirmation inductor 43 respectively, so as to confirm the closing and opening states of the pole column assembly 30.

[0065] In the present application, the acting element 41 interacts with the closing confirmation inductor 42 and the opening confirmation inductor 43 respectively, so as to confirm the closing and opening states of the pole column assembly 30. The closing and opening state confirmation can effectively prevent misoperation and improve the use safety of the isolation vacuum circuit breaker.

[0066] Optionally, the acting member 41 is movably arranged relative to the shell 21, and a movement path of the acting member 41 defines the movement induction path, and the closing confirmation inductor 42 and the opening confirmation inductor 43 are arranged on the movement induction path of the acting member 41 respectively; wherein, when the pole column assembly 30 rotates in the forward direction or the reverse direction to close or open, the acting member 41 is driven to reciprocate on the movement induction path, and the acting member 41 switches to act on the closing confirmation inductor 42 or the opening confirmation inductor 43 to confirm the closing or opening state of the pole column assembly 30.

[0067] In the prior art, the pole column assembly 30 rotates on the support 10 and the shell 21 and has a closing position (vertical) and an opening position (horizontal), which will not be described here.

[0068] It can be understood that the pole column assembly 30 drives the acting member 41 to move on the shell 21. When the pole column assembly 30 is in the closing state, the acting member 41 moves to the position of the closing confirmation inductor 42, and the two inductors are inducted to perform electrical feedback. Similarly, the acting member 41 moves to the position of the opening confirmation inductor 43, and the two inductors are inducted to perform electrical feedback.

[0069] In the above, the inductor can be externally connected to an indicating lamp or a display system to be used as a display for the closing or opening state of the isolating switch.

[0070] For a more detailed description, in combination with the prior art, the pole column assembly 30 includes a longitudinal beam 31, three-phase pole columns 32, a screw rod set 33, a driving shaft 34 and a rotating fork 35; one end of the longitudinal beam 31 is rotatably arranged on the shell 21, and the other end is rotatably arranged on the support 10, the three-phase pole columns 32 are arranged on the longitudinal beam 31, the rotating fork 35 has a plug-in opening 351 arranged on one end thereof, the rotating fork 35 is connected to the longitudinal beam 31 at one end, and the plug-in opening 351 is arranged towards the direction away from the axis of the rotating shaft of the longitudinal beam 31; the screw rod set 33 includes a screw rod 331 and a platform 332, the screw rod 331 is rotatably arranged on the shell 21 and is arranged along the radial direction of the rotating shaft of the longitudinal beam 31, and the platform 332 is movably arranged on the screw rod 331.

[0071] It can be known that the specific components of the pole column assembly 30 and the operating mechanism 20 and the connection between the components are all prior art, and will not be described in more detail here. The length direction of the plug-in opening 351 of the rotating fork 35 is perpendicular to the length direction of the longitudinal beam 31, and preferably, the driving shaft 34 is plugged into the opening of the plug-in opening 351. The driving shaft 34 of the embodiment is movably connected to the plug-in opening 351, and the rotation of the longitudinal beam 31 is driven by the linear motion of the driving shaft 34, so that the platform 332 can also be used to realize the linear driving of other components. This is prior art, which will not be described here.

[0072] Optionally, the acting element 41 comprises a sliding plate 411; the sliding plate 411 is movably arranged on the shell 21 and linearly moves on the shell 21, and the path of the linear movement of the sliding plate 411 is a linear sensing path; the closing confirmation sensor 42 comprises a linear closing micro switch group, and the linear closing micro switch group comprises a first linear closing micro switch 421; the opening confirmation sensor 43 comprises a linear opening micro switch group, and the linear opening micro switch group comprises a first linear opening micro switch 431; the first linear closing micro switch 421 is arranged on the shell 21 and located at the bottom of the linear sensing path, and the first linear opening micro switch 431 is arranged on the shell 21 and located at one side of the linear sensing path.

