[0033] Please refer to Figure 1In one aspect of an embodiment of the present application, an operating mechanism 100 is provided, including a driving assembly 110 and a main circuit energy storage unit 120 and a pre-charging circuit energy storage unit 130 respectively connected to the driving assembly 110 by transmission; the driving assembly 110 includes a rotating shaft 111 and a main circuit driving gear 114 and a pre-charging driving gear 113 respectively arranged on the rotating shaft 111, the rotating shaft 111 is driven to rotate by a preset angle, the main circuit driving gear 114 rotates by a first angle and drives the main circuit energy storage unit 120 to rotate and store energy, and the pre-charging driving gear 113 rotates by a second angle and drives the pre-charging circuit energy storage unit 130 to rotate and store energy; when the main circuit energy storage unit 120 rotates to a preset position, it can release energy and drive the main circuit switch body 210 of the fusion switch 200 to close; when the pre-charging circuit energy storage unit 130 rotates to a preset position, it can release energy and drive the pre-charging circuit switch body 220 of the fusion switch 200 to close;

[0034] The second angle is greater than the first angle, so that the pre-charging circuit energy storage unit 130 rotates to a preset position before the main circuit energy storage unit 120 .

[0035] Specifically, the present application provides an operating mechanism 100, which is used to control the opening and closing of a fusion switch 200; the fusion switch 200 includes a pre-charging circuit switch body 220 and a main circuit switch body 210, and the operating mechanism 100 can be connected to the pre-charging circuit switch body 220 and the main circuit switch body 210 respectively to drive the opening or closing of the pre-charging circuit switch body 220 and the main circuit switch body 210.

[0036] Among them, Figure 1 and Figure 2 As shown, the operating mechanism 100 includes a housing and a driving assembly 110 disposed in the housing, a main circuit energy storage unit 120 and a pre-charging circuit energy storage unit 130 respectively connected to the driving assembly 110 by transmission.

[0037] It should be noted that, in one possible implementation of the present application, the driving assembly 110 includes a rotating shaft 111 and a main circuit driving gear 114 and a pre-filling driving gear 113 respectively disposed on the rotating shaft 111, and the main circuit driving gear 114 and the pre-filling driving gear 113 have a preset radius ratio and a setting position;

[0038] The rotating shaft 111 can be electrically or manually controlled to drive the main circuit drive gear 114 and the pre-charging drive gear 113 to rotate. The pre-charging drive gear 113 can be driven and matched with the pre-charging circuit energy storage unit 130 to achieve the closing of the pre-charging circuit switch body 220, and the main circuit drive gear 114 can be driven and matched with the main circuit energy storage unit 120 to achieve the closing of the main circuit switch body 210.

[0039] The existing operating mechanism usually includes a main circuit shaft gear and a pre-charging shaft gear of the transmission setting. The main circuit shaft gear can drive the pre-charging shaft gear to rotate, thereby respectively realizing the closing of the main circuit switch body and the pre-charging circuit switch body. This setting method makes the rotation angle of the main circuit shaft gear and the pre-charging shaft gear fixed, resulting in the position layout between the main circuit switch body and the pre-charging circuit switch body and the operating mechanism tending to be fixed, reducing the flexibility of the internal layout of the fusion switch and the space utilization rate.

[0040] In this regard, the present application arranges the main circuit drive gear 114 and the pre-filling drive gear 113 coaxially on the rotating shaft 111 so that the main circuit rotating shaft gear 112 no longer directly drives the pre-filling rotating shaft gear 115 to rotate, and the rotation of the main circuit rotating shaft gear 112 and the pre-filling rotating shaft gear 115 are independent of each other. The rotation angle corresponding to the main circuit rotating shaft gear 112 and the pre-filling rotating shaft gear 115 can be calculated according to the transmission ratio required when the main circuit switch body 210 and the pre-filling circuit switch body 220 are closed, and the main circuit drive gear 114 and the pre-filling drive gear 113 are correspondingly calculated and adjusted according to the rotation angle to have a preset radius ratio or number of teeth, so as to ensure that the operating mechanism 100 can realize the closing of the main circuit switch body 210 and the pre-filling circuit switch body 220 of the fusion switch 200.

[0041] The rotating shaft 111 can be electrically or manually controlled to drive the main circuit driving gear 114 and the pre-charging driving gear 113 to rotate, and respectively drive the main circuit energy storage unit 120 and the pre-charging circuit energy storage unit 130 to rotate and store energy; the main circuit energy storage unit 120 and the pre-charging circuit energy storage unit 130 are respectively connected to the pre-charging circuit switch body 220 and the main circuit switch body 210 on the side away from the driving assembly 110. When the main circuit energy storage unit 120 and the pre-charging circuit energy storage unit 130 rotate to a preset position, they can release energy and drive the pre-charging circuit switch body 220 to close first and the main circuit switch body 210 to close later.

