Description

Technical Field

[0001] This invention relates to the field of instrument transformer technology, specifically a high-voltage voltage transformer. Background Technology

[0002] High-voltage transformers are indispensable key equipment in power systems. Their core function is to reduce the high voltage of the power grid by a precise ratio, providing standard and safe low-voltage signals for metering instruments, relay protection and automatic control devices.

[0003] The main technical bottlenecks faced by traditional high-voltage voltage transformers:

[0004] During operation, the hysteresis loss and eddy current loss (collectively known as iron loss) of the iron core of the instrument transformer make it a major heat source. Traditional heat dissipation methods, such as oil-immersed self-cooling (ONAN) or oil-immersed air-cooling (ONAF), rely on the natural convection of insulating oil and external heat sinks, which is essentially a kind of "surface cooling". This method is inefficient and cannot effectively cool the hottest "hot spots" inside the equipment (usually deep in the iron core). Long-term overheating will seriously accelerate the aging of the insulation material, shorten the equipment life, and even cause catastrophic accidents such as insulation breakdown.

[0005] To compensate for the inefficiency of natural heat dissipation, traditional instrument transformers have to be equipped with large oil tanks and a large number of external heat sinks, resulting in huge equipment size, weight and footprint, which is not suitable for the development trend of compact and miniaturized modern substations.

[0009] Two sets of sealing connection components are respectively set on both sides of the internal partition plate, and the inner cavity of the central shell away from the coalescing layer is connected to the inner cavity of the high voltage transformer body through the sealing connection components. The two sides of the central shell are fixed to the bottom fixing component by bolts.

[0013] The outer wall of the operating sleeve also includes a lever.

[0014] As a preferred technical solution of the present invention: the iron core module includes an iron core body, the inner cavity of the iron core body is provided with an internal cooling channel, the bottom sides of the iron core body are provided with oil inlet and outlet ports communicating with the internal cooling channel, the inner cavity of the internal cooling channel at the bottom is inclinedly provided with an isolation plate, the inner wall of the oil inlet and outlet ports is fixedly equipped with an optical fiber temperature sensor, the top of the iron core body is sleeved with a first winding, and the outer wall of the first winding is sleeved with a second winding.

[0015] As a preferred embodiment of the present invention, the inner cavity of the internal cooling channel is provided with a turbulence structure, and the cross-section of the channel can be designed to be non-circular.

[0016] As a preferred technical solution of the present invention: the magnetic drive circulation component includes a pump body, both ends of the pump body are fixedly equipped with connecting end pipes, the outer wall of the pump body is sleeved with a stator housing, both sides of the stator housing are fixedly equipped with stator winding assemblies, the stator housing, the stator winding assemblies and the pump body are externally sleeved with an electromagnetic shielding layer, and an acoustic sensor is fixedly installed on the outer wall of the electromagnetic shielding layer.

[0020] The present invention has the following beneficial effects:

[0021] 1. This high-voltage transformer, by employing a hollow iron core combined with internal forced circulation cooling, achieves a transformation from "surface cooling" to "source cooling." The cooling medium directly and rapidly flushes the core heat source, greatly improving heat dissipation efficiency and effectively eliminating internal "hot spots" that are difficult to reach in traditional equipment. This fundamentally slows down the aging rate of insulation materials, improving the operational reliability and service life of the equipment.

[0022] 2. This high-voltage transformer integrates a multi-dimensional online sensing system and intelligent diagnostic module, which monitors key parameters such as temperature, vibration, and oil status inside the equipment in real time and continuously. It realizes the leap from "post-event diagnosis" to "predictive maintenance". The system can provide early warning of potential faults and provide operators with accurate maintenance suggestions, which greatly improves the manageability and safety of the equipment and reduces the maintenance cost throughout the entire life cycle.

[0023] 3. This high-voltage transformer achieves continuous purification of insulating oil through its built-in online heat exchange and purification center. While the circulating oil is cooled, trace amounts of moisture and solid impurities inside are efficiently filtered out online, ensuring that the insulating oil maintains a high level of cleanliness and high insulation strength over a long period of time. This avoids performance degradation, eliminates the tedious work of periodically shutting down the power for offline oil filtration, and ensures long-term stable operation of the equipment.

