Description

Technical Field

[0001] The utility model relates to the field of power equipment monitoring, in particular to power equipment monitoring equipment based on power system wide area control. Background Art

[0002] Power equipment is usually installed in a power cabinet, while some power cabinets are usually located outdoors, and some power cabinets are close to the desert. Being close to the desert will cause the dust and sand content in the air to be extremely high. A Chinese patent with publication number CN219163953U discloses a power switch cabinet monitoring device. The patent sets a mesh plate at the fan of the power switch cabinet to prevent some dust from entering the power cabinet through the mesh plate, thereby preventing dust from affecting the gas monitoring results. However, during the operation of the power cabinet, the fan itself blows outward, so the amount of dust entering the power cabinet through the fan is relatively small, and there will be staff to inspect the power equipment in the power cabinet, which requires the staff to open the door of the power cabinet. The dust and sand content in the air close to the desert is extremely high, so a large amount of dust and sand in the outside air will enter the power cabinet, affecting the gas monitoring results;

[0003] Moreover, the proximity to the desert will result in a huge temperature difference between day and night. The moisture content in the air at night when the temperature is lower is higher. The moisture in the air can easily enter the power cabinet through the fan, increasing the humidity inside the power cabinet. If it is not discharged in time, it will affect the operation of the power equipment in the power cabinet. Utility Model Content

[0004] In order to overcome the disadvantage that when the staff repair the power equipment in the power cabinet, the staff needs to open the door of the power cabinet, so a large amount of dust and sand in the outside air will enter the power cabinet and affect the gas monitoring results, the utility model provides a power equipment monitoring device based on wide area control of the power system.

[0005] The technical solution is: an electric power equipment monitoring device based on wide-area control of an electric power system, comprising an electric power cabinet, a cabinet door, a cooling fan and a filter; the electric power cabinet is rotatably connected to a plurality of cabinet doors; the electric power cabinet is fixedly connected to a plurality of cooling fans; the electric power cabinet is slidably connected to a filter, and the filter is provided with a matching groove, and the filter is provided with a matching hole; it also comprises a sliding block and a limiting block; the left and right sides of the electric power cabinet are both slidably connected to a plurality of sliding blocks; the left and right sides of the electric power cabinet are both slidably connected to a plurality of limiting blocks, and all limiting blocks are located above adjacent sliding blocks.

[0006] Furthermore, it also includes a fixing block, and the power cabinet is fixedly connected with a plurality of fixing blocks, and the fixing blocks are fixedly connected with the corresponding filter screens.

[0007] Furthermore, the filter screen has a certain elasticity.

[0008] Furthermore, the sliding block is arranged in an I-shape.

[0009] Furthermore, a rubber layer is provided at the edges of all cabinet doors.

[0010] Furthermore, it also includes a fixed plate and a dehumidification channel; the power cabinet is fixedly connected to the fixed plate; the fixed plate is fixedly connected to a plurality of dehumidification channels, and all the dehumidification channels are provided with water-absorbing materials such as activated carbon.

[0011] The beneficial effects are as follows: the utility model can suck out the dust and sand in the power cabinet through the cooling fan, and the staff can pull the filter screen so that a certain gap is formed between the edge of the filter screen and the power cabinet, so that the dust and sand in the power cabinet can be discharged from the gap between the edge of the filter screen and the power cabinet, thereby preventing a large amount of dust and sand in the air from entering the power cabinet and affecting the monitoring results of the gas monitor;

[0012] The utility model reverses the cooling fan at night so that the cooling fan blows air into the power cabinet, thereby sucking cold air in the night air into the power cabinet, thereby efficiently dissipating the heat in the power cabinet, and filtering out dust and sand through the filter screen to prevent the cooling fan from reversing and sucking dust and sand into the power cabinet.

[0020] The technical solution of the utility model is further described below in conjunction with the accompanying drawings.

[0021] Example

[0022] A power equipment monitoring device based on power system wide area control, such as Figure 1-6 As shown, it includes a power cabinet 1, a cabinet door 2, a cooling fan 3 and a filter 4; the power cabinet 1 is rotatably connected to two cabinet doors 2; the power cabinet 1 is bolted to four cooling fans 3; the power cabinet 1 is slidably connected to a filter 4, and the filter 4 is provided with a matching groove 4a, and the filter 4 is provided with a matching hole 4b;

[0023] It also includes a sliding block 5 and a limit block 6; the left and right sides of the power cabinet 1 are slidably connected with four rectangularly distributed sliding blocks 5; the left and right sides of the power cabinet 1 are slidably connected with four rectangularly distributed limit blocks 6, and all the limit blocks 6 are located above the adjacent sliding blocks 5, and the filter 4 is limited by the limit blocks 6.