[0042] The driving rotating shaft 111 rotates a preset angle, the main circuit driving gear 114 rotates a first angle and drives the main circuit energy storage part 120 to rotate and store energy, and the pre-charging driving gear 113 rotates a second angle and drives the pre-charging circuit energy storage part 130 to rotate and store energy; when the main circuit energy storage part 120 rotates to a preset position, it can release energy and drive the main circuit switch body 210 of the fusion switch 200 to close; when the pre-charging circuit energy storage part 130 rotates to a preset position, it can release energy and drive the pre-charging circuit switch body 220 of the fusion switch 200 to close; wherein, the second angle is greater than the first angle, so that the pre-charging circuit energy storage part 130 rotates to the preset position before the main circuit energy storage part 120, so that the pre-charging circuit switch body 220 is closed before the main circuit switch body 210; similarly, the pre-charging circuit switch body 220 is opened before the main circuit switch body 210.

[0043] For example, when the rotating shaft 111 rotates 180 degrees, the main circuit drive gear 114 rotates 60 degrees and the precharge drive gear 113 rotates 90 degrees; the main circuit energy storage part 120 and the precharge circuit energy storage part 130 rotate to 45 degrees, which is the balance dead point. When the precharge drive gear 113 drives the energy storage part 130 to rotate to 45 degrees, the main circuit drive gear 114 drives the main circuit energy storage part 120 to rotate to 30 degrees. Therefore, the precharge circuit energy storage part 130 rotates to the balance dead point before the main circuit energy storage part 120, realizing that the precharge circuit switch body 220 closes first and the main circuit switch body 210 closes later. Similarly, the precharge circuit switch body 220 opens before the main circuit switch body 210.

[0044] It should be noted that the transmission ratio relationship can be changed by adjusting the radius ratio of the main circuit drive gear 114 to the main circuit rotating shaft gear 112 and the radius ratio of the precharge drive gear 113 to the precharge rotating shaft gear 115. By increasing the radius of the main circuit rotating shaft gear 112 or decreasing the radius of the main circuit drive gear 114, the transmission ratio can be reduced, resulting in a decrease in the output speed and an increase in the torque.

[0045] Alternatively, the transmission ratio relationship can also be changed by adjusting the number of teeth of the main circuit drive gear 114 and the main circuit rotating shaft gear 112, and the number of teeth of the precharge drive gear 113 and the precharge rotating shaft gear 115. Increasing the number of teeth of the main circuit rotating shaft gear 112 or decreasing the number of teeth of the main circuit drive gear 114 can reduce the transmission ratio, resulting in a decrease in the output speed and an increase in the torque.

[0046] By adjusting the radius ratio or the number of teeth of the main circuit drive gear 114 to the precharge drive gear 113, the transmission ratio between the main circuit drive gear 114 and the precharge drive gear 113 can be adjusted to meet the requirement that the precharge circuit energy storage part 130 rotates to the preset position before the main circuit energy storage part 120, realizing that the precharge circuit switch body 220 closes first and the main circuit switch body 210 closes later; at the same time, the layout of the main circuit drive gear 114 and the precharge drive gear 113 is more flexible.

[0047] The operating mechanism 100 provided in the present application includes a driving component 110 and a main circuit energy storage part 120 and a pre-charging circuit energy storage part 130 respectively connected to the driving component 110 by transmission; the driving component 110 includes a rotating shaft 111 and a main circuit driving gear 114 and a pre-charging driving gear 113 respectively arranged on the rotating shaft 111, the rotating shaft 111 is driven to rotate by a preset angle, the main circuit driving gear 114 rotates by a first angle and drives the main circuit energy storage part 120 to rotate and store energy, and the pre-charging driving gear 113 rotates by a second angle and drives the pre-charging circuit energy storage part 130 to rotate and store energy; when the main circuit energy storage part 120 rotates to a preset position, it can release energy and drive the main circuit switch body 210 of the fusion switch 200 to close; when the pre-charging circuit energy storage part 130 rotates to a preset position, it can release energy and drive the pre-charging circuit switch body 220 of the fusion switch 200 to close; wherein, the second angle is greater than the first angle, so that the pre-charging circuit energy storage part 130 rotates to the preset position before the main circuit energy storage part 120. The operating mechanism 100 obtained by the above design can adjust the radius ratio of the main circuit drive gear 114 and the pre-filling drive gear 113 to match the layout position of the main circuit switch body 210 and the pre-filling circuit switch body 220 when closing the switch, thereby improving the flexibility of the overall layout while ensuring good opening and closing.

