Description

Technical Field

[0001] This invention belongs to the field of power disconnect switch technology, specifically relating to an automatic opening and closing device for a 35kV disconnect switch. Background Technology

[0002] Disconnecting switches are indispensable electrical equipment in 35kV power systems, mainly used for isolating power sources, switching operations, and connecting and disconnecting low-current circuits. Their operating status directly affects the safety and reliability of the power system. Currently, most existing 35kV disconnecting switches are operated manually. Operators need to carry insulated rods to the equipment site to manually complete the opening and closing operations. This is not only labor-intensive and inefficient, but also carries risks of electric shock, accidental contact with equipment, and the safety hazards of working at heights. Especially in inclement weather, the safety and feasibility of manual operation are significantly reduced.

[0003] Chinese patent CN121938796A discloses a 35kV isolating switch opening and closing device, including a base plate, a contact unit, a transmission assembly, and a drive unit. The drive unit drives the transmission assembly to move, and the transmission assembly drives the second connecting part to contact or disconnect with the corresponding composite post insulator, thereby realizing closing or opening the switch. This solves the problem of poor safety in the prior art of manually opening and closing isolating switches at close range.

[0004] However, the above devices still have some shortcomings: when in use, operators still need to be on-site to apply external force by turning the handle, and use the first contact rod, second contact rod and contact piece to complete the opening and closing action. Remote control is not possible, and the degree of automation is insufficient. In addition, the drive unit is not precise enough to achieve accurate control of the opening and closing angle of the disconnector, which can easily lead to incomplete closing or incomplete opening, affecting the stability of the power system. Furthermore, there is a lack of an effective monitoring mechanism, which makes it impossible to grasp key operating parameters such as disconnector contact temperature and opening and closing position in real time, making it difficult to predict equipment failure in advance and easily causing safety accidents. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of existing technologies, such as inconvenient operation, low degree of automation, and lack of effective status monitoring, and to provide an automatic opening and closing device for a 35kV isolating switch.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an automatic opening and closing device for a 35kV isolating switch, comprising a fixed base, a switch body, an automatic drive mechanism, and an intelligent control mechanism. The fixed base includes symmetrically arranged side strips, and connecting plates are fixedly and symmetrically arranged between the side strips. The switch body is provided in three sets, and all three sets of switch bodies are installed on the outside of the side strips of the fixed base. The switch body includes a post insulator, a stationary contact assembly, a moving contact assembly, and a conductive switch. The post insulator is vertically fixed to the outside of the connecting plates. A stationary contact assembly is installed on the top of one set of post insulators, and a moving contact assembly is installed on the top of another set of post insulators. One end of the conductive switch is hinged to the moving contact assembly, and the other end can engage or disengage with the stationary contact assembly to realize the closing and opening of the switch. The automatic drive mechanism is connected to the main body of the knife switch and is used to provide the power required for the opening and closing of the knife switch, thereby driving the knife switch to open and close automatically. The intelligent control mechanism is electrically connected to the automatic drive mechanism and is used to receive remote control commands or local trigger signals to control the action of the automatic drive mechanism.

[0007] The automatic drive mechanism includes a drive motor and a transmission shaft. The drive motor is fixed on a fixed base. The transmission shaft is rotatably connected to the edge strip through a bearing. The output end of the drive motor is connected to the input end of the reducer. The output end of the reducer is fixedly connected to the transmission shaft. A drive arm is fixedly provided on the transmission shaft at the position corresponding to the main body of the knife switch. A connecting insulator is hinged between the end of the drive arm and the middle of the conductive knife switch. When the transmission shaft rotates, the drive arm and the connecting insulator drive the conductive knife switch to rotate around the hinge point of the contact assembly.

[0008] The conductive switch knife is symmetrically provided with bolt assemblies at one end away from the moving contact assembly. A clamp is sleeved on the outside of the bolt assembly, the clamp passes through the conductive switch knife, and a nut is screwed to the outside of the bolt assembly. A spring is provided between the nut and the clamp.

