Description

Technical Field

[0001] This invention relates to the field of transformers, and in particular to a new energy transformer with self-leakage treatment. Background Technology

[0002] New energy transformers are core equipment in clean energy power generation systems such as wind and solar power, undertaking the critical tasks of voltage transformation and power transmission. Their operational stability directly affects the power generation efficiency and safety of new energy power plants. However, in practical applications, the transformer sealing structure is prone to aging and cracking due to long-term exposure to heat, oil corrosion, and mechanical vibration, leading to transformer oil leakage.

[0003] To address leakage caused by aging and cracking of the sealing ring, existing technologies generally adopt a passive maintenance model, relying on regular manual inspections and emergency response after an accident. The core process is "inspection discovery → leakage confirmation → temporary remediation → shutdown for maintenance," but this approach has significant limitations. Firstly, manual inspections detect leaks by visually checking oil levels, oil stains, or localized temperature measurements. However, the inspection cycle is typically daily or weekly, which is relatively long. Leaks may persist for hours or even days before being discovered, during which time continuous transformer oil leakage can lead to secondary faults such as decreased insulation performance and localized overheating.

[0004] In summary, the passive maintenance mode adopted in the existing technology for the problem of leakage caused by aging and cracking of the sealing ring relies on regular manual inspections. Due to the long inspection cycle, leakage may go undetected for a long time, leading to secondary failures. Summary of the Invention

[0005] This invention provides a new energy transformer with self-treatment of leakage, which can solve the problem of leakage caused by aging and cracking of sealing rings in the prior art. It relies on manual periodic inspection, and because the inspection cycle is long, leakage may go undetected for a long time, leading to secondary failures.

[0006] A new energy transformer with self-leakage control includes several bushings and sealing rings fixedly installed on the surface of the transformer body. A leakage control mechanism is installed inside the transformer body, and the leakage control mechanism includes: A liquid level sensor that is fixedly installed inside the transformer body; A base rod is fixedly installed on the surface of the transformer body. A rotating rod is rotatably connected inside the base rod. A rotating shaft is rotatably connected to the surface of the transformer body. An elastic band is fixedly connected between the rotating shaft and the rotating rod. The elastic band is slidably installed on the surface of the transformer body. A drive gear ring is rotatably mounted on the surface of the bushing. The drive gear ring is fixedly connected to the rotating shaft. Several drive gears that mesh with the drive gear ring are fixedly connected to the surface of the transformer body. A control component is provided between the drive gear ring, the liquid level sensor and the transformer body.

[0007] Optionally, the liquid level sensor is a fiber optic liquid level sensor or a capacitive liquid level sensor, and the liquid level sensor is fixedly installed on the top of the transformer body.

[0008] Optionally, the capacitive level sensor is inserted into the transformer oil.

[0009] Optionally, a rotating ring is fixedly connected to the end of the rotating rod. The rotating ring is rotatably disposed inside the transformer body. The cross-section of the rotating ring is T-shaped. A ring spring is fixedly connected between the rotating ring and the transformer body.

[0010] Optionally, one end of the annular spring is fixedly connected to the transformer body, and the other end of the annular spring is fixedly connected to a fixing ring. A fixing groove is formed on the surface of the rotating ring, and the fixing ring is adapted to the fixing groove.

[0011] Optionally, a support rod is fixedly connected to the surface of the transformer body, and a fixed rod is slidably connected inside the support rod. Limit grooves are formed on the surfaces of the base rod and the rotating shaft. The fixed rod is adapted to the limit grooves. A connecting spring is fixedly connected between the fixed rod and the support rod, and the connecting spring is sleeved on the surface of the fixed rod.

[0012] Optionally, a transmission assembly is provided between the plurality of drive gears, the transmission assembly including a transmission wheel fixedly disposed on the surface of the drive gear, and a transmission belt drivingly connecting adjacent transmission wheels.

[0013] Optionally, a shielding cover is fixedly connected to the surface of the transformer body, and the shielding cover covers the drive wheel and drive belt.

[0014] Optionally, a limit ring is threadedly connected to the end of the drive gear, and a sliding groove is provided inside the transformer body, which is adapted to the limit ring.

[0015] Optionally, the control components include a PLC controller, an alarm, and a motor fixedly mounted on the surface of the transformer body. The input terminal of the PLC controller is electrically connected to the liquid level sensor, the output terminal of the PLC controller is electrically connected to the controller and the motor, and the output terminal of the motor is fixedly connected to the drive gear.

