Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of pre-assembled electrical cabinets, and particularly relates to a pre-assembled electrical cabinet and a mounting method. BACKGROUND

[0002] The pre-assembled electrical cabinet, also known as a distribution box, is a cabinet body integrating electrical energy distribution components, protection devices and measurement devices. The currently common pre-assembled electrical cabinet mainly comprises a cabinet body, electrical components, a protection and control system and wiring components.

[0003] Among them, the cabinet body of most pre-assembled electrical cabinets in the prior art is usually welded from a cold-rolled steel plate, and the internal wiring components are also fixedly connected in a bolted or welded manner. Although this kind of way can realize the pre-assembly of the electrical cabinet and the assembly and protection of various electrical components, the effect of preventing collision and heat dissipation protection of the various electrical components inside the pre-assembled electrical cabinet is poor in actual application, so that the various electrical components inside the pre-assembled electrical cabinet are easily damaged by external impact and environmental temperature and humidity during use, and the applicability and protection reliability of the pre-assembled electrical cabinet are poor.

[0004] Therefore, in view of the above technical problems, it is necessary to provide a pre-assembled electrical cabinet and a mounting method. SUMMARY

[0005] The purpose of the present application is to provide a pre-assembled electrical cabinet and a mounting method, which can significantly improve the applicability and protection reliability of the pre-assembled electrical cabinet.

[0006] In order to achieve the above-mentioned purpose, the technical scheme provided by an embodiment of the present application is as follows: A pre-assembled electrical cabinet, comprising: a cabinet body, a buffer isolation mechanism, an anti-collision flow guide mechanism and a backflow bearing mechanism.

[0007] The buffer isolation mechanism is fixedly arranged in the cabinet body and is used for adjustable buffer assembly of the wiring end. The buffer isolation mechanism comprises a power distribution rack, an adjustable assembly component and a pair of buffer fixing components. The adjustable assembly component is fixedly arranged in the power distribution rack, and the pair of buffer fixing components are assembled on the upper and lower sides of the power distribution rack respectively, and are used for insulation protection, buffer fixing and limiting and auxiliary flow guide heat dissipation of the power distribution rack.

[0008] The anti-collision flow guide mechanism is fixedly arranged on the outside of the power distribution rack and is used for anti-collision protection and flow guide heat dissipation protection of the power distribution rack. The anti-collision flow guide mechanism comprises a shielding protection component and an anti-collision flow guide protection component. The shielding protection component is fixedly arranged above the cabinet body, and the anti-collision flow guide protection component is fixedly arranged between the power distribution rack and the cabinet body and is used for anti-collision buffer and flow guide heat dissipation protection of the power distribution rack.

[0009] The backflow bearing mechanism is fixedly arranged below the cabinet body, and is used for bottom supporting, dust filtering and guiding, and auxiliary heat dissipation of the cabinet body.

[0010] In one or more embodiments of the present application, the cabinet body comprises a cabinet frame, a cabinet door and a plurality of side plates, the cabinet door is hingedly assembled on one side of the cabinet frame, and the plurality of side plates are boltedly assembled on the outside of the cabinet frame.

[0011] In one or more embodiments of the present application, the adjustable assembly component comprises a plurality of groups of fixed bottom plates, a pair of assembly side plates and a plurality of groups of power distribution loading plates.

[0012] In one or more embodiments of the present application, a plurality of assembly bolt holes are evenly distributed on the pair of assembly side plates.

[0013] In one or more embodiments of the present application, the buffer type fixing component comprises clamping fixing plates, insulating buffer pads, a plurality of groups of buffer springs, exhaust plates and a plurality of damping exhaust holes.

[0014] In one or more embodiments of the present invention, multiple sets of buffer springs are fixedly disposed within the insulating buffer pad. The insulating buffer pad can be supported and reset by the contraction and reset of the multiple sets of buffer springs. The exhaust plate is connected to the insulating buffer pad, allowing internal air to be discharged along the exhaust plate when the insulating buffer pad contracts. Multiple damping exhaust holes are evenly distributed on the side of the clamping and fixing plate close to the distribution frame. The diameter of one end of each damping exhaust hole within the clamping and fixing plate is larger than the diameter of the other end, and all multiple damping exhaust holes are connected to the exhaust plate. This results in the exhaust velocity being greater than the intake velocity under the action of the diameter, causing the insulating buffer pad to slowly recover its expansion state after contraction and exhaust, thus providing a buffering and shock-absorbing effect on the distribution frame.

