[0002] The applicant's prior patent CN202321023758.8 discloses a quickly cut-off rotary switch, including a housing, an operating mechanism, and an energy storage mechanism. The energy storage mechanism cooperates with a drive device. Under normal circumstances, the energy storage mechanism stores energy, and the knob realizes the opening and closing of the switch assembly through the operating mechanism. In the event of a circuit fault, the energy storage mechanism releases energy to drive the operating shaft in the closed state to rotate to the disconnected state, thereby realizing rapid opening and cutting off the circuit.

Therefore, the directions and positions used are used to explain and understand the present invention, but are not intended to limit the scope of protection of the present invention.

[0045] Embodiment 1:

[0046] This embodiment provides a rotary isolating switch, such as Figure 1-Figure 5As shown, it includes a housing assembly 100 and an operating mechanism, an energy storage mechanism, and a first drive mechanism 400 disposed in the housing assembly 100. The specific structures of the operating mechanism, the energy storage mechanism, and the first drive mechanism 400 are basically the same as those of the patent CN202321023758.8 previously disclosed by the applicant.

[0047] Specifically, the operating mechanism includes a stopper, a first operating shaft 210, a first energy storage element 220, and an operating seat 230 which are arranged in sequence. The first energy storage element 220 is arranged between the first operating shaft 210 and the operating seat 230, and is used to store energy when the first operating shaft 210 rotates to open and close the switch, and to release energy to drive the operating seat 230 to rotate when the first operating shaft 210 completes the opening and closing action or is close to completing the opening and closing action. The specific matching structure between the stopper, the first operating shaft 210, the first energy storage element 220, and the operating seat 230 is not elaborated here. For details, please refer to the relevant structure recorded in the patent CN202321023758.8 specification.

[0048] Specifically, the energy storage mechanism includes a second energy storage element, a second operating shaft 310, a rack 320, and an energy storage lock block 330. The second operating shaft 310 is coaxially plugged with the first operating shaft 210 and the two are circumferentially linked. At the same time, the second operating shaft 310 passes through the shell to be connected with a manual operating handle or an electric operating mechanism to achieve the opening and closing operation. The second energy storage element is a torsion spring sleeved on the second operating shaft 310 and its two ends are respectively matched with the inner wall of the shell and the rack 320. The energy storage lock block 330 is used to lock the second energy storage element in the energy storage state. The second operating shaft 310 has a gear structure meshing with the rack 320. When the energy storage lock block 330 moves to release the locking effect on the second energy storage element in the energy storage state, the second energy storage element in the energy storage state releases energy to push the rack 320, so that the second operating shaft 310 and the first energy storage element 220 rotate to achieve opening and power off. The specific matching structure between the second energy storage element, the second operating shaft 310, the rack 320, and the energy storage lock block 330 is not elaborated here. For details, please refer to the relevant structure recorded in the patent CN202321023758.8 specification.

[0049] The first driving mechanism 400 is an electromagnetic driving mechanism, and is provided with a first port 410 for receiving a control signal. The control signal can cause the first driving mechanism 400 to actuate the energy storage lock block 330. Specifically, a connecting rod 500 is provided between the first driving mechanism 400 and the energy storage lock block 330. Figure 5As shown, the connecting rod 500 is provided with a first hinged portion 510 for being hingedly connected to the housing assembly 100, a first pushing portion 520 arranged corresponding to the first driving mechanism 400, and a driving portion 530 arranged corresponding to the energy storage lock block 330. The first driving mechanism 400 drives the energy storage lock block 330 to move to a position to release the locking effect on the second energy storage element in the energy storage state through the transmission of the connecting rod 500, and the energy storage mechanism releases energy to achieve opening and power off.

[0050] At the same time, a reset transmission member 600 is provided between the first drive mechanism 400 and the second operating shaft 310 to reset the first drive mechanism 400, that is, when the second operating shaft 310 is rotated from the open position to the closed position, the first drive mechanism 400 can be reset, the second energy storage element can be stored, and the switch unit can be closed. The specific structure of the reset transmission member 600 can refer to the relevant structure recorded in the patent CN202111031928.2 specification, which will not be elaborated here.

[0051] After a fault occurs, a control signal is sent to the first drive mechanism 400 to release the energy of the second energy storage element, thereby quickly opening the switch and shutting off the power. After the fault is eliminated, the second operating shaft 310 is rotated to close the switch and reset the second energy storage element and the first drive mechanism 400.