[0016] This invention provides a new energy transformer with self-cleaning leakage control, including a liquid level sensor installed inside the transformer body. The liquid level sensor can sensitively detect changes in the liquid level inside the transformer body, thereby promptly detecting leakage. A base rod is installed on the surface of the transformer body, and a rotating rod with an elastic band wound around it is installed inside the base rod. A rotating shaft rotating around the bushing is located at the other end of the elastic band. As the rotating shaft rotates one revolution, it causes the elastic band to extend continuously, forming a ring on the bushing surface, separating the bushing from the external space. If leakage occurs due to aging and cracking of the sealing ring, the elastic band can limit the leaked transformer oil to concentrate between the elastic band and the sealing ring, preventing it from contacting other parts of the transformer body surface, effectively preventing secondary faults caused by leakage. Simultaneously, the sealing ring supporting the transformer oil will differ from other sealing rings, helping maintenance personnel quickly locate the cracked sealing ring. A control component is installed between the elastic band and the liquid level sensor. Changes in the liquid level sensor data can directly cause the elastic band to extend, dividing the space around the bushing, providing temporary remediation to prevent the spread of transformer oil and secondary faults.

[0019] The specific embodiments of the present invention will be described in detail below, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0020] like Figures 1 to 6 As shown in the figure, a new energy transformer with self-leakage treatment provided in this embodiment of the invention includes a plurality of bushings 2 fixedly disposed on the surface of the transformer body 1. It should be noted that the bushing 2 is fixedly connected to the transformer body 1 by a screw; A sealing ring 3 is fixedly installed between the transformer body 1 and the bushing 2. A leakage control mechanism is installed inside the transformer body 1. The leakage control mechanism includes: A liquid level sensor 41 is fixedly installed inside the transformer body 1; It should be noted that the liquid level sensor 41 is a device for monitoring, measuring and controlling the liquid position. It can sense changes in liquid level, convert the data into electrical signals, and realize automated control and safety protection. A base rod 42 is fixedly installed on the surface of the transformer body 1. A rotating rod 43 is rotatably connected inside the base rod 42. A rotating shaft 44 is rotatably connected to the surface of the transformer body 1. An elastic band 45 is fixedly connected between the rotating shaft 44 and the rotating rod 43. The elastic band 45 is wrapped around the surface of the rotating rod 43 and is slidably installed on the surface of the transformer body 1. The projection of the base rod 42 and the rotating shaft 44 toward the bushing 2 covers the sealing ring 3, and the height of the rotating shaft 44 is greater than the height of the sealing ring 3. A drive gear ring 46 is rotatably mounted on the surface of the bushing 2. The drive gear ring 46 is fixedly connected to the rotating shaft 44. Several drive gears 47 are fixedly connected to the surface of the transformer body 1. The drive gears 47 mesh with the drive gear ring 46. A control component is provided between the drive gear ring 46, the liquid level sensor 41 and the transformer body 1. The control component is used to correlate the signal change of the liquid level sensor 41 with the rotation of the drive gears 47. In summary, the new energy transformer with self-cleaning leakage protection provided by this embodiment of the invention includes a liquid level sensor 41 installed inside the transformer body 1. The liquid level sensor 41 can sensitively detect changes in the liquid level inside the transformer body 1, thereby promptly detecting leakage. Furthermore, a base rod 42 is installed on the surface of the transformer body 1, and a rotating rod 43 with an elastic band 45 wound around it is installed inside the base rod 42. A rotating shaft 44 is installed at the other end of the elastic band 45, rotating around the bushing 2. When the rotating shaft 44 rotates one revolution, it can cause the elastic band 45 to continuously extend, forming a loop on the surface of the bushing 2, separating the bushing 2 from the external space. If the current sealing ring 3 ages and cracks, causing leakage, the elastic band 45 can limit the leaked transformer oil to concentrate between the elastic band 45 and the sealing ring 3, preventing it from contacting other parts of the transformer body 1 surface. This can effectively prevent leakage from causing secondary faults. At the same time, the sealing ring 3 supporting the transformer oil will be different from the other sealing rings 3, which helps maintenance personnel to quickly locate the cracked sealing ring 3. Furthermore, a control component is set between the elastic band 45 and the liquid level sensor 41. The data change of the liquid level sensor 41 can directly drive the elastic band 45 to extend, dividing the space around the bushing 2, and temporarily remedying the situation to prevent the transformer oil from spreading and causing secondary faults. In some specific implementations, the liquid level sensor 41 is a fiber optic liquid level sensor or a capacitive liquid level sensor, and the liquid level sensor 41 is fixedly installed on the top of the transformer body; and the capacitive liquid level sensor is inserted into the transformer oil. In some specific implementations, a rotating ring 51 is fixedly connected to the end of the rotating rod 43. The rotating ring 51 is rotatably disposed inside the transformer