[0043] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0044] Please see Figure 1 - Figure 11 A high-voltage transformer includes a high-voltage transformer body 1. Side wall heat dissipation plates 2 are fixedly mounted on both outer walls of the high-voltage transformer body 1. An end wall connection terminal 3 is fixedly mounted on one outer wall of the high-voltage transformer body 1. A top connection terminal 4 is fixedly mounted on the top of the high-voltage transformer body 1. Bottom fixing parts 5 are fixedly mounted on the bottom outer walls of both ends of the high-voltage transformer body 1. A heat exchange and purification center 6 is provided at the bottom of the high-voltage transformer body 1. A sealing connection component 7 is connected to the top of the heat exchange and purification center 6. A bottom mounting base 8 is fixedly mounted on the bottom inner wall of the high-voltage transformer body 1. Two sets of iron core modules 9 are fixedly mounted on the top of the bottom mounting base 8. A magnetic drive circulation component 10 is fixedly mounted between the two sets of iron core modules 9. The bottom inner wall of the iron core module 9 is fixedly mounted to the bottom mounting base 8 via a connector 11. An outlet connection pipe 12 is fixedly mounted on the bottom outer side of one set of iron core modules 9.

[0045] In a preferred embodiment: the heat exchange and purification center 6 includes a central shell 601, with side wall heat dissipation plates 602 fixedly mounted on both outer walls of the central shell 601, an internal partition plate 603 fixedly mounted in the middle of the inner cavity of the central shell 601, an adsorption layer 604 and a coalescence layer 605 respectively provided on both sides of the internal partition plate 603, and a base 606 fixedly mounted on the bottom of the central shell 601.

[0046] Two sets of sealing connection components 7 are respectively set on both sides of the internal partition plate 603, and the inner cavity of the central housing 601 away from the coalescing layer 605 is connected to the inner cavity of the high voltage transformer body 1 through the sealing connection component 7. The two sides of the central housing 601 are fixed to the bottom fixing component 5 by bolts.

[0047] In the above structure, the inner cavity of the central shell 601 is partially isolated by the internal partition plate 603. By setting an adsorption layer 604 and a coalescing layer 605, the insulating oil flowing through the inner cavity of the heat exchange purification center 6 can unidirectionally flow through the channel formed by the internal partition plate 603 and the central shell 601. It undergoes first-stage adsorption through the coalescing layer 605. The coalescing layer 605, made of hydrophobic / hydrophilic composite fiber material, captures and merges micro-water droplets when insulating oil containing tiny water molecules flows through it, forming larger droplets for easier subsequent processing. Simultaneously, this layer also filters solid impurities.

[0048] The second stage, adsorption layer 604, follows immediately after coalescence layer 605 and is composed of highly efficient molecular sieves or superabsorbent resin. It efficiently adsorbs the trace amounts of residual, uncoalesced dissolved water in the oil, maintaining the dryness of the oil, while the heat exchange purification center 6 further dissipates heat from the insulating oil.

[0049] Meanwhile, the heat exchange purification center 6 and the high-voltage transformer body 1 are connected by the sealed connection component 7, so that the heat exchange purification center 6 can be disassembled and replaced.

[0050] In a preferred embodiment: the sealing connection component 7 includes a connecting pipe body 701, with a rotary joint 702 rotatably connected to both the upper and lower ends of the connecting pipe body 701, and an operating sleeve 704 sleeved on the outer wall of the connecting pipe body 701.

[0051] In a preferred embodiment: the connecting pipe body 701 includes a fixed sealing surface 705 fixedly assembled on the inner wall, and an indicator port 706 is provided on one side of the outer wall of the connecting pipe body 701.

[0052] The rotary joint 702 includes a sealing ring 703 sleeved on the outer wall near one end of the connecting pipe body 701, a hexagonal ring 707 fixedly assembled on the outer wall of the rotary joint 702, an indicator port 709 opened on one side of the outer wall of the hexagonal ring 707, and a rotary sealing surface 708 fixedly assembled on the inner wall of the rotary joint 702.

[0053] The outer wall of the operating sleeve 704 also includes a lever 710.

[0054] In the above structure, two sets of rotary joints 702 are set at the upper and lower ends of the connecting pipe body 701. The upper and lower sets of rotary sealing surfaces 708 and fixed sealing surfaces 705 are used for sealing, so that the sealing connection component 7 is sealed. The rotary joint 702 and the connecting pipe body 701 are sealed by the sealing ring 703, so that the rotary joint 702 and the connecting pipe body 701 can rotate relative to each other.

[0055] The indicator ports 706 and 709 allow personnel to identify the rotation angle between the rotating sealing surface 708 and the fixed sealing surface 705.

[0056] In actual use, a set of rotary joints 702 are threadedly connected to the heat exchange and purification center 6. Then, the connecting pipe body 701 and another set of rotary joints 702 are simultaneously sleeved through the operating sleeve 704. The operating sleeve 704 drives the connecting pipe body 701 and the rotary joints 702 to rotate simultaneously, so that the second set of rotary joints 702 is threadedly connected to the heat exchange and purification center 6. When the operating sleeve 704 drives the connecting pipe body 701 and the second set of rotary joints 702 to rotate simultaneously, the rotary sealing surface 708 in the second set of rotary joints 702 and the fixed sealing surface 705 in the connecting pipe body 701 are closed, so that the sealing connection component 7 can still achieve sealing in the installation and disassembly states.