[0052] In this embodiment, on the basis of the above structure, a padlock mechanism is added in the housing assembly 100, through which the switch cannot be closed and reset, avoiding misoperation. When the fault is not eliminated and solved, the switch is closed and energized. Specifically, the padlock mechanism includes a second drive mechanism 700, which is provided with a second port 710 for receiving a control signal. The second drive mechanism 700 cooperates with the operating mechanism. When the second drive mechanism 700 receives the control signal, it acts to prevent the operating mechanism from rotating from the open position to the closed position, avoiding misoperation after a major fault occurs.

[0053] Specifically, Figure 2 As shown, a swing rod 800 is provided between the second driving mechanism 700 and the first energy storage element 220. When the second driving mechanism 700 is actuated, the swing rod 800 cooperates with the first energy storage element 220 in the off state, so that the first energy storage element 220 cannot be actuated.

[0054] Specifically, the first energy storage element 220 is an energy storage torsion spring, which includes two torsion arms, which move successively during the opening and closing actions to complete energy storage / energy release. Figure 3As shown, the middle part of the swing lever 800 is provided with a second hinged portion 810 hingedly matched with the housing assembly 100, a third pushing portion 820 corresponding to the second driving mechanism 700, and a locking portion 830 corresponding to the first energy storage element 220, and a first action spring 840 is provided to act on the swing lever 800 to keep the locking portion 830 away from the first energy storage element 220 and not interfere with its normal action. When the second driving mechanism 700 receives a control signal to cause it to act, as shown in FIG. Figure 2 As shown, the second driving mechanism 700 drives the third pushing part 820, and the locking part 830 moves downward to hook a torsion arm of the first energy storage element 220, so that the first energy storage element 220 cannot move, and then the entire operating mechanism cannot perform the closing action, forming a padlock function.

[0055] Furthermore, the second driving mechanism 700 of the present embodiment includes an electromagnetic coil fixing member 720 and an electromagnetic driving block 730 to which an electromagnetic coil is fixed, and a second action spring 740 is provided between the electromagnetic coil fixing member 720 and the electromagnetic driving block 730. In the present embodiment, the electromagnetic coil fixing member 720 is a shell made of a magnetically conductive material such as low carbon steel, electrical pure iron, etc., the electromagnetic coil is fixed in the shell, and the electromagnetic driving block 730 is at least partially made of a permanent magnet; there is an adsorption force and an absorption force between the shell made of the magnetically conductive material and the electromagnetic driving block 730. The attachment force is greater than the thrust of the second action spring 740 after energy storage, ensuring that the shell made of magnetic conductive material and the electromagnetic drive block 730 maintain an adsorption relationship in the initial state; when the second drive mechanism 700 receives the padlock control signal, the electromagnetic coil is energized to form a magnetic field and the direction of the magnetic field forms a repulsive force away from the electromagnetic coil on the electromagnetic drive block 730, and the sum of the repulsive force and the thrust of the second action spring 740 after energy storage is greater than the attachment force between the shell made of magnetic conductive material and the electromagnetic drive block 730, so that the electromagnetic drive block 730 can be pushed to move.

[0056] Furthermore, in this embodiment, a manual reset mechanism is provided for the second driving mechanism 700, specifically, Figure 1 , Figure 2 As shown, a push rod 750 is provided below the electromagnetic driving block 730 of the second driving mechanism 700 , and the push rod 750 passes through the housing assembly 100 . By pressing the push rod 750 , the electromagnetic driving block 730 can be reset and re-adsorbed onto the electromagnetic coil fixing member 720 .

[0057] Furthermore, the connecting rod 500 of this embodiment is further provided with a second pushing portion 540 corresponding to the second driving mechanism 700. Figure 4 As shown, the second driving mechanism 700 moves to push the second pushing portion 540, and drives the energy storage lock block 330 to move to a position to release the locking effect on the second energy storage element in the energy storage state through the transmission of the connecting rod 500.

