Description

Technical Field

[0001] This utility model relates to the field of high-voltage switchgear technology, specifically a dustproof high-voltage switchgear. Background Technology

[0002] High-voltage switchgear refers to electrical products used in power systems for switching, control, or protection in power generation, transmission, distribution, energy conversion, and consumption. It includes several major categories such as high-voltage disconnect switches and grounding switches, high-voltage load switches, high-voltage automatic reclosers and sectionalizing devices, high-voltage operating mechanisms, high-voltage explosion-proof distribution equipment, and high-voltage switchgear. These are mainly suitable for various applications including power plants, substations, petrochemical plants, metallurgical steel rolling mills, light industry and textiles, factories and mines, residential communities, and high-rise buildings.

[0003] Currently, most high-voltage switchgear in existing technology uses dust filters at the air inlet to filter dust in the air and achieve dust prevention inside the switchgear. However, when in use, such as when the switchgear door is opened or closed, external dust can still enter through the door, preventing the dust inside the switchgear from being discharged and causing it to fall onto the internal electrical structure. Therefore, the dust prevention effect is not good. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a dustproof high-voltage switchgear, which solves the problem that in existing high-voltage switchgear, when in use, such as when the switchgear door is opened or closed, external dust can still enter through the switchgear door, thus preventing the dust inside the switchgear from being discharged and causing it to fall onto the internal electrical structure, resulting in poor dustproof performance.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a dustproof high-voltage switchgear, including a switchgear body and a cabinet door hinged to it by a hinge, a first handle is fixedly connected to the middle of the outer wall of the cabinet door, and a baffle plate is hinged to the outside of a pair of louvers of the cabinet door by a hinge, and a dustproof mechanism and an adjustment mechanism are respectively installed on the outside and inside of the switchgear body. The dustproof mechanism includes a pair of air inlet pipes connected to the side wall of the switch cabinet body. The outer wall of the air inlet of the air inlet pipe is connected to a fan by bolt thread. The air outlet of the air inlet pipe is provided with a card plate that fits against the inner wall of the switch cabinet body. The card plate has a first filter layer and a second filter layer in the card slot. The bottom end of the air inlet pipe is connected to a sewage pipe.

[0006] Preferably, the adjustment mechanism includes several connecting rods connected to a pair of clamping plates. A screw is fixedly connected to the top of the upper clamping plate. A sleeve is threadedly connected to the outer wall of the top of the screw, and the sleeve is rotatably connected to the switch cabinet body through a bearing. A second handle is fixedly connected to the outer wall of the sleeve.

[0007] Preferably, a partition is fixedly connected inside the switch cabinet body.

[0008] Preferably, a plurality of mesh plates are fixedly connected to the interior of the partition.

[0009] Preferably, the sidewall of the partition is fixedly connected to a plurality of support plates, and the front and rear outer walls of the support plates are fixedly connected to the inner wall of the switch cabinet body.

[0010] Preferably, each of the two openings at the front end of the switch cabinet body is connected to a cover plate by bolts and threads.

[0011] Beneficial effects This utility model provides a dustproof high-voltage switchgear, which has the following advantages: Open the baffle plate and start the fan to draw outside air into the air intake pipe, and then discharge it into the switch cabinet body through the air intake pipe. At the same time, the outside air will pass through the first and second filter layers in sequence for filtration, and carry the heat from the electrical equipment inside the switch cabinet body out through the louvers of the cabinet door. This achieves the initial dust prevention. During use, as the cabinet door opens and closes repeatedly, external dust will enter the switch cabinet body through the door. At this time, the baffle plate can be closed, and the second handle can be turned. The second handle drives the sleeve to rotate, causing the sleeve to move the screw upward. This screw, in conjunction with the connecting rod, can move a pair of clamping plates upward until the upper clamping plate contacts the sleeve, thus exposing the air inlet pipe. At this point, the fan can be reversed to evacuate the switch cabinet body. This allows the dust inside the switch cabinet body to be discharged through the air inlet pipe and the fan. After the evacuation is complete, the drain pipe valve can be opened to further discharge the dust in the air inlet pipe. This method provides better dust prevention. Attached Figure Description

The outer wall of the air inlet of the air inlet pipe 4 is connected to a fan 5 by bolt thread. The air outlet of the air inlet pipe 4 is provided with a card plate 6 that fits against the inner wall of the switch cabinet body 1. The card slot of the card plate 6 is fitted with a first filter layer 7 and a second filter layer 8. The bottom end of the air inlet pipe 4 is connected to a sewage pipe 9. Two louvers are machined on the cabinet door 2. A magnetically fixed baffle plate 18 is installed on the outside of the louvers to block them. The fan 5 is an SFWF-6 model or other fan that can rotate in both directions. A slot is machined inside the card plate 6 to hold the first filter layer 7 and the second filter layer 8. The first filter layer 7 is made of filter cotton, and the second filter layer 8 is a composite filter element.

