Description

Technical Field

[0001] The present invention belongs to the technical field of switchgear, and in particular relates to an air-insulated medium-voltage switchgear with a buffering function. Background Art

[0002] The primary function of a switchgear is to open and close, control, and protect electrical equipment during power generation, transmission, distribution, and conversion in power systems. Switchgear can be installed indoors or outdoors as needed and is also widely used on ships. The components within a switchgear primarily include circuit breakers, disconnectors, load switches, operating mechanisms, transformers, and various protective devices. Switchgear can be categorized in many ways. For example, they can be divided into removable and fixed types based on the circuit breaker installation method; they can also be divided into open, metal-enclosed, and metal-clad types based on the cabinet structure; and they can be further categorized into high-voltage, medium-voltage, and low-voltage types based on voltage levels.

[0003] For example, the invention patent with application number 2021109932270 discloses a switch cabinet with a buffering and shock-absorbing function, comprising a support frame, a buffer mechanism disposed in the middle of the support frame, and a placement plate mounted on the buffer mechanism; the buffer mechanism comprises a sliding rod disposed on the support frame, a second telescopic spring and a sliding block sleeved on the sliding rod, a connecting rod hinged to the sliding block, and a connecting seat hinged to the end of the connecting rod away from the sliding block; the connecting seat is provided with a rotating shaft, the outer ring of the rotating shaft is sleeved with a torque spring, the end of the torque spring is fixed to the rotating shaft, and the middle of the torque spring abuts against the inner wall of the placement plate sleeved on the rotating shaft. A buffer mechanism is provided on the support frame, and a placement plate is mounted on the buffer mechanism. When a staff member places the switch cabinet body on the placement plate, the placement plate is supported by the buffer mechanism, thereby achieving buffering and shock absorption for the switch cabinet body, solving the problem of poor seismic resistance caused by the fixed contact between the bottom of the switch cabinet and the ground. However, when bumps or collisions occur, the switch cabinet as a whole is prone to tipping over, causing damage to the components inside the switch cabinet.

[0004] In addition, most switch cabinets have poor protection effects. External water can easily enter the cabinet and damage the internal components. The cabinet is also easily affected by external and internal factors, causing high temperatures to occur inside the cabinet, affecting the stability of the switch cabinet. In addition, dust in the external air can easily enter the cabinet and affect the service life of the internal components.

[0037] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0038] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0039] First embodiment

[0040] Reference Figure 1-7An air-insulated medium-voltage switchgear with a buffering function includes a switchgear body 1. Buffer components 2 are provided on both sides of the switchgear body 1. Heat dissipation grooves 103 are evenly opened on the back of the switchgear body 1. Specifically, the heat dissipation grooves 103 are used for heat dissipation inside the switchgear body 1.

[0041] The buffer assembly 2 includes a rotating rod 201, which is provided with two groups. The two groups of rotating rods 201 are symmetrically connected to the rotating shafts installed on both sides of the side of the switch cabinet body 1. The ends of the two groups of rotating rods 201 away from the switch cabinet body 1 are provided with support plates 202. The support plates 202 are "U"-shaped structures. Both ends of the support plates 202 are provided with sliding rods 203. The ends of the sliding rods 203 away from the support plates 202 slide and fit in the sliding holes 208 opened at the ends of the rotating rods 201. The outer side of the sliding rods 203 is sleeved with a first buffer spring 204. The cross sections of the sliding holes 208 and the sliding rods 203 are both "T"-shaped structures. Side openings 206 are symmetrically opened on both sides of the support plates 202. There are sockets 207 at both ends and at positions corresponding to the side openings 206 on both sides. Roller assemblies 5 are provided on the outer sides of both ends of the support plate 202. The roller assembly 5 includes a stud 501 threadedly inserted into the socket 207, and a universal wheel 502 is provided at the bottom end of the stud 501. Specifically, when the switch cabinet body 1 needs to be moved, the support plates 202 on both sides are rotated to a position located at the bottom surface of the switch cabinet body 1 by rotating the rotating rods 201 on both sides, thereby supporting the switch cabinet body 1. At this time, the universal wheels 502 on both sides of the bottom of the support plate 202 can be used to achieve overall movement, and when the support plate 202 is rotated to the bottom end of the switch cabinet body 1, the support plate 202 is always located at the bottom of the support column 302.

