Description

Technical Field

[0001] This invention relates to the field of switchgear, specifically to an intelligent armored withdrawable metal-enclosed switchgear. Background Technology

[0002] Switchgear is a general term for electrical equipment used in power systems for controlling, protecting, isolating and connecting circuits. It is mainly used for the distribution and management of electrical energy. Switchgear is a type of switchgear and is an integrated set of equipment that typically includes components such as switchgear, protection devices, monitoring instruments, busbars and cable connectors.

[0003] Armored switchgear is a metal-enclosed switchgear with a structural design that provides high mechanical strength, protection level, and safety. It is suitable for medium and high voltage power distribution systems. The main electrical components are installed in metal compartments, and each functional unit is isolated from the others. The outer shell and partitions are armored with metal, and the steel plates provide high mechanical strength and protection. In the event of a fire inside the switchgear, a gas extinguishing system is required for timely fire suppression. This system uses inert or chemical gases to smother the flames and prevent electrical conduction and residue. However, gas extinguishing systems are usually installed on the top or side wall of the switchgear. When a fire occurs, the nozzles release gas directly. But the electrical equipment inside the switchgear is often installed separately, and equipment far from the nozzles is easily blocked by other equipment. The gas then reaches the more distant equipment the slowest, making it impossible to extinguish the fire in time. Summary of the Invention

[0004] The purpose of this invention is to provide an intelligent armored withdrawable metal-enclosed switchgear to solve the problems mentioned in the background art.

[0008] Preferably, the oxygen barrier mechanism includes two symmetrically arranged mounting cavities inside the cabinet. A driven rod is rotatably mounted inside the mounting cavity, and a positioning rod extends to the inside of the mounting cavity. A transmission chain is rotatably mounted between the driven rod and the adjacent positioning rod, and the size of the transmission wheel on the driven rod is smaller than that on the positioning rod. A cam is fixedly mounted on the outside of the driven rod. A top plate located above the cam is slidably mounted inside the mounting cavity. Two symmetrically distributed pull rods are fixedly mounted at the bottom of the top plate. A sealing plate is fixedly mounted between the two pull rods. A sliding cavity for limiting the sliding of the sealing plate is opened inside the cabinet. Ventilation holes of the same size are opened on the outside of the cabinet and the outside of the sealing plate. Two symmetrically distributed first springs are fixedly mounted between the top plate and the top inner wall of the mounting cavity.

[0009] Preferably, the wiring mechanism includes an insert plate disposed on the outside of the partition, the insert plate being fixedly connected to the inside of the cabinet via two support plates. The outside of the partition has an insertion cavity for the insert plate to be inserted and positioned. The outside of the partition has multiple equally spaced insertion holes. A first clamping plate is fixedly installed inside each insertion hole. One side of the insert plate has multiple equally spaced second clamping plates, the number of which is the same as the number of the first clamping plates. A sliding plate is fixedly installed on the side of each second clamping plate away from the first clamping plate. The partition plate has a groove on its outer side for the slider to slide in a limited position. A second spring is fixedly installed between the slider and the inner side of the groove.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] This invention uses an adjustable plate mechanism to separate and install multiple sets of electrical equipment using multiple partitions. When a short circuit occurs and fire breaks out in the electrical equipment, the multiple partitions move in a stepped manner to stagger the electrical equipment, thus solving the problem of electrical equipment obstruction. The temperature sensor can activate the gas storage tank, enabling the nozzles to extinguish the fire on the electrical equipment on the partitions in a timely manner, thereby achieving a precise fire extinguishing effect.

[0018] This invention utilizes an oxygen-blocking mechanism that, during the swinging of the rotating plate, a cam pushes the top plate upward, and the top plate pulls the sealing plate to move synchronously. This causes the vent holes on the sealing plate to be misaligned with the vent holes on the cabinet, sealing the cabinet and blocking oxygen from entering, thereby improving fire extinguishing efficiency.

[0019] This invention utilizes a cable-setting mechanism, allowing electrical equipment cables to pass through insertion holes on a partition. The elasticity of a second spring causes a second clamping plate to press the cable against a first clamping plate. This achieves adaptive positioning based on the quantity and width of the cable. During the partition's movement, a triangular abutment block presses against a triangular push block on a slider, positioning the slider and allowing the second clamping plate to release the cable, preventing cable pulling and improving the neatness of cable installation for easier future maintenance.

