Description

Technical Field

[0001] The invention relates to the field of power distribution cabinets, in particular to a high and low voltage power distribution cabinet based on power environment harmonic pollution monitoring. Background Art

[0002] With the rapid development of electronic appliances, computers and power electronics technology, a large number of nonlinear loads have been added to the power grid. These loads cause great interference to the power grid and produce distortion. The power grid is no longer a single 50Hz sinusoidal waveform, but also includes a series of sinusoidal components with frequencies that are integer multiples of the fundamental wave. These components are called harmonics. When the harmonic components in the power grid exceed a certain level, it will cause harmonic pollution and serious damage. As the harmonic pollution of the power grid becomes increasingly serious, the monitoring and comprehensive management of harmonics have received great attention. The existing high and low voltage distribution cabinets mainly monitor and process harmonics effectively by installing harmonic pollution monitors in the cabinets; For example, the prior art application number CN201920528357.5 discloses a high and low voltage distribution cabinet based on harmonic pollution monitoring of the power consumption environment, including a cabinet body, an air outlet hood and a sliding rod, wherein two ends of one side of the interior of the cabinet body are provided with sliding grooves, a pulley is slid inside the sliding groove, a sliding rod is fixedly installed in the middle of the pulley, a slider is fixedly installed in the middle of the sliding rod, a reciprocating screw is inserted and installed inside the slider, and the bottom end of the reciprocating screw is rotatably installed on the output end of the second motor, an air outlet hood is provided on the middle surface of the sliding rod, and both sides of the rear surface of the air outlet hood are fixedly installed on the surface of the sliding rod through fixing blocks, the rear end of the air outlet hood is connected to the output end of the first motor through a transmission pipe, and an air inlet is provided at the input end of the first motor; The above scheme is known through actual usage. It is known that it mainly uses the operation of fan blades to blow the residual dust in the cabinet to float, and then uses the axial flow fan to discharge the hot air containing dust in the cabinet, so as to achieve the purpose of dust removal and heat dissipation. However, it is found in use that the single use of fan blades to blow air into the cabinet is likely to produce many dead corners, resulting in the dust remaining in the cabinet cannot be blown up. At the same time, the dust-containing gas discharged by the axial flow fan will exist around the cabinet for a short time. When the fan blades continue to rotate, it is easy to be sucked into the cabinet again, causing the cabinet to be covered with dust again, and then resulting in reduced dust removal and heat dissipation effects. For this reason, we have improved the above scheme according to actual usage. Summary of the invention

[0003] The main purpose of the present invention is to provide a high and low voltage distribution cabinet based on harmonic pollution monitoring of the power consumption environment, which can effectively solve the problem that the background technology only uses fan blades to blow air inside the cabinet, which easily produces many dead corners, resulting in the dust remaining in the cabinet being unable to be blown away. At the same time, the dust-containing gas discharged by the axial fan will exist around the cabinet for a short time, and when the fan blades continue to rotate, it is easy to be sucked into the cabinet again, causing the cabinet to be covered with dust again, thereby reducing the dust removal and heat dissipation effects.