[0058] In this embodiment, the first drive mechanism 400 and the second drive mechanism 700 can both release the energy of the energy storage mechanism, thereby realizing the opening and power off. Only the first drive mechanism 400 is in motion, and the closing and energy storage mechanism energy storage reset can be realized by turning the knob. Only the second drive mechanism 700 is in motion, and the closing and energy storage mechanism energy storage reset cannot be realized by turning the knob. The second drive mechanism 700 must be manually pushed to reset by the push rod 750 before the closing and energy storage mechanism energy storage reset can be realized by turning the knob. When this embodiment is used, the first drive mechanism 400 or the second drive mechanism 700 can be selected to act according to the severity of the fault, or the first drive mechanism 400 and the second drive mechanism 700 can act synchronously, or the first drive mechanism 400 can act and the second drive mechanism 700 can be controlled by remote signals. The first drive mechanism 400 and the second drive mechanism 700 can be automatically actuated by different fault signals, or the first drive mechanism 400 and the second drive mechanism 700 can be manually actuated by remotely sending control signals based on the fault conditions.

[0059] Embodiment 2:

[0060] This embodiment provides a rotary isolating switch, such as Figure 6-Figure 10 As shown, it includes a housing assembly 100 and an operating mechanism, an energy storage mechanism, a first driving mechanism 400, and a padlock mechanism disposed in the housing assembly 100. The specific structures of the operating mechanism, the energy storage mechanism, and the first driving mechanism 400 are the same as those in Embodiment 1 and will not be described in detail.

[0061] The difference between this embodiment and embodiment 1 is the specific structure of the padlock mechanism. The padlock mechanism includes a second drive mechanism 700, which is provided with a second port 710 for receiving a control signal. The second drive mechanism 700 cooperates with the energy storage mechanism. When the second drive mechanism 700 receives the padlock control signal, it acts so that the energy storage mechanism cannot switch from the energy release opening state to the energy storage closing position, thereby avoiding misoperation after a major fault occurs.

[0062] Specifically, Figure 7 As shown, a swing rod 800 is provided between the second driving mechanism 700 and the rack 320. When the second driving mechanism 700 is actuated, the swing rod 800 cooperates with the rack 320 in the open state, so that the rack 320 cannot move to the closed state, thereby preventing the second operating shaft 310 from rotating to the closed state.

[0063] Specifically, Fig.10As shown, the middle part of the swing lever 800 is provided with a second hinged part 810 hingedly matched with the housing assembly 100, a third pushing part 820 corresponding to the second driving mechanism 700, and a locking part 830 corresponding to the rack 320. A first matching locking groove 321 is provided on one side of the rack 320. When the second driving mechanism 700 receives a padlock control signal to make it act, as shown in FIG. Figure 7 As shown, the second driving mechanism 700 drives the third pushing part 820, and the locking part 830 rotates into the first matching locking groove 321, so that the rack 320 can no longer move left and right, and then the entire energy storage mechanism and operating mechanism cannot perform the closing action, forming a padlock function.

[0064] Specifically, Figure 6 , Figure 7 As shown, the second driving mechanism 700 includes an electromagnetic coil fixing member 720 and an electromagnetic driving block 730 to which an electromagnetic coil is fixed. A second action spring 740 is provided between the electromagnetic coil fixing member 720 and the electromagnetic driving block 730. In this embodiment, the electromagnetic coil fixing member 720 is a shell made of a magnetically conductive material such as low-carbon steel, electrical pure iron, etc., the electromagnetic coil is fixed in the shell, and the electromagnetic driving block 730 is at least partially made of a permanent magnet; there is an adsorption force between the shell made of the magnetically conductive material and the electromagnetic driving block 730, and the adsorption force is greater than The thrust of the second action spring 740 after energy storage ensures that the shell made of magnetic conductive material and the electromagnetic drive block 730 maintain an adsorption relationship in the initial state; when the second drive mechanism 700 receives the padlock control signal, the electromagnetic coil is energized to form a magnetic field and the direction of the magnetic field forms a repulsive force on the electromagnetic drive block 730 away from the electromagnetic coil, and the sum of the repulsive force and the thrust of the second action spring 740 after energy storage is greater than the adsorption force between the shell made of magnetic conductive material and the electromagnetic drive block 730, so that the electromagnetic drive block 730 can be pushed to move.

[0065] A second limiting block 760 is fixed to the front end of the electromagnetic driving block 730 of this embodiment, a limiting groove 761 is formed between the second limiting block 760 and the electromagnetic driving block 730, and the third pushing portion 820 is a folding strip extending into the limiting groove 761, and the two form a linkage.