[0009] The intelligent control mechanism includes a housing, inside which are housed a PLC controller, a wireless communication module, an instruction receiving module, and a drive module. The PLC controller is the core control unit and is electrically connected to the wireless communication module, the instruction receiving module, and the drive module. The wireless communication module is used to establish communication with a remote monitoring center to achieve remote operation data transmission. The instruction receiving module is used to receive local and remote control instructions. The drive module is electrically connected to a drive motor and is used to receive control signals from the PLC controller to drive the stepper motor to start, stop, and rotate in both directions, achieving precise control of the opening and closing angle of the switch.

[0010] A status monitoring mechanism is provided on the outside of the main body of the disconnect switch. The status monitoring mechanism includes a displacement sensor and a temperature sensor. The displacement sensor is installed on the drive shaft to collect the rotation angle of the drive shaft and then calculate the opening and closing position of the disconnect switch. Three sets of temperature sensors are provided and installed on each set of stationary contact assembly and moving contact assembly respectively to monitor the temperature of the stationary contact assembly and moving contact assembly in real time.

[0011] The monitoring data from the displacement sensor and temperature sensor are transmitted to the PLC controller in real time, where the PLC controller processes and analyzes the data.

[0012] A paddle is provided at the end of the drive shaft away from the drive motor. A manual operating mechanism is connected to the outside of the paddle, and the manual operating mechanism is used to manually drive the drive shaft to rotate.

[0013] The manual operating mechanism includes a control component and a long shaft. The control component and the long shaft, as well as the long shaft and the paddle, are connected by hinges. The control component drives the paddle to move up and down via the long shaft, which in turn drives the transmission shaft to rotate.

[0014] The control assembly includes a front plate and a rear plate, which are fixedly connected by bolts at the corners. An arc-shaped plate is fixedly installed on the outer side of the front plate, and a control handle is hinged inside the arc-shaped plate. An inner frame is fixedly installed on the outer side of the rear plate, and an angle plate is hinged inside the inner frame. A connecting shaft is hinged between the lower side of the angle plate and the lower end of the control handle. The control handle can drive the angle plate to rotate around the hinge point with the inner frame through the connecting shaft. The upper side of the angle plate is hinged to the lower end of the long shaft hinge seat through a connecting fork. Multiple adjustment holes are provided on the angle plate near the connecting fork, and the position of the lower end of the connecting fork can be adjusted through the adjustment holes.

[0015] The arc-shaped plate has limit holes at the open and closed positions of the control handle. An automatic limiter is installed inside the control handle near the limit holes to limit the position of the control handle. The automatic limiter can be a component such as an electric pin structure or a telescopic motor structure.

[0016] Both ends of the long shaft are screwed with adjusting screws, and locking nuts are provided between the adjusting screws and the long shaft.

[0017] This invention provides an automatic opening and closing device for a 35kV isolating switch, which has the following advantages: This invention utilizes the coordinated operation of an intelligent control mechanism and an automatic drive mechanism. The PLC controller can precisely control the start, stop, and forward / reverse rotation of the drive motor. Combined with the deceleration effect of the reducer, the drive shaft rotates smoothly, which in turn drives the conductive switch to open and close precisely through the drive arm and connecting insulator. This effectively avoids problems such as incomplete closing and incomplete opening, improves operational accuracy and efficiency, reduces the labor intensity of operators, eliminates the need for on-site manual operation, and reduces safety hazards associated with working at heights.

[0018] A status monitoring mechanism is set up to collect the rotation angle of the drive shaft through a displacement sensor, calculate the opening and closing position of the knife switch, and monitor the operating status of the knife switch in real time. Temperature sensors monitor the temperature of the stationary contact assembly and the moving contact assembly in real time to detect abnormalities such as poor contact and overheating in a timely manner. After the monitoring data is processed and analyzed by the PLC controller, it is transmitted to the remote monitoring center through the wireless communication module, which facilitates remote real-time monitoring by staff, early prediction of equipment failures, and prevention of safety accidents.

