Description

Technical Field

[0001] This invention relates to the field of gas-insulated switchgear technology, and more particularly to environmentally friendly gas-insulated metal-enclosed switchgear. Background Technology

[0002] In modern power systems, environmentally friendly gas-insulated metal-enclosed switchgear (hereinafter referred to as "environmentally friendly GIS") is a highly efficient, reliable, and environmentally friendly electrical device widely used between the power supply side and the load side of the power system. This device can not only realize the normal switching of circuits, but also protect the power system and load equipment by safely disconnecting the current when abnormal currents such as grounding or short circuits occur. This gas-insulated switchgear consists of components such as a first bushing that receives power from the high-voltage power source, a gas circuit breaker, a circuit breaker, a grounding switch, a movable part, and a control part.

[0003] Among them, the grounding switch plays a crucial role in environmental GIS. It is not only used to provide grounding protection during equipment maintenance to prevent accidental power surges from causing injury to personnel, but also to quickly connect the faulty circuit to the earth in the event of a grounding fault, so as to achieve rapid discharge of fault current. The grounding switch of environmental GIS uses environmentally friendly insulating gas as the insulating medium, which improves the safety and reliability of the equipment. At the same time, the design of the grounding switch also needs to consider the speed and high stability of the operation, so as to complete the grounding operation in a short time and ensure the safety of equipment and personnel.

[0004] The grounding switches used in existing environmentally friendly gas-insulated metal-enclosed switchgear are difficult to operate quickly during actual use. The inability of the grounding switches to complete opening and closing operations in a very short time can easily lead to arcing, exacerbating contact wear and increasing equipment failure rates. Furthermore, after closing, the equipment struggles to provide stable contact pressure, which can increase contact resistance, causing overheating or even burnout of the contacts when carrying large currents. Consequently, the safety of actual use cannot be effectively guaranteed. Therefore, those skilled in the art have provided environmentally friendly gas-insulated metal-enclosed switchgear to address the problems mentioned in the background section. Summary of the Invention

[0005] The purpose of this invention is to address the problems that existing environmentally friendly gas-insulated metal-enclosed switchgear uses grounding switches that are difficult to quickly open and close during actual use, leading to increased contact wear due to arcing, increased equipment failure rate, unstable contact pressure after closing, increased contact resistance, contact overheating, or even burnout, thereby affecting the safety and reliability of the equipment. Therefore, this invention proposes an environmentally friendly gas-insulated metal-enclosed switchgear.

[0006] To achieve the above objectives, the present invention employs the following environmentally friendly gas-insulated metal-enclosed switchgear: comprising a base, wherein a moving contact is connected to the base via a rotatably mounted operating lever, a conductive component is disposed on the base, and a contact plate corresponding to the moving contact is connected to the conductive component; further comprising:

[0007] An adjustment module includes a retainer fixedly mounted on a base, a plurality of arc-shaped slides corresponding one-to-one with the moving contacts fixedly mounted on the retainer, and an adjustment bracket slidably mounted on the arc-shaped slides;

[0008] An elastic booster module is slidably mounted on an adjusting bracket. An L-shaped baffle is fixedly mounted on one side of the moving contact. During the process of the moving contact rotating with the control lever to close the circuit, the L-shaped baffle provides an upward thrust to the elastic booster module. When the moving contact closes with the contact plate, the elastic booster module provides a squeezing force to the L-shaped baffle.

[0009] An energy storage module includes an energy storage mechanism and a toggle mechanism rotatably mounted on an adjustment bracket. The toggle mechanism provides a rotational tendency for the energy storage mechanism when the elastic booster module moves upward. When the energy storage module rotates from a horizontal to a vertical state, it is used to pull the elastic booster module to store energy.

[0010] As a further description of the above-mentioned environmentally friendly gas-insulated metal-enclosed switchgear: the arc-shaped slide includes a connecting column fixedly installed on a retainer, and two sets of frame plates are fixedly installed on the outer ring of the connecting column. Two sets of first arc rods arranged in parallel, one above the other, are fixedly installed on the frame plates.

[0011] As a further description of the above-mentioned environmentally friendly gas-insulated metal-enclosed switchgear: the adjusting bracket includes a first sleeve slidably mounted on two sets of first arc rods, and vertical rods with bottom-end connecting support frames are fixedly mounted on the upper and lower sets of first sleeves. The support frame is fixedly mounted with a frame rod for the elastic booster module to slide up and down.

