[0024] In order to make the purpose of the application, technical scheme and advantage more clear and obvious, the following further detailed description of the application is combined with the drawings through specific embodiment. It should be understood that the described embodiment is a part of the embodiment of the application, not all the embodiment.

Numerous specific details are provided in the following description to give a thorough understanding of embodiments of this application. However, those skilled in the art will recognize that the technical solutions of this application can be practiced without one or more of the specific details, or other methods, components, apparatuses, steps, etc., can be employed. In other instances, well-known methods, apparatuses, implementations, or operations are not shown or described in detail to avoid obscuring various aspects of this application.

[0026] Manual disconnect switches, as a key electrical isolation device in modern power systems, are widely used in substations, power plants, and industrial power distribution systems. However, existing manual disconnect switches rely on manual operation by on-site personnel, which generally suffers from low operating efficiency, high labor intensity, and high risk of misoperation. For example, in some large substations, the control room is far from the equipment installation point, requiring operators to frequently travel between the two locations, which not only consumes a lot of time and energy but also increases the complexity of operation and the probability of errors. In addition, manual operation poses a high safety risk in high-voltage environments, especially during inclement weather or at night, when the operator's visibility and operating conditions are limited, further increasing the possibility of misoperation. Therefore, manual disconnect switches can no longer meet the automation, intelligence, and safety requirements of modern power systems. To address the above problems, this utility model provides an operating mechanism and a disconnect switch for use as a disconnect switch.

[0027] like Figure 1 The schematic diagram of the disconnecting switch device shown includes a disconnecting switch 10 and an operating mechanism 100 for the disconnecting switch 10. The operating mechanism 100 includes an electric drive unit 101, a control unit 102, and a transmission mechanism 103. Preferably, the electric drive unit 101 includes a motor; the control unit 102 includes a position detection unit 1020; and the transmission mechanism 103 includes a turbine shaft 1030, a linkage mechanism 1031, an output shaft crank arm 1032, and a transmission rod 1033. The electric drive unit 101 is configured to drive the transmission mechanism 103, and the transmission mechanism 103 is configured to drive the closing and opening actions of the disconnecting switch 10. The control unit 102 is configured to control the operation of the electric drive unit 101 in different operating modes, such as start, stop, first drive mode, and second drive mode. The control unit 102 can control the operation of the electric drive unit 101 via wired or wireless means. The position detection unit 1020 of the control unit 102 is configured to determine whether the disconnecting switch 10 has reached the closed or open position based on the rotational position of the turbine shaft 1030 of the transmission mechanism 103, and to stop the electric drive unit 101 when the disconnecting switch 10 reaches the closed or open position.

[0028] In one embodiment, the linkage mechanism 1031 is a four-bar linkage mechanism, including a crank 01, a connecting rod 02, a rocker 03, and a frame 04. Among them, the crank 01 is driven by an external power source (such as an electric drive unit 101) as a driving component to realize rotary motion; the connecting rod 02 connects the crank 01 and the rocker 03, responsible for converting the rotary motion of the crank 01 into the reciprocating swing motion of the rocker 03, and transmitting the corresponding force; the frame 04 is a fixed support structure, providing installation reference and stable motion environment for each component. Through the coordinated action of each component, the four-bar linkage mechanism can realize specific motion conversion.

[0029] In this embodiment, the power output end of the electric drive unit 101 is connected to the turbine shaft 1030, the first end of the turbine shaft 1030 is connected to the crank 01 of the linkage mechanism 1031, the rocker 03 of the linkage mechanism 1031 is connected to the output shaft rocker arm 1032, the output shaft rocker arm 1032 is connected to the main shaft rocker arm 11 of the isolation switch 10 through the transmission rod 1033, and the movable contact of the isolation switch 10 is arranged on the main shaft rocker arm 11.

[0030] In some embodiments of the present application, the electric drive unit 101 can also include a speed reduction device connected to the electric motor. The speed reduction device is configured to adjust the output speed and torque of the electric motor to meet the power output requirements of the electric drive unit 101.

[0031] In one embodiment, when the control unit 102 receives a closing command, the control unit 102 controls the electric drive unit 101 to start, and then controls the electric drive unit 101 to enter a first driving mode, that is, controls the rotor of the electric motor to rotate in a first direction (for example, forward rotation) to drive the turbine shaft 1030 to rotate, the turbine shaft 1030 drives the connecting rod mechanism 1031 to act, the connecting rod mechanism 1031 drives the output shaft crank 1032 to act, the output shaft crank 1032 in turn drives the main shaft crank 11 to move upward through the transmission rod 1033, at the same time, the position detection unit 1020 detects the rotating position of the turbine shaft 1030 and instructs the control unit 102 to control the electric drive unit 101 to stop when the main shaft crank 11 reaches the closing position of the disconnecting switch 10, and finally realizes the safe closing of the moving contact and the static contact of the disconnecting switch 10; when the control unit 102 receives an opening command, the control unit 102 controls the electric drive unit 101 to start, and then controls the electric drive unit 101 to enter a second driving mode, that is, controls the rotor of the electric motor to rotate in a second direction (for example, reverse rotation) to drive the turbine shaft 1030 to rotate in the opposite direction of the first driving mode, the turbine shaft 1030 drives the connecting rod mechanism 1031 to act, the connecting rod mechanism 1031 drives the output shaft crank 1032 to act, the output shaft crank 1032 in turn drives the main shaft crank 11 to move downward through the transmission rod 1033, at the same time, the position detection unit 1020 detects the rotating position of the turbine shaft 1030 and instructs the control unit 102 to control the electric drive unit 101 to stop when the main shaft crank 11 reaches the opening position of the disconnecting switch 10, and finally realizes the safe opening of the moving contact and the static contact of the disconnecting switch 10.

