Description
Technical Field
[0001] This invention relates to the field of power cabinet technology for Class II medical facilities, and in particular to an integrated power cabinet for Class II medical facilities. Background Technology
[0002] In the electrical design of medical facilities, Class II medical facilities have extremely high requirements for power supply safety and continuity. In these facilities, patients are often under anesthesia or connected to life support equipment, and even a small leakage current can pose a risk of micro-electric shock. To meet this special need, existing power cabinets in Class II medical facilities generally adopt medical-grade isolated power supply systems, using isolation transformers to reduce ground leakage current and ensure power supply safety. However, existing integrated power cabinets still have many shortcomings in practical use: Electrical components inside the cabinet are prone to generating arcs or sparks during normal use or fault disconnection, especially during short-circuit faults. In such cases, the arc energy is large, which may not only burn out electrical components but also pose a fire risk. Although there are existing gas-insulated or arc-extinguishing solutions for high-voltage switchgear, these structures are complex and costly, making them difficult to apply directly to the compact space of low-voltage power supply cabinets in medical settings. Furthermore, when a short-circuit fault occurs in a certain electrical component, the traditional approach is to rely on circuit breakers or fuses to disconnect the faulty circuit. While this method can protect the line, it directly leads to a power outage for that circuit. In Class II medical facilities, even if a branch circuit experiences a short circuit, it is essential to ensure the continuity of the overall power supply as much as possible to avoid harming patients due to power outages. This increases the risk of electrical component burnout.
[0003] In addition, the main heat-generating component inside the cabinet, the isolation transformer, experiences a significant temperature rise during high-power operation. If heat dissipation is inadequate, it will not only affect the transformer's lifespan but may also trigger a fault arc. Therefore, we propose an integrated power cabinet for Class II medical facilities. Summary of the Invention
[0004] In order to overcome the technical problems existing in the prior art, the present invention provides an integrated power supply cabinet for Class II medical facilities.
[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: including a cabinet, a partition is fixedly installed on the inner side of the cabinet, a transformer is fixedly installed on the inner bottom wall of the cabinet, an installation assembly and an electrical component assembly are installed on the upper side of the partition, and an auxiliary assembly is installed on the side of the partition; The installation assembly includes two sets of movable frames. The sides of the movable frames are provided with constraint frames and guide plates. The sides of the guide plates are provided with flow guiding components, which deliver protective gas into the cabinet and centrally deliver it into the guide plate. The other side of the guide plate is provided with installation components, which further centrally guide the protective gas. The electrical component assembly includes a clip frame.

The circuit switching component connects the circuit by connecting the first copper plate and the second copper plate. In case of a short circuit, it switches to connect the other first copper plate and the second copper plate.
[0006] Furthermore, the two sets of movable frames are mirror images of each other inside the cabinet, and the constraint frames are mirror images of each other fixedly installed on the top wall and upper side of the partition inside the cabinet. The side of the constraint frame is provided with a through groove corresponding to the position of the movable frame. The guide plate is fixedly installed on the inner side of the movable frame. The side of the guide plate is provided with openings through it at equal intervals. A plug is installed inside the opening. A pull strip is fixedly connected between the side of the plug and the inner side of the guide plate.
[0007] Furthermore, the flow guiding component includes a connecting pipe symmetrically and fixedly installed through the side of the guide plate, and the connecting pipe extends out through the inside of the slide groove. A guide pipe is fixedly installed on the upper side of the cabinet, and a limiting block is fixedly installed on the inner side of the outlet of the guide pipe, and the limiting block extends elastically into the corresponding connecting pipe.
[0008] Furthermore, the mounting component includes a mounting plate positioned between the sides of the guide plate, with drainage grooves extending through it on the upper and lower sides of the mounting plate, a drainage block inside the mounting plate extending through the mounting plate to the corresponding inside of the guide plate, a first spring fixedly connected between the side of the drainage block and the inside of the mounting plate, the first spring being movably sleeved on the side of the drainage block, and a sliding rod fixedly mounted on the side of the drainage block, the sliding rod being slidably mounted inside the drainage groove.
[0009] Furthermore, the buckle frame is fixedly installed on the side of the mounting plate, two sets of disconnect switches are symmetrically snapped and fixedly installed on the side of the buckle frame, and the power conversion switch is snapped and installed on the side of the buckle frame corresponding to the position between the two sets of disconnect switches. The output terminals of the two sets of disconnect switches are connected in series with the power conversion switch through wires, and the branch electrical components are snapped and fixedly installed on the side of the buckle frame.