[0042] The four corners of the bottom surface of the switch cabinet body 1 are detachably connected with the support leg assembly 3, and the support leg assembly 3 includes a support cylinder seat 301 provided at the four corners of the bottom surface of the switch cabinet body 1, and a support column 302 is slidably fitted in the support cylinder seat 301, and a pad is provided at the bottom end of the support column 302. A second buffer spring 303 is provided between the top end of the support column 302 and the inner top surface of the support cylinder seat 301. The cross-sections of the support cylinder seat 301 and the support column 302 are both "T"-shaped structures. After moving the switch cabinet body 1 to the specified position, the rotating rods 201 on both sides are respectively rotated to the two sides of the switch cabinet body 1, so that the universal wheels 502 on both sides can be rotated from the bottom of the switch cabinet body 1 to the two sides respectively. At the same time, the support column 302 contacts the ground through the pad at the bottom to prevent the switch cabinet body 1 from moving, and the second buffer spring 303 is used to achieve shock absorption and buffering when the switch cabinet body 1 is stationary.

[0043] When the device of this embodiment is in use, when the switch cabinet body 1 is moved, the rotating rods 201 on both sides are rotated, and the support plates 202 on both sides are rotated to the position located at the bottom surface of the switch cabinet body 1, so that the switch cabinet body 1 can be supported. At this time, the universal wheels 502 on both sides of the bottom of the support plates 202 can be used to achieve overall movement. During the movement, when the switch cabinet body 1 vibrates due to bumps, the sliding rod 203 and the sliding hole 208 are used to slide together, and under the action of the first buffer spring 204, the switch cabinet body 1 can be buffered and shock-absorbed.

[0044] After the switch cabinet body 1 is moved to the designated position, the rotating rods 201 on both sides are rotated to the two sides of the switch cabinet body 1 respectively, so that the universal wheels 502 on both sides can be rotated from the bottom of the switch cabinet body 1 to the two sides respectively. At the same time, the support column 302 contacts the ground through the pad at the bottom to prevent the switch cabinet body 1 from moving, and the second buffer spring 303 is used to achieve shock absorption when the switch cabinet body 1 is stationary.

[0045] Second embodiment

[0046] Reference Figure 8-11 In the case of an air-insulated medium-voltage switchgear with a buffering function provided in the first embodiment, during actual use, when the amplitude of the bumps is large, the switchgear body 1 is prone to violent shaking and tipping over, thereby causing damage to the interior of the switchgear body 1. In addition, when the switchgear is used outdoors, especially in rainy and snowy weather, rain, snow, and moisture can easily enter the interior of the switchgear body 1 through the heat dissipation slots 103, causing damage to the internal components of the switchgear body 1. In addition, under strong sunlight in summer, the internal temperature of the switchgear body 1 can easily rise, thereby affecting the operating stability of the internal components of the switchgear body 1. In addition, in dusty weather, sand and dust in the air can easily enter the interior of the switchgear body 1, thereby affecting the service life of the internal components of the switchgear body 1. In order to solve the above problems:

[0047] A driving assembly 6 for driving the buffer assembly 2 is provided on the side of the switch cabinet body 1. The driving assembly 6 includes a support 601 provided on the side of the switch cabinet body 1. An electric push rod 602 is provided on the bottom surface of the support 601. A rack 603 is provided at the bottom telescopic end of the electric push rod 602. Meshing teeth are provided on both sides of the rack 603. The ends of the rotating shafts on both sides are fixedly sleeved with gears 604. The opposite sides of the gears 604 on both sides are respectively engaged with the two sides of the rack 603. Specifically, the rack 603 is driven to rise and fall by the extension and contraction of the electric push rod 602, and the meshing teeth on both sides of the rack 603 are respectively engaged with the gears 604 on both sides, thereby driving the rotation of the side rotating shaft, thereby realizing the rotation of the rotating rods 201 on both sides, avoiding manual rotation and saving labor.

