Therefore, it cannot be understood as a limitation on the present invention.
[0035] In addition, the terms "first", "second", etc., if used, are merely used to distinguish and describe, and should not be understood as indicating or implying relative importance.
[0036] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention can be combined with each other.
[0037] Please refer to Figure 1-Figure 3In the embodiment of the present application, a disconnector mechanism 10 that is held in place is provided, and in the embodiment, a disconnector that is operated using the above-mentioned isolation structure is also provided. The disconnector mechanism 10 that is held in place and the disconnector can be applied to a circuit to realize the on / off and grounding control of the circuit. In other words, the disconnector mechanism 10 that is held in place and the disconnector can realize operations such as closing, opening and grounding, thereby realizing the conduction, disconnection and grounding of the circuit. The disconnector mechanism 10 that is held in place can be used to operate the disconnector so that the disconnector performs closing, opening and grounding. It is worth noting that the disconnector mechanism 10 that is held in place and the disconnector provided in the present embodiment can improve the problems of poor circuit stability and low safety in the prior art.
[0038] It should be noted that the problem of poor circuit stability and low safety in the prior art is mainly due to the loosening of components in the operating mechanism after multiple operations in the existing structure, which in turn causes the components to not be in place after operation, resulting in problems such as inadequate closing and grounding, resulting in poor circuit stability and reduced safety. Based on this, in order to solve the above problems, the isolating switch mechanism 10 and isolating switch with a fixed abutment in this embodiment are provided.
[0039] In this embodiment, the isolating switch mechanism 10 with in-place abutment includes a carrier 100, an output shaft 200, a transition rotating member 700, a positioning member 210, and a first positioning member 300. The output shaft 200 is rotatably connected to the carrier 100 and is configured to rotate relative to the carrier 100 to achieve closing, opening, or grounding. In other words, when the output shaft 200 rotates, closing, opening, and grounding can be achieved when the output shaft 200 rotates to different positions. It is worth noting that the isolating switch mechanism 10 with in-place abutment may also include components such as an operating mechanism to achieve the functions of the isolating switch mechanism 10 with in-place abutment. Furthermore, the positioning member 210 is fixedly mounted on the transition rotating member 700 to rotate with the transition rotating member 700. In other words, when the output shaft 200 rotates to achieve closing, opening, or grounding, the output shaft 200 drives the transition rotating member 700 to rotate, and synchronously, the transition rotating member 700 drives the positioning member 210 to rotate. The first positioning member 300 is disposed on the carrier 100 and on the rotation path of the positioning member 210 ; the positioning member 210 is used to abut against the first positioning member 300 when the output shaft 200 rotates to close or ground.
[0040] As described above, when the isolating switch mechanism 10 with abutment in place performs a closing operation or a grounding operation, the positioning member 210 abuts against the first positioning member 300 to determine whether the closing operation or the grounding operation is in place, which can facilitate the operator to determine whether the closing operation or the grounding operation is in place. Moreover, it is precisely because of the positional stability of the first positioning member 300 that the stability of the cooperating position of the positioning member 210 and the first positioning member 300 can be ensured, which can ensure the stability of the cooperating position of the closing operation or the grounding operation, thereby effectively achieving the closing operation or the grounding operation, avoiding the problem of inadequate closing or inadequate grounding, and improving the circuit stability and thus the safety of the circuit. Based on this, the isolating switch mechanism 10 with abutment in place provided in this embodiment can improve the problem of low circuit stability and reduced safety in the prior art.
[0041] It should be noted that in this embodiment, the first positioning member 300 can be disposed in the rotational path of the positioning member 210 when the output shaft 200 rotates for closing, and is used to abut against the positioning member 210 when closing is complete, thereby completing the closing position. Alternatively, the first positioning member 300 can also be disposed in the rotational path of the positioning member 210 when the output shaft 200 rotates for grounding, and is used to abut against the positioning member 210 when grounding is complete, thereby completing the grounding position.
[0042] In other words, when the first positioning member 300 is provided, the positioning function of one of closing and grounding can be achieved, ensuring that one of the functions can be stably executed, thereby improving the stability of the circuit and further improving the circuit safety.
[0043] Optionally, an eccentric first rotating shaft 310 is provided on the first positioning member 300, and the first rotating shaft 310 is rotatably connected to the carrier 100. Even if the first positioning member 300 or the positioning member 210 is misaligned, the eccentric rotation of the first positioning member 300 can be used to adjust the position of the first positioning member 300 on the carrier 100, thereby adjusting the first positioning member 300 to a position where it cooperates with the positioning member 210 to achieve the closed position or the grounded position, thereby avoiding the problem of incomplete closed position or incomplete grounding, thereby achieving the purpose of improving circuit stability and circuit safety.