[0073] It needs to be explained in the embodiment that the existing micro switch is provided with an elastic contact, which can be arranged in the linear sensing path of the sliding plate 411, and the sliding plate 411 can continuously switch and abut between the first linear closing micro switch 421 and the first linear opening micro switch 431 when reciprocating, so as to electrically feedback the opening or closing state of the disconnecting switch.

[0074] In particular, the sliding plate 411 is arranged on the top of the platform 332, and specifically, the platform 332 passes through the top of the shell 21 and reaches outside the shell 21, and the sliding plate 411 is arranged outside the shell 21 and moves with the platform 332 to be movably arranged relative to the shell 21. The first linear closing micro switch 421 is arranged at the bottom of the linear sensing path, which corresponds to the bottom of the sliding plate 411 and the abutment with the first linear closing micro switch 421.

[0075] Optionally, the linear closing micro switch group further comprises a second linear closing micro switch 422, and the linear opening micro switch group further comprises a second linear opening micro switch 432; the second linear closing micro switch 422 and the second linear opening micro switch 432 are both arranged on the shell 21 and located at one side of the linear sensing path.

[0076] In the embodiment, the second linear closing micro switch 422 and the second linear opening micro switch 432 are added to complete the double-point confirmation of the opening and closing of the disconnecting switch in the linear sensing path, and the more confirmation points, the stronger the reliability and the higher the safety of the confirmation device.

[0077] It needs to be explained in combination with the above that the arrangement position of the micro switch relative to the sliding plate 411 is not unique, and can be adjusted according to the overall layout of the isolation vacuum circuit breaker, and the micro switch can be arranged on one side, the top or the bottom of the sliding plate 411, etc., and the arrangement is subject to the condition that the two can abut.

[0078] Optionally, the first linear opening microswitch 431, the second linear opening microswitch 432, and the second linear closing microswitch 422 are arranged along the linear induction path in sequence, and the first linear closing microswitch 421 is located between the second linear opening microswitch 432 and the second linear closing microswitch 422.

[0079] In combination with the prior art, for the convenience of description, the definition of the pole assembly 30 being reversed (counterclockwise) to the horizontal state is the disconnection of the disconnecting switch, and vice versa, the positive rotation (clockwise) to the vertical state is the closing of the disconnecting switch. The first linear opening microswitch 431, the second linear opening microswitch 432, and the second linear closing microswitch 422 are arranged along the linear induction path from left to right in sequence.

[0080] Optionally, the sliding plate 411 comprises a bottom plate 4111 and an abutting protrusion 4112 arranged on the bottom plate 4111; the bottom plate 4111 is connected with the pole assembly 30, the first linear closing microswitch 421 is arranged below the bottom plate 4111, and the abutting protrusion 4112 acts on the linear closing microswitch group and the linear opening microswitch group respectively.

[0081] Illustratively, the first linear closing microswitch 421 abuts against the bottom surface of the bottom plate 4111. In this way, the first linear opening microswitch 431, the second linear opening microswitch 432, and the second linear closing microswitch 422 abut against the abutting protrusion 4112.

[0082] Preferably, the abutting protrusion 4112 is arranged on one side of the top of the bottom plate 4111, and the cross section between the two forms an L-shaped structure.

[0083] Optionally, the number of the abutting protrusions 4112 is equal to the number of the linear closing microswitch group and the linear opening microswitch group, and each linear closing microswitch group and each linear opening microswitch group is respectively arranged to act on an independent abutting protrusion 4112.

[0084] Exemplarily, the first linear tripping microswitch 431, the second linear tripping microswitch 432 and the second linear closing microswitch 422 are correspondingly provided with three abutting protrusions 4112, for the convenience of description, the three abutting protrusions 4112 are named as protrusion one, protrusion two and protrusion three respectively. Specifically, when the circuit breaker is in the tripping position, the protrusion one and the protrusion two abut against the first linear tripping microswitch 431 and the second linear tripping microswitch 432 respectively, at this time, the protrusion three is separated from the second linear closing microswitch 422, and the bottom plate 4111 is separated from the first linear closing microswitch 421; when the circuit breaker is in the closing position, the protrusion three abuts against the second linear closing microswitch 422, the bottom plate 4111 abuts against the first linear closing microswitch 421, the protrusion one is separated from the first linear tripping microswitch 431, and the protrusion two is separated from the second linear tripping microswitch 432, thereby realizing the switching induction of the disconnector between the tripping and the closing. The significance of providing multiple abutting protrusions 4112 in the embodiment lies in avoiding too long travel of the bottom plate 4111, which is conducive to compressing the space of the isolation vacuum circuit breaker and realizing miniaturization of the isolation vacuum circuit breaker.

