Description

Technical Field

[0001] The invention relates to the technical field of conductive connection devices, and in particular to an isolation insulating cover and an isolation switch device. Background Art

[0002] In the stable operation of the power system, high-voltage disconnectors play a key role, and their safe and reliable operation is crucial to the normal power supply of the entire power network and the safety of equipment and personnel. However, the existing high-voltage disconnector technology faces a series of severe challenges in actual application scenarios.

[0003] Traditional high-voltage disconnectors lack effective insulation protection improvement measures. In complex and changeable operating environments, such as humid environments, areas with corrosive gases or dust, disconnectors are easily corroded by external factors. Disconnectors that lack good insulation protection may gradually reduce their insulation performance, leading to an increased risk of leakage, which not only threatens the personal safety of operators, but may also cause serious faults such as phase-to-phase short circuits, affecting the stability of the power system, causing large-scale power outages, and causing huge losses to social production and life.

[0004] Phase sequence identification is a basic and important task in power operation, but most of the existing high-voltage disconnectors do not have an intuitive and effective phase sequence identification method. Operators often find it difficult to accurately determine the line phase sequence when performing operations such as equipment installation and power restoration after maintenance. Especially in complex power wiring environments, it is very easy to make mistakes based on experience or traditional marking methods. Phase sequence errors can lead to a series of catastrophic consequences. For example, the reversal of equipment such as motors may cause damage to mechanical parts, and in severe cases, even cause failure of the entire production system; in the grid-connected operation of the power system, inconsistent phase sequences will cause huge impact currents, damage electrical equipment, undermine the stability of the power grid, and affect the quality and reliability of power supply.

[0005] In addition, in the operation of high-voltage disconnectors, timely detection of potential faults is crucial to ensure safe and stable operation of the system. Current technical means have obvious deficiencies in fault monitoring and early warning. Operators can usually only rely on regular inspections to discover problems, which is not only inefficient but also difficult to capture sudden faults in time. For example, abnormal conditions such as partial discharge and overheating inside the disconnector may gradually develop into serious faults during the inspection interval. Due to the lack of real-time monitoring and early warning mechanisms, timely measures cannot be taken, resulting in the expansion of faults, increased equipment maintenance costs, and prolonged power outages, which brings great inconvenience to users and also has a serious impact on the overall operation of the power system.

[0006] Furthermore, as the power system develops towards intelligence, the existing high-voltage disconnectors are difficult to meet the needs of intelligent monitoring and management. The inability to achieve effective communication and data interaction with external systems makes it difficult for operation and maintenance personnel to remotely grasp the operating status of the equipment in real time, which is not conducive to centralized and intelligent management and optimized scheduling of the power system. Summary of the invention

[0007] The purpose of the present invention is to provide an isolation insulation cover and an isolating switch device, wherein the insulating shell and the insulating cavity provide insulation protection to ensure the safe and stable operation of the isolating switch and protect it from interference from external factors, and the light board emits light according to the phase sequence of the busbar, which is convenient for operators to identify the phase sequence and improve the accuracy and efficiency of operation, especially in special environments. The magnetic flux component monitors the magnetic flux, and when an abnormality occurs, the control component can transmit a fault signal to an external terminal and cause the light board to flash for warning, so that hidden dangers can be discovered in time, system safety can be guaranteed, the intelligence level of equipment can be improved, and remote monitoring and management are beneficial, which is of great significance to the safe and efficient operation of the power system.

[0008] The present invention is achieved through the following technical solutions:

[0009] An isolation insulation cover, comprising:

[0010] An insulating housing, wherein a first insulating cavity for accommodating the disconnector is disposed inside the insulating housing, second insulating cavities for connecting the busbar are disposed at both ends of the first insulating cavity, and a magnetic flux component for detecting magnetic flux is disposed on the inner wall of the first insulating cavity;

[0011] A control assembly, the control assembly is connected to the outer side wall of the insulating housing, and the control assembly is provided with a light plate, and the light plate can emit light of different colors according to the phase sequence of the busbar;

[0012] When the magnetic flux component detects that the magnetic flux in the first insulating cavity is abnormal, it will send an abnormal electrical signal to the control component, and the control component will transmit the fault signal to an external terminal and control the light panel to emit flashing light.

