Description

Technical Field

[0001] This invention relates to the field of high-voltage switch technology, and specifically to an outdoor high-voltage disconnect switch. Background Technology

[0002] High-voltage switchgear plays a crucial role in circuit control and safety isolation in power systems. Among them, high-voltage disconnect switches, as a basic component, are mainly used for circuit disconnection and closure operations under no-load conditions to ensure the safety of equipment maintenance and repair processes.

[0003] However, existing outdoor high-voltage disconnect switches have revealed numerous technical defects in actual operation, severely impacting equipment reliability and service life. During contact operation, as the switch begins to separate from a fully closed state, the contact pressure and the number of effective contact points gradually decrease, leading to a continuous increase in contact resistance. This increased resistance causes a sharp concentration of current density in local contact areas, generating a significant Joule heating effect, which in turn triggers localized melting of the metal material, forming unstable molten metal droplets. After long-term operation, the contact surface becomes rough and uneven due to repeated melting and cooling, significantly reducing the actual conductive contact area. This not only weakens current transmission capacity but also easily causes severe contact wear, weld adhesion, and other faults. Once the contact surface wear reaches a critical level, it will directly lead to an abnormally high contact resistance, decreased connection stability, and even insufficient engagement between the stationary and moving contacts, potentially inducing high-voltage switchgear system failures or safety accidents, threatening the safe operation of the power grid.

[0004] Meanwhile, the existing conductor connection structure of outdoor high-voltage disconnect switches has significant limitations. Their high-voltage conductor joints generally use a fixed screw-locking design, which cannot flexibly adapt to the needs of conductor connections in different directions. In actual engineering installations, high-voltage conductors often need to be forcibly bent to match the joint direction. This unnatural bending not only damages the internal structure of the conductor, reducing its mechanical strength and conductivity, but also causes stress concentration, leading to loosening or detachment of the connection points, further exacerbating the risk of poor contact and affecting the overall operational stability and safety of the disconnect switch. These problems are particularly prominent under complex outdoor environmental conditions, urgently requiring structural innovation to improve the durability and installation adaptability of the equipment. Summary of the Invention

[0005] The purpose of this invention is to solve the problems of increased contact resistance and unstable connection caused by contact wear, and to propose an outdoor high-voltage disconnect switch.

[0006] The objective of this invention can be achieved through the following technical solutions: An outdoor high-voltage disconnect switch, comprising: An isolation base is used to fix and install the disconnect switch. Two sets of insulating supports are fixedly installed on the isolation base. A connecting contact is fixedly installed on an insulating support. One end of the connecting contact is provided with a terminal for connecting to a high-voltage wire, and the other end is fixedly provided with a switch bracket for installing a switch knife. A switch knife has one end rotatably mounted on a knife knife bracket of one set of connecting contacts, and the other end is in contact with or separated from another set of connecting contacts to achieve switch on / off control. The switch includes two sets of knife plates arranged side by side. The two sides of the two sets of knife plates are connected by a knife shaft, and one set of knife shafts is rotatably mounted on a knife support. A knife shaft spring for adjusting the distance between the two sets of knife plates is sleeved on the knife shaft. Two knife contact plates are provided on the opposite surfaces of the two sets of knife plates. The knife contact plates contact the connecting contact head to realize circuit conduction. The knife contact plates are made of wear-resistant conductive material. A knife lock for locking the latch is provided between the two sets of knife plates.

[0007] Preferably, the knife gate lock includes a first pin and a second pin fixedly installed between two sets of knife gate plates. A limiting hook for locking the hook at the lower end of the connecting contact is rotatably installed on the first pin. An unlocking frame for controlling the rotation of the first pin to unlock is rotatably installed on the second pin. Both the first pin and the second pin are fitted with a pin torsion spring. One end of the pin torsion spring is connected to the knife gate plate, and the other end of the pin torsion spring is connected to the limiting hook and the unlocking frame. The limiting hook and the unlocking frame are both made of insulating material.

[0008] Preferably, the connecting contact includes a horizontal connecting plate fixedly mounted on an insulating support. The horizontal connecting plate is provided with a through hole for installing a terminal block. One end of the horizontal connecting plate is fixedly provided with a trigger vertical plate that contacts the switch plate. The trigger vertical plate is provided with a retractable contact mechanism. The retractable contact mechanism can extend and abut against the switch plate when the switch plate is closed to achieve conductivity, reducing the friction between the switch plate and the contact during rotation, which would otherwise cause wear and reduce the connection stability of the contact.

[0009] Preferably, the trigger vertical plate is provided with a vertical plate mounting groove for mounting the contact plate mechanism. The contact plate mechanism includes two sets of contact plate slides symmetrically slidably disposed in the vertical plate mounting groove. A conductive contact plate that is electrically connected to the switch contact plate is fixedly disposed at one end of the contact plate slide near the outer side of the trigger vertical plate. The conductive contact plate is slidably connected through the side wall of the trigger vertical plate. The trigger vertical plate is provided with a connecting groove on the side away from the terminal block. The connecting groove is connected to the vertical plate mounting groove. A trigger pin is slidably provided at the connecting groove. Two sets of driving rods are rotatably connected to the trigger pin. The ends of the two sets of driving rods away from the trigger pin are rotatably connected to the touch plate slide on the same side through the connecting pin. The switch knife is provided with a trigger rod for driving the trigger pin to slide downward. A contact spring is fixedly installed between the two sets of contact plate slides. When the conductive contact plate extends outward, the contact spring is in a stretched state. When the switch knife rotates downwards to close, the trigger linkage contacts the trigger pin during rotation, which then drives the trigger pin to move downwards. Simultaneously, the downward movement of the trigger pin drives two sets of drive linkages to rotate downwards, causing the conductive contact plates on both sides to slide outwards synchronously, thus contacting the knife contact plate on the switch knife and completing the conductive contact. When the switch knife rotates upwards to disconnect the conductivity, the trigger linkage separates from the trigger pin. At this time, because the contact spring is in a stretched state, the elastic contraction force of the spring causes the conductive contact plates on both sides to slide towards the vertical mounting groove, separating the conductive contact plates from the knife contact plate and reducing friction. As the conductive contact plates slide inwards, they drive the trigger pin to reset upwards. As the switch knife rotates, the drive linkage gradually extends outwards to contact the knife contact plate, thereby reducing contact friction during the switch closing and opening processes.