The inner and outer walls of the cabinet 1 are respectively fixed by bolts with a harmonic pollution monitor 3 and a plc control board 11, and the top of the cabinet 1 is fixed by bolts with an alarm light 4; the inner walls of both sides of the cabinet 1 are connected by bolts with a duct assembly 6, and the output end of the No. 2 axial flow fan 7 is connected by bolts with a collection assembly 8; the harmonic pollution monitor 3, the alarm light 4, the No. 2 axial flow fan 7, and the No. 1 axial flow fan 9 are all connected to the plc control board 11 through wires, and the operation and shutdown of the above electrical components can be controlled by the plc control board 11. The air duct assembly 6 includes a hose 601, an air outlet No. 1 604, an air outlet No. 2 605, and a hollow tube 602. One end of the hose 601 is fixed to the output end of the No. 1 axial flow fan 9 by bolts and are interconnected. The other end of the hose 601 is integrally connected to the hollow tube 602. The inner side of the hollow tube 602 is integrally connected with the air outlet No. 1 604 and the air outlet No. 2 605. A tube cover is integrally provided on the inner side of the No. 1 axial flow fan 9. The hose 601 is fixedly connected and connected to the tube cover by bolts, so that the wind force of the No. 1 axial flow fan 9 will be delivered to the hose 601. The collecting assembly 8 comprises a conveying pipe 801, an outer box 802, an inner box 803, a conical tube 804 and a gap 812. One end of the conveying pipe 801 is fixedly connected to the output end of the No. 2 axial flow fan 7 by bolts and the two are interconnected. The output end of the No. 2 axial flow fan 7 is also integrally provided with a tube cover, and the tube cover in the output end of the No. 2 axial flow fan 7 is fixedly connected to the conveying pipe 801 by bolts and is interconnected; the other end of the conveying pipe 801 is integrally provided with an outer box 802, and the inner box 803 is movably provided in the outer box 802. The conical tube 804 is fixedly provided on the inner wall of the inner box 803 by rivets, and a gap 812 is provided on the tube wall of the conical tube 804. One end opening of the conical tube 804 corresponds to the port of the conveying pipe 801. A wire inlet hole 10 is provided on one side of the cabinet 1, and a mounting frame 16 is integrally provided on one side of the cabinet 1. The lower surface of the mounting frame 16 is fixedly connected to the outer box 802 by bolts. An outlet 811 is disposed at one end of the conical tube 804 , and the slit 812 extends to the end of the outlet 811 .

[0027] Through the above scheme, the harmonic pollution monitor 3 is used to monitor the harmonic pollution in the cabinet 1. If there is harmonic pollution, the alarm light 4 will flash to remind the staff to respond in time. When it is necessary to clean the dust remaining inside the cabinet 1, the PLC control panel 11 can be used to start the No. 1 axial flow fan 9 to rotate and generate accelerated airflow. The airflow will then be divided into two parts and respectively transported to the two hoses 601 in the air duct assembly 6. Then the airflow in the two hoses 601 will reach the hollow tube 602 and be ejected from the No. 1 air outlet 604 and the No. 2 air outlet 605. After the dust is blown up, when the No. 2 axial flow fan 7 is turned on, the dust inside the cabinet 1 will be blown away. The dusty air is sucked into the delivery pipe 801 in the collection assembly 8, and then passes through the conical cylinder 804 to reach the inner box 803 to be collected; when the second axial flow fan 7 is running, the outlet 811 at one end of the conical cylinder 804 will be blown open and expanded by the airflow, so that the dust can enter the inner box 803 for collection. When the second axial flow fan 7 is turned off, the outlet 811 of the conical cylinder 804 will close and block the dust in the inner box 803 to prevent the dust from overflowing into the cabinet 1. It should be noted that the inner box 803 is also provided with a circular hole at the place opposite to the delivery pipe 801, and the edge of the circular hole is fixedly connected to the conical cylinder 804 by rivets. The conical cylinder 804 is made of textile cloth and has plasticity. When the second axial flow fan 7 is started and the airflow is blown into the conical tube 804, the outlet 811 will expand and the gap 812 will become larger. On the contrary, when there is no airflow blowing into the conical tube 804, the outlet 811 will close and the gap 812 will become smaller.

[0028] refer to Figure 2 and Fig. 9 In the present application, the input end of the No. 1 axial flow fan 9 is integrally connected with a mounting frame 12, a filter plate 13 is integrally provided on the outside of the mounting frame 12, and a hygroscopic cotton 14 is detachably provided inside the mounting frame 12. The inner wall of the mounting frame 12 is slidably connected to the hygroscopic cotton 14, and a handle 15 is integrally provided on the upper surface of the hygroscopic cotton 14. Through the above scheme, when the No. 1 axial flow fan 9 rotates, the outside air will pass through the hygroscopic cotton 14 to absorb moisture to achieve the effect of dehumidifying the air, and the internal parts of the cabinet 1 are moisture-proof. At the same time, the hygroscopic cotton 14 can also further filter the dust in the air, and further prevent the dust in the external air from entering the cabinet 1 again. A hard frame can be provided on the outside of the hygroscopic cotton 14, and the inner wall of the frame is bonded to the hygroscopic cotton 14 by glue. When replacing the hygroscopic cotton 14, the hygroscopic cotton 14 is moved up and taken out by pulling the handle 15. The raw material of the hygroscopic cotton 14 is a blend of polyester fiber and viscose fiber. The filter plate 13 is provided with a plurality of circular through holes, which can filter larger dust particles.