[0015] In one or more embodiments of the present invention, the shielding and protection assembly includes a top cabinet, a pair of air guide pipes, a pair of dust filters, multiple sets of cooling fans, and a guide cone. The top cabinet is fixedly installed on the top of the cabinet body. The top cabinet provides shielding and protection for the top of the cabinet body. The pair of air guide pipes are symmetrically arranged on both sides of the top cabinet, and the pair of dust filters are fixedly installed on the side of the top cabinet close to the air guide pipes. The dust filters provide dust protection for the air intake of the air guide pipes. The multiple sets of cooling fans are respectively fixedly connected to one end of the pair of air guide pipes located inside the top cabinet. By controlling the operation of the multiple sets of cooling fans, outside air can be transported into the top cabinet along the guide cone, thereby accelerating the air circulation speed inside the cabinet and ensuring the heat dissipation effect of the pre-assembled electrical cabinet. The guide cone is fixedly installed at the center of the top cabinet, and the guide cone is inverted cone shape. The guide cone limits and guides the airflow inside the top cabinet.

[0016] In one or more embodiments of the present invention, the anti-collision and airflow guiding protection assembly includes an inner cabinet, multiple sets of buffer baffles, multiple sets of dust filter media, multiple sets of thermally conductive media, and an electrically operated louvered air inlet assembly. The inner cabinet is fixedly sleeved on the outside of the electrical distribution frame. The inner cabinet serves to assemble and fix the mounting plate. The multiple sets of buffer baffles are fixedly disposed on the outside of the inner cabinet, and the multiple sets of buffer baffles are reciprocated by bending to form filter media cavities close to the inner cabinet and thermally conductive media cavities close to the cabinet.

[0017] In one or more embodiments of the present invention, multiple sets of the dust filter packing and the heat-conducting packing are respectively filled in the filter packing cavity and the heat-conducting packing cavity. The inner cabinet has multiple evenly distributed guide holes in the part that contacts the filter packing cavity. The buffer baffle plate has multiple ventilation holes. The multiple filter packing cavities and the heat-conducting packing cavities are connected through the ventilation holes. The electric louver air inlet assembly is set in the clamping and fixing plate located above, and is used to control the ventilation status of the clamping and fixing plate.

[0018] An installation method for a pre-assembled electrical cabinet includes the following steps: S1. During the assembly of the pre-assembled electrical cabinet, a pair of clamping and fixing plates are fixedly connected to the inner cabinet to clamp and fix the distribution frame. The vertical height and horizontal position of the distribution loading plate can be adjusted according to actual needs. S2. Subsequently, multiple sets of buffer baffles are fixedly installed on the side of the inner cabinet, and multiple sets of dust filter packing and heat conduction packing are filled into the filter packing cavity and heat conduction packing cavity respectively. Through the cooperation of the top cabinet and the return flow bearing mechanism, the top and bottom of the cabinet can be sealed and protected, thus completing the assembly process of the pre-assembled electrical cabinet. S3. In practical applications, various electrical components can be assembled and fixed using several sets of power distribution loading plates. Furthermore, the distribution frame can be insulated and buffered through the cooperation of clamping plates, insulating buffer pads, and buffer springs. S4. When the distribution frame is subjected to external impact, the distribution frame will apply force to the insulating buffer pad, causing multiple sets of buffer springs to be compressed under the action of external force. As a result, the insulating buffer pad will shrink synchronously with the shaking of the distribution frame. When the insulating buffer pad shrinks under the action of external force, the air inside the insulating buffer pad will be discharged along the exhaust plate and damping exhaust hole. The shrinkage and reset of the insulating buffer pad provides buffer and anti-collision protection for the distribution frame. In addition, the exhaust method through multiple sets of damping exhaust holes will accelerate the air circulation outside the distribution frame, which will play an auxiliary role in heat dissipation protection for the electrical components installed inside the distribution frame. S5. In addition, the top cabinet provides top protection for the cabinet, and the baffle plate, multiple sets of dust filter packing and multiple sets of heat-conducting packing provide anti-collision buffer protection for the distribution rack. Furthermore, by controlling the operation of multiple sets of cooling fans, outside air is delivered into the cabinet, and the electrical components inside the distribution rack are ventilated and cooled by supplying air into the cabinet. S6. In addition, the air inside the top cabinet will be transported laterally into the cabinet body after being heated or filtered by multiple sets of dust filter packing and heat-conducting packing. At the same time, the heat dissipation stability of the pre-assembled electrical cabinet is ensured by the heat conduction effect of the buffer baffle and dust filter packing. S7. The bottom of the cabinet is supported and limited by the return flow bearing mechanism. The air inside the cabinet is discharged through the dust filtration of the return flow bearing mechanism, so as to ventilate and dissipate heat in the cabinet and clean the dust filter with air blowing.