[0057] In a preferred embodiment: the core module 9 includes a core body 901, an internal cooling channel 902 is provided in the inner cavity of the core body 901, oil inlet and outlet ports 903 communicating with the internal cooling channel 902 are provided on both sides of the bottom of the core body 901, an isolation inclined plate 904 is inclinedly provided in the inner cavity of the internal cooling channel 902 located at the bottom, an optical fiber temperature sensor 905 is fixedly installed on the inner wall of the oil inlet and outlet ports 903, a first winding 906 is sleeved on the top of the core body 901, and a second winding 907 is sleeved on the outer wall of the first winding 906.

[0058] In the above structure, the inclined isolation plate 904 divides the oil inlet and outlet 903 at the bottom of the iron core body 901 into an inlet and an outlet, and at the same time divides the internal cooling channel 902, so that the insulating oil enters the internal cooling channel 902 through the oil inlet and outlet 903 on one side and is discharged from the oil inlet and outlet 903 on the other side, thereby realizing the circulation of the insulating oil in the inner cavity of the iron core body 901.

[0059] By arranging a fiber optic temperature sensor 905 at each of the inlet and outlet of the two sets of iron core modules 9, the temperature rise can be accurately measured and the heat dissipation power can be calculated in real time.

[0060] In a preferred embodiment, the inner cavity of the internal cooling channel 902 is provided with a turbulence structure, and the cross-section of the channel can be designed to be non-circular.

[0061] In the above structure, by designing turbulence structures such as spiral grooves or pits, the cross-section of the channel is designed to be non-circular, such as elliptical or ribbed, in order to induce secondary vortices and further enhance heat transfer.

[0062] In a preferred embodiment: the magnetically driven circulation component 10 includes a pump body 1001, with connecting end pipes 1002 fixedly mounted at both ends of the pump body 1001, a stator housing 1003 sleeved on the outer wall of the pump body 1001, stator winding assemblies 1004 fixedly mounted on both sides of the stator housing 1003, and an electromagnetic shielding layer 1005 sleeved on the outside of the stator housing 1003, the stator winding assembly 1004 and part of the pump body 1001, with an acoustic sensor 1006 fixedly mounted on the outer wall of the electromagnetic shielding layer 1005.

[0063] In a preferred embodiment: an internal rotor assembly 1007 is fixedly mounted on the inner wall of the pump body 1001;

[0064] The inner cavity of the stator winding assembly 1004 is provided with a plurality of inclined stator skew windings 10041;

[0065] The internal rotor assembly 1007 includes a rotor body 10071, with impellers 10072 rotatably connected to both ends of the rotor body 10071, and permanent magnets 10073 embedded at the blade ends of the impellers 10072.

[0066] In the above structure, the internal rotor assembly 1007 is fixedly mounted in the inner cavity of the pump body 1001 via the rotor body 10071, and the permanent magnet 10073 is driven by the stator skew winding 10041 embedded in the inner cavity of the stator winding assembly 1004, so that the impeller 10072 can rotate in the inner cavity of the pump body 1001, thereby pushing the insulating oil.

[0067] The electromagnetic shielding layer 1005 is designed with a double-layer structure. The inner layer is made of permalloy with high magnetic permeability to guide low-frequency driving magnetic fields; the outer layer is made of copper or aluminum foil with high electrical conductivity to shield high-frequency electromagnetic noise and achieve wide-bandwidth electromagnetic isolation.

[0068] By attaching the acoustic sensor 1006 to the outer wall of the electromagnetic shielding layer 1005, it is used to capture the acoustic wave signal generated by abnormal vibration or partial discharge of the pump.

[0069] The magnetic drive circulation component 10 connects the oil inlet and outlet ports 903 at opposite ends of the two sets of iron core modules 9, so that the two sets of internal cooling channels 902 are connected through the magnetic drive circulation component 10. The internal rotor assembly 1007 in the magnetic drive circulation component 10 drives the insulating oil. The oil inlet and outlet ports 903 at the outlet end of one set of iron core modules 9 are connected to the heat exchange purification center 6 through the outlet connecting pipe 12 and a set of sealing connection components 7. The heat exchange purification center 6 and the high voltage transformer body 1 are directly connected through another set of sealing connection components 7, thereby realizing the circulation of insulating oil in the heat exchange purification center 6, iron core modules 9, and high voltage transformer body 1.