[0010] Preferably, an elastic pad is provided between the conductive contact plate and the contact plate slide. The elastic pad is elastic and made of insulating material. The elastic force of the elastic pad ensures a tight contact between the conductive contact plate and the switch contact plate, and also protects the conductive contact plate.

[0011] Preferably, the connector is a bolt with a wire interface and a nut for locking the bolt. The bolt is threaded onto a horizontal connecting plate, and the high-voltage wire is inserted into the wire interface and the high-voltage wire is pressed onto the connector by the locking nut.

[0012] Preferably, the connector is a quick-connect reversing connection mechanism, which includes a reversing shaft rotatably mounted on a horizontal connecting plate. A quick-connect connector mechanism is fixedly provided at the upper end of the reversing shaft, and a reversing lock is provided at the lower part of the reversing shaft for locking the connector mechanism after rotation. The connector mechanism is rotatably mounted on the horizontal connecting plate via the reversing shaft, which can adjust the wiring direction of the high-voltage conductor in the horizontal direction, preventing the conductor from bending when connected to the disconnecting switch and affecting the connection stability of the conductor.

[0013] Preferably, the connector mechanism includes a snap-fit ​​base, a conductive socket is fixedly disposed inside the snap-fit ​​base, the conductive socket is provided with a socket for inserting a high-voltage wire connector, a conductive plug is provided at the bottom of the socket for conductive connection with a high-voltage conductor, and wedge-shaped blocks for clamping the high-voltage wire connector are slidably connected to both sides of the conductive socket, the high-voltage wire connector is provided with a wedge-shaped inclined surface that cooperates with the wedge-shaped blocks, and the side of the wedge-shaped blocks away from the high-voltage wire connector is connected to the inner wall of the snap-fit ​​base through a block spring; When it is necessary to connect the wires, align the high-voltage wire connector with the socket, and then push the high-voltage wire connector into the socket. The wedge-shaped inclined surface of the connector drives the two sets of wedge-shaped blocks to slide outward, so that the connector passes through the two sets of wedge-shaped blocks and is inserted into the conductive plug. Then, the two sets of wedge-shaped blocks rebound and reset under the elastic action of the stop spring, which limits the connection of the high-voltage wire connector, prevents the connection from falling off, and ensures the connection is stable.

[0014] Preferably, an unlocking shaft is rotatably provided inside the locking seat, and one end of the unlocking shaft extends out of the locking seat and is fixedly connected to an unlocking knob; an unlocking gear is fixedly provided on the unlocking shaft, and two sets of unlocking racks are meshed on the unlocking gear. The two sets of unlocking racks are arranged in a circular array around the unlocking gear, and the two sets of unlocking racks are respectively fixedly connected to a wedge-shaped stop on the same side through a connecting rod. When it is necessary to separate the high-voltage wire connector from the conductive plug, the wedge-shaped stop blocks limit the high-voltage wire connector, preventing it from being pulled out of the socket normally. At this time, turning the unlocking knob drives the unlocking gear to rotate. As the unlocking gear rotates, it drives the two sets of unlocking racks to slide outward synchronously. Under the transmission of the connecting rod, it drives the two sets of wedge-shaped stops to slide outward synchronously, thereby canceling the limitation on the high-voltage wire connector. At this time, the high-voltage wire connector can be pulled out of the socket.

[0015] Preferably, the reversing lock includes a prism sleeve fixedly disposed at the lower end of the horizontal connecting plate. The outer circumference of the prism sleeve is a polygonal prism, and the number of prisms is adjusted according to the reversing angle of the joint mechanism. The inner circumference of the prism sleeve is rotatably connected to the reversing shaft through a bearing. An outer prism hole sleeve is slidably fitted on the outer circumference of the prism sleeve along the axial direction. An inner prism hole sleeve is coaxially disposed inside the outer prism hole sleeve. The inner circumference of the inner prism hole sleeve is a polygonal prism hole. A prism shaft that mates with the inner circumference of the inner prism hole sleeve is disposed at the lower part of the reversing shaft. A tension spring is fitted on the outer circumference of the inner prism hole sleeve. The upper and lower ends of the tension spring are rotatably connected to the prism sleeve and the outer prism hole sleeve, respectively. The tension spring is used to drive the outer prism hole sleeve to automatically retract and reset. When the connector mechanism needs to be reversed, pull down the outer prism sleeve to separate it from the prism sleeve. At this time, the inner prism sleeve is still in contact with the prism shaft. Then rotate the outer prism sleeve, and under the transmission action of the inner prism sleeve, drive the reversing shaft to rotate and adjust the wiring direction of the connector mechanism. After the wiring direction is adjusted, release the outer prism sleeve. Under the elastic action of the tension spring, the outer prism sleeve will retract upward along the outer circumference of the prism sleeve to reset. At this time, the prism sleeve forms an axial limit on the outer prism sleeve, thus locking the connector mechanism after reversal.

