Description

Technical Field

[0001] This invention relates to the field of transformer protection technology, specifically to a transformer with intelligent protection functions. Background Technology

[0002] Transformer lightning protection equipment mainly includes surge arresters (such as valve-type and zinc oxide surge arresters) and grounding devices. Their core function is to limit lightning overvoltages through nonlinear characteristics, rapidly diverting lightning current to the ground and protecting the transformer insulation from breakdown. Simultaneously, surge arresters can defend against switching overvoltages, reducing equipment failures and power outage losses. In some scenarios, lightning rods / surge strips are required for active lightning attraction to prevent direct strikes to the transformer, while the grounding system ensures a low-impedance discharge path (grounding resistance ≤10Ω) to prevent ground potential backflash. Installing surge arresters on both high and low voltage sides provides comprehensive protection against lightning surge intrusion and forward / reverse transformation overvoltages.

[0003] Transformer lightning protection uses surge arresters instead of lightning rods. Lightning rods actively attract direct lightning strikes through tip discharge, directly conducting the lightning current to the ground. The protection range is the external space of the building or equipment, but it will generate a strong electromagnetic field, which may induce overvoltages that can intrude into adjacent equipment. Surge arresters are connected in parallel on the transformer's incoming line side. They achieve voltage limiting (rapid conduction when lightning waves intrude, limiting the overvoltage to the equipment's tolerance range) and current dissipation (conducting the lightning current to the grounding grid, with a response time as fast as 20ns) through nonlinear resistance characteristics (such as zinc oxide varistors). The core requirement of transformer lightning protection is to resist intrusion waves rather than direct lightning strikes. The real threat is the lightning-induced overvoltage waves that intrude along the transmission line. Surge arresters can directly block line overvoltages, while lightning rods are ineffective against this.

[0004] Chinese patent CN111091963A discloses an outdoor lightning protection transformer. This outdoor lightning protection transformer can automatically use and store its lightning protection structure, reducing wind bending damage caused by external storage. At the same time, it can greatly reduce the impact of wind and rain during use, thus achieving the protection of the lightning protection structure.

[0005] Chinese patent CN119153217B discloses a transformer with a lightning protection structure. By setting up a drive mechanism and a protection component, the drive mechanism works when a raindrop sensor detects raindrops, and the protective cover in the protection component unfolds accordingly. At the same time, the lightning rod inside the protective cover slowly rotates out of the protection component until it is vertically upward. Then, the locking component limits and locks the large gear in the drive mechanism, thereby increasing the stability of the lightning rod. When the raindrop sensor does not detect raindrops, the lightning rod is stored in the protection component, which provides good protection for the lightning rod and increases its service life.

[0006] While lightning rods, as described above and similar existing technologies, can draw lightning to the ground, their protection range is limited, especially in terms of protection against induced lightning and lightning surges intruding along power lines. When the lightning current is large, poor grounding of the lightning rod or excessively high grounding resistance (>4Ω) can lead to an increase in residual voltage. Some of the lightning current may be diverted to the transformer, causing insulation breakdown. In addition, lightning rods may cause a "backflashover" phenomenon—high voltage is generated on the grounding device when the lightning current is discharged, which can reverse-damage the equipment. To protect the surge arrester from sun and rain, sun protection devices often use a sealed enclosure structure, but this seriously hinders heat dissipation. For every 10°C increase in temperature, the aging rate of the varistors doubles. Long-term high-temperature operation will significantly shorten the life of the surge arrester. Heat accumulation in the sealed environment leads to a continuous increase in internal temperature, accelerating the aging of the varistor material, reducing current carrying capacity and response speed, and reducing the overall reliability and lifespan of the transformer lightning protection system.

[0007] Therefore, the present invention provides a transformer with intelligent protection function that uses surge arresters for protection, provides real-time protection for surge arresters, and prevents surge arresters from aging. Summary of the Invention

[0008] To address the shortcomings of existing technologies in protecting against induced lightning and lightning surges intruding along power lines, as well as the deterioration of surge arrester performance due to high temperatures, a transformer with intelligent protection functions has been designed.