[0010] Furthermore, the first copper plate is disposed on the lower side of the power conversion switch, and the second copper plate is disposed on both sides of the branch electrical components. The output terminal of the power conversion switch is fixedly connected to the side of the first copper plate through the copper plate, and the output and input terminals of the branch electrical components are fixedly connected to the corresponding second copper plate through the copper plate.
[0011] Furthermore, the circuit switching component includes a mounting bracket disposed on the side of the branch electrical component and fixed between the movable brackets by screws. A slot is provided through the side of the mounting bracket, and a conductive copper frame is provided on the side of the mounting bracket. The conductive copper frame is attached to the side of the corresponding first copper plate and second copper plate. A connecting block is fixedly installed on the side of the conductive copper frame and is slidably disposed inside the slot. A fuse is fixedly installed through the side of the mounting bracket. A second spring is fixedly connected between the side of the connecting block and the wall of the slot. A linkage rod is fixedly installed between the sides of the connecting blocks.
[0012] Furthermore, the auxiliary component includes connection holes symmetrically opened on the side of the partition. A connecting cylinder is fixedly installed on the upper side of the partition corresponding to the position of the connection hole. A heat-conducting rod is symmetrically and fixedly installed through the side of the transformer and extends to the position of the connection hole. A heat-conducting element is fixedly installed on the upper side of the heat-conducting rod. A blocking plate is fixedly installed on the upper side of the heat-conducting element and is snapped onto the side of the connecting cylinder.
[0013] Compared with the prior art, the beneficial effects that this invention can achieve are: 1. This invention constructs a gas path frame inside the cabinet by setting up installation components, including a movable frame, a guide plate, a connecting pipe, and a guide tube. Protective gas enters the guide plate through the guide tube and connecting pipe, and is then discharged through the drainage channel to the contact position of the first copper plate, the second copper plate, and the conductive copper frame. This achieves precise arc extinguishing protection at the connection points of electrical components, effectively suppresses arc generation, reduces the risk of electrical component burnout and fire, and improves the operational safety of the power cabinet.
[0014] 2. This invention employs a linkage structure consisting of a conductive copper frame, a connecting block, a fuse, a second spring, and a linkage rod. When a short circuit occurs in a circuit, the corresponding fuse melts due to heat, the second spring releases its tension, and the connecting block slides. Simultaneously, the linkage rod drives all conductive copper frames to switch to the position of another set of copper plates connected. This automatically switches the circuit path when a short circuit occurs, ensuring uninterrupted operation of the power cabinet. It overcomes the drawbacks of traditional fuses that directly cut off the power supply and meets the requirements for continuous power supply in Class II medical facilities.
[0015] 3. This invention incorporates auxiliary components, including a heat-conducting rod, a bimetallic heat-conducting element, and a blocking plate. When the transformer operates at high power and the temperature rises excessively, the heat-conducting rod transfers heat to the heat-conducting element. The heat-conducting element expands due to heat, pushing the blocking plate away from the connecting cylinder. This allows the protective gas above the partition to automatically flow into the space below the partition, providing auxiliary arc-extinguishing protection for the transformer. This prevents the transformer from malfunctioning due to overheating and improves the overall reliability and service life of the power cabinet.
[0016] 4. The movable frame, guide plate and mounting plate of this invention can be slidably mounted on the constraint frame. During maintenance, the whole assembly can be pulled out to the cabinet opening position, while the connecting pipe remains connected to the guide pipe outlet. This ensures that the protective gas can still be concentratedly supplied to the electrical components during the maintenance operation, avoiding electric sparks caused by disassembly and maintenance, and improving the safety and convenience of equipment maintenance.

[0019] To make the technical means, creative features, and achieved objectives and effects of this invention easier to understand, the invention is further described below with reference to specific embodiments. However, the following embodiments are merely preferred embodiments of this invention and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described herein without creative effort are all within the protection scope of this invention. Unless otherwise specified, the experimental methods in the following embodiments are conventional methods, and the materials and reagents used in the following embodiments are commercially available unless otherwise specified.
[0020] Example: Figure 1 and Figure 2 As shown, an integrated power cabinet for Class II medical facilities includes a cabinet body 1. A partition 11, which is rectangular, is fixedly installed on the inner side of the cabinet body 1. A transformer 12 is fixedly installed on the bottom wall inside the cabinet body 1. The transformer 12 reduces the leakage current to ground and prevents micro-electric shock. An installation assembly 2 and an electrical component assembly 3 are installed on the upper side of the partition 11. The installation assembly 2 forms an overall gas circuit frame and supplies protective gases such as nitrogen to the electrical components. The electrical component assembly 3 can switch circuits. An auxiliary assembly 4 is installed on the side of the partition 11. The auxiliary assembly 4 can use protective gas to provide auxiliary protection for the transformer 12.
