Abstract

The invention discloses a high-temperature-resistant sound insulation board which comprises a keel frame, a carbon steel plate, a first aluminum silicate fiber plate, a second aluminum silicate fiber plate, aluminum foil and a micro-perforated plate, and the carbon steel plate, the first aluminum silicate fiber plate, the second aluminum silicate fiber plate, the aluminum foil and the micro-perforated plate sequentially penetrate through the keel frame, a firstcavity is formed between the the first aluminum silicate fiber plate and the second aluminum silicate fiber plate, and a second cavity is formed between the aluminum foil and the micro-perforated plate. The obtained high-temperature-resistant sound insulation board is of a double-resonance coupling structure, the low-frequency sound absorption and sound insulation effects are improved through coupling of formants by means of resistive and resonance materials, so that the purpose of expanding the sound absorption and sound insulation frequency band is achieved, and meanwhile the high-temperature-resistant performance of the sound insulation board is improved by selecting proper materials. The high temperature resistance and the sound insulation performance are further improved through parameter design of the sound insulation plate and used materials. The sound insulation board is simple in structure, is made of common materials, and is convenient for large-scale production and application in converter stations.

Description

technical field [0001] The invention relates to the field of sound insulation, in particular to a high temperature resistant sound insulation board. Background technique [0002] With the increasing demand for electricity, my country's UHV projects are under rapid construction. The UHV DC converter station is the core of the UHV DC project to realize the mutual conversion between AC and DC. Its operation reliability directly affects the safety of personnel, equipment and the power grid. Stable operation. When some equipment in the converter station is short-circuited or overheated, deflagration will occur in severe cases, which is directly related to the safety of personnel and a large number of equipment. The sealing of the converter transformer and valve hall is the key to fire prevention and self-rescue. Therefore, it is necessary to ensure the sealing The components of the blocking component material system can reliably serve for no less than 20 hours under high-temperat...
