Therefore, the directions and positions used are used to explain and understand the present invention, but not to limit the scope of protection of the present invention.
[0040] Embodiment 1:
[0041] This embodiment provides a rotary isolating switch, such as Figure 1-Figure 2 As shown, it includes a housing assembly 100 and a free tripping structure 300 , a first driving mechanism 400 , and a second driving mechanism 700 disposed in the housing assembly 100 .
[0042] The free tripping structure includes a four-bar operating mechanism, an energy storage spring, a lock 310, and a tripping buckle. When the lock 310 and the tripping 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 310 and the tripping buckle are tripped, the tripping 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.
[0043] A first transmission assembly is provided between the free tripping structure and the knob 800, specifically, as Figure 3 As shown, it includes an operating shaft 200 and a rack 220. The operating shaft 200 is circumferentially linked with the knob 800 and has a gear structure meshing with the rack 220. The rack 220 cooperates with the four-bar operating mechanism, so that the knob 800, the operating shaft 200, and the rack 220 are sequentially driven to drive the four-bar operating mechanism to perform opening and closing actions.
[0044] The first driving mechanism 400 cooperates with the lock buckle 310 to drive the lock buckle 310 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 drive the first driving mechanism 400 to drive the lock buckle 310 to operate.
[0045] Specifically, the first driving mechanism 400 includes an electromagnetic coil fixing part and an electromagnetic driving block to which an electromagnetic coil is fixed, a first action spring 420 is arranged between the electromagnetic coil fixing part and the electromagnetic driving block, the electromagnetic coil fixing part is at least partially made of a magnetically conductive material, and the electromagnetic driving block is at least partially made of a permanent magnet; there is an adsorption force between the electromagnetic coil fixing part and the electromagnetic driving block, and the adsorption force is greater than the thrust of the first action spring 420 after energy storage; when the first driving mechanism 400 is energized, the electromagnetic coil is energized to form a repulsive force on the electromagnetic driving block away from the electromagnetic coil, and the sum of the repulsive force and the thrust of the first action spring 420 after energy storage is greater than the adsorption force between the electromagnetic coil fixing part and the electromagnetic driving block. A connecting rod 500 is arranged between the electromagnetic driving block of the first driving mechanism 400 and the lock buckle 310, such as Figure 5 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 an action portion 530 arranged corresponding to the lock 310. When the electromagnetic coil of the first driving mechanism 400 is energized, the electromagnetic driving block is actuated to drive the lock 310 to disengage from the jump buckle through the connecting rod 500.
[0046] When the lock catch 310 and the trip catch are released, the knob 800 is in the closing position. When the knob 800 is rotated to the opening position, the free tripping structure can complete the lock catch 310 and the trip catch again, and the energy storage spring completes energy storage. At the same time, the operating shaft 200 is provided with a reset transmission block 210 that cooperates with the first drive mechanism 400. By rotating the operating shaft 200, the reset transmission block 210 can drive the drive rod of the first drive mechanism 400 to complete the magnetic adsorption reset.
[0047] After a fault occurs, a control signal is sent to the first drive mechanism 400, causing the lock catch 310 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 operating shaft 200, the lock catch 310 and the trip catch can be re-locked, the energy storage spring can be stored, and the first drive mechanism 400 can be reset, and then the circuit breaker can be opened and closed normally.
[0048] On the basis of the above structure, this embodiment adds a padlock mechanism in the housing assembly 100, through which the switch can no longer be locked and closed, avoiding misoperation. When the fault is not eliminated and resolved, 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 free tripping structure. When the second drive mechanism 700 receives the padlock control signal, it acts so that the free tripping structure cannot switch from the tripping state to the re-locking state, thereby failing to complete the closing of the switch, avoiding misoperation after a major fault occurs.
[0049] 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 310 and the trip buckle need to be rotated to complete the re-locking. The lock buckle 310 cannot be rotated under the action of the connecting rod 500, thereby making it impossible for the lock buckle 310 and the trip buckle to complete the re-locking, and the switch unit cannot be closed.
