Nitrogen Injection Fire Protection System
NITROGEN INJECTION AND OIL EVACUATION SYSTEMS
(FIRE PREVENTER FOR ELECTRIC TRANSFORMER)
WHY NIOES (NIFPS)
Transformer is among the most expensive
equipment located in power plants and substation etc. They generally contain a large quantity of combustible substance, which can spread re to nearby installations also and caused a power failure and so huge economic losses.
Special attention should be acquired for their safety protection. The traditional System like High Velocity Water Spray System / Co2 Gas Flooding System provides external protection of the transformers and they come into operation once the Fire got initiated around the transformer for the reason whatsoever or in case transformer already got exploded.
Nitrogen injection oil evacuation system for transformer, Whereas Nitrogen Injection Explosion prevention & Fire Protection System is an internal protection of the transformer as it prevents the Transformer from its explosion which generally occurs due to over heating / overloading / winding Short-circuiting or for any earth fault etc. Please note that this system does not protect the transformer from its external Fire,
Nitrogen is put inside the body of the transformer, Therefore Nitrogen Injection Explosion prevention System is not an alternative for HVWS / Co2 Flooding System but its Installation is recommended in addition to HVWS / Co2 Flooding System.
INCIDENTS OF TRANSFORMER FIRE
Nitrogen Put Explosion prevention & Fire Protection System is more advanced Transformer prevention for oil immersed transformers in compare to water spray (HVWS) System and Co2 Flooding System.
HOW TRANSFORMER EXPLODES AND CATCH FIRE
An Arc is generated due to any internal fault in the Transformer and a high energy ows through transformer which lead to decomposition of insulation/oil at high temperature. Top oil surface attains temperature higher than ignition point. Huge thermal energy is generated thereby emitting combustible gases. Pressure built-up resulting in tank rupture normally at top cover. Hot oil when comes in contact with the oxygen catches fire.
BENEFITS OF NITROGEN INJECTION AND OIL EVACUATION SYSTEM
-> On activation, the system extinguish the Fire within seconds.
-> It prevent the Transformer from explosion.
-> Nitrogen Gas is inert and does not react with transformer oil.
-> It is completely Non-Toxic & Non-hazardous.
-> It provides best cooling e ect to the oil inside the Transformer.
-> Forms insulating layer of N2 Blanket on top surface of the oil.
-> Less Cost of Installation & Maintenance.
-> Best System for the Areas of water Scarcity.
-> CNF Diffuse System for External Fire Protection ( Optional ).
OUR SYSTEM’S USP
-> Auto Dialer Facility – a pre-recorded message will be sent to already registered phone
numbers in the system in case of any system activation. (Max 3 numbers).
-> A mechanical interlocking has been provided to ensure that nitrogen injection will not take place into the transformer until the oil drain valve is open.
INJECTION IN THE TRANSFORMER
PRINCIPLE OF EXTINGUISHING EXTERNAL FIRE
OF TRANSFORMER (OPTIONAL)
In case the transformer is on re externally also in addition to the internal problem as need
above for the principle of explosion prevention & Nitrogen Injection, the re detector is activated, the Gas Relay/PRV closes, and the electric breaker switches o . As a result, the system is operated to drain the oil drain valve opens to draw oil. Then nitrogen gas is continuously injected and the Foam Spray System activate, and in this process
the nitrogen gas cools down the transformer INTERNALLY, whereas the Foam Spray extinguishes re EXTERNALLY over the transformer.
CHARACTERISTICS OF NITROGEN INJECTION SYSTEM
Concept: Quickly drain oil to prevent explosion and inject nitrogen to prevent
and extinct fire.
Excellent performance: Utilizing fast valves to drain oil within seconds with the most advanced technique.
Initial response: Once a fault signal is detected from the Transformer. The oil is clear out within second after detection in order to release pressure and to avoid explosion. The nitrogen gas is put after 1 to 20 second in order to mix and cool down the oil, to reduce the concentration of flammable gases, to isolate oxygen gas, and to extinct fire.
Dependability: Utilizing the principle of logic signal to prevent any improper or unnecessary activity to the system and to provide a more flexible system.
High performance: Able to inject nitrogen gas continuously for more than 30 minutes to
completely cool down the transformer oil as well as prevent and extinguish re.
Decrease pollution: No Environmental pollution due to the characteristic of nitrogen
gas. Extinct re without water is an advantage to the lack of water area.
Feasibility: Easy to install and maintain for both new or existing transformers with reasonable investment in a minor price compare to other traditional transformer re
extinction systems, such as water spraying systems and CO2 spraying systems.
Functions: Explosion Prevention and Fire Extinguishing system can extinguish the re immediately with the Nitrogen Gas injected into the Transformer Tank.
The Nitrogen can be injected continuously for 30 Minutes to stir and cool down the transformer oil, which also outlying the air from the tank.
SCOPE OF APPLICATIONS
Generator Power is unceasingly increasing with the development of technology, there are many transformer explosion happened due to active of current breaker between the Generator and Power Transformer.
Our Nitrogen Injection System is suitable for new or remodeled Power transformer which are located in the high power plant, substations, indoor substations, underground substations, city substations and cold water deficient areas.