[0012] As a further description of the above-mentioned environmentally friendly gas-insulated metal-enclosed switchgear: the elastic booster module includes a folding plate that is slidably installed between two sets of frame rods. A round rod that slides through the frame rod is fixedly installed on the folding plate. A vertical rod that slides through the round rod is fixedly installed inside the sliding groove of the frame rod. A T-shaped rod that connects to the energy storage mechanism is slidably installed inside the folding plate. A booster block that abuts against an L-shaped baffle is fixedly installed at one end of the T-shaped rod. A booster spring that is sleeved on the outer ring of the T-shaped rod is installed between the booster block and the folding plate.

[0013] As a further description of the above-mentioned environmentally friendly gas-insulated metal-enclosed switchgear: the energy storage mechanism includes a rotating rod rotatably mounted on a support frame, two sets of booster frames and a set of rotating plates that abut against the actuating mechanism are fixedly mounted on the rotating rod, the booster frames are internally slidably mounted with rollers that are rotatably connected to the ends of the T-shaped rods, and the support frame is provided with elastic elements for controlling the booster frames to return to a horizontal state.

[0014] As a further description of the above-mentioned environmentally friendly gas-insulated metal-enclosed switchgear: the elastic element includes two sets of support plates fixedly installed on the support frame, a second arc rod fixedly installed on the support plate, a second sleeve slidably installed on the second arc rod, a support rod fixedly installed between the second sleeve and the booster frame, and a return spring sleeved on the outer ring of the second arc rod is installed between the end of the second sleeve and one of the support plates.

[0015] As a further description of the above-mentioned environmentally friendly gas-insulated metal-enclosed switchgear: the actuating mechanism includes two sets of levers rotatably mounted on a support frame. Each set of levers has a connecting groove inside for the round rod to slide. A limiting pressure rod that abuts against the rotating plate is fixedly installed between the two sets of levers.

[0016] As a further description of the above-mentioned environmentally friendly gas-insulated metal-enclosed switchgear: the retainer is provided with a push-pull mechanism for controlling the sliding of the elastic booster module on the adjusting bracket, and the interior of the retainer is provided with a slide rail in the vertical direction for the push-pull mechanism to move.

[0017] As a further description of the above-mentioned environmentally friendly gas-insulated metal-enclosed switchgear: the push-pull mechanism includes a crossbar fixedly installed on a retainer, a rack slidably installed on the crossbar, a gear meshing with the rack rotatably installed on the outer ring of the connecting column, push rods clamping both sides of the vertical rod fixedly installed on the gear, a connecting rod hinged to the bottom of one end of the rack, and a lifting rod rotatably installed at the bottom end of the connecting rod, which can move up and down inside the slide rail.

[0018] As a further description of the above-mentioned environmentally friendly gas-insulated metal-enclosed switchgear: the control rod and the lifting rod are movably connected to a control frame that moves along a rectangular trajectory. The control frame has a first movable groove for horizontal movement of the lifting rod and a second movable groove for vertical movement of the end of the control rod. One side of the second movable groove is connected to a movable cavity for rotation of the end of the control rod.

[0019] In summary, due to the adoption of the above-mentioned technology in the environmentally friendly gas-insulated metal-enclosed switchgear, the beneficial effects of this invention are:

[0020] By incorporating cooperative elastic booster modules and energy storage modules, rapid opening and closing of the moving contact and contact plate can be achieved. The elastic booster module provides rapid boosting force during closing, ensuring the moving contact quickly contacts the contact plate. During opening, a push-pull mechanism controls the elastic booster module to rotate, providing reverse thrust to quickly separate the moving contact from the contact plate, effectively preventing arcing during opening. Rapid opening and closing operations reduce the duration of arcing, thereby reducing contact wear and arc damage to the equipment, extending its service life. Furthermore, the elastic booster module not only provides rapid boosting force during closing but also provides continuous elastic pressure after closing, ensuring stable contact between the moving contact and the contact plate. This stable contact reduces contact resistance, improving the conductivity of the grounding switch and ensuring the reliability and safety of the equipment in the closed state.

[0037] The technically advanced and environmentally friendly gas-insulated metal-enclosed switchgear of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. 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.