[0019] Compared with the prior art, the pre-assembled electrical cabinet and installation method disclosed in this invention can protect various electrical components from collision and provide ventilation and heat dissipation protection by setting up a buffer isolation mechanism and an anti-collision diversion mechanism, which significantly improves the effect of protecting various electrical components from collision and heat dissipation. This greatly reduces the adverse effects of environmental factors and external forces on pre-assembled electrical cabinets, and significantly improves the applicability and protection performance of pre-assembled electrical cabinets.

Detailed Implementation

[0023] To enable those skilled in the art to better understand the technical solutions in this disclosure, the technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments in this disclosure, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this disclosure.

[0024] like Figures 1 to 13 As shown, a pre-assembled electrical cabinet in one embodiment of the present invention includes: a cabinet body 1, a buffer isolation mechanism 2, an anti-collision diversion mechanism 3, and a return current carrying mechanism 4. In practical applications, the buffer isolation mechanism 2 can provide insulated assembly and limiting for various electrical components, avoiding the risk of leakage in the distribution cabinet and improving safety. Simultaneously, it can provide buffering and ventilation protection for various electrical components. Furthermore, the anti-collision diversion mechanism 3 and the return current carrying mechanism 4 can shield and seal the upper and lower ends of the cabinet body 1 and provide heat dissipation protection.

[0025] like Figure 1 As shown, the cabinet 1 includes a frame 101, a door 102, and several side panels 103. The door 102 is hinged to one side of the frame 101. The side panels 103 are bolted to the outside of the frame 101. The frame 101, door 102, and side panels 103 together form the power distribution cabinet. The opening and closing of the power distribution cabinet can be controlled by opening and closing the door 102. The ability to disassemble the side panels 103 facilitates the inspection and maintenance of the buffer baffle 307, multiple sets of dust filter media 308, and multiple sets of heat-conducting media 309, improving the convenience of inspection and maintenance of the power distribution cabinet.

[0026] like Figures 3 to 4As shown, the buffer isolation mechanism 2 is fixedly installed inside the cabinet 1 and is used for adjustable buffer assembly of the wiring terminals. The buffer isolation mechanism 2 includes a distribution frame 201, adjustable assembly components, and a pair of buffer fixing components. The distribution frame 201 is fixedly installed inside the cabinet 1 and is used to assemble and fix several sets of distribution mounting plates 204.

[0027] like Figures 3 to 4 As shown, the adjustable assembly is fixedly installed within the power distribution frame 201. The adjustable assembly includes several sets of fixed base plates 202, a pair of assembly side plates 203, and several sets of power distribution loading plates 204. The several sets of fixed base plates 202 are symmetrically fixed in pairs within the power distribution frame 201. The fixed base plates 202 assemble, fix, and guide the pair of assembly side plates 203.

[0028] like Figures 3 to 4 As shown, a pair of mounting side plates 203 are slidably disposed between several sets of fixed base plates 202. Several sets of power distribution loading plates 204 can be assembled and fixed by the pair of mounting side plates 203.

[0029] Each of the two mounting side plates 203 has multiple evenly distributed mounting bolt holes. By engaging the mounting bolt holes and bolts, the power distribution loading plate 204 can be assembled and fixed at different heights.

[0030] like Figures 3 to 4 As shown, several sets of power distribution loading plates 204 are disposed on one side of a pair of assembly side plates 203, and the two ends of the several sets of power distribution loading plates 204 are bolted to the assembly side plates 203. Various electrical components can be assembled and fixed through the power distribution loading plates 204.

[0031] like Figures 3 to 4 As shown, a pair of buffer-type fixing components are respectively assembled on the upper and lower sides of the power distribution frame 201 to provide insulation protection, buffer fixing limit and auxiliary heat dissipation for the power distribution frame 201.

[0032] like Figures 5 to 9 As shown, the buffer-type fixing assembly includes a clamping fixing plate 205, an insulating buffer pad 206, multiple sets of buffer springs 207, an exhaust plate 208, and multiple damping exhaust holes 209. The clamping fixing plate 205 is sleeved on the outside of the distribution frame 201. The distribution frame 201 is clamped, fixed, and limited by the cooperation of a pair of clamping fixing plates 205. The insulating buffer pad 206 is disposed between the clamping fixing plate 205 and the distribution frame 201.