[0016] The beneficial effects of this invention are as follows: by using a knife contact plate made of wear-resistant conductive material to reduce contact wear during the switching operation, and combined with the knife lock design to ensure reliable locking of the closed state, the problem of increased contact resistance and unstable connection caused by contact wear is effectively solved. It has the advantages of reducing contact wear, improving connection stability and extending service life. Attached Figure Description

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Please see Figures 1-11 As shown, the present invention is an outdoor high-voltage disconnect switch, comprising: The isolating base 1 is used to fix the isolating switch. Two sets of insulating supports 2 are fixedly installed on the isolating base 1. The connecting contact 3 is fixedly installed on the insulating support 2. One end of the connecting contact 3 is provided with a terminal 4 connected to the high voltage wire, and the other end is fixedly provided with a switch bracket 5 for installing the switch knife 6. The switch knife 6 has one end rotatably mounted on the knife bracket 5 of one set of connecting contacts 3, and the other end is in contact with or separated from another set of connecting contacts 3 to realize the switch on and off control. The switch knife 6 includes two sets of knife plates 61 arranged side by side. The two sides of the two sets of knife plates 61 are connected by knife shafts 62, and one set of knife shafts 62 is rotatably mounted on the knife bracket 5. A knife shaft spring 63 for adjusting the distance between the two sets of knife plates 61 is sleeved on the knife shaft 62. Two knife contact plates 64 are provided on the opposite surfaces of the two sets of knife plates 61. The knife contact plates 64 contact the connecting contact head 3 to realize circuit conduction. The knife contact plates 64 are made of wear-resistant conductive material. A knife lock for locking the latch is provided between the two sets of knife plates 61.

[0022] In practical applications, the isolating base 1 can be understood as a basic structure used to support and fix the entire disconnecting switch. It can be installed by bolts, welding, or other mechanical fixing methods to ensure the stability of the overall equipment. The insulating support 2, as a supporting component, can be made of insulating materials such as ceramics or epoxy resin. Its main function is to isolate the connecting contact 3 from the ground or other conductive parts, thereby preventing current leakage.

[0023] Furthermore, the design of the connecting contact 3 can be implemented in various ways. For example, it can be fixed to the insulating post 2 by threaded connection, snap-fit ​​connection, or welding to meet different installation requirements. The terminal 4 can be designed in various forms, such as bolt-type terminal, plug-in terminal, or crimp-type terminal, to adapt to different types of high-voltage wire connection requirements.

[0024] Specifically, in the structural design of the switch blade 6, the side-by-side arrangement of the blade plates 61 can be achieved through other means, such as a single blade plate or a combination of multiple blade plates, to meet different current carrying requirements. The rotating installation of the blade shaft 62 can be achieved through bearings, sliding bushings, or other rotating support structures to reduce frictional resistance and improve rotational flexibility. The blade shaft spring 63 serves to dynamically adjust the spacing between the blade plates 61, and can be achieved through compression springs, tension springs, or torsion springs to ensure appropriate contact pressure during closure.

[0025] Furthermore, the wear-resistant conductive material of the knife switch contact plate 64 can be selected from copper alloy, silver alloy, or other metal materials with high conductivity and wear resistance to reduce material wear caused by long-term use. The knife switch lock can be designed with a mechanical latch, electromagnetic lock, or other locking mechanism to ensure that the switch knife 6 remains stable in the closed state.

[0026] The innovation of this application lies in effectively reducing the friction and wear of the contacts during switching operations by optimizing the structural design of the switch blade 6. Specifically, the layout of the double blade plate 61, combined with the dynamic adjustment function of the blade shaft spring 63, can provide appropriate contact pressure when closed, avoiding poor contact due to insufficient pressure or increased friction damage due to excessive pressure. At the same time, the blade contact plate 64 is made of wear-resistant conductive material, further reducing the risk of material loss. These designs work together to solve the wear problems caused by contact friction and poor contact in the prior art, improving the safety and service life of the equipment.

[0027] The working principle of this embodiment is as follows: The isolation base 1 is used to fix and install the disconnect switch, providing stability support for the overall structure. Two sets of insulating supports 2 are fixedly installed on the isolation base 1, serving to support the connecting contact 3. The connecting contact 3 is fixedly installed on the insulating supports 2, one end of which is connected to the high-voltage wire through a terminal 4, and the other end is provided with a knife bracket 5 for installing the switch knife 6. One end of the switch knife 6 is rotatably installed on the knife bracket 5 of one set of connecting contacts 3, and the other end controls the circuit opening and closing by contacting or separating from the other set of connecting contacts 3.

[0028] Furthermore, the switch 6 consists of two sets of knife plates 61 arranged side by side. The two sets of knife plates 61 are connected by knife shafts 62 on both sides. One set of knife shafts 62 is rotatably mounted on the knife support 5, forming a pivot point. A knife shaft spring 63 is sleeved on the knife shaft 62 to dynamically adjust the distance between the two sets of knife plates 61, ensuring that appropriate contact pressure is maintained in the closed state, avoiding poor contact due to insufficient pressure or aggravated friction damage due to excessive pressure. Two knife contact plates 64 are provided on the opposite surfaces of the two sets of knife plates 61. These contact plates are made of wear-resistant conductive material, which can realize circuit conduction when in contact with the connecting contact head 3, while significantly reducing material loss during friction and extending service life.

