Abstract

The invention belongs to the technical field of high polymer material, specifically relates to a material of a noise-reducing and radiating shell of a transformer. The shell material comprises the following raw materials by weight parts: 30-40 parts of polyurethane resin, 15-26 parts of methyl vinyl silicone rubber, 20-35 parts of carbon fiber, 10-20 parts of aluminium oxide,7-12 parts of kieselguhr, 2-8 parts of silicone oil, 0.5-1.5 parts of antioxidant,2-5 parts of 2,5-dimethyl-2,5-dual (tert butyl peroxy)hexane. The noise-reducing and radiating shell material of the transformer provided in the invention has lightweight, high hardness, shock resistance, wearing resistance, ageing resistance and good effects of sound absorption and radiating.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a noise-reducing and heat-dissipating shell material for a transformer. Background technique [0002] With the needs of urban construction, more and more substations are built in the urban area. When the transformer is working, it often produces relatively large noise due to the vibration of the iron core and coil, which interferes and affects people's life, work and study, and affects The human body is healthy, and the transformer and reactor rooms are designed in a closed manner without ventilation windows or exhaust fans. In high temperature and high load seasons, the temperature of the transformer and reactor rooms can reach above 60°C, which affects the life and safe operation of the transformer. , it is of great significance to develop a transformer noise reduction and heat dissipation shell material. [0003] Chinese patent CN105153675A discloses a s...
