Abstract
This invention relates to the field of transformer technology and discloses a high-performance transformer based on power engineering, including a transformer box, a top cover, and an external controller. The top cover is fixedly connected to the top of the transformer box. A conveying assembly for oil supply and replenishment is provided on the top side wall of the transformer box. Through the coordinated operation of the exhaust pipe, sealing column, venting groove, float, slide rod, piston plate, and spring in the exhaust assembly, the air accumulated in the guide pipe and exhaust pipe is automatically discharged in the initial stage of oil replenishment. After the oil enters, the float rises with the oil level and automatically blocks the venting groove, realizing exhaust only and no oil spraying. The elastic force generated by the elastic deformation of the spring is greater than the hydraulic force of the insulating oil acting on the piston plate. Under normal conditions, the piston plate blocks the oil outlet. Only after the air is completely exhausted and the oil pressure reaches the set value will it move down to open the oil circuit, realizing the timing control of exhaust first and then oil supply.