[0032] In some embodiments of the present application, the position detection unit 1020 at least includes a first travel switch and a second travel switch, and as shown in Figure 2 the second end of the turbine shaft 1030 opposite to the first end is provided with a cam 1031-1. As shown in Figure 6 the schematic diagram of the relative positions of the first travel switch, the second travel switch and the cam according to the embodiments of the present application, the first travel switch 1020A and the second travel switch 1020B are arranged on both sides of the cam 1030-1. The rotating position of the turbine shaft 1030 includes a first rotating position and a second rotating position. Wherein, when the turbine shaft 1030 rotates to the first rotating position, the main shaft crank 11 reaches the closing position of the disconnecting switch 10, the cam 1030-1 contacts the first travel switch 1020A, so that the first travel switch 1020A is disconnected; when the turbine shaft 1030 rotates to the second rotating position, the main shaft crank 11 reaches the opening position of the disconnecting switch 10, the cam 1030-1 contacts the second travel switch 1020B, so that the second travel switch 1020B is disconnected.

[0033] In some embodiments of the utility model, see Figure 3 As shown in the circuit schematic view of the control unit 102 for controlling the operation of the motor (shown in the dashed box), the control unit 102 can also include a closing circuit (i.e. the circuit for controlling the forward rotation of the motor) and an opening circuit (i.e. the circuit for controlling the reverse rotation of the motor), the closing circuit includes a first contactor KM1 and a closing button SB2 for controlling the first contactor KM1, and the opening circuit includes a second contactor KM2 and an opening button SB3 for controlling the second contactor KM2. Specifically, pressing the closing button SB2, the coil of the first contactor KM1 is powered, and the main contact is attracted to make the closing circuit closed; pressing the opening button SB3, the coil of the second contactor KM2 is powered, and the main contact is attracted to make the opening circuit closed.

[0034] In some embodiments of the utility model, as shown in Figure 3 Preferably, the first contactor KM1 includes main contacts KM1-3, KM1-4 and KM1-5, and normally open contacts KM1-1 and normally closed contacts KM1-2; the second contactor KM2 includes main contacts KM2-3, KM2-4 and KM2-5, and normally open contacts KM2-1 and normally closed contacts KM2-2.

[0035] In some embodiments of the utility model, the disconnector 10 is a capacitor disconnector. As shown in Figure 4 As shown in the circuit schematic view of the control unit according to the embodiment of the utility model when the disconnector is closed, when closing is needed, the closing button SB2 is pressed, the coil of the first contactor KM1 is powered, and the main contacts KM1-3, KM1-4 and KM1-5 are closed, which makes the current in the motor flow in the direction from node B to node A, thereby making the circuit for controlling the forward rotation of the motor conductive, the forward rotation of the motor drives the turbine shaft 1030 to rotate counterclockwise, the turbine shaft 1030 drives the connecting rod mechanism 1031 to act, the connecting rod mechanism 1031 drives the output shaft crank arm 1032 to act, and the output shaft crank arm 1032 further drives the main shaft crank arm 11 to move upward through the transmission rod 1033.

[0036] Furthermore, the normally open contact KM1-1 of the first contactor KM1 is connected in parallel with the closing button SB2, the normally closed contact KM2-2 of the second contactor KM2 is connected in series in the closing circuit, while the normally closed contact KM1-2 of the first contactor KM1 is connected in series in the opening circuit, and the normally open contact KM2-1 of the second contactor KM2 is connected in parallel with the opening button SB3. When the closing button SB2 is pressed, the normally open contact KM1-1 of the first contactor KM1 closes, and the normally closed contact KM1-2 opens. The closing of the normally open contact KM1-1 of the first contactor KM1 short-circuits the closing button SB2. Therefore, during the operation after closing, even if the user accidentally presses the closing button SB2, it will not affect the isolating switch. Furthermore, the opening of the normally closed contact KM1-2 of the first contactor KM1 causes the opening circuit to fail. Therefore, even if the user accidentally presses the opening button SB3, it will not trigger the opening of the isolating switch. When the main shaft crank arm 11 reaches the closed position of the disconnecting switch 10, the cam 1030-1 on the turbine shaft 1030 will contact the first limit switch 1020A, thereby causing the first limit switch 1020A to open, and then the coil of the first contactor KM1 will be de-energized, the main contacts KM1-3, KM1-4 and KM1-5 will open, the motor will be de-energized, the operating mechanism 100 will stop operating, and the disconnecting switch 10 will complete the closing.