[0066] Similarly, in this embodiment, a manual reset mechanism is provided for the second driving mechanism 700. Specifically, Figure 6 , Figure 7 As shown, a push rod 750 is provided on the outer side of the second limit block 760 of the second driving mechanism 700, and the push rod 750 passes through the shell assembly 100. By pressing the push rod 750, the second limit block 760 can be reset with the electromagnetic driving block 730 and re-adsorbed with the electromagnetic coil fixing member 720.

[0067] In this embodiment, only the action of the first drive mechanism 400 can realize the energy release of the energy storage mechanism, thereby realizing opening and power off, and the closing of the switch and the energy storage mechanism energy storage reset can be realized by turning the knob. The action of the second drive mechanism 700 cannot realize the energy storage and release, and thus opening and power off. The first drive mechanism 400 and the second drive mechanism 700 must act synchronously or the first drive mechanism 400 and the second drive mechanism 700 must act successively to open the switch and power off, and to padlock. The closing of the switch and the energy storage mechanism energy storage reset cannot be realized by turning the knob, and the second drive mechanism 700 must be manually pushed to reset by the push rod 750 before the closing of the switch and the energy storage mechanism energy storage reset can be realized by turning the knob. When this embodiment is used, the first drive mechanism 400 can be selected to actuate, or the first drive mechanism 400 and the second drive mechanism 700 can be actuated synchronously, or the first drive mechanism 400 can be actuated and the second drive mechanism 700 can be actuated by a remote signal according to the severity of the fault. The first drive mechanism 400 and the second drive mechanism 700 can be actuated automatically by different fault signals, or the first drive mechanism 400 and the second drive mechanism 700 can be actuated by manually sending control signals remotely based on the fault situation.

[0068] Embodiment 3:

[0069] This embodiment provides a rotary isolating switch, such as Figure 11-Figure 12 As shown, it includes a housing assembly 100 and an operating mechanism, an energy storage mechanism, and a first driving mechanism 400 disposed in the housing assembly 100 .

[0070] The operating mechanism and the energy storage mechanism of this embodiment are connected together to form a free tripping structure, including a four-bar operating mechanism and an energy storage mechanism composed of a lock buckle 340, a jump buckle, and an energy storage spring. When the lock buckle 340 and the jump buckle are engaged, the energy storage spring stores energy, and the switch unit is driven to open and close through the action of the four-bar operating mechanism. When the lock buckle 340 and the jump buckle are tripped, the jump buckle and the four-bar operating mechanism form a five-bar mechanism, the energy storage spring releases energy, and the five-bar mechanism quickly acts to complete the tripping and opening. The specific structure is the same as the structure disclosed in the applicant's prior patent CN202310606424.1, and will not be elaborated on in detail.

[0071] A first transmission assembly is provided between the free tripping structure and the knob 900, specifically, comprising a second operating shaft 310 and a rack 320. The second operating shaft 310 is circumferentially linked with the knob 900 and has a gear structure meshing with the rack 320. The rack 320 cooperates with the operating mechanism so that the knob 900, the second operating shaft 310, and the rack 320 sequentially transmit and drive the operating mechanism to perform opening and closing actions.

[0072] The first driving mechanism 400 cooperates with the lock catch 340 to drive the lock catch 340 to rotate to achieve tripping and opening. The first driving mechanism 400 is an electromagnetic driving mechanism, and is provided with a first port 410 for receiving a control signal. The control signal can cause the first driving mechanism 400 to drive the lock catch 340 to operate. Specifically, Fig.12 As shown, a connecting rod 500 is provided between the first driving mechanism 400 and the lock buckle 340. Fig.13 As shown, the connecting rod 500 is provided with a first hinged portion 510 for being hingedly connected to the housing assembly 100, a first pushing portion 520 arranged corresponding to the first driving mechanism 400, and a driving portion 530 arranged corresponding to the lock buckle 340. The action of the first driving mechanism 400 is transmitted through the connecting rod 500 to drive the lock buckle 340 to disengage from the jump buckle.

[0073] When the knob 900 is turned to close the switch, the free tripping structure can complete the locking buckle 340, the tripping buckle and the energy storage spring completes the energy storage. At the same time, the second operating shaft 310 is provided with a reset transmission block 311 that cooperates with the first driving mechanism 400. By rotating the second operating shaft 310, the reset transmission block 311 can drive the driving rod of the first driving mechanism 400 to complete the magnetic adsorption reset.