[0038] like Figures 1-10As shown, the environmentally friendly gas-insulated metal-enclosed switchgear provided by the present invention includes a base 10. A moving contact 13 is connected to the base 10 via an operating lever 14 rotatably mounted thereon. A conductive component 12 is provided on the base 10. The conductive component 12 is connected to a contact plate 11 corresponding to the moving contact 13. The contact plate 11 and the conductive component 12 are detachably connected by bolts. An mounting plate that is bolted to the moving contact 13 can be welded onto the operating lever 14. Rotating the operating lever 14 can drive the moving contact 13 to rotate. When the moving contact 13 is snapped between the moving contact and the contact plate 11, the grounding switch can be closed. When the moving contact 13 rotates out from inside the contact plate 11, the grounding switch can be opened. Other components of the equipment and the conductive component 12, including the insulating pole, grounding busbar, and terminals, are all existing technologies and will not be described in detail here.

[0039] To achieve rapid opening and closing of the moving contact 13 and the contact plate 11, the equipment also includes an adjustment module 20, an elastic booster module 30, and an energy storage module 40. The adjustment module 20 includes a retainer 201 fixedly mounted on the base 10. Multiple sets of arc-shaped slides 202, each corresponding to one of the moving contacts 13, are fixedly mounted on the retainer 201. Adjustment brackets 203 are slidably mounted on the arc-shaped slides 202. The elastic booster module 30 is slidably mounted on the adjustment bracket 203. An L-shaped baffle 15 is fixedly mounted on one side of the moving contact 13. The moving contact 13... During the process of rotating the control lever 14 to close the circuit, the L-shaped baffle 15 is used to provide an upward thrust to the elastic booster module 30. When the moving contact 13 closes with the contact plate 11, the elastic booster module 30 is used to provide a squeezing force to the L-shaped baffle 15. Correspondingly, the energy storage module 40 includes an energy storage mechanism 401 and a toggle mechanism 402 rotatably mounted on the adjusting bracket 203. The toggle mechanism 402 is used to provide a rotational motion tendency to the energy storage mechanism 401 when the elastic booster module 30 moves upward. When the energy storage module 40 rotates from a horizontal to a vertical state, it is used to pull the elastic booster module 30 to store energy.

[0040] When performing the grounding switch closing operation of the environmentally friendly gas-insulated metal-enclosed switchgear, the adjusting bracket 203 and its bottom-mounted elastic booster module 30 and energy storage module 40 move to the rotation path of the moving contact 13. During the rotation of the moving contact 13 controlled by the lever 14, the L-shaped baffle 15 on one side of the moving contact 13 pushes the elastic booster module 30 upwards within the adjusting bracket 203. As the elastic booster module 30 moves upwards, it drives the energy storage mechanism 401 to rotate via the actuating mechanism 402. The rotating energy storage mechanism 401 drives the elastic booster module 30 to store energy. When the moving contact 13 and the L-shaped baffle... When plate 15 rotates to the front end of elastic booster module 30, moving contact 13 approaches contact plate 11. Energy storage mechanism 401 resets and controls elastic booster module 30 to move downward. At the same time, the elastic pressure of elastic booster module 30 itself is released, which can provide rapid boost to L-shaped baffle 15 at its front end, thereby achieving the effect of rapid closing of moving contact 13 and contact plate 11. When moving contact 13 and contact plate 11 are fully closed, elastic booster module 30 itself still has a certain elastic pressure, which can provide squeezing force to L-shaped baffle 15 at its front end, achieving stable contact between moving contact 13 and contact plate 11, which is beneficial to improving the reliability and service life of equipment.

[0041] When performing the grounding switch opening operation of the environmentally friendly gas-insulated metal-enclosed switchgear, the adjusting bracket 203 can be controlled to slide on the arc-shaped slide 202, moving the adjusting bracket 203 and its connected elastic boosting module 30 and energy storage module 40 to the other side of the L-shaped baffle 15. During the rotation and movement of the elastic boosting module 30 along the path of the arc-shaped slide 202, the front end of the elastic boosting module 30 abuts against the L-shaped baffle 15, wherein the side of the L-shaped baffle 15 away from the moving contact 13 is an arc surface, which facilitates the elastic boosting... The movement of the front end of the push module 30 ensures that the elastic push module 30 always maintains a certain amount of stored energy. When the front end of the elastic push module 30 rotates 180° completely, it releases its elastic potential energy from the arc surface, which can provide a rapid reverse thrust for the L-shaped baffle 15, thereby achieving the effect of rapid opening of the moving contact 13 and the contact plate 11. Then, the operating lever 14 is used to control the rotation of the moving contact 13 to restrict it to a safe opening position. The closing and opening operations of the grounding switch can be carried out quickly, which can effectively avoid the generation of electric arc.

