Description

Technical Field

[0001] The invention relates to the technical field of GIS switch cabinets, in particular to a GIS switch cabinet with a stable safety device. Background Art

[0002] Switch cabinet is an electrical equipment, which can be divided into removable (trolley type) and fixed type according to the installation of circuit breaker. It is mainly used in mining areas, residential areas, high-rise buildings, parks and other places to receive and distribute electric energy.

[0003] At least one circuit breaker is usually arranged in the switch cabinet to open or close the main circuit. The circuit breaker is usually rocked in and out of the switch cabinet by a chassis vehicle to move between at least a test position and a service position. In the service position, the moving contact and the stationary contact of the circuit breaker are electrically coupled together, and the circuit breaker can complete the closing and opening operations. In the test position, the circuit breaker can also complete the closing operation to perform the corresponding test.

[0004] The circuit breaker in the switch cabinet is installed on a removable trolley. The static contact is installed in the switch cabinet and connected to the conductor line. It is generally divided into two parts, upper and lower. The contact arm and the static contact are connected or disconnected by pushing or pulling out the circuit breaker trolley, that is, the circuit is connected or disconnected. Since the static contact is a normally energized end, in order to prevent maintenance personnel from accidentally touching the static contact when repairing the circuit and endangering personal safety, an upper and lower valve linked to the circuit breaker trolley is set in front of the static contact to cover the two sets of energized static contacts for safety protection.

[0005] The existing safety devices can refer to the Chinese utility model patent with the authorization announcement number CN215419295U, which discloses a static contact safety device and a switch cabinet. "In view of the problem that the electrical distance between the existing valve and the static contact is solved by composite insulation, but in order to ensure that the switch cabinet has IAC-level arc resistance and long-term operation reliability, the switch cabinet body is not allowed to use composite insulation, a static contact safety device and a switch cabinet are provided. Through structural design, the problem of the electrical distance between the valve and the static contact can be solved, and the arc resistance and long-term operation reliability of the switch cabinet can be ensured." When the above equipment is in use, if there is no trolley in the switch cabinet, the maintenance personnel may move the valve by toggling the valve or the transmission rod, which may cause the valve to fail to reliably isolate and seal the live static contacts; However, personnel can open the valve plate at will, and it is very easy to contact the live static contacts in the contact box, which may cause casualties and pose a great safety hazard.

[0016] The present invention has the following beneficial effects: 1. The GIS switch cabinet with a stable safety device covers the fixed plate 2, the rotating frame, the rotating wheel and the pull rod through the protective plate, so that personnel cannot directly contact the above structures, thereby solving the problem that when there is no circuit breaker body inside the circuit breaker installation compartment, personnel can arbitrarily open and close the valve assembly, which leads to an increase in electric shock accidents; the bottoms of the rotating plate 1 and the rotating plate 2 are both rotatably connected with a slide seat, and the bottoms of the rotating plate 1 and the rotating plate 2 are respectively slidably connected to the inner walls of the limit plate and the protective plate through the slide seat, and the rotating plate 2 is clamped with the top of the track through the slide seat rotatably connected at the bottom; The arc-shaped slide groove and the second rotating shaft have the same axis. When there is no object on the top of the track, the track is lifted up by the second spring, so that the track rotates upward with the second rotating shaft as the axis, and then the top of the avoidance groove close to the static contact pushes the second rotating plate to move. The first rotating plate and the second rotating plate are connected in an X-shaped rotation. When the second rotating plate slides upward through the inner wall of the slide seat located on the protective plate, the second rotating plate and the first rotating plate drive the limit plate to move to the side close to the second fixed plate, so that the limit plate moves between the two sets of rotating frames to limit the two sets of rotating frames. By limiting the two sets of rotating frames, the two sets of rotating frames are kept in a locked state. When the top of the track does not carry the circuit breaker body through the trolley component, the two sets of rotating frames are caused to move relative to each other due to external force, thereby further increasing the safety of the valve component.

[0017] 2. The GIS switch cabinet with a stable safety device is kept in a rotatable state through a belt through a plurality of rotating shafts three, and the up and down movement of the valve assembly is controlled by a pull rod and a rotating frame. When the limit plate is damaged, when the two sets of rotating frames are not limited by the limit plate, if a person moves the valve assembly, the friction force applied by the person to the valve assembly is converted into a sliding force through the rotating shaft three and the belt, thereby making the belt ring and the plurality of rotating shafts three rotate, while the valve frame remains stationary, thereby keeping the valve assembly isolated from the static contact.

