Description

Technical Field

[0001] This invention relates to the field of high-voltage power supply technology, and in particular to a split-type high-voltage power supply. Background Technology

[0002] High-voltage power supplies are core equipment in scientific research and industrial fields such as accelerators, ion implanters, electron beam / ion beam systems, X-ray systems, electrostatic precipitation, and ion and chemical vapor deposition. For split high-voltage power supplies with ultra-high voltage levels (60kV and above), they typically adopt a combined structure of high-voltage section and drive section. The high-voltage section is the core high-voltage output unit, including voltage doubler rectification, filtering and shock protection sections, and voltage equalization sections, which need to bear ultra-high voltages of 60kV~1500kV. The drive section consists of a low-voltage control unit and an inverter unit, which is responsible for controlling the output PWM drive signal and the inverter section to realize high-voltage voltage and current control and high-voltage transformer output.

[0003] In existing technologies, the high-voltage tower and the inverter box are connected by two high-voltage cables, involving the matching of four high-voltage plugs and corresponding sockets. In actual applications, due to factors such as installation and operation deviations, equipment vibration, and long-term wear and tear, it is very easy for some plugs to be not fully inserted, loose, or even poorly connected. However, existing high-voltage power supply systems can still start normally and output high voltage under such poor connection conditions, which can lead to serious safety hazards.

[0004] Furthermore, the existing high-voltage sealed insulation chambers of separate high-voltage power supplies still have many technical defects in actual use, leading to gradual deterioration of the power supply insulation performance and limited operational stability and service life. For example, when the high-voltage generating unit is working, Joule heat and dielectric loss heat are generated, causing the insulating air inside the chamber to heat up and expand, with the internal pressure exceeding the external atmospheric pressure. Dry and pure insulating air is prone to leaking from the chamber's sealing gaps and cable penetration points. After shutdown, the air inside the chamber cools down and contracts, forming a slight negative pressure inside. Unfiltered humid air, dust, oil mist, and corrosive gases from the outside are drawn into the chamber. Repeated "thermal expansion and leakage - cold contraction and impurity absorption" will continuously deteriorate the insulating air environment inside the chamber, reduce the air breakdown field strength, and easily cause insulation faults such as surface flashover and air breakdown.

[0005] Therefore, this application proposes a highly protected and highly stable split high-voltage power supply. Summary of the Invention

[0006] The purpose of this invention is to solve the problems in the prior art by proposing a separate high-voltage power supply.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A split high-voltage power supply includes an inverter box and a high-voltage tower. The inverter box is connected to the high-voltage tower via two cables. The socket surfaces of the inverter box and the high-voltage tower are respectively provided with protective components. The protective components include a switch fixed to the socket surface and a pressure plate for pressing the switch.

[0009] The high-pressure tower has a sealed tube fixed inside for storing dry air, and a constant pressure component is provided at the bottom of the sealed tube to maintain a stable internal pressure.

[0010] In some embodiments, one end of the pressure plate is hinged to a release plate for quick separation from the switch, the release plate abutting against the switch surface via a release assembly.

[0011] In some embodiments, the constant pressure assembly includes a tank fixed inside the high pressure tower and a piston plate sliding inside the tank.

[0012] In some embodiments, the disengagement assembly includes a limiting plate for limiting the angle of the disengagement plate and a rocker for moving the limiting plate up and down, wherein the end of the rocker away from the limiting plate abuts against an electric push rod.

[0013] In some embodiments, the pressure plate with the release plate is rotatably connected to the surface of the guide ring, the guide ring is fixed to the surface of the inverter box, the guide ring is concentrically arranged with the socket, and the surface of the guide ring is provided with two spiral protrusions.

[0014] In some embodiments, two connecting pipes are fixed to the top of the tank, and the upper ends of the two connecting pipes are connected to the bottom of the sealing pipe. A spring for pushing the piston plate to slide upward is fixed to the bottom of the piston plate.

[0015] In some embodiments, the surface of the tank is provided with a groove for installing a filter, the filter is threaded to the top of the groove, and the bottom of another connecting pipe is fixed with a fan for drawing air from the sealed pipe into the tank. One-way valves are provided on the surfaces of the two connecting pipes respectively.

