Description

Technical Field

[0001] This invention relates to the field of transformer control technology, specifically to a transformer electromagnetic balance control device. Background Technology

[0002] A transformer is a device that uses the principle of electromagnetic induction to change alternating current voltage. Its main components are a primary coil, a secondary coil, and an iron core or magnetic core. The transformer electromagnetic balance control device is an energy-saving device applied in high-voltage power systems. It is primarily based on the principle of electromagnetic balance, optimizing the utilization of electrical energy through specific winding structures and electromagnetic interactions to achieve energy saving and improved power quality. In the prior art, Chinese invention patent CN119446715A discloses an electromagnetic balance winding high-voltage energy-saving device, including a housing, energy-saving components, and mounting components. This invention uses mounting components installed inside the housing to provide support for the energy-saving components, ensuring that each component is in a stable working position. Stable installation helps reduce electromagnetic interference caused by shaking or displacement between components, achieving better energy-saving effects. The oil temperature controller monitors the oil temperature inside the transformer tank. When the oil temperature is too high, it may affect the performance of the electrical equipment inside the device, leading to increased power loss and potentially transformer burnout due to current overload. Monitoring by the oil temperature controller allows for timely measures to control the oil temperature, preventing a decrease in the device's energy-saving efficiency due to excessive oil temperature and eliminating the risk of burnout due to current overload, ensuring the device operates at high efficiency and achieving both safety and energy saving. In the aforementioned technologies, the electromagnetic balance control device is usually installed directly near the transformer or in the distribution cabinet. Since the transformer or distribution cabinet will generate a certain amount of vibration during operation, the vibration is transmitted to the electromagnetic balance control device. The power electronic unit, winding and capacitor compensation module inside the electromagnetic balance control device will also generate continuous vibration. Large-amplitude vibration will directly affect the operational safety and energy efficiency of the electromagnetic balance control device. Summary of the Invention

The friction reduces the vibration amplitude of the first mounting plate, thereby achieving the purpose of vibration reduction of the electromagnetic balance control device body and ensuring the safe operation and energy efficiency of the electromagnetic balance control device. 2. The electromagnetic balance control device body is cooled and dissipated through heat dissipation holes. During the long-term heat dissipation process, dust will adhere to the surface of the heat dissipation holes. The dust will block the heat dissipation holes and affect the heat dissipation effect of the electromagnetic balance control device body. The cleaning rod can be set to clean the heat dissipation holes. When the first mounting plate vibrates relative to the first fixed plate, the squeezing block moves up and down inside the groove. During the movement, the third air storage bladder is squeezed by the cooperation of the oblique cut surface. The gas inside the third air storage bladder is discharged into the fourth air bladder through the second exhaust pipe. The fourth air bladder expands and pushes the rack upward. Through the cooperation of the rotating shaft, the cleaning rod swings to clean the heat dissipation holes. Attached Figure Description
