Financial News on June 4, 2025, according to information from the State Intellectual Property Office, Jiangsu Fengshen Air Conditioning Group Co., Ltd. and Fengshen Air Ecological Technology Engineering (Shanghai) Co., Ltd. applied for a patent called "A design method for a soundproof enclosure to eliminate low-frequency noise of UHV transformers", with a publication number of CN120089504A and an application date of March 2025. This invention belongs to the field of noise reduction technology for power equipment. The main body of the soundproof enclosure designed by it is a four-layer composite structure, which is composed of a metal shell, a core barrier sound insulation layer, a high-performance sound absorption layer and a soundproof layer from the outside to the inside. The soundproof layer is composed of multiple soundproofing components distributed in an array, and a shock-absorbing pad is provided at the lower end of the main body of the soundproof enclosure. This design significantly reduces low-frequency noise through a multi-layer composite structure, uses automated cleaning to maintain efficient ventilation and heat dissipation, and uses an optimized silent exhaust system to ensure low-noise operation. It will comprehensively improve the noise reduction effect and operating efficiency of UHV transformers and create a better environment for the stable operation of UHV transformers.
