Please visit our global website Language Diaphragm Pumps Safeguard Insulating Gas of Electrical Systems For the safe handling of electrical currents in medium to high voltage applications, insulating gases such as SF6 are essential for the protection of electrical systems. Having a significant impact on the environment, they require strictly closed systems. Insulating gases, such as sulfur hexafluoride, play a critical role in protecting electrical systems. They are widely used in high-voltage power systems, switchgears and transformers to ensure operational safety, reduce the risk of electrical failures and short circuits. Their unique properties also allow smaller clearances between electrical components. However, the particularly high global warming potential of sulfur hexafluoride requires the strict safety of closed systems to prevent the gas from escaping into the environment. SF6 Gas for Circuit Breaker and Switchgear Safety Diaphragm Pumps Maintain the Integrity of High-Voltage Systems To ensure gas tightness and prevent SF6 leakage, diaphragm pumps play a key role in protecting the integrity of high-voltage systems and contributing to environmental responsibility. Diaphragm pumps can perform three important functions to maintain a closed system and safely handle the insulating gas. Extract SF6: Diaphragm pumps are used to efficiently and safely extract SF6 gas from the system during maintenance or repair operations. These pumps ensure that the gas is removed without leakage or emissions, maintaining the integrity of the system. Evacuate Air or Nitrogen: Diaphragm pumps play a critical role in creating a clean and controlled environment within the system by effectively evacuating air or nitrogen. By removing unwanted gases, the pumps help maintain the purity of the SF6 gas and prevent contamination, ensuring optimal performance. Refill SF6: After evacuation and cleaning, diaphragm pumps are responsible for refilling the system with SF6 gas. Their precise control of pressure and flow enables accurate and efficient replenishment, ensuring that the system remains properly insulated and operates safely and reliably. Efficiency Through Customization With adaptations such as stainless steel piping and increased tightness of ≤ 1x10-4 mbar x l/s, diaphragm pumps, such as the KNF N 1400, also allow precise control of pressure and flow rate to ensure optimum delivery of sulfur hexafluoride to the insulation system. This not only ensures reliable insulation, but also minimizes the risk of leakage and environmental impact. Learn more about KNF diaphragm pump customization.