[0029] Specifically, when the switch 6 is closed, the two sets of switch plates 61 maintain an appropriate distance under the action of the switch shaft spring 63, ensuring that the switch contact plate 64 is in close contact with the connecting contact 3, thereby achieving stable circuit conduction. At this time, the switch lock set between the two sets of switch plates 61 can lock the latch, preventing the switch 6 from accidentally loosening in the closed state and maintaining a stable contact state. When the switch 6 is opened, the switch contact plate 64 separates from the connecting contact 3, realizing the circuit disconnection control. Thus, the design of the double switch plate 61 not only disperses the current load and reduces the risk of single-point wear, but also effectively reduces the frictional damage of the contacts during switch operation through the synergistic effect of the switch shaft spring 63 and the wear-resistant conductive material, solving the wear problem caused by friction and poor contact, and improving the safety and service life of the equipment.

[0030] For further details, please refer to Figures 1-3 As shown, the specific structure of the knife lock includes a first pin 65 and a second pin 67 fixedly installed between two sets of knife plates 61. A limiting hook 66 for locking the hook at the lower end of the connecting contact 3 is rotatably installed on the first pin 65. An unlocking frame 68 for controlling the rotation of the first pin 65 to unlock is rotatably installed on the second pin 67. A torsion spring 69 is sleeved on both the first pin 65 and the second pin 67. One end of the torsion spring 69 is connected to the knife plate 61, and the other end of the torsion spring 69 is connected to the limiting hook 66 and the unlocking frame 68. The limiting hook 66 and the unlocking frame 68 are both made of insulating material.

[0031] Specifically, pin 65 serves as the basic support for the limit hook 66. It can be made of high-strength metal to ensure a stable installation base in outdoor vibration environments. In practical applications, pin 65 is fixed between the two sets of knife plates 61 via interference fit or threaded connection, forming a stable installation frame. Pin 67 is the rotating support for the unlocking bracket 68, which also needs to have high mechanical strength and wear resistance to ensure reliability during long-term use. The limit hook 66 is a locking component with a hook-like structure. It is rotatably installed via pin 65 and can automatically engage with the bottom groove of the connecting contact 3 when the switch is closed, thereby achieving a reliable locking function.

[0032] The unlocking bracket 68 can be understood as an operating mechanism that controls the limiting hook 66 through rotation. Specifically, there is a mechanical linkage between the unlocking bracket 68 and the limiting hook 66. When an external force is applied to the unlocking bracket 68, its rotation is transmitted to the limiting hook 66 through the pin 65, causing it to disengage from the connecting contact head 3. The pin torsion spring 69 is an elastic element whose main function is to provide a restoring force, allowing all components to automatically return to their positions after the unlocking operation, while maintaining the preload of the limiting hook 66 in the closed state.

[0033] In detail, this solution constructs a stable mounting frame using pins 65 and 67, ensuring the entire locking mechanism is not easily displaced in outdoor vibration environments. The limit hook 66 is rotatably mounted on pin 65 and engages with the lower end of the connecting contact 3. Its hook-like structure automatically embeds into the bottom groove of the connecting contact 3 when the switch is closed. Combined with the elastic preload of the pin torsion spring 69, the limit hook 66 remains firmly against the connecting contact 3, preventing accidental separation of the switch plate 61 due to wind vibration or mechanical impact, thus maintaining the stability of the circuit conduction. The unlocking bracket 68 is rotatably mounted on pin 67 and linked to the limit hook 66. When the operator applies external force to the unlocking bracket 68, its rotation is transmitted to the limit hook 66 via pin 65, precisely controlling the limit hook 66 to rotate around pin 65 and disengage from the connecting contact 3, achieving rapid unlocking. The pin-shaft torsion spring 69 connects the knife plate 61, the limit hook 66, and the unlocking frame 68. One end is fixed to the knife plate 61 to provide a reference fulcrum, and the other end acts on the limit hook 66 and the unlocking frame 68 respectively. After the unlocking operation, it automatically springs back to reset, which not only ensures that the limit hook 66 is reliably locked in the closed state, but also allows the unlocking frame 68 to quickly return to its original position after the operation, thus avoiding the mechanism from jamming.

[0034] The above technical solution not only resolves the contradiction between the reliability of switch status locking and ease of operation, but also significantly reduces unnecessary friction on the contact surfaces, extending the equipment's service life. Meanwhile, the limit hook 66 and unlocking bracket 68 are made of insulating material, effectively blocking any arcing paths that may occur during operation and preventing electro-corrosion of metal components under high voltage conditions, further enhancing safety for outdoor use.

[0035] For further details, please refer to Figures 4-6 As shown, the connecting contact 3 includes a horizontal connecting plate 31 fixedly installed on the insulating support 2. The horizontal connecting plate 31 is provided with a through hole for installing the terminal 4. One end of the horizontal connecting plate 31 is fixedly provided with a trigger vertical plate 32 that contacts the switch plate 61. The trigger vertical plate 32 is provided with a retractable contact mechanism. The retractable contact mechanism can extend and abut against the switch contact plate 64 when the switch plate 61 is closed to achieve conductivity, thereby reducing the friction between the switch plate 61 and the contact plate during rotation, which would otherwise cause wear of the contact plate and reduce the connection stability of the contact plate.

