Abstract

The invention relates to a sound absorption and insulation integrated device for low-frequency noise suppression of a power transformer. The device comprises a basic sound absorber and a metal partition plate. A closed cavity is formed between the basic sound absorber and the metal partition plate, and the basic sound absorber comprises foam metal and a copper film attached to the surface of the foam metal. The beneficial effects of the device are that: the sound absorption and insulation integrated device for low-frequency noise suppression of the power transformer is novel in structure, skillful in design. A mute device unit is formed by a plurality of assembly combination structures. The device comprises a main body sound absorption material, a resonance sound absorption material, a variable cavity and a sound insulation material. Through repeated research and testing, the device has targeted sound absorption and insulation effects on low-frequency noise of a power transformer, it is guaranteed that the basic mute device unit has the basic sound absorption and insulation effects and has the adjusting potential, and good adaptability and adjustability are achieved.

Description

technical field [0001] The application belongs to the field of electric equipment, and in particular relates to an integrated sound-absorbing and insulating device for suppressing low-frequency noise of a power transformer. Background technique [0002] Power transformers are one of the main pieces of equipment in power plants and substations. The role of the transformer is multifaceted. It can not only increase the voltage to realize long-distance transmission of electric energy, but also reduce the voltage to meet the needs of customers with different voltage levels. [0003] The transformer noise in the substation is the sum of the noise generated by the transformer body and the cooling system. [0004] With the improvement of people's awareness of environmental protection and the restrictions on various types of noise by environmental protection departments, especially due to the continuous expansion of cities and the needs of urban power grid transformation, some subst...