[0009] The technical solution adopted by this invention to solve its technical problem is as follows: a transformer with intelligent protection function, including a transformer body and a crossbar set on its top, a shock-absorbing part rotatably connected to the top of the crossbar, a surge arrester fixed inside the shock-absorbing part, an isolating component set on the top of the shock-absorbing part, a top plate rotatably connected to the top of the surge arrester, and a power part set at the bottom of the shock-absorbing part; the shock-absorbing part includes a longitudinal damper fixed to the top of the bottom wall of the crossbar and a transverse damper fixed to the outside of the surge arrester, which offsets the impact received by the surge arrester; the isolating component can block light from directly hitting the surge arrester, and it works with the top plate to convert the impact force received by the surge arrester in windy weather. It can exchange gas around the surge arrester and outside the isolating component by relying on wind power or the power part and the through-holes opened in itself. When the surge arrester is impacted, the cooperation between the isolating component and the shock-absorbing part accelerates gas exchange by changing the volume of the isolating component.

[0010] Furthermore, the damping unit also includes a base, which is fixed to the top of the longitudinal damper, the surge arrester is fixed to the inside of the base, the fixed end of the transverse damper is fixed to the inner wall of the base, and the output end of the transverse damper is fixed inside the base.

[0011] Furthermore, a bracket is rotatably connected to the top of the crossbar, and an arc-shaped plate is fixed to the top of the top plate.

[0012] Furthermore, the bottom of the isolation element is fixed to the top of the bracket, and the top of the isolation element is fixed to the bottom of the top plate.

[0013] Furthermore, the top of the bracket is rotatably connected to a support section, which is configured in two groups. Each group of support sections is arranged in a staggered ring array around the surge arrester as the axis. The distance between one group of support sections and the surge arrester is smaller than the distance between the other group of surge arresters.

[0014] Furthermore, each set of support components includes a low rod rotatably connected to the top of the bracket and a high rod rotatably connected to the bottom of the top plate. The ends of the low rod and the high rod that are close to each other are rotatably connected. The distance between the ends of the low rod and the high rod that are close to each other and the surge arrester is less than the distance between the other ends of the low rod and the high rod and the surge arrester. The isolator is fixed to the side of the low rod and the high rod away from the surge arrester.

[0015] Furthermore, the through-hole includes a tapered hole and a round hole, with the tapered hole extending through the outer side of the bottom end of the separator and the round hole extending through the outer side of the top end of the separator.

[0016] Furthermore, two crossbars are snapped onto the outside of the crossbar, and the bottom of the crossbar is fixed with two ends fixed to the outside of the utility pole. The transformer body is fixed to the inside of the utility pole through connecting parts. The transformer body is located at the bottom of the crossbar, and the bottom of the transformer is fixed with a distribution box through connecting parts.

[0017] Furthermore, the power unit includes a motor, which is fixed to the bottom of the top wall of the crossbar. A bevel gear is rotatably connected inside one side of the crossbar, and another bevel gear is provided at the bottom of the bracket. The two bevel gears mesh, and one of the bevel gears is fixedly connected to the output end of the motor. The two adjacent bevel gears are connected by a transmission component.

[0018] Furthermore, the transmission component is configured as a combination of two sprockets and a chain, or other devices capable of transmitting power.

[0019] The beneficial effects of this invention are: (1) The transformer with intelligent protection function described in this invention adopts the design of shock absorber and isolation component. The longitudinal damper is fixed at the bottom of the crossbar, and the transverse damper surrounds the outside of the surge arrester. The dual structure works together to absorb the impact force of lightning strikes. When the surge arrester moves longitudinally, it pushes the top plate to squeeze the isolation component, which reduces the volume of the space formed by the isolation component and the base, increases the internal air pressure and discharges high-temperature gas. During the reset process of the surge arrester, the volume of the space expands and generates negative pressure, actively drawing in external cold air and accelerating gas exchange and heat dissipation. At the same time, the high and low bar linkage design of the support part directionally adjusts the deformation amplitude of the isolation component and enhances the efficiency of volume change.

[0020] (2) The transformer with intelligent protection function described in this invention captures wind energy and converts it into rotational mechanical energy, driving the top plate to rotate the isolator to avoid strong winds blowing directly; the surface of the isolator is made of wear-resistant material to block ultraviolet rays, and the conical hole with the small opening facing inward is designed to form a low-pressure area by utilizing the Venturi effect to draw in external gas, and the round hole is located at the top to discharge the internal hot airflow by centrifugal force; when rotating, the internal gas is subjected to centrifugal force to surge towards the side wall, forming a spiral vortex to accelerate the airflow through the through hole to achieve zero-energy passive heat dissipation and greatly reduce the risk of aging of the surge arrester.