[0074] After a fault occurs, a control signal is sent to the first drive mechanism 400, causing the lock catch 340 and the trip catch to trip, and the energy storage spring to release energy, thereby quickly opening the circuit breaker and shutting off the power. After the fault is eliminated, by rotating the second operating shaft 310, the lock catch 340 and the trip catch can be re-fastened, the energy storage spring can be charged, and the first drive mechanism 400 can be reset.

[0075] In this embodiment, on the basis of the above structure, a padlock mechanism is added in the housing assembly 100, through which the switch cannot be locked or closed again, thereby avoiding misoperation. When the fault is not eliminated and solved, the switch is closed and energized. Specifically, the padlock mechanism includes a second drive mechanism 700, which is provided with a second port 710 for receiving a control signal. The second drive mechanism 700 cooperates with a free tripping structure. When the second drive mechanism 700 receives a padlock control signal, it acts to make the free tripping structure unable to be locked or closed again, thereby avoiding misoperation after a major fault occurs.

[0076] Specifically, the second driving mechanism 700 is arranged on the outside of the first driving mechanism 400, and the connecting rod 500 extends outward from the first pushing portion 520 to form a second pushing portion 540 corresponding to the second driving mechanism 700. When the second driving mechanism 700 is actuated, the second pushing portion 540 is supported, so that the connecting rod 500 cannot rotate. The lock buckle 340 and the trip buckle need to be rotated to complete the re-locking. The lock buckle 340 cannot be rotated under the action of the connecting rod 500, thereby making it impossible for the lock buckle 340 and the trip buckle to complete the re-locking, and the switch unit cannot be closed.

[0077] The second driving mechanism 700 includes an electromagnetic coil fixing member 720 and an electromagnetic driving block 730 to which an electromagnetic coil is fixed. A second action spring 740 is arranged between the electromagnetic coil fixing member 720 and the electromagnetic driving block 730. In this embodiment, the electromagnetic coil fixing member 720 is a shell made of a magnetically conductive material such as low carbon steel, electrical pure iron, etc., the electromagnetic coil is fixed in the shell, and the electromagnetic driving block 730 is at least partially made of a permanent magnet; there is an adsorption force between the shell made of the magnetically conductive material and the electromagnetic driving block 730, and the adsorption force is greater than the thrust of the second action spring 740 after energy storage, ensuring that the shell made of the magnetically conductive material and the electromagnetic driving block 730 maintain an adsorption relationship in the initial state; when the second driving mechanism 700 receives a padlock control signal, the electromagnetic coil is energized to form a magnetic field and the direction of the magnetic field forms a repulsive force on the electromagnetic driving block 730 away from the electromagnetic coil, and the sum of the repulsive force and the thrust of the second action spring 740 after energy storage is greater than the adsorption force between the shell made of the magnetically conductive material and the electromagnetic driving block 730, so that the electromagnetic driving block 730 can be pushed to move.

[0078] Furthermore, in this embodiment, a manual reset mechanism is provided for the second driving mechanism 700, specifically, Fig.11 , Fig.12 As shown, a push rod 750 is provided on the outside of the electromagnetic driving block 730 of the second driving mechanism 700, and a driving through hole 110 is provided on the shell assembly 100 corresponding to the push rod 750. The push rod 750 can be pressed through the driving through hole 110 to reset the electromagnetic driving block 730 and re-adsorb it onto the electromagnetic coil fixing member 720.

[0079] In this embodiment, the first drive mechanism 400 and the second drive mechanism 700 can both achieve the lock 340, tripping and tripping, and complete the tripping and opening. Only the first drive mechanism 400 is in motion, and the knob can be turned to achieve re-locking, closing and energy storage reset of the energy storage mechanism. Only the second drive mechanism 700 is in motion, and the knob cannot be turned to achieve re-locking, closing and energy storage reset of the energy storage mechanism. The second drive mechanism 700 must be manually pushed to reset by the push rod 750 before the knob can be turned to achieve re-locking, closing and energy storage reset of the energy storage mechanism. When this embodiment is used, the first drive mechanism 400 or the second drive mechanism 700 can be selected to act according to the severity of the fault, or the first drive mechanism 400 and the second drive mechanism 700 can be synchronously acted, or the first drive mechanism 400 and the second drive mechanism 700 can be acted by remote signals. The first drive mechanism 400 and / or the second drive mechanism 700 can be automatically acted by different fault signals, or the first drive mechanism 400 and / or the second drive mechanism 700 can be manually remotely sent based on the fault situation to respectively act the first drive mechanism 400 and / or the second drive mechanism 700.