[0033] It is worth noting that the insulating buffer pad 206 has an L-shaped cross-section. The insulating buffer pad 206 serves to buffer, limit, and provide insulation protection for the distribution frame 201.

[0034] like Figures 5 to 9As shown, multiple sets of buffer springs 207 are fixedly installed inside the insulating buffer pad 206. The insulating buffer pad 206 can be supported and reset by the contraction and reset of the multiple sets of buffer springs 207. The exhaust plate 208 is connected to the insulating buffer pad 206, so that the internal air of the insulating buffer pad 206 can be discharged along the exhaust plate 208 when it contracts.

[0035] like Figures 5 to 9 As shown, multiple damping vent holes 209 are evenly distributed on the side of the clamping plate 205 close to the distribution frame 201. They are used to discharge the air discharged by the vent plate 208.

[0036] Preferably, the diameter of one end of the plurality of damping vent holes 209 located within the clamping and fixing plate 205 is larger than the diameter of the other end, and all the plurality of damping vent holes 209 are connected to the vent plate 208. This causes the plurality of damping vent holes 209 to exhibit a state where the exhaust velocity is greater than the intake velocity under the action of the diameter, thereby causing the insulating buffer pad 206 to be in a state of slow recovery expansion after contraction and exhaust, which plays a role in buffering and shock absorption for the distribution frame 201.

[0037] like Figures 7 to 13 As shown, the anti-collision diversion mechanism 3 is fixedly installed on the outside of the power distribution rack 201 to provide anti-collision protection and diversion heat dissipation protection for the power distribution rack 201. The anti-collision diversion mechanism 3 includes a shielding protection component and an anti-collision diversion protection component. The shielding protection component is fixedly installed on the top of the cabinet 1.

[0038] like Figures 7 to 8 As shown, the shielding and protection assembly includes a top cabinet 301, a pair of airflow guide pipes 302, a pair of dust filters 303, multiple sets of cooling fans 304, and airflow guide cones 305. The top cabinet 301 is fixedly installed on the top of the cabinet 1. The top cabinet 301 provides shielding and protection for the top of the cabinet 1. The pair of airflow guide pipes 302 are symmetrically arranged on both sides of the top cabinet 301, and the pair of dust filters 303 are fixedly installed on the side of the top cabinet 301 closest to the airflow guide pipes 302. The dust filters 303 provide dust protection for the airflow guide pipes 302.

[0039] like Figures 10 to 13 As shown, multiple cooling fans 304 are fixedly connected to one end of a pair of guide pipes 302 located inside the top cabinet 301. By controlling the operation of the multiple cooling fans 304, outside air can be transported to the top cabinet 301 along the guide cone 305, thereby accelerating the air circulation speed inside the cabinet 1 and ensuring the heat dissipation effect of the pre-assembled electrical cabinet.

[0040] like Figure 7 As shown, the guide cone 305 is fixedly installed at the center of the top cabinet 301, and the guide cone 305 is inverted cone shape. The guide cone 305 plays a role in limiting and guiding the airflow inside the top cabinet 301.

[0041] The anti-collision and current diversion protection component is fixedly installed between the power distribution rack 201 and the cabinet 1 to provide anti-collision buffering and current diversion and heat dissipation protection for the power distribution rack 201.

[0042] like Figures 10 to 13 As shown, the anti-collision and airflow guiding protection assembly includes an inner cabinet 306, multiple sets of buffer baffles 307, multiple sets of dust filter media 308, multiple sets of heat-conducting media 309, and an electric louvered air inlet assembly. The inner cabinet 306 is fixedly sleeved on the outside of the electrical distribution frame 201. The inner cabinet 306 serves to assemble and fix the mounting plate 205. The multiple sets of buffer baffles 307 are fixedly set on the outside of the inner cabinet 306, and the multiple sets of buffer baffles 307 are reciprocated by bending to form filter media cavities close to the inner cabinet 306 and heat-conducting media cavities close to the cabinet 1.

[0043] like Figures 10 to 13 As shown, multiple sets of dust filter media 308 and heat-conducting media 309 are respectively filled in the filter media cavity and the heat-conducting media cavity. The inner cabinet 306 has multiple evenly distributed guide holes in the part that contacts the filter media cavity. Multiple ventilation holes are opened on the buffer baffle 307. Multiple filter media cavities and heat-conducting media cavities are connected through the ventilation holes. The electric louver air inlet assembly is installed in the clamping and fixing plate 205 located above, and is used to control the ventilation status of the clamping and fixing plate 205.

