[0033] Please refer to Figure 1 And Figure 2 The embodiment provides an electric operating structure 100 of a disconnecting switch, which comprises an electric operating module 110 and an operating mechanism 120 connected in sequence;The electric operating module 110 comprises a motor 111 and a transmission assembly 112, the transmission assembly 112 comprises a driving gear 1121 and a plurality of driven gear parts 1122 engaged in sequence, and the plurality of driven gear parts 1122 are arranged in layers;One of the driven gear parts 1122 is engaged with the driving gear 1121, and the transmission assembly 112 is drivingly connected with the operating mechanism 120 through the driven gear part 1122;The motor 111 can drive the driving gear 1121 and the plurality of driven gear parts 1122 to rotate in sequence, and then drive the operating mechanism 120 to rotate, so that the operating mechanism 120 drives the disconnecting switch to close or open.

[0034] Specifically, as Figure 1As shown, the present application provides an electric operating structure 100 of a disconnecting switch, which comprises an electric operating module 110 and an operating mechanism 120. The electric operating module 110 can receive a disconnecting or closing signal of the disconnecting switch issued by a control system, and drive the operating mechanism 120 to rotate according to the signal, so that the operating mechanism 120 drives the disconnecting switch to close or disconnect. The automatic disconnecting or closing of the disconnecting switch is realized by the electric operating mode, which can save the labor cost, improve the automation level of the disconnecting switch, and enrich the application scenarios of the disconnecting switch.

[0035] As shown in Figure 1 and Figure 2 , the electric operating module 110 comprises a motor 111 and a transmission assembly 112. The motor 111 can be connected with the control system to receive the disconnecting or closing signal of the disconnecting switch issued by the control system, and drive the transmission assembly 112 to rotate according to the signal. The transmission assembly 112 comprises a driving gear 1121 and a plurality of driven gear parts 1122. In order to make the structure of the transmission assembly 112 more compact, thereby reducing the space volume of the electric operating structure, the plurality of driven gear parts 1122 are arranged in sequence and stacked to form a multi-layer structure. Such arrangement makes the size of the electric operating structure smaller, and at the same time, the plurality of driven gear parts 1122 form a multi-stage transmission, so that the output torque of the motor 111 is larger, and the reliability of the disconnecting or closing process is improved.

[0036] As shown in Figure 1 and Figure 2 , the driving gear 1121 of the transmission assembly 112 is connected with the output end of the motor 111, one of the driven gear parts 1122 is engaged with the driving gear 1121, and the transmission assembly 112 is drivingly connected with the operating mechanism 120 through the driven gear part 1122. The output end of the motor 111 drives the driving gear 1121 to rotate, and in turn drives a plurality of driving gears 1121 to rotate, so as to realize the rotation of the operating mechanism 120, and realize the closing or disconnecting of the disconnecting switch through the rotation of the operating mechanism 120.

[0037] It should be noted that, please refer to Figure 1 , Figure 2 and Figure 3 , in an embodiment of the present application, the driven gear part 1122 comprises a gear disc 1122a and a gear column 1122b connected fixedly, and the gear column 1122b is arranged on the gear disc 1122a; the gear discs 1122a of the plurality of driven gear parts 1122 are arranged in layers, and the adjacent two driven gear parts 1122 are engaged with each other through the gear disc 1122a and the gear column 1122b.

[0038] Specifically, in order to ensure that the plurality of driven gear parts 1122 can be well engaged while being arranged in layers, as shown in Figure 3As shown, the driven gear section 1122 includes a gear disk 1122a and a gear column 1122b that are fixedly connected. The gear disks 1122a of the multiple driven gear sections 1122 are stacked, and two adjacent driven gear sections 1122 mesh with each other through the gear disk 1122a and the gear column 1122b to achieve good meshing transmission.

[0039] like Figure 1 As shown, in one specific embodiment of this application, there are three driven gear sections 1122. The gear disks 1122a of the three driven gear sections 1122 are stacked on top of each other, and adjacent driven gear sections 1122 mesh with the gear column 1122b in the stacking direction through the gear disks 1122a. This achieves a four-stage transmission where the driving gear 1121 sequentially drives the three driven gear sections 1122, and the last driven gear section 1122 drives the operating mechanism 120 to rotate. This increases the output torque of the motor 111, making the opening or closing process of the disconnecting switch more reliable and efficient. It should be noted that this application does not limit the specific number of driven gear sections 1122. In actual assembly, the number can be adjusted according to the torque required for opening or closing the switch.

[0040] Secondly, in a preferred embodiment of this application, there are three driven gear sections 1122, which mesh sequentially. One driven gear section 1122 meshes with the driving gear 1121, and the other driven gear section 1122 meshes with the transfer gear disk 1123 outside the rotating shaft 121. This achieves the meshing of the driving gear 1121 with one of the driven gear sections 1122, the meshing between two adjacent driven gear sections 1122, and the meshing of the other driven gear section 1122 with the transfer gear disk 1123, forming four sets of meshing gears that transmit power sequentially. This increases the output torque of the motor while minimizing the size of the electric control structure.