[0036] In detail, the horizontal connecting plate 31 is fixedly mounted on the insulating support 2, providing a stable support foundation for the entire connecting contact 3, while the through-hole facilitates the installation of the wiring terminal 4. The trigger vertical plate 32 is fixedly mounted at one end of the horizontal connecting plate 31, serving as the mounting platform for the contact mechanism and ensuring that the contact mechanism can accurately make contact with the knife plate 61. Through its unique telescopic characteristics, the contact mechanism actively extends to abut against the knife plate 64 when the knife plate 61 is closed, establishing a reliable conductive path; and automatically retracts during the rotation of the knife plate 61, effectively avoiding continuous friction on the contact during the movement of the knife plate 61. This design cleverly solves the problem of contact wear caused by long-term friction, ensuring the durable performance of the disconnecting switch under frequent operation. Through the above technical solution, not only is the service life of the contact improved, but the reliability of the connection is also significantly enhanced.

[0037] For further details, please refer to Figures 4-6As shown, the trigger vertical plate 32 is provided with a vertical plate mounting groove 321 for mounting the contact mechanism. The contact mechanism includes two sets of contact slide seats 33 symmetrically slidably disposed in the vertical plate mounting groove 321. A conductive contact plate 35 electrically connected to the switch contact plate 64 is fixedly disposed at one end of the contact slide seat 33 near the outer side of the trigger vertical plate 32. The conductive contact plate 35 is slidably connected through the side wall of the trigger vertical plate 32. A connecting groove 322 is provided at the side end of the trigger vertical plate 32 away from the terminal 4. 22 is connected to the vertical plate mounting groove 321. A trigger pin 38 is slidably installed at the connecting slide groove 322. Two sets of driving connecting rods 37 are rotatably connected to the trigger pin 38. The ends of the two sets of driving connecting rods 37 away from the trigger pin 38 are rotatably connected to the contact plate slide 33 on the same side through connecting pins 36. The switch knife 6 is provided with a trigger connecting rod 7 for driving the trigger pin 38 to slide downward. A contact plate spring 39 is fixedly installed between the two sets of contact plate slides 33. When the conductive contact plate 35 extends outward, the contact plate... Spring 39 is in a stretched state. When the switch 6 is rotated downwards to close, the triggering link 7 contacts the trigger pin 38 during the rotation, which then drives the trigger pin 38 to move downwards. At the same time, the trigger pin 38 moves downwards and drives the two sets of driving links 37 to rotate downwards, thereby driving the conductive contact plates 35 on both sides to slide outwards synchronously to abut against the switch contact plate 64 on the switch 6, completing the conductive contact. When the switch 6 is rotated upwards to disconnect the conductivity, the triggering link 7 separates from the trigger pin 38. At this time, since the contact spring 39 is in a stretched state, the elastic contraction force of the spring will drive the conductive contact plates 35 on both sides to slide towards the interior of the vertical plate mounting groove 321, so that the conductive contact plates 35 separate from the switch contact plate 64 to reduce friction. While the conductive contact plates 35 slide inwards, they drive the trigger pin 38 to reset upwards. As the switch 6 rotates, the driving link 37 gradually extends outwards to contact the switch contact plate 64, thereby reducing the contact friction during the switch closing and opening process.

[0038] Specifically, the vertical plate mounting groove 321 refers to the groove structure set on the trigger vertical plate 32, which can be implemented using a straight or arc-shaped groove, with the purpose of providing a stable sliding track for the contact mechanism. The contact plate slide 33 refers to the component that can slide along the vertical plate mounting groove 321, which can achieve the sliding function through a slider, ball bearing slide rail, etc., with the purpose of ensuring the smooth movement of the conductive contact plate 35. The conductive contact plate 35 refers to the metal component that forms a conductive connection with the switch contact plate 64, which can be made of highly conductive materials such as copper or silver, and is fixed to the contact plate slide 33 by welding or mechanical pressing, with the purpose of achieving a reliable electrical connection. The trigger pin 38 refers to the columnar component that can slide up and down within the connecting groove 322, which can be implemented in the form of a cylindrical pin, square pin, etc., with the purpose of converting the rotational motion of the switch switch 6 into linear displacement. The drive linkage 37 is the transmission component connecting the trigger pin 38 and the contact slide 33. It can be a rigid or flexible linkage, and its purpose is to convert the vertical movement of the trigger pin 38 into the horizontal sliding of the contact slide 33. The contact spring 39 is the elastic component connecting the two sets of contact slides 33. It can be implemented in the form of a coil spring, leaf spring, etc., and its purpose is to store elastic potential energy and achieve automatic reset.