[0016] In some embodiments, a guide tube is fixed to the top of the connecting tube corresponding to the filter. The guide tube is located inside the sealing tube and is spiral-shaped to allow the air entering the sealing tube to flow spirally upward.

[0017] In some embodiments, the tank is provided with a closure assembly for sealing the mounting hole when the filter is replaced, the closure assembly being concentrically arranged with the filter.

[0018] In some embodiments, a protective tube is fitted over the surface of the cable, and both ends of the protective tube are fixed to the cable via connectors. Multiple clamps are hinged to the inner wall of the connectors, and the clamps are held on the surface of the cable by push rings.

[0019] Compared with the prior art, the present invention provides a separate high-voltage power supply with the following beneficial effects.

[0020] 1. This invention, by setting up a protective component, when the cable plug is fully inserted into the socket, the plug pushes the pressure plate to press and close the switch, causing the pressure plate to trigger the switch and start the high-voltage power supply. When any plug is not fully inserted or is loose, the pressure plate does not fully press the switch, and the circuit of the protective component cannot be energized, thereby ensuring that each high-voltage plug outputs high-voltage current when fully inserted, and avoiding the high-voltage power supply from catching fire due to the plug not being properly inserted into the socket.

[0021] 2. In this invention, by setting a constant pressure component, when the air inside the sealed tube is heated and expands, the high-pressure air pushes the piston plate to slide downward, expanding the air storage space at the top of the tank and relieving the air pressure after expansion; when the equipment stops working, the air inside the sealed tube cools and contracts, and the resulting negative pressure drives the piston plate to slide upward, allowing the air inside the tank to enter the sealed tube, thus preventing the generation of negative pressure inside the sealed tube and allowing humid air from the outside to invade the sealed tube.

[0022] Other advantages, objectives and features of the invention will be set forth in part in the description which follows; and in part will be apparent to those skilled in the art upon examination of the following description; or may be learned from practice of the invention.

[0041] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0042] Reference Figure 1-16 A split high-voltage power supply includes an inverter box 1 and a high-voltage tower 2. The inverter box 1 is connected to the high-voltage tower 2 via two cables 3. Both the inverter box 1 and the high-voltage tower 2 are existing technologies and will not be described in detail. The socket surfaces of the inverter box 1 and the high-voltage tower 2 are respectively provided with protective components 4. The protective components 4 include a switch 401 fixed on the socket surface and a pressure plate 402 for pressing the switch 401. Multiple pressure plates 402 slide on the socket surface via guide rods 403. The pressure plates 402 are separated from the switch 401 by two first elastic plates 404. The first elastic plates 404 are fixed on the socket surface.

[0043] Understandably, when cable 3 plug is fully inserted into the socket, the plug thread is connected to the socket surface, thereby pushing pressure plate 402 to press and close switch 401, causing pressure plate 402 to trigger switch 401. When all plugs are plugged into the socket, multiple switches 401 close, relay K1 coil is energized, contact 2-3 becomes 2-4, high voltage power supply HV ENABLE is activated, high voltage power supply signal is sent out, and high voltage power supply starts. If any plug is not fully inserted or is loose, pressure plate 402 does not fully press switch 401, and protection component 4 circuit cannot be energized, thus ensuring that high voltage current is output when each high voltage plug is fully inserted, avoiding high voltage power supply fire caused by plug not being properly inserted into the socket.

[0044] Specifically, one of the pressure plates 402 has a release plate 4021 hinged at its end for quick separation from the switch 401. The release plate 4021 abuts against the surface of the switch 401 via a release assembly 5. The release assembly 5 includes a limiting plate 501 for limiting the angle of the release plate 4021 and a rocker plate 502 for moving the limiting plate 501 up and down. The end of the rocker plate 502 away from the limiting plate 501 abuts against an electric push rod 503. The electric push rod 503 is located above the rocker plate 502 and fixed to the top of the housing 504. The housing 504 is fixed to the surface of the inverter box 1. The rocker plate 502 rotates on the inner wall of the housing 504. A lever is fixed to the end of the rocker plate 502 near the limiting plate 501. The lever extends out of the outer side of the housing 504. A torsion spring for driving the limiting plate 501 to rotate downward is sleeved on the surface of the rotating shaft of the rocker plate 502.