[0021] like Figures 2 to 7As shown, the mounting assembly 2 includes two sets of movable frames 21, which are mirror images of each other inside the cabinet 1, corresponding to the upper side of the partition 11. A constraint frame 22 is mirror-fixed on the top wall inside the cabinet 1 and on the upper side of the partition 11, respectively. The constraint frame 22 is an "L"-shaped plate. A through-slot 221 is provided on the side of the constraint frame 22 corresponding to the position of the movable frame 21. The slot 221 is a rectangular groove. A guide plate 23 is fixedly installed inside the movable frame 21. The guide plate 23 is a hollow rectangular plate. The guide plate 23 has equidistant through holes 231 on its side. The holes 231 are circular. A plug 232 is installed inside the hole 231. The plug 232 is a convex circular block. A pull strip 233 is fixedly connected between the side of the plug 232 and the inside of the guide plate 23. The pull strip 233 is an elastic rectangular strip. A connecting pipe 24 is symmetrically fixedly installed through the side of the guide plate 23 and extends out through the inside of the slide groove 221. The connecting pipe 24 is a hollow circular pipe. A guide tube 25 is fixedly installed on the side. The guide tube 25 is a four-part round tube. The outlet of the guide tube 25 corresponds to the two ends of the slide groove 221. The inlet of the guide tube 25 is connected to the protective gas supply module. A limit block 251 is fixedly installed on the inner side of the outlet of the guide tube 25 and the limit block 251 extends elastically into the corresponding connecting tube 24. The limit block 251 is an elastic arc block. Specifically, the movable frame 21 can slide on the side of the constraint frame 22. The connecting tube 24 slides inside the slide groove 221 to constrain it. When in use, the movable frame 21 slides into the internal position of the cabinet 1. At this time, the connecting tube 24 is correspondingly squeezed and deformed by the limit block 251 so that it returns to its original position and extends into the internal position of the connecting tube 24. The connecting tube 24 can then be constrained and limited by the limit block 251. Subsequently, the protective gas delivered by the guide tube 25 can be guided to the corresponding position inside the guide plate 23 for protection. During maintenance, the movable frame 21 slides to the outlet position of the cabinet 1. The connecting tube 24 is correspondingly constrained to the outlet of the guide tube 25 to ensure the centralized supply of protective gas during maintenance. A mounting plate 26 is provided between the sides of the guide plate 23. The mounting plate 26 is a hollow rectangular plate. Drainage grooves 261, rectangular grooves, are provided through the mounting plate 26 on its upper and lower sides. A drainage block 27 is provided inside the mounting plate 26, extending through the mounting plate 26 to the corresponding interior of the guide plate 23. The drainage block 27 fits and compresses the plug block 232. The drainage block 27 is a convex cylindrical block with hollowed-out sides and equidistant circular holes on its sides. A first spring 271 is fixedly connected between the side of the drainage block 27 and the inner side of the mounting plate 26, and the first spring 271 is movably sleeved on the side of the drainage block 27. A sliding rod 2 is fixedly mounted mirror-image on the side of the drainage block 27. 8. The slide rod 28 is slidably installed inside the drainage channel 261. The slide rod 28 is a "T"-shaped cylindrical rod. Specifically, the mounting plate 26 is placed between the guide plates 23. The slide rod 28 slides inside the drainage channel 261, and the slide rod 28 can drive the drainage block 27 to slide into the mounting plate 26. After the slide rod 28 is released, the drainage block 27 extends out of the mounting plate 26 under the elastic pull of the first spring 271. The drainage block 27 inserts into the corresponding guide plate 23 and squeezes the block 232 out of the guide plate 23. The block 232 is deformed by the pull bar 233. At this time, the protective gas inside the guide plate 23 can flow into the mounting plate 26 through the drainage block 27, and the protective gas can be discharged from the drainage channel 261.
