Why NIOES (NIFPS)
The NIOES (NIFPS) Transformer, found in power plants and substations, is known to be one of the most expensive pieces of equipment. It contains a significant amount of combustible substances, which can pose a fire hazard and lead to power failures and substantial economic losses. Therefore, safeguarding these transformers is of utmost importance.
Conventional systems such as the “High Velocity Water Spray System / CO2 Gas Flooding System” offer external protection by activating when a fire starts around the transformer or when the transformer has already experienced an explosion. In contrast, the “Nitrogen Injection Explosion Prevention & Fire Protection System” provides internal protection by preventing the transformer from exploding in the first place. Transformers are prone to explosions due to factors like overheating, overloading, winding short-circuits, or earth faults. The nitrogen injection system addresses these issues.
It’s important to note that the nitrogen injection system does not protect the transformer from external fires. Instead, it focuses on preventing explosions by injecting nitrogen inside the transformer body. As a result, the “Nitrogen Injection Explosion Prevention System” is not intended as a substitute for the HVWS/CO2 Flooding System. Instead, its installation is recommended as an additional measure alongside the HVWS/CO2 Flooding System to enhance overall transformer protection.
Characteristics of NIOES
State-of-art concept : Rapidly 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.
Fast response : Once a fault signal is detected from the Transformer. The oil is drained within second after detection in order to release pressure and to avoid explosion. The nitrogen gas is injected 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.
Reliability : Utilizing the principle of logic signal to prevent any improper or unnecessary activity to the system and to provide a more flexible system.
High efficiency : Able to inject nitrogen gas continuously for more than 30 minutes to completely cool down the transformer oil as well as prevent and extinguish fire.
Reduce pollution : No Environmental pollution due to the characteristic of nitrogen gas. Extinct fire 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 fire extinction systems, such as water spraying systems and CO2 spraying systems.
Functions : Explosion Prevention and Fire Extinguishing system can extinguish the fire 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 isolated the air from the tank.
Benefits of NIOES
When activated, the system swiftly extinguishes fires within seconds, ensuring rapid fire suppression. Moreover, it effectively prevents transformer explosions from occurring. Nitrogen gas, being inert, does not react with transformer oil, guaranteeing the integrity of the system. Additionally, it is completely non-toxic and non-hazardous, ensuring safety in its operation.
This system provides exceptional cooling capabilities to the transformer oil, aiding in maintaining optimal operating temperatures. It forms an insulating layer of a nitrogen (N2) blanket on the top surface of the oil, further enhancing its protective properties.
One of the advantages of this system is its lower installation and maintenance costs, making it a cost-effective solution. It is also environmentally friendly, aligning with sustainable practices. Furthermore, it is particularly suitable for areas facing water scarcity, making it an ideal choice in such locations.
For external fire protection, the option of the CNF Spray System is available, providing an additional layer of safety and protection, although its use is optional.
Scope of Application
Generator Power is unceasingly increasing with the development of technology, there are many transformer explosion happened due to ineffective of current breaker between the Generator and Power Transformer.
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.