[0039] Specifically, the above solution fundamentally solves the wear problem caused by contact friction during switch operation by constructing a precise mechanical linkage system. The vertical plate mounting groove 321 on the trigger vertical plate 32 provides a stable sliding track for the contact mechanism, allowing the contact plate slide 33 to move smoothly along the groove and avoiding contact offset caused by shaking. The symmetrical design of the contact plate slide 33 and the conductive contact plate 35 ensures uniform force on both sides of the contact points. The structure of the conductive contact plate 35 sliding through the side wall of the trigger vertical plate 32 realizes direct conductive connection with the switch contact plate 64, while reserving physical space for telescopic movement. The cooperation between the connecting groove 322 and the trigger pin 38 converts the rotational motion of the switch switch 6 into the linear displacement of the trigger pin 38. The trigger link 7 is fixed on the switch switch 6. When the switch switch rotates downward to close, the trigger link 7 moves with the switch switch and contacts the trigger pin 38. This design triggers subsequent actions according to the real-time position of the switch switch rotation, avoiding friction caused by premature or late contact. When the trigger pin 38 moves downward, the vertical motion is converted into the horizontal sliding of the contact plate slide 33 via the drive link 37. This linkage transmission mechanism precisely controls the extension range of the conductive contact plate 35 according to the displacement of the trigger pin 38, ensuring that the conductive contact plate 35 only comes into contact with the gate contact plate 64 before the gate is fully closed, thus eliminating sliding friction during the closing process. The contact plate spring 39 is stretched and stores elastic potential energy when the conductive contact plate 35 extends. When the gate rotates upward to disconnect, the trigger link 7 separates from the trigger pin 38, and the spring's contraction force automatically pulls the contact plate slide 33 inward according to the pre-stored elastic potential energy, causing the conductive contact plate 35 to retract quickly. This mechanism achieves instant separation in the disconnected state based on the physical characteristics of the spring, avoiding continuous scraping between the contact piece and the contact plate during gate rotation. At the same time, when the conductive contact plate 35 slides inward, the drive link 37 pushes the trigger pin 38 upward to reset, forming a complete closed-loop action, ensuring that the mechanism returns to its initial state after each operation. The entire system directly drives the trigger linkage 7 through the rotation of the switch knife 6, achieving strict synchronization between the extension and retraction of the contact piece and the switching action. This ensures tight contact during conduction and eliminates mechanical wear during non-conductive states, thereby significantly improving the durability of the contacts and the stability of the electrical connection.

[0040] For further details, please refer to Figures 4-6 As shown, an elastic pad 34 is provided between the conductive contact plate 35 and the contact plate slide 33. The elastic pad 34 is elastic and made of insulating material. The elastic force of the elastic pad 34 ensures that the conductive contact plate 35 and the knife contact plate 64 are in close contact, and also protects the conductive contact plate 35.

[0041] Specifically, the elastic pad 34 refers to an intermediate layer structure with elastic and insulating properties. It can be made of materials such as silicone, polyurethane elastomer or rubber. Its purpose is to absorb dynamic impact force through the elastic deformation of the material, while using its insulating properties to isolate external electrical interference.

[0042] In detail, the introduction of the elastic pad 34 effectively solves the mechanical impact problem caused by the rigid connection of the conductive contact 35 during contact. When the switch is activated, the conductive contact 35 moves towards the knife contact 64 under the guidance of the contact slide 33. At this time, the elastic pad 34 absorbs the impact force at the moment of contact through its own elastic deformation, avoiding instantaneous high-pressure wear caused by rigid collision. At the same time, the self-adaptive deformation capability of the elastic pad 34 ensures uniform contact pressure between the conductive contact 35 and the knife contact 64, thereby maintaining a stable conductive path. In addition, the insulating properties of the elastic pad 34 not only prevent the risk of short circuits that may be caused by material conductivity, but also form a barrier against electrical interference in the external environment, ensuring operational safety. The elastic force of the elastic pad 34 can dynamically adjust the pressure according to the slight changes in the contact surface, continuously compensating for manufacturing tolerances or thermal expansion differences during switch operation, avoiding contact resistance fluctuations and local overheating caused by insufficient pressure. This design significantly improves the reliability of the disconnecting switch under frequent operation and extends the service life of the contact assembly.

[0043] Through the above technical solution, the contact between the conductive contact plate 35 and the knife contact plate 64 is more stable, reducing the damage to the contact surface caused by mechanical impact and uneven contact pressure, thereby reducing the risk of increased contact resistance and effectively avoiding welding or connection failure.

[0044] For further details, please refer to Figures 1-2 As shown, connector 4 consists of a bolt with a wire interface and a lock nut. The bolt is threaded onto the horizontal connecting plate 31. The high-voltage wire is inserted into the wire interface and the lock nut presses the high-voltage wire onto connector 3.

[0045] In detail, this technical solution utilizes the threaded connection between the bolt and the horizontal connecting plate 31, leveraging the self-locking property of the thread to ensure the secure fixation of the terminal 4 on the horizontal connecting plate 31. Simultaneously, after the high-voltage wire is inserted into the wire interface of the bolt, the axial pressure applied by the lock nut evenly presses the wire against the surface of the connecting contact 3. This clamping mechanism not only suppresses wire displacement caused by external vibration or pulling but also reduces the risk of oxidation and wear on the contact surface, thereby extending the service life of the equipment. Furthermore, since the bolt itself has a conductive interface function, the wire installation process is simplified, improving operational convenience. Overall, this solution, through the cooperation of the bolt and lock nut, constructs an immediate, stable, and long-term reliable wire connection mechanism, significantly enhancing the operational reliability and safety of the disconnecting switch in complex outdoor environments.

[0046] For further details, please refer to Figures 7-11As shown, terminal 4 is a quick-connect reversing connection mechanism. The quick-connect reversing connection mechanism includes a reversing shaft 42 rotatably mounted on a horizontal connecting plate 31. A quick-connect connector mechanism 41 is fixedly installed at the upper end of the reversing shaft 42. A reversing lock 43 is provided at the lower part of the reversing shaft 42 for locking the connector mechanism 41 after rotation. The connector mechanism 41 is rotatably mounted on the horizontal connecting plate 31 via the reversing shaft 42, which can adjust the wiring direction of the high-voltage wire in the horizontal direction to avoid bending of the wire when connected to the disconnecting switch, thus affecting the connection stability of the wire.