[0042] In one embodiment, such as Figures 1-8 As shown, specifically, the arc-shaped slide 202 includes a connecting column 2021 fixedly installed on the retainer 201. Two sets of frame plates 2022 are fixedly installed on the outer ring of the connecting column 2021. Two sets of parallel first arc rods 2023 are fixedly installed on the frame plates 2022. The fixed connection between the components can be achieved by direct welding or by bolts. The two sets of first arc rods 2023 are used to provide a rotational movement track for the adjusting bracket 203.

[0043] like Figures 2-9 As shown, specifically, the adjusting bracket 203 includes a first sleeve 2031 slidably mounted on two sets of first arc rods 2023. Vertical rods 2033 with bottom ends connected to support frame 2032 are fixedly mounted on the upper and lower sets of first sleeves 2031. Two sets of vertical rods 2033 can be provided that are fixedly connected to both the first sleeve 2031 and the support frame 2032. A frame rod 2034 for the elastic booster module 30 to slide up and down is fixedly mounted on the support frame 2032. When the first sleeve 2031 slides on the first arc rod 2023, the support frame 2032 and the frame rod 2034 can be moved and adjusted by the vertical rod 2033. The support frame 2032 can provide rotational support for the elastic booster module 30 and the energy storage module 40.

[0044] Based on the above embodiments, such as Figures 1-9 As shown, specifically, the elastic booster module 30 includes a folding plate 301 that is slidably installed between two sets of support rods 2034. A round rod 302 that slides through the support rod 2034 is fixedly installed on the folding plate 301. A vertical rod 303 that slides through the round rod 302 is fixedly installed inside the slide groove 16 of the support rod 2034. A T-shaped rod 304 that connects to the energy storage mechanism 401 is slidably installed inside the folding plate 301. A booster block 305 that abuts against an L-shaped baffle 15 is fixedly installed at one end of the T-shaped rod 304. A booster spring 306 that is sleeved on the outer ring of the T-shaped rod 304 is installed between the booster block 305 and the folding plate 301.

[0045] When the elastic booster module 30 is located on the rotation path of the moving contact 13, the moving contact 13 can drive the L-shaped baffle 15 to move to the bottom of the folding plate 301. During the continuous rotation of the L-shaped baffle 15, the folding plate 301 can be pushed to move upward between the support rods 2034. The movement of the folding plate 301 drives the round rod 302 to slide inside the slide groove 16 and on the surface of the upright rod 303. The upright rod 303 can provide stable limiting support for the up and down movement of the folding plate 301. The folding plate 301 can simultaneously drive the T-shaped rod 304, the booster block 305 and the booster spring 306 to move up and down together.

[0046] The T-shaped rod 304 is controlled by the energy storage mechanism 401 and slides inside the folding plate 301. The front end of the T-shaped rod 304 stores energy through the compressible booster spring 306 via the booster block 305. The horizontal plate of the folding plate 301 is close to horizontal. The booster block 305 can be completely retracted above the folding plate 301. After the moving contact 13 and the L-shaped baffle 15 are completely rotated to the front end of the folding plate 301, the energy storage mechanism 401 controls the folding plate 301 and other structures to move downwards. At the same time, the elastic potential energy of the booster spring 306 is released, which can control the booster block 305 to quickly push the L-shaped baffle 15 to move. At the same time, after the L-shaped baffle 15 moves to the closed position, the booster spring 306 still has a certain elastic potential energy, which provides elastic support for the L-shaped baffle 15 when the grounding switch is in the closed state.

[0047] Correspondingly, the energy storage mechanism 401 includes a rotating rod 4011 rotatably mounted on the support frame 2032. Two sets of booster frames 4012 and a set of rotating plates 4013 that abut against the actuating mechanism 402 are fixedly mounted on the rotating rod 4011. Rollers 4014 rotatably connected to the end of the T-shaped rod 304 are slidably mounted inside the booster frame 4012. An elastic element 4015 is provided on the support frame 2032 for controlling the booster frame 4012 to return to a horizontal state. The elastic element 4015 includes a support... Two sets of support plates 40151 are fixedly installed on the frame 2032. A second arc rod 40152 is fixedly installed on the support plate 40151. A second sleeve 40153 is slidably installed on the second arc rod 40152. A support rod 40154 is fixedly installed between the second sleeve 40153 and the booster frame 4012. A return spring 40155, which is sleeved on the outer ring of the second arc rod 40152, is installed between the end of the second sleeve 40153 and one of the support plates 40151.

