Fixed fireproof and anti-explosion plugging structure for protecting high-end valve hall of converter station

Abstract

The invention provides a fixed fireproof and anti-explosion plugging structure for protecting a high-end valve hall of a converter station. The fixed fireproof and anti-explosion plugging structure ischaracterized in that an additional fixed fireproof and anti-explosion door plug is additionally arranged at a joint of a converter transformer and the high-end valve hall, namely on the converter transformer side of an original fireproof plug, the fixed fireproof and anti-explosion door plug is used for fireproof and anti-explosion protection of the high-end valve hall and the converter transformer, H-shaped steel serves as a framework steel beam of the fixed fireproof and anti-explosion door plug, stainless steel square pipes are attached to stainless steel plates to serve as anti-explosiondoor panels, and the middles of the stainless steel square pipes are filled with fireproof materials. The plurality of anti-explosion door panels of the fixed fireproof and anti-explosion door plug in each converter transformer interval are manufactured, and each anti-explosion door panel is connected to the framework steel beam through stainless steel bolts. According to the fixed fireproof andanti-explosion plugging structure, the fireproof and anti-explosion effects are achieved on the converter transformer side, the safety problem of the original fireproof plug on the valve hall side after the converter transformer is burnt out due to fire caused by faults is solved, the fire of the converter transformer is prevented from spreading to the valve hall, and the safety of equipment in the valve hall is guaranteed.

Description

technical field [0001] The invention belongs to the fire safety field of power transmission and transformation equipment in the electric power industry, and specifically belongs to a fixed fireproof and anti-explosion sealing structure for protecting a high-end valve hall of a converter station. 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 valve and the converter transformer are the most important equipment in the converter station. The converter valve is connected to the converter transformer through the bushing on the valve side. However, the converter transformer is the main noise source in the converter station, so it is necessary to adopt corresponding noise reduction schemes to reduce the factory boundary noise of the converter station, so as to achieve environmental friendliness. type grid.