[0029] refer to Figure 5 and Figure 7 , Figure 8In the present application, a slope No. 1 603 is provided on one side of the hollow tube 602, and an air outlet No. 1 604 is integrally connected to the inner side of the slope No. 1 603, and the air outlet No. 2 605 is arranged at an angle. A glass plate is fixedly mounted on the outer side of the outer box 802 by bolts, and a slide rail 813 is integrally arranged on the bottom wall of the outer box 802. A slide groove 810 is provided on the bottom wall of the inner box 803, and the inner wall of the slide groove 810 is slidably connected to the outer wall of the slide rail 813, and the inner box 803 slides on the slide rail 813 by pulling. An upper cavity 805 and a lower cavity 806 are provided in the inner box 803, and a through hole 808 is provided in the partition between the lower cavity 806 and the upper cavity 805. The bottom wall of the upper cavity 805 is provided with a second slope 807, the low slope of the second slope 807 is connected to the through hole 808, and the bottom wall of the upper cavity 805 is also provided with a recessed portion 809. Through the above scheme, dust will fall on the surface of the second slope 807 after entering the inner box 803 from the conical cylinder 804, and the second slope 807 can accelerate the speed of dust falling from the through hole 808 to the lower cavity 806. The surface of the second slope 807 can be mirror-finished to reduce the resistance of dust falling. After the dust is collected in the inner box 803, the dust can be regularly transferred. First, the bolts on the glass plate are screwed to disassemble the glass plate, and then the recessed portion 809 can be pinched by fingers to pull out the inner box 803 to pour out the dust inside. The recessed portion 809 can be a groove of various shapes.

[0030] Working principle of high and low voltage distribution cabinet based on power environment harmonic pollution monitoring: First, the harmonic pollution monitor 3 is used to monitor the harmonic pollution in the cabinet 1. If there is harmonic pollution, the alarm light 4 will flash to remind the staff to respond in time. When it is necessary to clean the residual dust inside the cabinet 1, the PLC control panel 11 can be used to start the No. 1 axial flow fan 9 to rotate and generate accelerated airflow. The airflow will then be divided into two parts and transported to the two hoses 601 in the air duct assembly 6 respectively. Then the airflow in the two hoses 601 will reach the hollow tube 602 and be ejected from several No. 1 air outlets 604 and No. 2 air outlets 605. Because the distribution positions of the No. 1 air outlet 604 and the No. 2 air outlet 605 are different, and the inclination angles of the No. 1 air outlet 604 and the No. 2 air outlet 605 are different, the ejected airflow will blow the dust in multiple areas of the cabinet 1, and reduce the dead corners in the dust removal, so that it is easier to quickly blow up the dust in the cabinet 1; After the dust is blown up, when the No. 2 axial flow fan 7 is turned on, the air containing dust in the cabinet 1 will be sucked into the conveying pipe 801 in the collecting assembly 8, and then the air will be collected in the inner box 803 through the conical cylinder 804; when the No. 2 axial flow fan 7 is running, the outlet 811 at one end of the conical cylinder 804 will be blown open and expanded by the airflow, so that the dust can enter the inner box 803 for collection. When the No. 2 axial flow fan 7 is turned off, the outlet 811 of the conical cylinder 804 will be closed, and the dust in the inner box 803 will be blocked to prevent the dust from overflowing into the cabinet 1, thereby preventing the dust from floating around the cabinet 1 and being sucked into the cabinet 1 again. At the same time, when the No. 1 axial flow fan 9 rotates, the outside air will pass through the hygroscopic cotton 14 to absorb moisture to achieve the effect of dehumidifying the air, while preventing moisture from the internal parts of the cabinet 1. At the same time, the hygroscopic cotton 14 can further filter the dust in the air, further preventing the dust in the outside air from entering the cabinet 1 again.

It should be understood that the present invention is not limited to the form disclosed herein, and should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be modified within the scope of the concept described herein through the above teachings or the technology or knowledge of the relevant field.
