Energy storage type starter of automatic aerosol extinguishing device

Abstract

The invention discloses an energy storage type starter of an automatic aerosol extinguishing device and belongs to the technical field of extinguishing devices. The problem that an existing starter is overlarge in instantaneous start power is solved. The energy storage type starter comprises a working power supply, an inverter circuit, a rectifying circuit, a current limiting circuit, an energy storage capacitor, a discharging device, a detection controller, a load heating resistor and a load detection device. The working power supply is connected with an overvoltage control relay switch through the inverter circuit, the rectifying circuit and the current limiting circuit. The other end of the overvoltage control relay switch is applied to the positive electrode of the energy storage capacitor through a start control relay switch and a discharging control switch. The discharging device and the energy storage capacitor are arranged in parallel and connected to the discharging control switch. The load heating resistor is connected to the start control relay switch. The load detection device is connected to the start control relay switch. According to the energy storage type starter, the running power consumption is low, energy is saved, all the elements are common, the circuit is simple, the cost is low, and the reliability is high.

Description

technical field [0001] The invention relates to an energy storage type starter of an aerosol automatic fire extinguishing device, belonging to the technical field of fire extinguishing devices. Background technique [0002] The combustion chamber in the aerosol fire extinguishing device is filled with a solid form of fire extinguishing agent. When the fire extinguishing device needs to be activated, the pre-packaged small amount of igniting agent package of agent powder is heated to the ignition point to make it burn, and then the whole agent is ignited. Complete the process of gasification, release and fire extinguishing. Reagents are divided into inert and sensitive agents according to the ratio of ingredients. Among them, the ignition point of inert agents is about 600 degrees. It is precisely because of its high ignition point, strong inertness and good stability that it is widely used. The inert agent is often started by using a resistance heating wire (4-8 ohms) to in...
