When non-flammable, non-polluting transformers are required, Gas Insulated Transformer (GIS) are employed. For instance, they are used where a normal transformer's oil spill would be hazardous to the environment, such as in buildings, locations close to lakes and rivers, and densely populated places. These transformers are also deployed in environmentally crucial regions where oil leakage is forbidden. They include water treatment facilities and hydroelectric power stations. Gas insulated transformers are easily recyclable and environmentally acceptable.
This is one of these transformers' key benefits. Gas insulated switchgear and Gas Insulated Transformer can be combined into a single, enclosed unit. This offers space savings and integrated control over the gas system. The following applications are suitable for SF6 gas-insulated Transformers. Because fire safety is crucial hotels, department stores, schools, and hospitals are examples of buildings. Underground substations and retail centers locations near residential areas, factories, and chemical plants where it is especially important to prevent environmental contamination Zones near water sources, habitations, and coastal regions stations for treating water.
Gas Insulated Transformer, also known as gas insulated power transformers, are a type of transformer that utilizes sulfur hexafluoride (SF6) gas as an insulating medium. This innovative technology has several advantages over traditional oil-insulated transformers, including higher reliability, improved safety, and reduced maintenance requirements.
Gas Insulated Transformer has a unique design that enables them to operate more efficiently than traditional transformers. They are typically smaller in size and weigh less than conventional transformers, making them easier to transport and install.
The key component of a Gas Insulated Transformer is the SF6 gas-insulated tank, which houses the transformer's active parts. This tank is designed to withstand high pressure and is filled with a specific amount of SF6 gas, which serves as both an insulating medium and a coolant.
The transformer's active parts, including the core and windings, are immersed in the SF6 gas, which isolates them from the tank's outer shell. The SF6 gas has excellent insulating properties, with a dielectric strength of approximately three times that of air, making it an ideal insulating medium for high voltage applications.
The SF6 gas also has excellent thermal conductivity, which allows it to efficiently dissipate the heat generated by the transformer's active parts. This helps to reduce the overall size of the transformer, as well as improve its efficiency.