[0013] In this solution, the insulating shell and the internal insulating cavity structure provide reliable insulation protection for the disconnector, effectively preventing the risk of electric shock and the adverse effects of external environmental factors on the disconnector, and ensuring stable operation of the equipment. The function of the light board to emit different colors of light according to the phase sequence of the busbar greatly facilitates the operator to accurately identify the phase sequence, avoid a series of problems caused by phase sequence errors, and improve operational accuracy and efficiency, especially at night or in poor lighting. At the same time, the flux component's monitoring of magnetic flux and fault signal transmission and the light board flashing warning mechanism can detect potential fault hazards in real time, promptly notify operation and maintenance personnel and warn on-site operators, reduce fault risks and losses, and at the same time improve the intelligence of the equipment, assist in remote monitoring and management, and lay a solid foundation for the safe, efficient and intelligent operation of the power system.

[0014] As a further technical solution for the isolation insulating cover, the magnetic flux assembly includes a magnetoresistive sensor, and the magnetoresistive sensor is arranged on the inner wall surface of the first insulating cavity.

[0015] In this solution, the magnetoresistive sensor is highly sensitive to changes in the magnetic field and accurately detects the magnetic flux in the first insulating cavity, providing accurate data for judging the operating status of the disconnector. Its non-contact detection characteristics do not interfere with the normal operation of the disconnector, and avoid self-wear, ensuring long-term stable monitoring. Once the magnetic flux is abnormal, it can quickly feedback to the control component to achieve timely fault warning, help operation and maintenance personnel respond quickly, and reduce the risk of equipment damage and power outages.

[0016] As a further technical solution for the isolation insulating cover, the magnetic flux component includes a multi-turn magnetic flux coil, which is surrounded by the inner wall of the first insulating cavity with the isolation switch as the center. The identification component arranged in the magnetic flux component detects the induced current generated in the magnetic flux coil and stores the induced current generated by the magnetic flux coil in the power storage component.

[0017] In this solution, the flux coil surrounds the inner wall of the first insulating cavity with the isolating switch as the center. This layout can effectively enhance the sensing ability of magnetic field changes, thereby accurately monitoring the working status of the isolating switch. When the operating state of the isolating switch changes and causes the magnetic field to change, the flux coil will generate an induced current, which will be detected by the identification component and stored in the power storage component. On the one hand, this realizes the recycling of energy, supplies power to some functions of the device, and improves energy utilization to a certain extent; on the other hand, through the analysis of the induced current, the performance changes of the isolating switch can be further understood, providing data support for fault diagnosis and equipment maintenance, ensuring the safe and stable operation of the power system, and at the same time embodies the design concept of energy saving and intelligent monitoring, and improves the overall performance of the entire isolation insulation cover and related equipment.

[0018] As a further technical solution of the isolation insulating cover, the first insulating cavity is a closed cavity, and the first insulating cavity is filled with insulating gas.

[0019] In this solution, the closed structure effectively prevents external dust, moisture, corrosive gases and other impurities from entering the cavity, avoiding erosion and pollution of the disconnector and internal components, greatly extending the service life of the equipment and ensuring its long-term stable operation. Secondly, the insulating gas has excellent insulation performance. Compared with ordinary air, it can significantly improve the insulation strength in the cavity, effectively prevent the occurrence of electrical breakdown, greatly reduce the risk of faults such as phase-to-phase short circuit and leakage, and provide a solid and reliable guarantee for the safe and stable operation of the disconnector. Furthermore, the insulating gas is evenly distributed in the cavity, which can effectively fill various tiny gaps, make the electric field distribution more uniform, further optimize the insulation effect, and enhance the stability of the entire insulation system. In addition, this design can also suppress the generation and development of internal arcs to a certain extent. Even if an arc occurs in an abnormal situation, the insulating gas can quickly extinguish the arc, reduce the damage of the arc to the equipment, reduce the equipment maintenance cost, and improve the reliability and safety of the power system operation.