[0047] In detail, this solution utilizes the rotating installation of the reversing shaft 42 and the horizontal connecting plate 31 to allow the connector mechanism 41 to rotate freely in the horizontal plane, thereby dynamically adjusting the wiring direction according to the actual conductor routing. This design effectively avoids the stress concentration problem caused by the forced bending of conductors in traditional fixed connectors. The quick-connect feature of the connector mechanism 41 is achieved through a plug-in connection, which not only simplifies the operation steps but also ensures the stability and safety of the electrical connection. The design of the reversing lock 43 ensures that the connector mechanism 41 remains stable after being adjusted to the appropriate direction through mechanical constraints, preventing directional deviation caused by vibration or external forces. In the overall solution, the layout and functional design of each component work together to solve the problem of conductor bending while improving the convenience and reliability of wiring operations.

[0048] The above technical solution enables flexible adjustment of the wiring direction of high-voltage conductors, eliminates mechanical stress and electrical contact hazards caused by conductor bending, and significantly improves the adaptability and connection reliability of disconnecting switches in complex installation environments.

[0049] For further details, please refer to Figures 7-11 As shown, the connector mechanism 41 includes a snap-fit ​​base 411, within which a conductive socket 412 is fixedly disposed. The conductive socket 412 has a socket for inserting a high-voltage wire connector. A conductive plug 413, conductively connected to the high-voltage conductor, is located at the bottom of the socket. Wedge-shaped stops 414 for clamping the high-voltage wire connector are slidably connected to both sides of the conductive socket 412. The high-voltage wire connector has a wedge-shaped inclined surface that mates with the wedge-shaped stops 414. The side of the wedge-shaped stops 414 furthest from the high-voltage wire connector passes through… The stop spring 415 is connected to the inner wall of the snap-fit ​​seat 411. When it is necessary to connect the wire, the high-voltage wire connector is aligned with the socket, and then the high-voltage wire connector is pushed into the socket. The wedge-shaped inclined surface of the connector drives the two sets of wedge-shaped stops 414 to slide outward, so that the connector passes through the two sets of wedge-shaped stops 414 and is inserted into the conductive plug 413. Then, the two sets of wedge-shaped stops 414 rebound and reset under the elastic action of the stop spring 415, which limits the connection of the high-voltage wire connector, prevents the connection from falling off, and ensures the connection is stable.

[0050] In detail, this solution achieves rapid and reliable connection of high-voltage wire connectors through the organic cooperation of various components. The snap-fit ​​base 411 serves as the basic support structure, providing a stable installation platform for the entire connector mechanism while ensuring necessary electrical insulation performance. The conductive socket 412 is located inside the snap-fit ​​base 411, and its socket provides a precise guide channel for the high-voltage wire connector, while the conductive plug 413 at the bottom of the socket directly forms a reliable electrical connection point with the high-voltage wire. The wedge-shaped stops 414 on both sides of the conductive socket 412 are installed via a sliding through-hole method, dynamically adjusting their position according to external forces. When the high-voltage wire connector is inserted, the geometric features of the connector's wedge-shaped inclined surface naturally push the wedge-shaped stops 414 outwards during the insertion process, achieving automatic unlocking. A stop spring 415 connects the wedge-shaped stops 414 to the inner wall of the snap-fit ​​base 411, providing stable elastic restoring force. When the connector is fully inserted, the wedge-shaped stops 414 automatically spring back to their original position under the action of the spring, locking into the wedge-shaped inclined surface of the connector, forming a bidirectional limiting position. This design not only ensures that the wire connector is firmly locked after insertion, but also, in conjunction with the aforementioned quick-connect reversing wiring mechanism, effectively solves the problem of loose connection caused by vibration or external force, significantly improving the safety and reliability of the disconnecting switch.

[0051] The above technical solution enables quick insertion and reliable locking of high-voltage wire connectors, effectively avoiding the cumbersome operation of traditional screw-locking structures, and solving the safety hazards caused by unstable wiring.

[0052] For further details, please refer to Figures 7-11 As shown, an unlocking shaft 416 is rotatably mounted inside the locking seat 411. One end of the unlocking shaft 416 extends out of the locking seat 411 and is fixedly connected to an unlocking knob 419. An unlocking gear 417 is fixedly mounted on the unlocking shaft 416. Two sets of unlocking racks 418 are meshed on the unlocking gear 417. The two sets of unlocking racks 418 are arranged in a circular array around the unlocking gear 417. The two sets of unlocking racks 418 are respectively fixedly connected to a wedge-shaped stop 414 on the same side via connecting rods. When it is necessary to connect the high-voltage wire connector... When separating from the conductive plug 413, the high-voltage wire connector cannot be pulled out of the socket normally because the wedge-shaped stop 414 limits the high-voltage wire connector. At this time, turn the unlocking knob 419 to drive the unlocking gear 417 to rotate. While the unlocking gear 417 rotates, it drives the two sets of unlocking racks 418 to slide outward synchronously. Under the transmission of the connecting rod, it drives the two sets of wedge-shaped stops 414 to slide outward synchronously, thereby canceling the limitation on the high-voltage wire connector. At this time, the high-voltage wire connector can be pulled out of the socket.