[0050] The second driving mechanism 700 includes an electromagnetic coil fixing part and an electromagnetic driving block to which an electromagnetic coil is fixed, and a second action spring 720 is arranged between the electromagnetic coil fixing part and the electromagnetic driving block. In this embodiment, the electromagnetic coil fixing part 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 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, and the adsorption force is greater than the thrust of the second action spring 720 after energy storage, ensuring that the shell made of the magnetically conductive material and the electromagnetic driving block 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 away from the electromagnetic coil, and the sum of the repulsive force and the thrust of the second action spring 720 after energy storage is greater than the adsorption force between the shell made of the magnetically conductive material and the electromagnetic driving block, so that the electromagnetic driving block can be pushed to move.
[0051] Furthermore, in this embodiment, a manual reset mechanism is provided for the second driving mechanism 700, specifically, Figure 3 As shown, a push rod 750 is provided on the outside of the electromagnetic driving block 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 and re-adsorb it onto the electromagnetic coil fixing part.
[0052] Specifically, the housing assembly 100 includes a transmission box composed of a lower housing member 120 and an upper housing member 130 , the first driving mechanism 400 and the second driving mechanism 700 are both disposed in the transmission box, and the push rod 750 is limited between the lower housing member 120 and the upper housing member 130 .
[0053] 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 310 and the tripping release, and complete the tripping and opening. 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.
[0054] The knob 800 has a central rotation axis, and the first driving mechanism 400 and the second driving mechanism 700 are sequentially arranged in a direction perpendicular to the central rotation axis. The lower housing 120 is provided with a first limiting frame 121 and a second limiting frame 122 for limiting the first driving mechanism 400 and the second driving mechanism 700, respectively, and the first driving mechanism 400 and the second driving mechanism 700 are arranged at a certain distance.
[0055] Embodiment 2:
[0056] 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, and a first driving mechanism 400 disposed in the housing assembly 100 .
[0057] The structure of this embodiment is roughly the same as that of the embodiment 1, and the main difference is that the second driving mechanism 700 of this embodiment is arranged at the upper end of the first driving mechanism 400, and at the same time, the connecting rod 500 is bent upward at the first pushing portion 520 to extend to form a second pushing portion 540 corresponding to the second driving mechanism 700, that is, the first driving mechanism 400 and the second driving mechanism 700 are arranged in sequence in the direction of the central rotation axis. Specifically, the housing assembly 100 includes a transmission box composed of a lower housing member 120 and an upper housing member 130, and the first driving mechanism 400 and the second driving mechanism 700 are both arranged in the transmission box. The lower housing member 120 is provided with a first limiting frame 121 for limiting the first driving mechanism 400, and the first driving mechanism 400 and the second driving mechanism 700 are matched through a magnetic isolation limiting pad 600. When the second driving mechanism 700 is in operation, it presses against the second pushing portion 540, so that the connecting rod 500 cannot rotate. The lock buckle 310 and the trip buckle need to be rotated to complete the re-locking. The lock buckle 310 cannot rotate under the action of the connecting rod 500, thereby making it impossible for the lock buckle 310 and the trip buckle to complete the re-locking, and the switch unit cannot be closed.
[0058] The first drive mechanism 400 and the second drive mechanism 700 are both electromagnetic drive mechanisms. In order to avoid interference between the electromagnetic fields therebetween, a magnetic isolation limiting pad 600 is provided between the first drive mechanism 400 and the second drive mechanism 700. The magnetic isolation limiting pad 600 not only fixes the first drive mechanism 400 and the second drive mechanism 700, but also prevents the electromagnetic fields therebetween from interfering with each other. The third limiting frame 610 and the fourth limiting frame 620 are provided on the upper and lower sides of the magnetic isolation limiting pad 600 for the first drive mechanism 400 and the second drive mechanism 700, respectively, to form a limiting cooperation effect. Similar to Example 1, 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 310 and the tripping release, and complete the tripping and opening. 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.

[0060] The above disclosure is only a preferred embodiment of the present invention, and certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the claims of the present invention are still within the scope covered by the present invention.