[0044] like Figures 7 to 9 As shown, the return flow support mechanism 4 is fixedly installed below the cabinet 1. The return flow support mechanism 4 includes a base box 401, an exhaust fan 402, a return flow filter 403, a pair of mesh frames 404, multiple porous dust filter balls 405, an exhaust pipe 406, and an anti-clogging filter 407. It is used to support the bottom of the cabinet 1, guide dust flow, and assist in heat dissipation.

[0045] like Figure 1 As shown, the base box 401 is fixedly installed below the cabinet 1. The base box 401 serves to enclose, support, and limit the bottom of the cabinet 1.

[0046] like Figure 7 As shown, the exhaust fan 402 is fixedly installed between the base box 401 and the clamping plate 205. By controlling the operation of the exhaust fan 402, the air circulation inside the distribution rack 201 can be accelerated, further ensuring the ventilation and heat dissipation effect of various electrical components inside the distribution rack 201.

[0047] like Figure 7 As shown, the return filter 403 is mounted on the lower clamping plate 205, and both ends of the exhaust fan 402 and the return filter 403 are connected to the electrical distribution frame 201 and the base box 401, respectively. The anti-clogging filter 407 can provide dust protection for the exhaust fan 402.

[0048] like Figures 7 to 9As shown, a pair of mesh frames 404 are symmetrically distributed on both sides of the exhaust fan 402. The mesh frames 404 provide assembly and positioning for multiple porous dust filter balls 405. Each porous dust filter ball 405 is filled within the pair of mesh frames 404, and each porous dust filter ball 405 is filled with filter media. Through the cooperation of the porous dust filter balls 405 and the filter media, the air discharged from the bottom chamber 401 can be filtered for dust.

[0049] like Figures 7 to 9 As shown, the exhaust pipe 406 is fixedly installed on the side of the base box 401, and the anti-clogging filter 407 is fixedly installed at the end of the exhaust pipe 406 located outside the base box 401. Through the cooperation of the exhaust pipe 406 and the anti-clogging filter 407, the air filtered by dust in the base box 401 can be discharged.

[0050] It is worth noting that the top opening of the anti-clogging filter 407 is angled towards the cabinet 1. This allows the air exhausted from the anti-clogging filter 407 to circulate along the outside of the cabinet 1, thereby further improving the ventilation and heat dissipation effect of the cabinet 1 itself. In addition, the anti-clogging filter 407 allows filtered air to be exhausted from bottom to top, which not only cleans the dust filter 303 with air, but also continuously supplies filtered air to the dust filter 303, ensuring the subsequent ventilation and heat dissipation effect of the electrical distribution rack 201.

[0051] In addition, a wire-passing hole is provided on the clamping and fixing plate 205 located below, and a wire guide frame 408 is fixedly installed on one side of the base box 401. The cables in the power distribution frame 201 can be led out through the wire-passing hole and the wire guide frame 408.