[0029] 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.

[0030] Example 1: Please refer to Figures 1-8 The diagram illustrates an intelligent armored removable metal-enclosed switchgear, comprising a cabinet 1 and multiple partitions 2 arranged vertically and equidistantly on the inner side of the cabinet 1. Equipment mounting plates 33 are fixedly installed on the outer sides of the partitions 2, and these mounting plates 33 have a U-shaped structure for easy installation of multiple electrical devices. A gas storage tank 3 is fixedly installed on the top of the cabinet 1, and multiple equally spaced nozzles 4 are fixedly installed on the bottom of the gas storage tank 3. A temperature sensor 5 is fixedly installed on the bottom of the gas storage tank 3. When the cabinet 1 rises due to a short circuit and fire caused by electrical equipment, the temperature sensor 5 activates the gas storage tank 3, causing inert gas to be injected into the cabinet 1 through the nozzles 4 to extinguish the fire in the electrical equipment. The switchgear also includes: an adjustment mechanism for aligning the multiple partitions 2 with the nozzles 4, installed on the inner side of the cabinet 1; an oxygen barrier mechanism for sealing and blocking oxygen in the cabinet 1, installed on the inner side of the cabinet 1; and a cable positioning mechanism for neatly positioning the cables of the electrical equipment, installed on the outer side of the partitions 2.

[0031] The adjustment mechanism includes two symmetrically rotating positioning rods 6 mounted on the inner side of the cabinet 1. A rotating plate 7 is fixedly mounted on the outer side of the positioning rods 6. A partition 2 is located between the two rotating plates 7. A first sliding rod 8 is rotatably mounted at both ends of the partition 2. A long groove is provided on the outer side of the rotating plate 7 for the first sliding rod 8 to slide within a limited position. A sleeve 9 is fixedly mounted on the outer side of the first sliding rod 8 and slidably mounted on the outer side of the rotating plate 7. Two pulley rods 10 are rotatably mounted at both ends of the partition 2. A groove for the pulley rods 10 is fixedly mounted on the inner side of the cabinet 1. The guide rail 11 with zero limit sliding allows the rotating plate 7 to move through the elongated groove and sleeve 9 to push the first sliding rod 8 when it swings. The first sliding rod 8 drives the partition 2 to move synchronously, so that the pulley rods 10 at both ends of the partition 2 move along the corresponding guide rail 11. The partition 2 can then move horizontally. Moreover, the further away the partition 2 is from the positioning rod 6, the greater the movement distance, so that multiple partitions 2 are distributed in a stepped manner, which facilitates the nozzle 4 to spray air to extinguish the electrical equipment on the bottom partition 2. A metal block 12 is fixedly installed at one end of the positioning rod 6. Two symmetrically distributed electromagnets 13 are fixedly installed on the inside of the cabinet 1. The two electromagnets 13 are in contact with the two metal blocks 12 respectively, and the electromagnets 13 are connected to the cabinet 1 through a controller. When the fire is extinguished and the power is cut off inside the cabinet 1, the controller cuts off the power supply from the cabinet 1 to the electromagnets 13, so that the electromagnets 13 cannot attract the metal blocks 12. Two symmetrically distributed arc-shaped supports 14 are fixedly installed on the inside of the cabinet 1. The two rotating plates 7 are not slid through each other, and an arc spring 15 is fixedly installed between one end of the arc bracket 14 and the outer side of the rotating plate 7. When the electromagnet 13 is de-energized, the rebound force of the arc spring 15 can be used to pull the rotating plate 7 to swing along the outer side of the arc bracket 14 with the positioning rod 6 as the fulcrum, so as to adjust the position of multiple partitions 2. A limit ring 34 is fixedly installed on the outer side of the first slide rod 8. A limit groove is opened in the long groove of the rotating plate 7 for the limit ring 34 to limit the sliding, thereby improving the stability of the movement of the first slide rod 8.