[0021] (3) The transformer with intelligent protection function described in this invention has a temperature sensor embedded inside the top plate to monitor the temperature of the surge arrester in real time; when the temperature is high and there is no wind, the distribution box processor starts the motor and drives the bracket to rotate through the bevel gear set and chain transmission component; the linkage support drives the isolation component to force ventilation, simulating the gas circulation under natural wind; the multi-mode adaptive design takes into account energy saving and efficiency: when the wind is sufficient, it relies on the arc plate for passive drive, and when the environment is abnormal, the motor actively intervenes to ensure heat dissipation stability.

[0022] (4) The transformer with intelligent protection function described in this invention consists of two sets of ring-shaped staggered support parts composed of low rods and high rods hinged together. When the surge arrester is displaced, the top plate squeezes the high rod, and the linkage of the low rod causes the connection point to move towards the surge arrester side, directionally compressing the volume of the isolator. When reset, the volume expands in the opposite direction to draw in gas. The staggered layout increases the windward area and enhances the wind power conversion efficiency. The non-equidistant design of the high and low rods and the surge arrester (one set close / one set far) optimizes the deformation accuracy and realizes the linear response of impact force-volume change.

[0023] (5) The transformer with intelligent protection function described in this invention integrates shock absorption, ventilation and temperature control functions in structure. The dual dampers absorb the impact, and the through hole design of the isolation component applies fluid mechanics to improve the heat dissipation efficiency by 40%+. The deformation control of the support part realizes the active conversion of impact energy to mechanical energy. The intelligent temperature control system dynamically switches between natural / forced ventilation modes through sensor feedback to adapt to extreme environments such as thunderstorms, high temperatures and no wind. The whole system uses mechanical innovation to reduce electronic dependence, extend the life of the surge arrester and improve the reliability of the transformer in all scenarios.

[0027] To make the technical means, technical features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0028] Example 1: As Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 8 , Figure 9 , Figure 11As shown, the transformer with intelligent protection function of the present invention includes a transformer body 1 and a crossbar 4 disposed on its top. A shock-absorbing part 5 is rotatably connected to the top of the crossbar 4. A surge arrester 6 is fixed inside the shock-absorbing part 5. An isolator 8 is disposed on the top of the shock-absorbing part 5. A top plate 7 is rotatably connected to the top of the surge arrester 6. The shock-absorbing part 5 includes a longitudinal damper 51 fixed to the top of the bottom wall of the crossbar 4 and a transverse damper 53 fixed to the outside of the surge arrester 6 to offset the impact received by the surge arrester 6. The isolator 8 can block light. The line-direct surge arrester 6, together with the top plate 7, converts the impact force received by the surge arrester 6 in windy weather. Relying on wind power or the power unit and the through holes opened on its own, it can exchange the gas around the surge arrester 6 and the outside of the isolator 8. When the surge arrester 6 is impacted, the cooperation between the isolator 8 and the shock-absorbing part 5 accelerates the gas exchange by changing the volume of the isolator 8. The top of the crossbar 4 is rotatably connected to the bracket 84. The top of the top plate 7 is fixed with an arc plate 71. The bottom of the isolator 8 is fixed to the top of the bracket 84, and the top of the isolator 8 is fixed to the bottom of the top plate 7.

[0029] In this embodiment, during windy weather, the arc plate 71 converts the kinetic energy carried by the wind into the mechanical energy of the rotation of the top plate 7, thereby causing the top plate 7 to drive the isolator 8 to rotate, preventing the strong wind from blowing directly on the surge arrester 6 and reducing the risk of damage to the surge arrester 6 due to excessive wind. The surface of the isolator 8 is treated with wear-resistant material, which can not only effectively isolate strong winds, but also maintain good rotational flexibility during long-term use, which not only improves the service life of the surge arrester 6, but also enhances the stability and safety of the entire transformer.

[0030] Specifically, the through hole includes a tapered hole 81 and a round hole 83. The tapered hole 81 is opened through the outer side of the bottom end of the spacer 8, and the round hole 83 is opened through the outer side of the top end of the spacer 8.

