Abstract

The plugging of the valve hall of the UHV converter station is an important barrier to prevent the fire from spreading to the valve hall, and the heating curve of hydrocarbon fire should be adopted for defense. The fire resistance test results of the rock wool composite aluminum silicate plate under the hydrocarbon fire heating curve show that the plug has good heat insulation and complete performance and meets the three-hour fire resistance requirements. It is a fire protection structure for the valve side casing of the converter station. The retrofit provides a solution. The study of the microscopic mechanism of the disassembled plugging material shows that the phase change reaction of structural rock wool under hydrocarbon fire is the main reason for its sintering.