[0048] In one possible implementation mode of the present application, the drive assembly 110 also includes a main circuit shaft gear 112, which is connected to the main circuit energy storage unit 120 via a main circuit drive gear 114; the main circuit drive gear 114 can drive the main circuit shaft gear 112 to rotate, thereby driving the main circuit energy storage unit 120 to rotate and store energy.

[0049] Specifically, Figure 2 As shown, in order to improve the stability and reliability of the transmission connection between the driving component 110 and the main circuit energy storage part 120, the driving component 110 also includes a main circuit rotating shaft gear 112, one side of the main circuit rotating shaft gear 112 is transmission-connected to the main circuit energy storage part 120, and the main circuit rotating shaft gear 112 is meshed with the main circuit driving gear 114. When the rotating shaft 111 rotates, it can drive the main circuit driving gear 114 to rotate, and then drive the main circuit rotating shaft gear 112 to rotate, and the main circuit rotating shaft gear 112 can drive the main circuit energy storage part 120 to rotate and store energy.

[0050] In one possible implementation of the present application, the drive assembly 110 also includes a pre-filling shaft gear 115, and the pre-filling drive gear 113 is transmission-connected to the pre-filling circuit energy storage unit 130 via the pre-filling shaft gear 115; the pre-filling drive gear 113 can drive the pre-filling shaft gear 115 to rotate, thereby driving the pre-filling circuit energy storage unit 130 to rotate and store energy.

[0051] Specifically, in order to improve the stability and reliability of the transmission connection between the driving component 110 and the pre-charge circuit energy storage unit 130, the driving component 110 further includes a pre-charge rotating shaft gear 115. One side of the pre-charge rotating shaft gear 115 is in transmission connection with the pre-charge circuit energy storage unit 130. The pre-charge rotating shaft gear 115 meshes with the pre-charge driving gear 113. When the rotating shaft 111 rotates, it can drive the pre-charge driving gear 113 to rotate, and then drive the pre-charge rotating shaft gear 115 to rotate. The pre-charge rotating shaft gear 115 can drive the pre-charge circuit energy storage unit 130 to rotate and store energy.

[0052] Exemplarily, the main circuit energy storage unit 120 includes an energy storage member 141, an input rotating shaft 142 and an output rotating shaft 143 that are coaxially arranged and spaced apart; the input rotating shaft 142 is connected to the output rotating shaft 143 through the energy storage member 141; the side of the output rotating shaft 143 facing away from the input rotating shaft 142 is in transmission connection with the contact assembly of the main circuit switch body 210. The main circuit rotating shaft gear 112 drives the energy storage member 141 to store energy and drives the output rotating shaft 143 to rotate through the input rotating shaft 142 respectively; and when the input rotating shaft 142 rotates to a preset position, the energy storage member 141 releases energy and drives the contact assembly of the main circuit switch body 210 to close or open through the output rotating shaft 143.

[0053] Specifically, as Figure 2 shown, the main circuit energy storage unit 120 includes an input rotating shaft 142 and an output rotating shaft 143 that are coaxially arranged and spaced apart from each other. One side of the input rotating shaft 142 is in transmission connection with the main circuit rotating shaft gear 112. When the main circuit rotating shaft gear 112 rotates, it can drive the input rotating shaft 142 to rotate together.

[0054] The energy storage member 141 is arranged between the input rotating shaft 142 and the output rotating shaft 143, and both sides of the energy storage member 141 are respectively connected to the input rotating shaft 142 and the output rotating shaft 143. The side of the output rotating shaft 143 facing away from the input rotating shaft 142 is in transmission connection with the contact assembly of the main circuit switch body 210.

[0055] When the main circuit rotating shaft gear 112 drives the input rotating shaft 142 to rotate, it can synchronously drive the energy storage member 141 to rotate, and the energy storage member 141 compresses and stores energy; when the input rotating shaft 142 drives the energy storage member 141 to rotate to a preset position, for example, when the energy storage member 141 rotates to the horizontal position, the energy storage member 141 is compressed to the minimum value and releases energy to drive the output rotating shaft 143 to rotate, so that the output rotating shaft 143 drives the contact assembly of the main circuit switch body 210 to close or open.