[0045] It is understandable that when some core modules of the high-voltage power supply malfunction, the high-voltage power supply may not stop outputting high-voltage current in time, which could easily damage other modules during continuous operation. Therefore, to avoid damage to other modules, corresponding detection sensors are installed on some core modules, such as temperature sensors, current sensors, or voltage detection circuits on the power module, transformer, rectifier and filter module, and grounding terminal, to monitor the working status of these core modules in real time. When the detected value exceeds the threshold, a signal is sent to the electric push rod 503 to push the rocker 502 to rotate, causing the limit plate 501 to rise and separate from the release plate 4021, thereby releasing the resistance to the switch 401, causing the switch 401 to open, de-energizing the entire high-voltage circuit, stopping the output of high-voltage current, and thus preventing other modules from being affected and damaged. When connecting the cable 3, the cable 3 connector abuts against the surface of the pressure plate 402 and rotates the release plate 4021, abutting against the switch 401. At this time, the rocker 502 drives the limit plate 501 to move downward to prevent the release plate 4021 from separating from the switch 401.

[0046] Specifically, the pressure plate 402 with release plate 4021 is rotatably connected to the surface of guide ring 4022. Guide ring 4022 is fixed to the surface of inverter box 1. Guide ring 4022 is concentrically set with the socket. Two spiral protrusions 4023 are provided on the surface of guide ring 4022.

[0047] Understandably, the pressure plate 402 with the release plate 4021 is not restricted by the guide rod 403 and can rotate on the surface of the guide ring 4022. By setting the spiral protrusion 4023, when the plug abuts against the pressure plate 402 and presses the pressure plate 402, the pressure plate 402 and the release plate 4021 remain horizontal. The release plate 4021 abuts against the surface of the switch 401 through the release component 5. When the plug is loosened, the first elastic plate 404 pushes the pressure plate 402 to slide outward. Under the action of the spiral protrusion 4023, the pressure plate 402 rotates during the sliding process, so that the release plate 4021 can be properly separated from the switch 401. This avoids the restriction of the release component 5, which would affect the separation of the pressure plate 402 from the switch 401 and cause the loss of the protection function for the high voltage circuit.

[0048] Specifically, a sealed tube 6 for storing dry air is fixed inside the high-pressure tower 2. The sealed tube 6 is existing technology and will not be described in detail. A constant pressure component 7 for maintaining stable internal pressure is provided at the bottom of the sealed tube 6. The constant pressure component 7 includes a tank 701 fixed inside the high-pressure tower 2 and a piston plate 703 sliding inside the tank 701. Two connecting pipes 702 are fixed at the top of the tank 701. The upper ends of the two connecting pipes 702 are connected to the bottom of the sealed tube 6. A spring 7031 for pushing the piston plate 703 to slide upward is fixed at the bottom of the piston plate 703.

[0049] Understandably, by setting up the constant pressure component 7, when the air inside the sealing tube 6 is heated and expands, it enters the tank 701 through the connecting pipe 702. The high-pressure air pushes the piston plate 703 to slide downward, expanding the air storage space at the top of the tank 701, relieving the air pressure after expansion, and preventing excessive leakage of dry air in the high-pressure tube due to excessive pressure. When the equipment stops working, the air inside the sealing tube 6 cools and contracts, and the resulting negative pressure drives the piston plate 703 to slide upward, reducing the air storage space at the top of the tank 701, allowing the air inside the tank 701 to enter the sealing tube 6, preventing the generation of negative pressure inside the sealing tube 6, which would allow humid air from the outside to invade the sealing tube 6.

[0050] Specifically, the surface of the tank 701 is provided with a groove 7011 for installing a filter 704. The filter 704 is threadedly connected to the top of the groove 7011. The filter 704 corresponds to one of the connecting pipes 702. The bottom of the other connecting pipe 702 is fixed with a fan 705 for drawing air from the sealing pipe 6 into the tank 701. The surfaces of the two connecting pipes 702 are respectively provided with one-way valves 7021. The one-way valve 7021 on the surface of the connecting pipe 702 corresponding to the fan 705 is used to prevent air from entering the sealing pipe 6 from the tank 701. The one-way valve 7021 on the surface of the connecting pipe 702 corresponding to the filter 704 is used to prevent air from entering the tank 701 from the sealing pipe 6.

[0051] The filter 704 has a pre-filter made of polyester fiber for filtering dust. The pre-filter is ring-shaped and contains a molecular sieve.