[0019] A manual operation mechanism is provided. When the automatic drive mechanism fails, the operator can drive the long shaft and paddle to rotate through the control component, thereby driving the transmission shaft to rotate and realize the manual opening and closing of the knife switch. The adjustment hole of the angle plate in the control component can adjust the position of the connecting fork, and the adjustment screws at both ends of the long shaft can adjust the length of the long shaft to adapt to different installation scenarios. The limit hole of the arc plate works with the automatic limiter of the control handle to precisely limit the position of the control handle, ensuring the accuracy and safety of manual operation.

[0031] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.

[0032] Please see Figure 1-5 An automatic opening and closing device for a 35kV isolating switch includes a fixed base 1, a switch body 2, an automatic drive mechanism 3, and an intelligent control mechanism 4. The specific structure and connection relationship of each component are as follows: The fixed base 1 serves as the installation foundation for the entire device and includes symmetrically arranged side strips 101. The side strips 101 can be made of high-strength steel to ensure structural stability. The side strips 101 are symmetrically arranged with connecting plates 102, which are fixed between them by bolts or welding. The connecting plates 102 are used to install the post insulators 201 to fix the main body 2 of the switch.

[0033] The disconnector body 2 has three sets, adapting to the three-phase power supply requirements of a 35kV power system. All three sets of disconnector bodies 2 are installed symmetrically on the outer side of the edge strip 101 of the fixed base 1. Each set of disconnector bodies 2 includes a post insulator 201, a stationary contact assembly 2012, a moving contact assembly 2011, and a conductive switch 202. The post insulator 201 is vertically fixed to the outside of the connecting plate 102 and is made of ceramic material with excellent insulation properties, serving both insulation and support functions. The stationary contact assembly 2012 is bolted to the top of one set of post insulators 201, while the moving contact assembly 2011 is mounted on the top of the other set of post insulators 201. One end of the conductive switch 202 is hinged to the moving contact assembly 2011 via a hinge shaft, and the other end can engage or disengage from the stationary contact assembly 2012, thereby realizing the closing and opening of the conductive disconnector and ensuring excellent conductivity.

[0034] To achieve automatic opening and closing of the knife switch, an automatic drive mechanism 3 is provided. The automatic drive mechanism 3 is connected to the knife switch body 2 for transmission and is used to provide the power required for opening and closing the knife switch. The automatic drive mechanism 3 includes a drive motor 301 and a transmission shaft 302. The drive motor 301 can be a stepper motor, fixed on the connecting plate 102 of the fixed base 1. The transmission shaft 302 is rotatably connected to the edge strip 101 through a bearing. The bearing is a sealed bearing to prevent dust and rainwater from entering and extend its service life. The output end of the drive motor 301 is connected to the input end of the reducer 3011 through a coupling. The output end of the reducer 3011 is fixedly connected to the transmission shaft 302 through a flat key. The reducer 3011 can reduce the speed of the drive motor 301 and increase the output torque to ensure smooth and powerful opening and closing of the knife switch. A drive arm 3021 is fixedly installed on the transmission shaft 302 at the position corresponding to each group of knife switch bodies 2. The end of the drive arm 3021 and the middle of the conductive knife switch 202 are hinged to a connecting insulator 3022 through a hinge shaft. The connecting insulator 3022 plays the role of insulation and transmission. When the drive shaft 302 rotates, it drives the drive arm 3021 to swing. The drive arm 3021 drives the conductive switch 202 to rotate around the hinge point of the contact assembly 2011 through the connecting insulator 3022, thereby realizing the automatic opening and closing of the switch.