[0041] The application provides an electric operating structure 100 of an isolating switch, comprising an electric operating module 110 and an operating mechanism 120 connected in sequence; the electric operating module 110 comprises a motor 111 and a transmission assembly 112, the transmission assembly 112 comprises a driving gear 1121 and a plurality of driven gear parts 1122 engaged in sequence, and the plurality of driven gear parts 1122 are arranged in layers, so that the electric operating structure is more compact, thereby reducing the volume of the electric operating structure and being conducive to realizing the miniaturization of the isolating switch; meanwhile, the plurality of driven gear parts 1122 also realize multi-stage transmission of force, thereby improving the output torque of the motor 111; one of the driven gear parts 1122 is engaged with the driving gear 1121, and the transmission assembly 112 is in transmission connection with the operating mechanism 120 through the driven gear part 1122; the motor 111 can drive the driving gear 1121 and the plurality of driven gear parts 1122 to rotate in sequence, thereby driving the operating mechanism 120 to rotate, so that the operating mechanism 120 drives the isolating switch to close or open. The electric operating structure 100 of the isolating switch improves the space utilization of the electric operating structure while realizing the closing and opening of the isolating switch by electric operation, and is conducive to realizing the miniaturization of the isolating switch.

[0042] For example, as shown in Figure 3 , the operating mechanism 120 comprises a rotating shaft 121, the transmission assembly 112 further comprises a transfer gear disc 1123, the transfer gear disc 1123 is arranged in layers with one of the driven gear parts 1122 and is engaged with each other, the rotating shaft 121 is arranged in the middle of the transfer gear disc 1123 and is fixedly connected with the transfer gear disc 1123; the driven gear part 1122 can drive the transfer gear disc 1123 to rotate, so as to drive the rotating shaft 121 to rotate and realize the closing or opening of the isolating switch.

[0043] Specifically, in order to ensure that the transmission assembly 112 can reliably drive the operating mechanism 120 to rotate, as shown in Figure 3 , the transmission assembly 112 comprises a transfer gear disc 1123, the transfer gear disc 1123 is engaged with the last driven gear part 1122 and is arranged in layers with the gear disc 1122a thereof; the operating mechanism 120 comprises a rotating shaft 121, one end of the rotating shaft 121 is arranged in the middle of the transfer gear disc 1123, when the driven gear part 1122 drives the transfer gear disc 1123 to rotate, the rotating shaft 121 can be driven to rotate synchronously, so as to realize the opening or closing of the isolating switch.

[0044] In an implementable manner of the application, as shown in Figure 2 , in order to improve the reliability of the opening or closing of the isolating switch, the operating mechanism 120 further comprises a cam disc 122, one side of the cam disc 122 is connected with the rotating shaft 121 and the other side is connected with a movable contact of the isolating switch; the transmission assembly 112 can drive the rotating shaft 121 to drive the cam disc 122 to rotate, thereby driving the movable contact to rotate and realizing the closing or opening of the isolating switch.

[0045] Optionally, referring to Figure 2 and Figure 4 , the operating mechanism 120 further comprises a pawl 123 and an elastic member 124, the elastic member 124 is sleeved on the cam disc 122 and the end thereof abuts against the cam disc 122; the pawl 123 is arranged on one side of the cam disc 122 and is in the same plane with the cam disc 122, the pawl 123 can abut against the cam disc 122; the driving rotating shaft 121 is rotated to store energy for the elastic member 124; the driving rotating shaft 121 continues to rotate, the pawl 123 can move in a direction away from the cam disc 122 to abut against the cam disc 122, the elastic member 124 releases energy and drives the cam disc 122 to rotate, so that the disconnecting switch is closed.

[0046] Specifically, in order to improve the reliability and stability of the opening or closing of the disconnecting switch, referring to Figure 2 and Figure 4 , the operating mechanism 120 further comprises a pawl 123 and an elastic member 124, the pawl 123 is in the same plane with the cam disc 122; the rotating shaft 121 has an opening position and a closing position, when the rotating shaft 121 is rotated to the opening position, as shown in Figure 4 , the pawl 123 abuts against the cam disc 122, at this time the rotating shaft 121 cannot rotate the cam disc 122, and the disconnecting switch is in the opening state; during the rotating shaft 121 is rotated from the opening position to the closing position, the pawl 123 moves in a direction away from the cam disc 122, and the elastic member 124 sleeved on the cam disc 122 stores energy; when the rotating shaft 121 is rotated to the closing position, the cam disc 122 abuts against the pawl 123, the elastic member 124 releases energy and drives the cam disc 122 to rotate, so that the movable contact and the static contact are closed. Through the cooperation of the pawl 123, the cam disc 122 and the elastic member 124, the closing and opening process of the disconnecting switch is more rapid and efficient.

[0047] It should be noted that, in an embodiment of the present application, first, as shown in Figure 5 , the end of the pawl 123 is provided with a reset member 125, when the pawl 123 moves in a direction away from the cam disc 122, the reset member 125 stores energy, so that the pawl 123 has a tendency to move in a direction abutting against the cam disc 122.