[0052] A guide tube 706 is fixed to the top of the connecting tube 702 corresponding to the filter 704. The guide tube 706 is located inside the sealing tube 6 and is spiral-shaped to allow the air entering the sealing tube 6 to flow upward spirally.

[0053] Understandably, due to the breathing effect of dry air, air leakage and the entry of humid air from the outside are inevitable. Therefore, by setting up a filter 704, the air inside the sealed tube 6 is filtered and cleaned to maintain the purity of the dry air inside the sealed tube 6 and improve the service life of the equipment. When filtering air, the high-pressure tower 2 needs to be stopped. The fan 705 drives the air from the sealed tube 6 into the tank 701, and then into the filter 704 for dust removal and dehumidification. The air then enters the sealed tube 6 through another connecting pipe 702, forming an air circulation, thereby filtering the air and keeping it pure. By setting up a spiral guide pipe 706, the air passing through... The filtered dry air spirals upward within the sealed tube 6, replacing the air above. A one-way valve 7021 ensures that air can only enter the tank 701 from the sealed tube 6 via the connecting pipe 702 where the fan 705 is located, and then return to the sealed tube 6 from the connecting pipe 702 where the filter 704 is located, forming a directional circulation filtration path. This prevents irregular airflow within the tank 701 from affecting filtration efficiency. The filter 704 is threaded onto the top of the groove 7011, facilitating future maintenance and replacement. After a certain period of use, the filter 704 can be directly unscrewed for cleaning or replacement of the internal polyester fiber pre-filter and molecular sieve, making operation convenient and reducing maintenance costs.

[0054] Specifically, the tank body 701 is provided with a closure assembly 8 for sealing the mounting hole when the filter 704 is replaced. The closure assembly 8 is concentrically arranged with the filter 704. The closure assembly 8 includes a first collar 801 fixed to the inner wall of the tank body 701 and a second collar 802 that slides vertically on the inner wall of the first collar 801. The surfaces of the first collar 801 and the second collar 802 are respectively provided with vent holes. Two top blocks 803 are fixed to the top of the inner wall of the second collar 802. The top of the filter 704 is fixed with a top ring 804 that pushes the top blocks 803. The top of the tank body 701 is fixed with a second elastic plate 805 that pushes the second collar 802 to slide downward.

[0055] Understandably, during filter 704 replacement, outside air enters the tank 701 and sealing pipe 6 through the mounting hole, bringing in a large amount of moisture and dust. Therefore, a closing assembly 8 is provided. When filter 704 is screwed onto the top of groove 7011, its top ring 804 simultaneously pushes the top block 803 and the second ring 802 upwards, causing the vent holes on the surfaces of the first ring 801 and the second ring 802 to completely overlap. At this time, filter 704 is connected to the inside of tank 701, allowing normal air filtration and circulation. When filter replacement is required... At step 704, during the process of unscrewing the filter 704, the squeezing force of the top ring 804 on the top block 803 gradually disappears. The rebound force of the second elastic plate 805 pushes the second ring 802 to slide downward, causing the vent holes of the first ring 801 and the second ring 802 to be misaligned. This seals the internal channel of the tank 701 where the filter 704 mounting hole is located, effectively preventing unfiltered humid air, dust and other impurities from the outside from directly entering the tank 701 and the interior of the sealing tube 6 through the mounting hole when replacing the filter 704, thus ensuring the purity of the insulating air environment inside the sealing tube 6.

[0056] Specifically, a protective tube 9 is fitted on the surface of the cable 3. Both ends of the protective tube 9 are fixed to the cable 3 through connectors 901. Multiple clamps 902 are hinged to the inner wall of the connector 901. A torsion spring is fitted on the rotating shaft surface of the clamp 902 to drive the clamp 902 to separate from the cable 3. The clamp 902 is clamped on the surface of the cable 3 by a push ring 903. The push ring 903 is threaded to the surface of the connector 901. A stepped ring that pushes the clamp 902 to rotate is fixed on the inner wall of the push ring 903. The protective tube 9 is a spiral telescopic tube.