[0020] As a further technical solution of the isolation insulating cover, a connection assembly is arranged in the second insulating cavity, and the connection assembly includes a conductive plate, an upper clamping seat and a lower clamping seat;

[0021] The conductive plate is respectively connected to the two ends of the first insulating cavity, the upper clamping seat and the lower clamping seat are arranged above and below the inner end of the conductive plate to form a clamping assembly for clamping the isolating switch, and the outer end of the conductive plate is electrically connected to the busbar.

[0022] In this solution, the conductive plates are connected to both ends of the first insulating cavity, respectively, to construct an electrical path between the busbar and the disconnector, ensuring that electric energy can be transmitted efficiently and stably, and guaranteeing the normal power supply process of the power system. The clamping assembly formed by the upper clamping seat and the lower clamping seat on the inner side of the conductive plate accurately and firmly clamps the disconnector, which not only ensures good electrical contact, reduces contact resistance, reduces energy loss and heat generation, but also effectively fixes its position during the disconnector opening and closing operations, preventing problems such as poor contact due to vibration or displacement, and improving the reliability and safety of the operation.

[0023] As a further technical solution for the isolation insulating cover, a pair of mounting seats are also provided on the insulating shell, and the mounting seats are bolted to the external device through mounting holes.

[0024] In this solution, the mounting seats arranged in pairs on the insulating shell are connected to the external equipment bolts through the mounting holes. This connection method provides a stable and reliable installation method for the isolation insulation cover, ensuring that it is fixed in position during use and will not be displaced or loosened due to external factors (such as vibration, wind, etc.), thereby ensuring the relative position between the isolation insulation cover and the isolation switch is stable, maintaining its effective protection and functional support for the isolation switch.

[0025] As a further technical solution of the isolation insulating cover, the second insulating cavity is a closed cavity, and the second insulating cavity is filled with insulating gas. The connecting component also includes a terminal block, and the terminal block is provided with a through hole. The busbar is crimped into the through hole by a tightening screw.

[0026] In this solution, the presence of the closed cavity and insulating gas further enhances the insulation performance, effectively blocks the influence of external environmental factors on the connection parts, prevents the degradation of insulation performance and electrical failures caused by moisture, dust, etc., and ensures the stability and safety of the connection between the busbar and the disconnector; and the crimping method of the terminal block and its through hole in conjunction with the clamping screw realizes a tight and reliable connection between the busbar and the connection assembly.

[0027] A disconnect switch device comprises a conductive moving contact assembly and an isolation insulating cover, wherein the conductive moving contact assembly comprises a relatively sliding conductive rod, the ends of which are connected to conductive moving contacts, and when a driving motor drives the conductive rod to slide to both sides, the conductive moving contacts are clamped and conducted by the clamping assemblies located at both ends of a first insulating cavity.

[0028] In this solution, the conductive moving contact assembly realizes the conduction and disconnection control of the isolating switch. The driving motor drives the conductive sliding rod to slide relative to each other, driving the conductive moving contact to move, so that it can accurately cooperate with the clamping components at both ends of the first insulating cavity to achieve reliable clamping conduction. This design ensures good electrical connection in the conduction state, ensures efficient transmission of electric energy, and reduces energy loss and faults caused by poor contact. During the disconnection operation, the circuit can be quickly cut off, the power supply can be effectively isolated, and safety accidents caused by accidental power supply can be prevented. At the same time, this solution improves the degree of automation of the isolating switch operation, reduces the uncertainty and labor intensity of manual operation, and improves operating efficiency. Combined with the isolation insulation cover, the performance of the entire device is further enhanced, enabling it to operate stably in the power system, improve the reliability of power distribution and control, ensure the continuity and safety of power supply, and meet the requirements of modern power systems for efficient, safe and intelligent operation.

