Description

Technical Field

[0001] This invention relates to the field of electric field component technology, and is particularly applicable to an adjustable contactless electric field component. Background Technology

[0002] In existing technologies, electric field components generally adopt high and low voltage dual-zone simultaneous power supply, that is, the power supply system provides working voltage to the high voltage group and the low voltage group of the electric field respectively to meet the electric field strength requirements of different areas.

[0003] However, the power supply scheme has many significant drawbacks, including poor operational reliability. The low-voltage group is prone to flashover during operation due to factors such as changes in environmental humidity, dust accumulation, and aging of insulation components. Since both high-voltage and low-voltage zones are powered simultaneously, flashover of the low-voltage group will directly trigger the protection mechanism of the entire power supply system, causing the high-voltage group to be interrupted. This will lead to the entire electric field component stopping working, severely affecting the continuous operating efficiency of the equipment. This problem can cause significant production losses, especially in industrial scenarios where high operational continuity is required. The voltages of the high-voltage and low-voltage groups in the existing power supply system are usually fixed and cannot be dynamically adjusted according to actual operating conditions. This limits the adaptability and operating efficiency of the electric field component, making it difficult to meet diverse application needs.

[0004] The aforementioned problems make it difficult for existing electric field components that simultaneously supply power to both high and low voltage zones to balance cost control, reliability, and operating condition adaptability in practical applications, thus limiting their promotion and optimized application in related fields. Summary of the Invention

[0005] The purpose of this invention is to solve the above problems and provide an adjustable contactless electric field component, including a frame, a high voltage group and a low voltage group, wherein the high voltage group and the low voltage group are both connected to the frame, and the high voltage group is electrically connected to an external power source. A high-voltage inductor is installed on the high-voltage group, and a low-voltage inductor is installed on the low-voltage group. The high-voltage inductor induces discharge to the low-voltage inductor, thereby enabling the high-voltage group to supply power to the low-voltage group. The distance between the high-voltage inductor and the low-voltage inductor is adjustable.

[0006] More specifically, the distance between the high-voltage sensing element and the low-voltage sensing element is set to 5-20mm.

[0007] More specifically, the high-voltage sensing element includes a high-voltage sensing plate and a high-voltage discharge tip, and the high-voltage sensing plate is connected to the high-voltage group; The low-voltage sensing element includes a low-voltage sensing plate and a low-voltage sensing tip, and the low-voltage sensing plate is connected to the low-voltage group. The low-pressure sensing tip and the high-pressure discharge tip are positioned opposite each other, and the distance between them is adjustable.

[0008] More specifically, the high-voltage induction plate is movably mounted on the high-voltage group, and the low-voltage induction plate is movably mounted on the low-voltage group.

[0009] More specifically, high-voltage sensors are provided at both ends of the high-voltage group, and low-voltage sensors are provided at both ends of the low-voltage group.

[0010] More specifically, the high-voltage assembly includes a first high-voltage connecting rod, a second high-voltage connecting rod, a high-voltage connecting plate, several discharge components, and several high-voltage electrode plates; Several discharge elements are spaced apart, each discharge element is mounted on a first high-voltage connecting rod, and the first high-voltage connecting rod is connected to a high-voltage connecting plate; Several high-voltage electrode plates are spaced apart, and each high-voltage electrode plate is connected to a second high-voltage connecting rod, which is connected to a frame. The high-voltage connecting plate is insulated from the frame.

[0011] More specifically, a first clearance hole is provided on the frame at a position relative to the first high-voltage connecting rod, and the diameter of the first clearance hole is larger than the diameter of the first high-voltage connecting rod.

[0012] More specifically, the low-pressure group includes a first low-pressure connecting rod, a second low-pressure connecting rod, a low-pressure connecting plate, a plurality of cathode plates and a plurality of anode plates, wherein the cathode plates and anode plates are arranged alternately and at intervals. Several of the cathode plates are connected to the first low-pressure connecting rod, and the first low-pressure connecting rod is connected to the low-pressure connecting plate; Several of the anode plates are connected to a second low-pressure connecting rod, and the second low-pressure connecting rod is connected to the frame; The low-voltage connecting plate is insulated from the frame.