[0037] Similarly, such as Figure 5 The circuit diagram shown below illustrates the control unit for the disconnecting switch when it is tripped according to an embodiment of the present invention. When tripping is required, pressing the tripping button SB3 energizes the coil of the second contactor KM2, closing the main contacts KM2-3, KM2-4, and KM2-5. This causes the current in the motor to flow from node A to node B, thus activating the circuit controlling the reverse rotation of the motor. The reverse rotation of the motor drives the turbine shaft 1030 to rotate clockwise. The turbine shaft 1030 drives the linkage mechanism 1031, which in turn drives the output shaft crank arm 1032. The output shaft crank arm 1032 then drives the main shaft crank arm 11 to move downwards via the transmission rod 1033. When the tripping button SB3 is pressed, the normally open contact KM2-1 of the second contactor KM2 closes, and the normally closed contact KM2-2 opens, forming an electrical interlock similar to that described in the closing process. When the main shaft crank arm 11 reaches the open position of the disconnecting switch 10, the cam 1030-1 on the turbine shaft 1030 will contact the second limit switch 1020B, thereby causing the second limit switch 1020B to open. Consequently, the coil of the second contactor KM2 is de-energized, the main contacts KM2-3, KM2-4 and KM2-5 are opened, the motor is de-energized, the operating mechanism 100 stops operating, and the disconnecting switch 10 completes the opening.

[0038] This utility model realizes the electric operation of the disconnecting switch 10 through the above embodiments. On-site operators only need to press a button in the control room to easily complete the opening and closing operation of the disconnecting switch. The whole process is simple and easy to implement, which greatly improves work efficiency, reduces the consumption of manpower and material resources, and demonstrates the convenience and efficiency brought by modern technology to industrial operation.

[0039] Furthermore, this invention achieves electrical interlocking in the circuit by configuring the normally open contacts KM1-1 and KM1-2 of the first contactor KM1 and the normally open contacts KM2-1 and KM2-2 of the second contactor KM2. This effectively prevents user misoperation or accidental button touches, improving circuit safety. In some embodiments of this invention, such as... Figure 1 As shown, the operating mechanism 100 may further include a manual-to-electric switch plate 104 and a handle 105. The handle 105 is connected to the turbine shaft 1030 and configured to manually drive the turbine shaft 1030. The manual-to-electric switch plate 104 is configured to switch between manual and electric operation modes of the disconnect switch 10. In manual operation mode, the turbine shaft 1030 is driven by the handle 105; in electric operation mode, the turbine shaft 1030 is driven by the electric drive unit 101. The switching process between manual and electric operation modes is not described in detail here.

[0040] With the above settings, users can choose to operate the disconnector switch 10 manually or electrically, offering flexibility and convenience. In the event of a malfunction in components related to the electrically operated mode, such as the electric drive unit 101, users can immediately select the manual operation mode to close or open the disconnector switch 10, avoiding unnecessary losses due to the inability to operate the disconnector switch 10 electrically.

[0041] In some embodiments of this utility model, such as Figure 1 As shown, the operating mechanism 100 may also include a buffer device 106, which is disposed below the linkage mechanism 1031 and is configured to buffer the movement of the linkage mechanism 1031.

[0042] Another embodiment of this utility model provides an isolating switch system, see [link to relevant documentation] Figure 7 The schematic diagram of the disconnecting switch system according to an embodiment of the present utility model shown includes a switch cabinet 600 and a disconnecting switch device 200 disposed in the switch cabinet 600. Its structure is more compact and its safety is higher.

[0043] In embodiments of this utility model, the rotational position of the turbine shaft refers to the specific angle or position of the turbine shaft during rotation. Further, in Figure 2In the illustrated scheme, the rotational position of the turbine shaft refers to the rotational position of the cam of the turbine shaft. Those skilled in the art can understand that the rotational position of the turbine shaft can also refer to the rotational position of other marked components of the turbine shaft.

[0044] In the embodiments of the utility model, the connection between assemblies, such as the connection between the power output end of the electric drive unit 101 and the turbine shaft 1030 or the connection between the turbine shaft 1030, the connecting rod mechanism 1031 and the output shaft crank arm 1032, includes but is not limited to gear connection, key connection and bolt connection and the like.

[0045] The electric operation of the disconnector realized in the utility model is convenient and efficient, saves time and effort, is stable and fast in operation speed, and can be opened or closed in time according to system or user demand. The utility model controls the closing and opening of the disconnector through the electric operation mode, reduces the complexity and time cost of the operation of the disconnector, improves the operation efficiency, simultaneously realizes the accurate control of the opening and closing positions, avoids manual operation errors, is helpful to the reliable operation of the system, and further improves the safety performance of the system. At the same time, remote operation can also be away from high-voltage equipment.