[0022] like Figures 6 to 10As shown, the electrical component assembly 3 includes a clip-on frame 31, which is fixedly installed on the side of the mounting plate 26. Two sets of disconnect switches 32 are symmetrically clipped and fixedly installed on the side of the clip-on frame 31. A power conversion switch 33 is provided between the sides of the two sets of disconnect switches 32 and is clipped and fixedly installed on the side of the clip-on frame 31. The two sets of disconnect switches 32 are respectively connected to the main power supply and the backup power supply. The output terminals of the two sets of disconnect switches 32 are connected in series with the power conversion switch 33 through wires. The power conversion switch 33 has an automatic switching function and can switch according to the voltage status signal of the main power supply. Branch circuit electrical components 34 are clipped and fixedly installed on the other sides of the mounting plate 26 by the clip-on frame 31. A first copper plate 35, which is a long rectangular plate, is provided on the lower side of the power conversion switch 33. Second copper plates 36 are provided on both sides of the branch electrical components 34. The output terminal of the power conversion switch 33 is fixedly connected to the side of the first copper plate 35 via copper plates. The output and input terminals of the branch electrical components 34 are fixedly connected to the corresponding second copper plates 36 via copper plates. The second copper plates 36 are shorter rectangular plates used for connection between the branch electrical components 34. A mounting bracket 37 is provided on the side of the branch electrical components 34 and is fixed to the movable brackets 21 by screws. The mounting bracket 37 is a rectangular plate made of insulating material. A through slot 371 is provided on the side of the mounting bracket 37. The slot 371 is rectangular. A convex-shaped slot is provided on the side of the mounting bracket 37, and a conductive copper frame 38 is provided on the side of the mounting bracket 37. The conductive copper frame 38 is attached to the side of the corresponding first copper plate 35 and second copper plate 36, realizing the circuit connection of the first copper plate 35, the second copper plate 36 and the adjacent second copper plate 36. The conductive copper frame 38 is a convex plate. A connecting block 381 is fixedly installed on the side of the conductive copper frame 38 and is slidably disposed inside the slot 371. The connecting block 381 is a rectangular block made of copper. A fuse 382 is fixedly installed through the side of the mounting bracket 37 and passes through the connecting block 381 to constrain it. A second spring 383 is fixedly connected between the side of the connecting block 381 and the wall of the slot 371. A linkage rod 39 is fixedly installed. The linkage rod 39 is a "C"-shaped rod. Specifically, during normal use, the power conversion switch 33 switches to connect the first set of isolating switches 32. At this time, the mounting bracket 37 is installed in the position between the movable brackets 21. The conductive copper bracket 38 on the side of the mounting bracket 37 is inserted into the side of the first copper plate 35 and the second copper plate 36, so as to realize the circuit connection of the first copper plate 35, the second copper plate 36 and the adjacent second copper plate 36. In the default state, the connecting block 381 is limited and constrained by the fuse 382. The connecting block 381 pulls the second spring 383 to stretch and deform, thus completing the connection of the overall circuit. The protective gas is discharged through the drainage groove 261, which can provide arc extinguishing protection for the first copper plate 35 and the second copper plate 36.In case of an abnormal short circuit, a short circuit occurs at either the second copper plate 36 or the first copper plate 35. The conductive copper frame 38 and the connecting block 381 generate heat, causing the corresponding fuse 382 to melt and break. At this time, the second spring 383 pulls the connecting block 381, causing the conductive copper frame 38 to slide into the other side of the first copper plate 35. Simultaneously, the other fuses 382 are pulled and break via the linkage rod 39, switching the circuit connection between the corresponding first copper plate 35 and second copper plate 36, as well as the adjacent second copper plate 36. This ensures uninterrupted power while switching the electrical component circuit, relieving the pressure on the short-circuited electrical components.
[0023] like Figure 2 , Figure 11 and Figure 12 As shown, auxiliary component 4 includes connecting holes 41, which are symmetrically opened on the side of partition 11. Connecting holes 41 are circular. A connecting cylinder 42, a cylindrical block, is fixedly installed on the upper side of partition 11 corresponding to the connecting holes 41. A heat-conducting rod 43 is symmetrically and fixedly installed through the side of transformer 12, extending to the connecting holes 41. A heat-conducting element 44, composed of a bimetallic strip, is fixedly installed on the upper side of the heat-conducting rod 43, conforming to the principle of thermal expansion and contraction. A blocking plate 45 is provided and snapped onto the side of the connecting cylinder 42. The blocking plate 45 can seal the connecting cylinder 42. Specifically, when the transformer 12 is operating at high power, the transformer 12 generates heat, which is conducted to the heat-conducting element 44 through the heat-conducting rod 43. The latter expands and deforms due to heat, which can push the blocking plate 45 away from the side of the connecting cylinder 42. At this time, the protective gas above the partition plate 11 can flow from the connecting cylinder 42 to the position below the partition plate 11 to provide arc extinguishing protection for the transformer 12, avoid the transformer 12 from having an accident, and ensure the uninterrupted normal operation of the power cabinet.