[0085] In addition, if the linear closing microswitch group only includes the second linear closing microswitch 422, and the linear tripping microswitch group only includes the first linear tripping microswitch 431 or the first linear tripping microswitch 431, at this time, two abutting protrusions 4112 can be provided as described above to switch the tripping and closing. Alternatively, only one abutting protrusion 4112 is provided, and the second linear closing microswitch 422 and the first linear tripping microswitch 431 (or the first linear tripping microswitch 431) can take turns to induce the one abutting protrusion 4112.

[0086] Alternatively, the acting member 41 further includes an acting plate 412; the acting plate 412 is arranged on the pole assembly 30 and rotates synchronously with the pole assembly 30, and the path of the rotating movement of the acting plate 412 is defined as a curved induction path; the closing confirmation inductor 42 includes a curved closing microswitch group, and the curved closing microswitch group further includes a curved closing microswitch 423; the tripping confirmation inductor 43 further includes a curved tripping microswitch group, and the curved tripping microswitch group includes a curved tripping microswitch 433; the curved closing microswitch 423 and the curved tripping microswitch 433 are respectively arranged on the housing 21 and respectively located on the curved induction path.

[0087] Exemplarily, one end of the acting plate 412 is connected to the pole assembly 30, and the other end is a free end extending away from the rotating shaft of the pole assembly 30, and the curved closing microswitch 423 and the curved tripping microswitch 433 of the embodiment are arranged on the path of the free end. More specifically, the acting plate 412 is arranged on the longitudinal beam 31.

[0088] In addition, the curve closing micro switch 423 and the curve opening micro switch 433 can also be arranged on one side of the action plate 412. The position arrangement of the micro switch in the embodiment can be arranged according to the space area.

[0089] Optionally, the number of the action plate 412 is two, and the number of the curve closing micro switch 423 and the curve opening micro switch 433 is one respectively.

[0090] One action plate 412 is used for acting on the curve closing micro switch 423, and the other action plate 412 is used for acting on the curve opening micro switch 433.

[0091] In combination with the foregoing, the angle turned between the opening and closing of the disconnector is 90°. In the embodiment, the curve closing micro switch 423 and the curve opening micro switch 433 are arranged in central and left-right symmetry about the rotation center of the pole assembly 30 in the horizontal position. The extension lines of the lengths of the two action plates 412 respectively pass through the rotation center and form a 90° included angle.

[0092] Specifically, the action state of the two action plates 412 is that when the disconnector is in the opening state, one of the action plates 412 acts on the curve opening micro switch 433, along the rotation direction of the pole assembly 30, and the other action plate 412 is located between the curve opening micro switch 433 and the curve closing micro switch 423, and at the same time below the curve opening micro switch 433 and the curve closing micro switch 423. After the pole assembly 30 rotates 90° clockwise, the disconnector is in the closing state, at which time the above-mentioned one of the action plates 412 is separated from the curve opening micro switch 433, and the other action plate 412 acts on the curve closing micro switch 423 to abut, so as to form the induction of state switching.

[0093] In addition, the number of the action plate 412 also includes that the number of the action plate 412 is one, so that the position included angle between the curve opening micro switch 433 and the curve closing micro switch 423 is 90°, so as to realize the function that one action plate 412 acts on the curve opening micro switch 433 and the curve closing micro switch 423.