body 1. The cross-section of the rotating ring 51 is T-shaped. A ring spring 52 is fixedly connected between the rotating ring 51 and the transformer body 1. When the annular spring 52 is in its initial state, it applies a stable tension to the rotating ring 51, keeping the rotating rod 43 in its initial position. At this time, the elastic band 45 is relatively loose and wrapped around the rotating rod 43. When the liquid level sensor 41 detects an abnormal liquid level, it drives the drive gear 47 to rotate through the control component. The drive gear 47 drives the drive gear ring 46 to rotate, which in turn causes the rotating shaft 44 to rotate. When the rotating shaft 44 rotates, it pulls the elastic band 45. At this time, the rotating ring 51 overcomes the tension of the annular spring 52 and rotates, allowing the elastic band 45 to unfold smoothly and form a loop around the sleeve 2. In a further embodiment, one end of the annular spring 52 is fixedly connected to the transformer body 1, and the other end of the annular spring 52 is fixedly connected to a fixing ring 53. A fixing groove 54 is formed on the surface of the rotating ring 51, and the fixing ring 53 is adapted to the fixing groove 54. One end of the annular spring 52 is connected to the fixing ring 53, and a fixing groove 54 is formed on the surface of the rotating ring 51, so that the fixing ring 53 can be directly inserted into the fixing groove 54, thereby facilitating the disassembly and assembly of the annular spring 52. In some specific implementations, a support rod 61 is fixedly connected to the surface of the transformer body 1, and a fixed rod 62 is slidably connected inside the support rod 61. Limiting grooves 63 are formed on the surfaces of the base rod 42 and the rotating shaft 44. The fixed rod 62 is adapted to the limiting groove 63. A connecting spring 64 is fixedly connected between the fixed rod 62 and the support rod 61, and the connecting spring 64 is sleeved on the surface of the fixed rod 62. In some specific implementations, a transmission assembly is provided between a plurality of the drive gears 47, the transmission assembly including a transmission wheel 71 fixedly disposed on the surface of the drive gear 47, and a transmission belt 72 is drivingly connected between adjacent transmission wheels 71. In a further embodiment, a shielding cover 73 is fixedly connected to the surface of the transformer body 1, and the shielding cover 73 covers the transmission wheel 71 and the transmission belt 72; the shielding cover 73 can prevent debris in the environment from directly contacting the transmission wheel 71 and the transmission belt 72, thereby ensuring smooth transmission between the transmission wheel 71 and the transmission belt 72. In some specific implementations, the end of the drive gear 47 is threadedly connected to a limiting ring 74, and the transformer body 1 has a sliding groove 75 inside, which is adapted to the limiting ring 74. In some specific implementations, the control components include a PLC controller, an alarm, and a motor fixedly mounted on the surface of the transformer body 1. The input terminal of the PLC controller is electrically connected to the liquid level sensor 41, and the output terminal of the PLC controller is electrically connected to the controller and the motor. The output terminal of the motor is fixedly connected to the drive gear 47. The motor is electrically connected to an external power supply. When the hydraulic sensor shows a data change, it can transmit the signal to the PLC controller, which can then drive the motor and activate the alarm. Thus, when leakage occurs in the transformer body 1, the liquid level sensor 41 can provide an alert through the PLC controller and the alarm, and drive the motor to achieve the wrapping of the elastic band 45. It should be noted that PLC controllers can store instructions for logic operations, sequential control, timing, counting, and arithmetic operations through programmable memory, and use digital or analog input / output modules to control various types of machinery or production processes; The alarm system includes an audible and visual alarm. When the liquid level sensor detects an abnormal liquid level, it immediately sends a signal to the PLC controller. Upon receiving the signal, the PLC controller not only drives the motor to unfold the elastic band but also triggers the audible and visual alarm. The alarm emits a loud sound and a clear light signal, quickly attracting the attention of those nearby and ensuring that relevant personnel are promptly aware of any leakage in the transformer, allowing for prompt action to prevent the fault from escalating and causing more serious consequences. Working principle of the invention: When the transformer body 1 leaks due to the cracking of the sealing ring 3, the liquid level sensor 41 sends a signal, the PLC controller issues an alarm, and the drive motor starts. The motor causes the drive gear 47 to rotate, which in turn causes the drive gear ring 46 to rotate, causing the rotating shaft 44 to slide on the surface of the transformer body 1. The elastic band 45 extends, and after the drive shaft slides to a certain position, it will drive the fixed rod 62 to move. The fixed rod 62 will move under the action of the connecting spring 64 and insert into the limiting groove 63 to limit the position of the rotating shaft 44. At this time, the limiting ring 74 contacts the end of the sliding groove 75, preventing the drive gear 47 from rotating again. After the rotating shaft 44 stops moving, the elastic band 45 forms a ring to limit the flow of transformer oil.

[0021] The above-disclosed embodiments are merely a few specific examples of the present invention. However, the embodiments of the present invention are not limited thereto, and any variations that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