[0018] 3. The GIS switch cabinet with a stable safety device monitors the temperature of the inner cavity of the switch cabinet through a temperature sensor, so that when the switch cabinet is in operation, if a high temperature abnormality caused by a short circuit occurs, the temperature sensor transmits the temperature data to the controller, and the controller controls the expansion joint to contract, so that the expansion joint cancels the limit of the rotating plate, thereby increasing the movable stroke of the card plate on the inner wall of the limit slide groove; When the trolley component moves toward the inner wall of the circuit breaker installation chamber, the end of the frame body abuts against the rubber plugging cover, thereby causing the rubber plugging cover to drive the spring 1 and the telescopic tube to contract; When the limit of the rotating plate by the telescopic device is cancelled, the elastic potential energy of the spring 1 is released, so that the spring 1 pushes the trolley component to move to the side away from the static contact through the rubber plugging cover, and then the trolley component drives the circuit breaker body to separate from the static contact, thereby avoiding further short circuit problems of the equipment; Since the clamping plate maintains a sliding relationship with the inner wall of the limiting slide groove, the clamping plate is limited by the limiting slide groove, so that when the spring pushes the trolley component to move to the side away from the static contact through the rubber plugging cover, after the trolley component drives the circuit breaker body to separate from the static contact, the trolley component can be limited by the clamping plate and the inner wall of the limiting slide groove away from the static contact side, thereby avoiding the problem of the trolley component being completely moved out of the inner wall of the circuit breaker installation compartment, which would cause further damage to the circuit breaker body.

A second rotating shaft 511 is fixedly mounted on the top of the end of the mounting plate 509 away from the static contact 7. The outer wall of the second rotating shaft 511 is rotatably connected to a track 512. A avoidance groove 513 is provided on the top of the track 512. An arc plate 515 is fixedly mounted on the outer wall of the avoidance groove 513 at one end close to the static contact 7.

A telescope 518 is embedded on the inner wall of the side of the limiting slide groove 503 away from the rotating groove 516. The outer wall of the telescopic end of the telescope 518 is in contact with the outer wall of the rotating plate 517, and the telescope 518 is located on the side of the rotating plate 517 away from the static contact 7.

[0027] In a preferred embodiment: the arc plate 515 is slidably sleeved on the inner wall of the arc chute 514, the top of the second spring 510 abuts against the bottom of the track 512, the top of the support seat 508 abuts against the bottom of the track 512, the bottom of the mounting plate 509 is fixedly assembled with the inner wall of the circuit breaker mounting compartment 2, and the arc chute 514 and the second rotating shaft 511 are coaxial; The rubber plugging cover 507 and the end portion of the frame body 401 correspond to each other.

[0028] In the above structure, the arc-shaped slide groove 514 and the second rotating shaft 511 are the same axis. When the top of the track 512 does not carry any items, the track 512 is lifted up by the second spring 510, so that the track 512 rotates upward with the second rotating shaft 511 as the axis, and then the top of the avoidance groove 513 close to the static contact 7 pushes the second rotating plate 613 to move, and then the second rotating plate 613 and the first rotating plate 612 drive the limiting plate 611 to move, so that the limiting plate 611 moves between the two groups of rotating frames 605 to limit the two groups of rotating frames 605. Here, the valve component 6 is only briefly described, and the specific operation process is shown below; The retractable end of the retractor 518 is used to limit the rotating plate 517, so that the trolley component 4 drives the circuit breaker body 3 to move into the circuit breaker installation chamber 2, and then the rotating shaft 1 403 is rotated by a tool so that the rotating shaft 1 403 drives the clamping plate 405 to engage with the rotating plate 517, so that the slide rail component 5 can limit the trolley component 4, thereby preventing the trolley component 4 from sliding out of the inner cavity of the circuit breaker installation chamber 2, resulting in the trolley component 4 driving the circuit breaker body 3 to separate from the static contact 7; The temperature of the inner cavity of the switch cabinet 1 is monitored by the temperature sensor 502, so that when the switch cabinet 1 is in operation, if a high temperature abnormality caused by a short circuit occurs, the temperature sensor 502 transmits the temperature data to the controller, and the controller controls the expansion joint 518 to contract, so that the expansion joint 518 cancels the limit of the rotating plate 517, thereby increasing the movable stroke of the clamping plate 405 on the inner wall of the limit sliding groove 503; When the trolley component 4 moves toward the inner wall of the circuit breaker installation chamber 2, the end of the frame 401 abuts against the rubber plugging cover 507, and then the rubber plugging cover 507 drives the spring 1 505 and the telescopic tube 506 to contract; When the limit of the rotating plate 517 by the telescopic device 518 is cancelled, the elastic potential energy of the spring 1 505 is released, so that the spring 1 505 pushes the trolley component 4 to move to the side away from the static contact 7 through the rubber plug 507, and then the trolley component 4 drives the circuit breaker body 3 to separate from the static contact 7, thereby avoiding further short circuit problems of the equipment; Since the clamping plate 405 maintains a sliding relationship with the inner wall of the limiting slide groove 503, the clamping plate 405 is limited by the limiting slide groove 503, so that the spring 1 505 pushes the trolley component 4 to move to the side away from the static contact 7 through the rubber plugging cover 507. After the trolley component 4 drives the circuit breaker body 3 to separate from the static contact 7, the trolley component 4 can be limited by the clamping plate 405 and the inner wall of the limiting slide groove 503 away from the static contact 7, thereby avoiding the problem that the trolley component 4 is completely moved out of the inner wall of the circuit breaker installation compartment 2, causing further damage to the circuit breaker body 3.