[0019] In this embodiment, the adjustment mechanism is further configured such that the adjustment mechanism includes several connecting rods 10 connected to a pair of clamping plates 6, a screw 11 is fixedly connected to the top of the upper clamping plate 6, a sleeve 12 is threadedly connected to the outer wall of the top of the screw 11, and the sleeve 12 is rotatably connected to the switch cabinet body 1 through a bearing, and a second handle 13 is fixedly connected to the outer wall of the sleeve 12. Turn the second handle 13, which will drive the sleeve 12 to rotate, causing the sleeve 12 to drive the screw 11 to move upward. In this way, the screw 11, together with the connecting rod 10, can drive a pair of clamping plates 6 to move upward until the upper clamping plate 6 contacts the sleeve 12, thus exposing the air intake pipe 4.

[0020] In this embodiment, a partition 14 is further fixedly connected inside the switch cabinet body 1.

[0021] In this embodiment, a plurality of mesh plates 15 are fixedly connected to the interior of the partition 14; Gas can circulate through the mesh plate 15.

[0022] In this embodiment, the partition 14 is further configured such that a plurality of support plates 16 are fixedly connected to the side wall, and the front and rear outer walls of the support plates 16 are fixedly connected to the inner wall of the switch cabinet body 1. Electrical equipment is installed on the support plate 16.

[0023] In this embodiment, the front end of the switch cabinet body 1 is further configured such that a cover plate 17 is connected to a pair of openings by bolts and threads. After removing the cover plate 17, the first filter layer 7 and the second filter layer 8 can be replaced.

[0024] It is worth noting that all standard parts used in this utility model can be purchased from the market, and irregularly shaped parts can be customized according to the description and drawings. The specific connection methods of each part all adopt conventional methods such as bolts, rivets, and welding, which are mature technologies in the prior art. The models of electrical structure equipment involved can be selected according to the user's needs, as long as they meet the requirements of this application. In addition, the circuit connection adopts conventional connection methods in the prior art. The control, current detection, position feedback, predicted voltage synchronization, and parameter adjustment of the electrical equipment are all existing technologies and will not be described in detail here. All contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0025] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.

[0026] Example: When this device is needed, the components can be assembled according to the diagram according to the assembly process. Ensure that the bolts are tightened and the welding is firm. Then connect the circuit and control device. After checking that all interfaces are correct, power on and test to ensure that the current detection, position feedback and other functions are normal. Then install the control device in the appropriate position. After that, open the baffle plate 18 and start the fan 5 so that the fan 5 draws the outside air into the air inlet pipe 4 and then discharges it into the switch cabinet body 1 through the air inlet pipe 4. At the same time, the outside air will pass through the first filter layer 7 and the second filter layer 8 in sequence for filtration, and carry the heat from the electrical equipment inside the switch cabinet body 1 and discharge it through the louvers of the cabinet door 2. This achieves the initial dust prevention. During use, as the cabinet door 2 opens and closes repeatedly, external dust will enter the switch cabinet body 1 through the cabinet door 2. At this time, the baffle plate 18 can be closed, and the second handle 13 can be turned. The second handle 13 will drive the sleeve 12 to rotate, causing the sleeve 12 to drive the screw 11 to move upward. In this way, the screw 11, together with the connecting rod 10, can drive a pair of clamping plates 6 to move upward until the upper clamping plate 6 contacts the sleeve 12, thus exposing the air inlet pipe 4. At this time, the fan 5 can be reversed, and the fan 5 can evacuate the inside of the switch cabinet body 1. In this way, the dust inside the switch cabinet body 1 can be discharged through the air inlet pipe 4 and the fan 5. After the evacuation is finished, the valve of the drain pipe 9 can be opened to further discharge the dust in the air inlet pipe 4. This will improve the dust prevention effect.