[0031] During thunderstorms, when the isolator 8 rotates under the influence of wind, the gas inside it moves towards the outer wall due to centrifugal force. The gas is squeezed outward by centrifugal force and is discharged outward through the circular hole 83. The design of the conical hole 81 utilizes the "Venturi effect". The small opening of the conical hole 81 faces inward, which limits the amount of gas outflow. The large opening of the conical hole 81 faces outward, connecting with the external environment. The low-pressure area attracts external gas to flow in, and the centrifugal force causes the internal gas to rush outward. A low-pressure area is formed in the central region of the cylinder. Driven by the pressure difference, the external gas rushes into the interior from the large opening end of the lower conical through hole, completing the gas replenishment. The rotation of the isolator 8 will form a spiral vortex inside, promoting the movement of gas towards the circular hole 83 and the conical hole 81. After the external gas enters through the conical hole, it participates in the internal circulation due to the influence of rotational inertia, forming a continuous exchange. Example 2: Figure 1 , Figure 2 , Figures 4-11As shown, the present invention discloses a transformer with intelligent protection function, comprising a transformer body 1 and a crossbar 4 disposed on its top. A shock-absorbing part 5 is rotatably connected to the top of the crossbar 4. A surge arrester 6 is fixed inside the shock-absorbing part 5. An isolator 8 is disposed on the top of the shock-absorbing part 5. A top plate 7 is rotatably connected to the top of the surge arrester 6. The shock-absorbing part 5 includes a longitudinal damper 51 fixed to the top of the bottom wall of the crossbar 4 and a transverse damper 53 fixed to the outside of the surge arrester 6, which counteracts the impact received by the surge arrester 6. The isolator 8 blocks direct sunlight from reaching the surge arrester 6. It works with the top plate 7 to convert the impact force received by the surge arrester 6 in windy weather. It can exchange gas around the surge arrester 6 and outside the isolator 8 by relying on wind power or a power unit and its own through-hole. When the surge arrester 6 is impacted, the cooperation between the isolator 8 and the shock-absorbing part 5 accelerates gas exchange by changing the volume of the isolator 8. A bracket 84 is rotatably connected to the top of the crossbar 4, and an arc-shaped plate 71 is fixed to the top of the top plate 7. In this embodiment, when the surge arrester 6 is subjected to an impact, such as a lightning strike, the longitudinal damper 51 and the transverse damper 53 work together to absorb and disperse the impact force, protecting the surge arrester 6 and its connected electrical equipment from damage. When the surge arrester 6 moves longitudinally, it will cause the top plate 7 to squeeze the isolator 8, increasing the pressure in the space formed by the isolator 8, the top plate 7, and the base 52, thus expelling the gas. After the lightning strike, during the process of the surge arrester 6 returning to its original position, the pressure formed by the isolator 8, the top plate 7, and the base 52 decreases, drawing in outside air. Combined with the rotation of the isolator 8 for ventilation, this can accelerate the gas exchange around the surge arrester 6, effectively dissipate heat, and ensure that the surge arrester 6 always remains in the best protection state.

[0032] Specifically, the damping unit 5 also includes a base 52, which is fixed to the top of the longitudinal damper 51. The surge arrester 6 is fixed to the inside of the base 52. The fixed end of the transverse damper 53 is fixed to the inner wall of the base 52, and the output end of the transverse damper 53 is fixed inside the base 52. The top of the bracket 84 is rotatably connected to a support 82, which is configured in two groups. Each group of support 82 is arranged in a staggered ring array around the surge arrester 6. The distance between one group of support 82 and the surge arrester 6 is smaller than that between the other group. The distance between surge arresters 6 and surge arresters 6, each set of support parts 82 includes a low rod 821 rotatably connected to the top of the bracket 84 and a high rod 822 rotatably connected to the bottom of the top plate 7, and the ends of the low rod 821 and the high rod 822 that are close to each other are rotatably connected, and the distance between the ends of the low rod 821 and the high rod 822 and the surge arrester 6 is less than the distance between the other ends of the low rod 821 and the high rod 822 and the surge arrester 6. The isolator 8 is fixed to one side of the low rod 821 and the high rod 822 and the surge arrester 6.

[0033] In this embodiment, when the surge arrester 6 moves longitudinally, it causes the top plate 7 to press against the isolator 8. The top plate 7 presses against the high rod 822, and the high rod 822 causes the low rod 821 to rotate, simultaneously moving the connection between the high rod 822 and the low rod 821 closer to the surge arrester 6. The high rod 822 and the low rod 821 cause the isolator 8 to deform in a specific direction, reducing the space formed by the isolator 8, the top plate 7, and the base 52, increasing the internal pressure and expelling gas. During the process of the surge arrester 6 returning to its original position after a lightning strike, the top plate 7 pulls the high rod 822... As rod 822 drives the lower rod 821 to rotate, the connection between the higher rod 822 and the lower rod 821 moves away from the arrester 6. The higher rod 822 and the lower rod 821 cause the isolating member 8 to deform in a specific direction, which increases the space formed by the isolating member 8, the top plate 7, and the base 52, reduces the internal pressure, and allows the gas to be discharged. The rotation of the isolating member 8 can accelerate the gas exchange around the arrester 6. In addition, the staggered design of the support part 82 increases the contact area between the isolating member 8 and the wind, which can help the arc plate 71 and the top plate 7 to convert the wind impact.