[0044] It should be noted that since the first rotating shaft 310 is eccentrically arranged relative to the first positioning member 300, the first positioning member 300 will move in the radial direction during the rotation process around the first rotating shaft 310, so that the position when it is in contact with the positioning member 210 can be adjusted. The position of the first positioning member 300 can be adjusted based on actual conditions to facilitate adjusting the first positioning member 300 to a suitable position, so that the first positioning member 300 is in the closed position or grounded position when it is in contact with the positioning member 210.
[0045] Optionally, in this embodiment, a first groove 211 is provided on one side of the positioning member 210. When the positioning member 210 abuts against the first positioning member 300, the first positioning member 300 is accommodated in the first groove 211. Accommodating the first positioning member 300 in the first groove 211 can increase the contact area between the first positioning member 300 and the positioning member 210, thereby improving the abutment stability of the first positioning member 300 and the positioning member 210, ensuring the relative position stability of the first positioning member 300 and the positioning member 210 after the circuit breaker is fully closed or grounded, thereby ensuring the stability of the circuit in the closed state or grounded state, thereby improving the stability and safety of the circuit.
[0046] Furthermore, the opening width of the first groove 211 is greater than the diameter of the first positioning member 300. It is worth noting that after the first positioning member 300 rotates about the first rotation axis 310, the position of the first positioning member 300 may change. In this case, the position of the first positioning member 300 in the first groove 211 will also change. Setting the opening width of the first groove 211 to be greater than the diameter of the first positioning member 300 ensures that after the position of the first positioning member 300 is adjusted, the first positioning member 300 can still be accommodated in the first groove 211 when the circuit breaker is in the closed position or the grounding position, thereby facilitating the mutual cooperation between the first positioning member 300 and the positioning member 210.
[0047] Furthermore, in this embodiment, the in-position abutment disconnector mechanism 10 further includes a second positioning member 400, which is disposed on the carrier 100 and located in the rotational path of the positioning member 210, with the first positioning member 300 and the second positioning member 400 spaced apart. The positioning member 210 is configured to abut against the first positioning member 300 and the second positioning member 400 when the output shaft 200 rotates to the closing and grounding positions, respectively. In other words, by simultaneously providing the first positioning member 300 and the second positioning member 400 to respectively perform the closing and grounding positioning, the in-position abutment disconnector mechanism 10 can achieve precise positioning regardless of whether it is performing the closing or grounding function, ensuring precise closing and grounding, and effectively improving the stability and safety of the overall circuit.
[0048] It should be noted that if the first positioning member 300 is arranged on the rotation path of the positioning member 210 when it rotates to close the switch to provide a positioning function for closing the switch in place, the second positioning member 400 is arranged on the rotation path of the positioning member 210 when it rotates to ground to provide a positioning function for grounding in place; correspondingly, if the first positioning member 300 is arranged on the rotation path of the positioning member 210 when it rotates to ground to provide a positioning function for grounding in place, the second positioning member 400 is arranged on the rotation path of the positioning member 210 when it rotates to close the switch to provide a positioning function for closing the switch in place.
[0049] Optionally, the second positioning member 400 is provided with an eccentric second rotating shaft 410, which is rotatably connected to the carrier 100. Similar to the first positioning member 300, even if the second positioning member 400 or the positioning member 210 is misaligned, the eccentric rotation of the second positioning member 400 can be used to adjust the position of the second positioning member 400 on the carrier 100, thereby adjusting the second positioning member 400 to a position where it cooperates with the positioning member 210 to achieve the closed position or the grounded position, thereby avoiding the problem of incomplete closing or incomplete grounding, and achieving the purpose of improving circuit stability and circuit safety.
[0050] Similarly, since the second rotating shaft 410 is eccentrically arranged relative to the second positioning member 400, the second positioning member 400 will move in the radial direction during the rotation of the second rotating shaft 410 as the axis, and the position when it abuts against the positioning member 210 can be adjusted. The position of the second positioning member 400 can be adjusted based on actual conditions to facilitate adjusting the second positioning member 400 to a suitable position, so that the second positioning member 400 is in the closed position or grounded position when it abuts against the positioning member 210.