[0094] Based on this, the above-mentioned sliding plate 411, the first straight-line closing micro switch 421, the second straight-line closing micro switch 422, the first straight-line opening micro switch 431, and the second straight-line opening micro switch 432 form a group of confirmation groups. The action plate 412, the curve opening micro switch 433, and the curve closing micro switch 423 form another group of confirmation groups. Thus, the two groups of confirmation groups can realize signal confirmation and signal feedback at the same time, realizing multiple insurance.

[0095] Optionally, referring to Figures 3-8The opening and closing linkage mechanism 22 is connected to the pole assembly 30 and located in the shell 21, the gear 23 is movably arranged in the shell 21, the shell 21 is provided with a handle passage, and the grounding switch linkage 24 is movably arranged in the shell 21 and located on the handle passage; wherein, when the pole assembly 30 is in the closing state, the grounding switch linkage 24 is acted and limited, the gear 23 is forced to move away from the handle passage, and the external handle can enter the handle passage; when the pole assembly 30 is in the opening state, the external handle exits the handle passage, the grounding switch linkage 24 is moved to act and limit the gear 23, the gear 23 blocks the handle passage to prevent the external handle from being inserted into the handle passage.

[0096] In the embodiment, the focus is on the mutual defense and interlocking among the opening and closing linkage mechanism 22, the gear 23 and the grounding switch linkage 24, so as to prevent misoperation.

[0097] In addition, according to the prior art, it can be known that the isolation vacuum circuit breaker is installed in the cabinet body of the switch cabinet, and the isolation vacuum circuit breaker can be pushed into or pulled out of the cabinet body (not shown) by pulling. Importantly, after the isolation vacuum circuit breaker is pushed into the cabinet body, the grounding switch linkage 24 will be linked with the grounding switch linkage in the cabinet body.

[0098] In addition, after the isolation vacuum circuit breaker is pushed into the cabinet body, one side of the shell 21 is flush with the outside of the cabinet body, and the handle passage is arranged on the side of the shell 21 flush with the cabinet body, so that the operating handle can be inserted into the handle passage from the outside.

[0099] Furthermore, the opening and closing of the pole assembly 30 of the embodiment affects the linkage of the gear 23 and the grounding switch linkage 24, and at the same time, the induction assembly 40 is also synchronized according to the foregoing, which provides the function of state confirmation for the opening and closing state of the pole assembly 30 of the embodiment, and ensures the safety of operation.

[0100] Optionally, the opening and closing linkage mechanism 22 is driven to rotate by the pole assembly 30, the opening and closing linkage mechanism 22 has an opening position and a closing position in the rotation path, the blocking position and the avoiding position are arranged in the activity path of the blocking member 23; the activity path of the grounding switch linkage 24 has a coincident area with the activity path of the opening and closing linkage mechanism 22 and the blocking member 23; when the opening and closing linkage mechanism 22 is in the closing position, the activity path of the grounding switch linkage 24 is entered, the opening and closing linkage mechanism 22 limits the movement of the grounding switch linkage 24 on the shell 21 to prevent the external grounding switch from closing, the grounding switch linkage 24 leaves the activity path of the blocking member 23, the blocking member 23 moves to the avoiding position to avoid, and the external handle can enter the handle passage; when the opening and closing linkage mechanism 22 is in the opening position, the activity path of the grounding switch linkage 24 is separated to release the grounding switch linkage 24, the external handle exits the handle passage, the blocking member 23 in the blocking position moves to the avoiding position, the grounding switch linkage 24 is operated to enter the activity path of the blocking member 23 and link the external grounding switch closing, the grounding switch linkage 24 blocks the movement path of the blocking member 23 to limit the blocking member 23 in the avoiding position, and the blocking member 23 in the avoiding position blocks the handle passage to prohibit the external handle from inserting into the handle passage.