[0034] Example 3: Based on Example 1 or Example 2, such as... Figure 3 As shown, a power unit is provided at the bottom of the shock-absorbing part 5. The power unit includes a motor 9, which is fixed to the bottom of the top wall of the crossbar 4. A bevel gear 11 is rotatably connected inside one side of the crossbar 4. Another bevel gear 11 is provided at the bottom of the bracket 84. The two bevel gears 11 mesh. One of the bevel gears 11 is fixedly connected to the output end of the motor 9. The two adjacent bevel gears 11 are connected by a transmission component 10. The transmission component 10 is set as a combination of two sprockets and a chain or other devices that can realize power transmission.

[0035] In this embodiment, a temperature sensor can be installed inside the top plate 7. When the internal temperature is too high, the processor inside the distribution box 2 controls the motor 9 to rotate. The motor 9 drives the sprocket and bevel gear 11 on the outer side of its output end to rotate. The sprocket drives the other two bevel gears 11 and the bevel gear 11 on the outer side of the output end of the motor 9 to rotate synchronously through the chain drive. This drives the bevel gear 11 at the bottom of the bracket 84 to rotate. The bevel gear 11 drives the isolation piece 8 and the top plate 7 to rotate through the bracket 84 and the support part 82, thereby accelerating the gas exchange process or assisting in gas exchange and cooling in hot and windless or low wind conditions.

[0036] Working principle: In windy weather, the arc plate 71 converts the kinetic energy carried by the wind into the mechanical energy of the rotation of the top plate 7. In thunderstorm weather, under the action of wind, when the isolator 8 rotates, the gas is squeezed outward by centrifugal force. The internal gas is discharged outward through the circular hole 83. Centrifugal force causes the internal gas to surge outward. The external gas is driven by the pressure difference and surges into the interior from the large opening end of the lower conical through hole to complete the gas replenishment. The rotation of the isolator 8 will form a spiral vortex inside, which promotes the gas to move towards the circular hole 83 and the conical hole 81. After the external gas enters through the conical hole, it participates in the internal circulation due to the influence of rotational inertia, forming a continuous exchange. When the surge arrester 6 is impacted, such as when struck by lightning, the longitudinal damper 51 and the transverse damper 53 work together to absorb and disperse the impact force.

[0037] Before implementing any of the above embodiments, it should be noted that: the surge arrester 6 is installed close to the protected equipment (such as the high and low voltage sides of the transformer body 1), and its grounding terminal is connected to the equipment casing and neutral point (in the case of star connection) through a short straight conductor to a unified grounding device; the three-phase transformer body 1 adopts a star (with neutral point grounding) or delta connection according to system requirements; the distribution box 2 follows a three-phase five-wire system (L1 / L2 / L3+N+PE), and the PE line runs through all equipment casings; the surge arrester in the power supply line is connected across the phase line / neutral line and the PE line to form an equipotential bonding protection system.

[0038] Grounding principle for surge arrester 6: The grounding wire of surge arrester 6 must be short and straight (length ≤ 25cm), and share the same grounding wire (cross-sectional area ≥ 25mm² copper wire) with the equipment casing and the neutral point of transformer body 1, in order to reduce residual voltage.

[0039] Installation location: The high-voltage side should be close to the input terminal of transformer body 1, and the low-voltage side needs to be equipped with a separate anti-reverse voltage conversion device.

[0040] Three-phase transformer connection method: Star (Y) connection: The neutral point is led out and grounded, which is suitable for systems that require neutral point grounding (such as TN-S) and provides a ground fault loop.

[0041] Triangle (Δ) connection: No neutral point, suitable for high-voltage power transmission.

[0042] Wiring specifications for distribution box 2: Three-phase five-wire system (L1 / L2 / L3+N+PE) is adopted. The PE wire is connected to the metal casing of all equipment. Outdoor distribution box 2 must be grounded by welding flat steel. The grounding resistance is ≤10Ω (below 100kVA) or ≤4Ω (above 100kVA).

[0043] Lightning protection for power supply lines: In the TN-S system, the surge protector bridging mode is: L-PE, N-PE (common mode) or LN (differential mode, for important equipment); the neutral line (N) and the protective line (PE) are connected at a single point in the main distribution panel to avoid stray currents.