[0024] The power cabinet 1 further includes a fixing block 7 . The two fixing blocks 7 are fixedly connected to the power cabinet 1 , and the fixing blocks 7 are fixedly connected to the corresponding filter screens 4 .

[0025] The filter screen 4 has a certain elasticity, so that the filter screen 4 can be stretched into a cone shape after being moved, so as to facilitate the discharge of dust and sand in the power cabinet 1.

[0026] The sliding block 5 is arranged in an I-shape.

[0027] The edges of all the cabinet doors 2 are provided with a rubber layer so that air cannot enter or exit through the gaps of the cabinet doors 2 .

[0028] It also includes a fixed plate 101 and a dehumidification channel 102; the power cabinet 1 is fixedly connected to the fixed plate 101; the fixed plate 101 is fixedly connected to six dehumidification channels 102, and all the dehumidification channels 102 are provided with water-absorbing materials such as activated carbon, and the moisture in the air entering the power cabinet 1 is absorbed through the dehumidification channels 102.

[0029] The working steps of the above embodiment are: first, the staff installs the utility model at the required position, then installs the power equipment to be installed in the power cabinet 1, and connects the wires to complete the installation of the power equipment, then monitors the gas composition in the power cabinet 1 through the gas monitor, so as to monitor whether there is a discharge phenomenon in the power equipment in the power cabinet 1, and monitors the temperature and humidity in the power cabinet 1 through the temperature and humidity monitor to prevent the temperature or humidity of the power cabinet 1 from being too high and affecting the operation of the power equipment; when dissipating heat, the heat dissipation fan 3 is driven to rotate to extract the hot air inside the power cabinet 1 out of the power cabinet 1, so as to achieve the effect of preventing the internal temperature of the power cabinet 1 from being too high;

[0030] It should be noted that, since the power cabinet 1 is set up in some areas with relatively strong sandstorms, the filter 4 is used to intercept dust and sand outside the power cabinet 1 to prevent dust and sand from entering the power cabinet 1 through the cooling fan 3, so as to prevent dust and sand from entering the power cabinet 1 and affecting the monitoring results of the gas monitor;

[0031] Since there is more moisture in the air at night, more moisture will enter the power cabinet 1 from the dehumidification channel 102 during the heat dissipation process of the cooling fan 3, so that the humidity in the power cabinet 1 increases. Therefore, during the rotation of the cooling fan 3, since the edge of the cabinet door 2 is provided with a rubber layer, the air cannot enter or exit from the gap of the cabinet door 2, so the air will enter the power cabinet 1 from the dehumidification channel 102. When the air passes through the dehumidification channel 102, the water-absorbing material such as activated carbon in the dehumidification channel 102 can absorb the moisture in the air, so that during the rotation of the cooling fan 3, the humidity in the power cabinet 1 can be reduced;

[0032] During the maintenance of the power cabinet 1, the staff needs to open the cabinet door 2. At this time, dust and sand in the air will enter the power cabinet 1, affecting the monitoring results of the gas monitor. Therefore, after the staff completes the maintenance, the staff can pull up the filter 4, so that the filter 4 and all the parts connected to it move upward, and the sliding block 5 slides in the matching groove 4a, and makes the matching hole 4b move to the top of the limit block 6. The limit block 6 and the matching hole 4b no longer match and cannot produce a limiting effect. Then the staff pulls the filter 4 away from the power cabinet 1. During this process, the sliding block 5 moves outside the power cabinet 1, and after moving a certain distance, it pulls the filter 4 downward, inserts the matching hole 4b into another convex point of the limit block 6, and limits the filter 4 again. Since the fixing block 7 is fixed to the power cabinet 1 , so the fixing block 7 cannot move away from the power cabinet 1, so that the filter 4 will be slightly deformed, from the initial straight shape to a cone shape, and a certain gap will be formed between the edge of the filter 4 and the power cabinet 1, so that during the rotation of the cooling fan 3, the cooling fan 3 will suck out the dust and sand in the power cabinet 1, and the dust and sand in the power cabinet 1 can be discharged from the gap between the edge of the filter 4 and the power cabinet 1, and the filter 4 has a certain inclination, so the dust and sand will be guided to the outside of the filter 4, which is conducive to the discharge of dust and sand, thereby reducing the content of dust and sand in the power cabinet 1, avoiding affecting the monitoring results of the gas monitor, and then after a period of time, the cooling fan 3 discharges the dust and sand in the power cabinet 1, and then the staff will reset the filter 4 again.

[0033] Those skilled in the art should understand that the above embodiments do not limit the present invention in any form, and any technical solutions obtained by equivalent replacement or equivalent transformation shall fall within the protection scope of the present invention.