[0057] Understandably, by setting up the protective tube 9, the insulation layer of the cable 3 is protected, preventing damage to the insulation layer caused by external friction, compression, or environmental corrosion during long-term use, which could lead to safety hazards such as leakage or short circuits. The protective tube 9 is a spiral telescopic tube, and its length can be adjusted according to the length of the cable 3 to fit it. By setting up clamping plates 902, after the cable 3 is inserted into the protective tube 9, rotating the push ring 903 causes the push ring 903 to drive the stepped ring to push the clamping plates 902 to rotate, so that multiple clamping plates 902 clamp the cable 3, achieving a firm connection between the protective tube 9 and the cable 3, and preventing the cable 3 from being exposed due to the rebound of the spiral telescopic tube, which would affect the protection of the cable 3. When disassembling, rotating the push ring 903 in the opposite direction loosens the cable 3, and the torsion spring drives the clamping plates 902 to reset and separate from the cable 3. The operation is simple and convenient, and the installation length of the protective tube 9 can be flexibly adjusted according to the length of the cable 3, which is suitable for the cable 3 protection needs in different scenarios.

[0058] Specifically, the connector 901 has a nut 9011 threaded onto its surface. The connector 901 is fixed to the surface of the fixing plate 10 by the nut 9011. The fixing plate 10 is U-shaped and is fixed to the surface of the inverter box 1.

[0059] Understandably, by inserting the connector 901 into the surface of the fixing plate 10 and clamping the fixing plate 10 with the nut 9011, the connector 901 is fixed to the surface of the fixing plate 10. This tightly fixes the end of the protective tube 9 to the fixing plate 10. The stable connection between the U-shaped fixing plate 10 and the inverter box 1 provides reliable support for the protective tube 9 and the internal cable 3, preventing the plug and socket connection at the inverter box 1 from loosening due to the cable 3's own weight or external pulling force. This further ensures the stability and safety of the overall high-voltage power supply connection.

[0060] In this invention, when connecting the inverter box 1 and the high-voltage tower 2, the protective tube 9 is fitted onto the surface of the cable 3, and the push ring 903 is rotated, causing the push ring 903 to drive the stepped ring to push the clamping plate 902 to rotate, so that multiple clamping plates 902 clamp the cable 3, achieving a firm connection between the protective tube 9 and the cable 3, and preventing the cable 3 from being exposed due to the rebound of the spiral telescopic rod, which would affect the protection of the cable 3; then, the connector 901 is fixed to the surface of the fixing plate 10 by the nut 9011, the cable 3 plug is inserted into the socket, the plug is threaded onto the surface of the socket, and the pressure plate 402 is pushed to switch 401. Pressing the switch closes the pressure plate 402, triggering switch 401. When all plugs are inserted into the socket, multiple switches 401 close, energizing the relay K1 coil. Contacts 2-3 and 2-4 change from being closed to open, enabling the high-voltage power supply HVENABLE. A high-voltage power supply signal is sent, and the high-voltage power supply starts. If any plug is not fully inserted or is loose, the pressure plate 402 does not fully press switch 401, and the protection component 4 circuit cannot be energized. This ensures that a high-voltage current is output when each high-voltage plug is fully inserted, preventing high-voltage power supply failure due to improper plug insertion. In the event of a fire, during operation, if any core module of the high-voltage power supply malfunctions, a signal is sent to the electric push rod 503, causing the rocker arm 502 to rotate. This rotates the limit plate 501, causing it to rise and separate from the release plate 4021, thereby releasing the resistance to the switch 401 and causing it to open. This disconnects the entire high-voltage circuit, stopping the output of high-voltage current and preventing other modules from being affected and damaged. Furthermore, by setting up the constant pressure component 7, when the air inside the sealing tube 6 expands due to heat, it enters the tank 701 through the connecting pipe 702. The high-pressure air pushes the piston plate 703 downwards. The air storage space at the top of the tank 701 is expanded to alleviate the air pressure after expansion and prevent excessive leakage of dry air from the high-pressure pipe due to excessive pressure. When the equipment stops working, the air in the sealing pipe 6 cools and contracts, and the resulting negative pressure drives the piston plate 703 to slide upward, reducing the air storage space at the top of the tank 701. This allows the air in the tank 701 to enter the sealing pipe 6, preventing negative pressure from being generated in the sealing pipe 6 and allowing humid air from the outside to enter the sealing pipe 6. Under the action of the filter 704, the dry air in the sealing pipe 6 is filtered periodically to keep it pure.