[0035] like Figure 6As shown, to improve the stability of the connection between the conductive switch 202 and the stationary contact assembly 2012, bolt assemblies 2021 are symmetrically arranged at the end of the conductive switch 202 away from the moving contact assembly 2011. A clamping piece 2022 is sleeved on the outside of the bolt assembly 2021, passing through the conductive switch 202. A nut is screwed onto the outside of the bolt assembly 2021, and a spring 2023 is arranged between the nut and the clamping piece 2022. When the conductive switch 202 is engaged with the stationary contact assembly 2012, the spring 2023 is compressed, generating elastic force on the clamping piece 2022, causing the clamping piece 2022 to tightly clamp the stationary contact assembly 2012, avoiding problems such as poor contact or loosening. It also acts as a buffer, reducing the impact force during closing.

[0036] The intelligent control mechanism 4 is electrically connected to the automatic drive mechanism 3, and is used to receive remote control commands or local trigger signals to control the action of the automatic drive mechanism 3. The intelligent control mechanism 4 includes a housing 401, which is made of waterproof, dustproof, and corrosion-resistant metal to protect the internal electronic components. Inside the housing 401, there is a PLC controller, a wireless communication module, an instruction receiving module, and a drive module. The PLC controller is the core control unit and uses a programmable logic controller to realize the automated control of the entire device. It is electrically connected to the wireless communication module, the instruction receiving module, and the drive module through wires. The wireless communication module can be a 4G / 5G module, used to establish wireless communication with the remote monitoring center to realize the transmission of remote operating data such as the opening and closing position of the disconnect switch and the contact temperature, and to receive remote control commands. The instruction receiving module is used to receive local control commands such as on-site button triggers and remote control commands, and transmit the commands to the PLC controller. The drive module is electrically connected to the drive motor 301, and is used to receive control signals from the PLC controller to drive the stepper motor to start, stop, and rotate forward and backward, so as to realize precise control of the opening and closing angle of the disconnect switch and ensure that the closing and opening are in place.

[0037] In this embodiment, during remote automatic operation, the remote monitoring center sends control commands to the PLC controller via the wireless communication module, or the operator sends control commands via the local trigger command receiving module. The command receiving module transmits the commands to the PLC controller, and the PLC controller controls the drive module to operate according to the commands. The drive module drives the drive motor 301 to start, stop, and rotate in both directions. After being reduced in speed by the reducer 3011, the drive motor 301 drives the transmission shaft 302 to rotate. The transmission shaft 302 drives the conductive switch 202 to rotate around the hinge point of the contact assembly 2011 through the drive arm 3021 and the connecting insulator 3022, thereby realizing the automatic closing or opening of the switch.

[0038] like Figure 2-3As shown, in another embodiment, to monitor the operating status of the disconnect switch in real time, a status monitoring mechanism 5 is provided on the outside of the disconnect switch body 2. The status monitoring mechanism 5 includes a displacement sensor 502 and a temperature sensor 501. The displacement sensor 502 can be an angular displacement sensor, installed on the drive shaft 302, to collect the rotation angle of the drive shaft 302. The PLC controller converts the rotation angle into the opening and closing position of the disconnect switch according to a preset conversion formula, thereby monitoring the operating status of the disconnect switch in real time. The temperature sensor 501 can be an infrared temperature sensor, with three sets installed at the connection between each set of stationary contact assembly 2012 and moving contact assembly 2011, to monitor the temperature of the stationary contact assembly 2012 and moving contact assembly 2011 in real time. When the temperature exceeds a preset threshold, the PLC controller issues an alarm signal and transmits it to the remote monitoring center via a wireless communication module, reminding staff to handle the situation promptly. The monitoring data from the displacement sensor 502 and the temperature sensor 501 are transmitted to the PLC controller in real time, where the PLC controller processes and analyzes the data to achieve real-time monitoring and early warning of abnormalities in the equipment's operating status.

