Gas Fire Differential Simulation Experiment

1. Basic principles and fire extinguishing methods:

According to the requirements of the specification, the system adopts two composition methods: full -drowned unit independent system and combined allocation system. The unit independent system is a set of pipe network systems corresponding to a fire extinguishing device to protect a protective area. The combined system is a set of pipe network systems corresponding to a set of fire extinguishing device to protect the formation of the two upper protection areas.

2. The composition of the tr--ning device of the gas fire extinguishing system:

The pipe network seventeenth fluorine firing device, pipe network, gas fire extinguishing controller, fire detector, sound light alarm, --r deficiency indicator, emergency start -stop button, peripheral power supply, etc. form a complete automatic fire extinguishing system.

2. Control method:

This system m--nly has four control methods: automatic, manual, mechanical emergency manual and emergency start/stop.

(1) Automatic control method: This fire extinguishing controller is equipped with fireworks detectors and fixed temperature temperature sensor detectors. There is a control method on the controller to select the lock. When it is placed in the "automatic" position, the fire extinguishing controller is in an automatic control state. When there is only one detector issuing a fire signal, the controller will send a fire alarm signal to notify the abnormal situation without starting the fire extinguishing device to release the fire extinguishing agent. If the fire extinguishing device is required, you can press the "Emergency Start button" to start the fire extinguishing device to release the fire extinguishing agent and implement the fire extinguishing agent. When the two detectors issued a fire signal at the same time, the controller issued a fire sound and light signal, notifying that the fire occurred, and the relevant personnel should evacuate the scene and issue a linkage instruction to close the linked equipment such as the wind turbine and the fire prevention valve. After that, the fire extinguishing instructions are issued, the solenoid valve is opened, the gas is turned on to open the cont--ner valve, released the fire extinguishing agent, and implements the fire extinguishing; Stopping the twist urgently "can terminate the occurrence of the fire extinguishing instructions. Do not start the fire extinguishing device, release the fire extinguishing agent, and implement the fire extinguishing.

This tr--ning device uses a series PWM charging control method to reduce the voltage loss of the charging circuit compared with the original diode charging method, and the charging efficiency is 3-6%higher than the non -PWM; The automatic control method is conducive to improving the battery life. A variety of protection functions, including battery reverse connection, battery storage, under pressure protection, short -circuit protection of solar battery components, have automatic recovery output overcurrent protection functions, and output short -circuit protection functions.