[0053] In detail, the above solution solves the problem of high-voltage wire connectors being difficult to separate after automatic locking through the design of the unlocking mechanism. The rotation setting of the unlocking shaft 416 allows for precise control of the internal unlocking action through external operation, avoiding the complexity caused by directly operating the internal mechanism. The unlocking knob 419 provides an intuitive manual operation interface, allowing users to easily apply rotational force and simplifying the operation process. The unlocking gear 417 directly transmits the rotational motion of the unlocking shaft 416 to the gear system, ensuring the synchronicity and reliability of motion conversion. Two sets of unlocking racks 418 are arranged in a circular array around the unlocking gear 417. This symmetrical layout ensures that the unlocking racks 418 on both sides move synchronously when the gear rotates, eliminating the jamming or offset problems that may be caused by uneven force on one side. The unlocking racks 418 are fixedly connected to the wedge-shaped stop 414 on the same side through a connecting rod. According to the linear sliding of the unlocking racks 418, the connecting rod accurately transmits the motion to the wedge-shaped stop 414, allowing the wedge-shaped stop 414 to slide outward in a coordinated manner, ensuring the uniformity of limit release. This mechanism utilizes the mechanical advantages of gear and rack meshing to achieve precise control of the wedge-shaped stop 414, solving the problem of difficulty in separation after automatic locking, while avoiding equipment damage caused by forced removal. Through this technical solution, not only is equipment maintenance efficiency and safety improved, but the overall structural stability and reliability are also enhanced.

[0054] For further details, please refer to Figures 7-11 As shown, the reversing lock 43 includes a prism sleeve 431 fixedly installed at the lower end of the horizontal connecting plate 31. The outer periphery of the prism sleeve 431 is a polygonal prism. The number of prisms is adjusted according to the reversing angle of the joint mechanism 41. The inner periphery of the prism sleeve 431 is rotatably connected to the reversing shaft 42 through a bearing 432. An outer prism hole sleeve 433 is slidably fitted on the outer periphery of the prism sleeve 431 along the axial direction. An inner prism hole sleeve 434 is coaxially arranged inside the outer prism hole sleeve 433. The inner periphery of the inner prism hole sleeve 434 is a polygonal prism hole. A prism shaft 421 that mates with the inner periphery of the inner prism hole sleeve 434 is provided at the lower part of the reversing shaft 42. A tension spring 435 is fitted on the outer periphery of the inner prism hole sleeve 434. The upper and lower ends of the tension spring 435 are rotatably connected to the prism sleeve 431 and the outer prism hole sleeve 433, respectively. The tension spring 435 is used to drive the outer prism hole sleeve 433 to automatically retract and reset. When it is necessary to reverse the wiring of the connector mechanism 41, pull down the outer prism sleeve 433 to separate it from the prism sleeve 431. At this time, the inner prism sleeve 434 is still in contact with the prism shaft 421. Then rotate the outer prism sleeve 433, and under the transmission action of the inner prism sleeve 434, drive the reversing shaft 42 to rotate and adjust the wiring direction of the connector mechanism 41. After the wiring direction is adjusted, release the outer prism sleeve 433. Under the elastic action of the tension spring 435, drive the outer prism sleeve 433 to retract upward along the outer circumference of the prism sleeve 431 to reset. At this time, the prism sleeve 431 forms an axial limit on the outer prism sleeve 433, thus locking the connector mechanism 41 after reversal.

[0055] Specifically, the prism sleeve 431 refers to a support component with a polygonal outer perimeter structure, which can be made of metal or high-strength engineering plastics, and is intended to provide a stable mounting base and generate multiple precise locking angle positions. The outer prism hole sleeve 433 can be understood as a sleeve structure capable of sliding axially, which can have its wear resistance enhanced through surface treatment technology to ensure reliability during long-term use. Furthermore, the inner prism hole sleeve 434 is a transmission component with a matching prism hole inside, intended to achieve rigid engagement with the prism shaft 421, thereby eliminating the possibility of relative rotation. The tension spring 435 is an elastic element, which can be made of spring steel of different materials and elastic coefficients, and is intended to generate an automatic reset driving force and ensure the stability of the locked state.

[0056] Specifically, this solution uses a prism sleeve 431 fixed to the lower end of the horizontal connecting plate 31 as a basic support, preventing the reversing lock 43 from shifting entirely during vibration. The polygonal prism design on the outer periphery of the prism sleeve 431 generates multiple precise locking angle positions, ensuring that the wiring direction can only remain at a preset angle, preventing connection offset caused by arbitrary rotation. The inner periphery of the prism sleeve 431 is rotatably connected to the reversing shaft 42 via a bearing 432, generating a smooth rotation path, ensuring that the connector mechanism 41 is free from jamming during adjustment. The outer prism sleeve 433 generates a switching channel for unlocking and locking based on its axial sliding characteristics, simplifying the operation steps. The inner prism sleeve 434 cooperates with the prism shaft 421 to generate a rigid engagement state, completely eliminating the possibility of relative rotation when locked. The elastic deformation of the tension spring 435 generates an automatic reset driving force, ensuring that the outer prism sleeve 433 can immediately spring back to the locked position after being released. The entire process only requires three actions—pulling, rotating, and releasing—to complete reliable locking, significantly improving the convenience of on-site operation and connection stability.

[0057] The above technical solution effectively solves the problems of unreliable locking and complex operation after adjusting the wiring direction, ensuring that the high-voltage wire connector can stably adapt to different connection directions in outdoor environments and avoid bending. Meanwhile, the design based on the prism structure and spring reset mechanism not only improves the ease of operation of the reversing lock 43, but also enhances its reliability in long-term use, thereby reducing the risk of connection loosening due to vibration or external forces.

All equivalent variations and modifications made within the scope of the claims of this invention should still fall within the patent coverage of this invention.