[0029] In a preferred embodiment: the valve component 6 includes two groups of valve assemblies 601 arranged vertically and two groups of fixed plates 604 and protective plates 609 arranged left and right, the inner walls of both sides of the valve assembly 601 are slidably sleeved with sliding rods 602, the outer walls of the sliding rods 602 are fixedly equipped with fixed blocks 603, the outer edges of the fixed plates 604 close to the valve assembly 601 are rotatably sleeved with two groups of rotating frames 605, the outer edges of the fixed plates 604 close to the valve assembly 601 are rotatably sleeved with torsion springs 607, the outer edges of the two groups of rotating frames 605 close to the valve assembly 601 and the push plate 301 are rotatably connected with a rotating wheel 606, the two groups of rotating frames 605 are rotatably connected to the side away from the push plate 301 with pull rods 608, and one end of the two groups of pull rods 608 are respectively rotatably connected to the two groups of rotating frames 605, and the other ends of the two groups of pull rods 608 are respectively rotatably connected to the outer walls of the same side of the two groups of valve assemblies 601.

[0030] In a preferred embodiment: a travel groove 610 is opened on the outer wall of the opposite part of the protective plate 609 and the push plate 301, a limit plate 611 is set on the side of the protective plate 609 close to the fixed plate 2 604, and a rotating plate 1 612 and a rotating plate 2 613 connected in an X-shape are set between the limit plate 611 and the protective plate 609.

[0031] In a preferred embodiment: the tops of the rotating plate 1 612 and the rotating plate 2 613 are rotatably connected to the protective plate 609 and the limiting plate 611 respectively, the bottoms of the rotating plate 1 612 and the rotating plate 2 613 are slidably sleeved with the inner walls of the protective plate 609 and the limiting plate 611 respectively, and the bottom of the rotating plate 2 613 is fixedly engaged with the bottom of the track 512; One end of the torsion spring 607 overlaps with the rotating frame 605 located in the top group, and the other end of the torsion spring 607 overlaps with the outer wall of the second fixing plate 604.

