Application of Synthetic Foam Extinguishing System in Power System

Abstract: The basic characteristics of synthetic foam extinguishingsystem

Are presented briefly in this paper. By comparison with other fire

Extinguishing systems, the application of this system in powersystem has the advantages

Of simple design, high effective, more safety and economicallyprofitable.

Keywords: Synthetic Foam, System or ganization, Principle, Design

Abstract: foam spray Fire extinguishing system Is used as a high-performance liquid synthetic foam Extinguishing agent , Under some pressure through a dedicated spray Sprinklers , Jet fire object to the rapid fire. Is especially suitable for power transformers on fire-fighting system. In this paper, the structural composition of the system, working principle and design applications are briefly described.

Keywords: foam spray; system structure; principle; Design

1 System Overview Absorbing foam spray system and foam fire extinguishing the advantages of an "efficient, economic, security, environmental protection," the fire extinguishing system. Its structure, composition, reservoir pressure is used and the driving principle and design applications, the similarity with the water spray system.

Foam spray system features are: advanced and efficient fire extinguishing agent can be used to eliminate A, B, C classes of fire; especially for fighting hot oil flow and power transformer fire; fire extinguishing agent and use a small amount of biodegradable nature, do not pollute the environment, has good insulation properties, had no effect on the equipment; use of gas storage compression power source, and configuration without fire water supply equipment; fire efficient, safe and reliable installation, operation and maintenance.

Foam spray system can be widely used in the following areas: oil immersed power transformers; fuel boiler room; fuel generator room; small oil base; small storage tanks; small garage; small repair garage; ship's cabin and engine compartment.

2 system structure and working principle of the composition

2.1 structure and composition Foam spray system is a synthetic foam with high pressure spray to fire through the objectives of the fire extinguishing system consists of storage tanks, synthetic foam, starting devices, nitrogen-driven devices, electromagnetic control valve, water fog nozzle and pipe network and other components.

Figure 1 System diagram 2.2 works Foam spray system is the use of efficient synthetic foam extinguishing agent stored in the tank in the. When fire, through the automatic fire alarm joint control or manual control; in high-pressure nitrogen gas driven tank to promote the synthesis of foam fire extinguishing agent; through the pipe and spray nozzle, it will foam spray to protect the object ; rapid cooling to protect the object surface, and produce a layer of flame-retardant film, isolation protection of objects and the air so quickly extinguishing the fire extinguishing system. The absorption of the water spraying fire extinguishing system and foam fire extinguishing system characteristics of the system, in fact it is similar to water mist fire extinguishing systems, but use a different fire-fighting agent. As the foam spray system is used within the nitrogen stored in the cylinder inside the tank directly to start the fire extinguishing agent, through the implementation of fire-fighting nozzle exhaust pipe, and, so the same with water mist fire extinguishing system and foam fire fighting system, cooling, asphyxia, emulsification, isolation extinguishing mechanism. The fire extinguishing system equipment is simple, compact arrangement.

Figure 2 system principle diagram 2.3 Control

Foam spray system should generally be set to automatic, manual and emergency operation of three control methods. Can Fire Alarm Joint control or manual control of the controller to open high-pressure nitrogen gas bottle drives the first valve. High-pressure nitrogen gas through the vacuum to achieve the desired working pressure, nitrogen is transported to the tank. When the tank pressure increased to working pressure, the tank exit valve to open immediately, extinguishing agent through the pipe and spray nozzle that is playing in the protection of the object. In addition, the devices should also set the machinery in the emergency boot mode of operation.