[0032] Example 2: Please refer to Figures 3-5This embodiment further illustrates Example 1. The oxygen barrier mechanism shown in the figure includes two symmetrically arranged mounting cavities 16 inside the cabinet 1. A driven rod 17 is rotatably mounted inside the mounting cavity 16. A positioning rod 6 extends to the inside of the mounting cavity 16. A transmission chain 18 is rotatably mounted between the driven rod 17 and the adjacent positioning rod 6. The size of the transmission wheel on the driven rod 17 is smaller than the size of the transmission wheel on the positioning rod 6, so that when the positioning rod 6 rotates, it can drive the driven rod 17 to rotate 90 degrees through the transmission chain 18. The outer side of the driven rod 17... A cam 19 is fixedly installed, and a top plate 20 located above the cam 19 is slidably installed inside the mounting cavity 16. When the driven rod 17 rotates, it can push the top plate 20 upward through the cam 19. Two symmetrically distributed pull rods 21 are fixedly installed at the bottom of the top plate 20, and a sealing plate 22 is fixedly installed between the two pull rods 21. A sliding cavity for limiting the sliding of the sealing plate 22 is opened on the inner side of the cabinet 1, so that when the top plate 20 moves, it can pull the sealing plate 22 upward along the inner side of the sliding cavity through the pull rods 21. The outer side of the cabinet 1 is connected to... The outer side of the sealing plate 22 is provided with vent holes of the same size. When the sealing plate 22 is aligned with the vent holes on the cabinet 1, it can provide ventilation and heat dissipation for the electrical equipment inside the cabinet 1. When the top plate 20 moves upward, the vent holes on the sealing plate 22 can be offset from the vent holes on the cabinet 1, so that the sealing plate 22 seals the vent holes on the cabinet 1, thereby sealing and blocking oxygen in the cabinet 1 and improving the fire extinguishing efficiency. Two symmetrically distributed first springs 23 are fixedly installed between the top plate 20 and the top inner wall of the mounting cavity 16, so that the cam 19 During the swing reset, the rebound force of the first spring 23 can be used to quickly reset the top plate 20, which makes it easy for the sealing plate 22 to open the vent on the cabinet 1. A dust cover 35 is fixedly installed on the outside of the vent on the cabinet 1 to ensure heat dissipation inside the cabinet 1 while providing a shield against external dust. Two symmetrically distributed guide plates 36 are fixedly installed at the bottom of the top plate 20. The cam 19 is located between the two guide plates 36 to guide the rotation of the cam 19, prevent the cam 19 from being misaligned with the top plate 20, and ensure the normal pushing of the top plate 20.

[0033] Example 3: Please refer to Figures 2-8This embodiment further illustrates other embodiments. The wiring mechanism shown in the figure includes an insertion plate 24 disposed on the outside of the partition 2. The insertion plate 24 is fixedly connected to the inside of the cabinet 1 through two support plates. The outside of the partition 2 has an insertion cavity for the insertion plate 24 to be inserted and positioned. The outside of the partition 2 has a plurality of equally spaced insertion holes. The cables of electrical equipment fixed on the partition 2 can be inserted into the insertion holes, which facilitates the positioning and separation of the cables of electrical equipment. A first clamping plate 25 is fixedly installed on the inside of the insertion hole. A plurality of equally spaced second clamping plates 26 are disposed on one side of the insertion plate 24, and the number of second clamping plates 26 is the same as the number of first clamping plates 25. The second clamping plates 26 are far from the first clamping plates 25. A slider 27 is fixedly installed on one side away from the first clamping plate 25. A groove is provided on the outer side of the insertion plate 24 for the slider 27 to slide within a limited position. A second spring 28 is fixedly installed between the slider 27 and the inner side of the groove. Utilizing the elasticity of the second spring 28, the second clamping plate 26, in conjunction with the first clamping plate 25, elastically clamps the cable inserted into the insertion hole, achieving neat positioning of the cable. Triangular push blocks 29 are fixedly installed on both sides of the slider 27. A moving groove is provided on the inner side of the groove of the insertion plate 24 for the triangular push blocks 29 to slide within a limited position. An elastic slide bar 30 is slidably installed on the inner side of the moving groove. Multiple equidistant triangular abutments 31 are fixedly installed on the side of the elastic slide bar 30 near the slider 27, allowing... When the slider 27 moves, it can drive the triangular push block 29 to contact the triangular abutment block 31, causing the triangular push block 29 to push the triangular abutment block 31 to move. The triangular abutment block 31 can compress the elastic slider 30. A stop rod 32 is slidably installed on the inner side of the moving groove. The stop rod 32 is fixedly installed in the cavity of the partition 2, so that the stop rod 32 can push the triangular abutment block 31 to move. When the insertion plate 24 is inserted into the cavity of the partition 2, the stop rod 32 can contact the triangular abutment block 31, causing the triangular abutment block 31 to move away from the triangular push block 29. The second clamping plate 26 can elastically clamp the cable, and when the partition 2 moves, the partition 2 can drive the stop rod 32 to move away from the triangular abutment block 31, utilizing the elastic slider The rebound force of strip 30 causes triangular abutment 31 to abut against triangular push block 29, providing positioning for second clamping plate 26, allowing second clamping plate 26 to loosen the cable and preventing cable pulling. Multiple guide rods 37 are fixedly installed on the side of insert plate 24 near the first clamping plate 25. Insertion holes for limiting insertion of guide rods 37 are opened inside the cavity of partition plate 2, and the end of guide rod 37 away from insert plate 24 has an arc-shaped structure, which makes it easy for the cavity of partition plate 2 to be smoothly fitted on the outside of insert plate 24. Positioning strips 38 are fixedly installed on both sides of slider 27. Positioning grooves for limiting sliding of positioning strips 38 are opened in the slide groove of insert plate 24, improving the stability of slider 27 movement.