[0052] An installation method for a pre-assembled electrical cabinet includes the following steps: S1. During the assembly of the pre-assembled electrical cabinet, a pair of clamping and fixing plates 205 are fixedly connected to the inner cabinet 306 so that the pair of clamping and fixing plates 205 clamp and fix the distribution frame 201. Furthermore, the vertical height and horizontal position of the distribution loading plate 204 are adjusted according to actual needs. S2. Subsequently, multiple sets of buffer baffles 307 are fixedly installed on the side of the inner cabinet 306, and multiple sets of dust filter packing 308 and heat-conducting packing 309 are filled into the filter packing cavity and the heat-conducting packing cavity respectively. Through the cooperation of the top cabinet 301 and the return flow bearing mechanism 4, the top and bottom of the cabinet 1 can be sealed and protected, thus completing the assembly process of the pre-assembled electrical cabinet. S3. In practical applications, various electrical components can be assembled and fixed by several sets of power distribution loading plates 204, and the power distribution frame 201 can be insulated and buffered by the cooperation of clamping and fixing plates 205, insulating buffer pads 206 and buffer springs 207. S4. When the distribution frame 201 is subjected to external impact, the distribution frame 201 will apply force to the insulating buffer pad 206, causing multiple sets of buffer springs 207 to be compressed under the action of external force. As a result, the insulating buffer pad 206 will shrink synchronously with the shaking of the distribution frame 201. When the insulating buffer pad 206 shrinks under the action of external force, the air inside the insulating buffer pad 206 will be discharged along the exhaust plate 208 and the damping exhaust hole 209. The shrinkage and reset of the insulating buffer pad 206 will buffer and protect the distribution frame 201 from impact. In addition, the exhaust through multiple sets of damping exhaust holes 209 will accelerate the air circulation outside the distribution frame 201, which will play an auxiliary role in heat dissipation protection for the electrical components installed inside the distribution frame 201. S5. In addition, the top cabinet 301 provides top shielding protection for the cabinet 1, and the buffer baffle 307, multiple sets of dust filter packing 308 and multiple sets of heat-conducting packing 309 provide anti-collision buffer protection for the distribution rack 201. Furthermore, by controlling the operation of multiple sets of cooling fans 304, outside air is delivered into the cabinet 1, and the electrical components in the distribution rack 201 are ventilated and cooled by supplying air into the cabinet 1. S6. In addition, the air in the top cabinet 301 will be transported laterally into the cabinet 1 after being heated or filtered by multiple sets of dust filter packing 308 and heat-conducting packing 309. At the same time, the heat dissipation stability of the pre-assembled electrical cabinet is ensured by the heat conduction effect of the buffer baffle 307 and the dust filter packing 308. S7. By controlling the operation of the exhaust fan 402, air can be drawn from the distribution rack 201, further increasing the air circulation speed within the distribution rack 201. After being filtered for dust, the air in the distribution rack 201 is discharged along the anti-clogging filter 407. The air discharged from the anti-clogging filter 407 can circulate along the outside of the cabinet 1, thereby further improving the ventilation and heat dissipation effect of the cabinet 1 itself. Furthermore, the anti-clogging filter 407 allows filtered air to be discharged from bottom to top, not only cleaning the dust filter 303 but also continuously supplying filtered air to the dust filter 303, ensuring the subsequent ventilation and heat dissipation effect of the distribution rack 201.

10. An installation method for a pre-assembled electrical cabinet as described in claim 9, characterized in that, Includes the following steps: S1. During the assembly of the pre-assembled electrical cabinet, a pair of clamping and fixing plates are fixedly connected to the inner cabinet to clamp and fix the distribution frame. The vertical height and horizontal position of the distribution loading plate can be adjusted according to actual needs. S2. Subsequently, multiple sets of buffer baffles are fixedly installed on the side of the inner cabinet, and multiple sets of dust filter packing and heat conduction packing are filled into the filter packing cavity and heat conduction packing cavity respectively. Through the cooperation of the top cabinet and the return flow bearing mechanism, the top and bottom of the cabinet can be sealed and protected, thus completing the assembly process of the pre-assembled electrical cabinet. S3. In practical applications, various electrical components can be assembled and fixed using several sets of power distribution loading plates. Furthermore, the distribution frame can be insulated and buffered through the cooperation of clamping plates, insulating buffer pads, and buffer springs. S4. When the distribution frame is subjected to external impact, the distribution frame will apply force to the insulating buffer pad, causing multiple sets of buffer springs to be compressed under the action of external force. As a result, the insulating buffer pad will shrink synchronously with the shaking of the distribution frame. When the insulating buffer pad shrinks under the action of external force, the air inside the insulating buffer pad will be discharged along the exhaust plate and damping exhaust hole. The shrinkage and reset of the insulating buffer pad will buffer and protect the distribution frame from impact. In addition, the exhaust method through multiple sets of damping exhaust holes will accelerate the air circulation on the outside of the distribution frame. S5. In addition, the top cabinet provides top protection for the cabinet, and the baffle plate, multiple sets of dust filter packing and multiple sets of heat-conducting packing provide anti-collision buffer protection for the distribution rack. Furthermore, by controlling the operation of multiple sets of cooling fans, outside air is delivered into the cabinet, and the electrical components inside the distribution rack are ventilated and cooled by supplying air into the cabinet. S6. In addition, the air inside the top cabinet will be transported laterally into the cabinet body after being heated or filtered by multiple sets of dust filter packing and heat-conducting packing. At the same time, the heat dissipation stability of the pre-assembled electrical cabinet is ensured by the heat conduction effect of the buffer baffle and dust filter packing. S7. The bottom of the cabinet is supported and limited by the return flow bearing mechanism. The air inside the cabinet is discharged through the dust filtration of the return flow bearing mechanism, so as to ventilate and dissipate heat in the cabinet and clean the dust filter with air blowing.