[0080] Embodiment 4:

[0081] This embodiment provides a rotary isolating switch, such as Figure 14-16 As shown, it includes a housing assembly 100 and an operating mechanism, an energy storage mechanism, a first driving mechanism 400, a padlock mechanism, and a knob 900 disposed in the housing assembly 100. The specific structures of the housing assembly 100, the operating mechanism, and the energy storage mechanism are the same as those in Embodiment 3 and are not described in detail.

[0082] A first transmission assembly is provided between the free tripping structure and the knob 900, specifically, comprising a second operating shaft 310 and a rack 320. The second operating shaft 310 is circumferentially linked with the knob 900 and has a gear structure meshing with the rack 320. The rack 320 cooperates with the operating mechanism so that the knob 900, the second operating shaft 310, and the rack 320 sequentially transmit and drive the operating mechanism to perform opening and closing actions.

[0083] When the knob 900 is turned to close the switch, the free tripping structure can complete the locking buckle 340, the tripping buckle and the energy storage spring completes the energy storage. At the same time, the second operating shaft 310 is provided with a reset transmission block 311 that cooperates with the first driving mechanism 400. When the second operating shaft 310 is turned, the reset transmission block 311 drives the driving rod of the first driving mechanism 400 to complete the magnetic adsorption reset.

[0084] The difference between this embodiment and embodiment 3 is the specific structure of the padlock mechanism. The padlock mechanism includes a second drive mechanism 700, which is provided with a second port 710 for receiving a control signal. The second drive mechanism 700 cooperates with the first transmission component. When the second drive mechanism 700 receives the padlock control signal, it acts to prevent the first transmission component from acting, thereby avoiding misoperation after a major failure.

[0085] Specifically, Fig.15 , Fig.16 As shown, a first limit block 312 is disposed at the upper end of the second operating shaft 310 , and the position of the second driving mechanism 700 is disposed corresponding to the first limit block 312 of the second operating shaft 310 .

[0086] Specifically, the second driving mechanism 700 includes an electromagnetic coil fixing member 720 and an electromagnetic driving block 730 to which an electromagnetic coil is fixed. A second action spring 740 is provided between the electromagnetic coil fixing member 720 and the electromagnetic driving block 730. In this embodiment, the electromagnetic coil fixing member 720 is a shell made of a magnetically conductive material such as low-carbon steel, electrical pure iron, etc., the electromagnetic coil is fixed in the shell, and the electromagnetic driving block 730 is at least partially made of a permanent magnet; there is an adsorption force between the shell made of the magnetically conductive material and the electromagnetic driving block 730, and the adsorption force The thrust of the second action spring 740 after energy storage is greater than that of the second action spring 740, ensuring that the shell made of magnetic conductive material and the electromagnetic drive block 730 maintain an adsorption relationship in the initial state; when the second drive mechanism 700 receives the padlock control signal, the electromagnetic coil is energized to form a magnetic field and the direction of the magnetic field forms a repulsive force on the electromagnetic drive block 730 away from the electromagnetic coil, and the sum of the repulsive force and the thrust of the second action spring 740 after energy storage is greater than the adsorption force between the shell made of magnetic conductive material and the electromagnetic drive block 730, so that the electromagnetic drive block 730 can be pushed to move.

[0087] The electromagnetic coil fixing part 720 is limited in the housing assembly 100, and the front end of the electromagnetic driving block 730 is linked with a blocking part 770. When the second driving mechanism 700 is not in operation, the blocking part 770 avoids the moving trajectory of the first limiting block 312, so that the second operating shaft 310 can rotate normally for opening and closing. When the second driving mechanism 700 is in operation, the blocking part 770 moves to the moving trajectory of the first limiting block 312, forming a block for the first limiting block 312, so that the second operating shaft 310 located in the closing position cannot be rotated to the opening position, so that the lock buckle 340 and the jump buckle can no longer be buckled to close the switch.