[0013] More specifically, a second clearance hole is provided on the frame at a position relative to the first low-pressure connecting rod, and the diameter of the second clearance hole is larger than the diameter of the first low-pressure connecting rod.

[0014] More specifically, the frame includes a first frame and a second frame, the first frame and the second frame are detachably connected, the high voltage group is connected to the first frame, and the low voltage group is connected to the second frame.

[0015] This invention mainly designs an adjustable contactless electric field component, which eliminates the need to supply power to the low-voltage group and only requires power to the high-voltage group, thus reducing costs. Since the low-voltage group indirectly obtains its working voltage through the discharge of the high-voltage group, when the low-voltage group flashes over, it will not trigger the protection mechanism of the high-voltage group power supply system, effectively avoiding the problem of partial failure due to low-voltage group flashover, which affects the purification efficiency.

The embodiments of this invention will now be described in detail with reference to the accompanying drawings.

[0019] It should be understood that the accompanying drawings are for illustrative purposes only.

[0020] An adjustable contactless electric field component, such as Figures 1-5 As shown, it includes a frame 1, a high-voltage group 2, and a low-voltage group 3, both of which are connected to the frame 1.

[0021] The frame 1 includes a first frame and a second frame, which are detachably connected. The high-voltage group is connected to the first frame, and the low-voltage group is connected to the second frame. When the first frame and the second frame are connected, the electric field component is an integrated high- and low-voltage electric field component. When the first frame and the second frame are detached and not connected, the electric field component is a separate high- and low-voltage electric field component.

[0022] Both the first and second frames include a first connecting plate, a second connecting plate, a third connecting plate, and a fourth connecting plate connected end-to-end. The first and third connecting plates are side plates. When the first and second frames are connected, the third connecting plate of the first frame and the first connecting plate of the second frame can be omitted. Simultaneously, the second connecting plates of the first and second frames are connected to each other, and the fourth connecting plate of the first and second frames are connected to each other. An air inlet is provided on the first connecting plate of the first frame, and an air outlet is provided on the third connecting plate of the second frame. Oil fumes enter through the air inlet, pass sequentially through the high-pressure group 2 and the low-pressure group 3, and then flow out through the air outlet. When the first and second frames are separated, oil fumes enter through the air inlet of the high-pressure group 2, flow out through the air outlet of the high-pressure group 2, then enter through the air inlet of the low-pressure group 3, and flow out through the air outlet of the low-pressure group 3. The second and fourth connecting plates are end plates. The high-pressure group 2 is connected to the second and fourth connecting plates of the first frame, and the low-pressure group 3 is connected to the second and fourth connecting plates of the second frame.

[0023] The high-voltage group 2 and the low-voltage group 3 are arranged sequentially along the wind direction. The high-voltage group 2 discharges to the oil fumes, charging them, while the low-voltage group 3 is used for oil fume adsorption. The high-voltage group 2 is electrically connected to an external power source, which supplies high voltage to it. The low-voltage group 3 is not connected to an external power source, and the high-voltage group 2 induces discharge to the low-voltage group 3. Furthermore, a high-voltage inductor 21 is installed on the high-voltage group 2, and a low-voltage inductor 31 is installed on the low-voltage group 3. The high-voltage inductor 21 induces discharge to the low-voltage inductor 31, enabling the high-voltage group 2 to supply power to the low-voltage group 3. This ensures safety, and the current magnitude is controllable. Because the current is small, even if the low-voltage group 3 flashes, the overall impact on the electric field components is minimal. The distance between the high-voltage discharge tip 212 of the high-voltage inductor 21 and the low-voltage inductor tip 312 of the low-voltage inductor 31 is adjustable, allowing for adjustable power supply from the high-voltage group 2 to the low-voltage group 3.