[0048] A protective component 4 is provided on the buffer components 2 on both sides, and the protective component 4 includes a mounting groove 401, which is opened inside the support plate 202, and the inner side of the mounting groove 401 is rotatably connected to a reel 402, and a protective shield 403 is wound on the outer side of the reel 402. The material of the protective shield 403 is rainproof and sun-proof fabric, and a side groove 404 is opened on the side of the mounting groove 401. One end of the protective shield 403 passes through the side groove 404 and is fixedly connected to an electromagnet 405, and both ends of the reel 402 are provided with a spiral spring 406, and the two ends of the spiral spring 406 are respectively fixedly connected to the side of the mounting groove 401 and the reel 402. Specifically, the protective component 4 can switch to different modes according to different weather conditions, thereby achieving effective protection of the switch cabinet body 1.

[0049] A climate monitoring module 101 and a tilt sensor 102 are provided on the side of the switch cabinet body 1. Specifically, the climate monitoring module 101 is used to monitor external climate changes, including changes in weather such as temperature and sunlight intensity. The tilt sensor 102 is used to monitor the status of the switch cabinet body 1 in real time. When the switch cabinet body 1 tilts, timely monitoring and feedback are facilitated.

[0050] When the device of this embodiment is in use, when the switch cabinet body 1 is moved, the contraction of the electric push rod 602 drives the rack 603 to move upward, so that the rotating rods 201 on both sides are synchronously dropped under the action of the gears 604 on both sides until the universal wheel 502 is rotated to the bottom of the switch cabinet body 1. The switch cabinet body 1 can be pushed to achieve the overall movement. After the movement is completed, the electric push rod 602 is extended to extend the support plates 202 on both sides of the bottom of the switch cabinet body 1 to both sides of the switch cabinet body 1.

[0051] During use on board, when the hull experiences significant pitching, the switch cabinet body 1 subsequently experiences significant shaking, and the tilt sensor 102 detects a change in the angle of the switch cabinet body 1. When the tilt sensor 102 detects that the tilt angle of the switch cabinet body 1 is greater than a set threshold value of the tilt sensor 102, it is actively determined that the switch cabinet body 1 is about to tip over, and the electric push rod 602 is activated at this time, and the electric push rod 602 is extended to drive the rack 603 to move downward, thereby realizing the separation of the rotating rods 201 on both sides, and making the bottom end of the support plate 202 coplanar with the bottom surface of the switch cabinet body 1, as shown in FIG. Figure 11As shown, the rotating rods 201 on both sides can be used to support the switch cabinet body 1 when the switch cabinet body 1 is tilted, thereby effectively preventing the switch cabinet body 1 from tipping over and protecting the switch cabinet body 1. When the rotating rod 201 and the support plate 202 on one side support the switch cabinet body 1, the rotating rod 201 compresses the first buffer spring 204 downward, thereby further buffering the switch cabinet body 1, reducing shock on the switch cabinet body 1, and further protecting the switch cabinet body 1.

