A Transformer Explosion Fire Extinguishing System

Abstract

The invention discloses a fire extinguishing system for a transformer explosion fire. The system consists of a fire location alarm positioning device, an external environment monitoring device, a dry powder fire extinguishing pipe network that can control the injection range, dry powder fire extinguishing equipment, oil discharge-cut-off-nitrogen injection pipeline , Simplified nitrogen injection fire extinguishing equipment, dry powder-nitrogen injection combination system fire alarm linkage controller with various control modules, etc., solves the problem of spreading fires, continuous fires, complex fires caused by severe explosions of transformers that cannot be extinguished by existing transformer fire extinguishing systems The problem of burning fires, and the waste of state investment in existing fire suppression systems.

Description

technical field [0001] The invention relates to the technical field of fire fighting equipment, in particular to an oil-immersed power transformer fire extinguishing system. Background technique [0002] In recent years, as the power equipment put into operation during the peak period of the last round of power construction in my country has entered the upgrading and replacement period, transformer accidents caused by equipment aging and loss have a tendency to increase. On July 10, 2015, a serious explosion and fire occurred in the high-voltage bushing of the 500kV ** single-phase main transformer in ** City, Yunnan Province. According to the analysis of the accident scene, the pipe network of the transformer fire extinguishing system was damaged by the blown bushing and could not be used. The transformer The bushing maintenance flange exploded 50m away, and the transformer oil splashed over the firewall to the adjacent single-phase transformer. Due to the special location ...