[0070] Specifically, the stator winding assembly 1004, located outside the component, is powered by an independent external frequency converter. When current flows through the stator skewed winding 10041, a smooth and continuous rotating magnetic field is generated. The rotation speed of the magnetic field is determined by the frequency of the external power supply. The entire stator assembly is encapsulated within the stator housing 1003 and connected to the current transformer body.

[0071] The rotating magnetic field ignores physical isolation and directly penetrates the stationary, non-magnetic pump body 1001 wall. The pump body 1001 wall acts as an isolation sleeve, completely separating the external stator from the internal rotor, ensuring the absolute seal of the entire transformer system. After penetrating the pump body 1001 wall, the rotating magnetic field enters the transformer and directly acts on the internal rotor assembly 1007, which is completely immersed in insulating oil.

[0072] Multiple high-performance permanent magnets 10073 are embedded on the rotor body 10071 of the internal rotor assembly 1007. The external rotating magnetic field interacts with the permanent magnets 10073 to generate a magnetic driving torque.

[0073] Under the action of torque, the internal rotor assembly 1007 is "dragged" to rotate synchronously with the external rotating magnetic field, and the impeller 10072, which is integrally formed with the rotor body 10071, also rotates at high speed. The rotating impeller 10072 pressurizes and pushes the surrounding insulating oil, forcing the insulating oil to flow directionally and at high speed in the internal cooling channel 902 of the iron core module 9, thereby completing one cooling cycle.

[0074] The electromagnetic shielding layer 1005, which is sleeved on the outside of the stator assembly, is used to "capture" and confine the stray magnetic field driven inside itself, preventing these magnetic fields from leaking and interfering with the windings 906 and 907 on the core module 9 used for precision measurement, thereby ensuring that the measurement accuracy of the transformer is not affected by the operation of the cooling system.

[0075] The acoustic sensor 1006, installed on the outer wall of the shielding layer, can monitor the vibration and sound waves generated by the pump in real time during operation. By analyzing these signals, it is possible to determine whether the pump bearings are worn, whether the impeller 10072 is unbalanced, or whether there are air bubbles, thus enabling predictive maintenance of the pump's health status.

[0076] Working principle: When the equipment is put into operation, the high voltage of the power grid is applied to the winding 906 of the main body 1 of the high voltage transformer. According to the principle of electromagnetic induction, an alternating magnetic flux is generated in the iron core body 901. This magnetic flux then induces a low voltage in the winding 907 that is precisely proportional to the primary voltage. This signal is output through the end wall connection terminal 3 or the top connection terminal 4 to complete its basic measurement and protection functions.

[0077] During voltage transformation, the iron core body 901 continuously heats up due to iron loss. At this time, the intelligent control system activates the magnetic drive circulation component 10. The external stator of the magnetic drive circulation component 10 generates a rotating magnetic field, which drives the completely sealed internal rotor assembly 1007 to rotate at high speed in a non-contact manner. The rotating impeller 10072 pushes the insulating oil to form a controlled internal circulation.

[0078] Cooled insulating oil is pumped into the inlet / outlet 903 of one of the core modules 9, flowing through the internal cooling channel 902 at the center of the core. During this process, the oil directly washes over the heat source core, efficiently carrying away heat through forced convection. The turbulence structure within the channel further enhances the heat transfer effect.

[0079] The insulating oil carrying heat flows out from another inlet / outlet 903, and enters the heat exchange and purification center 6 at the bottom of the equipment through the outlet connecting pipe 12 and the sealing connecting component 7;

[0080] After entering the heat exchange and purification center 6, the hot insulating oil first flows through a composite purification system consisting of a coalescing layer 605 and an adsorption layer 604. The coalescing layer 605 is responsible for merging tiny water droplets suspended in the oil into larger droplets and filtering solid impurities. The adsorption layer 604 is responsible for adsorbing trace amounts of dissolved water, achieving deep purification of the insulating oil. After purification, the insulating oil transfers its heat to the outer shell and side wall heat dissipation plates 602 within the central housing 601, and finally dissipates it into the surrounding environment. The cooled and purified insulating oil is then drawn back into the high-voltage transformer body 1 through another sealed connection component 7, ready to enter the next cycle.

[0081] The entire operation is under closed-loop intelligent monitoring.

[0082] The fiber optic temperature sensor 905 and acoustic sensor 1006, placed in key locations, collect real-time status data such as temperature and vibration of the equipment.

[0083] Based on this data, the intelligent control system performs adaptive cooling: when the equipment load is high and the heat generation is large, it automatically increases the speed of the circulating pump to enhance the cooling effect; when the load is low, it reduces the speed to save energy. At the same time, the system performs predictive maintenance by analyzing the historical trends of sensor data: it provides early warning of potential faults in the circulating pump or the trend of insulation degradation, realizing the transformation from "fault maintenance" to "condition maintenance".