[0101] For example, the shell 21 has an inner cavity. The opening and closing linkage mechanism 22 and the blocking member 23 are arranged in the inner cavity. According to the use regulations of the high-voltage equipment, the grounding switch is not allowed to close when the disconnector is not opened, and the operating handle is not allowed to enter the handle passage when the grounding switch is not opened, and the disconnector is closed. In the above, the opening and closing linkage mechanism 22 is provided with an opening position and a closing position. When the opening and closing linkage mechanism 22 is in the closing position (i.e. the disconnector is closed), the opening and closing linkage mechanism 22 enters the activity path of the grounding switch linkage 24, the grounding switch linkage 24 limits the movement or locks the grounding switch linkage 24 to prevent the grounding switch linkage 24 from operating the grounding switch closing. Conversely, when the opening and closing linkage mechanism 22 is in the opening position (i.e. the disconnector is opened), it releases the limitation or locking of the grounding switch linkage 24, the grounding switch linkage 24 restores the movement, and the grounding switch linkage 24 can operate the grounding switch closing.

[0102] In the above, when no external force is applied, the blocking piece 23 is in the blocking position, when the grounding switch linkage 24 operates the grounding switch to close, it moves to the active path of the blocking piece 23, blocks the movement of the blocking piece 23 from the blocking position to the avoiding position, the blocking piece 23 blocks the handle passage in the blocking position, so as to block the operation of the handle into the handle passage and prevent the closing of the disconnecting switch. Conversely, when the grounding switch linkage operates the grounding switch to open, the grounding switch linkage 24 is out of the active path of the blocking piece 23, the blocking piece 23 can move from the blocking position to the avoiding position to clear the handle passage, at this time the handle can enter the handle passage and operate the disconnecting switch to close.

[0103] Further, the grounding switch linkage 24 coincides with the active path of the opening and closing linkage mechanism 22 and the blocking piece 23, and the three play a interlocking effect.

[0104] In other words, the grounding switch linkage 24 can be slidably arranged on the shell 21. According to the above, the grounding switch linkage 24 is limited by the opening and closing linkage mechanism 22. It can be clearly known that whether the grounding switch linkage 24 can enter the active path of the blocking piece 23 depends on the limitation of the linkage plate assembly 221 to the grounding switch linkage 24. When the opening and closing linkage mechanism is in the closing position, the linkage plate assembly 221 limits the movement of the grounding switch linkage 24, that is, limits the operation of the grounding switch to close. When the linkage plate assembly 221 is in the opening position, the linkage plate assembly 221 releases the active path of the grounding switch linkage 24, the grounding switch linkage 24 operates the grounding switch to close and enters the active path of the blocking piece 23, the grounding switch linkage 24 prevents the blocking piece 23 from moving from the blocking position to the avoiding position, and further blocks the handle passage to prevent the disconnecting switch from closing. Thus, the forced interlocking of the anti-misoperation is realized, and the damage to the power equipment or personal injury caused by misoperation during the operation and maintenance of the equipment is prevented.

[0105] Optionally, the opening and closing linkage mechanism 22 comprises a linkage plate assembly 221, and the linkage plate assembly 221 comprises a source driving plate 2211 and a walking plate component 2212; the walking plate component 2212 is movably arranged on the shell 21, and the source driving plate 2211 acts on the walking plate component 2212 and has an opening position and a closing position; when the source driving plate 2211 is in the closing position, the walking plate component 2212 is located in the movement path of the grounding switch linkage 24 to limit the movement of the grounding switch linkage 24 on the shell 21; when the source driving plate 2211 in the closing position moves to the opening position, it acts on the walking plate component 2212, and the walking plate component 2212 is out of the movement path of the grounding switch linkage 24.

[0106] For example, in the embodiment, the walking plate component 2212 is used as a block in the movement path of the grounding switch linkage 24, and the source driving plate 2211 is a driving plate, which does not need to be in contact with the grounding switch linkage 24, avoiding damage.

[0107] For example, the longitudinal beam 31 of the pole assembly 30 is provided with a connecting rod 50, and the source driving plate 2211 is arranged on the connecting rod 50. The power source mentioned above is the pole assembly 30 in the embodiment. According to the prior art, it can be known that when the source driving plate 2211 is located at the open position, the pole assembly is rotated to the horizontal state and the pole assembly is powered off; when the source driving plate 2211 is located at the closed position, the pole assembly is rotated to the vertical state and the pole assembly is powered on.