[0056] Exemplarily, as Figure 2As shown, the pre-charging circuit energy storage part 130 includes an energy storage member 141, an input shaft 142 and an output shaft 143 which are coaxial and spaced apart; the input shaft 142 is connected to the output shaft 143 via the energy storage member 141; the side of the output shaft 143 away from the input shaft 142 is transmission-connected to the contact assembly of the pre-charging circuit switch body 220, and the pre-charging shaft gear 115 drives the energy storage member 141 to store energy and drives the output shaft 143 to rotate via the input shaft 142; and when the input shaft 142 rotates to a preset position, the energy storage member 141 releases energy and drives the contact assembly of the pre-charging circuit switch body 220 to close or open via the output shaft 143.

[0057] Specifically, Figure 2 As shown, the pre-filling circuit energy storage unit 130 includes an input shaft 142 and an output shaft 143 which are coaxially arranged and spaced apart from each other. One side of the input shaft 142 is transmission-connected to the pre-filling shaft gear 115. When the pre-filling shaft gear 115 rotates, it can drive the input shaft 142 to rotate together.

[0058] The energy storage member 141 is disposed between the input shaft 142 and the output shaft 143 , and the two sides of the energy storage member 141 are respectively connected to the input shaft 142 and the output shaft 143 , and the side of the output shaft 143 away from the input shaft 142 is transmission-connected to the contact assembly of the pre-charging circuit switch body 220 .

[0059] When the pre-charging shaft gear 115 drives the input shaft 142 to rotate, it can synchronously drive the energy storage component 141 to rotate, and the energy storage component 141 compresses and stores energy; when the input shaft 142 drives the energy storage component 141 to rotate to a preset position, for example, when the energy storage component 141 rotates to a horizontal position, the energy storage component 141 is compressed to a minimum value and releases energy to drive the output shaft 143 to rotate, so that the output shaft 143 drives the contact assembly of the pre-charging circuit switch body 220 to close.

[0060] In one possible implementation mode of the present application, the energy storage member 141 includes a connecting plate 1411, an elastic member 1412 and a limiting plate 1413; an opening 1413a is provided in the middle of the limiting plate 1413, one end of the connecting plate 1411 is inserted into the opening 1413a, and the other end is connected to the input rotating shaft 142 and the output rotating shaft 143; the limiting plate 1413 is used to limit the swing angle of the connecting plate 1411 relative to the limiting plate 1413 through the opening 1413a, and the elastic member 1412 is sleeved on the connecting plate 1411.

[0061] Specifically, Figure 3 and Figure 4As shown, the energy storage component 141 includes a limit plate 1413. The limit plate 1413 is disposed inside the housing of the fusion switch 200. Preferably, there are two limit plates 1413, and the two limit plates 1413 are oppositely disposed on opposite sides of the input rotating shaft 142. An opening 1413a is provided in the middle of the limit plate 1413. The end of the connection plate 1411 can be inserted into the opening 1413a and can rotate relative to the opening 1413a. The limit plate 1413 is used to limit the swinging angle of the connection plate 1411 relative to the limit plate 1413 through the opening 1413a.

[0062] One end of the connection plate 1411 facing away from the limit plate 1413 is disposed between the input rotating shaft 142 and the output rotating shaft 143 and is respectively connected to the input rotating shaft 142 and the output rotating shaft 143. The elastic member 1412 is sleeved on the connection plate 1411. When the input rotating shaft 142 is driven to rotate, it can drive the connection plate 1411 to rotate and compress the elastic member 1412 to store energy in the elastic member 1412. When the connection plate 1411 rotates to a preset position, the elastic member 1412 is compressed to the minimum value and releases energy to drive the output rotating shaft 143 to rotate, so that the output rotating shaft 143 drives the contact assembly of the main circuit switch body 210 or the pre-charge circuit switch body 220 of the fusion switch 200 to close.

[0063] In an implementable manner of the present application, the operating mechanism 100 further includes a motor 150. A driving gear 151 is provided on the output shaft of the motor 150; the driving component 110 further includes a driven gear 116 sleeved on the rotating shaft 111. The driving gear 151 is in transmission connection with the driven gear 116. The motor 150 drives the driven gear 116 to rotate through the driving gear 151, and then drives the rotating shaft 111 to rotate.

[0064] Specifically, as Figure 5 shown, the operating mechanism 100 includes a motor 150. The motor 150 is drivingly connected to an output shaft, and a driving gear 151 is sleeved on the output shaft; a driven gear 116 is sleeved on the rotating shaft 111, and the driven gear 116 can be engaged with the driving gear 151. The motor 150 can drive the driving gear 151 to rotate through the rotating shaft 111, and then drive the driven gear 116 to rotate to drive the rotating shaft 111 to rotate. Through the above settings, the opening and closing of the main circuit switch body 210 and the pre-charge circuit switch body 220 of the fusion switch 200 can be realized by electrically controlling the operating mechanism 100, and the remote control of the opening and closing is realized.

