Technical Field

[0001] The invention relates to the technical field of electrical equipment, in particular to a high and low voltage complete set of electrical equipment with a long service life. Background Art

[0002] High and low voltage electrical equipment will generate a lot of heat during operation. If the heat is not ventilated and dissipated in time, the electronic components inside the electrical equipment will accelerate oxidation and corrosion damage in a high temperature environment, which will greatly reduce the service life of the electronic components, thus seriously affecting the stable operation of the high and low voltage electrical equipment.

[0003] A high and low voltage complete set of electrical equipment is provided in the related art. When the high and low voltage complete set of electrical equipment is in operation, the fan is generally operated to filter the natural wind from the outside through the filter and then introduced into the interior of the electrical equipment.

DETAILED DESCRIPTION

[0025] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0026] Example

[0027] See also Figure 1 and Figure 2 , a high and low voltage complete electrical equipment with a long service life is provided in an embodiment of the present invention, and the high and low voltage complete electrical equipment with a long service life comprises:

[0028] The equipment body 1, the front and rear sides of the upper end of the equipment body 1 are respectively provided with an air intake filter 2 and an exhaust filter 3, the air intake filter 2 is used to filter and intercept the incoming air for the first time when the equipment body 1 is running and inhales the outside natural air for cooling; and the installed exhaust filter 3 can be used to smoothly discharge the air after heat exchange when the equipment body 1 is running, and at the same time, when the equipment body 1 stops working, it can filter and isolate the dust in the outside natural air to prevent the dust in the natural air from entering the equipment body 1; the lower end of the equipment body 1 is surrounded by cushion blocks 5, and the cushion blocks 5 arranged around the lower end of the equipment body 1 are used to stably support the entire high and low voltage complete set of electrical equipment with a long service life;

[0029] The equipment body 1 is provided with a dust removal box 7 and a cooling box 20. The dust removal box 7 is L-shaped, and the interior of the dust removal box 7 is divided into a settling chamber 8, a dust removal chamber 12 and a temporary storage chamber 18 in sequence by a partition. The settling chamber 8 is used to perform settling and dust removal on the air entering the equipment body 1. The dust removal chamber 12 is used to perform ionization and dust removal on the air passing through the settling chamber 8. The lower ends of the settling chamber 8 and the dust removal chamber 12 are both connected to a dust collecting hopper 22. The connected dust collecting hopper 22 is used to discharge the dust collected in the air entering the equipment body 1 in a centralized manner at a later stage. The temporary storage chamber 18 is connected to a cooling box 20 at the lower end, and a nitrogen pump 21 is installed inside the cooling box 20. The operation of the nitrogen pump 21 can introduce low-temperature nitrogen into the clean air entering the temporary storage chamber 18, so that the low-temperature nitrogen is mixed with the clean air and then cooled and transported to the inside of the equipment body 1, thereby realizing rapid cooling and cooling of the inside of the running equipment body 1.

[0030] An operating door 4 is movably installed at the position where the dust removal box 7 is set on one side of the equipment body 1. The movably installed operating door 4 is easy to open and is used to discharge the dust collected in the dust hopper 22 and to remove the electronic components running in the cooling box 20 in time for repair when they are damaged;

[0031] In the embodiment of the present invention, when the high and low voltage complete electrical equipment with a long service life is used, that is, the electronic components inside the equipment body 1 are powered on and operate normally, a large amount of heat will be generated inside the equipment body 1; at this time, the natural air from the outside is filtered through the provided air intake filter 2 and then introduced into the dust removal box 7;

[0032] Inside the dust removal box 7, the introduced air is subjected to dust settling through the settling chamber 8; the settled air enters the dust removal chamber 12, where it is subjected to ionization dust removal, and finally the dust-removed air enters the temporary storage chamber 18, where it is temporarily stored and then transported to the inside of the equipment body 1 to exchange heat with the hot air to cool the inside of the equipment body 1 and then discharged; sometimes, in order to quickly cool the inside of the equipment body 1, low-temperature nitrogen can be transported to the inside of the temporary storage chamber 18 through the cooling box 20 to mix with the air entering the temporary storage chamber 18 to become cold air and transported to the inside of the equipment body 1, thereby accelerating the cooling of the inside of the equipment body 1;

[0033] See also Figure 2 In one embodiment of the present invention, a guide pipe 6, a lower baffle 9 and an upper baffle 10 are sequentially arranged inside the settling chamber 8, the guide pipe 6 is L-shaped, and the outlet position of the lower end of the guide pipe 6 is directly opposite to the inner wall of the bottom end of the settling chamber 8; the lower baffle 9 and the upper baffle 10 are distributed from bottom to top inside the dust removal box 7, and a settling cavity is formed between the adjacent lower baffles 9 and the upper baffles 10, and the formed settling cavity is U-shaped; at the same time, a first exhaust hole 11 is also provided on one side of the upper end of the settling chamber 8, and the first exhaust hole 11 is connected to the inside of the dust removal chamber 12;

[0034] When the air filtered by the air intake filter 2 enters the sedimentation chamber 8, it first flows through the guide pipe 6 to the bottom of the sedimentation chamber 8 and then flows along the U-shaped sedimentation cavity. During the circulation process, the dust is settled due to the difference in specific gravity between the dust and the gas. Finally, after the dust is settled, it enters the dust removal chamber 12 through the first exhaust hole 11 to perform the next step of ionization dust removal.