[0048] Specifically, as shown in Figure 5As shown, a rotating column 126 is provided on the side of the pawl 123 away from the cam disk 122. The rotation axis 121 of the rotating column 126 is parallel to the rotation axis 121 of the rotating shaft 121. A reset member 125 is provided at the end of the pawl 123 and one end is connected to the rotating column 126. When the rotating shaft 121 rotates continuously, the pawl 123, which was originally in contact with the cam disk 122, moves toward the direction of releasing contact with the cam disk 122 under the force of the rotating shaft 121. At the same time, the reset member 125 drives the rotating column 126 to rotate, making the movement of the pawl 123 more stable and reliable. During the process of the pawl 123 moving toward the direction of releasing contact with the cam disk 122, the reset member 125 stores energy to provide a reset force for the pawl 123 to move toward the direction of contact with the cam disk 122.

[0049] Second, such as Figure 4 As shown, the cam disk 122 includes a disk body 1221, a first baffle 1222, and a connecting portion 1223. The first baffle 1222 is perpendicular to the disk body 1221, and the end of the elastic member 124 can abut against the side wall of the first baffle 1222. The connecting portion 1223 is located in the middle of the disk body 1221, and the elastic member 124 is sleeved on the outer periphery of the connecting portion 1223. The rotating shaft 121 is connected to the disk body 1221 through the connecting portion 1223. The rotating shaft 121 is provided with... The second baffle 1212 is located corresponding to the position of the first baffle 1222. The second baffle 1212 is perpendicular to the disk body 1221 and is located on the side of the first baffle 1222 away from the connecting part 1223. One end of the elastic member 124 abuts against the side wall of the second baffle 1212 and the other end abuts against the side wall of the first baffle 1222. The drive shaft 121 rotates, which can drive the end of the elastic member 124 that abuts against the second baffle 1212 to rotate, so that the elastic member 124 stores energy.

[0050] Specifically, such as Figure 4 As shown, the cam disk 122 includes a disk body 1221. The disk body 1221 has a columnar connecting portion 1223 in its middle. A rotating shaft 121 can be inserted into the connecting portion 1223 to connect with the cam disk 122. An elastic member 124 is sleeved on the outer periphery of the connecting portion 1223, which can limit the movement of the elastic member 124. Simultaneously, a first baffle 1222 is vertically arranged on the surface of the disk body 1221, and one end of the elastic member 124 can abut against the side wall of the first baffle 1222. Correspondingly, the rotating shaft 121 is provided with a second baffle 1212 corresponding to the position of the first baffle 1222. The second baffle 1212 is perpendicular to the disk body 1221 and located on the side of the first baffle 1222 away from the connecting portion 1223. The other end of the elastic member 124 abuts against the side wall of the second baffle 1212.

[0051] As the rotating shaft 121 rotates from the open position to the closed position, the pawl 123 moves in the direction of disengaging from the cam disc 122. At the same time, the side wall of the second baffle 1212 of the rotating shaft 121 can drive the end of the elastic element 124 that abuts against the second baffle 1212 to rotate, so that the elastic element 124 stores energy. When the rotating shaft 121 rotates to the closed position, the cam disc 122 disengages from the pawl 123. At this time, the elastic element 124 releases energy and drives the cam disc 122 to rotate, so that the moving contact and the stationary contact close.

[0052] Third, such as Figure 4 As shown, in order to improve the contact stability between the pawl 123 and the cam disk 122, a protrusion 1221a is provided on the edge of the disk body 1221, and a corresponding abutment groove 1232 is provided on the pawl 123. The protrusion 1221a can abut against the abutment groove 1232. The drive shaft 121 rotates to drive the elastic element 124 to store energy. The drive shaft 121 continues to rotate, and the pawl 123 can move in the direction of disengaging from the cam disk 122, so that the protrusion 1221a disengages from the abutment groove 1232, the elastic element 124 releases energy and drives the cam disk 122 to rotate, so that the disconnecting switch is closed.

[0053] Fourth, please refer to Figure 2 and Figure 4 To enable the rotating shaft 121 to quickly push the pawl 123 towards the direction of disengagement from the cam disk 122 during rotation, a thrust shaft 1211 is provided extending from the edge of the rotating shaft 121. The thrust shaft 1211 is perpendicular to the disk body 1221. Driving the rotating shaft 121 to rotate, the thrust shaft 1211 can contact and push the pawl 123, causing the pawl 123 to move in the direction of disengagement from the cam disk 122. Preferably, to enable the thrust shaft 1211 to quickly push the pawl 123, such as... Figure 4 As shown, the end of the pawl 123 is provided with a guide slope 1231. The guide slope 1231 facilitates the thrust shaft 1211 to quickly abut against the end of the pawl 123 and push it in the direction of disengaging from the cam disk 122 until the thrust shaft 1211 is locked in the abutment groove 1232.

[0054] For example, in one specific embodiment of this application, when the rotating shaft 121 is in the open position, there is a preset distance between the thrust shaft 1211 and the pawl 123.
