Air cooler heat preservation house for convertor stations in severe cold areas

Abstract

The invention discloses an air cooler heat preservation house for convertor stations in severe cold areas. The air cooler heat preservation house comprises a plurality of stand columns arranged aroundan air cooler. Supporting cross beams are erected between the tops of the stand columns. The stand columns and the supporting cross beams form a main frame body covering the air cooler. Heat preservation wall bodies are arranged on the main frame body, and heat preservation rolling doors capable of opening and closing are mounted on the main frame body. The galvanized steel rolling doors are correspondingly arranged between the stand columns of the main frame body. A plurality of louvers capable of opening and closing are arranged above the galvanized steel rolling doors. A double-slope roofis arranged above the supporting cross beams. The double-slope roof is provided with a plurality of roof stainless steel rolling doors. The enclosure structure can be opened and closed, and electric and manual operation modes are achieved simultaneously. Normal circulation of air cooler heat exchange media during debugging and maintenance of a convertor valve is guaranteed, and orderly air flow ofsurrounding air of the air cooler during normal operation of the air cooler is guaranteed. Normal heat dissipation can be carried out, heart exchange requirements can be met, and operation is stableand reliable.

Description

technical field [0001] The invention relates to the field of electric power engineering, in particular to an air cooler insulation chamber used for a converter station in a severe cold area. Background technique [0002] The converter station refers to the station established in the high-voltage direct current transmission system to complete the conversion of alternating current to direct current or direct current to alternating current, and to meet the safety, stability and power quality requirements of the power system. [0003] The air cooler uses ambient air as the cooling medium, and the fan drives the outdoor air flow to the outer surface of the heat exchange fin tube bundle to cool or condense the high-temperature process fluid in the fin tube, referred to as "air cooler". The air cooler is mainly composed of heat exchange tube bundles, fans, motors, air ducts, bellows, frames, and operation and maintenance platforms. [0004] In areas where water resources are scarc...

AI Technical Summary

Problems solved by technology

[0007] 1) The overall sealing and heat preservation effect of the simple heat preservation shed is poor, and it has no ability to resist wind and sand;

[0008] 2) The roof of the steel mesh needs to be manually laid with canvas insulation materials, and multiple cycles are required during operation, which consumes materials and manpower;

[0009] 3) The simple thermal insulation shed is not organically combined with the layout of the air-cooling equipment, and occupies a large area
