Description

Technical Field

[0001] This utility model relates to the technical field of GGD low-voltage switchgear, and in particular to a GGD type low-voltage switchgear with a high-temperature resistant structure. Background Technology

[0002] With the rapid advancement of industrial automation, new energy industries, and infrastructure construction, power systems are placing higher demands on the reliability, stability, and adaptability of low-voltage switchgear. As a core piece of equipment in the power distribution field, the GGD type low-voltage switchgear, with its advantages of compact structure, safe operation, and convenient maintenance, is widely used in various scenarios such as factories, high-rise buildings, substations, and new energy power plants.

[0003] A search revealed a novel GGD low-voltage switchgear assembly (publication number: CN208445109U), comprising a switch cabinet body. A control panel is located on the top of the front housing of the switch cabinet body. An equipment mounting bracket is spirally fixed to the inner bottom of the front housing of the switch cabinet body. A first and second dust extraction pipes are symmetrically fixed to both sides of the mounting bracket, with their top and bottom ends connected via a dust removal pipe. In this invention, by providing an external switch mounting slot, the external switches of the GGD low-voltage switchgear assembly can be embedded and then sealed with a cover plate. This makes the external switches of the GGD low-voltage switchgear assembly concealed switches, preventing them from being exposed and protecting them. It also makes the GGD low-voltage switchgear assembly more aesthetically pleasing. Furthermore, the arc-shaped cover plate and V-shaped protective frame protect the control panel from damage during transportation.

[0004] However, in actual use, the above-mentioned solution cannot effectively dissipate the heat generated during device operation, and cannot effectively cool down the system. Furthermore, subsequent maintenance, such as cleaning internal heat dissipation components or replacing aging components, requires complete disassembly and reinstallation. This process is not only cumbersome and time-consuming, but also allows external dust to directly enter the device during component disassembly. Long-term accumulation of this dust can adhere to the surfaces of electrical components, potentially causing poor contact, short circuits, and other malfunctions, severely impacting the stable operation and lifespan of the device.

[0005] Therefore, this utility model provides a GGD type low-voltage switchgear with a high-temperature resistant structure. Utility Model Content

Positioning pins 304 are slidably connected to the inner wall of positioning holes 301. Positioning pins 304 are inserted into positioning holes 301 to position the parts inside the device. A pull-out dustproof component is installed inside the cabinet 1. The pull-out dustproof component includes two slide rails 3 fixedly connected to the inner side wall of the cabinet 1. The slide rails 3 serve as the sliding carrier. The slide rails 3 are equipped with a sliding component inside to realize the pull-out of the component. The moving end of the sliding component is equipped with a drawer 2 as the carrier of the device parts. A connecting rod 403 is rotatably connected to the inner wall of the cabinet 1. A dustproof component is installed outside the connecting rod 403 to connect the cabinet 1 and the dustproof component. A heat dissipation component is installed inside drawer 2 to dissipate heat from the heat absorption plate 203; Sleeve 502 is disposed on the outer side of the moving end of the sliding component. Sleeve 502 serves as a carrier for limiting the sliding component. An L-shaped groove 503 is provided on the outer wall of the middle section of sleeve 502 for limiting the movement. The engaging component, located inside the sleeve 502, is used to limit the movement of the sliding component.

[0019] The sliding assembly includes a slide bar 302 that is slidably connected inside the slide rail 3. The slide bar 302 slides inside the slide rail 3 to achieve pull-out. A support member 303 is fixedly connected to the top of the slide bar 302. The bottom wall of the support member 303 is fixedly connected to the drawer 2. The support member 303 is used to support and fix the top dustproof assembly and the bottom drawer 2. The inner liner of the cabinet 1 is made of stainless steel.

[0020] Reference Figure 3 , Figure 4 and Figure 7The dust-blocking assembly includes gears 401 fixedly connected to the outer walls of both ends of the connecting rod 403 and rack 4 fixedly connected to the top wall of the support member 303. The gears 401 and rack 4 are meshed together. The movement of the support member 303 causes the rack 4 to move, the rack 4 causes the gears 401 to rotate, and the gears 401 cause the connecting rod 403 to rotate. A dust-blocking plate 402 is fixedly connected to the outer wall of the middle section of the connecting rod 403. The connecting rod 403 causes the dust-blocking plate 402 to rotate.

[0021] Reference Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9 The heat dissipation assembly includes multiple filters 201 that are slidably connected to the inner side wall of the drawer 2, serving as a channel for the inflow of cold air and filtering the incoming cold air, and heat dissipation fins 202 that are fixedly connected to the top wall of the drawer 2 to increase the heat dissipation effect.

[0022] Reference Figure 9 The engaging assembly includes a spring 5 fixedly connected to the inside of the cabinet 1 and a limiting member 501 slidably connected to the inner wall of the sleeve 502. The limiting member 501 is used to limit the support member 303. A limiting post 504 is fixedly connected to the outer wall of the middle section of the limiting member 501. Pressing the limiting member 501 causes it to slide inside the sleeve 502 to the inside of the cabinet 1, thereby squeezing the spring 5. Then, rotating the limiting member 501 causes the limiting post 504 to engage with the L-shaped groove 503 to achieve the limiting.

[0023] Reference Figure 3 and Figure 6 A rubber layer is provided between the filter screen 201 and the drawer 2 to seal the drawer 2, making the device more airtight and dustproof.

[0024] Specifically, when using the GGD type low-voltage switchgear with high-temperature protection structure: first, start the three exhaust fans 101. Cold air enters the device through the filter screen 201 and is discharged from the exhaust fan 101, forming an internal and external air convection channel to accelerate heat dissipation; at the same time, the three filters 201 in the drawer 2 can filter dust in the air to prevent dust from entering the cabinet 1 and affecting the operation of the equipment. When drawer 2 needs to be pulled out, pull the handle on one side of drawer 2 to move the support 303. At the same time, slide the slide bar 302 along the slide rail 3 to pull out the drawer, which in turn moves the rack 4. During the pulling process, the rack 4 on the top wall of the support 303 drives the meshing gear 401 to rotate, which in turn causes the connecting rod 403 to rotate and open the dust baffle 402, thus preventing dust when the drawer 2 is opened. If it is necessary to fix the position of drawer 2, the positioning pin 304 can be inserted into the positioning hole 301 at the corresponding position until it penetrates into the slide rail 3 and abuts against the slide bar 302 to complete the positioning. When drawer 2 needs to be pushed back, push the handle on one side of drawer 2. The rack 4 drives the gear 401 to rotate in the opposite direction. The dust baffle 402 rotates upward and resets. The slide bar 302 and the support 303 slide and reset along the slide rail 3. Then press the limiting member 501 to make it slide in the sleeve 502. Press it until it is inserted into the cabinet 1 and squeezes the spring 5. Then rotate the limiting member 501 so that the limiting post 504 on the side wall is engaged in the L-shaped groove 503, thereby positioning the slide bar 302.