[0048] To achieve linkage between the energy storage mechanism 401 and the elastic booster module 30, the actuation mechanism 402 includes two sets of levers 4021 rotatably mounted on the support frame 2032. Both sets of levers 4021 have a connecting groove 17 inside for the round rod 302 to slide. A limiting pressure rod 4022 that abuts against the rotating plate 4013 is fixedly installed between the two sets of levers 4021. The rotational connection between the components can be achieved by bearing connection or hinge connection.

[0049] During the movement of the round rod 302 driven by the folding plate 301, the round rod 302 can drive the lever 4021 and the limiting pressure rod 4022 at its end to rotate. When the limiting pressure rod 4022 rotates, it can drive the rotating plate 4013 to rotate. The rotating plate 4013 drives the two sets of pusher frames 4012 to rotate through the rotating rod 4011. When the pusher frame 4012 rotates, it can pull the T-shaped rod 304 to slide back and forth in the folding plate 301 through the roller 4014 set inside it. During the rotation of the pusher frame 4012, the pusher frame 4012 can also pull the T-shaped rod 304 to slide back and forth in the folding plate 301. The second sleeve 40153 can be slid on the second arc rod 40152 by the support rod 40154. When the second sleeve 40153 moves, it causes the return spring 40155 to extend and retract. When the booster frame 4012 rotates to the vertical state, the return spring 40155 and the booster spring 306 are squeezed to the limit state. When the thrust on the folding plate 301 is removed, the release of the elastic potential energy of the return spring 40155 and the booster spring 306 can control the reset of the booster frame 4012 and the ejection of the booster block 305.

[0050] To address the issue of synchronous adjustment of multiple sets of elastic booster modules 30, in one embodiment, such as Figures 1-9 As shown, the retainer 201 is provided with a push-pull mechanism 50 for controlling the sliding of the elastic booster module 30 on the adjusting bracket 203. The interior of the retainer 201 is provided with a slide rail 18 for the push-pull mechanism 50 to move in the vertical direction. In detail, the push-pull mechanism 50 includes a crossbar 501 fixedly installed on the retainer 201, a rack 502 slidably installed on the crossbar 501, a gear 503 that meshes with the rack 502 is rotatably installed on the outer ring of the connecting column 2021, a push rod 504 that clamps on both sides of the vertical rod 2033 is fixedly installed on the gear 503, a connecting rod 505 is hinged to the bottom of one end of the rack 502, and a lifting rod 506 that can move up and down inside the slide rail 18 is rotatably installed at the bottom end of the connecting rod 505.

[0051] When the operator moves the lifting rod 506 up and down, the rack 502 can slide on the crossbar 501 via the connecting rod 505. When the rack 502 moves, it drives the gear 503 and the push rod 504 to rotate. The push rod 504 can drive the adjusting bracket 203 to slide on the arc slide 202. During the process of adjusting the grounding switch from closing to opening, the push-pull mechanism 50 can be used to control the adjusting bracket 203 and its connecting structure to rotate 180°. The elastic booster module 30 on the adjusting bracket 203 can be adjusted to the back of the L-shaped baffle 15 to provide boosting force. In order to facilitate the adjustment bracket 203 and its connecting structure to rotate onto the rotation path of the L-shaped baffle 15, the central axis of the connecting column 2021, which is the rotation center of the adjusting bracket 203 and its connecting components, is offset from the contact plate 11 by a certain distance to avoid the contact plate 11 affecting the rotation of the adjusting bracket 203 and its connecting components.

[0052] like Figure 10As shown, the joystick 14 and the lifting rod 506 are movably connected to a control frame 19 that moves along a rectangular trajectory. The control frame 19 has a first movable groove 110 for horizontal movement of the lifting rod 506 and a second movable groove 111 for vertical movement of the end of the joystick 14. One side of the second movable groove 111 is connected to a movable cavity 112 for rotation of the end of the joystick 14.

[0053] The environmentally friendly gas-insulated metal-enclosed switchgear can be equipped with a rectangular track for the control frame 19 to move. A lever can be provided at a distance from the center of gravity of the control frame 19 for easy operation by the operator. The operator can achieve the closing and opening of the grounding switch by pulling the control frame 19 with the lever. The closing and opening operations of the equipment consist of two stages. The first stage moves up and down to control the rotation of the adjusting bracket 203 and its connecting components. The second stage moves left and right to control the rotation of the operating lever 14 and the moving contact 13. The operation of the grounding switch is simple and easy to learn, and its stability and safety are also high.

[0054] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the present invention's technical environmentally friendly gas-insulated metal-enclosed switchgear and inventive concept, should be covered within the scope of protection of the present invention.