[0032] The slide bar 602, the fixing block 603, the fixing plate 604 and the protection plate 609 are all fixedly assembled with the inner wall of the circuit breaker installation compartment 2; In the above structure, the second fixing plate 604, the rotating frame 605, the rotating wheel 606, and the pull rod 608 are covered by the protective plate 609, so that personnel cannot directly contact the above structure, thereby solving the problem that when there is no circuit breaker body 3 inside the circuit breaker installation chamber 2, personnel can arbitrarily open and close the valve assembly 601, resulting in an increase in electric shock accidents; By providing a travel groove 610, when the trolley component 4 drives the circuit breaker body 3 and the push plate 301 moves towards the inner wall of the circuit breaker installation bin 2, the push plate 301 can move into the travel groove 610. Furthermore, the end of the push plate 301 abuts against the two sets of runners 606. Since the two sets of runners 606 are respectively rotatably connected to the ends of the two sets of rotating frames 605, and the two sets of rotating frames 605 are rotatably connected through the second fixing plate 604, the two sets of runners 606 drive the rotating frames 605 to rotate towards each other with the second fixing plate 604 as the axis. And since the two sets of pull rods 608 are rotatably connected to the ends of the two sets of rotating frames 605, the two sets of rotating frames 605 rotating towards each other drive the two sets of pull rods 608 to move upward and downward respectively; Thus, the two sets of pull rods 608 drive the two sets of valve components 601 to move upward and downward respectively on the outer wall of the slide rod 602; Among them, the rotating frame 605 of the bottom set is rotatably connected to the valve component 601 of the top set through a pull rod 608, and the rotating frame 605 of the top set is rotatably connected to the valve component 601 of the bottom - top set through a pull rod 608; Since the cross - section of the push plate 301 is in an inverted - U shape, after the upper and lower end portions of the push plate 301 abut against and push the two sets of runners 606, as the two sets of runners 606 rotate with the two sets of rotating frames 605 with the second fixing plate 604 as the axis, the distance between the two sets of runners 606 decreases. Furthermore, during the process of the push plate 301 pushing the runners 606, due to the change in the decreased distance of the two sets of runners 606, the two sets of runners 606 are clamped inside the inner wall of the push plate 301. Thus, the push plate 301 limits the runners 606, and further keeps the two sets of valve components 601 in the slid - out state; Sliding seats are rotatably connected to the bottoms of the first rotating plate 612 and the second rotating plate 613. The bottoms of the first rotating plate 612 and the second rotating plate 613 are respectively slidably connected to the inner walls of the limiting plate 611 and the protective plate 609 through the sliding seats, and the second rotating plate 613 is clamped to the top of the track 512 through the sliding seat rotatably connected to its bottom; Since the arc - shaped chute 514 and the second rotating shaft 511 share the same axis, when the top of the track 512 does not carry items, the spring two 510 jacks up the track 512, causing the track 512 to rotate upward with the second rotating shaft 511 as the axis. Furthermore, the top of the avoidance groove 513 close to the static contact 7 pushes the second rotating plate 613 to move. Using the X - shaped rotational connection between the first rotating plate 612 and the second rotating plate 613, when the second rotating plate 613 slides upward on the inner wall of the protective plate 609 through the sliding seat, the second rotating plate 613 and the first rotating plate 612 drive the limiting plate 611 to move towards the side close to the second fixing plate 604, and the limiting plate 611 moves between the two sets of rotating frames 605 to limit the two sets of rotating frames 605; By limiting the two sets of rotating frames 605, the two sets of rotating frames 605 remain in a locked state, so that when the top of the track 512 does not carry the circuit breaker body 3 through the trolley component 4, the two sets of rotating frames 605 are caused to move relative to each other due to external forces, thereby further increasing the safety of the valve component 6.

[0033] In a preferred embodiment: the valve assembly 601 includes a valve frame 6011 and a belt 6014, the inner wall of the valve frame 6011 is rotatably connected to a plurality of rotating shafts 6013, the outer walls on both sides of the valve frame 6011 are fixedly equipped with sliding frames 6012, and the belt 6014 is sleeved on the outer edges of the plurality of rotating shafts 6013.

[0034] In a preferred embodiment, the valve assembly 601 is slidably connected by the sliding frame 6012 and the sliding rod 602 , and the two sides of the valve frame 6011 are in contact with the outer walls of the two sets of protection plates 609 .

[0035] In the above structure, the belt 6014 is used to maintain a rotatable state through the plurality of rotating shafts 3 6013, and the up and down movement of the valve assembly 601 is controlled by the pull rod 608 and the rotating frame 605. When the limit plate 611 is damaged and the two sets of rotating frames 605 are not limited by the limit plate 611, if a person moves the valve assembly 601, the friction force applied by the person to the valve assembly 601 is converted into a sliding force through the rotating shaft 3 6013 and the belt 6014, thereby causing the belt 6014 to rotate around the plurality of rotating shafts 3 6013, while the valve frame 6011 remains stationary, thereby allowing the valve assembly 601 to maintain isolation from the static contact 7.