[0029] As a further technical solution of the isolating switch device, the conductive moving contact assembly includes a slide rail, a first conductive sliding rod, a first conductive moving contact, a second conductive sliding rod and a second conductive moving contact;

[0030] Slideways are respectively provided at both ends of the slide rail, one side end of the first conductive slide rod is slidably connected to the slideway, one side end of the second conductive slide rod is slidably connected to the other slideway, and driving gears are provided between the first conductive slide rod and the second conductive slide rod and are respectively meshed. When the driving motor drives the driving gear, the first conductive slide rod and the second conductive slide rod slide in opposite directions respectively, so that the first conductive moving contact and the second conductive moving contact are respectively clamped and connected by the clamping assemblies located at both ends of the first insulating cavity.

[0031] In this solution, the slide rail and the slideway provide a stable and precise sliding path for the first conductive slide rod and the second conductive slide rod, ensuring that they maintain linear motion during the action process, so that the conductive moving contact can accurately dock with the clamping assembly to achieve reliable conduction. The meshing transmission mode of the drive gear and the two conductive slide rods realizes efficient power transmission, so that the first conductive slide rod and the second conductive slide rod can slide smoothly and synchronously in opposite directions under the action of the drive motor, ensuring the consistency and coordination of the actions of the first conductive moving contact and the second conductive moving contact. This precise motion control not only improves the accuracy of the conduction and disconnection operation of the disconnector, but also reduces the arc, overheating and other problems caused by poor contact of the contacts, prolongs the service life of the contacts, and reduces the maintenance cost of the equipment. At the same time, the structural design is easy to realize automatic control, and the opening and closing operation of the disconnector can be easily realized by the forward and reverse rotation of the drive motor, which improves the operating efficiency, reduces the possibility of manual operation errors, enhances the reliability and stability of the disconnector device in the power system, and effectively guarantees the safe and efficient operation of the power system.

[0032] As a further technical solution of the isolating switch device, the first conductive moving contact and the second conductive moving contact are both L-shaped, and the lengths of the first conductive moving contact and the second conductive moving contact are greater than the spacing of the slideways.

[0033] In this solution, the L-shaped structure increases the contact area between the contact and the clamping assembly, making the electrical connection more reliable in the on state, effectively reducing contact resistance, reducing energy loss and heat generation, thereby improving the efficiency of power transmission, while reducing the risk of local overheating due to poor contact, extending the service life of the contact, and enhancing the stability of equipment operation. The contact length is greater than the slide spacing, ensuring that during the process of the drive motor driving the conductive slide rod to slide, even if there is a certain position deviation or jitter, the contact can always maintain good contact with the clamping assembly, thereby improving the adaptability and fault tolerance of the isolating switch device to different working conditions, and further ensuring the stability of conduction. During the disconnecting operation, the special shape of the L-shaped contact is conducive to quickly disengaging from the clamping assembly, reducing the arcing time, reducing the damage of the arc to the contacts and equipment, and improving the safety and reliability of the disconnecting operation, providing strong support for the safe and stable operation of the power system.

[0034] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0035] 1. The first insulating cavity and the second insulating cavity in the present invention respectively provide targeted insulation protection for the disconnector and the busbar connection part. Compared with the prior art, this partitioned insulation design can more effectively prevent electric field concentration and make the electric field distribution more uniform, thereby greatly improving the insulation reliability;

[0036] 2. The light board on the control assembly of the present invention can emit light of different colors according to the phase sequence of the busbar, providing an intuitive and clear phase sequence identification method for operators, avoiding equipment damage and power accidents caused by wrong phase sequence;

[0037] 3. After receiving the abnormal signal, the control component of the present invention can not only transmit the fault signal to the external terminal, which is convenient for the operation and maintenance personnel to remotely monitor and take timely measures, but also control the light board to emit flashing light to warn the operator on site. This dual warning method ensures that the fault information can be conveyed to the relevant personnel in a timely manner, effectively reduces the risk of equipment damage and power outage caused by the failure to discover the fault in time, and improves the reliability and safety of the power system;

[0038] 4. The present invention can monitor the changes in magnetic flux in the first insulating cavity in real time through a magnetoresistive sensor or a multi-turn magnetic flux coil. Once an abnormality occurs inside the isolating switch, such as partial discharge, overheating, etc., which causes a change in the magnetic field, the magnetic flux component can quickly detect it and send the abnormal signal to the control component; this real-time monitoring capability has higher timeliness and accuracy than the existing technology, and can promptly discover potential fault hazards.