[0108] Optionally, the walking plate component 2212 comprises a walking plate 22121 and a first torsional spring 22122; the walking plate 22121 is rotationally arranged on the shell 21, and the first torsional spring 22122 is arranged on the shell 21 and acts on the walking plate 22121. The walking plate 22121 comprises an acting end 221211 and a limiting end 221212. The source driving plate 2211 acts on the acting end 221211 to drive the walking plate 22121 to rotate. The limiting end 221212 is used to act on the grounding switch linkage 24.

[0109] In addition, the gear component 23 comprises a gear plate 231 and a second torsional spring 232; the gear plate 231 is rotationally arranged on the shell 21, and the second torsional spring 232 is arranged on the shell 21 and acts on the gear plate 231. The gear plate 231 comprises a gear end 2311 and an abutting end 2312. The gear end 2311 is used to block the handle channel. The abutting end 2312 is used to act on the grounding switch linkage 24.

[0110] For example, a vertical partition plate 2100 is arranged in the cavity of the shell 21. The gear component 23, the opening and closing linkage mechanism 22, and the grounding switch linkage 24 are arranged on one side of the partition plate 2100. The walking plate 22121 and the gear plate 231 are rotationally connected between the side plates of the bracket through bolts. Preferably, one end of each bolt is connected to the middle part of the walking plate 22121 and the gear plate 231, respectively. The bolt is clamped between the two sides of the side wall through at least two nuts to limit the bolt. The shell 21 is provided with a through hole 210 for inserting the operating handle. The through hole 210 communicates the operating channel with the outside.

[0111] In the embodiment, the gear plate 231 rotates in the horizontal direction. The partition plate 2100 is provided with a second through hole. The second torsional spring 232 is sleeved on the bolt of the gear plate 231. The two ends of the second torsional spring 232 abut on the two opposite sides of the gear plate 231, respectively. The abutting end 2312 passes through the second through hole to the other side of the partition plate 2100.

[0112] In addition, the spacer 2100 is provided with a first through hole, and the limiting end 221212 of the walking plate 22121 passes through the first limiting hole to the other side of the spacer 2100. The first torsion spring 22122 is sleeved on the bolt connected with the walking plate 22121, one end of the first torsion spring 22122 abuts against the side wall of the spacer 2100, the other end is arranged in the walking plate 22121, and the high end is located between the limiting end 221212 and the bolt connected with the walking plate 22121.

[0113] The linkage process of the above-mentioned constraint interlocking device is as follows: when the grounding switch is opened, the source driving plate 2211 is in the closed position as the initial state, at this time, the walking plate 22121 is in a horizontal state under the action of the first torsion spring 22122, the limiting end 221212 passes through the first through hole, and the top of the walking plate 22121 abuts against the top wall of the first through hole.

[0114] At this time, one end of the source driving plate 2211 is connected with the external starting source, and the other end is located below the acting end 221211. The gear 23 is located in the blocking position, the gear end 2311 is located in the operation channel, and the abutting end 2312 passes through the second through hole to the other side of the spacer 2100.

[0115] Optionally, the grounding switch linkage member 24 comprises an upper stop plate 241 and a lower stop plate 242; the upper stop plate 241 and the lower stop plate 242 are movably arranged on the shell 21 respectively, the lower stop plate 242 is used for linkage to the external grounding switch, and the upper stop plate 241 is used for entering the movable path of the gear 23 to block the gear 23 from moving to the avoiding position.

[0116] In the embodiment, the upper stop plate 241 and the lower stop plate 242 can be independently arranged on the shell 21 respectively, and synchronous linkage can be realized between the two through different motors and other driving structures under the control of the control circuit.