[0036] Working principle: a groove is provided on the inner wall of the circuit breaker installation chamber 2 at the relative position where the static contact 7 and the circuit breaker body 3 are plugged in; the groove is isolated by the valve assembly 601, so that the inner cavity of the circuit breaker installation chamber 2 is directly connected to the static contact 7 without passing through the groove; The retractable end of the retractor 518 is used to limit the rotating plate 517, so that the trolley component 4 drives the circuit breaker body 3 to move into the circuit breaker installation chamber 2, and then the rotating shaft 1 403 is rotated by a tool so that the rotating shaft 1 403 drives the clamping plate 405 to engage with the rotating plate 517, so that the slide rail component 5 can limit the trolley component 4, thereby preventing the trolley component 4 from sliding out of the inner cavity of the circuit breaker installation chamber 2, resulting in the trolley component 4 driving the circuit breaker body 3 to separate from the static contact 7; The temperature inside the switch cabinet 1 is monitored by the temperature sensor 502. When the switch cabinet 1 operates and there is a high-temperature anomaly caused by a short circuit, the temperature sensor 502 transmits the temperature data to the controller, and the controller controls the retraction of the telescopic device 518, canceling the limit of the rotating plate 517 by the telescopic device 518. As a result, the movable stroke of the clamping plate 405 on the inner wall of the limit chute 503 increases; When the trolley component 4 moves towards the inner wall of the circuit breaker installation bin 2, the end of the frame body 401 abuts against the rubber plug 507, causing the rubber plug 507 to drive the first spring 505 and the telescopic tube 506 to contract; When the telescopic device 518 cancels the limit of the rotating plate 517, the elastic potential energy of the first spring 505 is released. The first spring 505 pushes the trolley component 4 towards the side away from the static contact 7 through the rubber plug 507, causing the trolley component 4 to drive the circuit breaker body 3 to separate from the static contact 7, thereby avoiding further short-circuit problems of the equipment; Since the clamping plate 405 maintains a sliding relationship with the inner wall of the limit chute 503, through the limit of the clamping plate 405 by the limit chute 503, when the first spring 505 pushes the trolley component 4 towards the side away from the static contact 7 through the rubber plug 507, after the trolley component 4 drives the circuit breaker body 3 to separate from the static contact 7, the trolley component 4 can be limited by the inner wall of the limit chute 503 on the side away from the static contact 7 through the clamping plate 405 and the limit chute 503, thereby avoiding the problem that the trolley component 4 completely moves out of the inner wall of the circuit breaker installation bin 2, resulting in further damage to the circuit breaker body 3; Since the cross-section of the pushing plate 301 is in the shape of a "匚", after the upper and lower end parts of the pushing plate 301 abut against and push the two sets of rotating wheels 606, as the two sets of rotating wheels 606 rotate around the fixed plate two 604 with the two sets of rotating frames 605, the distance between the two sets of rotating wheels 606 is reduced. As a result, during the process of the pushing plate 301 pushing the rotating wheels 606, due to the change in the reduced distance between the two sets of rotating wheels 606, the two sets of rotating wheels 606 are clamped to the inner wall of the pushing plate 301, enabling the pushing plate 301 to limit the rotating wheels 606, and further enabling the two sets of valve components 601 to remain in the slid-out state; By providing the stroke groove 610, when the trolley component 4 drives the circuit breaker body 3 and the pushing plate 301 moves towards the inner wall of the circuit breaker installation bin 2, the pushing plate 301 can move into the stroke groove 610. As a result, the end of the pushing plate 301 abuts against the two sets of rotating wheels 606. Since the two sets of rotating wheels 606 are respectively rotatably connected to the ends of the two sets of rotating frames 605, and the two sets of rotating frames 605 are rotatably connected through the fixed plate two 604, the two sets of rotating wheels 606 drive the rotating frames 605 to rotate towards each other around the fixed plate two 604. And through the two sets of pull rods 608 being rotatably connected to the ends of the two sets of rotating frames 605, the two sets of rotating frames 605 rotating towards each other drive the two sets of pull rods 608 to move upward and downward respectively; At the same time, the bottoms of the rotating plate 1 612 and the rotating plate 2 613 are both rotatably connected with a slide seat, and the bottoms of the rotating plate 1 612 and the rotating plate 2 613 are respectively slidably connected with the inner wall of the limit plate 611 and the protective plate 609 through the slide seat, and the rotating plate 2 613 is clamped with the top of the track 512 through the slide seat rotatably connected at the bottom; The gravity of the circuit breaker body 3 and the trolley component 4 drives the rail 512 to move downward with the second rotating shaft 511 as the axis, so that the top of the avoidance groove 513 close to the static contact 7 drives the second rotating plate 613 to move downward, and the first rotating plate 612 and the second rotating plate 613 are connected in an X-shape rotation, so that when the second rotating plate 613 slides downward through the inner wall of the slide seat located on the protective plate 609, the second rotating plate 613 and the first rotating plate 612 drive the limit plate 611 to move away from the second fixed plate 604, so that the limit plate 611 moves to one side of the two sets of rotating frames 605; Thus, the two groups of pull rods 608 respectively drive the two groups of valve assemblies 601 located on the outer wall of the slide rod 602 to move upward and downward.