[0024] Working principle: Installation before use: First, assemble the frame and slide the slide bar 28 inside the drainage groove 261, so that the drainage block 27 slides completely into the mounting plate 26. Then, place the corresponding mounting plate 26 between the guide plates 23. Release the slide bar 28, and the drainage block 27 extends out of the mounting plate 26 under the elastic force of the first spring 271. The drainage block 27 is inserted into the corresponding guide plate 23, squeezing the block 232 away from the guide plate 23. The pull bar 233 is deformed and constrained by the block 232. In this way, the mounting plate 26 and the guide plate 23 are connected through the drainage block 27. Then, the mounting plate 26, the guide plate 23 and the movable frame 21 can slide in a position constrained by the constraint frame 22. The connecting pipe 24 slides in the groove 221 to the outlet position of the corresponding guide pipe 25. After the connecting pipe 24 squeezes the corresponding limit block 251 and deforms, it returns to its original position. The connecting pipe 24 can be fixed under the elastic constraint of the limit block 251. The second step is the installation of electrical components and wiring. After the installation plate 26 is completed, the disconnect switch 32, power conversion switch 33 and branch electrical component 34 are installed in sequence on the side of the corresponding clip frame 31. Then, the corresponding first copper plate 35 and second copper plate 36 are set on the side of the power conversion switch 33 and branch electrical component 34 through copper plates. The second copper plate 36 and the second copper plate 36 and their adjacent second copper plates 36 are kept at a distance. At this time, the mounting frame 37 is set between the movable frames 21. The conductive copper frame 38 on the side of the mounting frame 37 can be inserted and attached to the position between the corresponding first copper plate 35 and second copper plate 36 and their adjacent second copper plate 36. The conductive copper frame 38 connects the contacting first copper plate 35 or second copper plate 36, so that the corresponding disconnect switch 32, power conversion switch 33 and branch electrical component 34 complete the circuit connection. The connecting block 381 is held by the deformation of the second spring 383 due to the limit pull of the fuse 382. In use: First step, in normal state, connect to power. By default, the circuit of the first set of isolating switches 32 is turned on by rotating the power conversion switch 33. At this time, the first copper plate 35, the conductive copper frame 38 and the second copper plate 36 conduct electricity. The left side branch electrical component 34 is in the circuit connected and is connected to the transformer 12 to reduce leakage to ground. The protective gas is introduced into the cabinet 1 above the partition 11 inside the synchronous guide tube 25. The protective gas corresponding to the outlet section of the guide tube 25 is introduced into the guide plate 23 through the connecting tube 24, and then flows through the diversion block 27 to the mounting plate 26 and is discharged from the diversion groove 261. This concentrates the protective gas at the contact position of the first copper plate 35, the second copper plate 36 and the conductive copper frame 38 for arc extinguishing protection. The second step is to handle abnormal situations. When the main power supply is abnormal, the power conversion switch 33 can automatically control the switching to the second set of isolating switches 32 for use. In addition, when a short circuit occurs in the circuit, heat is generated at the contact points of the corresponding first copper plate 35, second copper plate 36 and conductive copper frame 38. The heat conduction of the connecting block 381 causes the corresponding fuse 382 to melt and break. At this time, the second spring 383 can pull the connecting block 381 to slide inside the mounting bracket 37. Through the linkage rod 39, all connecting blocks 381 move synchronously. The tension stored in the second spring 383 is then released, pulling the remaining fuses 382 to break as well. All conductive copper frames 38 then slide to the right side of the first copper plate 35, completing the circuit connection of the first copper plate 35, the second copper plate 36 on the right side and the adjacent second copper plate 36. The third step is auxiliary protection. When the transformer 12 is used at high power, the heat-conducting rod 43 conducts heat to the transformer 12, causing the corresponding heat-conducting element 44 to expand due to heat and push the blocking plate 45 to detach from the connecting cylinder 42. This allows the protective gas above the partition 11 to flow into the position below the partition 11, providing arc-extinguishing protection for the transformer 12 and preventing it from being damaged due to high power use.
[0025] During subsequent maintenance, the movable frame 21, guide plate 23 and mounting plate 26 are directly pulled to slide as a whole. The connecting pipe 24 slides inside the slide groove 221 to guide the movable frame 21. In the maintenance state, the connecting pipe 24 is connected to the outlet of the corresponding guide pipe 25. At this time, the protective gas can still be concentrated and discharged to the side of the first copper plate 35, the second copper plate 36 and the conductive copper frame 38, thus avoiding sparks during maintenance.
[0026] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
