Novel transformer explosion fire extinguishing system

Abstract

The invention discloses a novel transformer explosion fire extinguishing system. The system is composed of a fire portion alarm positioning device, an outer environment monitoring device, a dry powder fire extinguishing pipe network with the controllable jetting range, a dry powder fire extinguishing device, an oil draining-cutoff-nitrogen injection pipeline, a simple type nitrogen injection fire extinguishing device, a dry powder-nitrogen injection combined system fire alarm linkage controller with multiple control modules and other components. The problems that an existing transformer fire extinguishing system cannot put out working fire, continuous fire and after-combustion fire caused by serious explosion of a transformer, and an existing fire extinguishing system wastes national investment are solved.

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 ...
