Abstract

The invention discloses an ignition system for a fuel gas generator. The ignition system is characterized by comprising an ignition tube (2), an ignition cartridge (1), ignition powder (3), a radio-frequency protection chip (4) and a current protection chip (5); the ignition tube (2) is arranged in the center in the ignition cartridge and is attached to the position of the lower wall of the cartridge, and the ignition powder (3) is arranged in the space formed by the ignition cartridge (1) and the ignition tube (2); and the radio frequency protection chip and the current protection chip are connected with the ignition tube in parallel and then connected with a combustion chamber conducting rod through a wire. The ignition system has the beneficial effects of being resistant to water, damp, static electricity, lightning and electromagnetic irradiation and the like, and the safety of the fuel gas generator in the installing, using, transporting and storing processes and reliable work of the fuel gas generator after the fuel gas generator is stored for a long time in severe environments with high humidity, static electricity, lightning, electromagnetic irradiation and the like are ensured.

Description

technical field [0001] The invention belongs to the technical field of fire protection, and in particular relates to an ignition system suitable for a dry powder automatic fire extinguishing system of a gas generator. Background technique [0002] A gas generator is a device that generates gas with a certain temperature (high temperature) and a certain pressure (high pressure). The gas produced by it has high available energy, because high temperature has high heat energy, and high pressure has high potential energy. . The high-temperature and high-pressure gas with high energy expands further and can do work externally. If the gas generator is in the turbine and expands to do work, the output shaft power will drive the propeller through the reducer to become a turboprop engine, and drive the helicopter rotor to become a turboshaft engine. If the gas generator expands in a gas-driven dry powder automatic fire extinguisher, it acts as a driving force for the dry powder in t...
