Box-in device with both sound insulation module and fire-fighting module

Abstract

The invention relates to a Box-in device with both a sound insulation module and a fire-fighting module. The Box-in device comprises a side surface fire-fighting module and a top noise reduction module; the side surface fire-fighting module comprises four fire-fighting pipeline modules which are embedded into the two sides, close to a converter transformer, of a firewall in a symmetrical manner; the four fire-fighting pipeline modules are an active oil discharge pipeline module, a water spraying pipeline module, a foam pipeline module and a compressed air foam pipeline module respectively; thetop noise reduction module is a sound absorption and insulation board arranged on the top; the sound absorption and insulation board is divided into an explosion venting and falling sound insulationboard and a fixed sound insulation board according to areas; the explosion venting and falling sound insulation board is made of a high-temperature hot-melt material and can automatically fall off when a fire breaks out; and the fixed sound insulation board adopts a filled sound insulation board, and a supporting steel structure is installed below the fixed sound insulation board for supporting. For the Box-in device, the noise reduction and sound insulation boards on the top of the Box-in device and fire-fighting pipelines arranged on the side surface of the converter transformer are subjected to modular integration for synergistic effect, namely, excellent sound insulation performance of the Box-in device and the safety of operation of the converter transformer are both ensured.

Description

technical field [0001] The invention relates to the technical field of electromagnetic environment and fire safety for power transmission and transformation equipment in the electric power industry, in particular to a Box-in device with both a sound insulation module and a fire protection module. Background technique [0002] The converter station is the most important node of the DC transmission line, and ensuring the safe and stable operation of the converter station is the key to DC transmission. The converter transformer is one of the most important equipment in the converter station. As the main noise source in the converter station, the converter transformer needs to adopt corresponding noise reduction schemes to reduce the factory boundary noise of the converter station, so as to realize an environment-friendly power grid . The sound insulation cover (Box-in) is widely used in the noise reduction engineering of current converters due to its obvious noise reduction ef...
