A smoldering hazard identification system for electrical fires based on volatile gas detection

Abstract

The invention relates to an electrical fire smoldering hidden danger identification system based on volatile gas detection. The system consists of a polymer pyrolysis volatile gas collection tank, an electromagnetic valve, an air pump, a gas analyzer, an electrical parameter measuring sensor, an electrical parameter measuring instrument, and a processor unit. The electrical parameter measuring sensor is disposed in a power distribution system loop of a monitored physical space, and the output end is connected to the processor unit by the electrical parameter measuring instrument, the polymer pyrolysis volatile gas collection tank is disposed in the monitored physical space, and the gas outlet of the polymer pyrolysis volatile gas collection tank is communicated with an air chamber inlet of the gas analyzer, the air pump pumps the air from the monitored physical space into the air chamber of the gas analyzer through the electromagnetic valve, the output end of the gas analyzer is connected to a gas information input end of the processor unit, and the output control end of the processor unit is interconnected with a fire fighting linkage control system through the Internet, thus realizing rapid identification and early warning of a low-voltage distribution system's electrical fire smoldering hidden danger.

Description

technical field [0001] The invention belongs to the technical field of early monitoring and early warning of electrical fires, in particular to an electrical fire smoldering hidden danger identification system based on fine detection of cable polymer pyrolysis volatile gas. Background technique [0002] The rapid development of the electric power industry has provided a lot of convenience to people's production and life, but with the continuous increase in the number of wires and cables and power electronic equipment, the probability of electrical fires has also increased year by year, seriously threatening people's lives and property safety. Electrical fire refers to a fire caused by electrical energy acting as a fire source or burning material. Generally, it refers to the heat dissipated in the form of excessive temperature, hot surface, arc, etc. due to failure of electrical lines, power supply and distribution equipment, and appliances. The fire is formed by spontaneous ...