[0039] In this embodiment, the displacement sensor 502 collects the rotation angle of the drive shaft 302 and calculates the opening and closing position of the knife switch. The temperature sensor 501 monitors the temperature of the stationary contact assembly 2012 and the moving contact assembly 2011. The monitoring data is transmitted to the PLC controller in real time. After processing and analysis, it is transmitted to the remote monitoring center through the wireless communication module to realize real-time monitoring of the equipment's operating status.

[0040] like Figure 7-10 As shown, in another embodiment, to address the possibility of a malfunction in the automatic drive mechanism 3, a lever 3023 is provided at the end of the drive shaft 302 away from the drive motor 301. The lever 3023 is fixedly connected to the drive shaft 302 by bolts. A manual operating mechanism 6 is externally connected to the lever 3023. The manual operating mechanism 6 is used to manually drive the drive shaft 302 to rotate, thereby manually opening and closing the knife switch. The manual operating mechanism 6 includes a control component 601 and a long shaft 602. The control component 601 is connected to the long shaft 602, and the long shaft 602 is connected to the lever 3023 by a hinge seat 603. The control component 601 drives the lever 3023 to move up and down through the long shaft 602, thereby driving the drive shaft 302 to rotate, thus manually opening and closing the knife switch.

[0041] The control assembly 601 includes a front plate 6011 and a rear plate 6014, which are fixedly connected by bolts at the corners to form a stable mounting base. An arc-shaped plate 6012 is fixedly mounted on the outer side of the front plate 6011. The curvature of the arc-shaped plate 6012 matches the swing trajectory of the control handle 6013. The control handle 6013 is hinged to the inside of the arc-shaped plate 6012 via a hinge shaft. The control handle 6013 can be made of insulating material to ensure operator safety. An inner frame 6015 is fixedly mounted on the outer side of the rear plate 6014. An angle disc 6016 is hinged to the inside of the inner frame 6015 via a hinge shaft. The lower side of the angle disc 6016 is connected to the lower side of the control handle 6013. A connecting shaft 6017 is provided between the ends via a hinge shaft. When the operator swings the control handle 6013, the control handle 6013 drives the angle disk 6016 to rotate around the hinge point with the inner frame 6015 via the connecting shaft 6017. The upper side of the angle disk 6016 is hinged to the hinge seat 603 at the lower end of the long shaft 602 via a connecting fork 6018. Multiple adjustment holes 6019 are provided near the connecting fork 6018 on the angle disk 6016. The adjustment holes 6019 are evenly distributed. By fixing the lower end of the connecting fork 6018 in different adjustment holes 6019, the position of the lower end of the connecting fork 6018 can be adjusted, thereby adjusting the transmission angle of the long shaft 602 to adapt to different installation scenarios.

[0042] Both ends of the long shaft 602 are screwed with adjusting screws 6021. A locking nut 6022 is provided between the adjusting screw 6021 and the long shaft 602. By rotating the adjusting screw 6021, the overall length of the long shaft 602 can be adjusted to adapt to different installation distances. After adjustment, tighten the locking nut 6022 to fix the position of the adjusting screw 6021 and ensure the transmission stability of the long shaft 602.

[0043] In this embodiment, when the automatic drive mechanism 3 malfunctions, the operator can perform manual operation: swing the control handle 6013, which drives the angle disk 6016 to rotate via the connecting shaft 6017. The angle disk 6016 drives the long shaft 602 to move via the connecting fork 6018. The long shaft 602 drives the paddle 3023 to move up and down, thereby driving the transmission shaft 302 to rotate, realizing the manual opening and closing of the knife switch. When the control handle 6013 swings to the open or closed position, the automatic limiter 60122 engages in the limit hole 60121 to limit the control handle 6013 and ensure that the operation is in place.

[0044] This invention has a reasonable structure and is easy to operate. It realizes automatic and precise opening and closing, intelligent real-time monitoring and manual emergency operation of 35kV isolating switches, effectively solves the defects of existing technologies, and improves the safety and stability of power system operation.