DETAILED DESCRIPTION

[0048] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with embodiments and drawings. The exemplary embodiments of the present invention and their description are only used to explain the present invention and are not intended to limit the present invention.

[0049] Example 1

[0050] This embodiment 1 provides an isolation insulating cover, such as Figure 1-Figure 3 As shown, the isolation insulation cover of the present invention comprises an open rectangular parallelepiped insulation shell 2 with a through middle made of solid insulating material glass fiber reinforced plastic and a control component 3;

[0051] Among them, see Figure 1-Figure 3As shown, the insulating housing 2 is also provided with a pair of mounting seats 5, which are bolted to the external device through the mounting holes 6, so that the isolation insulating cover can be firmly installed with the external device, and the interior of the insulating housing 2 is provided with a first insulating cavity 15 for accommodating the disconnector, and steps are respectively provided at both ends of the first insulating cavity 15, and the conductive plate 8 is bolted to the steps, so that a second insulating cavity 16 for connecting the busbar 1 is formed at both ends of the first insulating cavity 15. At the same time, a magnetic flux component for detecting magnetic flux is provided on the inner wall surface of the first insulating cavity 15, and the magnetic flux component includes a multi-turn magnetic flux The coil 14, the magnetic flux coil 14 is surrounded on the inner wall surface of the first insulating cavity 15 with the isolating switch as the central axis. When the operating state of the isolating switch changes and causes the magnetic field to change, the magnetic flux coil 14 will generate an induced current. The identification component 11 provided in the magnetic flux component detects the induced current generated in the magnetic flux coil 14 and stores the induced current generated by the magnetic flux coil 14 in the power storage component 12. Of course, in this embodiment, a magnetoresistive sensor can also be connected to the inner wall surface of the first insulating cavity 15. The magnetoresistive sensor has a fast response speed to the magnetic field change, and can monitor the dynamic changes of the magnetic field in real time.

[0052] Among them, see Figure 1-Figure 4 As shown, a connecting assembly is arranged in the second insulating cavity 16, and the connecting assembly includes a terminal block 7, an upper clamping seat 9 and a lower clamping seat 10. The upper clamping seat 9 and the lower clamping seat 10 are arranged above and below the inner end of the conductive plate 8 to form a clamping assembly for clamping the isolating switch. The contact parts of the upper clamping seat 9 and the lower clamping seat 10 with the isolating switch are elastic sheets with conductive ability, which provide clamping force for the clamping assembly. The outer end of the conductive plate is connected to the terminal block 7, and a through hole is arranged on the terminal block 7. The busbar 1 is crimped into the through hole by a tightening screw to achieve electrical connection between the isolating switch and the busbar 1.

[0053] Please refer to Figure 1-Figure 3 As shown, the control component 3 is connected to the outer wall of the insulating shell 2, the identification component 11 and the power storage component 12 are both located inside the control component 3, and the outer wall of the control component 3 is electrically connected to a light board 4, which can emit light of different colors according to the phase sequence of the busbar 1. Here, when the light board 4 is installed, the color light of the light board 4 can be manually adjusted by manually identifying the phase sequence of the busbar 1. When the identification component 11 detects an abnormal magnetic flux in the first insulating cavity 15, that is, the induced current value is abnormal, an abnormal electrical signal will be sent to the control component 3, and the control component 3 will transmit the fault signal to the external terminal and control the light board 4 to emit a flashing light, so that potential fault hazards can be discovered in real time, the operation and maintenance personnel can be notified in time, and the on-site operators can be warned, thereby reducing the risk of faults and losses.