[0024] Furthermore, the distance between the high-voltage sensing element 21 and the low-voltage sensing element 31 is set to 5-20mm. The power supply from the high-voltage group 2 to the low-voltage group 3 is adjusted by adjusting the distance between the high-voltage discharge tip 212 of the high-voltage sensing element 21 and the low-voltage sensing tip 312 of the low-voltage sensing element 31. To achieve adjustable distance between the high-voltage sensor 21 and the low-voltage sensor 31, the high-voltage sensor 21 can be movably mounted on the high-voltage group 2, and the low-voltage sensor 31 can be movably mounted on the low-voltage group 3. Furthermore, the movable mounting includes, but is not limited to, detachable mounting, slidable mounting, and rotatable mounting. For example, rotating one or two sensors can adjust the distance between them; disassembling one or two sensors and reconnecting them at different distances between them can also adjust the distance between them. In this solution, the high-voltage sensor 21 is rotatably mounted on the high-voltage group 2, and the low-voltage sensor 31 is rotatably mounted on the low-voltage group 3. When it is necessary to change the power supply level, the high-voltage sensor 21 and / or the low-voltage sensor 31 can be adjusted to adjust the distance between the high-voltage discharge tip 212 of the high-voltage sensor 21 and the low-voltage sensing tip 312 of the low-voltage sensor 31.

[0025] Furthermore, the high-voltage sensing element 21 includes a high-voltage sensing plate 211 and a high-voltage discharge tip 212, the high-voltage sensing plate 211 being connected to the high-voltage group 2; the low-voltage sensing element 31 includes a low-voltage sensing plate 311 and a low-voltage sensing tip 312, the low-voltage sensing plate 311 being connected to the low-voltage group 3; the low-voltage sensing tip 312 and the high-voltage discharge tip 212 are arranged opposite to each other, and by adjusting the high-voltage sensing element 21 and the low-voltage sensing element 31, the distance between the two discharge tips can be adjusted.

[0026] The high-voltage group 2 includes a first high-voltage connecting rod 22, a second high-voltage connecting rod 23, a high-voltage connecting plate 24, a plurality of discharge elements 25, and a plurality of high-voltage electrode plates 26. The high-voltage sensing element 21 is movably disposed on the high-voltage connecting plate 24. Furthermore, the high-voltage sensing plate 211 is rotatably disposed on the high-voltage connecting plate 24. The plurality of discharge elements 25 are spaced apart, and the plurality of high-voltage electrode plates 26 are spaced apart.

[0027] At least one first high-voltage connecting rod 22 is provided; in this embodiment, two first high-voltage connecting rods 22 are provided. The two first high-voltage connecting rods 22 are positioned above and below the first frame, and both ends of the first high-voltage connecting rod 22 are connected to the high-voltage connecting plate 24. Furthermore, a first clearance hole 11 is provided on the first frame at a position relative to the first high-voltage connecting rod 22; that is, a first clearance hole 11 is provided on the second and fourth connecting plates at a position relative to the first high-voltage connecting rod 22. The diameter of the first clearance hole 11 is larger than the diameter of the first high-voltage connecting rod 22. When the first high-voltage connecting rod 22 passes through the first clearance hole 11 and connects to the high-voltage connecting plate 24, the first high-voltage connecting rod 22 does not contact the first frame.

[0028] Furthermore, to ensure a reliable connection between the first high-pressure connecting rod 22 and the high-pressure connecting plate 24, threads are provided at both ends of the first high-pressure connecting rod 22. After the first high-pressure connecting rod 22 passes through the high-pressure connecting plate 24, a nut is provided on the thread at the end of the first high-pressure connecting rod 22 to ensure a tight connection with the high-pressure connecting plate 24. The high-pressure connecting plate 24 is provided at both ends of the first high-pressure connecting rod 22.

[0029] To ensure reliable connection of the high-voltage connecting plate 24, it is connected to the first frame. However, to prevent direct contact between the high-voltage connecting plate 24 and the first frame, they are insulated from each other. Furthermore, an insulator 13 is installed on the first frame, and the high-voltage connecting plate 24 is insulated from the insulator 13.

[0030] The two sides of the high-voltage connecting plate 24 are bent and extended toward the side away from the electric field component, forming an overall U-shaped structure. To accommodate the high-voltage connecting plate 24, the high-voltage sensing plate 211 includes a first connecting part disposed on the high-voltage connecting plate 24, a second connecting part connected to the first connecting part and extending away from the first connecting part, and a third connecting part connected to the second connecting part and extending toward the low-voltage sensing element 31. The second connecting part is in contact with the high-voltage connecting plate 24, and the high-voltage discharge tip 212 is disposed on the third connecting part.