[0088] Furthermore, in this embodiment, a manual reset mechanism is provided for the second driving mechanism 700, specifically, Fig.15 , Fig.16 As shown, a push rod 750 is provided on the outside of the electromagnetic driving block 730 of the second driving mechanism 700, and a driving through hole 110 is provided on the shell assembly 100 corresponding to the push rod 750. The push rod 750 can be pressed through the driving through hole 110 to reset the electromagnetic driving block 730 and re-adsorb it onto the electromagnetic coil fixing member 720.

[0089] In this embodiment, only the action of the first drive mechanism 400 can realize the energy release of the energy storage mechanism, thereby realizing opening and power off, and the re-engagement, closing and energy storage reset of the energy storage mechanism can be realized by turning the knob. The action of the second drive mechanism 700 cannot realize the energy storage and release, and thus opening and power off. The first drive mechanism 400 and the second drive mechanism 700 must act synchronously or the first drive mechanism 400 and the second drive mechanism 700 must act successively to open and power off, and the padlock cannot be locked by turning the knob to realize re-engagement, closing and energy storage reset of the energy storage mechanism. The second drive mechanism 700 must be manually pushed to reset by the push rod 750 before re-engagement, closing and energy storage reset of the energy storage mechanism can be realized by turning the knob. When this embodiment is used, the first drive mechanism 400 can be selected to actuate, or the first drive mechanism 400 and the second drive mechanism 700 can be actuated synchronously, or the first drive mechanism 400 can be actuated and the second drive mechanism 700 can be actuated by a remote signal according to the severity of the fault. The first drive mechanism 400 and the second drive mechanism 700 can be actuated automatically by different fault signals, or the first drive mechanism 400 and the second drive mechanism 700 can be actuated by manually sending control signals remotely based on the fault situation.

[0090] Embodiment 5:

[0091] This embodiment provides a rotary isolating switch, such as Figure 17-Figure 18 As shown, it includes a housing assembly 100 and an operating mechanism, an energy storage mechanism, and a first driving mechanism 400 disposed in the housing assembly 100 .

[0092] The structure of this embodiment is substantially the same as that of the embodiment 3, with the main difference being that the second driving mechanism 700 of this embodiment is disposed at the upper end of the first driving mechanism 400, and the connecting rod 500 is bent upward and extended at the first pushing portion 520 to form a second pushing portion 540 corresponding to the second driving mechanism 700. When the second driving mechanism 700 is actuated, the second pushing portion 540 is supported, so that the connecting rod 500 cannot rotate. The lock buckle 340 and the trip buckle need to be rotated to complete the re-locking. The lock buckle 340 cannot be rotated under the action of the connecting rod 500, thereby making it impossible for the lock buckle 340 and the trip buckle to complete the re-locking, and the switch unit cannot be closed.

[0093] The first driving mechanism 400 and the second driving mechanism 700 are both electromagnetic driving mechanisms. In order to avoid interference between the electromagnetic fields therebetween, a magnetic isolation plate 780 is provided between the first driving mechanism 400 and the second driving mechanism 700. The magnetic isolation plate 780 not only fixes the first driving mechanism 400 and the second driving mechanism 700, but also prevents the electromagnetic fields therebetween from causing interference.

[0094] Similar to Example 3, in this embodiment, the action of the first drive mechanism 400 and the action of the second drive mechanism 700 can both realize the lock 340 and the tripping release, and complete the tripping and opening of the switch. Only the first drive mechanism 400 is actuated, and the re-locking, closing and energy storage mechanism energy storage reset can be achieved by turning the knob. Only the second drive mechanism 700 is actuated, and the re-locking, closing and energy storage mechanism energy storage reset cannot be achieved by turning the knob. The second drive mechanism 700 must be manually pushed to reset by the push rod 750 before the re-locking, closing and energy storage mechanism energy storage reset can be achieved by turning the knob. When this embodiment is used, the first drive mechanism 400 or the second drive mechanism 700 can be selected to act according to the severity of the fault, or the first drive mechanism 400 and the second drive mechanism 700 can act synchronously, or the first drive mechanism 400 can act and the second drive mechanism 700 can be controlled to act through a remote signal. The first drive mechanism 400 and / or the second drive mechanism 700 can be automatically acted through different fault signals, or the first drive mechanism 400 and / or the second drive mechanism 700 can be acted by manually sending remote control signals based on the fault situation.