[0065] Further, at least one transmission gear 152 is provided between the driving gear 151 and the driven gear 116. When the transmission gear 152 includes one, both sides of the transmission gear 152 are respectively engaged with the driving gear 151 and the driven gear 116; when the transmission gear 152 includes multiple ones, the multiple transmission gears 152 are stacked and adjacent transmission gears 152 are engaged with each other, and the two transmission gears 152 at both ends are respectively engaged with the driving gear 151 and the driven gear 116.

[0066] Specifically, a transmission gear 152 is further provided between the driving gear 151 and the driven gear 116, and at least one transmission gear 152 is provided. The setting of the transmission gear 152 can better match the positional layout between the driving gear 151 and the driven gear 116, so that a better transmission relationship is achieved between the driving gear 151 and the driven gear 116, and the stability and reliability of the opening or closing of the fusion switch 200 are improved.

[0067] When the transmission gear 152 includes one, both sides of the transmission gear 152 are respectively engaged with the driving gear 151 and the driven gear 116, and the driving gear 151 drives the rotation of the driven gear 116 through the transmission gear 152, thereby driving the rotation of the rotating shaft 111; when the transmission gear 152 includes multiple ones, as Figure 5 shown, the multiple transmission gears 152 are stacked and adjacent transmission gears 152 are engaged with each other, and the two transmission gears 152 at the head and tail ends are respectively engaged with the driving gear 151 and the driven gear 116, so that the driving gear 151 drives the driven gear 116 to rotate through the multiple transmission gears 152 in sequence, thereby driving the rotation of the rotating shaft 111.

[0068] In another feasible embodiment of the present application, the operating mechanism 100 further includes a handle (not shown in the figure), and the handle is connected to the end of the rotating shaft 111 to manually control the operating mechanism 100 to realize the opening and closing of the fusion switch 200.

[0069] Through the setting of the handle, the rotation of the rotating shaft 111 can be driven in a manual control manner, making the closing and opening processes of the fusion switch 200 faster and more efficient.

[0070] On the other hand, an embodiment of the present application provides a fusion switch 200, such as Figure 6As shown in the figure, it includes an operating mechanism 100, a pre-charge circuit switch body 220 and a main circuit switch body 210 that are respectively connected to the operating mechanism 100. The pre-charge circuit switch body 220 and the main circuit switch body 210 are stacked, and the operating mechanism 100 is located on one side of the pre-charge circuit switch body 220 and the main circuit switch body 210; by manually or electrically controlling the operating mechanism 100, when closing the switch, the pre-charge circuit switch body 220 is driven to close first, and the main circuit switch body 210 closes later. After the main circuit switch body 210 closes, it drives the pre-charge circuit switch body 220 to open; when opening the switch, it drives the main circuit switch body 210 to open.

[0071] Specifically, the driving component 110 of the operating mechanism 100 includes a rotating shaft 111, a main circuit driving gear 114 and a pre-charge driving gear 113 that are respectively sleeved on the rotating shaft 111. The main circuit driving gear 114 and the pre-charge driving gear 113 have a preset radius ratio, and the preset radius ratio is greater than 1. Therefore, it can calculate the rotation angles corresponding to the main circuit rotating shaft gear 112 and the pre-charge rotating shaft gear 115 when closing the switch according to the positional layout between the main circuit switch body 210, the pre-charge circuit switch body 220 and the operating mechanism 100, and calculate and adjust the preset radius ratio and the setting position of the main circuit driving gear 114 and the pre-charge driving gear 113 correspondingly according to the rotation angles to ensure that the operating mechanism 100 can realize the closing of the main circuit switch body 210 and the pre-charge circuit switch body 220 of the fusion switch 200. Among them, the specific structure and beneficial effects of the operating mechanism 100 have been introduced in detail above and will not be elaborated here.

[0072] The fusion switch 200 obtained by the above design can, according to the rotation angles corresponding to the layout positions of the main circuit switch body 210 and the pre-charge circuit switch body 220 when closing the switch, cooperate with the adjustment of the radius ratio of the main circuit driving gear 114 and the pre-charge driving gear 113 of the operating mechanism 100, improving the flexibility of the internal layout and the space utilization rate of the fusion switch 200.