[0052] In addition, during use on the hull, when the environment around the switch cabinet body 1 is cleaned and the environment is cleaned with water, dust will float in the air, and dust and water will easily enter the switch cabinet body 1. Therefore, when cleaning, the electric push rod 602 is first started, and the extension of the electric push rod 602 is used to rotate the support plates 202 on both sides to the top of the switch cabinet body 1. At this time, the distance between the support plates 202 on both sides is the shortest, and because the support plates 202 on both sides are at the top of the switch cabinet body 1, the electromagnets 405 on the support plates 202 on both sides are exactly aligned. At the same time, the electromagnets 405 on the sides of the support plates 202 on both sides are started, so that the electromagnets 405 on both sides generate magnetism and make the magnetic poles of the electromagnets 405 on both sides opposite to each other, thereby realizing the mutual attraction of the electromagnets 405 on both sides, and at the same time, the electric push rods 602 are contracted, thereby driving the support plates 202 on both sides of the top of the switch cabinet body 1 to separate from each other, and the protective shielding 403 wound on the reel 402 can be stretched out. At this time, the vortex springs 406 at both ends are contracted, and the electric push rods 602 are used to adjust the rotating rods 201 on both sides to a vertical state. At this time, the protective shielding 403 on both sides are in a state as shown in FIG. Figure 10 In the state shown, the front and rear sides of the switch cabinet body 1 are completely wrapped to prevent external water and dust from entering the interior of the switch cabinet body 1. After cleaning and rinsing, the electromagnet 405 is turned off, the spiral spring 406 is reset, and the protective shields 403 on both sides are re-stored.

[0053] In addition, when the switch cabinet body 1 is used on a ship or outdoors, when the temperature sensor inside the switch cabinet body 1 detects that the internal temperature is higher than the threshold value set by the temperature sensor, the electric push rod 602 is activated to adjust the rotating rods 201 on both sides to the position as shown in FIG. Figure 11The position shown is then determined, and the electric push rod 602 is then extended and retracted in a large range, thereby realizing the swinging of the protective shields 403 on both sides, thereby accelerating the flow of air on both sides of the switch cabinet body 1, realizing the heat dissipation of the switch cabinet body 1, and at the same time accelerating the speed at which the heat inside the switch cabinet body 1 is discharged from the heat dissipation groove 103, realizing the heat dissipation inside the switch cabinet body 1. When the temperature sensor inside the switch cabinet body 1 detects that the internal temperature is lower than the threshold value set by the temperature sensor, the electromagnet 405 is turned off, the spiral spring 406 is reset, and the protective shields 403 on both sides are re-stored.

[0054] Furthermore, when the switch cabinet body 1 is used outdoors, the climate monitoring module 101 detects that it is about to rain or snow, and uses the electric push rod 602 to rotate the rotating rods 201 on both sides to the position as shown in FIG. Figure 8 In the state shown, the protective shields 403 on both sides are partially stretched out and cover the top of the switch cabinet body 1. Since the protective shield 403 is made of rainproof fabric, it can shield the switch cabinet body 1 from rain and prevent rainwater from entering the front and back sides of the switch cabinet body 1 and causing damage to internal components.

[0055] It is worth noting that since rainy and snowy days are often accompanied by strong winds, the protective shields 403 on both sides should not be stretched too long. If stretched too long, the wind-exposed area of ​​the protective shields 403 will increase, and under the action of wind, the protective shields 403 on both sides will overcome the magnetic attraction between the two electromagnets 405 and separate, and thus will not be able to protect against rain and snow. Therefore, in the state of protecting against rain and snow, the most appropriate angle between the rotating rod 201 and the side of the switch cabinet body 1 is between 30° and 60°.

[0056] In addition, when the climate monitoring module 101 detects that the light intensity is greater than the threshold value set by the climate monitoring module 101, the electric push rod 602 is started, and the electric push rod 602 is used to adjust the rotating rods 201 on both sides to the above-mentioned rain and snow protection state, and then the electric push rod 602 continues to retract, thereby driving the rotating rods 201 on both sides to continue to fall, until the rotating rods 201 on both sides rotate to the horizontal state. At this time, the distance between the support plates 202 on both sides reaches the maximum, and at the same time, the protective shielding 403 on both sides is in the state as shown in FIG. Figure 9 The state shown in FIG. 1 can achieve sunshade for the switch cabinet body 1 , thereby preventing strong light from causing the temperature inside the switch cabinet body 1 to rise and affecting the normal operation of the switch cabinet body 1 .