One end of the discharge element 25 is connected to the upper first high-voltage connecting rod 22, and the other end of the discharge element 25 is connected to the lower first high-voltage connecting rod 22.

[0032] Furthermore, the discharge element 25 is configured as an electrode sheet, and discharge tips are provided on the electrode sheet. The discharge tips are evenly and spaced on the electrode sheet. To ensure reliable connection of the electrode sheet, the upper end of the electrode sheet is connected to the upper first high-voltage connecting rod 22, and the lower end of the electrode sheet is connected to the lower first high-voltage connecting rod 22.

[0033] Furthermore, the discharge element 25 is configured as a discharge tungsten wire, with hanging rings at both ends. Springs are mounted on these hanging rings, connecting the discharge tungsten wire to the first high-voltage connecting rod 22 to prevent breakage of the discharge tungsten wire. Even further, to ensure that the springs do not shift on the first high-voltage connecting rod 22 and come into contact with other structures, limiting grooves are provided on the first high-voltage connecting rod 22. The springs are hung within these limiting grooves. The number of limiting grooves is the same as the number of discharge tungsten wires, and they are arranged in a one-to-one correspondence.

[0034] At least one second high-voltage connecting rod 23 is provided; in this embodiment, two second high-voltage connecting rods 23 are provided. The two second high-voltage connecting rods 23 are positioned above and below the high-voltage electrode plate 26, and are connected to the first frame. To ensure reliable connection between the second high-voltage connecting rod 23 and the first frame, threads are provided at both ends of the second high-voltage connecting rod 23. After the second high-voltage connecting rod 23 passes through the second connecting plate and the fourth connecting plate, a nut is provided on the thread at the end of the second high-voltage connecting rod 23 to tightly connect it to the first frame.

[0035] Connection ports are provided on several high-voltage electrode plates 26. The second high-voltage connecting rod 23 passes sequentially through these connection ports, connecting the high-voltage electrode plates 26 to the second high-voltage connecting rod 23 at intervals. After the second high-voltage connecting rod 23 stably connects the high-voltage electrode plates 26 to the first frame, the high-voltage electrode plates 26 do not contact the discharge element 25, nor do they contact the first high-voltage connecting rod 22. Similarly, the second high-voltage connecting rod 23 does not contact the discharge element 25, nor does it contact the first high-voltage connecting rod 22.

[0036] The low-pressure group 3 includes a first low-pressure connecting rod 32, a second low-pressure connecting rod 33, a low-pressure connecting plate 34, a plurality of cathode plates 35 and a plurality of anode plates 36. The cathode plates 35 and anode plates 36 are arranged alternately and at intervals. The low-pressure discharge element is movably arranged on the low-pressure connecting plate 34. Furthermore, the low-pressure sensing plate 311 is rotatably arranged on the low-pressure connecting plate 34.

[0037] At least one first low-pressure connecting rod 32 is provided. In this scheme, to ensure reliable connection of the cathode plate 35, six first low-pressure connecting rods 32 are provided. Two of the six first low-pressure connecting rods 32 are provided at the upper, middle and lower parts of the cathode plate 35, and both ends of the first low-pressure connecting rods 32 are connected to the low-pressure connecting plate 34.

[0038] Furthermore, a connection hole is provided on the cathode plate 35 at a position relative to the first low-pressure connecting rod 32. The first low-pressure connecting rod 32 passes through the connection holes of several cathode plates 35 in sequence to connect several cathode plates 35 to the low-pressure connecting plate 34. Several cathode plates 35 are arranged on the first low-pressure connecting rod 32 and are spaced apart.

[0039] Furthermore, a second clearance hole 12 is provided on the second frame at a position relative to the first low-pressure connecting rod 32. That is, a second clearance hole 12 is provided on the second connecting plate and the fourth connecting plate at a position relative to the first low-pressure connecting rod 32. The diameter of the second clearance hole 12 is larger than the diameter of the first low-pressure connecting rod 32. When the first low-pressure connecting rod 32 passes through the second clearance hole 12 and connects with the low-pressure connecting plate 34, the first low-pressure connecting rod 32 does not contact the second frame.