[0034] Working principle: First, the operator installs the electrical equipment on the equipment mounting plate 33 on the partition 2 and passes the cable through the insertion hole. Utilizing the elasticity of the second spring 28, the slider 27 pushes the second clamping plate 26 against the outside of the cable. The second clamping plate 26, in conjunction with the first clamping plate 25, elastically clamps the cable inserted into the insertion hole, achieving neat positioning of the cable. When a short circuit and fire occurs in the electrical equipment inside the cabinet 1, the cabinet 1 cuts off the power to the electromagnet 13 via the controller. The electromagnet 13 then stops attracting the metal block 12. Using the rebound force of the arc spring 15, one end of the arc spring 15 pulls the rotating plate. 7. The rotating plate 7 swings along the outer side of the arc-shaped bracket 14 with the positioning rod 6 as the fulcrum. The rotating plate 7 pulls the first sliding rod 8 to move through the long groove. In addition, the rotating plate 7 pulls the sleeve 9 to move, so that the sleeve 9 and the first sliding rod 8 move along the outer side of the rotating plate 7 and the inner side of the long groove, respectively. The first sliding rod 8 drives the partition 2 to move. The pulley rods 10 at both ends of the partition 2 move along the corresponding guide rails 11, so that the partition 2 is in a horizontal state. The multiple partitions 2 are distributed in a stepped state. At the same time, the insertion cavity of the partition 2 moves along the outer side of the insertion plate 24, so that the partition 2 drives the abutment rod 32 to move synchronously. The abutment rod 32 moves away from the triangular abutment block 31. Utilizing the rebound force of the elastic slider 30, the elastic slider 30 pushes the triangular abutment 31 closer to the triangular push block 29 on the outside of the slider 27. The triangular abutment 31 then abuts against the triangular push block 29, thus positioning the slider 27. As the partition 2 moves, the second clamping plate 26 releases the cable, preventing cable pulling during the movement of the partition 2. Simultaneously, the rotating plate 7 drives the positioning rod 6 to rotate synchronously. The positioning rod 6 drives the driven rod 17 to rotate 90 degrees via the transmission chain belt 18, causing the driven rod 17 to drive the cam 19 to rotate synchronously. The convex edge of the cam 19 pushes the top plate 20 upward, and the top plate 20 moves upward by pulling... Rod 21 pulls sealing plate 22 along the sliding cavity inside cabinet 1, causing sealing plate 22 to be misaligned with the vent on cabinet 1. Sealing plate 22 can then seal the vent on cabinet 1, preventing external oxygen from entering cabinet 1 and improving fire extinguishing efficiency. Finally, temperature sensor 5 detects that the temperature inside cabinet 1 is high, and temperature sensor 5 can then activate gas storage tank 3, causing gas storage tank 3 to inject inert gas into nozzle 4. Nozzle 4 can then directly spray gas to extinguish the fire on the electrical equipment on partition 2, solving the problem of obstruction between electrical equipment, thereby achieving precise fire extinguishing effect and improving the safety of cabinet 1.