[0117] In other embodiments, the grounding switch linkage 24 can include an upper baffle 241, a lower baffle 242, and a connecting rod (not shown), and the upper baffle 241 and the lower baffle 242 are connected by the connecting rod. The grounding switch is initially in an open state, at which time the disconnecting switch is in an open state, the upper baffle 241 is below the abutting end 2312, and the top of the lower baffle 242 is below the limiting end 221212 (the top of the lower baffle 242 is a certain distance from the bottom of the limiting end 221212, so that the limiting end 221212 can be turned downward and into the first through hole), at which time the operating handle inserted into the through hole 210 enters into abutment with the blocking end 2311, the blocking plate 231 as a whole is turned in the clockwise direction of the horizontal plane (the second torsional spring 232 is compressed under stress), so the blocking end 2311 avoids (the blocking piece 23 is in the avoidance position), the operating handle inserted into the handle passage to perform the closing operation of the disconnecting switch, the source driving plate 2211 reaches the closed position, at which time the other end of the source driving plate 2211 is disengaged from the walking limiting plate 22121, and the limiting end 221212 of the walking limiting plate 22121 is blocked on the top of the lower baffle 242, so that the lower baffle 242 cannot move upward to close the grounding switch.

[0118] Conversely, when the operating handle exits the operating passage, the second torsional spring 232 releases and rebounds to push the blocking plate 231 as a whole to turn in the counterclockwise direction of the horizontal plane back to the original position.

[0119] When the source driving plate 2211 reaches the open position, the other end of the source driving plate 2211 abuts against the acting end 221211, the walking limiting plate 22121 is turned in the clockwise direction in the vertical plane, and the limiting end 221212 is turned downward and into the first through hole (the first torsional spring 22122 is compressed under stress), at which time the grounding switch linkage 24 is pushed to move upward to operate the grounding switch to close, that is, the upper baffle 241 moves upward and blocks the second through hole, that is, the upper baffle 241 limits the side of the abutting end 2312. At this time, the operating handle inserted into the through hole 210 enters into abutment with the blocking end 2311, the upper baffle 241 blocks the abutting end 2312, and the blocking plate 231 cannot be turned, so the blocking end 2311 cannot avoid, preventing the operating handle from being inserted, and the disconnecting switch cannot be closed, thereby preventing misoperation.

[0120] In summary, the restraint interlocking device of the embodiment has the advantages of short transmission path, simple structure, strong restraint, and high reliability.

[0121] In addition, as previously described, after the isolation vacuum circuit breaker is pushed into the cabinet, the lower baffle 242 at this position protrudes from the bottom of the shell 21 and is automatically aligned and inserted with the grounding switch linkage (including but not limited to automatic alignment and insertion of the plug rod and the plug hole, or manual locking, but note that manual locking needs to be manually unlocked).

[0122] Optionally, the walking plate 22121 is provided with a plug protrusion 221210; when the limiting end 221212 is located in the movement path of the grounding switch linkage 24, the plug protrusion 221210 is plugged into the shell 21.

[0123] Optionally, the top wall of the first through hole of the aforementioned partition plate 2100 is provided with a plug hole matched with the plug protrusion 221210; the plug protrusion 221210 is plugged into the plug hole to prevent the walking plate 22121 from shaking in the horizontal direction, thereby ensuring the reliability of the walking plate 22121 in limiting the grounding switch linkage 24.

[0124] Optionally, the gear plate 231 comprises a first supporting rod 2301 and a second supporting rod 2302 connected with each other; the first supporting rod 2301 and the second supporting rod 2302 are arranged to form an included angle.

[0125] Optionally, the aforementioned gear end 2311 is one end of the first supporting rod 2301, and the abutting end 2312 is one end of the second supporting rod 2302. The gear plate 231 is arranged to have two supporting rods with an included angle, which can effectively reduce the overall length of the gear plate 231 and reduce the occupied space. In combination with the foregoing, one end of the second torsion spring 232 acts on the inner side of the second supporting rod 2302, and the other end acts on the outer side of the first supporting rod 2301.

[0126] Optionally, the included angle between the first supporting rod 2301 and the second supporting rod 2302 is between 110° and 150°.

[0127] Preferably, the included angle between the first supporting rod 2301 and the second supporting rod 2302 is 120°; other angles such as 110°, 115°, 125°, 135°, 140°, 145°, and 150° can be selected according to design needs, which will not be repeated here.