[0057] It should be noted that, due to the high outside temperature at this time, if the rotating rods 201 on both sides continue to rotate downward after rotating to the horizontal state, the protective shielding 403 will continue to be stretched. As the height of the protective shielding 403 decreases, it will gradually block the heat dissipation slots 103 on the back side of the switch cabinet body 1 and the corresponding heat dissipation ports on the front side, affecting the flow of internal air, thereby affecting the heat dissipation effect of the switch cabinet body 1. Therefore, the rotating rods 201 on both sides are rotated to the horizontal state. Figure 9 The horizontal position shown is the optimal position, that is, the rotating rod 201 is perpendicular to the side surface of the switch cabinet body 1.

[0058] In addition, when the climate monitoring module 101 detects that sandstorm weather is about to occur, the rotating rods 201 on both sides are adjusted to the positions shown in FIG. Figure 9 After the state shown, the electric push rod 602 is used to drive the rotating rods 201 on both sides to continue to move downward until the rotating rods 201 on both sides are in a vertical state. At this time, the protective shielding 403 on both sides is in a state as shown. Figure 10 In the state shown, the protective shields 403 on both sides are tightly fitted with the top and side surfaces of the switch cabinet body 1, thereby completely wrapping the front and back sides of the switch cabinet body 1, thereby effectively preventing sand and dust from entering the switch cabinet body 1 and affecting the service life of the internal components of the switch cabinet body 1.

[0059] In addition, after the climate monitoring module 101 detects that the sandstorm weather has ended, a lot of dust will adhere to the outside of the protective shield 403, which will affect the service life of the protective component 4 over time. Then, after the sandstorm weather ends, the electric push rod 602 is made to perform a high-frequency micro-extension movement, thereby realizing a high-frequency separation and contraction cycle of the support plates 202 on both sides, and then the switch cabinet body 1 can be vibrated up and down, so that most of the dust attached to the outside of the protective shield 403 can be shaken off, and the protective shield 403 can be cleaned. When protection is not needed, the electromagnets 405 on both sides are turned off to make the electromagnets 405 lose their magnetism, so that the protective shields 403 on both sides are separated and rewound on the reel 402 under the action of the reset of the spiral spring 406.

[0060] Therefore, the present invention can use the electric push rod 602 to drive the rotating rods 201 on both sides to support the switch cabinet body 1 when the switch cabinet body 1 is about to fall, thereby preventing the switch cabinet body 1 from falling. During use on the hull, the electric push rod 602 is used to wrap the protective shield 403 on both sides of the switch cabinet body 1 to prevent external water and dust from entering the interior of the switch cabinet body 1, and the electric push rod 602 is used to swing the protective shield 403 on both sides to achieve heat dissipation outside and inside the switch cabinet body 1. In addition, during outdoor use, when encountering rainy or snowy days, the electromagnets 405 on both sides are attracted to each other, and the protective shield 403 is moved by the rotating rods 201 on both sides. 03 is partially stretched to achieve rain and snow protection for the switch cabinet body 1, to prevent rain and snow from entering the interior and causing damage to components. In addition, in weather with strong light intensity, the protective shielding 403 on both sides can be stretched to a sufficient length by using the electric push rod 602 to adjust the rotating rod 201 to a horizontal state, thereby achieving sunshade for the switch cabinet body 1 and preventing high temperature from occurring inside the switch cabinet body 1 and affecting normal work. In addition, in dusty weather, the protective shielding 403 on both sides is fully stretched out by the electric push rod 602 to achieve complete wrapping of the front and back sides of the switch cabinet body 1, thereby preventing sand and dust from entering the interior of the switch cabinet body 1 and affecting the service life of the internal components.

[0061] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
