Kaasueristettyjä

Kaasueristettyjä refers to gas-insulated electrical equipment. This technology utilizes gases, typically sulfur hexafluoride (SF6), as the primary insulating medium within enclosed compartments. These gases have excellent dielectric properties, meaning they can withstand high electrical stresses without breaking down. This allows for a more compact and robust design compared to traditional air-insulated switchgear.

The main components of kaasueristettyjä systems include circuit breakers, disconnectors, and busbars, all housed within sealed metal enclosures. The gas is maintained at a specific pressure, which is crucial for its insulating capability. In the event of an electrical fault, the gas in the circuit breaker quickly extinguishes the arc, preventing damage to the equipment and ensuring system reliability.

The advantages of kaasueristettyjä technology include its smaller footprint, reduced environmental impact due to less land usage, and enhanced safety as live parts are enclosed. It also offers greater reliability and requires less maintenance compared to older technologies. Kaasueristettyjä is widely used in substations and power transmission networks, particularly in urban areas where space is limited, and in environments where high reliability is paramount. While SF6 is effective, its greenhouse gas properties have led to ongoing research into alternative insulating gases.