[0051] In this embodiment, the positioning member 210 is provided with a second groove 212. When the positioning member 210 abuts against the second positioning member 400, the second positioning member 400 is accommodated in the second groove 212. Accommodating the second positioning member 400 in the second groove 212 can increase the contact area between the second positioning member 400 and the positioning member 210, thereby improving the abutment stability between the second positioning member 400 and the positioning member 210, ensuring the relative position stability of the second positioning member 400 and the positioning member 210 after the circuit breaker is in the closed position or grounded position, thereby ensuring the stability of the circuit in the closed state or grounded state, thereby improving the stability and safety of the circuit.
[0052] Optionally, the opening width of the second groove 212 is greater than the diameter of the second positioning member 400. It is worth noting that after the second positioning member 400 rotates about the second rotation axis 410, the position of the second positioning member 400 may change. At this time, the position of the second positioning member 400 corresponding to the second groove 212 will also change. Setting the opening width of the second groove 212 to be greater than the diameter of the second positioning member 400 can ensure that after the position of the second positioning member 400 is adjusted, the second positioning member 400 can still be accommodated in the second groove 212 when the switch is in the closed position or the grounded position, thereby facilitating the mutual cooperation between the second positioning member 400 and the positioning member 210.
[0053] It should be understood that in other embodiments of the present application, one or both of the first groove 211 and the second groove 212 may be eliminated.
[0054] In this embodiment, the isolating switch mechanism 10 for holding in place further includes a closing operating shaft 500 and a grounding operating shaft 600. Both the closing operating shaft 500 and the grounding operating shaft 600 are rotatably mounted on the carrier 100, and the closing operating shaft 500 and the grounding operating shaft 600 are spaced apart. The closing operating shaft 500 is connected to the output shaft 200 via a gear structure; the grounding operating shaft 600 is connected to the output shaft 200 via a gear structure; and a transition rotating member 700 is sleeved on the closing operating shaft and can rotate freely relative to the closing operating shaft 500. That is, when the closing operating shaft 500 is rotated under force, the output shaft 200 and the transition rotating member 700 are simultaneously driven to rotate. Correspondingly, when the grounding operating shaft 600 is rotated under force, the transition rotating member 700 and the output shaft 200 are also simultaneously driven to rotate. In this case, the rotation of the transition rotating member 700 is not affected by the closing operating shaft 500.
[0055] When performing a closing operation, the operator can rotate the closing operating shaft 500 to transmit power to the output shaft 200, thereby performing the closing function. Correspondingly, when performing a grounding operation, the operator can rotate the grounding operating shaft 600 to transmit power to the output shaft 200, thereby performing the grounding function.
[0056] The isolating switch provided in this embodiment adopts the above-mentioned isolating switch mechanism 10 with abutment in place. Therefore, the isolating switch can achieve the purpose of improving the problem of low circuit stability and reduced safety in the prior art. The overall structure of the isolating switch can refer to the above-mentioned isolating switch mechanism 10 with abutment in place, and will not be repeated here.
[0057] In summary, in the isolating switch mechanism 10 and isolating switch provided in this embodiment, the positioning member 210 is abutted against the first positioning member 300 to determine whether the closing operation or the grounding operation is in place, which can facilitate the operator to determine whether the closing operation and the grounding operation are in place. Moreover, it is precisely because of the positional stability of the first positioning member 300 that the positioning member 210 and the first positioning member 300 can ensure the stability of the matching position, which can ensure the stability of the matching position of the closing operation or the grounding operation, thereby effectively achieving the closing operation or the grounding operation, avoiding the problem of inadequate closing or inadequate grounding, and improving the circuit stability and thus the safety of the circuit. Based on this, the isolating switch mechanism 10 provided in this embodiment can improve the problem of low circuit stability leading to reduced safety in the prior art. Similarly, when the second positioning member 400 is provided, the first positioning member 300 and the second positioning member 400 can respectively achieve the positioning of the closing operation and the positioning of the grounding operation, ensuring the precise closing function and the grounding function, and ensuring the overall stability and safety of the circuit. Furthermore, through the setting of the first rotating shaft 310 and the second rotating shaft 410, in the event of positional deviation of the positioning member 210, the first positioning member 300 or the second positioning member 400, the position of the first positioning member 300 can be adjusted based on the setting of the first rotating shaft 310, and the setting of the second positioning member 400 can be adjusted based on the setting of the second rotating shaft 410, thereby ensuring the positioning accuracy of the closing position and the positioning accuracy of the grounding position.
[0058] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