[0035] See also Figure 2 and Figure 4 In one embodiment of the present invention, an ionizer 13 and an electrode plate are sequentially installed in the front and back of the dust removal chamber 12. The electrode plate is divided into a dust suction negative electrode plate 15 and a dust suction positive electrode plate 16. The dust suction negative electrode plate 15 and the dust suction positive electrode plate 16 are staggered, and an ionization interval is formed between the adjacent dust suction negative electrode plates 15 and the dust suction positive electrode plates 16. At the same time, a rectifier booster 14 is installed on one side of the dust removal chamber 12. A second exhaust hole 17 is opened at the upper end of the dust removal chamber 12, and the second exhaust hole 17 is connected to the interior of the temporary storage chamber 18.

[0036] In the embodiment of the present invention, when air enters the dust removal chamber 12, the rated current is connected to the rectifier booster 14, and the rated current flows through the rectifier booster 14 and becomes high-voltage direct current for output;

[0037] After the ionizer 13 is connected to high-voltage direct current, the dust in the incoming air is electrolyzed to charge the dust particles. When the charged dust flows with the air to the ionization interval formed between the adjacent dust collecting positive plates 16 and 15, since the dust collecting positive plate 16 and the dust collecting negative plate 15 are both energized, an electromagnetic field effect can be generated, and the charged dust can be effectively adsorbed on the surface of the dust collecting positive plate 16 and the dust collecting negative plate 15. After the power supply is stopped, the dust adsorbed on the surface of the dust collecting negative plate 15 or the dust on the surface of the dust collecting positive plate 16 falls down by its own gravity and falls into the dust collecting hopper 22 for centralized collection.

[0038] The ionized air is transported to the interior of the temporary storage chamber 18 through the second exhaust hole 17;

[0039] See also Figure 2 , Figure 3 and Figure 4In one embodiment of the present invention, a fan 19 is provided at the upper end of the inner wall of the temporary storage chamber 18, and the fan 19 is used to transport and discharge the purified air, and the hot air generated by the operation of the electronic device inside the equipment body 1 is exchanged with the hot air and then discharged; a cold air hole 23 is opened at the upper end of the inner wall of the cooling box 20, and one end of the cold air hole 23 is connected to the interior of the temporary storage chamber 18 through a pipeline; a baffle 24 is movably installed at the position where the cold air hole 23 is opened inside the cooling box 20, and one side of the baffle 24 is connected to the drive assembly, and the drive assembly is installed inside the cooling box 20; at the same time, a temperature sensor 29 is also provided inside the cooling box 20, and the temperature sensor 29 is used to monitor the temperature inside the equipment body 1 in real time;

[0040] In the embodiment of the present invention, when the temperature sensor 29 detects that the operating temperature inside the device body 1 is within the normal temperature range, the baffle 24 is driven by the driving component to rotate, so that the upper end of the baffle 24 closes the position of the cold air hole 23; at this time, the purified and dust-removed air is transported to the inside of the device body 1 through the running fan 19 in the temporary storage chamber 18;

[0041] If the temperature sensor 29 detects that the temperature inside the equipment body 1 during operation exceeds the temperature range during normal operation, the drive component and the nitrogen pump 21 are immediately controlled to operate, and the drive component outputs kinetic energy to drive the baffle 24 to rotate and open the cold air hole 23; the operating nitrogen pump 21 generates low-temperature nitrogen inside the cooling box 20, and the generated low-temperature nitrogen is transported to the temporary storage room 18, mixed with the dust-removed and purified air, and then transported to the equipment body 1 to participate in the heat exchange operation after cooling the air, which can accelerate the cooling efficiency inside the equipment body 1;

[0042] See also Figure 3 and Figure 4 Specifically, the driving assembly includes a rotating shaft 27 and a motor 25. Both ends of the rotating shaft 27 are rotatably mounted on the inner wall of the cooling box 20. A baffle 24 is mounted on the portion of the rotating shaft 27 near the cold air hole 23. A side bevel gear 28 is also provided on the rotating shaft 27. A main bevel gear 26 is provided at the output end of the motor 25. The outer side of the main bevel gear 26 is meshed with the outer side of the side bevel gear 28.

[0043] In the embodiment of the present invention, when the baffle 24 is driven to rotate by the driving assembly to close and open the cooling hole 23, the motor 25 is started, and the motor 25 runs to output kinetic energy to drive the main bevel gear 26 to rotate. When the main bevel gear 26 rotates, the outer side of the main bevel gear 26 is meshed with the outer side of the side bevel gear 28. Therefore, when the main bevel gear 26 rotates, the rotating shaft 27 can be driven to rotate, thereby rotating the baffle 24 installed on the rotating shaft 27, and adjusting the baffle 24 to open and close the position of the cooling hole 23;