[0054] Example 2

[0055] In order to optimize the insulation effect, this embodiment provides another isolation insulation cover based on the technical solution of embodiment 1, such as Figure 1-Figure 4As shown, the first insulating cavity 15 is a closed cavity, and the first insulating cavity 15 is filled with insulating gas, such as sulfur hexafluoride or trifluoroiodomethane or a mixed gas. The excellent insulating properties of the insulating gas can significantly improve the insulation strength in the cavity compared to ordinary air, and effectively prevent the occurrence of electrical breakdown.

[0056] To further optimize the insulation effect, the second insulation cavity 16 is also a closed cavity. Both ends of the second insulation cavity 16 are sealed and connected by a cover plate, and the second insulation cavity 16 is also filled with insulating gas to ensure the stability and safety of the connection between the busbar 1 and the disconnector.

[0057] Example 3

[0058] This embodiment 3 provides an isolating switch device, such as Figure 5-Figure 6 As shown, it includes a conductive moving contact assembly 17 and the isolating insulating cover described in Example 1 or Example 2, the conductive moving contact assembly 17 is connected to the inner wall of the first insulating cavity 15 through a connecting column 26, the conductive moving contact assembly 17 is suspended in the middle of the first insulating cavity 15, and the conductive moving contact assembly 17 includes a relatively sliding conductive sliding rod, and the ends of the conductive sliding rod are connected to conductive moving contacts. When the driving motor 23 drives the conductive sliding rod to slide to both sides, the conductive moving contacts are clamped and connected by the clamping assemblies located at both ends of the first insulating cavity 15.

[0059] Specifically, see Figure 5-Figure 6 As shown, the conductive moving contact assembly 17 includes a slide rail 18, a first conductive slide rod 19, a first conductive moving contact 20, a second conductive slide rod 24 and a second conductive moving contact 25. Slideways 21 are respectively arranged at both ends of the slide rail 18. One side end of the first conductive slide rod 19 is slidably connected to the slideway 21. One side end of the second conductive slide rod 24 is slidably connected to the other slideway 21. A driving gear 22 is arranged between the first conductive slide rod 19 and the second conductive slide rod 24 and they are respectively meshed. The output end of the driving motor 23 passes through the insulating housing 2 and is sealed and connected to the insulating housing 2 through the sealed bearing 13. When the driving motor 23 drives the driving gear 22, the first conductive slide rod 19 and the second conductive slide rod 24 slide in opposite directions respectively, so that the first conductive moving contact 20 and the second conductive moving contact 25 are respectively clamped and connected by the clamping assemblies located at both ends of the first insulating cavity 15.

[0060] At the same time, the above-mentioned first conductive moving contact 20 and the second conductive moving contact 25 are both L-shaped, and the length of the first conductive moving contact 20 and the second conductive moving contact 20 is greater than the spacing of the slide 21. During the disconnecting operation, the L-shaped contact is conducive to quickly disengaging from the clamping assembly, reducing the arcing time, reducing the damage of the arc to the contacts and equipment, and improving the safety and reliability of the disconnecting operation.

[0061] When in use, first connect the isolating insulating cover to the pole through the mounting base 5, then manually identify the phase sequence and set the corresponding color for the light board 4. After the setting is completed, connect the busbar 1 to the terminal blocks 7 at both ends of the insulating shell 2, and then send a forward signal to the control component 3 through the remote control device to make the drive motor 23 rotate forward and drive the electric contact to move toward the clamping component, so that the isolating switch and the busbar 1 are connected. When isolation is required, send a reverse signal to the control component 3 through the remote control device to reverse the drive motor 23 and drive the electric contact away from the clamping component, so that the isolating switch and the busbar 1 are disconnected. When the isolating switch has poor contact, the contact resistance between the contacts will increase significantly, and the reduction of the current will cause the magnetic flux to decrease, or the insulation failure of the isolating switch will generate a huge short-circuit current that will cause the magnetic flux to increase. Therefore, when the identification component 11 detects that the induced current generated in the flux coil 14 exceeds the normal range, the fault signal will be transmitted to the external terminal and the light board will be controlled to emit a flashing light for prompting.

[0062] The specific implementation methods described above further illustrate the objectives, technical solutions and beneficial effects of the present invention in detail. It should be understood that the above description is only a specific implementation method of the present invention and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