[0040] Furthermore, to ensure a reliable connection between the first low-pressure connecting rod 32 and the low-pressure connecting plate 34, threads are provided at both ends of the first low-pressure connecting rod 32. After the first low-pressure connecting rod 32 passes through the low-pressure connecting plate 34, a nut is provided on the thread at the end of the first low-pressure connecting rod 32 to ensure a tight connection with the low-pressure connecting plate 34. The low-pressure connecting plate 34 is provided at both ends of the first low-pressure connecting rod 32.

[0041] To ensure reliable connection of the low-voltage connecting plate 34, it is connected to the second frame. However, to avoid direct contact between the low-voltage connecting plate 34 and the second frame, they are insulated from each other. Furthermore, an insulator 13 is installed on the second frame, and the low-voltage connecting plate 34 is insulated from the insulator 13.

[0042] The two sides of the low-voltage connection plate 34 are bent and extended toward the side away from the electric field component, forming an overall U-shaped structure. To accommodate the low-voltage connection plate 34, the low-voltage sensing plate 311 includes a first connecting part disposed on the low-voltage connection plate 34, a second connecting part connected to the first connecting part and extending away from the first connecting part, and a third connecting part connected to the second connecting part and extending toward the high-voltage sensing element 21. The second connecting part is in contact with the low-voltage connection plate 34, and the low-voltage sensing tip 312 is disposed on the third connecting part.

[0043] At least one second low-pressure connecting rod 33 is provided. In this scheme, to ensure reliable connection of the anode plate 36, six second low-pressure connecting rods 33 are provided. Two of the six second low-pressure connecting rods 33 are provided at the upper, middle and lower parts of the anode plate 36, and both ends of the second low-pressure connecting rods 33 are connected to the second frame, that is, connected to the second connecting plate and the fourth connecting plate.

[0044] Furthermore, a connection hole is provided on the anode plate 36 at a position relative to the second low-pressure connecting rod 33. The second low-pressure connecting rod 33 passes through the connection holes of several anode plates 36 in sequence to connect several anode plates 36 to the second frame. Several anode plates 36 are arranged on the second low-pressure connecting rod 33 and are spaced apart.

[0045] Furthermore, to ensure a reliable connection between the second low-pressure connecting rod 33 and the second frame, threads are provided at both ends of the second low-pressure connecting rod 33. After the second low-pressure connecting rod 33 passes through the second frame, a nut is provided on the thread at the end of the second low-pressure connecting rod 33 to tightly connect with the second frame.

[0046] After the anode plate 36 and the cathode plate 35 are connected, the anode plate 36 and the cathode plate 35 are not in contact, the anode plate 36 is not in contact with the first low-pressure connecting rod 32, the cathode plate 35 is not in contact with the second low-pressure connecting rod 33, and the first low-pressure connecting rod 32 and the second low-pressure connecting rod 33 are also not in contact.

[0047] Furthermore, high-voltage sensing elements 21 can be provided at both ends of the high-voltage group 2, and correspondingly, low-voltage sensing elements 31 can be provided at both ends of the low-voltage group 3. Of course, high-voltage sensing elements 21 can also be provided at only one end of the high-voltage group 2, and low-voltage sensing elements 31 can be provided at the same end of the low-voltage group 3. When high-voltage sensing elements 21 are provided at both ends of the high-voltage group 2 and low-voltage sensing elements 31 are provided at both ends of the low-voltage group 3, the power supply effect can be increased.

[0048] This invention mainly designs an adjustable contactless electric field component, which eliminates the need for a separate power supply system for the low-voltage group 3, requiring only the high-voltage group 2 to be powered, thus reducing costs. Since the low-voltage group 3 indirectly obtains its operating voltage through the discharge of the high-voltage group 2, when the low-voltage group 3 experiences a flashover, the protection mechanism of the high-voltage group 2 power supply system will not be triggered, and the high-voltage group 2 can continue to operate stably, effectively avoiding the problem of the entire electric field component shutting down due to the flashover of the low-voltage group 3.
